+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+		   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/philosophy/why-not-lgpl.html>.

+	* configure.in (x86_64-*-*): Try also "-march=k8 -mno-sse2", in case
+	we're in ABI=32 on an old OS not supporting xmm regs.
+	(GMP_GCC_PENTIUM4_SSE2, GMP_OS_X86_XMM): Run these tests under
+	-march=k8 too, and not under ABI=64.
+
+	* doc/gmp.texi (Converting Integers): For mpz_get_d, note truncation
+	and overflows.  For mpz_get_d_2exp note truncation, note result if

+2004-05-01  Kevin Ryde  <kevin@swox.se>
+
+	* doc/gmp.texi (References): Update gcc online docs url to
+	gcc.gnu.org.
+
+	* configure.in (mips*-*-irix[6789]*): Correction to m4 quoting of this

+
+2004-04-30  Kevin Ryde  <kevin@swox.se>
+
+	* acinclude.m4 (GMP_PROG_CC_X86_GOT_EAX_EMITTED,

+
+	* longlong.h (count_leading_zeros_gcc_clz,

+	mpz/cfdiv_r_2exp.c, mpq/aors.c, mpf/ceilfloor.c: Give REGPARM_ATTR()

+
+	* tests/rand/t-lc2exp.c (check_bigc1): New test.
+
+	* doc/fdl.texi: Tweak @appendixsubsec -> @appendixsec to match our

+	support @appendixsubsec directly within an @appendix.
+
+2004-04-20  Kevin Ryde  <kevin@swox.se>
+
+	* doc/texinfo.tex: Update to 2004-04-07.08 from texinfo 4.7.
+	* doc/gmp.texi, mpfr/mpfr.texi (@copying): Don't put a line break in
+	@ref within @copying, recent texinfo.tex doesn't like that.

+	DLLs.
+
+	* */Makefile.in, install-sh: Update to automake 1.8.3.

+	PACKAGE_VERSION now used by autoconf.
+	(what_objects): Only demand 9 object files, as for instance occurs in
+	the scanf directory.
+	(asm files): Transform labels L(foo) -> Lfoo.  Take func name from

+
+2004-04-07  Kevin Ryde  <kevin@swox.se>
+
+	* mpn/x86/k6/gcd_finda.asm: Correction jbe -> jb in initial setups.
+	Zero flag is wrong here, it relects only the high limb of the compare,
+	leading to n1>=n2 not satisfied and wrong results.  cp[1]==0x7FFFFFFF
+	with cp[0]>=0x80000001 provokes this.
+
+	* doc/gmp.texi (BSD Compatible Functions): Note "pow" name clash under
+	the pow function description too.
+	(Language Bindings): Add XEmacs (betas at this stage).  Reported by
+	Jerry James.
+
+	* tests/refmpn.c (refmpn_mod2): Correction to ASSERTs, r==a is allowed.
+
+	* gen-psqr.c (generate_mod): Cast mpz_invert_ui_2exp args, for K&R.
+	* gen-bases.c, gen-fib.c, gen-psqr.c: For mpz_out_str, use stdout

+
+2004-04-04  Kevin Ryde  <kevin@swox.se>
+
+	* gmp-impl.h (BSWAP_LIMB) [amd64]: New macro.

+
+2004-03-20  Kevin Ryde  <kevin@swox.se>
+
+	* longlong.h (power, powerpc): Add comments on how we select this code.
+
+	* gmp-h.in (mpz_get_ui): Use ?: instead of mask style, gcc treats the
+	two identically but ?: is a bit clearer.
+
+	* insert-dbl.c: Remove file, no longer used, scaling is now integrated
+	in mpn_get_d.
+	* Makefile.am (libgmp_la_SOURCES): Remove insert-dbl.c.

+	* tests/mpf/t-mul_ui.c: New file.
+	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.
+
+	* mpf/div.c: Use mpn_tdiv_qr.  Use just one TMP_ALLOC.  Use full

+
+	* mpn/generic/sb_divrem_mn.c: Correct header comment.
+
+2004-03-11  Kevin Ryde  <kevin@swox.se>
+
+	* aclocal.m4, configure, ltmain.sh: Downgrade to libtool 1.5, version
+	1.5.2 doesn't remove .libs/*.a files when rebuilding, which is bad for
+	development when changing contents or with duplicate named files like
+	we have.
+
+	Revert this, ie restore AR_FLAGS=cq:
+	* acinclude.m4 (GMP_PROG_AR): Remove AR_FLAGS=cq, libtool 1.5.2 now
+	does this itself on detecting duplicate object filenames in piecewise
+	linking mode.
+
+	* randbui.c, randmui.c [longlong+nails]: Correction to conditionals
+	for second limb.
+
+	* mpz/aors_ui.h, mpz/cdiv_q_ui.c, mpz/cdiv_qr_ui.c, mpz/cdiv_r_ui.c,

+	[longlong+nails]: Amend #if to avoid warnings about shift amount.
+
+2004-03-07  Kevin Ryde  <kevin@swox.se>
+
+	* mpf/reldiff.c: Use rprec+ysize limbs for d, to ensure accurate
+	result.  Inline mpf_abs(d,d) and mpf_cmp_ui(x,0), and rate the latter
+	UNLIKELY.
+
+	* mpf/ui_div.c: Use mpn_tdiv_qr.  Use just one TMP_ALLOC.  Use full
+	divisor, since truncating can lose accuracy.
+	* tests/mpf/t-ui_div.c: New file.
+	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.
+
+	* mpf/set_q.c: Expand TMP_ALLOC_LIMBS_2, to make conditional clearer
+	and avoid 1 limb alloc when not wanted.
+
+	* gmp-impl.h (WANT_TMP_DEBUG): Define to 0 if not defined.
+	(TMP_ALLOC_LIMBS_2): Use "if" within macro rather than "#if", for less

+
+	* tests/refmpn.c (refmpn_sb_divrem_mn, refmpn_tdiv_qr): Nailify.

+	of K&R.
+	* tests/mpn/t-perfsqr.c (PERFSQR_MOD_1): Use CNST_LIMB for K&R.
+
+	* doc/configuration (Configure): Remove mkinstalldirs, no longer used.
+
+	* acinclude.m4 (GMP_PROG_AR): Remove AR_FLAGS=cq, libtool 1.5.2 now
+	does this itself on detecting duplicate object filenames in piecewise
+	linking mode.
+
+	* configure.in (hppa2.0*-*-*): Test sizeof(long) == 4 or 8 to verify
+	ABI=2.0n versus ABI=2.0w.  In particular this lets CC=cc_bundled
+	correctly fall back to ABI=2.0n (we don't automatically add CC=+DD64
+	to that compiler, currently).
+
+	* doc/gmp.texi (Reentrancy): Note C++ mpf_class constructors using
+	global default precision.
+	(Random State Miscellaneous): Describe gmp_urandomb_ui as giving N
+	bits.
+	(C++ Interface Floats): Describe operator= copying the value, not the
+	precision, and what this can mean about copy constructor versus
+	default constructor plus assignment.
+
+	* mpf/set_q.c: Use mpn_tdiv_qr rather than mpn_divrem, so no shifting.
+	Don't truncate the divisor, it can make the result inaccurate.
+	* tests/mpf/t-set_q.c: New file.
+	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.
+
+	* mpf/set.c: Use MPN_COPY_INCR, in case r==u and ABSIZ(u) > PREC(r)+1.
+	No actual bug here, because MPN_COPY has thusfar been an alias for
+	MPN_COPY_INCR, only an ASSERT failure.
+	* tests/mpf/t-set.c: New file.
+	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.
+
+	* mpf/set.c, mpf/iset.c: Do MPN_COPY last, for possible tail call.
+
+	* mpf/set_d.c: Rate d==0 as UNLIKELY.  Store size before extract call,
+	to shorten lifespan of "negative".
+
+	* mpf/init.c, mpf/init2.c, mpf/iset_d.c, mpf/iset_si.c,
+	mpf/iset_str.c, mpf/iset_ui.c: Store prec before alloc call, for one
+	less live quantity across that call.
+	* mpf/init.c, mpf/init2.c, mpf/iset_str.c: Store size and exp before
+	alloc call, to overlap with other operations.
+
+	* tests/refmpf.c, tests/tests.h (refmpf_fill, refmpf_normalize,
+	refmpf_validate, refmpf_validate_division): New functions.
+
+	* tests/refmpn.c, tests/tests.h (refmpn_copy_extend,

+
+	* tests/cxx/t-istream.cc (check_mpz, check_mpq, check_mpf): Use size_t
+	for loop index, to quieten g++ warning.

+
+	With Karl Hasselström:
+	* mpn/generic/dc_divrem_n.c (mpn_dc_div_2_by_1): New function, with
+	meat from old mpn_dc_divrem_n.  Accept scratch parameter.  Rewrite to
+	avoid a recursive call.
+	(mpn_dc_div_3_by_2): New function, with meat from old
+	mpn_dc_div_3_halves_by_2.  Accept scratch parameter.
+	(mpn_dc_divrem_n): Now just allocate scratch space and call new
+	mpn_dc_div_2_by_1.
+
+2004-02-29  Kevin Ryde  <kevin@swox.se>
+
+	* longlong.h (count_leading_zeros) [alpha gcc]: New version, inlining

+
+	* aclocal.m4, configure, install-sh, missing, ltmain.sh,

+
+	* tune/time.c (speed_endtime): Return 0.0 for negative time measured.
+	Revise usage comments for clarity.

+	failed measurement.
+
+	* tests/mpn/t-get_d.c (check_rand): Correction to nhigh_mask setup.

+
+2004-02-27  Kevin Ryde  <kevin@swox.se>
+
+	* tests/devel/try.c: Add a comment that this is not for Cray systems.
+
+	* mpf/set_q.c: Don't support den(q)<0, demand canonical form in the
+	usual way.
+
+2004-02-24  Torbjorn Granlund  <tege@swox.com>
+
+	From Kevin:
+	* mpn/generic/mul_fft.c (mpn_fft_add_modF): Loop until normalization
+	criterion met.
+
+2004-02-22  Kevin Ryde  <kevin@swox.se>
+
+	* acinclude.m4 (GMP_PROG_CC_WORKS, GMP_OS_X86_XMM, GMP_PROG_CXX_WORKS):
+	Remove files that might look like compiler output, so our "||"
+	alternatives are not fooled.
+
+	* acinclude.m4 (GMP_PROG_CC_WORKS): Add test for lshift_com code
+	mis-compiled by certain IA-64 HP cc at +O3.
+
+	* gmp-impl.h (USE_LEADING_REGPARM): Disable under prof or gprof, for

+	AC_DEFINEs.
+
+2004-02-21  Kevin Ryde  <kevin@swox.se>
+
+	* configure.in (sparc64-*-*bsd*): Amend -m32 setup for ABI=32, so it's
+	not used in ABI=64 on the BSD systems.
+
+2004-02-18  Niels Möller  <nisse@lysator.liu.se>
+
+	* tests/mpz/t-gcd.c (gcdext_valid_p): New function.
+	(ref_mpz_gcd): Deleted function.
+	(one_test): Rearranged to call mpz_gcdext first, so that the
+	returned value can be validated.

+
+	* configure.in, acinclude.m4 (GMP_PROG_HOST_CC): Remove, libtool no

+
+                          INSTALLING GNU MP
+                          =================
+
+
+These instructions are only for the impatient.  Others should read the install
+instructions in gmp.info.  Use
+
+	info -f doc/gmp.info
+
+from the gmp source directory.
+
+Here are some brief instructions on how to install GMP.  First you need to
+compile.  Since you're impatient, try this
+
+	./configure
+	make
+	make check		<= VERY IMPORTANT!!
+
+If that fails, or you care about the performance of GMP, you need to read the
+full instructions in the chapter "Installing GMP" in the manual.
+
+You should not skip the "make check" part; the risk that the GMP sources are
+miscompiled are unfortunately quite high.  And if they indeed are, "make check"
+is very likely to trigger the compiler-introduced bug.
+
+Optionally, you can install the library with the following command.  This will
+be to /usr/local by default, and you'll probably need to be "root" to be able
+to write there.
+
+	make install
+
+To create the printable documentation from the texinfo source, type "make
+gmp.dvi" or "make gmp.ps".  This requires various "tex" commands.
+
+If you are new to GMP, it is a good idea you at least read the chapter "GMP
+Basics" in the manual.
+
+Some known build problems are noted in the "Installing GMP" chapter of
+the manual.  Please report other problems to gmp-bugs@gmplib.org.
+
+The GMP web site is located here: https://gmplib.org/.

+
+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+
+Changes between GMP version 6.1.* and 6.2.0
+
+  BUGS FIXED
+  * gmp_snprintf now correctly reports an error (returns -1) when snprintf
+    does.
+
+  * Conversion to double is now more robust even if the configuration process
+    does not recognize the float format.
+
+  * mpz_powm could return a not completely normalised value, when the
+    exponent was 1 and the base < 0.
+
+  * mpf_set_str could create invalid mpf_t variables for input strings with
+    many leading zeros.
+
+  FEATURES
+  * New C++ functions factorial, primorial and fibonacci for mpz_class.
+
+  * Functions to detect primality now substitute the first 24 Miller-Rabin
+    iterations with the BPSW test.
+
+  * Mini-GMP: new functions mpz_2fac_ui and mpz_mfac_uiui.
+
+  * Mini-GMP: mpz_sizeinbase, mpz_get_str, and mpz_set_str now support bases up
+    to 62.
+
+  * Mini-GMP: added support for the mpq_t layer.
+
+  * MIPS r6 cores are now supported.
+
+  SPEEDUPS
+  * Major speedup for AMD Ryzen and Epyc thanks to an extensive set of assembly
+    code.
+
+  * Major speedup for IBM POWER9 thanks to assembly code making use of new madd
+    instruction.
+
+  * Speedup for 64-bit ARM CPUs thanks to new/improved assembly code.
+
+  * The n-over-k function mpz_bin_ui has been reimplemented for great speedups
+    for large operands.
+
+  * Speedup for the worst case of mpz_perfect_power_p.
+
+  * Speedup for gcd for small and medium size operands.
+
+  * Speedup for really huge multiplies thanks to much larger FFT tables.
+
+  MISC
+  * Internal representation of the mpz_t variables now supports lazy
+    allocation; memory is allocated only when a value is stored.
+
+  * Small improvements and better coverage for the test suite.
+
+  * The tune/speed program can measure some more functions.
+
+  * The low-level function mpn_mul no longer diverts to mpn_sqr, users should
+    call mpn_sqr directly when applicable.
+
+  * New installed files gmp.pc and gmpxx.pc, for use with pkg-config.
+    Contributed by Hugh McMaster.
+
+Changes between GMP version 6.1.1 and 6.1.2
+
+  BUGS FIXED
+  * Mini-GMP: Fixed a division bug, which on a machine with 64-bit
+    unsigned long affects approximately 1 out of 2^32 divisors.
+
+  * Mini-GMP: Fix mpz_set_str crash on inputs with a large number of
+    leading zeros. Also stricter input validation, rejecting inputs
+    with no digits.
+
+  FEATURES
+  * Handle more systems which require PIC code in static libraries (e.g.,
+    "hardened" Gentoo and Debian 9).
+
+  * Configuration for arm (-32 and -64) has been rewritten, fixing poor
+    code selection for many CPUs.
+
+  * Mini-GMP: Updated to the latest development version, including
+    new functions mpn_com and mpn_neg.
+
+  SPEEDUPS
+  * None, except for arm CPUs affected by the configuration rewrite.
+
+  MISC
+  -
+
+Changes between GMP version 6.1.0 and 6.1.1
+
+  BUGS FIXED
+  * Make Intel Broadwell configurations work on Windows.
+
+  FEATURES
+  * Work around faulty cpuid on some recent Intel chips (this allows GMP to run
+    on Skylake Pentiums).
+
+  * Support thumb-less ARM chips.
+
+Changes between GMP version 6.0.* and 6.1.0
+
+  BUGS FIXED
+  * The public function mpn_com is now correctly declared in gmp.h.
+
+  * Healed possible failures of mpn_sec_sqr for non-cryptographic sizes for
+    some obsolete CPUs.
+
+  * The option --disable-assembly now disables all inlined asm.
+
+  * Fixed bug affecting mini-gmp's bitwise functions mpz_setbit, mpz_clrbit,
+    and mpz_combit.
+
+  * Various problems related to precision for mpf have been fixed.
+
+  * Fixed ABI incompatible stack alignment in calls from assembly code.
+
+  * Fixed PIC bug in popcount affecting Intel processors using the 32-bit ABI.
+
+  SPEEDUPS
+  * Speedup for Intel Broadwell and Skylake through assembly code making use of
+    new ADX instructions.
+
+  * Square root is now faster when the remainder is not needed. Also the speed
+    to compute the k-th root improved, for small sizes.
+
+  * Improved arm64 support.
+
+  FEATURES
+  * New C++ functions gcd and lcm for mpz_class.
+
+  * New public mpn functions mpn_divexact_1, mpn_zero_p, and mpn_cnd_swap.
+
+  * New public mpq_cmp_z function, to efficiently compare rationals with
+    integers.
+
+  * Support for Darwin in all x86 code, thereby enabling fat builds on Darwin.
+
+  * Support for more 32-bit arm processors.
+
+  * Support for compilation with clang/llvm on more platforms.  Caution: GMP
+    triggers mis-compilation bugs in clang for many platforms, such as arm, x86
+    (32-bit and 64-bit), powerpc, mips.
+
+  * Support for AVX-less modern x86 CPUs. (Such support might be missing either
+    because the CPU vendor chose to disable AVX, or because the running kernel
+    lacks AVX context switch support.)
+
+  * Stack usage trimmed; we believe 512 KiB is now sufficient for any GMP
+    call, irrespective of operand size.
+
+  * Support for NetBSD under Xen; we switch off AVX unconditionally under
+    NetBSD since a bug in NetBSD makes AVX fail under Xen.
+
+  MISC
+  * We now use manufacturers' code names for x86 CPUs, e.g., "haswell" instead
+    of names derived from the commercial brands.
+
+  * Small improvements and better coverage for the test suite.
+
+  * The various FreeBSD problems listed for 6.0.0 affect this release too.
+
+  * Tuned values for FFT multiplications are provided for larger number on
+    many platforms.
+
+Changes between GMP version 5.1.* and 6.0.0
+
+  BUGS FIXED
+  * The function mpz_invert now considers any number invertible in Z/1Z.
+
+  * The mpn multiply code now handles operands of more than 2^31 limbs
+    correctly.  (Note however that the mpz code is limited to 2^32 bits on
+    32-bit hosts and 2^37 bits on 64-bit hosts.)
+
+  * Contains all fixes from release 5.1.3.
+
+  SPEEDUPS
+  * Plain division of large operands is faster and more monotonous in operand
+    size.
+
+  * Major speedup for ARM, in particular ARM Cortex-A15, thanks to improved
+    assembly.
+
+  * Major speedup for SPARC T4/T5 and speedup also for T3, thanks to a lot of
+    new assembly.
+
+  * Speedup for Intel Sandy Bridge, Ivy Bridge, Haswell, thanks to rewritten
+    and vastly expanded assembly support.  Speedup also for the older Core 2
+    and Nehalem.
+
+  * Faster mixed arithmetic between mpq_class and double.
+
+  * With g++, optimise more operations when one argument is a simple constant.
+
+  FEATURES
+  * Support for new Intel and AMD CPUs.
+
+  * Support for ARM64 alias Aarch64 alias ARMv8.
+
+  * New public functions mpn_sec_mul and mpn_sec_sqr, implementing side-channel
+    silent multiplication and squaring.
+
+  * New public functions mpn_sec_div_qr and mpn_sec_div_r, implementing
+    side-channel silent division.
+
+  * New public functions mpn_cnd_add_n and mpn_cnd_sub_n.  Side-channel silent
+    conditional addition and subtraction.
+
+  * New public function mpn_sec_powm, implementing side-channel silent modexp.
+
+  * New public function mpn_sec_invert, implementing side-channel silent
+    modular inversion.
+
+  * Better support for applications which use the mpz_t type, but nevertheless
+    need to call some of the lower-level mpn functions.  See the documentation
+    for mpz_limbs_read and related functions.
+
+  MISC
+  * This release will not work on NetBSD 5.x, FreeBSD 7.x, 8.x or 9 series
+    before 9.3.  The reason is that the m4 command is not correctly
+    implemented.  (Workaround: Use an older GMP release, or install GNU m4 from
+    /usr/ports and tell GMP to use it.)
+
+  * This release will not build properly on FreeBSD/amd64 before version 10
+    using the 32-bit ABI (once a working m4 is installed).  The reason is
+    broken limits.h.  (Workaround: Use an older GMP release if using the 32-bit
+    ABI on these FreeBSD releases is important.)
+
+  * This release will not work reliably on FreeBSD 10.0 for i386 or amd64 using
+    the 32-bit ABI.  The reason is bugs in the compiler 'clang'.  Depending on
+    CPU-dependent compiler flags, GMP may or may not be miscompiled in a
+    particular build.  (Workaround: Compiling gcc from /usr/ports should work,
+    except that gcc circularly depends on GMP; we have not been able to test
+    that workaround due to FreeBSD 10.0 bugs affecting its ability to run under
+    KVM and Xen.)
+
+  * This release will not compile on FreeBSD before version 10 for i386,
+    targeting any modern AMD processor.  The reason is bugs in the old gcc
+    bundled with FreeBSD.  (Workaround: install a less obsolete gcc from
+    /usr/ports and tell GMP to use it, or override the -march=amdfam10
+    GMP configure command line argument.)
+
+
+Changes between GMP version 5.1.2 and 5.1.3
+
+  BUGS FIXED
+  * The internal functions mpn_sbpi1_div_qr_sec mpn_sbpi1_div_r_sec could
+    compute garbage with a low probability.  They are now rewritten, and the
+    test code has been improved.
+
+  * A bug in the ia64 implementation of mpn_divrem_2, clobbering some
+    callee-save registers, has been fixed. This is an internal
+    function, with the bug manifesting itself as miscomputation in,
+    e.g., mpn_sqrtrem.
+
+  * The documentation now correctly says 'const' for input arguments.
+
+  SPEEDUPS
+  * None.
+
+  FEATURES
+  * None.
+
+  MISC
+  * None.
+
+
+Changes between GMP version 5.1.1 and 5.1.2
+
+  BUGS FIXED
+  * A bug in mpz_powm_ui triggered by base arguments of at least 15000 decimal
+    digits or mod arguments of at least 7500 decimal digits has been fixed.
+
+  * An AMD Bulldozer specific bug affecting the 64-bit Windows ABI has been
+    fixed.  This bug was in a key function (mpn_mul_1) and made both Bulldozer
+    specific builds and fat builds run on Bulldozer completely non-functional.
+
+  SPEEDUPS
+  * None.
+
+  FEATURES
+  * None.
+
+  MISC
+  * Fixes and generalisations to the test suite.
+
+  * Minor portability enhancements.
+
+
+Changes between GMP version 5.1.0 and 5.1.1
+
+  BUGS FIXED
+  * On Windows 64-bit, an error causing link errors about
+    __gmp_binvert_limb_table has been fixed.
+
+  * Aarch64 alias ARM64 support now works.
+
+  * A possible buffer overrun in mpz_ior has been fixed.
+
+  * A rare sign flip in mpz_remove has been fixed.
+
+  * A bug causing problems with mpf numbers with absolute value >= 2^31 has
+    been fixed.
+
+  * Several bugs in mini-gmp have been fixed.
+
+  * A bug caused by automake, related to the 'distcheck' target, has been fixed
+    by upgrading the automake used for GMP release engineering.
+
+  SPEEDUPS
+  * None.
+
+  FEATURES
+  * Preliminary support for the x32 ABI under x86-64.
+
+  MISC
+  * The mini-gmp testsuite now tests the entire set of functions.
+
+  * Various improvements of the GMP testsuite.
+
+
+Changes between GMP version 5.0.* and 5.1.0
+
+  BUGS FIXED
+  * When reading a C++ number (like mpz_class) in an istream reaches the end
+    of the stream, the eofbit is now set.
+
+  * The result sign of mpz_rootrem's remainder is now always correct.
+
+  * The mpz_remove function now handles negative divisors.
+
+  * Contains all fixes from release 5.0.5.
+
+  SPEEDUPS
+  * The n-factorial and n-over-k functions have been reimplemented for great
+    speedups for small and large operands.
+
+  * New subquadratic algorithm for the Kronecker/Jacobi/Legendre symbol.
+
+  * Major speedup for ARM, in particular ARM Cortex-A9 and A15, thanks to broad
+    assembly support.
+
+  * Significant speedup for POWER6 and POWER7 thanks to improved assembly.
+
+  * The performance under M$ Windows' 64-bit ABI has been greatly improved
+    thanks to complete assembly support.
+
+  * Minor speed improvements of many functions and for many platforms.
+
+  FEATURES
+  * Many new CPUs recognised.
+
+  * New functions for multi-factorials, and primorial: mpz_2fac_ui,
+    mpz_mfac_uiui and mpz_primorial_ui.
+
+  * The mpz_powm_sec function now uses side-channel silent division for
+    converting into Montgomery residues.
+
+  * The fat binary mechanism is now more robust in its CPU recognition.
+
+  MISC
+  * Inclusion of assembly code is now controlled by the configure options
+    --enable-assembly and --disable-assembly.  The "none" CPU target is gone.
+
+  * In C++, the conversions mpq_class->mpz_class, mpf_class->mpz_class and
+    mpf_class->mpq_class are now explicit.
+
+  * Includes "mini-gmp", a small, portable, but less efficient, implementation
+    of a subset of GMP's mpn and mpz interfaces. Used in GMP bootstrap, but it
+    can also be bundled with applications as a fallback when the real GMP
+    library is unavailable.
+
+  * The ABIs under AIX are no longer called aix32 and aix64, but mode64 and 32.
+    This is more consistent with other powerpc systems.
+
+  * The coverage of the testsuite has been improved, using the lcov tool.  See
+    also https://gmplib.org/devel/lcov/.
+
+  * It is now possible to compile GMP using a C++ compiler.
+
+  * K&R C compilers are no longer supported.
+
+  * The BSD MP compatibility functions have been removed.
+
+
+Changes between GMP version 5.0.4 and 5.0.5
+
+  BUGS FIXED
+  * A bug causing AMD 11h processors to be treated like AMD 10h has been fixed.
+    The 11h processors do not correctly handle all 10h (aka K10) instructions,
+    and GMP's use of these instructions results in major miscomputations (not
+    as one would have hoped CPU traps of some 'illegal instruction' sort).
+
+  * A bug affecting recent Intel Sandy Bridge CPUs resulting in configuration
+    failures has been fixed.
+
+  SPEEDUPS
+  * None.
+
+  FEATURES
+  * A couple of tests added to the self-check suite.
+
+  MISC
+  * None.
+
+
+Changes between GMP version 5.0.3 and 5.0.4
+
+  BUGS FIXED
+  * Thresholds in mpn_powm_sec for both fat and non-fat builds are now used
+    safely, plugging a one-word buffer overrun introduced in the 5.0.3 release
+    (for non-fat) and a multi-word buffer overrun that existed since 5.0 (for
+    fat).  (We have not been able to provoke malign stack smashing in any of
+    the ~100 configurations explored by the GMP nightly builds, but the bug
+    should be assumed to be exploitable.)
+
+  * Two bugs in multiplication code causing incorrect computation with
+    extremely low probability have been fixed.
+
+  * A bug in the test suite causing buffer overruns during "make check",
+    sometimes leading to subsequent malloc crashes, has been fixed.
+
+  * Two bugs in the gcd code have been fixed.  They could lead to incorrect
+    results, but for uniformly distributed random operands, the likelihood for
+    that is infinitesimally small.  (There was also a third bug, but that was
+    an incorrect ASSERT, which furthermore was not enabled by default.)
+
+  * A bug affecting 32-bit PowerPC division has been fixed.  The bug caused
+    miscomputation for certain divisors in the range 2^32 ... 2^64-1 (about 1
+    in 2^30 of these).
+
+  SPEEDUPS
+  * None, except indirectly through recognition of new CPUs, and through better
+    tuning parameters.
+
+  FEATURES
+  * Some more tests added to the self-check suite.
+
+  * The AMD "Bulldozer" CPU is now recognised.
+
+  MISC
+  * None.
+
+
+Changes between GMP version 5.0.2 and 5.0.3
+
+  BUGS FIXED
+  * A few minor bugs related to portability fixed.
+
+  * A slight timing leak of the powm_sec functions have been sealed.  (This
+    leak could possibly be used to extract the most significant few bits of the
+    exponent.  "Few" here means at most 10.)
+
+  * The mpz_nextprime function now runs a safer number of pseudo-random prime
+    tests.
+
+  * A bug in division code possibly causing incorrect computation was fixed.
+
+  SPEEDUPS
+  * None, except indirectly through recognition of new CPUs, and through better
+    tuning parameters.
+
+  FEATURES
+  * New CPUs recognised.
+
+  * IBM S/390 are now supported in both 31/32-bit and 64-bit mode.  (We have
+    not been able to fully test this on any multilib machine, since IBM expired
+    our guest account a few days before our release.)
+
+  MISC
+  * None.
+
+
+Changes between GMP version 5.0.1 and 5.0.2
+
+  BUGS FIXED
+  * Many minor bugs related to portability fixed.
+
+  * The support for HPPA 2.0N now works, after an assembly bug fix.
+
+  * A test case type error has been fixed.  The symptom of this bug was
+    spurious 'make check' failures.
+
+  SPEEDUPS
+  * None, except indirectly through recognition of new CPUs.
+
+  FEATURES
+  * Fat builds are now supported for 64-bit x86 processors also under Darwin.
+
+  MISC
+  * None.
+
+
+Changes between GMP version 5.0.0 and 5.0.1
+
+  BUGS FIXED
+  * Fat builds fixed.
+
+  * Fixed crash for huge multiplies when old FFT_TABLE2 type of parameter
+    selection tables' sentinel was smaller than multiplied operands.
+
+  * The solib numbers now reflect the removal of the documented but preliminary
+    mpn_bdivmod function; we correctly flag incompatibility with GMP 4.3.  GMP
+    5.0.0 has this wrong, and should perhaps be uninstalled to avoid confusion.
+
+  SPEEDUPS
+  * Multiplication of large numbers has indirectly been sped up through better
+    FFT tuning and processor recognition.  Since many operations depend on
+    multiplication, there will be a general speedup.
+
+  FEATURES
+  * More Core i3, i5 an Core i7 processor models are recognised.
+
+  * Fixes and workarounds for Mac OS quirks should make this GMP version build
+    using many of the different versions of "Xcode".
+
+  MISC
+  * The amount of scratch memory needed for multiplication of huge numbers has
+    been reduced substantially (but is still larger than in GMP 4.3.)
+
+  * Likewise, the amount of scratch memory needed for division of large numbers
+    has been reduced substantially.
+
+  * The FFT tuning code of tune/tuneup.c has been completely rewritten, and
+    new, large FFT parameter selection tables are provided for many machines.
+
+  * Upgraded to the latest autoconf, automake, libtool.
+
+
+Changes between GMP version 4.3.X and 5.0.0
+
+  BUGS FIXED
+  * None (contains the same fixes as release 4.3.2).
+
+  SPEEDUPS
+  * Multiplication has been overhauled:
+    (1) Multiplication of larger same size operands has been improved with
+        the addition of two new Toom functions and a new internal function
+        mpn_mulmod_bnm1 (computing U * V mod (B^n-1), B being the word base.
+        This latter function is used for the largest products, waiting for a
+        better Schoenhage-Strassen U * V mod (B^n+1) implementation.
+    (2) Likewise for squaring.
+    (3) Multiplication of different size operands has been improved with the
+        addition of many new Toom function, and by selecting underlying
+        functions better from the main multiply functions.
+
+  * Division and mod have been overhauled:
+    (1) Plain "schoolbook" division is reimplemented using faster quotient
+        approximation.
+    (2) Division Q = N/D, R = N mod D where both the quotient and remainder
+        are needed now runs in time O(M(log(N))).  This is an improvement of
+        a factor log(log(N))
+    (3) Division where just the quotient is needed is now O(M(log(Q))) on
+        average.
+    (4) Modulo operations using Montgomery REDC form now take time O(M(n)).
+    (5) Exact division Q = N/D by means of mpz_divexact has been improved
+        for all sizes, and now runs in time O(M(log(N))).
+
+  * The function mpz_powm is now faster for all sizes.  Its complexity has
+    gone from O(M(n)log(n)m) to O(M(n)m) where n is the size of the modulo
+    argument and m is the size of the exponent.  It is also radically
+    faster for even modulus, since it now partially factors such modulus
+    and performs two smaller modexp operations, then uses CRT.
+
+  * The internal support for multiplication yielding just the lower n limbs
+    has been improved by using Mulders' algorithm.
+
+  * Computation of inverses, both plain 1/N and 1/N mod B^n have been
+    improved by using well-tuned Newton iterations, and wrap-around
+    multiplication using mpn_mulmod_bnm1.
+
+  * A new algorithm makes mpz_perfect_power_p asymptotically faster.
+
+  * The function mpz_remove uses a much faster algorithm, is better tuned,
+    and also benefits from the division improvements.
+
+  * Intel Atom and VIA Nano specific optimisations.
+
+  * Plus hundreds of smaller improvements and tweaks!
+
+  FEATURES
+  * New mpz function: mpz_powm_sec for side-channel quiet modexp
+    computations.
+
+  * New mpn functions: mpn_sqr, mpn_and_n, mpn_ior_n, mpn_xor_n, mpn_nand_n,
+    mpn_nior_n, mpn_xnor_n, mpn_andn_n, mpn_iorn_n, mpn_com, mpn_neg,
+    mpn_copyi, mpn_copyd, mpn_zero.
+
+  * The function mpn_tdiv_qr now allows certain argument overlap.
+
+  * Support for fat binaries for 64-bit x86 processors has been added.
+
+  * A new type, mp_bitcnt_t for bignum bit counts, has been introduced.
+
+  * Support for Windows64 through mingw64 has been added.
+
+  * The cofactors of mpz_gcdext and mpn_gcdext are now more strictly
+    normalised, returning to how GMP 4.2 worked.  (Note that also release
+    4.3.2 has this change.)
+
+  MISC
+  * The mpn_mul function should no longer be used for squaring,
+    instead use the new mpn_sqr.
+
+  * The algorithm selection has been improved, the number of thresholds have
+    more than doubled, and the tuning and use of existing thresholds have
+    been improved.
+
+  * The tune/speed program can measure many of new functions.
+
+  * The mpn_bdivmod function has been removed.  We do not consider this an
+    incompatible change, since the function was marked as preliminary.
+
+  * The testsuite has been enhanced in various ways.

+
+  Speedups:
+  * None.
+
+  Features:
+  * Workarounds for various issues with Mac OS X's build tools.

+  * New sub-quadratic mpn_gcd and mpn_gcdext, as well as improved basecase
+    gcd code.
+  * The multiply FFT code has been slightly improved.

+    in a future GMP release.
+  * Support for the 32-bit ABI under x86-apple-darwin.
+  * x86 CPU recognition code should now default better for future

+
+  Bugs:

+    releases.
+  * C++ bitwise logical operations work for more types.
+  * For C++, gmp.h now includes cstdio, improving compiler compatibility.
+  * Bases > 36 now work properly in mpf_set_str.
+
+  Speedups:
+  * None, except that proper processor recognition helps affected processors.
+
+  Features:
+  * The allocation functions now detect overflow of the mpz_t type.  This means
+    that overflow will now cause an abort, except when the allocation
+    computation itself overflows.  (Such overflow can probably only happen in
+    powering functions; we will detect powering overflow in the future.)
+
+
+Changes between GMP version 4.2.1 and 4.2.2
+
+  * License is now LGPL version 3.

+  * Improved recognition of powerpc systems wrt Altivec/VMX capability.
+  * Misc minor fixes, mainly workarounds for compiler/assembler bugs.
+
+  Speedups:
+  * "Core 2" and Pentium 4 processors, running in 64-bit mode will get a
+     slight boost as they are now specifically recognized.
+
+  Features:
+  * New support for x86_64-solaris

+  * New Mersenne Twister random numbers: gmp_randinit_mt, also now used for
+    gmp_randinit_default.
+  * New random functions: gmp_randinit_set, gmp_urandomb_ui, gmp_urandomm_ui.
+  * New integer functions: mpz_combit, mpz_rootrem.

+  * Conversions mpz_get_d, mpq_get_d, mpf_get_d truncate towards zero,
+    previously their behaviour was unspecified.
+  * Fixes for overflow issues with operands >= 2^31 bits.
+
+  Caveats:
+  * mpfr is gone, and will from now on be released only separately.  Please see
+    www.mpfr.org.

+
+

+
+
+Changes between GMP version 2.0 and 2.0.2
+
+* Many bug fixes.
+
+
+Changes between GMP version 1.3.2 and 2.0
+
+* Division routines in the mpz class have changed.  There are three classes of
+  functions, that rounds the quotient to -infinity, 0, and +infinity,
+  respectively.  The first class of functions have names that begin with
+  mpz_fdiv (f is short for floor), the second class' names begin with mpz_tdiv
+  (t is short for trunc), and the third class' names begin with mpz_cdiv (c is
+  short for ceil).
+
+  The old division routines beginning with mpz_m are similar to the new
+  mpz_fdiv, with the exception that some of the new functions return useful
+  values.
+
+  The old function names can still be used.  All the old functions names will
+  now do floor division, not trunc division as some of them used to.  This was
+  changed to make the functions more compatible with common mathematical
+  practice.
+
+  The mpz_mod and mpz_mod_ui functions now compute the mathematical mod
+  function.  I.e., the sign of the 2nd argument is ignored.
+
+* The mpq assignment functions do not canonicalize their results.  A new
+  function, mpq_canonicalize must be called by the user if the result is not
+  known to be canonical.
+* The mpn functions are now documented.  These functions are intended for
+  very time critical applications, or applications that need full control over
+  memory allocation.  Note that the mpn interface is irregular and hard to
+  use.
+* New functions for arbitrary precision floating point arithmetic.  Names
+  begin with `mpf_'.  Associated type mpf_t.
+* New and improved mpz functions, including much faster GCD, fast exact
+  division (mpz_divexact), bit scan (mpz_scan0 and mpz_scan1), and number
+  theoretical functions like Jacobi (mpz_jacobi) and multiplicative inverse
+  (mpz_invert).
+* New variable types (mpz_t and mpq_t) are available that makes syntax of
+  mpz and mpq calls nicer (no need for & before variables).  The MP_INT and
+  MP_RAT types are still available for compatibility.
+* Uses GNU configure.  This makes it possible to choose target architecture
+  and CPU variant, and to compile into a separate object directory.
+* Carefully optimized assembly for important inner loops.  Support for DEC
+  Alpha, Amd 29000, HPPA 1.0 and 1.1, Intel Pentium and generic x86, Intel
+  i960, Motorola MC68000, MC68020, MC88100, and MC88110, Motorola/IBM
+  PowerPC, National NS32000, IBM POWER, MIPS R3000, R4000, SPARCv7,
+  SuperSPARC, generic SPARCv8, and DEC VAX.  Some support also for ARM,
+  Clipper, IBM ROMP (RT), and Pyramid AP/XP.
+* Faster.  Thanks to the assembler code, new algorithms, and general tuning.
+  In particular, the speed on machines without GCC is improved.
+* Support for machines without alloca.
+* Now under the LGPL.
+
+INCOMPATIBILITIES BETWEEN GMP 1 AND GMP 2
+
+* mpq assignment functions do not canonicalize their results.
+* mpz division functions round differently.
+* mpz mod functions now really compute mod.
+* mpz_powm and mpz_powm_ui now really use mod for reduction.

+
+			THE GNU MP LIBRARY
+
+
+GNU MP is a library for arbitrary precision arithmetic, operating on signed
+integers, rational numbers, and floating point numbers.  It has a rich set of
+functions, and the functions have a regular interface.
+
+GNU MP is designed to be as fast as possible, both for small operands and huge
+operands.  The speed is achieved by using fullwords as the basic arithmetic
+type, by using fast algorithms, with carefully optimized assembly code for the
+most common inner loops for lots of CPUs, and by a general emphasis on speed
+(instead of simplicity or elegance).
+
+GNU MP is believed to be faster than any other similar library.  Its advantage
+increases with operand sizes for certain operations, since GNU MP in many
+cases has asymptotically faster algorithms.
+
+GNU MP is free software and may be freely copied on the terms contained in the
+files COPYING* (see the manual for information on which license(s) applies to
+which components of GNU MP).
+
+
+
+			OVERVIEW OF GNU MP
+
+There are four classes of functions in GNU MP.
+
+ 1. Signed integer arithmetic functions (mpz).  These functions are intended
+    to be easy to use, with their regular interface.  The associated type is
+    `mpz_t'.
+
+ 2. Rational arithmetic functions (mpq).  For now, just a small set of
+    functions necessary for basic rational arithmetics.  The associated type
+    is `mpq_t'.
+
+ 3. Floating-point arithmetic functions (mpf).  If the C type `double'
+    doesn't give enough precision for your application, declare your
+    variables as `mpf_t' instead, set the precision to any number desired,
+    and call the functions in the mpf class for the arithmetic operations.
+
+ 4. Positive-integer, hard-to-use, very low overhead functions are in the
+    mpn class.  No memory management is performed.  The caller must ensure
+    enough space is available for the results.  The set of functions is not
+    regular, nor is the calling interface.  These functions accept input
+    arguments in the form of pairs consisting of a pointer to the least
+    significant word, and an integral size telling how many limbs (= words)
+    the pointer points to.
+
+    Almost all calculations, in the entire package, are made by calling these
+    low-level functions.
+
+For more information on how to use GNU MP, please refer to the documentation.
+It is composed from the file doc/gmp.texi, and can be displayed on the screen
+or printed.  How to do that, as well how to build the library, is described in
+the INSTALL file in this directory.
+
+
+
+			REPORTING BUGS
+
+If you find a bug in the library, please make sure to tell us about it!
+
+You should first check the GNU MP web pages at https://gmplib.org/, under
+"Status of the current release".  There will be patches for all known serious
+bugs there.
+
+Report bugs to gmp-bugs@gmplib.org.  What information is needed in a useful bug
+report is described in the manual.  The same address can be used for suggesting
+modifications and enhancements.

+dnl
+dnl  A cross-"ar" may be necessary when cross-compiling since the build
+dnl  system "ar" might try to interpret the object files to build a symbol
+dnl  table index, hence the use of AC_CHECK_TOOL.
+dnl
+dnl  A user-selected $AR is always left unchanged.  AC_CHECK_TOOL is still
+dnl  run to get the "checking" message printed though.
+dnl
+dnl  If extra flags are added to AR, then ac_cv_prog_AR and
+dnl  ac_cv_prog_ac_ct_AR are set too, since libtool (cvs 2003-03-31 at
+dnl  least) will do an AC_CHECK_TOOL and that will AR from one of those two
+dnl  cached variables.  (ac_cv_prog_AR is used if there's an ac_tool_prefix,
+dnl  or ac_cv_prog_ac_ct_AR is used otherwise.)  FIXME: This is highly
+dnl  dependent on autoconf internals, perhaps it'd work to put our extra
+dnl  flags into AR_FLAGS instead.
+dnl
+dnl  $AR_FLAGS is set to "cq" rather than leaving it to libtool "cru".  The
+dnl  latter fails when libtool goes into piecewise mode and is unlucky
+dnl  enough to have two same-named objects in separate pieces, as happens
+dnl  for instance to random.o (and others) on vax-dec-ultrix4.5.  Naturally
+dnl  a user-selected $AR_FLAGS is left unchanged.
+dnl
+dnl  For reference, $ARFLAGS is used by automake (1.8) for its ".a" archive
+dnl  file rules.  This doesn't get used by the piecewise linking, so we
+dnl  leave it at the default "cru".
+dnl

+dnl
+dnl  This test is designed to be run repeatedly with different cc+cflags
+dnl  selections, so the result is not cached.
+dnl
+dnl  For a native build, meaning $cross_compiling == no, we require that the
+dnl  generated program will run.  This is the same as AC_PROG_CC does in
+dnl  _AC_COMPILER_EXEEXT_WORKS, and checking here will ensure we don't pass
+dnl  a CC/CFLAGS combination that it rejects.
+dnl
+dnl  sparc-*-solaris2.7 can compile ABI=64 but won't run it if the kernel
+dnl  was booted in 32-bit mode.  The effect of requiring the compiler output
+dnl  will run is that a plain native "./configure" falls back on ABI=32, but
+dnl  ABI=64 is still available as a cross-compile.
+dnl
+dnl  The various specific problems we try to detect are done in separate
+dnl  compiles.  Although this is probably a bit slower than one test
+dnl  program, it makes it easy to indicate the problem in AC_MSG_RESULT,
+dnl  hence giving the user a clue about why we rejected the compiler.

+dnl  fxsave/fxrestor in a context switch (to save xmm registers).
+dnl
+dnl  If build!=host, we can fallback on:
+dnl
+dnl      - FreeBSD version 4 is the first supporting xmm.
+dnl
+dnl      - Linux kernel 2.4 might be the first stable series supporting xmm
+dnl        (not sure).  But there's no version number in the GNU/Linux
+dnl        config tuple to test anyway.
+dnl
+dnl  The default is to allow xmm.  This might seem rash, but it's likely
+dnl  most systems know xmm by now, so this will normally be what's wanted.
+dnl  And cross compiling is a bit hairy anyway, so hopefully anyone doing it
+dnl  will be smart enough to know what to do.
+dnl

+dnl  sequence is used (for xorps %xmm0, %xmm0) to make us independent of

+dnl  Currently this is only needed for mingw (and cygwin perhaps) and so is

+dnl
+dnl  On MINGW, recent versions of the linker have an automatic import scheme

+dnl  __declspec (__dllimport__) on the prototype.  It seems functions
+dnl  without type information are treated as data, or something, and calls
+dnl  to them from the mainline will crash.  gcc puts type information on the
+dnl  C functions it generates, we need to do the same for assembler
+dnl  functions.
+dnl
+dnl  This applies only to functions without __declspec(__dllimport__),
+dnl  ie. without __GMP_DECLSPEC in the case of libgmp, so it also works just
+dnl  to ensure all assembler functions used from outside libgmp have
+dnl  __GMP_DECLSPEC on their prototypes.  But this isn't an ideal situation,
+dnl  since we don't want perfectly valid calls going wrong just because
+dnl  there wasn't a prototype in scope.

+dnl      $  - alpha (gas and OSF system assembler)
+dnl      L$ - hppa (gas and HP-UX system assembler)
+dnl
+dnl  The default is "L" if the tests fail for any reason.  There's a good
+dnl  chance this will be adequate, since on most systems labels are local
+dnl  anyway unless given a ".globl", and an "L" will avoid clashes with
+dnl  other identifers.
+dnl
+dnl  For gas, ".L" is normally purely local to the assembler, it doesn't get
+dnl  put into the object file at all.  This style is preferred, to keep the
+dnl  object files nice and clean.
+dnl
+dnl  BSD format nm produces a line like
+dnl
+dnl      00000000 t Lgurkmacka
+dnl
+dnl  The symbol code is normally "t" for text, but any lower case letter
+dnl  indicates a local definition.
+dnl
+dnl  Code "n" is for a debugging symbol, OSF "nm -B" gives that as an upper
+dnl  case "N" for a local.
+dnl
+dnl  HP-UX nm prints an error message (though seems to give a 0 exit) if
+dnl  there's no symbols at all in an object file, hence the use of "dummy".

+dnl
+dnl    SVR4      - the standard is _GLOBAL_OFFSET_TABLE_
+dnl    GNU/Linux - follows SVR4
+dnl    OpenBSD   - an a.out underscore system, uses __GLOBAL_OFFSET_TABLE_
+dnl    NetBSD    - also an a.out underscore system, but _GLOBAL_OFFSET_TABLE_
+dnl
+dnl  The test attempts to link a program using _GLOBAL_OFFSET_TABLE_ or
+dnl  __GLOBAL_OFFSET_TABLE_ to see which works.
+dnl
+dnl  $lt_prog_compiler_pic is included in the compile because old versions
+dnl  of gas wouldn't accept PIC idioms without the right option (-K).  This
+dnl  is the same as what libtool and mpn/Makeasm.am will do.
+dnl
+dnl  $lt_prog_compiler_pic is also included in the link because OpenBSD ld
+dnl  won't accept an R_386_GOTPC relocation without the right options.  This
+dnl  is not what's done by the Makefiles when building executables, but
+dnl  let's hope it's ok (it works fine with gcc).
+dnl
+dnl  The fallback is no additional underscore, on the basis that this will
+dnl  suit SVR4/ELF style systems, which should be much more common than
+dnl  a.out systems with shared libraries.
+dnl
+dnl  Note that it's not an error for the tests to fail, since for instance
+dnl  cygwin, mingw and djgpp don't have a _GLOBAL_OFFSET_TABLE_ scheme at
+dnl  all.
+dnl
+dnl  Perhaps $CCAS could be asked to do the linking as well as the
+dnl  assembling, but in the Makefiles it's only used for assembling, so lets
+dnl  keep it that way.
+dnl
+dnl  The test here is run even under --disable-shared, so that PIC objects
+dnl  can be built and tested by the tune/many.pl development scheme.  The
+dnl  tests will be reasonably quick and won't give a fatal error, so this
+dnl  arrangement is ok.  AC_LIBTOOL_PROG_COMPILER_PIC does its

+dnl
+dnl  An instruction
+dnl
+dnl          addl  $_GLOBAL_OFFSET_TABLE_, %eax
+dnl
+dnl  is incorrectly assembled by gas 2.12 (or thereabouts) and earlier.  It
+dnl  puts an addend 2 into the R_386_GOTPC relocation, but it should be 1
+dnl  for this %eax form being a 1 byte opcode (with other registers it's 2
+dnl  opcode bytes).  See note about this in mpn/x86/README too.
+dnl
+dnl  We assemble this, surrounded by some unlikely byte sequences as
+dnl  delimiters, and check for the bad output.
+dnl
+dnl  This is for use by compiler probing in GMP_PROG_CC_WORKS, so the result
+dnl  is not cached.
+dnl
+dnl  This test is not specific to gas, but old gas is the only assembler we
+dnl  know of with this problem.  The Solaris has been seen coming out ok.
+dnl
+dnl  ".text" is hard coded because this macro is wanted before GMP_ASM_TEXT.
+dnl  This should be fine, ".text" is normal on x86 systems, and certainly
+dnl  will be fine with the offending gas.
+dnl
+dnl  If an error occurs when assembling, we consider the assembler ok, since
+dnl  the bad output does not occur.  This happens for instance on mingw,
+dnl  where _GLOBAL_OFFSET_TABLE_ results in a bfd error, since there's no
+dnl  GOT etc in PE object files.
+dnl
+dnl  This test is used before the object file extension has been determined,
+dnl  so we force output to conftest.o.  Using -o with -c is not portable,
+dnl  but we think all x86 compilers will accept -o with -c, certainly gcc
+dnl  does.
+dnl
+dnl  -fPIC is hard coded here, because this test is for use before libtool
+dnl  has established the pic options.  It's right for gcc, but perhaps not

+dnl
+dnl  A dummy function is compiled and the ".s" output examined.  The pattern
+dnl  matching might be a bit fragile, but should work at least with gcc on
+dnl  sensible systems.  Certainly it's better than hard coding a table of
+dnl  conventions.
+dnl
+dnl  For non-PIC, any ".data" is taken to mean a counter might be passed.
+dnl  It's assumed a movl will set it up, and the right register is taken
+dnl  from that movl.  Any movl involving %esp is ignored (a frame pointer
+dnl  setup normally).
+dnl
+dnl  For PIC, any ".data" is similarly interpreted, but a GOTOFF identifies
+dnl  the line setting up the right register.
+dnl
+dnl  In both cases a line with "mcount" identifies the call and that line is
+dnl  used literally.
+dnl
+dnl  On some systems (eg. FreeBSD 3.5) gcc emits ".data" but doesn't use it,
+dnl  so it's not an error to have .data but then not find a register.
+dnl
+dnl  Variations in mcount conventions on different x86 systems can be found
+dnl  in gcc config/i386.  mcount can have a "_" prefix or be .mcount or
+dnl  _mcount_ptr, and for PIC it can be called through a GOT entry, or via
+dnl  the PLT.  If a pointer to a counter is required it's passed in %eax or
+dnl  %edx.
+dnl
+dnl  Flags to specify PIC are taken from $lt_prog_compiler_pic set by
+dnl  AC_PROG_LIBTOOL.
+dnl

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+/* __GMP_DECLSPEC supports Windows DLL versions of libgmp, and is empty in
+   all other circumstances.
+
+   When compiling objects for libgmp, __GMP_DECLSPEC is an export directive,
+   or when compiling for an application it's an import directive.  The two
+   cases are differentiated by __GMP_WITHIN_GMP defined by the GMP Makefiles
+   (and not defined from an application).
+
+   __GMP_DECLSPEC_XX is similarly used for libgmpxx.  __GMP_WITHIN_GMPXX
+   indicates when building libgmpxx, and in that case libgmpxx functions are
+   exports, but libgmp functions which might get called are imports.
+
+   Libtool DLL_EXPORT define is not used.
+
+   There's no attempt to support GMP built both static and DLL.  Doing so
+   would mean applications would have to tell us which of the two is going
+   to be used when linking, and that seems very tedious and error prone if
+   using GMP by hand, and equally tedious from a package since autoconf and
+   automake don't give much help.
+
+   __GMP_DECLSPEC is required on all documented global functions and
+   variables, the various internals in gmp-impl.h etc can be left unadorned.
+   But internals used by the test programs or speed measuring programs
+   should have __GMP_DECLSPEC, and certainly constants or variables must
+   have it or the wrong address will be resolved.
+
+   In gcc __declspec can go at either the start or end of a prototype.
+
+   In Microsoft C __declspec must go at the start, or after the type like
+   void __declspec(...) *foo()".  There's no __dllexport or anything to
+   guard against someone foolish #defining dllexport.  _export used to be
+   available, but no longer.
+
+   In Borland C _export still exists, but needs to go after the type, like
+   "void _export foo();".  Would have to change the __GMP_DECLSPEC syntax to
+   make use of that.  Probably more trouble than it's worth.  */

+   read-modify-write on CISC CPUs.
+
+   Alternatives:
+
+   Using a pair of pointers instead of indexing would be possible, but gcc
+   isn't able to recognise compile-time src==dst in that case, even when the
+   pointers are incremented more or less together.  Other compilers would
+   very likely have similar difficulty.
+
+   gcc could use "if (__builtin_constant_p(src==dst) && src==dst)" or
+   similar to detect a compile-time src==dst.  This works nicely on gcc
+   2.95.x, it's not good on gcc 3.0 where __builtin_constant_p(p==p) seems
+   to be always false, for a pointer p.  But the current code form seems
+   good enough for src==dst anyway.
+
+   gcc on x86 as usual doesn't give particularly good flags handling for the
+   carry/borrow detection.  It's tempting to want some multi instruction asm
+   blocks to help it, and this was tried, but in truth there's only a few
+   instructions to save and any gain is all too easily lost by register
+   juggling setting up for the asm.  */

+/* __GMP_DECLSPEC supports Windows DLL versions of libgmp, and is empty in
+   all other circumstances.
+
+   When compiling objects for libgmp, __GMP_DECLSPEC is an export directive,
+   or when compiling for an application it's an import directive.  The two
+   cases are differentiated by __GMP_WITHIN_GMP defined by the GMP Makefiles
+   (and not defined from an application).
+
+   __GMP_DECLSPEC_XX is similarly used for libgmpxx.  __GMP_WITHIN_GMPXX
+   indicates when building libgmpxx, and in that case libgmpxx functions are
+   exports, but libgmp functions which might get called are imports.
+
+   Libtool DLL_EXPORT define is not used.
+
+   There's no attempt to support GMP built both static and DLL.  Doing so
+   would mean applications would have to tell us which of the two is going
+   to be used when linking, and that seems very tedious and error prone if
+   using GMP by hand, and equally tedious from a package since autoconf and
+   automake don't give much help.
+
+   __GMP_DECLSPEC is required on all documented global functions and
+   variables, the various internals in gmp-impl.h etc can be left unadorned.
+   But internals used by the test programs or speed measuring programs
+   should have __GMP_DECLSPEC, and certainly constants or variables must
+   have it or the wrong address will be resolved.
+
+   In gcc __declspec can go at either the start or end of a prototype.
+
+   In Microsoft C __declspec must go at the start, or after the type like
+   void __declspec(...) *foo()".  There's no __dllexport or anything to
+   guard against someone foolish #defining dllexport.  _export used to be
+   available, but no longer.
+
+   In Borland C _export still exists, but needs to go after the type, like
+   "void _export foo();".  Would have to change the __GMP_DECLSPEC syntax to
+   make use of that.  Probably more trouble than it's worth.  */

+
+   Alternatives:
+

+   isn't able to recognise compile-time src==dst in that case, even when the

+

+   2.95.x, it's not good on gcc 3.0 where __builtin_constant_p(p==p) seems
+   to be always false, for a pointer p.  But the current code form seems
+   good enough for src==dst anyway.
+
+   gcc on x86 as usual doesn't give particularly good flags handling for the
+   carry/borrow detection.  It's tempting to want some multi instruction asm
+   blocks to help it, and this was tried, but in truth there's only a few
+   instructions to save and any gain is all too easily lost by register

+
+   When compiling objects for libgmp, __GMP_DECLSPEC is an export directive,
+   or when compiling for an application it's an import directive.  The two
+   cases are differentiated by __GMP_WITHIN_GMP defined by the GMP Makefiles
+   (and not defined from an application).
+
+   __GMP_DECLSPEC_XX is similarly used for libgmpxx.  __GMP_WITHIN_GMPXX
+   indicates when building libgmpxx, and in that case libgmpxx functions are
+   exports, but libgmp functions which might get called are imports.
+
+   Libtool DLL_EXPORT define is not used.
+
+   There's no attempt to support GMP built both static and DLL.  Doing so
+   would mean applications would have to tell us which of the two is going
+   to be used when linking, and that seems very tedious and error prone if
+   using GMP by hand, and equally tedious from a package since autoconf and
+   automake don't give much help.
+
+   __GMP_DECLSPEC is required on all documented global functions and
+   variables, the various internals in gmp-impl.h etc can be left unadorned.
+   But internals used by the test programs or speed measuring programs
+   should have __GMP_DECLSPEC, and certainly constants or variables must
+   have it or the wrong address will be resolved.
+
+   In gcc __declspec can go at either the start or end of a prototype.
+
+   In Microsoft C __declspec must go at the start, or after the type like
+   void __declspec(...) *foo()".  There's no __dllexport or anything to
+   guard against someone foolish #defining dllexport.  _export used to be
+   available, but no longer.
+
+   In Borland C _export still exists, but needs to go after the type, like
+   "void _export foo();".  Would have to change the __GMP_DECLSPEC syntax to
+   make use of that.  Probably more trouble than it's worth.  */

+   disappear, and the load/add/store gets a chance to become a
+   read-modify-write on CISC CPUs.
+
+   Alternatives:
+
+   Using a pair of pointers instead of indexing would be possible, but gcc
+   isn't able to recognise compile-time src==dst in that case, even when the
+   pointers are incremented more or less together.  Other compilers would
+   very likely have similar difficulty.
+
+   gcc could use "if (__builtin_constant_p(src==dst) && src==dst)" or
+   similar to detect a compile-time src==dst.  This works nicely on gcc
+   2.95.x, it's not good on gcc 3.0 where __builtin_constant_p(p==p) seems
+   to be always false, for a pointer p.  But the current code form seems
+   good enough for src==dst anyway.
+
+   gcc on x86 as usual doesn't give particularly good flags handling for the
+   carry/borrow detection.  It's tempting to want some multi instruction asm
+   blocks to help it, and this was tried, but in truth there's only a few
+   instructions to save and any gain is all too easily lost by register
+   juggling setting up for the asm.  */

+\`configure' configures GNU MP 6.2.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>

+  YFLAGS      The list of arguments that will be passed by default to $YACC.

+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# supports, and/or what the user selects.  Naturally the mpn assembler code
+# selected is very dependent on the ABI.
+#
+# The closest the standard tools come to a notion of ABI is something like
+# "sparc64" which encodes a CPU and an ABI together.  This doesn't seem to
+# scale well for GMP, where exact CPU types like "ultrasparc2" are wanted,
+# separate from the ABI used on them.
+#
+#
+# The variables set here are
+#
+#   cclist              the compiler choices
+#   xx_cflags           flags for compiler xx
+#   xx_cflags_maybe     flags for compiler xx, if they work
+#   xx_cppflags         cpp flags for compiler xx
+#   xx_cflags_optlist   list of sets of optional flags
+#   xx_cflags_yyy       set yyy of optional flags for compiler xx
+#   xx_ldflags          -Wc,-foo flags for libtool linking with compiler xx
+#   ar_flags            extra flags for $AR
+#   nm_flags            extra flags for $NM
+#   limb                limb size, can be "longlong"
+#   path                mpn search path
+#   extra_functions     extra mpn functions
+#   fat_path            fat binary mpn search path [if fat binary desired]
+#   fat_functions       fat functions
+#   fat_thresholds      fat thresholds
+#
+# Suppose xx_cflags_optlist="arch", then flags from $xx_cflags_arch are
+# tried, and the first flag that works will be used.  An optlist like "arch
+# cpu optimize" can be used to get multiple independent sets of flags tried.
+# The first that works from each will be used.  If no flag in a set works
+# then nothing from that set is added.
+#
+# For multiple ABIs, the scheme extends as follows.
+#
+#   abilist               set of ABI choices
+#   cclist_aa             compiler choices in ABI aa
+#   xx_aa_cflags          flags for xx in ABI aa
+#   xx_aa_cflags_maybe    flags for xx in ABI aa, if they work
+#   xx_aa_cppflags        cpp flags for xx in ABI aa
+#   xx_aa_cflags_optlist  list of sets of optional flags in ABI aa
+#   xx_aa_cflags_yyy      set yyy of optional flags for compiler xx in ABI aa
+#   xx_aa_ldflags         -Wc,-foo flags for libtool linking
+#   ar_aa_flags           extra flags for $AR in ABI aa
+#   nm_aa_flags           extra flags for $NM in ABI aa
+#   limb_aa               limb size in ABI aa, can be "longlong"
+#   path_aa               mpn search path in ABI aa
+#   extra_functions_aa    extra mpn functions in ABI aa
+#
+# As a convenience, the unadorned xx_cflags (etc) are used for the last ABI
+# in ablist, if an xx_aa_cflags for that ABI isn't given.  For example if
+# abilist="64 32" then $cc_64_cflags will be used for the 64-bit ABI, but
+# for the 32-bit either $cc_32_cflags or $cc_cflags is used, whichever is
+# defined.  This makes it easy to add some 64-bit compilers and flags to an
+# unadorned 32-bit set.
+#
+# limb=longlong (or limb_aa=longlong) applies to all compilers within that
+# ABI.  It won't work to have some needing long long and some not, since a
+# single instantiated gmp.h will be used by both.
+#
+# SPEED_CYCLECOUNTER, cyclecounter_size and CALLING_CONVENTIONS_OBJS are
+# also set here, with an ABI suffix.
+#
+#
+#
+# A table-driven approach like this to mapping cpu type to good compiler
+# options is a bit of a maintenance burden, but there's not much uniformity
+# between options specifications on different compilers.  Some sort of
+# separately updatable tool might be cute.
+#
+# The use of lots of variables like this, direct and indirect, tends to
+# obscure when and how various things are done, but unfortunately it's
+# pretty much the only way.  If shell subroutines were portable then actual
+# code like "if this .. do that" could be written, but attempting the same
+# with full copies of GMP_PROG_CC_WORKS etc expanded at every point would
+# hugely bloat the output.

+# Table of compilers, options, and mpn paths.  This code has various related
+# purposes
+#
+#   - better default CC/CFLAGS selections than autoconf otherwise gives
+#   - default CC/CFLAGS selections for extra CPU types specific to GMP
+#   - a few tests for known bad compilers
+#   - choice of ABIs on suitable systems
+#   - selection of corresponding mpn search path
+#
+# After GMP specific searches and tests, the standard autoconf AC_PROG_CC is
+# called.  User selections of CC etc are respected.
+#
+# Care is taken not to use macros like AC_TRY_COMPILE during the GMP
+# pre-testing, since they of course depend on AC_PROG_CC, and also some of
+# them cache their results, which is not wanted.
+#
+# The ABI selection mechanism is unique to GMP.  All that reaches autoconf
+# is a different selection of CC/CFLAGS according to the best ABI the system
+# supports, and/or what the user selects.  Naturally the mpn assembler code
+# selected is very dependent on the ABI.
+#
+# The closest the standard tools come to a notion of ABI is something like
+# "sparc64" which encodes a CPU and an ABI together.  This doesn't seem to
+# scale well for GMP, where exact CPU types like "ultrasparc2" are wanted,
+# separate from the ABI used on them.
+#

+# The first that works from each will be used.  If no flag in a set works
+# then nothing from that set is added.

+# For multiple ABIs, the scheme extends as follows.

+#
+# As a convenience, the unadorned xx_cflags (etc) are used for the last ABI
+# in ablist, if an xx_aa_cflags for that ABI isn't given.  For example if
+# abilist="64 32" then $cc_64_cflags will be used for the 64-bit ABI, but
+# for the 32-bit either $cc_32_cflags or $cc_cflags is used, whichever is
+# defined.  This makes it easy to add some 64-bit compilers and flags to an
+# unadorned 32-bit set.
+#
+# limb=longlong (or limb_aa=longlong) applies to all compilers within that

+                   DEMONSTRATION CALCULATOR PROGRAM
+
+
+This is a simple program, meant only to show one way to use GMP with yacc
+and lex to make a calculator.  Usage and comments on the implementation can
+be found in calc.y.
+
+Within a GMP build tree, the generated Makefile can be used to build the
+program,
+
+	make calc
+
+(or on a DOS system, "make calc.exe").
+
+Elsewhere, once GMP has been installed, the program can be compiled with for
+instance
+
+	gcc calc.c calclex.c -lgmp -o calc
+
+Or if GNU readline is used then
+
+	gcc calc.c calclex.c calcread.c -lgmp -lreadline -o calc
+
+(again, on a DOS system "-o calc.exe").
+
+Readline support can be enabled or disabled in calc-config.h.  That file is
+created by the GMP ./configure based on the --with-readline option.  The
+default is --with-readline=detect, which means to use readline if available.
+"yes" can be used to force it to be used, or "no" to not use it.
+
+The supplied calc.c was generated by GNU bison, but a standard yacc should
+work too.
+
+The supplied calclex.c was generated by GNU flex, but a standard lex should
+work too.  The readline support may or may not work with a standard lex (see
+comments with input() in calcread.c).  Note also that a standard lex will
+require its library "-ll" on the compile command line.  "./configure" sets
+this up in the GMP build tree Makefile.

+/* This is a simple program, meant only to show one way to use GMP for this
+   sort of thing.  There's few features, and error checking is minimal.
+   Standard input is read, calc_help() below shows the inputs accepted.
+
+   Expressions are evaluated as they're read.  If user defined functions
+   were wanted it'd be necessary to build a parse tree like pexpr.c does, or
+   a list of operations for a stack based evaluator.  That would also make
+   it possible to detect and optimize evaluations "mod m" like pexpr.c does.
+
+   A stack is used for intermediate values in the expression evaluation,
+   separate from the yacc parser stack.  This is simple, makes error
+   recovery easy, minimizes the junk around mpz calls in the rules, and
+   saves initializing or clearing "mpz_t"s during a calculation.  A
+   disadvantage though is that variables must be copied to the stack to be
+   worked on.  A more sophisticated calculator or language system might be
+   able to avoid that when executing a compiled or semi-compiled form.
+
+   Avoiding repeated initializing and clearing of "mpz_t"s is important.  In
+   this program the time spent parsing is obviously much greater than any
+   possible saving from this, but a proper calculator or language should
+   take some trouble over it.  Don't be surprised if an init/clear takes 3
+   or more times as long as a 10 limb addition, depending on the system (see
+   the mpz_init_realloc_clear example in tune/README).  */

+/* This is a simple program, meant only to show one way to use GMP for this
+   sort of thing.  There's few features, and error checking is minimal.
+   Standard input is read, calc_help() below shows the inputs accepted.
+
+   Expressions are evaluated as they're read.  If user defined functions
+   were wanted it'd be necessary to build a parse tree like pexpr.c does, or
+   a list of operations for a stack based evaluator.  That would also make
+   it possible to detect and optimize evaluations "mod m" like pexpr.c does.
+
+   A stack is used for intermediate values in the expression evaluation,
+   separate from the yacc parser stack.  This is simple, makes error
+   recovery easy, minimizes the junk around mpz calls in the rules, and
+   saves initializing or clearing "mpz_t"s during a calculation.  A
+   disadvantage though is that variables must be copied to the stack to be
+   worked on.  A more sophisticated calculator or language system might be
+   able to avoid that when executing a compiled or semi-compiled form.
+
+   Avoiding repeated initializing and clearing of "mpz_t"s is important.  In
+   this program the time spent parsing is obviously much greater than any
+   possible saving from this, but a proper calculator or language should
+   take some trouble over it.  Don't be surprised if an init/clear takes 3
+   or more times as long as a 10 limb addition, depending on the system (see
+   the mpz_init_realloc_clear example in tune/README).  */

+                    GMP EXPRESSION EVALUATION
+                    -------------------------
+
+
+
+THIS CODE IS PRELIMINARY AND MAY BE SUBJECT TO INCOMPATIBLE CHANGES IN
+FUTURE VERSIONS OF GMP.
+
+
+
+The files in this directory implement a simple scheme of string based
+expression parsing and evaluation, supporting mpz, mpq and mpf.
+
+This will be slower than direct GMP library calls, but may be convenient in
+various circumstances, such as while prototyping, or for letting a user
+enter values in symbolic form.  "2**5723-7" for example is a lot easier to
+enter or maintain than the equivalent written out in decimal.
+
+
+
+BUILDING
+
+Nothing in this directory is a normal part of libgmp, and nothing is built
+or installed, but various Makefile rules are available to compile
+everything.
+
+All the functions are available through a little library (there's no shared
+library since upward binary compatibility is not guaranteed).
+
+	make libexpr.a
+
+In a program, prototypes are available using
+
+	#include "expr.h"
+
+run-expr.c is a sample program doing evaluations from the command line.
+
+	make run-expr
+	./run-expr '1+2*3'
+
+t-expr.c is self-test program, it prints nothing if successful.
+
+	make t-expr
+	./t-expr
+
+The expr*.c sources don't depend on gmp-impl.h and can be compiled with just
+a standard installed GMP.  This isn't true of t-expr though, since it uses
+some of the internal tests/libtests.la.
+
+
+
+SIMPLE USAGE
+
+int mpz_expr (mpz_t res, int base, const char *e, ...);
+int mpq_expr (mpq_t res, int base, const char *e, ...);
+int mpf_expr (mpf_t res, int base, const char *e, ...);
+
+These functions evaluate simple arithmetic expressions.  For example,
+
+	mpz_expr (result, 0, "123+456", NULL);
+
+Numbers are parsed by mpz_expr and mpq_expr the same as mpz_set_str with the
+given base.  mpf_expr follows mpf_set_str, but supporting an "0x" prefix for
+hex when base==0.
+
+	mpz_expr (result, 0, "0xAAAA * 0x5555", NULL);
+
+White space, as indicated by <ctype.h> isspace(), is ignored except for the
+purpose of separating tokens.
+
+Variables can be included in expressions by putting them in the stdarg list
+after the string.  "a", "b", "c" etc in the expression string designate
+those values.  For example,
+
+        mpq_t  foo, bar;
+        ...
+	mpq_expr (q, 10, "2/3 + 1/a + b/2", foo, bar, NULL);
+
+Here "a" will be the value from foo and "b" from bar.  Up to 26 variables
+can be included this way.  The NULL must be present to indicate the end of
+the list.
+
+Variables can also be written "$a", "$b" etc.  This is necessary when using
+bases greater than 10 since plain "a", "b" etc will otherwise be interpreted
+as numbers.  For example,
+
+        mpf_t  quux;
+        mpf_expr (f, 16, "F00F@-6 * $a", quux, NULL);
+
+All the standard C operators are available, with the usual precedences, plus
+"**" for exponentiation at the highest precedence (and right associative).
+
+        Operators      Precedence
+         **              220
+         ~ ! - (unary)   210
+         * / %           200
+         + -             190
+         << >>           180
+         <= < >= >       170
+         == !=           160
+         &               150
+         ^               140
+         |               130
+         &&              120
+         ||              110
+         ? :             100/101
+
+Currently only mpz_expr has the bitwise ~ % & ^ and | operators.  The
+precedence numbers are of interest in the advanced usage described below.
+
+Various functions are available too.  For example,
+
+        mpz_expr (res, 10, "gcd(123,456,789) * abs(a)", var, NULL);
+
+The following is the full set of functions,
+
+        mpz_expr
+            abs bin clrbit cmp cmpabs congruent_p divisible_p even_p fib fac
+            gcd hamdist invert jacobi kronecker lcm lucnum max min nextprime
+            odd_p perfect_power_p perfect_square_p popcount powm
+            probab_prime_p root scan0 scan1 setbit sgn sqrt
+
+        mpq_expr
+            abs, cmp, den, max, min, num, sgn
+
+        mpf_expr
+            abs, ceil, cmp, eq, floor, integer_p, max, min, reldiff, sgn,
+            sqrt, trunc
+
+All these are the same as the GMP library functions, except that min and max
+don't exist in the library.  Note also that min, max, gcd and lcm take any
+number of arguments, not just two.
+
+mpf_expr does all calculations to the precision of the destination variable.
+
+
+Expression parsing can succeed or fail.  The return value indicates this,
+and will be one of the following
+
+	MPEXPR_RESULT_OK
+	MPEXPR_RESULT_BAD_VARIABLE
+	MPEXPR_RESULT_BAD_TABLE
+	MPEXPR_RESULT_PARSE_ERROR
+	MPEXPR_RESULT_NOT_UI
+
+BAD_VARIABLE is when a variable is referenced that hasn't been provided.
+For example if "c" is used when only two parameters have been passed.
+BAD_TABLE is applicable to the advanced usage described below.
+
+PARSE_ERROR is a general syntax error, returned for any mal-formed input
+string.
+
+NOT_UI is returned when an attempt is made to use an operand that's bigger
+than an "unsigned long" with a function that's restricted to that range.
+For example "fib" is mpz_fib_ui and only accepts an "unsigned long".
+
+
+
+
+ADVANCED USAGE
+
+int mpz_expr_a (const struct mpexpr_operator_t *table,
+                mpz_ptr res, int base, const char *e, size_t elen,
+                mpz_srcptr var[26])
+int mpq_expr_a (const struct mpexpr_operator_t *table,
+                mpq_ptr res, int base, const char *e, size_t elen,
+                mpq_srcptr var[26])
+int mpf_expr_a (const struct mpexpr_operator_t *table,
+                mpf_ptr res, int base, unsigned long prec,
+                const char *e, size_t elen,
+                mpf_srcptr var[26])
+
+These functions are an advanced interface to expression parsing.
+
+The string is taken as pointer and length.  This makes it possible to parse
+an expression in the middle of somewhere without copying and null
+terminating it.
+
+Variables are an array of 26 pointers to the appropriate operands, or NULL
+for variables that are not available.  Any combination of variables can be
+given, for example just "x" and "y" (var[23] and var[24]) could be set.
+
+Operators and functions are specified with a table.  This makes it possible
+to provide additional operators or functions, or to completely change the
+syntax.  The standard tables used by the simple functions above are
+available as
+
+	const struct mpexpr_operator_t * const mpz_expr_standard_table;
+	const struct mpexpr_operator_t * const mpq_expr_standard_table;
+	const struct mpexpr_operator_t * const mpf_expr_standard_table;
+
+struct mpexpr_operator_t is the following
+
+	struct mpexpr_operator_t {
+	  const char    *name;
+	  mpexpr_fun_t  fun;
+	  int           type;
+	  int           precedence;
+	};
+
+        typedef void (*mpexpr_fun_t) (void);
+
+As an example, the standard mpz_expr table entry for multiplication is as
+follows.  See the source code for the full set of standard entries.
+
+	{ "*", (mpexpr_fun_t) mpz_mul, MPEXPR_TYPE_BINARY, 200 },
+
+"name" is the string to parse, "fun" is the function to call for it, "type"
+indicates what parameters the function takes (among other things), and
+"precedence" sets its operator precedence.
+
+A NULL for "name" indicates the end of the table, so for example an mpf
+table with nothing but addition could be
+
+        struct mpexpr_operator_t  table[] = {
+          { "+", (mpexpr_fun_t) mpf_add, MPEXPR_TYPE_BINARY, 190 },
+          { NULL }
+        };
+
+A special type MPEXPR_TYPE_NEW_TABLE makes it possible to chain from one
+table to another.  For example the following would add a "mod" operator to
+the standard mpz table,
+
+        struct mpexpr_operator_t  table[] = {
+        { "mod", (mpexpr_fun_t) mpz_fdiv_r, MPEXPR_TYPE_BINARY, 125 },
+        { (const char *) mpz_expr_standard_table, NULL, MPEXPR_TYPE_NEW_TABLE }
+        };
+
+Notice the low precedence on "mod", so that for instance "45+26 mod 7"
+parses as "(45+26)mod7".
+
+
+Functions are designated by a precedence of 0.  They always occur as
+"foo(expr)" and so have no need for a precedence level.  mpq_abs in the
+standard mpq table is
+
+	{ "abs", (mpexpr_fun_t) mpq_abs, MPEXPR_TYPE_UNARY },
+
+Functions expecting no arguments as in "foo()" can be given with
+MPEXPR_TYPE_0ARY, or actual constants to be parsed as just "foo" are
+MPEXPR_TYPE_CONSTANT.  For example if a "void mpf_const_pi(mpf_t f)"
+function existed (which it doesn't) it could be,
+
+	{ "pi", (mpexpr_fun_t) mpf_const_pi, MPEXPR_TYPE_CONSTANT },
+
+
+Parsing of operator names is done by seeking the table entry with the
+longest matching name.  So for instance operators "<" and "<=" exist, and
+when presented with "x <= y" the parser matches "<=" because it's longer.
+
+Parsing of function names, on the other hand, is done by requiring a whole
+alphanumeric word to match.  For example presented with "fib2zz(5)" the
+parser will attempt to find a function called "fib2zz".  A function "fib"
+wouldn't be used because it doesn't match the whole word.
+
+The flag MPEXPR_TYPE_WHOLEWORD can be ORed into an operator type to override
+the default parsing style.  Similarly MPEXPR_TYPE_OPERATOR into a function.
+
+
+Binary operators are left associative by default, meaning they're evaluated
+from left to right, so for example "1+2+3" is treated as "(1+2)+3".
+MPEXPR_TYPE_RIGHTASSOC can be ORed into the operator type to work from right
+to left as in "1+(2+3)".  This is generally what's wanted for
+exponentiation, and for example the standard mpz table has
+
+        { "**", (mpexpr_fun_t) mpz_pow_ui,
+          MPEXPR_TYPE_BINARY_UI | MPEXPR_TYPE_RIGHTASSOC, 220 }
+
+Unary operators are postfix by default.  For example a factorial to be used
+as "123!" might be
+
+	{ "!", (mpexpr_fun_t) mpz_fac_ui, MPEXPR_TYPE_UNARY_UI, 215 }
+
+MPEXPR_TYPE_PREFIX can be ORed into the type to get a prefix operator.  For
+instance negation (unary minus) in the standard mpf table is
+
+	{ "-", (mpexpr_fun_t) mpf_neg,
+          MPEXPR_TYPE_UNARY | MPEXPR_TYPE_PREFIX, 210 },
+
+
+The same operator can exist as a prefix unary and a binary, or as a prefix
+and postfix unary, simply by putting two entries in the table.  While
+parsing the context determines which style is sought.  But note that the
+same operator can't be both a postfix unary and a binary, since the parser
+doesn't try to look ahead to decide which ought to be used.
+
+When there's two entries for an operator, both prefix or both postfix (or
+binary), then the first in the table will be used.  This makes it possible
+to override an entry in a standard table, for example to change the function
+it calls, or perhaps its precedence level.  The following would change mpz
+division from tdiv to cdiv,
+
+        struct mpexpr_operator_t  table[] = {
+          { "/", (mpexpr_fun_t) mpz_cdiv_q, MPEXPR_TYPE_BINARY, 200 },
+          { "%", (mpexpr_fun_t) mpz_cdiv_r, MPEXPR_TYPE_BINARY, 200 },
+          { (char *) mpz_expr_standard_table, NULL, MPEXPR_TYPE_NEW_TABLE }
+        };
+
+
+The type field indicates what parameters the given function expects.  The
+following styles of functions are supported.  mpz_t is shown, but of course
+this is mpq_t for mpq_expr_a, mpf_t for mpf_expr_a, etc.
+
+    MPEXPR_TYPE_CONSTANT     void func (mpz_t result);
+
+    MPEXPR_TYPE_0ARY         void func (mpz_t result);
+    MPEXPR_TYPE_I_0ARY       int func (void);
+
+    MPEXPR_TYPE_UNARY        void func (mpz_t result, mpz_t op);
+    MPEXPR_TYPE_UNARY_UI     void func (mpz_t result, unsigned long op);
+    MPEXPR_TYPE_I_UNARY      int func (mpz_t op);
+    MPEXPR_TYPE_I_UNARY_UI   int func (unsigned long op);
+
+    MPEXPR_TYPE_BINARY       void func (mpz_t result, mpz_t op1, mpz_t op2);
+    MPEXPR_TYPE_BINARY_UI    void func (mpz_t result,
+                                        mpz_t op1, unsigned long op2);
+    MPEXPR_TYPE_I_BINARY     int func (mpz_t op1, mpz_t op2);
+    MPEXPR_TYPE_I_BINARY_UI  int func (mpz_t op1, unsigned long op2);
+
+    MPEXPR_TYPE_TERNARY      void func (mpz_t result,
+                                        mpz_t op1, mpz_t op2, mpz_t op3);
+    MPEXPR_TYPE_TERNARY_UI   void func (mpz_t result, mpz_t op1, mpz_t op2,
+                                        unsigned long op3);
+    MPEXPR_TYPE_I_TERNARY    int func (mpz_t op1, mpz_t op2, mpz_t op3);
+    MPEXPR_TYPE_I_TERNARY_UI int func (mpz_t op1, mpz_t op2,
+                                       unsigned long op3);
+
+Notice the pattern of "UI" for the last parameter as an unsigned long, or
+"I" for the result as an "int" return value.
+
+It's important that the declared type for an operator or function matches
+the function pointer given.  Any mismatch will have unpredictable results.
+
+For binary functions, a further type attribute is MPEXPR_TYPE_PAIRWISE which
+indicates that any number of arguments should be accepted, and evaluated by
+applying the given binary function to them pairwise.  This is used by gcd,
+lcm, min and max.  For example the standard mpz gcd is
+
+	{ "gcd", (mpexpr_fun_t) mpz_gcd,
+	  MPEXPR_TYPE_BINARY | MPEXPR_TYPE_PAIRWISE },
+
+Some special types exist for comparison operators (or functions).
+MPEXPR_TYPE_CMP_LT through MPEXPR_TYPE_CMP_GE expect an MPEXPR_TYPE_I_BINARY
+function, returning positive, negative or zero like mpz_cmp and similar.
+For example the standard mpf "!=" operator is
+
+	{ "!=", (mpexpr_fun_t) mpf_cmp, MPEXPR_TYPE_CMP_NE, 160 },
+
+But there's no obligation to use these types, for instance the standard mpq
+table just uses a plain MPEXPR_TYPE_I_BINARY and mpq_equal for "==".
+
+Further special types MPEXPR_TYPE_MIN and MPEXPR_TYPE_MAX exist to implement
+the min and max functions, and they take a function like mpf_cmp similarly.
+The standard mpf max function is
+
+	{ "max",  (mpexpr_fun_t) mpf_cmp,
+          MPEXPR_TYPE_MAX | MPEXPR_TYPE_PAIRWISE },
+
+These can be used as operators too, for instance the following would be the
+>? operator which is a feature of GNU C++,
+
+	{ ">?", (mpexpr_fun_t) mpf_cmp, MPEXPR_TYPE_MAX, 175 },
+
+Other special types are used to define "(" ")" parentheses, "," function
+argument separator, "!" through "||" logical booleans, ternary "?"  ":", and
+the "$" which introduces variables.  See the sources for how they should be
+used.
+
+
+User definable operator tables will have various uses.  For example,
+
+  - a subset of the C operators, to be rid of infrequently used things
+  - a more mathematical syntax like "." for multiply, "^" for powering,
+    and "!" for factorial
+  - a boolean evaluator with "^" for AND, "v" for OR
+  - variables introduced with "%" instead of "$"
+  - brackets as "[" and "]" instead of "(" and ")"
+
+The only fixed parts of the parsing are the treatment of numbers, whitespace
+and the two styles of operator/function name recognition.
+
+As a final example, the following would be a complete mpz table implementing
+some operators with a more mathematical syntax.  Notice there's no need to
+preserve the standard precedence values, anything can be used so long as
+they're in the desired relation to each other.  There's also no need to have
+entries in precedence order, but it's convenient to do so to show what comes
+where.
+
+        static const struct mpexpr_operator_t  table[] = {
+	  { "^",   (mpexpr_fun_t) mpz_pow_ui,
+            MPEXPR_TYPE_BINARY_UI | MPEXPR_TYPE_RIGHTASSOC,           9 },
+
+          { "!",   (mpexpr_fun_t) mpz_fac_ui, MPEXPR_TYPE_UNARY_UI,   8 },
+          { "-",   (mpexpr_fun_t) mpz_neg,
+            MPEXPR_TYPE_UNARY | MPEXPR_TYPE_PREFIX,                   7 },
+
+          { "*",   (mpexpr_fun_t) mpz_mul,    MPEXPR_TYPE_BINARY,     6 },
+          { "/",   (mpexpr_fun_t) mpz_fdiv_q, MPEXPR_TYPE_BINARY,     6 },
+
+          { "+",   (mpexpr_fun_t) mpz_add,    MPEXPR_TYPE_BINARY,     5 },
+          { "-",   (mpexpr_fun_t) mpz_sub,    MPEXPR_TYPE_BINARY,     5 },
+
+          { "mod", (mpexpr_fun_t) mpz_mod,    MPEXPR_TYPE_BINARY,     6 },
+
+          { ")",   NULL,                      MPEXPR_TYPE_CLOSEPAREN, 4 },
+          { "(",   NULL,                      MPEXPR_TYPE_OPENPAREN,  3 },
+          { ",",   NULL,                      MPEXPR_TYPE_ARGSEP,     2 },
+
+          { "$",   NULL,                      MPEXPR_TYPE_VARIABLE,   1 },
+          { NULL }
+        };
+
+
+
+
+INTERNALS
+
+Operator precedence is implemented using a control and data stack, there's
+no C recursion.  When an expression like 1+2*3 is read the "+" is held on
+the control stack and 1 on the data stack until "*" has been parsed and
+applied to 2 and 3.  This happens any time a higher precedence operator
+follows a lower one, or when a right-associative operator like "**" is
+repeated.
+
+Parentheses are handled by making "(" a special prefix unary with a low
+precedence so a whole following expression is read.  The special operator
+")" knows to discard the pending "(".  Function arguments are handled
+similarly, with the function pretending to be a low precedence prefix unary
+operator, and with "," allowed within functions.  The same special ")"
+operator recognises a pending function and will invoke it appropriately.
+
+The ternary "? :" operator is also handled using precedences.  ":" is one
+level higher than "?", so when a valid a?b:c is parsed the ":" finds a "?"
+on the control stack.  It's a parse error for ":" to find anything else.
+
+
+
+FUTURE
+
+The ternary "?:" operator evaluates the "false" side of its pair, which is
+wasteful, though it ought to be harmless.  It'd be better if it could
+evaluate only the "true" side.  Similarly for the logical booleans "&&" and
+"||" if they know their result already.
+
+Functions like MPEXPR_TYPE_BINARY could return a status indicating operand
+out of range or whatever, to get an error back through mpz_expr etc.  That
+would want to be just an option, since plain mpz_add etc have no such
+return.
+
+Could have assignments like "a = b*c" modifying the input variables.
+Assignment could be an operator attribute, making it expect an lvalue.
+There would want to be a standard table without assignments available
+though, so user input could be safely parsed.
+
+The closing parenthesis table entry could specify the type of open paren it
+expects, so that "(" and ")" could match and "[" and "]" match but not a
+mixture of the two.  Currently "[" and "]" can be added, but there's no
+error on writing a mixed expression like "2*(3+4]".  Maybe also there could
+be a way to say that functions can only be written with one or the other
+style of parens.

+
+   Evaluate each argument as a simple expression.  By default this is in mpz
+   integers, but -q selects mpq or -f selects mpf.  For mpf the float
+   precision can be set with -p.  In all cases the input base can be set
+   with -b, or the default is "0" meaning decimal with "0x" allowed.
+
+   This is a pretty trivial program, it's just an easy way to experiment
+   with the evaluation functions.  */

+=head1 NAME
+
+GMP - Perl interface to the GNU Multiple Precision Arithmetic Library
+
+=head1 SYNOPSIS
+
+    use GMP;
+    use GMP::Mpz;
+    use GMP::Mpq;
+    use GMP::Mpf;
+    use GMP::Rand;
+
+=head1 DESCRIPTION
+
+This module provides access to GNU MP arbitrary precision integers,
+rationals and floating point.
+
+No functions are exported from these packages by default, but can be
+selected in the usual way, or the tag :all for everything.
+
+    use GMP::Mpz qw(gcd, lcm);   # just these functions
+    use GMP::Mpq qw(:all);       # everything in mpq
+
+=head2 GMP::Mpz
+
+This class provides arbitrary precision integers.  A new mpz can be
+constructed with C<mpz>.  The initial value can be an integer, float,
+string, mpz, mpq or mpf.  Floats, mpq and mpf will be automatically
+truncated to an integer.
+
+    use GMP::Mpz qw(:all);
+    my $a = mpz(123);
+    my $b = mpz("0xFFFF");
+    my $c = mpz(1.5);       # truncated
+
+The following overloaded operators are available, and corresponding
+assignment forms like C<+=>,
+
+=over 4
+
+=item
+
++ - * / % E<lt>E<lt> E<gt>E<gt> ** & | ^ ! E<lt> E<lt>= == != E<gt> E<gt>=
+E<lt>=E<gt> abs not sqrt
+
+=back
+
+C</> and C<%> round towards zero (as per the C<tdiv> functions in GMP).
+
+The following functions are available, behaving the same as the
+corresponding GMP mpz functions,
+
+=over 4
+
+=item
+
+bin, cdiv, cdiv_2exp, clrbit, combit, congruent_p, congruent_2exp_p,
+divexact, divisible_p, divisible_2exp_p, even_p, fac, fdiv, fdiv_2exp, fib,
+fib2, gcd, gcdext, hamdist, invert, jacobi, kronecker, lcm, lucnum, lucnum2,
+mod, mpz_export, mpz_import, nextprime, odd_p, perfect_power_p,
+perfect_square_p, popcount, powm, probab_prime_p, realloc, remove, root,
+roote, scan0, scan1, setbit, sizeinbase, sqrtrem, tdiv, tdiv_2exp, tstbit
+
+=back
+
+C<cdiv>, C<fdiv> and C<tdiv> and their C<2exp> variants return a
+quotient/remainder pair.  C<fib2> returns a pair F[n] and F[n-1], similarly
+C<lucnum2>.  C<gcd> and C<lcm> accept a variable number of arguments (one or
+more).  C<gcdext> returns a triplet of gcd and two cofactors, for example
+
+    use GMP::Mpz qw(:all);
+    $a = 7257;
+    $b = 10701;
+    ($g, $x, $y) = gcdext ($a, $b);
+    print "gcd($a,$b) is $g, and $g == $a*$x + $b*$y\n";
+
+C<mpz_import> and C<mpz_export> are so named to avoid the C<import> keyword.
+Their parameters are as follows,
+
+    $z = mpz_import ($order, $size, $endian, $nails, $string);
+    $string = mpz_export ($order, $size, $endian, $nails, $z);
+
+The order, size, endian and nails parameters are as per the corresponding C
+functions.  The string input for C<mpz_import> is interpreted as byte data
+and must be a multiple of $size bytes.  C<mpz_export> conversely returns a
+string of byte data, which will be a multiple of $size bytes.
+
+C<invert> returns the inverse, or undef if it doesn't exist.  C<remove>
+returns a remainder/multiplicity pair.  C<root> returns the nth root, and
+C<roote> returns a root/bool pair, the bool indicating whether the root is
+exact.  C<sqrtrem> and C<rootrem> return a root/remainder pair.
+
+C<clrbit>, C<combit> and C<setbit> expect a variable which they can modify,
+it doesn't make sense to pass a literal constant.  Only the given variable
+is modified, if other variables are referencing the same mpz object then a
+new copy is made of it.  If the variable isn't an mpz it will be coerced to
+one.  For instance,
+
+    use GMP::Mpz qw(setbit);
+    setbit (123, 0);  # wrong, don't pass a constant
+    $a = mpz(6);
+    $b = $a;
+    setbit ($a, 0);   # $a becomes 7, $b stays at 6
+
+C<scan0> and C<scan1> return ~0 if no 0 or 1 bit respectively is found.
+
+=head2 GMP::Mpq
+
+This class provides rationals with arbitrary precision numerators and
+denominators.  A new mpq can be constructed with C<mpq>.  The initial value
+can be an integer, float, string, mpz, mpq or mpf, or a pair of integers or
+mpz's.  No precision is lost when converting a float or mpf, the exact value
+is retained.
+
+    use GMP::Mpq qw(:all);
+    $a = mpq();              # zero
+    $b = mpq(0.5);           # gives 1/2
+    $b = mpq(14);            # integer 14
+    $b = mpq(3,4);           # fraction 3/4
+    $b = mpq("7/12");        # fraction 7/12
+    $b = mpq("0xFF/0x100");  # fraction 255/256
+
+When a fraction is given, it should be in the canonical form specified in
+the GMP manual, which is denominator positive, no common factors, and zero
+always represented as 0/1.  If not then C<canonicalize> can be called to put
+it in that form.  For example,
+
+    use GMP::Mpq qw(:all);
+    $q = mpq(21,15);   # eek! common factor 3
+    canonicalize($q);  # get rid of it
+
+The following overloaded operators are available, and corresponding
+assignment forms like C<+=>,
+
+=over 4
+
+=item
+
++ - * / E<lt>E<lt> E<gt>E<gt> ** ! E<lt> E<lt>= == != E<gt> E<gt>=
+E<lt>=E<gt> abs not
+
+=back
+
+The following functions are available,
+
+=over 4
+
+=item
+
+den, inv, num
+
+=back
+
+C<inv> calculates 1/q, as per the corresponding GMP function.  C<num> and
+C<den> return an mpz copy of the numerator or denominator respectively.  In
+the future C<num> and C<den> might give lvalues so the original mpq can be
+modified through them, but this is not done currently.
+
+=head2 GMP::Mpf
+
+This class provides arbitrary precision floating point numbers.  The
+mantissa is an arbitrary user-selected precision and the exponent is a fixed
+size (one machine word).
+
+A new mpf can be constructed with C<mpf>.  The initial value can be an
+integer, float, string, mpz, mpq or mpf.  The second argument specifies the
+desired precision in bits, or if omitted then the default precision is used.
+
+    use GMP::Mpf qw(:all);
+    $a = mpf();         # zero
+    $b = mpf(-7.5);     # default precision
+    $c = mpf(1.5, 500); # 500 bits precision
+    $d = mpf("1.0000000000000001");
+
+The following overloaded operators are available, with the corresponding
+assignment forms like C<+=>,
+
+=over 4
+
+=item
+
++ - * / E<lt>E<lt> E<gt>E<gt> ** ! E<lt> E<lt>= == != E<gt> E<gt>=
+E<lt>=E<gt> abs not sqrt
+
+=back
+
+The following functions are available, behaving the same as the
+corresponding GMP mpf functions,
+
+=over 4
+
+=item
+
+ceil, floor, get_default_prec, get_prec, mpf_eq, set_default_prec, set_prec,
+trunc
+
+=back
+
+C<mpf_eq> is so named to avoid clashing with the perl C<eq> operator.
+
+C<set_prec> expects a variable which it can modify, it doesn't make sense to
+pass a literal constant.  Only the given variable is modified, if other
+variables are referencing the same mpf object then a new copy is made of it.
+If the variable isn't an mpf it will be coerced to one.
+
+Results are the same precision as inputs, or if two mpf's are given to a
+binary operator then the precision of the first is used.  For example,
+
+    use GMP::Mpf qw(mpf);
+    $a = mpf(2.0, 100);
+    $b = mpf(2.0, 500);
+    $c = $a + $b;         # gives 100 bits precision
+
+Mpf to string conversion via "" or the usual string contexts uses C<$#> the
+same as normal float to string conversions, or defaults to C<%.g> if C<$#>
+is not defined.  C<%.g> means all significant digits in the selected
+precision.
+
+=head2 GMP class
+
+The following functions are available in the GMP class,
+
+=over 4
+
+=item
+
+fits_slong_p, get_d, get_d_2exp, get_si, get_str, integer_p, printf, sgn,
+sprintf, version
+
+=back
+
+C<get_d_2exp> accepts any integer, string, float, mpz, mpq or mpf operands
+and returns a float and an integer exponent,
+
+    ($dbl, $exp) = get_d_2exp (mpf ("3.0"));
+    # dbl is 0.75, exp is 2
+
+C<get_str> takes an optional second argument which is the base, defaulting
+to decimal.  A negative base means upper case, as per the C functions.  For
+integer, integer string, mpz or mpq operands a string is returned.
+
+    use GMP qw(:all);
+    use GMP::Mpq qw(:all);
+    print get_str(mpq(-5,8)),"\n";      # -5/8
+    print get_str(255,16),"\n";         # ff
+
+For float, float strings or mpf operands, C<get_str> accepts an optional
+third parameter being how many digits to produce, defaulting to 0 which
+means all digits.  (Only as many digits as can be accurately represented by
+the float precision are ever produced though.)  A string/exponent pair is
+returned, as per the C mpf_get_str function.  For example,
+
+    use GMP qw(:all);
+    use GMP::Mpf qw(:all);
+    ($s, $e) = get_str(111.111111111, 10, 4);
+    printf ".$se$e\n";                  # .1111e3
+    ($s, $e) = get_str(1.625, 10);
+    print "0.$s*10^$e\n";               # 0.1625*10^1
+    ($s, $e) = get_str(mpf(2)**20, 16);
+    printf ".%s@%x\n", $s, $e;          # .1@14
+
+C<printf> and C<sprintf> allow formatted output of GMP types.  mpz and mpq
+values can be used with integer conversions (d, o, x, X) and mpf with float
+conversions (f, e, E, g, G).  All the standard perl printf features are
+available too.  For example,
+
+    use GMP::Mpz qw(mpz);
+    use GMP::Mpf qw(mpf);
+    GMP::printf ("%d %d %s", 123, mpz(2)**128, 'foo');
+    GMP::printf STDERR "%.40f", mpf(1.234);
+
+In perl 5.6.1 it doesn't seem to work to export C<printf>, the plain builtin
+C<printf> is reached unless calls are C<&printf()> style.  Explicit use of
+C<GMP::printf> is suggested.  C<sprintf> doesn't suffer this problem.
+
+    use GMP qw(sprintf);
+    use GMP::Mpq qw(mpq);
+    $s = sprintf "%x", mpq(15,16);
+
+C<version> is not exported by default or by tag :all, calling it as
+C<GMP::version()> is recommended.  It returns the GMP library version
+string, which is not to be confused with the module version number.
+
+The other GMP module functions behave as per the corresponding GMP routines,
+and accept any integer, string, float, mpz, mpq or mpf.  For example,
+
+    use GMP qw(:all);
+    use GMP::Mpz qw(mpz);
+    $z = mpz(123);
+    print sgn($z);    # gives 1
+
+Because each of GMP::Mpz, GMP::Mpq and GMP::Mpf is a sub-class of GMP,
+C<-E<gt>> style calls work too.
+
+    use GMP qw(:all);
+    use GMP::Mpq qw(mpf);
+    $q = mpq(-5,7);
+    if ($q->integer_p())   # false
+      ...
+
+=head2 GMP::Rand
+
+This class provides objects holding an algorithm and state for random number
+generation.  C<randstate> creates a new object, for example,
+
+    use GMP::Rand qw(randstate);
+    $r = randstate();
+    $r = randstate('lc_2exp_size', 64);
+    $r = randstate('lc_2exp', 43840821, 1, 32);
+    $r = randstate('mt');
+    $r = randstate($another_r);
+
+With no parameters this corresponds to the C function
+C<gmp_randinit_default>, and is a compromise between speed and randomness.
+'lc_2exp_size' corresponds to C<gmp_randinit_lc_2exp_size>, 'lc_2exp'
+corresponds to C<gmp_randinit_lc_2exp>, and 'mt' corresponds to
+C<gmp_randinit_mt>.  Or when passed another randstate object, a copy of that
+object is made.
+
+'lc_2exp_size' can fail if the requested size is bigger than the internal
+table provides for, in which case undef is returned.  The maximum size
+currently supported is 128.  The other forms always succeed.
+
+A randstate can be seeded with an integer or mpz, using the C<seed> method.
+/dev/random might be a good source of randomness, or time() or
+Time::HiRes::time() might be adequate, depending on the application.
+
+    $r->seed(time()));
+
+Random numbers can be generated with the following functions,
+
+=over 4
+
+=item
+
+mpf_urandomb, mpz_rrandomb, mpz_urandomb, mpz_urandomm,
+gmp_urandomb_ui, gmp_urandomm_ui
+
+=back
+
+Each constructs a new mpz or mpf and with a distribution per the
+corresponding GMP function.  For example,
+
+    use GMP::Rand (:all);
+    $r = randstate();
+    $a = mpz_urandomb($r,256);         # uniform mpz, 256 bits
+    $b = mpz_urandomm($r,mpz(3)**100); # uniform mpz, 0 to 3**100-1
+    $c = mpz_rrandomb($r,1024);        # special mpz, 1024 bits
+    $f = mpf_urandomb($r,128);         # uniform mpf, 128 bits, 0<=$f<1
+    $f = gmp_urandomm_ui($r,56);       # uniform int, 0 to 55
+
+=head2 Coercion
+
+Arguments to operators and functions are converted as necessary to the
+appropriate type.  For instance C<**> requires an unsigned integer exponent,
+and an mpq argument will be converted, so long as it's an integer in the
+appropriate range.
+
+    use GMP::Mpz (mpz);
+    use GMP::Mpq (mpq);
+    $p = mpz(3) ** mpq(45);   # allowed, 45 is an integer
+
+It's an error if a conversion to an integer or mpz would cause any
+truncation.  For example,
+
+    use GMP::Mpz (mpz);
+    $p = mpz(3) + 1.25;       # not allowed
+    $p = mpz(3) + mpz(1.25);  # allowed, explicit truncation
+
+Comparisons, however, accept any combination of operands and are always done
+exactly.  For example,
+
+    use GMP::Mpz (mpz);
+    print mpz(3) < 3.1;       # true
+
+Variables used on the left of an assignment operator like C<+=> are subject
+to coercion too.  An integer, float or string will change type when an mpz,
+mpq or mpf is applied to it.  For example,
+
+    use GMP::Mpz (mpz);
+    $a = 1;
+    $a += mpz(1234);   # $a becomes an mpz
+
+=head2 Overloading
+
+The rule for binary operators in the C<overload> mechanism is that if both
+operands are class objects then the method from the first is used.  This
+determines the result type when mixing GMP classes.  For example,
+
+    use GMP::Mpz (mpz);
+    use GMP::Mpq (mpq);
+    use GMP::Mpf (mpf);
+    $z = mpz(123);
+    $q = mpq(3,2);
+    $f = mpf(1.375)
+    print $q+$f;     # gives an mpq
+    print $f+$z;     # gives an mpf
+    print $z+$f;     # not allowed, would lose precision
+
+=head2 Constants
+
+A special tag C<:constants> is recognised in the module exports list.  It
+doesn't select any functions, but indicates that perl constants should be
+GMP objects.  This can only be used on one of GMP::Mpz, GMP::Mpq or GMP::Mpf
+at any one time, since they apply different rules.
+
+GMP::Mpz will treat constants as mpz's if they're integers, or ordinary
+floats if not.  For example,
+
+    use GMP::Mpz qw(:constants);
+    print 764861287634126387126378128,"\n";   # an mpz
+    print 1.25,"\n";                          # a float
+
+GMP::Mpq is similar, treating integers as mpq's and leaving floats to the
+normal perl handling.  Something like 3/4 is read as two integer mpq's and a
+division, but that's fine since it gives the intended fraction.
+
+    use GMP::Mpq qw(:constants);
+    print 3/4,"\n";    # an mpq
+    print 1.25,"\n";   # a float
+
+GMP::Mpf will treat all constants as mpf's using the default precision.
+BEGIN blocks can be used to set that precision while the code is parsed.
+For example,
+
+    use GMP::Mpf qw(:constants);
+    BEGIN { GMP::Mpf::set_default_prec(256); }
+    print 1/3;
+    BEGIN { GMP::Mpf::set_default_prec(64); }
+    print 5/7;
+
+A similar special tag :noconstants is recognised to turn off the constants
+feature.  For example,
+
+    use GMP::Mpz qw(:constants);
+    print 438249738748174928193,"\n";   # an mpz
+    use GMP::Mpz qw(:noconstants);
+    print 438249738748174928193,"\n";   # now a float
+
+All three 'integer', 'binary' and 'float' constant methods are captured.
+'float' is captured even for GMP::Mpz and GMP::Mpq since perl by default
+treats integer strings as floats if they don't fit a plain integer.
+

+GMP manual, L<perl>, L<overload>.
+
+=head1 BUGS
+
+In perl 5.005_03 on i386 FreeBSD, the overloaded constants sometimes provoke
+seg faults.  Don't know if that's a perl bug or a GMP module bug, though it
+does seem to go bad before reaching anything in GMP.xs.
+
+There's no way to specify an arbitrary base when converting a string to an
+mpz (or mpq or mpf), only hex or octal with 0x or 0 (for mpz and mpq, but
+not for mpf).
+
+These modules are not reentrant or thread safe, due to the implementation of
+the XSUBs.
+
+Returning a new object from the various functions is convenient, but
+assignment versions could avoid creating new objects.  Perhaps they could be
+named after the C language functions, eg. mpq_inv($q,$q);
+
+It'd be good if C<num> and C<den> gave lvalues so the underlying mpq could
+be manipulated.
+
+C<printf> could usefully accept %b for mpz, mpq and mpf, and perhaps %x for
+mpf too.
+
+C<get_str> returning different style values for integer versus float is a
+bit unfortunate.  With mpz, mpq and mpf objects there's no doubt what it
+will do, but on a plain scalar its action depends on whether the scalar was
+promoted to a float at any stage, and then on the GMP module rules about
+using the integer or float part.
+
+=head1 INTERNALS
+
+In usual perl object style, an mpz is a reference to an object blessed into
+class C<GMP::Mpz>.  The object holds a pointer to the C language C<mpz_t>
+structure.  Similarly for mpq, mpf and randstate.
+
+A free list of mpz and mpq values is kept to avoid repeated initializing and
+clearing when objects are created and destroyed.  This aims to help speed,
+but it's not clear whether it's really needed.
+
+mpf doesn't use a free list because the precision of new objects can be
+different each time.
+
+No interface to C<mpf_set_prec_raw> is provided.  It wouldn't be very useful
+since there's no way to make an operation store its result in a particular
+object.  The plain C<set_prec> is useful though, for truncating to a lower
+precision, or as a sort of directive that subsequent calculations involving
+that variable should use a higher precision.
+
+The overheads of perl dynamic typing (operator dispatch, operand type
+checking or coercion) will mean this interface is slower than using C
+directly.
+
+Some assertion checking is available as a compile-time option.

+/* Notes:
+
+   Routines are grouped with the alias feature and a table of function
+   pointers where possible, since each xsub routine ends up with quite a bit
+   of code size.  Different combinations of arguments and return values have
+   to be separate though.
+
+   The "INTERFACE:" feature isn't available in perl 5.005 and so isn't used.
+   "ALIAS:" requires a table lookup with CvXSUBANY(cv).any_i32 (which is
+   "ix") whereas "INTERFACE:" would have CvXSUBANY(cv).any_dptr as the
+   function pointer immediately.
+
+   Mixed-type swapped-order assignments like "$a = 123; $a += mpz(456);"
+   invoke the plain overloaded "+", not "+=", which makes life easier.
+
+   mpz_assume etc types are used with the overloaded operators since such
+   operators are always called with a class object as the first argument, we
+   don't need an sv_derived_from() lookup to check.  There's assert()s in
+   MPX_ASSUME() for this though.
+
+   The overload_constant routines reached via overload::constant get 4
+   arguments in perl 5.6, not the 3 as documented.  This is apparently a
+   bug, using "..." lets us ignore the extra one.
+
+   There's only a few "si" functions in gmp, so usually SvIV values get
+   handled with an mpz_set_si into a temporary and then a full precision mpz
+   routine.  This is reasonably efficient.
+
+   Argument types are checked, with a view to preserving all bits in the
+   operand.  Perl is a bit looser in its arithmetic, allowing rounding or
+   truncation to an intended operand type (IV, UV or NV).
+
+   Bugs:
+
+   The memory leak detection attempted in GMP::END() doesn't work when mpz's
+   are created as constants because END() is called before they're
+   destroyed.  What's the right place to hook such a check?
+
+   See the bugs section of GMP.pm too.  */

+/* mg_get is called every time we get a value, even if the private flags are
+   still set from a previous such call.  This is the same as as SvIV and
+   friends do.
+
+   When POK, we use the PV, even if there's an IV or NV available.  This is
+   because it's hard to be sure there wasn't any rounding in establishing
+   the IV and/or NV.  Cases of overflow, where the PV should definitely be
+   used, are easy enough to spot, but rounding is hard.  So although IV or
+   NV would be more efficient, we must use the PV to be sure of getting all
+   the data.  Applications should convert once to mpz, mpq or mpf when using
+   a value repeatedly.
+
+   Zany dual-type scalars like $! where the IV is an error code and the PV
+   is an error description string won't work with this preference for PV,
+   but that's too bad.  Such scalars should be rare, and unlikely to be used
+   in bignum calculations.
+
+   When IOK and NOK are both set, we would prefer to use the IV since it can
+   be converted more efficiently, and because on a 64-bit system the NV may
+   have less bits than the IV.  The following rules are applied,
+
+   - If the NV is not an integer, then we must use that NV, since clearly
+     the IV was merely established by rounding and is not the full value.
+
+   - In perl prior to 5.8, an NV too big for an IV leaves an overflow value
+     0xFFFFFFFF.  If the NV is too big to fit an IV then clearly it's the NV
+     which is the true value and must be used.
+
+   - In perl 5.8 and up, such an overflow doesn't set IOK, so that test is
+     unnecessary.  However when coming from get-magic, IOKp _is_ set, and we
+     must check for overflow the same as in older perl.
+
+   FIXME:
+
+   We'd like to call mg_get just once, but unfortunately sv_derived_from()
+   will call it for each of our checks.  We could do a string compare like
+   sv_isa ourselves, but that only tests the exact class, it doesn't
+   recognise subclassing.  There doesn't seem to be a public interface to
+   the subclassing tests (in the internal isa_lookup() function).  */

+                  GMP PERL MODULE INSTALLATION
+
+
+This module can be compiled within the GMP source directory or moved
+elsewhere and compiled.  An installed GMP can be used, or a specified
+GMP build tree.  Both static and shared GMP builds will work.
+
+The simplest case is when GMP has been installed to a standard system
+location
+
+	perl Makefile.PL
+	make
+
+If not yet installed then the top-level GMP build directory must be
+specified
+
+	perl Makefile.PL GMP_BUILDDIR=/my/gmp/build
+	make
+
+In any case, with the module built, the sample program provided can be
+run
+
+	perl -Iblib/arch sample.pl
+
+If you built a shared version of libgmp but haven't yet installed it,
+then it might be necessary to add a run-time path to it.  For example
+
+	LD_LIBRARY_PATH=/my/gmp/build/.libs perl -Iblib/arch sample.pl
+
+Documentation is provided in pod format in GMP.pm, and will have been
+"man"-ified in the module build
+
+	man -l blib/man3/GMP.3pm
+or
+	man -M`pwd`/blib GMP
+
+A test script is provided, running a large number of more or less
+trivial checks
+
+	make test
+
+The module and its documentation can be installed in the usual way
+
+	make install
+
+This will be into /usr/local or wherever the perl Config module
+directs, but that can be controlled back at the Makefile.PL stage with
+the usual ExtUtils::MakeMaker options.
+
+Once installed, programs using the GMP module become simply
+
+	perl sample.pl
+
+And the documentation read directly too
+
+	man GMP

+/* This expressions evaluator works by building an expression tree (using a
+   recursive descent parser) which is then evaluated.  The expression tree is
+   useful since we want to optimize certain expressions (like a^b % c).
+
+   Usage: pexpr [options] expr ...
+   (Assuming you called the executable `pexpr' of course.)
+
+   Command line options:
+
+   -b        print output in binary
+   -o        print output in octal
+   -d        print output in decimal (the default)
+   -x        print output in hexadecimal
+   -b<NUM>   print output in base NUM
+   -t        print timing information
+   -html     output html
+   -wml      output wml
+   -split    split long lines each 80th digit

+/* IDEAS:
+ * Do not fill primes[] with real primes when the range [fr,to] is small,
+   when fr,to are relatively large.  Fill primes[] with odd numbers instead.
+   [Probably a bad idea, since the primes[] array would become very large.]
+ * Separate small primes and large primes when sieving.  Either the Montgomery
+   way (i.e., having a large array a multiple of L1 cache size), or just
+   separate loops for primes <= S and primes > S.  The latter primes do not
+   require an inner loop, since they will touch the sieving array at most once.
+ * Pre-fill sieving array with an appropriately aligned ...00100100... pattern,
+   then omit 3 from primes array.  (May require similar special handling of 3
+   as we now have for 2.)
+ * A large SIEVE_LIMIT currently implies very large memory usage, mainly due
+   to the sieving array in make_primelist, but also because of the primes[]
+   array.  We might want to stage the program, using sieve_region/find_primes
+   to build primes[].  Make report() a function pointer, as part of achieving
+   this.
+ * Store primes[] as two arrays, one array with primes represented as delta
+   values using just 8 bits (if gaps are too big, store bogus primes!)
+   and one array with "rem" values.  The latter needs 32-bit values.
+ * A new entry point, mpz_probab_prime_likely_p, would be useful.
+ * Improve command line syntax and versatility.  "primes -f FROM -t TO",
+   allow either to be omitted for open interval.  (But disallow
+   "primes -c -f FROM" since that would be infinity.)  Allow printing a
+   limited *number* of primes using syntax like "primes -f FROM -n NUMBER".
+ * When looking for maxgaps, we should not perform any primality testing until
+   we find possible record gaps.  Should speed up the searches tremendously.

+/* Usage: qcn [-p limit] <discriminant>...
+
+   A fundamental discriminant means one of the form D or 4*D with D
+   square-free.  Each argument is checked to see it's congruent to 0 or 1
+   mod 4 (as all discriminants must be), and that it's negative, but there's
+   no check on D being square-free.
+
+   This program is a bit of a toy, there are better methods for calculating
+   the class number and class group structure.

+
+* Adding a new file
+
+** Adding a top-level file
+
+  i) Add it to libgmp_la_SOURCES in Makefile.am.
+
+  ii) If libmp.la needs it (usually doesn't), then add it to
+      libmp_la_SOURCES too.
+
+** Adding a subdirectory file
+
+For instance for mpz,
+
+  i) Add file.c to libmpz_la_SOURCES in mpz/Makefile.am.
+
+  ii) Add mpz/file$U.lo to MPZ_OBJECTS in the top-level Makefile.am
+
+  iii) If for some reason libmp.la needs it (usually doesn't) then add
+       mpz/file$U.lo to libmp_la_DEPENDENCIES in the top-level
+       Makefile.am too.
+
+The same applies to mpf, mpq, scanf and printf.
+
+** Adding an mpn file
+
+The way we build libmpn (in the `mpn' subdirectory) is quite special.
+
+Currently only mpn/mp_bases.c is truly generic and included in every
+configuration.  All other files are linked at build time into the mpn
+build directory from one of the CPU specific sub-directories, or from
+the mpn/generic directory.
+
+There are four types of mpn source files.
+
+  .asm	  Assembly code preprocessed with m4
+  .S	  Assembly code preprocessed with cpp
+  .s	  Assembly code not preprocessed at all
+  .c	  C code
+
+There are two types of .asm files.
+
+  i) ``Normal'' files containing one function, though possibly with
+     more than one entry point.
+
+  ii) Multi-function files that generate one of a set of functions
+      according to build options.
+
+To add a new implementation of an existing function,
+
+  i) Put it in the appropriate CPU-specific mpn subdirectory, it'll be
+     detected and used.
+
+  ii) Any entrypoints tested by HAVE_NATIVE_func in other code must
+      have PROLOGUE(func) for configure to grep.  This is normal for
+      .asm or .S files, but for .c files a dummy comment like the
+      following will be needed.
+
+              /*
+              PROLOGUE(func)
+              */
+
+To add a new implementation using a multi-function file, in addition
+do the following,
+
+  i) Use a MULFUNC_PROLOGUE(func1 func2 ...) in the .asm, declaring
+     all the functions implemented, including carry-in variants.
+
+     If there's a separate PROLOGUE(func) for each possible function
+     (but this is usually not the case), then MULFUNC_PROLOGUE isn't
+     necessary.
+
+To add a new style of multi-function file, in addition do the
+following,
+
+  i) Add to the GMP_MULFUNC_CHOICES "case" statement in configure.in
+     which lists each multi-function filename and what function files
+     it can provide.
+
+To add a completely new mpn function file, do the following,
+
+  i) Ensure the filename is a valid C identifier, due to the
+     -DOPERATION_$* used to support multi-function files.  This means
+     "-" can't be used (but "_" can).
+
+  ii) Add it to configure.in under one of the following
+
+      a) `gmp_mpn_functions' if it exists for every target.  This
+         means there must be a C version in mpn/generic.  (Eg. mul_1)
+
+      b) `gmp_mpn_functions_optional' if it's a standard function, but
+         doesn't need to exist for every target.  Code wanting to use
+         this will test HAVE_NATIVE_func to see if it's available.
+         (Eg. copyi)
+
+      c) `extra_functions' for some targets, if it's a special
+         function that only ever needs to exist for certain targets.
+         Code wanting to use it can test either HAVE_NATIVE_func or
+         HAVE_HOST_CPU_foo, as desired.
+
+  iii) If HAVE_NATIVE_func is going to be used, then add a #undef to
+       the AH_VERBATIM([HAVE_NATIVE] block in configure.in.
+
+  iv) If the function can be provided by a multi-function file, then
+      add to the "case" statement in configure.in which lists each
+      multi-function filename and what function files it can provide.
+
+
+** Adding a test program
+
+  i) Tests to be run early in the testing can be added to the main
+     "tests" sub-directory.
+
+  ii) Tests for mpn, mpz, mpq and mpf can be added under the
+      corresponding tests subdirectory.
+
+  iii) Generic tests for late in the testing can be added to
+       "tests/misc".  printf and scanf tests currently live there too.
+
+  iv) Random number function tests can be added to "tests/rand".  That
+      directory has some development-time programs too.
+
+  v) C++ test programs can be added to "tests/cxx".  A line like the
+     following must be added for each, since by default automake looks
+     for a .c file.
+
+             t_foo_SOURCES = t-foo.cc
+
+In all cases the name of the program should be added to check_PROGRAMS
+in the Makefile.am.  TESTS is equal to check_PROGRAMS, so all those
+programs get run.
+
+"tests/devel" has a number of programs which are only for development
+purposes and are not for use in "make check".  These should be listed
+in EXTRA_PROGRAMS to get Makefile rules created, but they're never
+built or run unless an explicit "make someprog" is used.
+
+
+* Adding a new CPU
+
+In general it's policy to use proper names for each CPU type
+supported.  If two CPUs are quite similar and perhaps don't have any
+actual differences in GMP then they're still given separate names, for
+example alphaev67 and alphaev68.
+
+Canonical names:
+
+  i) Decide the canonical CPU names GMP will accept.
+
+  ii) Add these to the config.sub wrapper if configfsf.sub doesn't
+      already accept them.
+
+  iii) Document the names in gmp.texi.
+
+Aliases (optional):
+
+  i) Any aliases can be added to the config.sub wrapper, unless
+     configfsf.sub already does the right thing with them.
+
+  ii) Leave configure.in and everywhere else using only the canonical
+      names.  Aliases shouldn't appear anywhere except config.sub.
+
+  iii) Document in gmp.texi, if desired.  Usually this isn't a good
+       idea, better encourage users to know just the canonical
+       names.
+
+Configure:
+
+  i) Add patterns to configure.in for the new CPU names.  Include the
+     following (see configure.in for the variables to set up),
+
+     a) ABI choices (if any).
+     b) Compiler choices.
+     c) mpn path for CPU specific code.
+     d) Good default CFLAGS for each likely compiler.
+     d) Any special tests necessary on the compiler or assembler
+        capabilities.
+
+  ii) M4 macros to be shared by asm files in a CPU family are by
+      convention in a foo-defs.m4 like mpn/x86/x86-defs.m4.  They're
+      likely to use settings from config.m4 generated by configure.
+
+Fat binaries:
+
+  i) In configure.in, add CPU specific directory(s) to fat_path.
+
+  ii) In mpn/<cpu>/fat.c, identify the CPU at runtime and use suitable
+      CPUVEC_SETUP_subdir macros to select the function pointers for it.
+
+  iii) For the x86s, add to the "$tmp_prefix" setups in configure.in
+       which abbreviates subdirectory names to fit an 8.3 filesystem.
+       (No need to restrict to 8.3, just ensure uniqueness when
+       truncated.)
+
+
+* The configure system
+
+** Installing tools
+
+The current versions of automake, autoconf and libtool in use can be
+checked in the ChangeLog.  Look for "Update to ...".  Patches may have
+been applied, look for "Regenerate ...".
+
+The GMP build system is in places somewhat dependent on the internals
+of the build tools.  Obviously that's avoided as much as possible, but
+where it can't it creates a problem when upgrading or attempting to
+use different tools versions.
+
+** Updating gmp
+
+The following files need to be updated when going to a new version of
+the build tools.  Unfortunately the tools generally don't identify
+when an out-of-date version is present.
+
+aclocal.m4 is updated by running "aclocal".  (Only needed for a new
+automake or libtool.)
+
+INSTALL.autoconf can be copied from INSTALL in autoconf.
+
+ltmain.sh comes from libtool.  Remove it and run "libtoolize --copy",
+or just copy the file by hand.
+
+texinfo.tex can be updated from ftp.gnu.org.  Check it still works
+with "make gmp.dvi", "make gmp.ps" and "make gmp.pdf".
+
+configfsf.guess and configfsf.sub can be updated from ftp.gnu.org (or
+from the "config" cvs module at subversions.gnu.org).  The gmp
+config.guess and config.sub wrappers are supposed to make such an
+update fairly painless.
+
+depcomp from automake is not needed because configure.in specifies
+automake with "no-dependencies".
+
+** How it works
+
+During development:
+
+    Input files                       Tool       Output files
+    ---------------------------------------------------------
+
+                                     aclocal
+    $prefix/share/aclocal*/*.m4 ----------------> aclocal.m4
+
+
+    configure.in \                   autoconf
+    aclocal.m4   / -----------------------------> configure
+
+
+    */Makefile.am \                  automake
+    configure.in  | ----------------------------> Makefile.in
+    aclocal.m4    /
+
+    configure.in \                  autoheader
+    aclocal.m4   / -----------------------------> config.in
+
+At build time:
+
+    Input files          Tool       Output files
+    --------------------------------------------
+
+    */Makefile.in  \   configure    / */Makefile
+    config.in      | -------------> | config.h
+    gmp-h.in       /                | config.m4
+                                    | gmp.h
+                                    \ fat.h  (fat binary build only)
+
+When configured with --enable-maintainer-mode the Makefiles include
+rules to re-run the necessary tools if the input files are changed.
+This can end up running a lot more things than are really necessary.
+
+If a build tree is in too much of a mess for those rules to work
+properly then a bootstrap can be done from the source directory with
+
+	aclocal
+	autoconf
+	automake
+	autoheader
+
+The autom4te.cache directory is created by autoconf to save some work
+in subsequent automake or autoheader runs.  It's recreated
+automatically if removed, it doesn't get distributed.
+
+** C++ configuration
+
+It's intended that the contents of libgmp.la won't vary according to
+whether --enable-cxx is selected.  This means that if C++ shared
+libraries don't work properly then a shared+static with --disable-cxx
+can be done for the C parts, then a static-only with --enable-cxx to
+get libgmpxx.
+
+libgmpxx.la uses some internals from libgmp.la, in order to share code
+between C and C++.  It's intended that libgmpxx can only be expected
+to work with libgmp from the same version of GMP.  If some of the
+shared internals change their interface, then it's proposed to rename
+them, for instance __gmp_doprint2 or the like, so as to provoke link
+errors rather than mysterious failures from a mismatch.
+
+* Development setups
+
+** General
+
+--disable-shared will make builds go much faster, though of course
+shared or shared+static should be tested too.
+
+--prefix to a dummy directory followed by "make install" will show
+what's installed.
+
+"make check" acts on the libgmp just built, and will ignore any other
+/usr/lib/libgmp, or at least it should do.  Libtool does various hairy
+things to ensure it hits the just-built library.
+
+** Long long limb testing
+
+On systems where gcc supports long long, but a limb is normally just a
+long, the following can be used to force long long for testing
+purposes.  It will probably run quite slowly.
+
+	./configure --host=none ABI=longlong
+
+** Function argument conversions
+
+When using gcc, configuring with something like
+
+	./configure CFLAGS="-g -Wall -Wconversion -Wno-sign-compare"
+
+can show where function parameters are being converted due to having
+function prototypes available, which won't happen in a K&R compiler.
+Doing this in combination with the long long limb setups above is
+good.
+
+Conversions between int and long aren't warned about by gcc when
+they're the same size, which is unfortunate because casts should be
+used in such cases, for the benefit of K&R compilers with int!=long
+and where the difference matters in function calls.
+
+* Other Notes
+
+** Compatibility
+
+compat.c is the home of functions retained for binary compatibility,
+    but now done by other means (like a macro).
+
+struct __mpz_struct etc - this must be retained for C++ compatibility.
+    C++ applications defining functions taking mpz_t etc parameters
+    will get this in the mangled name because C++ "sees though" the
+    typedef mpz_t to the underlying struct.
+
+__gmpn - note that glibc defines some __mpn symbols, old versions of
+    some mpn routines, which it uses for floating point printfs.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{https://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:
+
+@smallexample
+@group
+    with the Invariant Sections being @var{list their titles}, with
+    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+    being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1 Introduction to GNU MP
+************************
+
+GNU MP is a portable library written in C for arbitrary precision
+arithmetic on integers, rational numbers, and floating-point numbers.
+It aims to provide the fastest possible arithmetic for all applications
+that need higher precision than is directly supported by the basic C
+types.
+
+   Many applications use just a few hundred bits of precision; but some
+applications may need thousands or even millions of bits.  GMP is
+designed to give good performance for both, by choosing algorithms based
+on the sizes of the operands, and by carefully keeping the overhead at a
+minimum.
+
+   The speed of GMP is achieved by using fullwords as the basic
+arithmetic type, by using sophisticated algorithms, by including
+carefully optimized assembly code for the most common inner loops for
+many different CPUs, and by a general emphasis on speed (as opposed to
+simplicity or elegance).
+
+   There is assembly code for these CPUs: ARM Cortex-A9, Cortex-A15, and
+generic ARM, DEC Alpha 21064, 21164, and 21264, AMD K8 and K10 (sold
+under many brands, e.g.  Athlon64, Phenom, Opteron) Bulldozer, and
+Bobcat, Intel Pentium, Pentium Pro/II/III, Pentium 4, Core2, Nehalem,
+Sandy bridge, Haswell, generic x86, Intel IA-64, Motorola/IBM PowerPC 32
+and 64 such as POWER970, POWER5, POWER6, and POWER7, MIPS 32-bit and
+64-bit, SPARC 32-bit ad 64-bit with special support for all UltraSPARC
+models.  There is also assembly code for many obsolete CPUs.
+
+For up-to-date information on GMP, please see the GMP web pages at
+
+     <https://gmplib.org/>
+
+The latest version of the library is available at
+
+     <https://ftp.gnu.org/gnu/gmp/>
+
+   Many sites around the world mirror 'ftp.gnu.org', please use a mirror
+near you, see <https://www.gnu.org/order/ftp.html> for a full list.
+
+   There are three public mailing lists of interest.  One for release
+announcements, one for general questions and discussions about usage of
+the GMP library and one for bug reports.  For more information, see
+
+     <https://gmplib.org/mailman/listinfo/>.
+
+   The proper place for bug reports is <gmp-bugs@gmplib.org>.  See *note

+
+1.1 How to use this Manual
+==========================
+
+Everyone should read *note GMP Basics::.  If you need to install the
+library yourself, then read *note Installing GMP::.  If you have a
+system with multiple ABIs, then read *note ABI and ISA::, for the
+compiler options that must be used on applications.
+
+   The rest of the manual can be used for later reference, although it
+is probably a good idea to glance through it.

+
+2 Installing GMP
+****************
+
+GMP has an autoconf/automake/libtool based configuration system.  On a
+Unix-like system a basic build can be done with
+
+     ./configure
+     make
+
+Some self-tests can be run with
+
+     make check
+
+And you can install (under '/usr/local' by default) with
+
+     make install
+
+   If you experience problems, please report them to
+<gmp-bugs@gmplib.org>.  See *note Reporting Bugs::, for information on
+what to include in useful bug reports.

+
+
+File: gmp.info,  Node: Build Options,  Next: ABI and ISA,  Prev: Installing GMP,  Up: Installing GMP
+
+2.1 Build Options
+=================
+
+All the usual autoconf configure options are available, run './configure
+--help' for a summary.  The file 'INSTALL.autoconf' has some generic
+installation information too.
+
+Tools
+     'configure' requires various Unix-like tools.  See *note Notes for
+     Particular Systems::, for some options on non-Unix systems.
+
+     It might be possible to build without the help of 'configure',
+     certainly all the code is there, but unfortunately you'll be on
+     your own.
+
+Build Directory
+     To compile in a separate build directory, 'cd' to that directory,
+     and prefix the configure command with the path to the GMP source
+     directory.  For example
+
+          cd /my/build/dir
+          /my/sources/gmp-6.2.0/configure
+
+     Not all 'make' programs have the necessary features ('VPATH') to
+     support this.  In particular, SunOS and Slowaris 'make' have bugs
+     that make them unable to build in a separate directory.  Use GNU
+     'make' instead.
+
+'--prefix' and '--exec-prefix'
+     The '--prefix' option can be used in the normal way to direct GMP
+     to install under a particular tree.  The default is '/usr/local'.
+
+     '--exec-prefix' can be used to direct architecture-dependent files
+     like 'libgmp.a' to a different location.  This can be used to share
+     architecture-independent parts like the documentation, but separate
+     the dependent parts.  Note however that 'gmp.h' is
+     architecture-dependent since it encodes certain aspects of
+     'libgmp', so it will be necessary to ensure both '$prefix/include'
+     and '$exec_prefix/include' are available to the compiler.
+
+'--disable-shared', '--disable-static'
+     By default both shared and static libraries are built (where
+     possible), but one or other can be disabled.  Shared libraries
+     result in smaller executables and permit code sharing between
+     separate running processes, but on some CPUs are slightly slower,
+     having a small cost on each function call.
+
+Native Compilation, '--build=CPU-VENDOR-OS'
+     For normal native compilation, the system can be specified with
+     '--build'.  By default './configure' uses the output from running
+     './config.guess'.  On some systems './config.guess' can determine
+     the exact CPU type, on others it will be necessary to give it
+     explicitly.  For example,
+
+          ./configure --build=ultrasparc-sun-solaris2.7
+
+     In all cases the 'OS' part is important, since it controls how
+     libtool generates shared libraries.  Running './config.guess' is
+     the simplest way to see what it should be, if you don't know
+     already.
+
+Cross Compilation, '--host=CPU-VENDOR-OS'
+     When cross-compiling, the system used for compiling is given by
+     '--build' and the system where the library will run is given by
+     '--host'.  For example when using a FreeBSD Athlon system to build
+     GNU/Linux m68k binaries,
+
+          ./configure --build=athlon-pc-freebsd3.5 --host=m68k-mac-linux-gnu
+
+     Compiler tools are sought first with the host system type as a
+     prefix.  For example 'm68k-mac-linux-gnu-ranlib' is tried, then
+     plain 'ranlib'.  This makes it possible for a set of
+     cross-compiling tools to co-exist with native tools.  The prefix is
+     the argument to '--host', and this can be an alias, such as
+     'm68k-linux'.  But note that tools don't have to be setup this way,
+     it's enough to just have a 'PATH' with a suitable cross-compiling
+     'cc' etc.
+
+     Compiling for a different CPU in the same family as the build
+     system is a form of cross-compilation, though very possibly this
+     would merely be special options on a native compiler.  In any case
+     './configure' avoids depending on being able to run code on the
+     build system, which is important when creating binaries for a newer
+     CPU since they very possibly won't run on the build system.
+
+     In all cases the compiler must be able to produce an executable (of
+     whatever format) from a standard C 'main'.  Although only object
+     files will go to make up 'libgmp', './configure' uses linking tests
+     for various purposes, such as determining what functions are
+     available on the host system.
+
+     Currently a warning is given unless an explicit '--build' is used
+     when cross-compiling, because it may not be possible to correctly
+     guess the build system type if the 'PATH' has only a
+     cross-compiling 'cc'.
+
+     Note that the '--target' option is not appropriate for GMP.  It's
+     for use when building compiler tools, with '--host' being where
+     they will run, and '--target' what they'll produce code for.
+     Ordinary programs or libraries like GMP are only interested in the
+     '--host' part, being where they'll run.  (Some past versions of GMP
+     used '--target' incorrectly.)
+
+CPU types
+     In general, if you want a library that runs as fast as possible,
+     you should configure GMP for the exact CPU type your system uses.
+     However, this may mean the binaries won't run on older members of
+     the family, and might run slower on other members, older or newer.
+     The best idea is always to build GMP for the exact machine type you
+     intend to run it on.
+
+     The following CPUs have specific support.  See 'configure.ac' for
+     details of what code and compiler options they select.
+
+        * Alpha: alpha, alphaev5, alphaev56, alphapca56, alphapca57,
+          alphaev6, alphaev67, alphaev68 alphaev7
+
+        * Cray: c90, j90, t90, sv1
+
+        * HPPA: hppa1.0, hppa1.1, hppa2.0, hppa2.0n, hppa2.0w, hppa64
+
+        * IA-64: ia64, itanium, itanium2
+
+        * MIPS: mips, mips3, mips64
+
+        * Motorola: m68k, m68000, m68010, m68020, m68030, m68040,
+          m68060, m68302, m68360, m88k, m88110
+
+        * POWER: power, power1, power2, power2sc

+        * PowerPC: powerpc, powerpc64, powerpc401, powerpc403,
+          powerpc405, powerpc505, powerpc601, powerpc602, powerpc603,
+          powerpc603e, powerpc604, powerpc604e, powerpc620, powerpc630,
+          powerpc740, powerpc7400, powerpc7450, powerpc750, powerpc801,
+          powerpc821, powerpc823, powerpc860, powerpc970
+
+        * SPARC: sparc, sparcv8, microsparc, supersparc, sparcv9,
+          ultrasparc, ultrasparc2, ultrasparc2i, ultrasparc3, sparc64
+
+        * x86 family: i386, i486, i586, pentium, pentiummmx, pentiumpro,
+          pentium2, pentium3, pentium4, k6, k62, k63, athlon, amd64,
+          viac3, viac32
+
+        * Other: arm, sh, sh2, vax,
+
+     CPUs not listed will use generic C code.
+
+Generic C Build
+     If some of the assembly code causes problems, or if otherwise
+     desired, the generic C code can be selected with the configure
+     '--disable-assembly'.
+
+     Note that this will run quite slowly, but it should be portable and
+     should at least make it possible to get something running if all
+     else fails.
+
+Fat binary, '--enable-fat'
+     Using '--enable-fat' selects a "fat binary" build on x86, where
+     optimized low level subroutines are chosen at runtime according to
+     the CPU detected.  This means more code, but gives good performance
+     on all x86 chips.  (This option might become available for more
+     architectures in the future.)
+
+'ABI'
+     On some systems GMP supports multiple ABIs (application binary
+     interfaces), meaning data type sizes and calling conventions.  By
+     default GMP chooses the best ABI available, but a particular ABI
+     can be selected.  For example
+
+          ./configure --host=mips64-sgi-irix6 ABI=n32
+
+     See *note ABI and ISA::, for the available choices on relevant
+     CPUs, and what applications need to do.
+
+'CC', 'CFLAGS'
+     By default the C compiler used is chosen from among some likely
+     candidates, with 'gcc' normally preferred if it's present.  The
+     usual 'CC=whatever' can be passed to './configure' to choose
+     something different.
+
+     For various systems, default compiler flags are set based on the
+     CPU and compiler.  The usual 'CFLAGS="-whatever"' can be passed to
+     './configure' to use something different or to set good flags for
+     systems GMP doesn't otherwise know.
+
+     The 'CC' and 'CFLAGS' used are printed during './configure', and
+     can be found in each generated 'Makefile'.  This is the easiest way
+     to check the defaults when considering changing or adding
+     something.
+
+     Note that when 'CC' and 'CFLAGS' are specified on a system
+     supporting multiple ABIs it's important to give an explicit
+     'ABI=whatever', since GMP can't determine the ABI just from the
+     flags and won't be able to select the correct assembly code.
+
+     If just 'CC' is selected then normal default 'CFLAGS' for that
+     compiler will be used (if GMP recognises it).  For example 'CC=gcc'
+     can be used to force the use of GCC, with default flags (and
+     default ABI).
+
+'CPPFLAGS'
+     Any flags like '-D' defines or '-I' includes required by the
+     preprocessor should be set in 'CPPFLAGS' rather than 'CFLAGS'.
+     Compiling is done with both 'CPPFLAGS' and 'CFLAGS', but
+     preprocessing uses just 'CPPFLAGS'.  This distinction is because
+     most preprocessors won't accept all the flags the compiler does.
+     Preprocessing is done separately in some configure tests.
+
+'CC_FOR_BUILD'
+     Some build-time programs are compiled and run to generate
+     host-specific data tables.  'CC_FOR_BUILD' is the compiler used for
+     this.  It doesn't need to be in any particular ABI or mode, it
+     merely needs to generate executables that can run.  The default is
+     to try the selected 'CC' and some likely candidates such as 'cc'
+     and 'gcc', looking for something that works.
+
+     No flags are used with 'CC_FOR_BUILD' because a simple invocation
+     like 'cc foo.c' should be enough.  If some particular options are
+     required they can be included as for instance 'CC_FOR_BUILD="cc
+     -whatever"'.
+
+C++ Support, '--enable-cxx'
+     C++ support in GMP can be enabled with '--enable-cxx', in which
+     case a C++ compiler will be required.  As a convenience
+     '--enable-cxx=detect' can be used to enable C++ support only if a
+     compiler can be found.  The C++ support consists of a library
+     'libgmpxx.la' and header file 'gmpxx.h' (*note Headers and
+     Libraries::).
+
+     A separate 'libgmpxx.la' has been adopted rather than having C++
+     objects within 'libgmp.la' in order to ensure dynamic linked C
+     programs aren't bloated by a dependency on the C++ standard
+     library, and to avoid any chance that the C++ compiler could be
+     required when linking plain C programs.
+
+     'libgmpxx.la' will use certain internals from 'libgmp.la' and can
+     only be expected to work with 'libgmp.la' from the same GMP
+     version.  Future changes to the relevant internals will be
+     accompanied by renaming, so a mismatch will cause unresolved
+     symbols rather than perhaps mysterious misbehaviour.
+
+     In general 'libgmpxx.la' will be usable only with the C++ compiler
+     that built it, since name mangling and runtime support are usually
+     incompatible between different compilers.
+
+'CXX', 'CXXFLAGS'
+     When C++ support is enabled, the C++ compiler and its flags can be
+     set with variables 'CXX' and 'CXXFLAGS' in the usual way.  The
+     default for 'CXX' is the first compiler that works from a list of
+     likely candidates, with 'g++' normally preferred when available.
+     The default for 'CXXFLAGS' is to try 'CFLAGS', 'CFLAGS' without
+     '-g', then for 'g++' either '-g -O2' or '-O2', or for other
+     compilers '-g' or nothing.  Trying 'CFLAGS' this way is convenient
+     when using 'gcc' and 'g++' together, since the flags for 'gcc' will
+     usually suit 'g++'.
+
+     It's important that the C and C++ compilers match, meaning their
+     startup and runtime support routines are compatible and that they
+     generate code in the same ABI (if there's a choice of ABIs on the
+     system).  './configure' isn't currently able to check these things
+     very well itself, so for that reason '--disable-cxx' is the
+     default, to avoid a build failure due to a compiler mismatch.
+     Perhaps this will change in the future.
+
+     Incidentally, it's normally not good enough to set 'CXX' to the
+     same as 'CC'.  Although 'gcc' for instance recognises 'foo.cc' as
+     C++ code, only 'g++' will invoke the linker the right way when
+     building an executable or shared library from C++ object files.
+
+Temporary Memory, '--enable-alloca=<choice>'
+     GMP allocates temporary workspace using one of the following three
+     methods, which can be selected with for instance
+     '--enable-alloca=malloc-reentrant'.
+
+        * 'alloca' - C library or compiler builtin.
+        * 'malloc-reentrant' - the heap, in a re-entrant fashion.
+        * 'malloc-notreentrant' - the heap, with global variables.
+
+     For convenience, the following choices are also available.
+     '--disable-alloca' is the same as 'no'.
+
+        * 'yes' - a synonym for 'alloca'.
+        * 'no' - a synonym for 'malloc-reentrant'.
+        * 'reentrant' - 'alloca' if available, otherwise
+          'malloc-reentrant'.  This is the default.
+        * 'notreentrant' - 'alloca' if available, otherwise
+          'malloc-notreentrant'.
+
+     'alloca' is reentrant and fast, and is recommended.  It actually
+     allocates just small blocks on the stack; larger ones use
+     malloc-reentrant.
+
+     'malloc-reentrant' is, as the name suggests, reentrant and thread
+     safe, but 'malloc-notreentrant' is faster and should be used if
+     reentrancy is not required.
+
+     The two malloc methods in fact use the memory allocation functions
+     selected by 'mp_set_memory_functions', these being 'malloc' and
+     friends by default.  *Note Custom Allocation::.
+
+     An additional choice '--enable-alloca=debug' is available, to help
+     when debugging memory related problems (*note Debugging::).
+
+FFT Multiplication, '--disable-fft'
+     By default multiplications are done using Karatsuba, 3-way Toom,
+     higher degree Toom, and Fermat FFT.  The FFT is only used on large
+     to very large operands and can be disabled to save code size if
+     desired.
+
+Assertion Checking, '--enable-assert'
+     This option enables some consistency checking within the library.
+     This can be of use while debugging, *note Debugging::.
+
+Execution Profiling, '--enable-profiling=prof/gprof/instrument'
+     Enable profiling support, in one of various styles, *note
+     Profiling::.
+
+'MPN_PATH'
+     Various assembly versions of each mpn subroutines are provided.
+     For a given CPU, a search is made though a path to choose a version
+     of each.  For example 'sparcv8' has
+
+          MPN_PATH="sparc32/v8 sparc32 generic"
+
+     which means look first for v8 code, then plain sparc32 (which is
+     v7), and finally fall back on generic C.  Knowledgeable users with
+     special requirements can specify a different path.  Normally this
+     is completely unnecessary.

+
+2.2 ABI and ISA
+===============
+
+ABI (Application Binary Interface) refers to the calling conventions
+between functions, meaning what registers are used and what sizes the
+various C data types are.  ISA (Instruction Set Architecture) refers to
+the instructions and registers a CPU has available.
+
+   Some 64-bit ISA CPUs have both a 64-bit ABI and a 32-bit ABI defined,
+the latter for compatibility with older CPUs in the family.  GMP
+supports some CPUs like this in both ABIs.  In fact within GMP 'ABI'
+means a combination of chip ABI, plus how GMP chooses to use it.  For
+example in some 32-bit ABIs, GMP may support a limb as either a 32-bit
+'long' or a 64-bit 'long long'.
+
+   By default GMP chooses the best ABI available for a given system, and
+this generally gives significantly greater speed.  But an ABI can be
+chosen explicitly to make GMP compatible with other libraries, or
+particular application requirements.  For example,
+
+     ./configure ABI=32
+
+   In all cases it's vital that all object code used in a given program
+is compiled for the same ABI.
+
+   Usually a limb is implemented as a 'long'.  When a 'long long' limb
+is used this is encoded in the generated 'gmp.h'.  This is convenient
+for applications, but it does mean that 'gmp.h' will vary, and can't be
+just copied around.  'gmp.h' remains compiler independent though, since
+all compilers for a particular ABI will be expected to use the same limb
+type.
+
+   Currently no attempt is made to follow whatever conventions a system
+has for installing library or header files built for a particular ABI.
+This will probably only matter when installing multiple builds of GMP,
+and it might be as simple as configuring with a special 'libdir', or it
+might require more than that.  Note that builds for different ABIs need
+to done separately, with a fresh './configure' and 'make' each.
+
+
+AMD64 ('x86_64')
+     On AMD64 systems supporting both 32-bit and 64-bit modes for
+     applications, the following ABI choices are available.
+
+     'ABI=64'
+          The 64-bit ABI uses 64-bit limbs and pointers and makes full
+          use of the chip architecture.  This is the default.
+          Applications will usually not need special compiler flags, but
+          for reference the option is
+
+               gcc  -m64
+
+     'ABI=32'
+          The 32-bit ABI is the usual i386 conventions.  This will be
+          slower, and is not recommended except for inter-operating with
+          other code not yet 64-bit capable.  Applications must be
+          compiled with
+
+               gcc  -m32
+
+          (In GCC 2.95 and earlier there's no '-m32' option, it's the
+          only mode.)
+
+     'ABI=x32'
+          The x32 ABI uses 64-bit limbs but 32-bit pointers.  Like the
+          64-bit ABI, it makes full use of the chip's arithmetic
+          capabilities.  This ABI is not supported by all operating
+          systems.
+
+               gcc  -mx32
+
+
+HPPA 2.0 ('hppa2.0*', 'hppa64')
+     'ABI=2.0w'
+          The 2.0w ABI uses 64-bit limbs and pointers and is available
+          on HP-UX 11 or up.  Applications must be compiled with
+
+               gcc [built for 2.0w]
+               cc  +DD64
+
+     'ABI=2.0n'
+          The 2.0n ABI means the 32-bit HPPA 1.0 ABI and all its normal
+          calling conventions, but with 64-bit instructions permitted
+          within functions.  GMP uses a 64-bit 'long long' for a limb.
+          This ABI is available on hppa64 GNU/Linux and on HP-UX 10 or
+          higher.  Applications must be compiled with
+
+               gcc [built for 2.0n]
+               cc  +DA2.0 +e
+
+          Note that current versions of GCC (eg. 3.2) don't generate
+          64-bit instructions for 'long long' operations and so may be
+          slower than for 2.0w.  (The GMP assembly code is the same
+          though.)
+
+     'ABI=1.0'
+          HPPA 2.0 CPUs can run all HPPA 1.0 and 1.1 code in the 32-bit
+          HPPA 1.0 ABI.  No special compiler options are needed for
+          applications.
+
+     All three ABIs are available for CPU types 'hppa2.0w', 'hppa2.0'
+     and 'hppa64', but for CPU type 'hppa2.0n' only 2.0n or 1.0 are
+     considered.
+
+     Note that GCC on HP-UX has no options to choose between 2.0n and
+     2.0w modes, unlike HP 'cc'.  Instead it must be built for one or
+     the other ABI.  GMP will detect how it was built, and skip to the
+     corresponding 'ABI'.
+
+
+IA-64 under HP-UX ('ia64*-*-hpux*', 'itanium*-*-hpux*')
+     HP-UX supports two ABIs for IA-64.  GMP performance is the same in
+     both.
+
+     'ABI=32'
+          In the 32-bit ABI, pointers, 'int's and 'long's are 32 bits
+          and GMP uses a 64 bit 'long long' for a limb.  Applications
+          can be compiled without any special flags since this ABI is
+          the default in both HP C and GCC, but for reference the flags
+          are
+
+               gcc  -milp32
+               cc   +DD32
+
+     'ABI=64'
+          In the 64-bit ABI, 'long's and pointers are 64 bits and GMP
+          uses a 'long' for a limb.  Applications must be compiled with
+
+               gcc  -mlp64
+               cc   +DD64
+
+     On other IA-64 systems, GNU/Linux for instance, 'ABI=64' is the
+     only choice.
+
+
+MIPS under IRIX 6 ('mips*-*-irix[6789]')
+     IRIX 6 always has a 64-bit MIPS 3 or better CPU, and supports ABIs
+     o32, n32, and 64.  n32 or 64 are recommended, and GMP performance
+     will be the same in each.  The default is n32.
+
+     'ABI=o32'
+          The o32 ABI is 32-bit pointers and integers, and no 64-bit
+          operations.  GMP will be slower than in n32 or 64, this option
+          only exists to support old compilers, eg. GCC 2.7.2.
+          Applications can be compiled with no special flags on an old
+          compiler, or on a newer compiler with
+
+               gcc  -mabi=32
+               cc   -32
+
+     'ABI=n32'
+          The n32 ABI is 32-bit pointers and integers, but with a 64-bit
+          limb using a 'long long'.  Applications must be compiled with
+
+               gcc  -mabi=n32
+               cc   -n32
+
+     'ABI=64'
+          The 64-bit ABI is 64-bit pointers and integers.  Applications
+          must be compiled with
+
+               gcc  -mabi=64
+               cc   -64
+
+     Note that MIPS GNU/Linux, as of kernel version 2.2, doesn't have
+     the necessary support for n32 or 64 and so only gets a 32-bit limb
+     and the MIPS 2 code.
+
+
+PowerPC 64 ('powerpc64', 'powerpc620', 'powerpc630', 'powerpc970', 'power4', 'power5')
+     'ABI=mode64'
+          The AIX 64 ABI uses 64-bit limbs and pointers and is the
+          default on PowerPC 64 '*-*-aix*' systems.  Applications must
+          be compiled with
+
+               gcc  -maix64
+               xlc  -q64
+
+          On 64-bit GNU/Linux, BSD, and Mac OS X/Darwin systems, the
+          applications must be compiled with
+
+               gcc  -m64
+
+     'ABI=mode32'
+          The 'mode32' ABI uses a 64-bit 'long long' limb but with the
+          chip still in 32-bit mode and using 32-bit calling
+          conventions.  This is the default for systems where the true
+          64-bit ABI is unavailable.  No special compiler options are
+          typically needed for applications.  This ABI is not available
+          under AIX.
+
+     'ABI=32'
+          This is the basic 32-bit PowerPC ABI, with a 32-bit limb.  No
+          special compiler options are needed for applications.
+
+     GMP's speed is greatest for the 'mode64' ABI, the 'mode32' ABI is
+     2nd best.  In 'ABI=32' only the 32-bit ISA is used and this doesn't
+     make full use of a 64-bit chip.
+
+
+Sparc V9 ('sparc64', 'sparcv9', 'ultrasparc*')
+     'ABI=64'
+          The 64-bit V9 ABI is available on the various BSD sparc64
+          ports, recent versions of Sparc64 GNU/Linux, and Solaris 2.7
+          and up (when the kernel is in 64-bit mode).  GCC 3.2 or
+          higher, or Sun 'cc' is required.  On GNU/Linux, depending on
+          the default 'gcc' mode, applications must be compiled with
+
+               gcc  -m64
+
+          On Solaris applications must be compiled with
+
+               gcc  -m64 -mptr64 -Wa,-xarch=v9 -mcpu=v9
+               cc   -xarch=v9
+
+          On the BSD sparc64 systems no special options are required,
+          since 64-bits is the only ABI available.
+
+     'ABI=32'
+          For the basic 32-bit ABI, GMP still uses as much of the V9 ISA
+          as it can.  In the Sun documentation this combination is known
+          as "v8plus".  On GNU/Linux, depending on the default 'gcc'
+          mode, applications may need to be compiled with
+
+               gcc  -m32
+
+          On Solaris, no special compiler options are required for
+          applications, though using something like the following is
+          recommended.  ('gcc' 2.8 and earlier only support '-mv8'
+          though.)
+
+               gcc  -mv8plus
+               cc   -xarch=v8plus
+
+     GMP speed is greatest in 'ABI=64', so it's the default where
+     available.  The speed is partly because there are extra registers
+     available and partly because 64-bits is considered the more
+     important case and has therefore had better code written for it.
+
+     Don't be confused by the names of the '-m' and '-x' compiler
+     options, they're called 'arch' but effectively control both ABI and
+     ISA.
+
+     On Solaris 2.6 and earlier, only 'ABI=32' is available since the
+     kernel doesn't save all registers.
+
+     On Solaris 2.7 with the kernel in 32-bit mode, a normal native
+     build will reject 'ABI=64' because the resulting executables won't
+     run.  'ABI=64' can still be built if desired by making it look like
+     a cross-compile, for example
+
+          ./configure --build=none --host=sparcv9-sun-solaris2.7 ABI=64

+
+2.3 Notes for Package Builds
+============================
+
+GMP should present no great difficulties for packaging in a binary
+distribution.
+
+   Libtool is used to build the library and '-version-info' is set
+appropriately, having started from '3:0:0' in GMP 3.0 (*note Library
+interface versions: (libtool)Versioning.).
+
+   The GMP 4 series will be upwardly binary compatible in each release
+and will be upwardly binary compatible with all of the GMP 3 series.
+Additional function interfaces may be added in each release, so on
+systems where libtool versioning is not fully checked by the loader an
+auxiliary mechanism may be needed to express that a dynamic linked
+application depends on a new enough GMP.
+
+   An auxiliary mechanism may also be needed to express that
+'libgmpxx.la' (from '--enable-cxx', *note Build Options::) requires
+'libgmp.la' from the same GMP version, since this is not done by the
+libtool versioning, nor otherwise.  A mismatch will result in unresolved
+symbols from the linker, or perhaps the loader.
+
+   When building a package for a CPU family, care should be taken to use
+'--host' (or '--build') to choose the least common denominator among the
+CPUs which might use the package.  For example this might mean plain
+'sparc' (meaning V7) for SPARCs.
+
+   For x86s, '--enable-fat' sets things up for a fat binary build,
+making a runtime selection of optimized low level routines.  This is a
+good choice for packaging to run on a range of x86 chips.
+
+   Users who care about speed will want GMP built for their exact CPU
+type, to make best use of the available optimizations.  Providing a way
+to suitably rebuild a package may be useful.  This could be as simple as
+making it possible for a user to omit '--build' (and '--host') so
+'./config.guess' will detect the CPU.  But a way to manually specify a
+'--build' will be wanted for systems where './config.guess' is inexact.
+
+   On systems with multiple ABIs, a packaged build will need to decide
+which among the choices is to be provided, see *note ABI and ISA::.  A
+given run of './configure' etc will only build one ABI.  If a second ABI
+is also required then a second run of './configure' etc must be made,
+starting from a clean directory tree ('make distclean').
+
+   As noted under "ABI and ISA", currently no attempt is made to follow
+system conventions for install locations that vary with ABI, such as
+'/usr/lib/sparcv9' for 'ABI=64' as opposed to '/usr/lib' for 'ABI=32'.
+A package build can override 'libdir' and other standard variables as
+necessary.
+
+   Note that 'gmp.h' is a generated file, and will be architecture and
+ABI dependent.  When attempting to install two ABIs simultaneously it
+will be important that an application compile gets the correct 'gmp.h'
+for its desired ABI.  If compiler include paths don't vary with ABI
+options then it might be necessary to create a '/usr/include/gmp.h'
+which tests preprocessor symbols and chooses the correct actual 'gmp.h'.
+

+
+2.4 Notes for Particular Systems
+================================
+
+AIX 3 and 4
+     On systems '*-*-aix[34]*' shared libraries are disabled by default,
+     since some versions of the native 'ar' fail on the convenience
+     libraries used.  A shared build can be attempted with
+
+          ./configure --enable-shared --disable-static
+
+     Note that the '--disable-static' is necessary because in a shared
+     build libtool makes 'libgmp.a' a symlink to 'libgmp.so', apparently
+     for the benefit of old versions of 'ld' which only recognise '.a',
+     but unfortunately this is done even if a fully functional 'ld' is
+     available.
+
+ARM
+     On systems 'arm*-*-*', versions of GCC up to and including 2.95.3
+     have a bug in unsigned division, giving wrong results for some
+     operands.  GMP './configure' will demand GCC 2.95.4 or later.
+
+Compaq C++
+     Compaq C++ on OSF 5.1 has two flavours of 'iostream', a standard
+     one and an old pre-standard one (see 'man iostream_intro').  GMP
+     can only use the standard one, which unfortunately is not the
+     default but must be selected by defining '__USE_STD_IOSTREAM'.
+     Configure with for instance
+
+          ./configure --enable-cxx CPPFLAGS=-D__USE_STD_IOSTREAM
+
+Floating Point Mode
+     On some systems, the hardware floating point has a control mode
+     which can set all operations to be done in a particular precision,
+     for instance single, double or extended on x86 systems (x87
+     floating point).  The GMP functions involving a 'double' cannot be
+     expected to operate to their full precision when the hardware is in
+     single precision mode.  Of course this affects all code, including
+     application code, not just GMP.
+
+FreeBSD 7.x, 8.x, 9.0, 9.1, 9.2
+     'm4' in these releases of FreeBSD has an eval function which
+     ignores its 2nd and 3rd arguments, which makes it unsuitable for
+     '.asm' file processing.  './configure' will detect the problem and
+     either abort or choose another m4 in the 'PATH'.  The bug is fixed
+     in FreeBSD 9.3 and 10.0, so either upgrade or use GNU m4.  Note
+     that the FreeBSD package system installs GNU m4 under the name
+     'gm4', which GMP cannot guess.
+
+FreeBSD 7.x, 8.x, 9.x
+     GMP releases starting with 6.0 do not support 'ABI=32' on
+     FreeBSD/amd64 prior to release 10.0 of the system.  The cause is a
+     broken 'limits.h', which GMP no longer works around.
+
+MS-DOS and MS Windows
+     On an MS-DOS system DJGPP can be used to build GMP, and on an MS
+     Windows system Cygwin, DJGPP and MINGW can be used.  All three are
+     excellent ports of GCC and the various GNU tools.
+
+          <https://www.cygwin.com/>
+          <http://www.delorie.com/djgpp/>
+          <http://www.mingw.org/>
+
+     Microsoft also publishes an Interix "Services for Unix" which can
+     be used to build GMP on Windows (with a normal './configure'), but
+     it's not free software.
+
+MS Windows DLLs
+     On systems '*-*-cygwin*', '*-*-mingw*' and '*-*-pw32*' by default
+     GMP builds only a static library, but a DLL can be built instead
+     using
+
+          ./configure --disable-static --enable-shared
+
+     Static and DLL libraries can't both be built, since certain export
+     directives in 'gmp.h' must be different.
+
+     A MINGW DLL build of GMP can be used with Microsoft C.  Libtool
+     doesn't install a '.lib' format import library, but it can be
+     created with MS 'lib' as follows, and copied to the install
+     directory.  Similarly for 'libmp' and 'libgmpxx'.
+
+          cd .libs
+          lib /def:libgmp-3.dll.def /out:libgmp-3.lib
+
+     MINGW uses the C runtime library 'msvcrt.dll' for I/O, so
+     applications wanting to use the GMP I/O routines must be compiled
+     with 'cl /MD' to do the same.  If one of the other C runtime
+     library choices provided by MS C is desired then the suggestion is
+     to use the GMP string functions and confine I/O to the application.
+
+Motorola 68k CPU Types
+     'm68k' is taken to mean 68000.  'm68020' or higher will give a
+     performance boost on applicable CPUs.  'm68360' can be used for
+     CPU32 series chips.  'm68302' can be used for "Dragonball" series
+     chips, though this is merely a synonym for 'm68000'.
+
+NetBSD 5.x
+     'm4' in these releases of NetBSD has an eval function which ignores
+     its 2nd and 3rd arguments, which makes it unsuitable for '.asm'
+     file processing.  './configure' will detect the problem and either
+     abort or choose another m4 in the 'PATH'.  The bug is fixed in
+     NetBSD 6, so either upgrade or use GNU m4.  Note that the NetBSD
+     package system installs GNU m4 under the name 'gm4', which GMP
+     cannot guess.
+
+OpenBSD 2.6
+     'm4' in this release of OpenBSD has a bug in 'eval' that makes it
+     unsuitable for '.asm' file processing.  './configure' will detect
+     the problem and either abort or choose another m4 in the 'PATH'.
+     The bug is fixed in OpenBSD 2.7, so either upgrade or use GNU m4.
+
+Power CPU Types
+     In GMP, CPU types 'power*' and 'powerpc*' will each use
+     instructions not available on the other, so it's important to
+     choose the right one for the CPU that will be used.  Currently GMP
+     has no assembly code support for using just the common instruction
+     subset.  To get executables that run on both, the current
+     suggestion is to use the generic C code ('--disable-assembly'),
+     possibly with appropriate compiler options (like '-mcpu=common' for
+     'gcc').  CPU 'rs6000' (which is not a CPU but a family of
+     workstations) is accepted by 'config.sub', but is currently
+     equivalent to '--disable-assembly'.
+
+Sparc CPU Types
+     'sparcv8' or 'supersparc' on relevant systems will give a
+     significant performance increase over the V7 code selected by plain
+     'sparc'.
+
+Sparc App Regs
+     The GMP assembly code for both 32-bit and 64-bit Sparc clobbers the
+     "application registers" 'g2', 'g3' and 'g4', the same way that the
+     GCC default '-mapp-regs' does (*note SPARC Options: (gcc)SPARC
+     Options.).
+
+     This makes that code unsuitable for use with the special V9
+     '-mcmodel=embmedany' (which uses 'g4' as a data segment pointer),
+     and for applications wanting to use those registers for special
+     purposes.  In these cases the only suggestion currently is to build
+     GMP with '--disable-assembly' to avoid the assembly code.
+
+SunOS 4
+     '/usr/bin/m4' lacks various features needed to process '.asm'
+     files, and instead './configure' will automatically use
+     '/usr/5bin/m4', which we believe is always available (if not then
+     use GNU m4).
+
+x86 CPU Types
+     'i586', 'pentium' or 'pentiummmx' code is good for its intended P5
+     Pentium chips, but quite slow when run on Intel P6 class chips
+     (PPro, P-II, P-III).  'i386' is a better choice when making
+     binaries that must run on both.
+
+x86 MMX and SSE2 Code
+     If the CPU selected has MMX code but the assembler doesn't support
+     it, a warning is given and non-MMX code is used instead.  This will
+     be an inferior build, since the MMX code that's present is there
+     because it's faster than the corresponding plain integer code.  The
+     same applies to SSE2.
+
+     Old versions of 'gas' don't support MMX instructions, in particular
+     version 1.92.3 that comes with FreeBSD 2.2.8 or the more recent
+     OpenBSD 3.1 doesn't.
+
+     Solaris 2.6 and 2.7 'as' generate incorrect object code for
+     register to register 'movq' instructions, and so can't be used for
+     MMX code.  Install a recent 'gas' if MMX code is wanted on these
+     systems.

+2.5 Known Build Problems
+========================
+
+You might find more up-to-date information at <https://gmplib.org/>.
+
+Compiler link options
+     The version of libtool currently in use rather aggressively strips
+     compiler options when linking a shared library.  This will
+     hopefully be relaxed in the future, but for now if this is a
+     problem the suggestion is to create a little script to hide them,
+     and for instance configure with
+
+          ./configure CC=gcc-with-my-options
+
+DJGPP ('*-*-msdosdjgpp*')
+     The DJGPP port of 'bash' 2.03 is unable to run the 'configure'
+     script, it exits silently, having died writing a preamble to
+     'config.log'.  Use 'bash' 2.04 or higher.
+
+     'make all' was found to run out of memory during the final
+     'libgmp.la' link on one system tested, despite having 64Mb
+     available.  Running 'make libgmp.la' directly helped, perhaps
+     recursing into the various subdirectories uses up memory.
+
+GNU binutils 'strip' prior to 2.12
+     'strip' from GNU binutils 2.11 and earlier should not be used on
+     the static libraries 'libgmp.a' and 'libmp.a' since it will discard
+     all but the last of multiple archive members with the same name,
+     like the three versions of 'init.o' in 'libgmp.a'.  Binutils 2.12
+     or higher can be used successfully.
+
+     The shared libraries 'libgmp.so' and 'libmp.so' are not affected by
+     this and any version of 'strip' can be used on them.
+
+'make' syntax error
+     On certain versions of SCO OpenServer 5 and IRIX 6.5 the native
+     'make' is unable to handle the long dependencies list for
+     'libgmp.la'.  The symptom is a "syntax error" on the following line
+     of the top-level 'Makefile'.
+
+          libgmp.la: $(libgmp_la_OBJECTS) $(libgmp_la_DEPENDENCIES)
+
+     Either use GNU Make, or as a workaround remove
+     '$(libgmp_la_DEPENDENCIES)' from that line (which will make the
+     initial build work, but if any recompiling is done 'libgmp.la'
+     might not be rebuilt).
+
+MacOS X ('*-*-darwin*')
+     Libtool currently only knows how to create shared libraries on
+     MacOS X using the native 'cc' (which is a modified GCC), not a
+     plain GCC.  A static-only build should work though
+     ('--disable-shared').
+
+NeXT prior to 3.3
+     The system compiler on old versions of NeXT was a massacred and old
+     GCC, even if it called itself 'cc'.  This compiler cannot be used
+     to build GMP, you need to get a real GCC, and install that.  (NeXT
+     may have fixed this in release 3.3 of their system.)
+
+POWER and PowerPC
+     Bugs in GCC 2.7.2 (and 2.6.3) mean it can't be used to compile GMP
+     on POWER or PowerPC.  If you want to use GCC for these machines,
+     get GCC 2.7.2.1 (or later).
+
+Sequent Symmetry
+     Use the GNU assembler instead of the system assembler, since the
+     latter has serious bugs.
+
+Solaris 2.6
+     The system 'sed' prints an error "Output line too long" when
+     libtool builds 'libgmp.la'.  This doesn't seem to cause any obvious
+     ill effects, but GNU 'sed' is recommended, to avoid any doubt.
+
+Sparc Solaris 2.7 with gcc 2.95.2 in 'ABI=32'
+     A shared library build of GMP seems to fail in this combination, it
+     builds but then fails the tests, apparently due to some incorrect
+     data relocations within 'gmp_randinit_lc_2exp_size'.  The exact
+     cause is unknown, '--disable-shared' is recommended.

+
+2.6 Performance optimization
+============================
+
+For optimal performance, build GMP for the exact CPU type of the target
+computer, see *note Build Options::.
+
+   Unlike what is the case for most other programs, the compiler
+typically doesn't matter much, since GMP uses assembly language for the
+most critical operation.
+
+   In particular for long-running GMP applications, and applications
+demanding extremely large numbers, building and running the 'tuneup'
+program in the 'tune' subdirectory, can be important.  For example,
+
+     cd tune
+     make tuneup
+     ./tuneup
+
+   will generate better contents for the 'gmp-mparam.h' parameter file.
+
+   To use the results, put the output in the file indicated in the
+'Parameters for ...' header.  Then recompile from scratch.
+
+   The 'tuneup' program takes one useful parameter, '-f NNN', which
+instructs the program how long to check FFT multiply parameters.  If
+you're going to use GMP for extremely large numbers, you may want to run
+'tuneup' with a large NNN value.

+
+3.1 Headers and Libraries
+=========================
+
+All declarations needed to use GMP are collected in the include file
+'gmp.h'.  It is designed to work with both C and C++ compilers.
+
+     #include <gmp.h>
+
+   Note however that prototypes for GMP functions with 'FILE *'
+parameters are only provided if '<stdio.h>' is included too.
+
+     #include <stdio.h>
+     #include <gmp.h>
+
+   Likewise '<stdarg.h>' is required for prototypes with 'va_list'
+parameters, such as 'gmp_vprintf'.  And '<obstack.h>' for prototypes
+with 'struct obstack' parameters, such as 'gmp_obstack_printf', when
+available.
+
+   All programs using GMP must link against the 'libgmp' library.  On a
+typical Unix-like system this can be done with '-lgmp', for example
+
+     gcc myprogram.c -lgmp
+
+   GMP C++ functions are in a separate 'libgmpxx' library.  This is
+built and installed if C++ support has been enabled (*note Build
+Options::).  For example,
+
+     g++ mycxxprog.cc -lgmpxx -lgmp
+
+   GMP is built using Libtool and an application can use that to link if
+desired, *note GNU Libtool: (libtool)Top.
+
+   If GMP has been installed to a non-standard location then it may be
+necessary to use '-I' and '-L' compiler options to point to the right
+directories, and some sort of run-time path for a shared library.

+
+3.2 Nomenclature and Types
+==========================
+
+In this manual, "integer" usually means a multiple precision integer, as
+defined by the GMP library.  The C data type for such integers is
+'mpz_t'.  Here are some examples of how to declare such integers:
+
+     mpz_t sum;
+
+     struct foo { mpz_t x, y; };
+
+     mpz_t vec[20];
+
+   "Rational number" means a multiple precision fraction.  The C data
+type for these fractions is 'mpq_t'.  For example:
+
+     mpq_t quotient;
+
+   "Floating point number" or "Float" for short, is an arbitrary
+precision mantissa with a limited precision exponent.  The C data type
+for such objects is 'mpf_t'.  For example:
+
+     mpf_t fp;
+
+   The floating point functions accept and return exponents in the C
+type 'mp_exp_t'.  Currently this is usually a 'long', but on some
+systems it's an 'int' for efficiency.
+
+   A "limb" means the part of a multi-precision number that fits in a
+single machine word.  (We chose this word because a limb of the human
+body is analogous to a digit, only larger, and containing several
+digits.)  Normally a limb is 32 or 64 bits.  The C data type for a limb
+is 'mp_limb_t'.
+
+   Counts of limbs of a multi-precision number represented in the C type
+'mp_size_t'.  Currently this is normally a 'long', but on some systems
+it's an 'int' for efficiency, and on some systems it will be 'long long'
+in the future.
+
+   Counts of bits of a multi-precision number are represented in the C
+type 'mp_bitcnt_t'.  Currently this is always an 'unsigned long', but on
+some systems it will be an 'unsigned long long' in the future.
+
+   "Random state" means an algorithm selection and current state data.
+The C data type for such objects is 'gmp_randstate_t'.  For example:
+
+     gmp_randstate_t rstate;
+
+   Also, in general 'mp_bitcnt_t' is used for bit counts and ranges, and
+'size_t' is used for byte or character counts.
+
+
+File: gmp.info,  Node: Function Classes,  Next: Variable Conventions,  Prev: Nomenclature and Types,  Up: GMP Basics
+
+3.3 Function Classes
+====================
+
+There are six classes of functions in the GMP library:
+
+  1. Functions for signed integer arithmetic, with names beginning with
+     'mpz_'.  The associated type is 'mpz_t'.  There are about 150
+     functions in this class.  (*note Integer Functions::)
+
+  2. Functions for rational number arithmetic, with names beginning with
+     'mpq_'.  The associated type is 'mpq_t'.  There are about 35
+     functions in this class, but the integer functions can be used for
+     arithmetic on the numerator and denominator separately.  (*note
+     Rational Number Functions::)
+
+  3. Functions for floating-point arithmetic, with names beginning with
+     'mpf_'.  The associated type is 'mpf_t'.  There are about 70
+     functions is this class.  (*note Floating-point Functions::)
+
+  4. Fast low-level functions that operate on natural numbers.  These
+     are used by the functions in the preceding groups, and you can also
+     call them directly from very time-critical user programs.  These
+     functions' names begin with 'mpn_'.  The associated type is array
+     of 'mp_limb_t'.  There are about 60 (hard-to-use) functions in this
+     class.  (*note Low-level Functions::)
+
+  5. Miscellaneous functions.  Functions for setting up custom
+     allocation and functions for generating random numbers.  (*note
+     Custom Allocation::, and *note Random Number Functions::)
+
+
+File: gmp.info,  Node: Variable Conventions,  Next: Parameter Conventions,  Prev: Function Classes,  Up: GMP Basics
+
+3.4 Variable Conventions
+========================
+
+GMP functions generally have output arguments before input arguments.
+This notation is by analogy with the assignment operator.
+
+   GMP lets you use the same variable for both input and output in one
+call.  For example, the main function for integer multiplication,
+'mpz_mul', can be used to square 'x' and put the result back in 'x' with
+
+     mpz_mul (x, x, x);
+
+   Before you can assign to a GMP variable, you need to initialize it by
+calling one of the special initialization functions.  When you're done
+with a variable, you need to clear it out, using one of the functions
+for that purpose.  Which function to use depends on the type of
+variable.  See the chapters on integer functions, rational number
+functions, and floating-point functions for details.
+
+   A variable should only be initialized once, or at least cleared
+between each initialization.  After a variable has been initialized, it
+may be assigned to any number of times.
+
+   For efficiency reasons, avoid excessive initializing and clearing.
+In general, initialize near the start of a function and clear near the
+end.  For example,
+
+     void
+     foo (void)
+     {
+       mpz_t  n;
+       int    i;
+       mpz_init (n);
+       for (i = 1; i < 100; i++)
+         {
+           mpz_mul (n, ...);
+           mpz_fdiv_q (n, ...);
+           ...
+         }
+       mpz_clear (n);
+     }
+
+   GMP types like 'mpz_t' are implemented as one-element arrays of
+certain structures.  Declaring a variable creates an object with the
+fields GMP needs, but variables are normally manipulated by using the
+pointer to the object.  For both behavior and efficiency reasons, it is
+discouraged to make copies of the GMP object itself (either directly or
+via aggregate objects containing such GMP objects).  If copies are done,
+all of them must be used read-only; using a copy as the output of some
+function will invalidate all the other copies.  Note that the actual
+fields in each 'mpz_t' etc are for internal use only and should not be
+accessed directly by code that expects to be compatible with future GMP
+releases.
+
+
+File: gmp.info,  Node: Parameter Conventions,  Next: Memory Management,  Prev: Variable Conventions,  Up: GMP Basics
+
+3.5 Parameter Conventions
+=========================
+
+When a GMP variable is used as a function parameter, it's effectively a
+call-by-reference, meaning that when the function stores a value there
+it will change the original in the caller.  Parameters which are
+input-only can be designated 'const' to provoke a compiler error or
+warning on attempting to modify them.
+
+   When a function is going to return a GMP result, it should designate
+a parameter that it sets, like the library functions do.  More than one
+value can be returned by having more than one output parameter, again
+like the library functions.  A 'return' of an 'mpz_t' etc doesn't return
+the object, only a pointer, and this is almost certainly not what's
+wanted.
+
+   Here's an example accepting an 'mpz_t' parameter, doing a
+calculation, and storing the result to the indicated parameter.
+
+     void
+     foo (mpz_t result, const mpz_t param, unsigned long n)
+     {
+       unsigned long  i;
+       mpz_mul_ui (result, param, n);
+       for (i = 1; i < n; i++)
+         mpz_add_ui (result, result, i*7);
+     }
+
+     int
+     main (void)
+     {
+       mpz_t  r, n;
+       mpz_init (r);
+       mpz_init_set_str (n, "123456", 0);
+       foo (r, n, 20L);
+       gmp_printf ("%Zd\n", r);
+       return 0;
+     }
+
+   Our function 'foo' works even if its caller passes the same variable
+for 'param' and 'result', just like the library functions.  But
+sometimes it's tricky to make that work, and an application might not
+want to bother supporting that sort of thing.
+
+   Since GMP types are implemented as one-element arrays, using a GMP
+variable as a parameter passes a pointer to the object.  Hence the
+call-by-reference.
+
+
+File: gmp.info,  Node: Memory Management,  Next: Reentrancy,  Prev: Parameter Conventions,  Up: GMP Basics
+
+3.6 Memory Management
+=====================
+
+The GMP types like 'mpz_t' are small, containing only a couple of sizes,
+and pointers to allocated data.  Once a variable is initialized, GMP
+takes care of all space allocation.  Additional space is allocated
+whenever a variable doesn't have enough.
+
+   'mpz_t' and 'mpq_t' variables never reduce their allocated space.
+Normally this is the best policy, since it avoids frequent reallocation.
+Applications that need to return memory to the heap at some particular
+point can use 'mpz_realloc2', or clear variables no longer needed.
+
+   'mpf_t' variables, in the current implementation, use a fixed amount
+of space, determined by the chosen precision and allocated at
+initialization, so their size doesn't change.
+
+   All memory is allocated using 'malloc' and friends by default, but
+this can be changed, see *note Custom Allocation::.  Temporary memory on
+the stack is also used (via 'alloca'), but this can be changed at
+build-time if desired, see *note Build Options::.
+
+
+File: gmp.info,  Node: Reentrancy,  Next: Useful Macros and Constants,  Prev: Memory Management,  Up: GMP Basics
+
+3.7 Reentrancy
+==============
+
+GMP is reentrant and thread-safe, with some exceptions:
+
+   * If configured with '--enable-alloca=malloc-notreentrant' (or with
+     '--enable-alloca=notreentrant' when 'alloca' is not available),
+     then naturally GMP is not reentrant.
+
+   * 'mpf_set_default_prec' and 'mpf_init' use a global variable for the
+     selected precision.  'mpf_init2' can be used instead, and in the
+     C++ interface an explicit precision to the 'mpf_class' constructor.
+
+   * 'mpz_random' and the other old random number functions use a global
+     random state and are hence not reentrant.  The newer random number
+     functions that accept a 'gmp_randstate_t' parameter can be used
+     instead.
+
+   * 'gmp_randinit' (obsolete) returns an error indication through a
+     global variable, which is not thread safe.  Applications are
+     advised to use 'gmp_randinit_default' or 'gmp_randinit_lc_2exp'
+     instead.
+
+   * 'mp_set_memory_functions' uses global variables to store the
+     selected memory allocation functions.
+
+   * If the memory allocation functions set by a call to
+     'mp_set_memory_functions' (or 'malloc' and friends by default) are
+     not reentrant, then GMP will not be reentrant either.
+
+   * If the standard I/O functions such as 'fwrite' are not reentrant
+     then the GMP I/O functions using them will not be reentrant either.
+
+   * It's safe for two threads to read from the same GMP variable
+     simultaneously, but it's not safe for one to read while another
+     might be writing, nor for two threads to write simultaneously.
+     It's not safe for two threads to generate a random number from the
+     same 'gmp_randstate_t' simultaneously, since this involves an
+     update of that variable.

+This version of GMP is upwardly binary compatible with all 5.x, 4.x, and

+versions, with the following exceptions.
+
+   * 'mpn_gcd' had its source arguments swapped as of GMP 3.0, for
+     consistency with other 'mpn' functions.

+3.10 Demonstration programs
+===========================
+
+The 'demos' subdirectory has some sample programs using GMP.  These
+aren't built or installed, but there's a 'Makefile' with rules for them.
+For instance,
+
+     make pexpr
+     ./pexpr 68^975+10
+
+The following programs are provided
+
+   * 'pexpr' is an expression evaluator, the program used on the GMP web
+     page.
+   * The 'calc' subdirectory has a similar but simpler evaluator using
+     'lex' and 'yacc'.
+   * The 'expr' subdirectory is yet another expression evaluator, a
+     library designed for ease of use within a C program.  See
+     'demos/expr/README' for more information.
+   * 'factorize' is a Pollard-Rho factorization program.
+   * 'isprime' is a command-line interface to the 'mpz_probab_prime_p'
+     function.
+   * 'primes' counts or lists primes in an interval, using a sieve.
+   * 'qcn' is an example use of 'mpz_kronecker_ui' to estimate quadratic
+     class numbers.
+   * The 'perl' subdirectory is a comprehensive perl interface to GMP.
+     See 'demos/perl/INSTALL' for more information.  Documentation is in
+     POD format in 'demos/perl/GMP.pm'.
+
+   As an aside, consideration has been given at various times to some
+sort of expression evaluation within the main GMP library.  Going beyond
+something minimal quickly leads to matters like user-defined functions,
+looping, fixnums for control variables, etc, which are considered
+outside the scope of GMP (much closer to language interpreters or
+compilers, *Note Language Bindings::.)  Something simple for program
+input convenience may yet be a possibility, a combination of the 'expr'
+demo and the 'pexpr' tree back-end perhaps.  But for now the above
+evaluators are offered as illustrations.

+
+3.11 Efficiency
+===============
+
+Small Operands
+     On small operands, the time for function call overheads and memory
+     allocation can be significant in comparison to actual calculation.
+     This is unavoidable in a general purpose variable precision
+     library, although GMP attempts to be as efficient as it can on both
+     large and small operands.
+
+Static Linking
+     On some CPUs, in particular the x86s, the static 'libgmp.a' should
+     be used for maximum speed, since the PIC code in the shared
+     'libgmp.so' will have a small overhead on each function call and
+     global data address.  For many programs this will be insignificant,
+     but for long calculations there's a gain to be had.
+
+Initializing and Clearing
+     Avoid excessive initializing and clearing of variables, since this
+     can be quite time consuming, especially in comparison to otherwise
+     fast operations like addition.
+
+     A language interpreter might want to keep a free list or stack of
+     initialized variables ready for use.  It should be possible to
+     integrate something like that with a garbage collector too.
+
+Reallocations
+     An 'mpz_t' or 'mpq_t' variable used to hold successively increasing
+     values will have its memory repeatedly 'realloc'ed, which could be
+     quite slow or could fragment memory, depending on the C library.
+     If an application can estimate the final size then 'mpz_init2' or
+     'mpz_realloc2' can be called to allocate the necessary space from
+     the beginning (*note Initializing Integers::).
+
+     It doesn't matter if a size set with 'mpz_init2' or 'mpz_realloc2'
+     is too small, since all functions will do a further reallocation if
+     necessary.  Badly overestimating memory required will waste space
+     though.
+
+'2exp' Functions
+     It's up to an application to call functions like 'mpz_mul_2exp'
+     when appropriate.  General purpose functions like 'mpz_mul' make no
+     attempt to identify powers of two or other special forms, because
+     such inputs will usually be very rare and testing every time would
+     be wasteful.
+
+'ui' and 'si' Functions
+     The 'ui' functions and the small number of 'si' functions exist for
+     convenience and should be used where applicable.  But if for
+     example an 'mpz_t' contains a value that fits in an 'unsigned long'
+     there's no need extract it and call a 'ui' function, just use the
+     regular 'mpz' function.
+
+In-Place Operations
+     'mpz_abs', 'mpq_abs', 'mpf_abs', 'mpz_neg', 'mpq_neg' and 'mpf_neg'
+     are fast when used for in-place operations like 'mpz_abs(x,x)',
+     since in the current implementation only a single field of 'x'
+     needs changing.  On suitable compilers (GCC for instance) this is
+     inlined too.
+
+     'mpz_add_ui', 'mpz_sub_ui', 'mpf_add_ui' and 'mpf_sub_ui' benefit
+     from an in-place operation like 'mpz_add_ui(x,x,y)', since usually
+     only one or two limbs of 'x' will need to be changed.  The same
+     applies to the full precision 'mpz_add' etc if 'y' is small.  If
+     'y' is big then cache locality may be helped, but that's all.
+
+     'mpz_mul' is currently the opposite, a separate destination is
+     slightly better.  A call like 'mpz_mul(x,x,y)' will, unless 'y' is
+     only one limb, make a temporary copy of 'x' before forming the
+     result.  Normally that copying will only be a tiny fraction of the
+     time for the multiply, so this is not a particularly important
+     consideration.
+
+     'mpz_set', 'mpq_set', 'mpq_set_num', 'mpf_set', etc, make no
+     attempt to recognise a copy of something to itself, so a call like
+     'mpz_set(x,x)' will be wasteful.  Naturally that would never be
+     written deliberately, but if it might arise from two pointers to
+     the same object then a test to avoid it might be desirable.
+
+          if (x != y)
+            mpz_set (x, y);
+
+     Note that it's never worth introducing extra 'mpz_set' calls just
+     to get in-place operations.  If a result should go to a particular
+     variable then just direct it there and let GMP take care of data
+     movement.
+
+Divisibility Testing (Small Integers)
+     'mpz_divisible_ui_p' and 'mpz_congruent_ui_p' are the best
+     functions for testing whether an 'mpz_t' is divisible by an
+     individual small integer.  They use an algorithm which is faster
+     than 'mpz_tdiv_ui', but which gives no useful information about the
+     actual remainder, only whether it's zero (or a particular value).
+
+     However when testing divisibility by several small integers, it's
+     best to take a remainder modulo their product, to save
+     multi-precision operations.  For instance to test whether a number
+     is divisible by any of 23, 29 or 31 take a remainder modulo
+     23*29*31 = 20677 and then test that.
+
+     The division functions like 'mpz_tdiv_q_ui' which give a quotient
+     as well as a remainder are generally a little slower than the
+     remainder-only functions like 'mpz_tdiv_ui'.  If the quotient is
+     only rarely wanted then it's probably best to just take a remainder
+     and then go back and calculate the quotient if and when it's wanted
+     ('mpz_divexact_ui' can be used if the remainder is zero).
+
+Rational Arithmetic
+     The 'mpq' functions operate on 'mpq_t' values with no common
+     factors in the numerator and denominator.  Common factors are
+     checked-for and cast out as necessary.  In general, cancelling
+     factors every time is the best approach since it minimizes the
+     sizes for subsequent operations.
+
+     However, applications that know something about the factorization
+     of the values they're working with might be able to avoid some of
+     the GCDs used for canonicalization, or swap them for divisions.
+     For example when multiplying by a prime it's enough to check for
+     factors of it in the denominator instead of doing a full GCD.  Or
+     when forming a big product it might be known that very little
+     cancellation will be possible, and so canonicalization can be left
+     to the end.
+
+     The 'mpq_numref' and 'mpq_denref' macros give access to the
+     numerator and denominator to do things outside the scope of the
+     supplied 'mpq' functions.  *Note Applying Integer Functions::.
+
+     The canonical form for rationals allows mixed-type 'mpq_t' and
+     integer additions or subtractions to be done directly with
+     multiples of the denominator.  This will be somewhat faster than
+     'mpq_add'.  For example,
+
+          /* mpq increment */
+          mpz_add (mpq_numref(q), mpq_numref(q), mpq_denref(q));
+
+          /* mpq += unsigned long */
+          mpz_addmul_ui (mpq_numref(q), mpq_denref(q), 123UL);
+
+          /* mpq -= mpz */
+          mpz_submul (mpq_numref(q), mpq_denref(q), z);
+
+Number Sequences
+     Functions like 'mpz_fac_ui', 'mpz_fib_ui' and 'mpz_bin_uiui' are
+     designed for calculating isolated values.  If a range of values is
+     wanted it's probably best to call to get a starting point and
+     iterate from there.
+
+Text Input/Output
+     Hexadecimal or octal are suggested for input or output in text
+     form.  Power-of-2 bases like these can be converted much more
+     efficiently than other bases, like decimal.  For big numbers
+     there's usually nothing of particular interest to be seen in the
+     digits, so the base doesn't matter much.
+
+     Maybe we can hope octal will one day become the normal base for
+     everyday use, as proposed by King Charles XII of Sweden and later
+     reformers.

+
+3.12 Debugging
+==============
+
+Stack Overflow
+     Depending on the system, a segmentation violation or bus error
+     might be the only indication of stack overflow.  See
+     '--enable-alloca' choices in *note Build Options::, for how to
+     address this.
+
+     In new enough versions of GCC, '-fstack-check' may be able to
+     ensure an overflow is recognised by the system before too much
+     damage is done, or '-fstack-limit-symbol' or
+     '-fstack-limit-register' may be able to add checking if the system
+     itself doesn't do any (*note Options for Code Generation: (gcc)Code
+     Gen Options.).  These options must be added to the 'CFLAGS' used in
+     the GMP build (*note Build Options::), adding them just to an
+     application will have no effect.  Note also they're a slowdown,
+     adding overhead to each function call and each stack allocation.
+
+Heap Problems
+     The most likely cause of application problems with GMP is heap
+     corruption.  Failing to 'init' GMP variables will have
+     unpredictable effects, and corruption arising elsewhere in a
+     program may well affect GMP.  Initializing GMP variables more than
+     once or failing to clear them will cause memory leaks.
+
+     In all such cases a 'malloc' debugger is recommended.  On a GNU or
+     BSD system the standard C library 'malloc' has some diagnostic
+     facilities, see *note Allocation Debugging: (libc)Allocation
+     Debugging, or 'man 3 malloc'.  Other possibilities, in no
+     particular order, include
+
+          <http://cs.ecs.baylor.edu/~donahoo/tools/ccmalloc/>
+          <http://dmalloc.com/>
+          <https://wiki.gnome.org/Apps/MemProf>
+
+     The GMP default allocation routines in 'memory.c' also have a
+     simple sentinel scheme which can be enabled with '#define DEBUG' in
+     that file.  This is mainly designed for detecting buffer overruns
+     during GMP development, but might find other uses.
+
+Stack Backtraces
+     On some systems the compiler options GMP uses by default can
+     interfere with debugging.  In particular on x86 and 68k systems
+     '-fomit-frame-pointer' is used and this generally inhibits stack
+     backtracing.  Recompiling without such options may help while
+     debugging, though the usual caveats about it potentially moving a
+     memory problem or hiding a compiler bug will apply.
+
+GDB, the GNU Debugger
+     A sample '.gdbinit' is included in the distribution, showing how to
+     call some undocumented dump functions to print GMP variables from
+     within GDB.  Note that these functions shouldn't be used in final
+     application code since they're undocumented and may be subject to
+     incompatible changes in future versions of GMP.
+
+Source File Paths
+     GMP has multiple source files with the same name, in different
+     directories.  For example 'mpz', 'mpq' and 'mpf' each have an
+     'init.c'.  If the debugger can't already determine the right one it
+     may help to build with absolute paths on each C file.  One way to
+     do that is to use a separate object directory with an absolute path
+     to the source directory.
+
+          cd /my/build/dir
+          /my/source/dir/gmp-6.2.0/configure
+
+     This works via 'VPATH', and might require GNU 'make'.  Alternately
+     it might be possible to change the '.c.lo' rules appropriately.
+
+Assertion Checking
+     The build option '--enable-assert' is available to add some
+     consistency checks to the library (see *note Build Options::).
+     These are likely to be of limited value to most applications.
+     Assertion failures are just as likely to indicate memory corruption
+     as a library or compiler bug.
+
+     Applications using the low-level 'mpn' functions, however, will
+     benefit from '--enable-assert' since it adds checks on the
+     parameters of most such functions, many of which have subtle
+     restrictions on their usage.  Note however that only the generic C
+     code has checks, not the assembly code, so '--disable-assembly'
+     should be used for maximum checking.
+
+Temporary Memory Checking
+     The build option '--enable-alloca=debug' arranges that each block
+     of temporary memory in GMP is allocated with a separate call to
+     'malloc' (or the allocation function set with
+     'mp_set_memory_functions').
+
+     This can help a malloc debugger detect accesses outside the
+     intended bounds, or detect memory not released.  In a normal build,
+     on the other hand, temporary memory is allocated in blocks which
+     GMP divides up for its own use, or may be allocated with a compiler
+     builtin 'alloca' which will go nowhere near any malloc debugger
+     hooks.
+
+Maximum Debuggability
+     To summarize the above, a GMP build for maximum debuggability would
+     be
+
+          ./configure --disable-shared --enable-assert \
+            --enable-alloca=debug --disable-assembly CFLAGS=-g
+
+     For C++, add '--enable-cxx CXXFLAGS=-g'.
+
+Checker
+     The GCC checker (<https://savannah.nongnu.org/projects/checker/>)
+     can be used with GMP.  It contains a stub library which means GMP
+     applications compiled with checker can use a normal GMP build.
+
+     A build of GMP with checking within GMP itself can be made.  This
+     will run very very slowly.  On GNU/Linux for example,
+
+          ./configure --disable-assembly CC=checkergcc
+
+     '--disable-assembly' must be used, since the GMP assembly code
+     doesn't support the checking scheme.  The GMP C++ features cannot
+     be used, since current versions of checker (0.9.9.1) don't yet
+     support the standard C++ library.
+
+Valgrind
+     Valgrind (<http://valgrind.org/>) is a memory checker for x86, ARM,
+     MIPS, PowerPC, and S/390.  It translates and emulates machine
+     instructions to do strong checks for uninitialized data (at the
+     level of individual bits), memory accesses through bad pointers,
+     and memory leaks.
+
+     Valgrind does not always support every possible instruction, in
+     particular ones recently added to an ISA. Valgrind might therefore
+     be incompatible with a recent GMP or even a less recent GMP which
+     is compiled using a recent GCC.
+
+     GMP's assembly code sometimes promotes a read of the limbs to some
+     larger size, for efficiency.  GMP will do this even at the start
+     and end of a multilimb operand, using naturally aligned operations
+     on the larger type.  This may lead to benign reads outside of
+     allocated areas, triggering complaints from Valgrind.  Valgrind's
+     option '--partial-loads-ok=yes' should help.
+
+Other Problems
+     Any suspected bug in GMP itself should be isolated to make sure
+     it's not an application problem, see *note Reporting Bugs::.

+
+3.13 Profiling
+==============
+
+Running a program under a profiler is a good way to find where it's
+spending most time and where improvements can be best sought.  The
+profiling choices for a GMP build are as follows.
+
+'--disable-profiling'
+     The default is to add nothing special for profiling.
+
+     It should be possible to just compile the mainline of a program
+     with '-p' and use 'prof' to get a profile consisting of timer-based
+     sampling of the program counter.  Most of the GMP assembly code has
+     the necessary symbol information.
+
+     This approach has the advantage of minimizing interference with
+     normal program operation, but on most systems the resolution of the
+     sampling is quite low (10 milliseconds for instance), requiring
+     long runs to get accurate information.
+
+'--enable-profiling=prof'
+     Build with support for the system 'prof', which means '-p' added to
+     the 'CFLAGS'.
+
+     This provides call counting in addition to program counter
+     sampling, which allows the most frequently called routines to be
+     identified, and an average time spent in each routine to be
+     determined.
+
+     The x86 assembly code has support for this option, but on other
+     processors the assembly routines will be as if compiled without
+     '-p' and therefore won't appear in the call counts.
+
+     On some systems, such as GNU/Linux, '-p' in fact means '-pg' and in
+     this case '--enable-profiling=gprof' described below should be used
+     instead.
+
+'--enable-profiling=gprof'
+     Build with support for 'gprof', which means '-pg' added to the
+     'CFLAGS'.
+
+     This provides call graph construction in addition to call counting
+     and program counter sampling, which makes it possible to count
+     calls coming from different locations.  For example the number of
+     calls to 'mpn_mul' from 'mpz_mul' versus the number from 'mpf_mul'.
+     The program counter sampling is still flat though, so only a total
+     time in 'mpn_mul' would be accumulated, not a separate amount for
+     each call site.
+
+     The x86 assembly code has support for this option, but on other
+     processors the assembly routines will be as if compiled without
+     '-pg' and therefore not be included in the call counts.
+
+     On x86 and m68k systems '-pg' and '-fomit-frame-pointer' are
+     incompatible, so the latter is omitted from the default flags in
+     that case, which might result in poorer code generation.
+
+     Incidentally, it should be possible to use the 'gprof' program with
+     a plain '--enable-profiling=prof' build.  But in that case only the
+     'gprof -p' flat profile and call counts can be expected to be
+     valid, not the 'gprof -q' call graph.
+
+'--enable-profiling=instrument'
+     Build with the GCC option '-finstrument-functions' added to the
+     'CFLAGS' (*note Options for Code Generation: (gcc)Code Gen
+     Options.).
+
+     This inserts special instrumenting calls at the start and end of
+     each function, allowing exact timing and full call graph
+     construction.
+
+     This instrumenting is not normally a standard system feature and
+     will require support from an external library, such as
+
+          <https://sourceforge.net/projects/fnccheck/>
+
+     This should be included in 'LIBS' during the GMP configure so that
+     test programs will link.  For example,
+
+          ./configure --enable-profiling=instrument LIBS=-lfc
+
+     On a GNU system the C library provides dummy instrumenting
+     functions, so programs compiled with this option will link.  In
+     this case it's only necessary to ensure the correct library is
+     added when linking an application.
+
+     The x86 assembly code supports this option, but on other processors
+     the assembly routines will be as if compiled without
+     '-finstrument-functions' meaning time spent in them will
+     effectively be attributed to their caller.

+
+3.14 Autoconf
+=============
+
+Autoconf based applications can easily check whether GMP is installed.
+The only thing to be noted is that GMP library symbols from version 3
+onwards have prefixes like '__gmpz'.  The following therefore would be a
+simple test,
+
+     AC_CHECK_LIB(gmp, __gmpz_init)
+
+   This just uses the default 'AC_CHECK_LIB' actions for found or not
+found, but an application that must have GMP would want to generate an
+error if not found.  For example,
+
+     AC_CHECK_LIB(gmp, __gmpz_init, ,
+       [AC_MSG_ERROR([GNU MP not found, see https://gmplib.org/])])
+
+   If functions added in some particular version of GMP are required,
+then one of those can be used when checking.  For example 'mpz_mul_si'
+was added in GMP 3.1,
+
+     AC_CHECK_LIB(gmp, __gmpz_mul_si, ,
+       [AC_MSG_ERROR(
+       [GNU MP not found, or not 3.1 or up, see https://gmplib.org/])])
+
+   An alternative would be to test the version number in 'gmp.h' using
+say 'AC_EGREP_CPP'.  That would make it possible to test the exact
+version, if some particular sub-minor release is known to be necessary.
+
+   In general it's recommended that applications should simply demand a
+new enough GMP rather than trying to provide supplements for features
+not available in past versions.
+
+   Occasionally an application will need or want to know the size of a
+type at configuration or preprocessing time, not just with 'sizeof' in
+the code.  This can be done in the normal way with 'mp_limb_t' etc, but
+GMP 4.0 or up is best for this, since prior versions needed certain '-D'
+defines on systems using a 'long long' limb.  The following would suit
+Autoconf 2.50 or up,
+
+     AC_CHECK_SIZEOF(mp_limb_t, , [#include <gmp.h>])

+
+5.1 Initialization Functions
+============================
+
+The functions for integer arithmetic assume that all integer objects are
+initialized.  You do that by calling the function 'mpz_init'.  For
+example,
+
+     {
+       mpz_t integ;
+       mpz_init (integ);
+       ...
+       mpz_add (integ, ...);
+       ...
+       mpz_sub (integ, ...);
+
+       /* Unless the program is about to exit, do ... */
+       mpz_clear (integ);
+     }
+
+   As you can see, you can store new values any number of times, once an
+object is initialized.
+
+ -- Function: void mpz_init (mpz_t X)
+     Initialize X, and set its value to 0.
+
+ -- Function: void mpz_inits (mpz_t X, ...)
+     Initialize a NULL-terminated list of 'mpz_t' variables, and set
+     their values to 0.
+
+ -- Function: void mpz_init2 (mpz_t X, mp_bitcnt_t N)
+     Initialize X, with space for N-bit numbers, and set its value to 0.
+     Calling this function instead of 'mpz_init' or 'mpz_inits' is never
+     necessary; reallocation is handled automatically by GMP when
+     needed.
+
+     While N defines the initial space, X will grow automatically in the
+     normal way, if necessary, for subsequent values stored.
+     'mpz_init2' makes it possible to avoid such reallocations if a
+     maximum size is known in advance.
+
+     In preparation for an operation, GMP often allocates one limb more
+     than ultimately needed.  To make sure GMP will not perform
+     reallocation for X, you need to add the number of bits in
+     'mp_limb_t' to N.
+
+ -- Function: void mpz_clear (mpz_t X)
+     Free the space occupied by X.  Call this function for all 'mpz_t'
+     variables when you are done with them.
+
+ -- Function: void mpz_clears (mpz_t X, ...)
+     Free the space occupied by a NULL-terminated list of 'mpz_t'
+     variables.
+
+ -- Function: void mpz_realloc2 (mpz_t X, mp_bitcnt_t N)
+     Change the space allocated for X to N bits.  The value in X is
+     preserved if it fits, or is set to 0 if not.
+
+     Calling this function is never necessary; reallocation is handled
+     automatically by GMP when needed.  But this function can be used to
+     increase the space for a variable in order to avoid repeated
+     automatic reallocations, or to decrease it to give memory back to
+     the heap.

+
+5.2 Assignment Functions
+========================
+
+These functions assign new values to already initialized integers (*note
+Initializing Integers::).
+
+ -- Function: void mpz_set (mpz_t ROP, const mpz_t OP)
+ -- Function: void mpz_set_ui (mpz_t ROP, unsigned long int OP)
+ -- Function: void mpz_set_si (mpz_t ROP, signed long int OP)
+ -- Function: void mpz_set_d (mpz_t ROP, double OP)
+ -- Function: void mpz_set_q (mpz_t ROP, const mpq_t OP)
+ -- Function: void mpz_set_f (mpz_t ROP, const mpf_t OP)
+     Set the value of ROP from OP.
+
+     'mpz_set_d', 'mpz_set_q' and 'mpz_set_f' truncate OP to make it an
+     integer.
+
+ -- Function: int mpz_set_str (mpz_t ROP, const char *STR, int BASE)
+     Set the value of ROP from STR, a null-terminated C string in base
+     BASE.  White space is allowed in the string, and is simply ignored.
+
+     The BASE may vary from 2 to 62, or if BASE is 0, then the leading
+     characters are used: '0x' and '0X' for hexadecimal, '0b' and '0B'
+     for binary, '0' for octal, or decimal otherwise.
+
+     For bases up to 36, case is ignored; upper-case and lower-case
+     letters have the same value.  For bases 37 to 62, upper-case letter
+     represent the usual 10..35 while lower-case letter represent
+     36..61.
+
+     This function returns 0 if the entire string is a valid number in
+     base BASE.  Otherwise it returns -1.
+
+ -- Function: void mpz_swap (mpz_t ROP1, mpz_t ROP2)
+     Swap the values ROP1 and ROP2 efficiently.
+

+
+5.3 Combined Initialization and Assignment Functions
+====================================================
+
+For convenience, GMP provides a parallel series of initialize-and-set
+functions which initialize the output and then store the value there.
+These functions' names have the form 'mpz_init_set...'
+
+   Here is an example of using one:
+
+     {
+       mpz_t pie;
+       mpz_init_set_str (pie, "3141592653589793238462643383279502884", 10);
+       ...
+       mpz_sub (pie, ...);
+       ...
+       mpz_clear (pie);
+     }
+
+Once the integer has been initialized by any of the 'mpz_init_set...'
+functions, it can be used as the source or destination operand for the
+ordinary integer functions.  Don't use an initialize-and-set function on
+a variable already initialized!
+
+ -- Function: void mpz_init_set (mpz_t ROP, const mpz_t OP)
+ -- Function: void mpz_init_set_ui (mpz_t ROP, unsigned long int OP)
+ -- Function: void mpz_init_set_si (mpz_t ROP, signed long int OP)
+ -- Function: void mpz_init_set_d (mpz_t ROP, double OP)
+     Initialize ROP with limb space and set the initial numeric value
+     from OP.
+
+ -- Function: int mpz_init_set_str (mpz_t ROP, const char *STR, int
+          BASE)
+     Initialize ROP and set its value like 'mpz_set_str' (see its
+     documentation above for details).
+
+     If the string is a correct base BASE number, the function returns
+     0; if an error occurs it returns -1.  ROP is initialized even if an
+     error occurs.  (I.e., you have to call 'mpz_clear' for it.)

+
+5.4 Conversion Functions
+========================
+
+This section describes functions for converting GMP integers to standard
+C types.  Functions for converting _to_ GMP integers are described in
+*note Assigning Integers:: and *note I/O of Integers::.
+
+ -- Function: unsigned long int mpz_get_ui (const mpz_t OP)
+     Return the value of OP as an 'unsigned long'.
+
+     If OP is too big to fit an 'unsigned long' then just the least
+     significant bits that do fit are returned.  The sign of OP is
+     ignored, only the absolute value is used.
+
+ -- Function: signed long int mpz_get_si (const mpz_t OP)
+     If OP fits into a 'signed long int' return the value of OP.
+     Otherwise return the least significant part of OP, with the same
+     sign as OP.
+
+     If OP is too big to fit in a 'signed long int', the returned result
+     is probably not very useful.  To find out if the value will fit,
+     use the function 'mpz_fits_slong_p'.
+
+ -- Function: double mpz_get_d (const mpz_t OP)
+     Convert OP to a 'double', truncating if necessary (i.e. rounding
+     towards zero).
+
+     If the exponent from the conversion is too big, the result is
+     system dependent.  An infinity is returned where available.  A
+     hardware overflow trap may or may not occur.
+
+ -- Function: double mpz_get_d_2exp (signed long int *EXP, const mpz_t
+          OP)
+     Convert OP to a 'double', truncating if necessary (i.e. rounding
+     towards zero), and returning the exponent separately.
+
+     The return value is in the range 0.5<=abs(D)<1 and the exponent is
+     stored to '*EXP'.  D * 2^EXP is the (truncated) OP value.  If OP is
+     zero, the return is 0.0 and 0 is stored to '*EXP'.
+
+     This is similar to the standard C 'frexp' function (*note
+     (libc)Normalization Functions::).
+
+ -- Function: char * mpz_get_str (char *STR, int BASE, const mpz_t OP)
+     Convert OP to a string of digits in base BASE.  The base argument
+     may vary from 2 to 62 or from -2 to -36.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     If STR is 'NULL', the result string is allocated using the current
+     allocation function (*note Custom Allocation::).  The block will be
+     'strlen(str)+1' bytes, that being exactly enough for the string and
+     null-terminator.
+
+     If STR is not 'NULL', it should point to a block of storage large
+     enough for the result, that being 'mpz_sizeinbase (OP, BASE) + 2'.
+     The two extra bytes are for a possible minus sign, and the
+     null-terminator.
+
+     A pointer to the result string is returned, being either the
+     allocated block, or the given STR.

+========================
+
+ -- Function: void mpz_add (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+ -- Function: void mpz_add_ui (mpz_t ROP, const mpz_t OP1, unsigned long
+          int OP2)
+     Set ROP to OP1 + OP2.
+
+ -- Function: void mpz_sub (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+ -- Function: void mpz_sub_ui (mpz_t ROP, const mpz_t OP1, unsigned long
+          int OP2)
+ -- Function: void mpz_ui_sub (mpz_t ROP, unsigned long int OP1, const
+          mpz_t OP2)
+     Set ROP to OP1 - OP2.
+
+ -- Function: void mpz_mul (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+ -- Function: void mpz_mul_si (mpz_t ROP, const mpz_t OP1, long int OP2)
+ -- Function: void mpz_mul_ui (mpz_t ROP, const mpz_t OP1, unsigned long
+          int OP2)
+     Set ROP to OP1 times OP2.
+
+ -- Function: void mpz_addmul (mpz_t ROP, const mpz_t OP1, const mpz_t
+          OP2)
+ -- Function: void mpz_addmul_ui (mpz_t ROP, const mpz_t OP1, unsigned
+          long int OP2)
+     Set ROP to ROP + OP1 times OP2.
+
+ -- Function: void mpz_submul (mpz_t ROP, const mpz_t OP1, const mpz_t
+          OP2)
+ -- Function: void mpz_submul_ui (mpz_t ROP, const mpz_t OP1, unsigned
+          long int OP2)
+     Set ROP to ROP - OP1 times OP2.
+
+ -- Function: void mpz_mul_2exp (mpz_t ROP, const mpz_t OP1, mp_bitcnt_t
+          OP2)
+     Set ROP to OP1 times 2 raised to OP2.  This operation can also be
+     defined as a left shift by OP2 bits.
+
+ -- Function: void mpz_neg (mpz_t ROP, const mpz_t OP)
+     Set ROP to -OP.
+
+ -- Function: void mpz_abs (mpz_t ROP, const mpz_t OP)
+     Set ROP to the absolute value of OP.

+
+5.6 Division Functions
+======================
+
+Division is undefined if the divisor is zero.  Passing a zero divisor to
+the division or modulo functions (including the modular powering
+functions 'mpz_powm' and 'mpz_powm_ui'), will cause an intentional
+division by zero.  This lets a program handle arithmetic exceptions in
+these functions the same way as for normal C 'int' arithmetic.
+
+ -- Function: void mpz_cdiv_q (mpz_t Q, const mpz_t N, const mpz_t D)
+ -- Function: void mpz_cdiv_r (mpz_t R, const mpz_t N, const mpz_t D)
+ -- Function: void mpz_cdiv_qr (mpz_t Q, mpz_t R, const mpz_t N, const

+ -- Function: void mpz_fdiv_r_2exp (mpz_t R, const mpz_t N,
+          mp_bitcnt_t B)
+
+ -- Function: void mpz_tdiv_q (mpz_t Q, const mpz_t N, const mpz_t D)
+ -- Function: void mpz_tdiv_r (mpz_t R, const mpz_t N, const mpz_t D)
+ -- Function: void mpz_tdiv_qr (mpz_t Q, mpz_t R, const mpz_t N, const
+          mpz_t D)
+
+ -- Function: unsigned long int mpz_tdiv_q_ui (mpz_t Q, const mpz_t N,
+          unsigned long int D)
+ -- Function: unsigned long int mpz_tdiv_r_ui (mpz_t R, const mpz_t N,
+          unsigned long int D)
+ -- Function: unsigned long int mpz_tdiv_qr_ui (mpz_t Q, mpz_t R,

+ -- Function: unsigned long int mpz_tdiv_ui (const mpz_t N,
+          unsigned long int D)
+
+ -- Function: void mpz_tdiv_q_2exp (mpz_t Q, const mpz_t N,
+          mp_bitcnt_t B)
+ -- Function: void mpz_tdiv_r_2exp (mpz_t R, const mpz_t N,
+          mp_bitcnt_t B)
+
+
+     Divide N by D, forming a quotient Q and/or remainder R.  For the
+     '2exp' functions, D=2^B.  The rounding is in three styles, each
+     suiting different applications.
+
+        * 'cdiv' rounds Q up towards +infinity, and R will have the
+          opposite sign to D.  The 'c' stands for "ceil".
+
+        * 'fdiv' rounds Q down towards -infinity, and R will have the
+          same sign as D.  The 'f' stands for "floor".
+
+        * 'tdiv' rounds Q towards zero, and R will have the same sign as
+          N.  The 't' stands for "truncate".
+
+     In all cases Q and R will satisfy N=Q*D+R, and R will satisfy
+     0<=abs(R)<abs(D).
+
+     The 'q' functions calculate only the quotient, the 'r' functions
+     only the remainder, and the 'qr' functions calculate both.  Note
+     that for 'qr' the same variable cannot be passed for both Q and R,
+     or results will be unpredictable.
+
+     For the 'ui' variants the return value is the remainder, and in
+     fact returning the remainder is all the 'div_ui' functions do.  For
+     'tdiv' and 'cdiv' the remainder can be negative, so for those the
+     return value is the absolute value of the remainder.
+
+     For the '2exp' variants the divisor is 2^B.  These functions are
+     implemented as right shifts and bit masks, but of course they round
+     the same as the other functions.
+
+     For positive N both 'mpz_fdiv_q_2exp' and 'mpz_tdiv_q_2exp' are
+     simple bitwise right shifts.  For negative N, 'mpz_fdiv_q_2exp' is
+     effectively an arithmetic right shift treating N as twos complement
+     the same as the bitwise logical functions do, whereas
+     'mpz_tdiv_q_2exp' effectively treats N as sign and magnitude.
+
+ -- Function: void mpz_mod (mpz_t R, const mpz_t N, const mpz_t D)
+ -- Function: unsigned long int mpz_mod_ui (mpz_t R, const mpz_t N,
+          unsigned long int D)
+     Set R to N 'mod' D.  The sign of the divisor is ignored; the result
+     is always non-negative.
+
+     'mpz_mod_ui' is identical to 'mpz_fdiv_r_ui' above, returning the
+     remainder as well as setting R.  See 'mpz_fdiv_ui' above if only
+     the return value is wanted.
+
+ -- Function: void mpz_divexact (mpz_t Q, const mpz_t N, const mpz_t D)
+ -- Function: void mpz_divexact_ui (mpz_t Q, const mpz_t N, unsigned
+          long D)
+     Set Q to N/D.  These functions produce correct results only when it
+     is known in advance that D divides N.
+
+     These routines are much faster than the other division functions,
+     and are the best choice when exact division is known to occur, for
+     example reducing a rational to lowest terms.
+
+ -- Function: int mpz_divisible_p (const mpz_t N, const mpz_t D)
+ -- Function: int mpz_divisible_ui_p (const mpz_t N, unsigned long int
+          D)
+ -- Function: int mpz_divisible_2exp_p (const mpz_t N, mp_bitcnt_t B)
+     Return non-zero if N is exactly divisible by D, or in the case of
+     'mpz_divisible_2exp_p' by 2^B.
+
+     N is divisible by D if there exists an integer Q satisfying N =
+     Q*D.  Unlike the other division functions, D=0 is accepted and
+     following the rule it can be seen that only 0 is considered
+     divisible by 0.
+
+ -- Function: int mpz_congruent_p (const mpz_t N, const mpz_t C, const
+          mpz_t D)
+ -- Function: int mpz_congruent_ui_p (const mpz_t N, unsigned long int
+          C, unsigned long int D)
+ -- Function: int mpz_congruent_2exp_p (const mpz_t N, const mpz_t C,
+          mp_bitcnt_t B)
+     Return non-zero if N is congruent to C modulo D, or in the case of
+     'mpz_congruent_2exp_p' modulo 2^B.
+
+     N is congruent to C mod D if there exists an integer Q satisfying N
+     = C + Q*D.  Unlike the other division functions, D=0 is accepted
+     and following the rule it can be seen that N and C are considered
+     congruent mod 0 only when exactly equal.

+          EXP, const mpz_t MOD)
+ -- Function: void mpz_powm_ui (mpz_t ROP, const mpz_t BASE, unsigned
+          long int EXP, const mpz_t MOD)
+     Set ROP to (BASE raised to EXP) modulo MOD.
+
+     Negative EXP is supported if the inverse BASE^(-1) mod MOD exists
+     (see 'mpz_invert' in *note Number Theoretic Functions::).  If an
+     inverse doesn't exist then a divide by zero is raised.
+
+ -- Function: void mpz_powm_sec (mpz_t ROP, const mpz_t BASE, const
+          mpz_t EXP, const mpz_t MOD)
+     Set ROP to (BASE raised to EXP) modulo MOD.
+
+     It is required that EXP > 0 and that MOD is odd.
+
+     This function is designed to take the same time and have the same
+     cache access patterns for any two same-size arguments, assuming
+     that function arguments are placed at the same position and that
+     the machine state is identical upon function entry.  This function
+     is intended for cryptographic purposes, where resilience to
+     side-channel attacks is desired.
+
+ -- Function: void mpz_pow_ui (mpz_t ROP, const mpz_t BASE, unsigned
+          long int EXP)
+ -- Function: void mpz_ui_pow_ui (mpz_t ROP, unsigned long int BASE,
+          unsigned long int EXP)
+     Set ROP to BASE raised to EXP.  The case 0^0 yields 1.

+5.8 Root Extraction Functions
+=============================
+
+ -- Function: int mpz_root (mpz_t ROP, const mpz_t OP, unsigned long int
+          N)
+     Set ROP to the truncated integer part of the Nth root of OP.
+     Return non-zero if the computation was exact, i.e., if OP is ROP to
+     the Nth power.
+
+ -- Function: void mpz_rootrem (mpz_t ROOT, mpz_t REM, const mpz_t U,
+          unsigned long int N)
+     Set ROOT to the truncated integer part of the Nth root of U.  Set
+     REM to the remainder, U-ROOT**N.
+
+ -- Function: void mpz_sqrt (mpz_t ROP, const mpz_t OP)
+     Set ROP to the truncated integer part of the square root of OP.
+
+ -- Function: void mpz_sqrtrem (mpz_t ROP1, mpz_t ROP2, const mpz_t OP)
+     Set ROP1 to the truncated integer part of the square root of OP,
+     like 'mpz_sqrt'.  Set ROP2 to the remainder OP-ROP1*ROP1, which
+     will be zero if OP is a perfect square.
+
+     If ROP1 and ROP2 are the same variable, the results are undefined.
+
+ -- Function: int mpz_perfect_power_p (const mpz_t OP)
+     Return non-zero if OP is a perfect power, i.e., if there exist
+     integers A and B, with B>1, such that OP equals A raised to the
+     power B.
+
+     Under this definition both 0 and 1 are considered to be perfect
+     powers.  Negative values of OP are accepted, but of course can only
+     be odd perfect powers.
+
+ -- Function: int mpz_perfect_square_p (const mpz_t OP)
+     Return non-zero if OP is a perfect square, i.e., if the square root
+     of OP is an integer.  Under this definition both 0 and 1 are
+     considered to be perfect squares.

+5.9 Number Theoretic Functions
+==============================
+
+ -- Function: int mpz_probab_prime_p (const mpz_t N, int REPS)
+     Determine whether N is prime.  Return 2 if N is definitely prime,
+     return 1 if N is probably prime (without being certain), or return
+     0 if N is definitely non-prime.
+
+     This function performs some trial divisions, a Baillie-PSW probable
+     prime test, then REPS-24 Miller-Rabin probabilistic primality
+     tests.  A higher REPS value will reduce the chances of a non-prime
+     being identified as "probably prime".  A composite number will be
+     identified as a prime with an asymptotic probability of less than
+     4^(-REPS).  Reasonable values of REPS are between 15 and 50.
+
+     GMP versions up to and including 6.1.2 did not use the Baillie-PSW
+     primality test.  In those older versions of GMP, this function
+     performed REPS Miller-Rabin tests.
+
+ -- Function: void mpz_nextprime (mpz_t ROP, const mpz_t OP)
+     Set ROP to the next prime greater than OP.
+
+     This function uses a probabilistic algorithm to identify primes.
+     For practical purposes it's adequate, the chance of a composite
+     passing will be extremely small.
+
+ -- Function: void mpz_gcd (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+     Set ROP to the greatest common divisor of OP1 and OP2.  The result
+     is always positive even if one or both input operands are negative.
+     Except if both inputs are zero; then this function defines gcd(0,0)
+     = 0.
+
+ -- Function: unsigned long int mpz_gcd_ui (mpz_t ROP, const mpz_t OP1,
+          unsigned long int OP2)
+     Compute the greatest common divisor of OP1 and OP2.  If ROP is not
+     'NULL', store the result there.
+
+     If the result is small enough to fit in an 'unsigned long int', it
+     is returned.  If the result does not fit, 0 is returned, and the
+     result is equal to the argument OP1.  Note that the result will
+     always fit if OP2 is non-zero.
+
+ -- Function: void mpz_gcdext (mpz_t G, mpz_t S, mpz_t T, const mpz_t A,
+          const mpz_t B)
+     Set G to the greatest common divisor of A and B, and in addition
+     set S and T to coefficients satisfying A*S + B*T = G.  The value in
+     G is always positive, even if one or both of A and B are negative
+     (or zero if both inputs are zero).  The values in S and T are
+     chosen such that normally, abs(S) < abs(B) / (2 G) and abs(T) <
+     abs(A) / (2 G), and these relations define S and T uniquely.  There
+     are a few exceptional cases:
+
+     If abs(A) = abs(B), then S = 0, T = sgn(B).
+
+     Otherwise, S = sgn(A) if B = 0 or abs(B) = 2 G, and T = sgn(B) if A
+     = 0 or abs(A) = 2 G.
+
+     In all cases, S = 0 if and only if G = abs(B), i.e., if B divides A
+     or A = B = 0.
+
+     If T or G is 'NULL' then that value is not computed.
+
+ -- Function: void mpz_lcm (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+ -- Function: void mpz_lcm_ui (mpz_t ROP, const mpz_t OP1, unsigned long
+          OP2)
+     Set ROP to the least common multiple of OP1 and OP2.  ROP is always
+     positive, irrespective of the signs of OP1 and OP2.  ROP will be
+     zero if either OP1 or OP2 is zero.
+
+ -- Function: int mpz_invert (mpz_t ROP, const mpz_t OP1, const mpz_t
+          OP2)
+     Compute the inverse of OP1 modulo OP2 and put the result in ROP.
+     If the inverse exists, the return value is non-zero and ROP will
+     satisfy 0 <= ROP < abs(OP2) (with ROP = 0 possible only when
+     abs(OP2) = 1, i.e., in the somewhat degenerate zero ring).  If an
+     inverse doesn't exist the return value is zero and ROP is
+     undefined.  The behaviour of this function is undefined when OP2 is
+     zero.
+
+ -- Function: int mpz_jacobi (const mpz_t A, const mpz_t B)
+     Calculate the Jacobi symbol (A/B).  This is defined only for B odd.
+
+ -- Function: int mpz_legendre (const mpz_t A, const mpz_t P)
+     Calculate the Legendre symbol (A/P).  This is defined only for P an
+     odd positive prime, and for such P it's identical to the Jacobi
+     symbol.
+
+ -- Function: int mpz_kronecker (const mpz_t A, const mpz_t B)
+ -- Function: int mpz_kronecker_si (const mpz_t A, long B)
+ -- Function: int mpz_kronecker_ui (const mpz_t A, unsigned long B)
+ -- Function: int mpz_si_kronecker (long A, const mpz_t B)
+ -- Function: int mpz_ui_kronecker (unsigned long A, const mpz_t B)
+     Calculate the Jacobi symbol (A/B) with the Kronecker extension
+     (a/2)=(2/a) when a odd, or (a/2)=0 when a even.
+
+     When B is odd the Jacobi symbol and Kronecker symbol are identical,
+     so 'mpz_kronecker_ui' etc can be used for mixed precision Jacobi
+     symbols too.
+
+     For more information see Henri Cohen section 1.4.2 (*note
+     References::), or any number theory textbook.  See also the example
+     program 'demos/qcn.c' which uses 'mpz_kronecker_ui'.
+
+ -- Function: mp_bitcnt_t mpz_remove (mpz_t ROP, const mpz_t OP, const
+          mpz_t F)
+     Remove all occurrences of the factor F from OP and store the result
+     in ROP.  The return value is how many such occurrences were
+     removed.
+
+ -- Function: void mpz_fac_ui (mpz_t ROP, unsigned long int N)
+ -- Function: void mpz_2fac_ui (mpz_t ROP, unsigned long int N)
+ -- Function: void mpz_mfac_uiui (mpz_t ROP, unsigned long int N,
+          unsigned long int M)
+     Set ROP to the factorial of N: 'mpz_fac_ui' computes the plain
+     factorial N!, 'mpz_2fac_ui' computes the double-factorial N!!, and
+     'mpz_mfac_uiui' the M-multi-factorial N!^(M).
+
+ -- Function: void mpz_primorial_ui (mpz_t ROP, unsigned long int N)
+     Set ROP to the primorial of N, i.e.  the product of all positive
+     prime numbers <=N.
+
+ -- Function: void mpz_bin_ui (mpz_t ROP, const mpz_t N, unsigned long
+          int K)
+ -- Function: void mpz_bin_uiui (mpz_t ROP, unsigned long int N,
+          unsigned long int K)
+     Compute the binomial coefficient N over K and store the result in
+     ROP.  Negative values of N are supported by 'mpz_bin_ui', using the
+     identity bin(-n,k) = (-1)^k * bin(n+k-1,k), see Knuth volume 1
+     section 1.2.6 part G.
+
+ -- Function: void mpz_fib_ui (mpz_t FN, unsigned long int N)
+ -- Function: void mpz_fib2_ui (mpz_t FN, mpz_t FNSUB1, unsigned long
+          int N)
+     'mpz_fib_ui' sets FN to to F[n], the N'th Fibonacci number.
+     'mpz_fib2_ui' sets FN to F[n], and FNSUB1 to F[n-1].
+
+     These functions are designed for calculating isolated Fibonacci
+     numbers.  When a sequence of values is wanted it's best to start
+     with 'mpz_fib2_ui' and iterate the defining F[n+1]=F[n]+F[n-1] or
+     similar.
+
+ -- Function: void mpz_lucnum_ui (mpz_t LN, unsigned long int N)
+ -- Function: void mpz_lucnum2_ui (mpz_t LN, mpz_t LNSUB1, unsigned long
+          int N)
+     'mpz_lucnum_ui' sets LN to to L[n], the N'th Lucas number.
+     'mpz_lucnum2_ui' sets LN to L[n], and LNSUB1 to L[n-1].
+
+     These functions are designed for calculating isolated Lucas
+     numbers.  When a sequence of values is wanted it's best to start
+     with 'mpz_lucnum2_ui' and iterate the defining L[n+1]=L[n]+L[n-1]
+     or similar.
+
+     The Fibonacci numbers and Lucas numbers are related sequences, so
+     it's never necessary to call both 'mpz_fib2_ui' and
+     'mpz_lucnum2_ui'.  The formulas for going from Fibonacci to Lucas
+     can be found in *note Lucas Numbers Algorithm::, the reverse is
+     straightforward too.

+ -- Function: int mpz_cmp (const mpz_t OP1, const mpz_t OP2)
+ -- Function: int mpz_cmp_d (const mpz_t OP1, double OP2)
+ -- Macro: int mpz_cmp_si (const mpz_t OP1, signed long int OP2)
+ -- Macro: int mpz_cmp_ui (const mpz_t OP1, unsigned long int OP2)
+     Compare OP1 and OP2.  Return a positive value if OP1 > OP2, zero if
+     OP1 = OP2, or a negative value if OP1 < OP2.
+
+     'mpz_cmp_ui' and 'mpz_cmp_si' are macros and will evaluate their
+     arguments more than once.  'mpz_cmp_d' can be called with an
+     infinity, but results are undefined for a NaN.
+
+ -- Function: int mpz_cmpabs (const mpz_t OP1, const mpz_t OP2)
+ -- Function: int mpz_cmpabs_d (const mpz_t OP1, double OP2)
+ -- Function: int mpz_cmpabs_ui (const mpz_t OP1, unsigned long int OP2)
+     Compare the absolute values of OP1 and OP2.  Return a positive
+     value if abs(OP1) > abs(OP2), zero if abs(OP1) = abs(OP2), or a
+     negative value if abs(OP1) < abs(OP2).
+
+     'mpz_cmpabs_d' can be called with an infinity, but results are
+     undefined for a NaN.
+
+ -- Macro: int mpz_sgn (const mpz_t OP)
+     Return +1 if OP > 0, 0 if OP = 0, and -1 if OP < 0.
+
+     This function is actually implemented as a macro.  It evaluates its

+
+5.11 Logical and Bit Manipulation Functions
+===========================================
+
+These functions behave as if twos complement arithmetic were used
+(although sign-magnitude is the actual implementation).  The least
+significant bit is number 0.
+
+ -- Function: void mpz_and (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+     Set ROP to OP1 bitwise-and OP2.
+
+ -- Function: void mpz_ior (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+     Set ROP to OP1 bitwise inclusive-or OP2.
+
+ -- Function: void mpz_xor (mpz_t ROP, const mpz_t OP1, const mpz_t OP2)
+     Set ROP to OP1 bitwise exclusive-or OP2.
+
+ -- Function: void mpz_com (mpz_t ROP, const mpz_t OP)
+     Set ROP to the one's complement of OP.
+
+ -- Function: mp_bitcnt_t mpz_popcount (const mpz_t OP)
+     If OP>=0, return the population count of OP, which is the number of
+     1 bits in the binary representation.  If OP<0, the number of 1s is
+     infinite, and the return value is the largest possible
+     'mp_bitcnt_t'.
+
+ -- Function: mp_bitcnt_t mpz_hamdist (const mpz_t OP1, const mpz_t OP2)
+     If OP1 and OP2 are both >=0 or both <0, return the hamming distance
+     between the two operands, which is the number of bit positions
+     where OP1 and OP2 have different bit values.  If one operand is >=0
+     and the other <0 then the number of bits different is infinite, and
+     the return value is the largest possible 'mp_bitcnt_t'.
+
+ -- Function: mp_bitcnt_t mpz_scan0 (const mpz_t OP, mp_bitcnt_t
+          STARTING_BIT)
+ -- Function: mp_bitcnt_t mpz_scan1 (const mpz_t OP, mp_bitcnt_t
+          STARTING_BIT)
+     Scan OP, starting from bit STARTING_BIT, towards more significant
+     bits, until the first 0 or 1 bit (respectively) is found.  Return
+     the index of the found bit.
+
+     If the bit at STARTING_BIT is already what's sought, then
+     STARTING_BIT is returned.
+
+     If there's no bit found, then the largest possible 'mp_bitcnt_t' is
+     returned.  This will happen in 'mpz_scan0' past the end of a
+     negative number, or 'mpz_scan1' past the end of a nonnegative
+     number.
+
+ -- Function: void mpz_setbit (mpz_t ROP, mp_bitcnt_t BIT_INDEX)
+     Set bit BIT_INDEX in ROP.

+5.12 Input and Output Functions
+===============================
+
+Functions that perform input from a stdio stream, and functions that
+output to a stdio stream, of 'mpz' numbers.  Passing a 'NULL' pointer
+for a STREAM argument to any of these functions will make them read from
+'stdin' and write to 'stdout', respectively.
+
+   When using any of these functions, it is a good idea to include
+'stdio.h' before 'gmp.h', since that will allow 'gmp.h' to define
+prototypes for these functions.
+
+   See also *note Formatted Output:: and *note Formatted Input::.
+
+ -- Function: size_t mpz_out_str (FILE *STREAM, int BASE, const mpz_t
+          OP)
+     Output OP on stdio stream STREAM, as a string of digits in base
+     BASE.  The base argument may vary from 2 to 62 or from -2 to -36.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     Return the number of bytes written, or if an error occurred, return
+     0.
+
+ -- Function: size_t mpz_inp_str (mpz_t ROP, FILE *STREAM, int BASE)
+     Input a possibly white-space preceded string in base BASE from
+     stdio stream STREAM, and put the read integer in ROP.
+
+     The BASE may vary from 2 to 62, or if BASE is 0, then the leading
+     characters are used: '0x' and '0X' for hexadecimal, '0b' and '0B'
+     for binary, '0' for octal, or decimal otherwise.
+
+     For bases up to 36, case is ignored; upper-case and lower-case
+     letters have the same value.  For bases 37 to 62, upper-case letter
+     represent the usual 10..35 while lower-case letter represent
+     36..61.
+
+     Return the number of bytes read, or if an error occurred, return 0.
+
+ -- Function: size_t mpz_out_raw (FILE *STREAM, const mpz_t OP)
+     Output OP on stdio stream STREAM, in raw binary format.  The
+     integer is written in a portable format, with 4 bytes of size
+     information, and that many bytes of limbs.  Both the size and the
+     limbs are written in decreasing significance order (i.e., in
+     big-endian).
+
+     The output can be read with 'mpz_inp_raw'.
+
+     Return the number of bytes written, or if an error occurred, return
+     0.
+
+     The output of this can not be read by 'mpz_inp_raw' from GMP 1,
+     because of changes necessary for compatibility between 32-bit and
+     64-bit machines.
+
+ -- Function: size_t mpz_inp_raw (mpz_t ROP, FILE *STREAM)
+     Input from stdio stream STREAM in the format written by
+     'mpz_out_raw', and put the result in ROP.  Return the number of
+     bytes read, or if an error occurred, return 0.
+
+     This routine can read the output from 'mpz_out_raw' also from GMP
+     1, in spite of changes necessary for compatibility between 32-bit
+     and 64-bit machines.

+5.13 Random Number Functions
+============================
+
+The random number functions of GMP come in two groups; older function
+that rely on a global state, and newer functions that accept a state
+parameter that is read and modified.  Please see the *note Random Number
+Functions:: for more information on how to use and not to use random
+number functions.
+
+ -- Function: void mpz_urandomb (mpz_t ROP, gmp_randstate_t STATE,
+          mp_bitcnt_t N)
+     Generate a uniformly distributed random integer in the range 0 to
+     2^N-1, inclusive.
+
+     The variable STATE must be initialized by calling one of the
+     'gmp_randinit' functions (*note Random State Initialization::)
+     before invoking this function.
+
+ -- Function: void mpz_urandomm (mpz_t ROP, gmp_randstate_t STATE, const
+          mpz_t N)
+     Generate a uniform random integer in the range 0 to N-1, inclusive.
+
+     The variable STATE must be initialized by calling one of the
+     'gmp_randinit' functions (*note Random State Initialization::)
+     before invoking this function.
+
+ -- Function: void mpz_rrandomb (mpz_t ROP, gmp_randstate_t STATE,
+          mp_bitcnt_t N)
+     Generate a random integer with long strings of zeros and ones in
+     the binary representation.  Useful for testing functions and
+     algorithms, since this kind of random numbers have proven to be
+     more likely to trigger corner-case bugs.  The random number will be
+     in the range 2^(N-1) to 2^N-1, inclusive.
+
+     The variable STATE must be initialized by calling one of the
+     'gmp_randinit' functions (*note Random State Initialization::)
+     before invoking this function.
+
+ -- Function: void mpz_random (mpz_t ROP, mp_size_t MAX_SIZE)
+     Generate a random integer of at most MAX_SIZE limbs.  The generated
+     random number doesn't satisfy any particular requirements of
+     randomness.  Negative random numbers are generated when MAX_SIZE is
+     negative.
+
+     This function is obsolete.  Use 'mpz_urandomb' or 'mpz_urandomm'
+     instead.
+
+ -- Function: void mpz_random2 (mpz_t ROP, mp_size_t MAX_SIZE)
+     Generate a random integer of at most MAX_SIZE limbs, with long
+     strings of zeros and ones in the binary representation.  Useful for
+     testing functions and algorithms, since this kind of random numbers
+     have proven to be more likely to trigger corner-case bugs.
+     Negative random numbers are generated when MAX_SIZE is negative.
+
+     This function is obsolete.  Use 'mpz_rrandomb' instead.

+
+ -- Function: void mpz_import (mpz_t ROP, size_t COUNT, int ORDER,

+     Set ROP from an array of word data at OP.
+
+     The parameters specify the format of the data.  COUNT many words
+     are read, each SIZE bytes.  ORDER can be 1 for most significant
+     word first or -1 for least significant first.  Within each word
+     ENDIAN can be 1 for most significant byte first, -1 for least
+     significant first, or 0 for the native endianness of the host CPU.
+     The most significant NAILS bits of each word are skipped, this can
+     be 0 to use the full words.
+
+     There is no sign taken from the data, ROP will simply be a positive
+     integer.  An application can handle any sign itself, and apply it
+     for instance with 'mpz_neg'.
+
+     There are no data alignment restrictions on OP, any address is
+     allowed.
+
+     Here's an example converting an array of 'unsigned long' data, most
+     significant element first, and host byte order within each value.
+
+          unsigned long  a[20];
+          /* Initialize Z and A */
+          mpz_import (z, 20, 1, sizeof(a[0]), 0, 0, a);
+
+     This example assumes the full 'sizeof' bytes are used for data in
+     the given type, which is usually true, and certainly true for
+     'unsigned long' everywhere we know of.  However on Cray vector
+     systems it may be noted that 'short' and 'int' are always stored in
+     8 bytes (and with 'sizeof' indicating that) but use only 32 or 46
+     bits.  The NAILS feature can account for this, by passing for
+     instance '8*sizeof(int)-INT_BIT'.
+
+ -- Function: void * mpz_export (void *ROP, size_t *COUNTP, int ORDER,
+          size_t SIZE, int ENDIAN, size_t NAILS, const mpz_t OP)
+     Fill ROP with word data from OP.
+
+     The parameters specify the format of the data produced.  Each word
+     will be SIZE bytes and ORDER can be 1 for most significant word
+     first or -1 for least significant first.  Within each word ENDIAN
+     can be 1 for most significant byte first, -1 for least significant
+     first, or 0 for the native endianness of the host CPU.  The most
+     significant NAILS bits of each word are unused and set to zero,
+     this can be 0 to produce full words.
+
+     The number of words produced is written to '*COUNTP', or COUNTP can
+     be 'NULL' to discard the count.  ROP must have enough space for the
+     data, or if ROP is 'NULL' then a result array of the necessary size
+     is allocated using the current GMP allocation function (*note
+     Custom Allocation::).  In either case the return value is the
+     destination used, either ROP or the allocated block.
+
+     If OP is non-zero then the most significant word produced will be
+     non-zero.  If OP is zero then the count returned will be zero and
+     nothing written to ROP.  If ROP is 'NULL' in this case, no block is
+     allocated, just 'NULL' is returned.
+
+     The sign of OP is ignored, just the absolute value is exported.  An
+     application can use 'mpz_sgn' to get the sign and handle it as
+     desired.  (*note Integer Comparisons::)
+
+     There are no data alignment restrictions on ROP, any address is
+     allowed.
+
+     When an application is allocating space itself the required size
+     can be determined with a calculation like the following.  Since
+     'mpz_sizeinbase' always returns at least 1, 'count' here will be at
+     least one, which avoids any portability problems with 'malloc(0)',
+     though if 'z' is zero no space at all is actually needed (or
+     written).
+
+          numb = 8*size - nail;
+          count = (mpz_sizeinbase (z, 2) + numb-1) / numb;
+          p = malloc (count * size);

+5.15 Miscellaneous Functions
+============================
+
+ -- Function: int mpz_fits_ulong_p (const mpz_t OP)
+ -- Function: int mpz_fits_slong_p (const mpz_t OP)
+ -- Function: int mpz_fits_uint_p (const mpz_t OP)
+ -- Function: int mpz_fits_sint_p (const mpz_t OP)
+ -- Function: int mpz_fits_ushort_p (const mpz_t OP)
+ -- Function: int mpz_fits_sshort_p (const mpz_t OP)
+     Return non-zero iff the value of OP fits in an 'unsigned long int',
+     'signed long int', 'unsigned int', 'signed int', 'unsigned short
+     int', or 'signed short int', respectively.  Otherwise, return zero.
+
+ -- Macro: int mpz_odd_p (const mpz_t OP)
+ -- Macro: int mpz_even_p (const mpz_t OP)
+     Determine whether OP is odd or even, respectively.  Return non-zero
+     if yes, zero if no.  These macros evaluate their argument more than
+     once.
+
+ -- Function: size_t mpz_sizeinbase (const mpz_t OP, int BASE)
+     Return the size of OP measured in number of digits in the given
+     BASE.  BASE can vary from 2 to 62.  The sign of OP is ignored, just
+     the absolute value is used.  The result will be either exact or 1
+     too big.  If BASE is a power of 2, the result is always exact.  If
+     OP is zero the return value is always 1.
+
+     This function can be used to determine the space required when
+     converting OP to a string.  The right amount of allocation is
+     normally two more than the value returned by 'mpz_sizeinbase', one
+     extra for a minus sign and one for the null-terminator.
+
+     It will be noted that 'mpz_sizeinbase(OP,2)' can be used to locate
+     the most significant 1 bit in OP, counting from 1.  (Unlike the
+     bitwise functions which start from 0, *Note Logical and Bit
+     Manipulation Functions: Integer Logic and Bit Fiddling.)

+
+5.16 Special Functions
+======================
+
+The functions in this section are for various special purposes.  Most
+applications will not need them.
+
+ -- Function: void mpz_array_init (mpz_t INTEGER_ARRAY, mp_size_t
+          ARRAY_SIZE, mp_size_t FIXED_NUM_BITS)
+     *This is an obsolete function.  Do not use it.*
+
+ -- Function: void * _mpz_realloc (mpz_t INTEGER, mp_size_t NEW_ALLOC)
+     Change the space for INTEGER to NEW_ALLOC limbs.  The value in
+     INTEGER is preserved if it fits, or is set to 0 if not.  The return
+     value is not useful to applications and should be ignored.
+
+     'mpz_realloc2' is the preferred way to accomplish allocation
+     changes like this.  'mpz_realloc2' and '_mpz_realloc' are the same
+     except that '_mpz_realloc' takes its size in limbs.
+
+ -- Function: mp_limb_t mpz_getlimbn (const mpz_t OP, mp_size_t N)
+     Return limb number N from OP.  The sign of OP is ignored, just the
+     absolute value is used.  The least significant limb is number 0.
+
+     'mpz_size' can be used to find how many limbs make up OP.
+     'mpz_getlimbn' returns zero if N is outside the range 0 to
+     'mpz_size(OP)-1'.
+
+ -- Function: size_t mpz_size (const mpz_t OP)
+     Return the size of OP measured in number of limbs.  If OP is zero,
+     the returned value will be zero.
+
+ -- Function: const mp_limb_t * mpz_limbs_read (const mpz_t X)
+     Return a pointer to the limb array representing the absolute value
+     of X.  The size of the array is 'mpz_size(X)'.  Intended for read
+     access only.
+
+ -- Function: mp_limb_t * mpz_limbs_write (mpz_t X, mp_size_t N)
+ -- Function: mp_limb_t * mpz_limbs_modify (mpz_t X, mp_size_t N)
+     Return a pointer to the limb array, intended for write access.  The
+     array is reallocated as needed, to make room for N limbs.  Requires
+     N > 0.  The 'mpz_limbs_modify' function returns an array that holds
+     the old absolute value of X, while 'mpz_limbs_write' may destroy
+     the old value and return an array with unspecified contents.
+
+ -- Function: void mpz_limbs_finish (mpz_t X, mp_size_t S)
+     Updates the internal size field of X.  Used after writing to the
+     limb array pointer returned by 'mpz_limbs_write' or
+     'mpz_limbs_modify' is completed.  The array should contain abs(S)
+     valid limbs, representing the new absolute value for X, and the
+     sign of X is taken from the sign of S.  This function never
+     reallocates X, so the limb pointer remains valid.
+
+     void foo (mpz_t x)
+     {
+       mp_size_t n, i;
+       mp_limb_t *xp;
+
+       n = mpz_size (x);
+       xp = mpz_limbs_modify (x, 2*n);
+       for (i = 0; i < n; i++)
+         xp[n+i] = xp[n-1-i];
+       mpz_limbs_finish (x, mpz_sgn (x) < 0 ? - 2*n : 2*n);
+     }
+
+ -- Function: mpz_srcptr mpz_roinit_n (mpz_t X, const mp_limb_t *XP,
+          mp_size_t XS)
+     Special initialization of X, using the given limb array and size.
+     X should be treated as read-only: it can be passed safely as input
+     to any mpz function, but not as an output.  The array XP must point
+     to at least a readable limb, its size is abs(XS), and the sign of X
+     is the sign of XS.  For convenience, the function returns X, but
+     cast to a const pointer type.
+
+     void foo (mpz_t x)
+     {
+       static const mp_limb_t y[3] = { 0x1, 0x2, 0x3 };
+       mpz_t tmp;
+       mpz_add (x, x, mpz_roinit_n (tmp, y, 3));
+     }
+
+ -- Macro: mpz_t MPZ_ROINIT_N (mp_limb_t *XP, mp_size_t XS)
+     This macro expands to an initializer which can be assigned to an
+     mpz_t variable.  The limb array XP must point to at least a
+     readable limb, moreover, unlike the 'mpz_roinit_n' function, the
+     array must be normalized: if XS is non-zero, then 'XP[abs(XS)-1]'
+     must be non-zero.  Intended primarily for constant values.  Using
+     it for non-constant values requires a C compiler supporting C99.
+
+     void foo (mpz_t x)
+     {
+       static const mp_limb_t ya[3] = { 0x1, 0x2, 0x3 };
+       static const mpz_t y = MPZ_ROINIT_N ((mp_limb_t *) ya, 3);
+
+       mpz_add (x, x, y);

+6 Rational Number Functions
+***************************
+
+This chapter describes the GMP functions for performing arithmetic on
+rational numbers.  These functions start with the prefix 'mpq_'.
+
+   Rational numbers are stored in objects of type 'mpq_t'.
+
+   All rational arithmetic functions assume operands have a canonical
+form, and canonicalize their result.  The canonical form means that the
+denominator and the numerator have no common factors, and that the
+denominator is positive.  Zero has the unique representation 0/1.
+
+   Pure assignment functions do not canonicalize the assigned variable.
+It is the responsibility of the user to canonicalize the assigned
+variable before any arithmetic operations are performed on that
+variable.
+
+ -- Function: void mpq_canonicalize (mpq_t OP)
+     Remove any factors that are common to the numerator and denominator
+     of OP, and make the denominator positive.

+
+6.1 Initialization and Assignment Functions
+===========================================
+
+ -- Function: void mpq_init (mpq_t X)
+     Initialize X and set it to 0/1.  Each variable should normally only
+     be initialized once, or at least cleared out (using the function
+     'mpq_clear') between each initialization.
+
+ -- Function: void mpq_inits (mpq_t X, ...)
+     Initialize a NULL-terminated list of 'mpq_t' variables, and set
+     their values to 0/1.
+
+ -- Function: void mpq_clear (mpq_t X)
+     Free the space occupied by X.  Make sure to call this function for
+     all 'mpq_t' variables when you are done with them.
+
+ -- Function: void mpq_clears (mpq_t X, ...)
+     Free the space occupied by a NULL-terminated list of 'mpq_t'
+     variables.
+
+ -- Function: void mpq_set (mpq_t ROP, const mpq_t OP)
+ -- Function: void mpq_set_z (mpq_t ROP, const mpz_t OP)
+     Assign ROP from OP.
+
+ -- Function: void mpq_set_ui (mpq_t ROP, unsigned long int OP1,
+          unsigned long int OP2)
+ -- Function: void mpq_set_si (mpq_t ROP, signed long int OP1, unsigned
+          long int OP2)
+     Set the value of ROP to OP1/OP2.  Note that if OP1 and OP2 have
+     common factors, ROP has to be passed to 'mpq_canonicalize' before
+     any operations are performed on ROP.
+
+ -- Function: int mpq_set_str (mpq_t ROP, const char *STR, int BASE)
+     Set ROP from a null-terminated string STR in the given BASE.
+
+     The string can be an integer like "41" or a fraction like "41/152".
+     The fraction must be in canonical form (*note Rational Number
+     Functions::), or if not then 'mpq_canonicalize' must be called.
+
+     The numerator and optional denominator are parsed the same as in
+     'mpz_set_str' (*note Assigning Integers::).  White space is allowed
+     in the string, and is simply ignored.  The BASE can vary from 2 to
+     62, or if BASE is 0 then the leading characters are used: '0x' or
+     '0X' for hex, '0b' or '0B' for binary, '0' for octal, or decimal
+     otherwise.  Note that this is done separately for the numerator and
+     denominator, so for instance '0xEF/100' is 239/100, whereas
+     '0xEF/0x100' is 239/256.
+
+     The return value is 0 if the entire string is a valid number, or -1
+     if not.
+
+ -- Function: void mpq_swap (mpq_t ROP1, mpq_t ROP2)
+     Swap the values ROP1 and ROP2 efficiently.
+
+
+File: gmp.info,  Node: Rational Conversions,  Next: Rational Arithmetic,  Prev: Initializing Rationals,  Up: Rational Number Functions
+
+6.2 Conversion Functions
+========================
+
+ -- Function: double mpq_get_d (const mpq_t OP)
+     Convert OP to a 'double', truncating if necessary (i.e. rounding
+     towards zero).
+
+     If the exponent from the conversion is too big or too small to fit
+     a 'double' then the result is system dependent.  For too big an
+     infinity is returned when available.  For too small 0.0 is normally
+     returned.  Hardware overflow, underflow and denorm traps may or may
+     not occur.
+
+ -- Function: void mpq_set_d (mpq_t ROP, double OP)
+ -- Function: void mpq_set_f (mpq_t ROP, const mpf_t OP)
+     Set ROP to the value of OP.  There is no rounding, this conversion
+     is exact.
+
+ -- Function: char * mpq_get_str (char *STR, int BASE, const mpq_t OP)
+     Convert OP to a string of digits in base BASE.  The base argument
+     may vary from 2 to 62 or from -2 to -36.  The string will be of the
+     form 'num/den', or if the denominator is 1 then just 'num'.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     If STR is 'NULL', the result string is allocated using the current
+     allocation function (*note Custom Allocation::).  The block will be
+     'strlen(str)+1' bytes, that being exactly enough for the string and
+     null-terminator.
+
+     If STR is not 'NULL', it should point to a block of storage large
+     enough for the result, that being
+
+          mpz_sizeinbase (mpq_numref(OP), BASE)
+          + mpz_sizeinbase (mpq_denref(OP), BASE) + 3
+
+     The three extra bytes are for a possible minus sign, possible
+     slash, and the null-terminator.
+
+     A pointer to the result string is returned, being either the
+     allocated block, or the given STR.

+6.3 Arithmetic Functions
+========================
+
+ -- Function: void mpq_add (mpq_t SUM, const mpq_t ADDEND1, const mpq_t
+          ADDEND2)
+     Set SUM to ADDEND1 + ADDEND2.
+
+ -- Function: void mpq_sub (mpq_t DIFFERENCE, const mpq_t MINUEND, const
+          mpq_t SUBTRAHEND)
+     Set DIFFERENCE to MINUEND - SUBTRAHEND.
+
+ -- Function: void mpq_mul (mpq_t PRODUCT, const mpq_t MULTIPLIER, const
+          mpq_t MULTIPLICAND)
+     Set PRODUCT to MULTIPLIER times MULTIPLICAND.
+
+ -- Function: void mpq_mul_2exp (mpq_t ROP, const mpq_t OP1, mp_bitcnt_t
+          OP2)
+     Set ROP to OP1 times 2 raised to OP2.
+
+ -- Function: void mpq_div (mpq_t QUOTIENT, const mpq_t DIVIDEND, const
+          mpq_t DIVISOR)
+     Set QUOTIENT to DIVIDEND/DIVISOR.
+
+ -- Function: void mpq_div_2exp (mpq_t ROP, const mpq_t OP1, mp_bitcnt_t
+          OP2)
+     Set ROP to OP1 divided by 2 raised to OP2.
+
+ -- Function: void mpq_neg (mpq_t NEGATED_OPERAND, const mpq_t OPERAND)
+     Set NEGATED_OPERAND to -OPERAND.
+
+ -- Function: void mpq_abs (mpq_t ROP, const mpq_t OP)
+     Set ROP to the absolute value of OP.
+
+ -- Function: void mpq_inv (mpq_t INVERTED_NUMBER, const mpq_t NUMBER)
+     Set INVERTED_NUMBER to 1/NUMBER.  If the new denominator is zero,
+     this routine will divide by zero.

+
+6.4 Comparison Functions
+========================
+
+ -- Function: int mpq_cmp (const mpq_t OP1, const mpq_t OP2)
+ -- Function: int mpq_cmp_z (const mpq_t OP1, const mpz_t OP2)
+     Compare OP1 and OP2.  Return a positive value if OP1 > OP2, zero if
+     OP1 = OP2, and a negative value if OP1 < OP2.
+
+     To determine if two rationals are equal, 'mpq_equal' is faster than
+     'mpq_cmp'.
+
+ -- Macro: int mpq_cmp_ui (const mpq_t OP1, unsigned long int NUM2,
+          unsigned long int DEN2)
+ -- Macro: int mpq_cmp_si (const mpq_t OP1, long int NUM2, unsigned long
+          int DEN2)
+     Compare OP1 and NUM2/DEN2.  Return a positive value if OP1 >
+     NUM2/DEN2, zero if OP1 = NUM2/DEN2, and a negative value if OP1 <
+     NUM2/DEN2.
+
+     NUM2 and DEN2 are allowed to have common factors.
+
+     These functions are implemented as a macros and evaluate their
+     arguments multiple times.
+
+ -- Macro: int mpq_sgn (const mpq_t OP)
+     Return +1 if OP > 0, 0 if OP = 0, and -1 if OP < 0.
+
+     This function is actually implemented as a macro.  It evaluates its
+     argument multiple times.
+
+ -- Function: int mpq_equal (const mpq_t OP1, const mpq_t OP2)
+     Return non-zero if OP1 and OP2 are equal, zero if they are
+     non-equal.  Although 'mpq_cmp' can be used for the same purpose,
+     this function is much faster.

+
+6.5 Applying Integer Functions to Rationals
+===========================================
+
+The set of 'mpq' functions is quite small.  In particular, there are few
+functions for either input or output.  The following functions give
+direct access to the numerator and denominator of an 'mpq_t'.
+
+   Note that if an assignment to the numerator and/or denominator could
+take an 'mpq_t' out of the canonical form described at the start of this
+chapter (*note Rational Number Functions::) then 'mpq_canonicalize' must
+be called before any other 'mpq' functions are applied to that 'mpq_t'.
+
+ -- Macro: mpz_t mpq_numref (const mpq_t OP)
+ -- Macro: mpz_t mpq_denref (const mpq_t OP)
+     Return a reference to the numerator and denominator of OP,
+     respectively.  The 'mpz' functions can be used on the result of
+     these macros.
+
+ -- Function: void mpq_get_num (mpz_t NUMERATOR, const mpq_t RATIONAL)
+ -- Function: void mpq_get_den (mpz_t DENOMINATOR, const mpq_t RATIONAL)
+ -- Function: void mpq_set_num (mpq_t RATIONAL, const mpz_t NUMERATOR)
+ -- Function: void mpq_set_den (mpq_t RATIONAL, const mpz_t DENOMINATOR)
+     Get or set the numerator or denominator of a rational.  These
+     functions are equivalent to calling 'mpz_set' with an appropriate
+     'mpq_numref' or 'mpq_denref'.  Direct use of 'mpq_numref' or
+     'mpq_denref' is recommended instead of these functions.
+
+
+File: gmp.info,  Node: I/O of Rationals,  Prev: Applying Integer Functions,  Up: Rational Number Functions
+
+6.6 Input and Output Functions
+==============================
+
+Functions that perform input from a stdio stream, and functions that
+output to a stdio stream, of 'mpq' numbers.  Passing a 'NULL' pointer
+for a STREAM argument to any of these functions will make them read from
+'stdin' and write to 'stdout', respectively.
+
+   When using any of these functions, it is a good idea to include
+'stdio.h' before 'gmp.h', since that will allow 'gmp.h' to define
+prototypes for these functions.
+
+   See also *note Formatted Output:: and *note Formatted Input::.
+
+ -- Function: size_t mpq_out_str (FILE *STREAM, int BASE, const mpq_t
+          OP)
+     Output OP on stdio stream STREAM, as a string of digits in base
+     BASE.  The base argument may vary from 2 to 62 or from -2 to -36.
+     Output is in the form 'num/den' or if the denominator is 1 then
+     just 'num'.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     Return the number of bytes written, or if an error occurred, return
+     0.
+
+ -- Function: size_t mpq_inp_str (mpq_t ROP, FILE *STREAM, int BASE)
+     Read a string of digits from STREAM and convert them to a rational
+     in ROP.  Any initial white-space characters are read and discarded.
+     Return the number of characters read (including white space), or 0
+     if a rational could not be read.
+
+     The input can be a fraction like '17/63' or just an integer like
+     '123'.  Reading stops at the first character not in this form, and
+     white space is not permitted within the string.  If the input might
+     not be in canonical form, then 'mpq_canonicalize' must be called
+     (*note Rational Number Functions::).
+
+     The BASE can be between 2 and 62, or can be 0 in which case the
+     leading characters of the string determine the base, '0x' or '0X'
+     for hexadecimal, '0b' and '0B' for binary, '0' for octal, or
+     decimal otherwise.  The leading characters are examined separately
+     for the numerator and denominator of a fraction, so for instance
+     '0x10/11' is 16/11, whereas '0x10/0x11' is 16/17.

+7 Floating-point Functions
+**************************
+
+GMP floating point numbers are stored in objects of type 'mpf_t' and
+functions operating on them have an 'mpf_' prefix.
+
+   The mantissa of each float has a user-selectable precision, in
+practice only limited by available memory.  Each variable has its own
+precision, and that can be increased or decreased at any time.  This
+selectable precision is a minimum value, GMP rounds it up to a whole
+limb.
+
+   The accuracy of a calculation is determined by the priorly set
+precision of the destination variable and the numeric values of the
+input variables.  Input variables' set precisions do not affect
+calculations (except indirectly as their values might have been affected
+when they were assigned).
+
+   The exponent of each float has fixed precision, one machine word on
+most systems.  In the current implementation the exponent is a count of
+limbs, so for example on a 32-bit system this means a range of roughly
+2^-68719476768 to 2^68719476736, or on a 64-bit system this will be much
+greater.  Note however that 'mpf_get_str' can only return an exponent
+which fits an 'mp_exp_t' and currently 'mpf_set_str' doesn't accept
+exponents bigger than a 'long'.
+
+   Each variable keeps track of the mantissa data actually in use.  This
+means that if a float is exactly represented in only a few bits then
+only those bits will be used in a calculation, even if the variable's
+selected precision is high.  This is a performance optimization; it does
+not affect the numeric results.
+
+   Internally, GMP sometimes calculates with higher precision than that
+of the destination variable in order to limit errors.  Final results are
+always truncated to the destination variable's precision.
+
+   The mantissa is stored in binary.  One consequence of this is that
+decimal fractions like 0.1 cannot be represented exactly.  The same is
+true of plain IEEE 'double' floats.  This makes both highly unsuitable
+for calculations involving money or other values that should be exact
+decimal fractions.  (Suitably scaled integers, or perhaps rationals, are
+better choices.)
+
+   The 'mpf' functions and variables have no special notion of infinity
+or not-a-number, and applications must take care not to overflow the
+exponent or results will be unpredictable.
+
+   Note that the 'mpf' functions are _not_ intended as a smooth
+extension to IEEE P754 arithmetic.  In particular results obtained on
+one computer often differ from the results on a computer with a
+different word size.
+
+   New projects should consider using the GMP extension library MPFR
+(<http://mpfr.org>) instead.  MPFR provides well-defined precision and
+accurate rounding, and thereby naturally extends IEEE P754.

+7.1 Initialization Functions
+============================
+
+ -- Function: void mpf_set_default_prec (mp_bitcnt_t PREC)
+     Set the default precision to be *at least* PREC bits.  All
+     subsequent calls to 'mpf_init' will use this precision, but
+     previously initialized variables are unaffected.
+
+ -- Function: mp_bitcnt_t mpf_get_default_prec (void)
+     Return the default precision actually used.
+
+   An 'mpf_t' object must be initialized before storing the first value
+in it.  The functions 'mpf_init' and 'mpf_init2' are used for that
+purpose.
+
+ -- Function: void mpf_init (mpf_t X)
+     Initialize X to 0.  Normally, a variable should be initialized once
+     only or at least be cleared, using 'mpf_clear', between
+     initializations.  The precision of X is undefined unless a default
+     precision has already been established by a call to
+     'mpf_set_default_prec'.
+
+ -- Function: void mpf_init2 (mpf_t X, mp_bitcnt_t PREC)
+     Initialize X to 0 and set its precision to be *at least* PREC bits.
+     Normally, a variable should be initialized once only or at least be
+     cleared, using 'mpf_clear', between initializations.
+
+ -- Function: void mpf_inits (mpf_t X, ...)
+     Initialize a NULL-terminated list of 'mpf_t' variables, and set
+     their values to 0.  The precision of the initialized variables is
+     undefined unless a default precision has already been established
+     by a call to 'mpf_set_default_prec'.
+
+ -- Function: void mpf_clear (mpf_t X)
+     Free the space occupied by X.  Make sure to call this function for
+     all 'mpf_t' variables when you are done with them.
+
+ -- Function: void mpf_clears (mpf_t X, ...)
+     Free the space occupied by a NULL-terminated list of 'mpf_t'
+     variables.
+
+   Here is an example on how to initialize floating-point variables:
+     {
+       mpf_t x, y;
+       mpf_init (x);           /* use default precision */
+       mpf_init2 (y, 256);     /* precision _at least_ 256 bits */
+       ...
+       /* Unless the program is about to exit, do ... */
+       mpf_clear (x);
+       mpf_clear (y);
+     }
+
+   The following three functions are useful for changing the precision
+during a calculation.  A typical use would be for adjusting the
+precision gradually in iterative algorithms like Newton-Raphson, making
+the computation precision closely match the actual accurate part of the
+numbers.
+
+ -- Function: mp_bitcnt_t mpf_get_prec (const mpf_t OP)
+     Return the current precision of OP, in bits.
+
+ -- Function: void mpf_set_prec (mpf_t ROP, mp_bitcnt_t PREC)
+     Set the precision of ROP to be *at least* PREC bits.  The value in
+     ROP will be truncated to the new precision.
+
+     This function requires a call to 'realloc', and so should not be
+     used in a tight loop.
+
+ -- Function: void mpf_set_prec_raw (mpf_t ROP, mp_bitcnt_t PREC)
+     Set the precision of ROP to be *at least* PREC bits, without
+     changing the memory allocated.
+
+     PREC must be no more than the allocated precision for ROP, that
+     being the precision when ROP was initialized, or in the most recent
+     'mpf_set_prec'.
+
+     The value in ROP is unchanged, and in particular if it had a higher
+     precision than PREC it will retain that higher precision.  New
+     values written to ROP will use the new PREC.
+
+     Before calling 'mpf_clear' or the full 'mpf_set_prec', another
+     'mpf_set_prec_raw' call must be made to restore ROP to its original
+     allocated precision.  Failing to do so will have unpredictable
+     results.
+
+     'mpf_get_prec' can be used before 'mpf_set_prec_raw' to get the
+     original allocated precision.  After 'mpf_set_prec_raw' it reflects
+     the PREC value set.
+
+     'mpf_set_prec_raw' is an efficient way to use an 'mpf_t' variable
+     at different precisions during a calculation, perhaps to gradually
+     increase precision in an iteration, or just to use various
+     different precisions for different purposes during a calculation.

+
+7.2 Assignment Functions
+========================
+
+These functions assign new values to already initialized floats (*note
+Initializing Floats::).
+
+ -- Function: void mpf_set (mpf_t ROP, const mpf_t OP)
+ -- Function: void mpf_set_ui (mpf_t ROP, unsigned long int OP)
+ -- Function: void mpf_set_si (mpf_t ROP, signed long int OP)
+ -- Function: void mpf_set_d (mpf_t ROP, double OP)
+ -- Function: void mpf_set_z (mpf_t ROP, const mpz_t OP)
+ -- Function: void mpf_set_q (mpf_t ROP, const mpq_t OP)
+     Set the value of ROP from OP.
+
+ -- Function: int mpf_set_str (mpf_t ROP, const char *STR, int BASE)
+     Set the value of ROP from the string in STR.  The string is of the
+     form 'M@N' or, if the base is 10 or less, alternatively 'MeN'.  'M'
+     is the mantissa and 'N' is the exponent.  The mantissa is always in
+     the specified base.  The exponent is either in the specified base
+     or, if BASE is negative, in decimal.  The decimal point expected is
+     taken from the current locale, on systems providing 'localeconv'.
+
+     The argument BASE may be in the ranges 2 to 62, or -62 to -2.
+     Negative values are used to specify that the exponent is in
+     decimal.
+
+     For bases up to 36, case is ignored; upper-case and lower-case
+     letters have the same value; for bases 37 to 62, upper-case letter
+     represent the usual 10..35 while lower-case letter represent
+     36..61.
+
+     Unlike the corresponding 'mpz' function, the base will not be
+     determined from the leading characters of the string if BASE is 0.
+     This is so that numbers like '0.23' are not interpreted as octal.
+
+     White space is allowed in the string, and is simply ignored.  [This
+     is not really true; white-space is ignored in the beginning of the
+     string and within the mantissa, but not in other places, such as
+     after a minus sign or in the exponent.  We are considering changing
+     the definition of this function, making it fail when there is any
+     white-space in the input, since that makes a lot of sense.  Please
+     tell us your opinion about this change.  Do you really want it to
+     accept "3 14" as meaning 314 as it does now?]
+
+     This function returns 0 if the entire string is a valid number in
+     base BASE.  Otherwise it returns -1.
+
+ -- Function: void mpf_swap (mpf_t ROP1, mpf_t ROP2)
+     Swap ROP1 and ROP2 efficiently.  Both the values and the precisions
+     of the two variables are swapped.

+
+7.3 Combined Initialization and Assignment Functions
+====================================================
+
+For convenience, GMP provides a parallel series of initialize-and-set
+functions which initialize the output and then store the value there.
+These functions' names have the form 'mpf_init_set...'
+
+   Once the float has been initialized by any of the 'mpf_init_set...'
+functions, it can be used as the source or destination operand for the
+ordinary float functions.  Don't use an initialize-and-set function on a
+variable already initialized!
+
+ -- Function: void mpf_init_set (mpf_t ROP, const mpf_t OP)
+ -- Function: void mpf_init_set_ui (mpf_t ROP, unsigned long int OP)
+ -- Function: void mpf_init_set_si (mpf_t ROP, signed long int OP)
+ -- Function: void mpf_init_set_d (mpf_t ROP, double OP)
+     Initialize ROP and set its value from OP.
+
+     The precision of ROP will be taken from the active default
+     precision, as set by 'mpf_set_default_prec'.
+
+ -- Function: int mpf_init_set_str (mpf_t ROP, const char *STR, int
+          BASE)
+     Initialize ROP and set its value from the string in STR.  See
+     'mpf_set_str' above for details on the assignment operation.
+
+     Note that ROP is initialized even if an error occurs.  (I.e., you
+     have to call 'mpf_clear' for it.)
+
+     The precision of ROP will be taken from the active default
+     precision, as set by 'mpf_set_default_prec'.

+
+7.4 Conversion Functions
+========================
+
+ -- Function: double mpf_get_d (const mpf_t OP)
+     Convert OP to a 'double', truncating if necessary (i.e. rounding
+     towards zero).
+
+     If the exponent in OP is too big or too small to fit a 'double'
+     then the result is system dependent.  For too big an infinity is
+     returned when available.  For too small 0.0 is normally returned.
+     Hardware overflow, underflow and denorm traps may or may not occur.
+
+ -- Function: double mpf_get_d_2exp (signed long int *EXP, const mpf_t
+          OP)
+     Convert OP to a 'double', truncating if necessary (i.e. rounding
+     towards zero), and with an exponent returned separately.
+
+     The return value is in the range 0.5<=abs(D)<1 and the exponent is
+     stored to '*EXP'.  D * 2^EXP is the (truncated) OP value.  If OP is
+     zero, the return is 0.0 and 0 is stored to '*EXP'.
+
+     This is similar to the standard C 'frexp' function (*note
+     (libc)Normalization Functions::).
+
+ -- Function: long mpf_get_si (const mpf_t OP)
+ -- Function: unsigned long mpf_get_ui (const mpf_t OP)
+     Convert OP to a 'long' or 'unsigned long', truncating any fraction
+     part.  If OP is too big for the return type, the result is
+     undefined.
+
+     See also 'mpf_fits_slong_p' and 'mpf_fits_ulong_p' (*note
+     Miscellaneous Float Functions::).
+
+ -- Function: char * mpf_get_str (char *STR, mp_exp_t *EXPPTR, int BASE,
+          size_t N_DIGITS, const mpf_t OP)
+     Convert OP to a string of digits in base BASE.  The base argument
+     may vary from 2 to 62 or from -2 to -36.  Up to N_DIGITS digits
+     will be generated.  Trailing zeros are not returned.  No more
+     digits than can be accurately represented by OP are ever generated.
+     If N_DIGITS is 0 then that accurate maximum number of digits are
+     generated.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     If STR is 'NULL', the result string is allocated using the current
+     allocation function (*note Custom Allocation::).  The block will be
+     'strlen(str)+1' bytes, that being exactly enough for the string and
+     null-terminator.
+
+     If STR is not 'NULL', it should point to a block of N_DIGITS + 2
+     bytes, that being enough for the mantissa, a possible minus sign,
+     and a null-terminator.  When N_DIGITS is 0 to get all significant
+     digits, an application won't be able to know the space required,
+     and STR should be 'NULL' in that case.
+
+     The generated string is a fraction, with an implicit radix point
+     immediately to the left of the first digit.  The applicable
+     exponent is written through the EXPPTR pointer.  For example, the
+     number 3.1416 would be returned as string "31416" and exponent 1.
+
+     When OP is zero, an empty string is produced and the exponent
+     returned is 0.
+
+     A pointer to the result string is returned, being either the
+     allocated block or the given STR.

+7.5 Arithmetic Functions
+========================
+
+ -- Function: void mpf_add (mpf_t ROP, const mpf_t OP1, const mpf_t OP2)
+ -- Function: void mpf_add_ui (mpf_t ROP, const mpf_t OP1, unsigned long

+ -- Function: void mpf_mul (mpf_t ROP, const mpf_t OP1, const mpf_t OP2)
+ -- Function: void mpf_mul_ui (mpf_t ROP, const mpf_t OP1, unsigned long
+          int OP2)
+     Set ROP to OP1 times OP2.
+
+   Division is undefined if the divisor is zero, and passing a zero
+divisor to the divide functions will make these functions intentionally
+divide by zero.  This lets the user handle arithmetic exceptions in
+these functions in the same manner as other arithmetic exceptions.
+
+ -- Function: void mpf_div (mpf_t ROP, const mpf_t OP1, const mpf_t OP2)
+ -- Function: void mpf_ui_div (mpf_t ROP, unsigned long int OP1, const

+
+ -- Function: void mpf_abs (mpf_t ROP, const mpf_t OP)
+     Set ROP to the absolute value of OP.
+
+ -- Function: void mpf_mul_2exp (mpf_t ROP, const mpf_t OP1, mp_bitcnt_t
+          OP2)
+     Set ROP to OP1 times 2 raised to OP2.
+
+ -- Function: void mpf_div_2exp (mpf_t ROP, const mpf_t OP1, mp_bitcnt_t
+          OP2)
+     Set ROP to OP1 divided by 2 raised to OP2.

+
+ -- Function: int mpf_cmp (const mpf_t OP1, const mpf_t OP2)
+ -- Function: int mpf_cmp_z (const mpf_t OP1, const mpz_t OP2)
+ -- Function: int mpf_cmp_d (const mpf_t OP1, double OP2)
+ -- Function: int mpf_cmp_ui (const mpf_t OP1, unsigned long int OP2)
+ -- Function: int mpf_cmp_si (const mpf_t OP1, signed long int OP2)
+     Compare OP1 and OP2.  Return a positive value if OP1 > OP2, zero if
+     OP1 = OP2, and a negative value if OP1 < OP2.
+
+     'mpf_cmp_d' can be called with an infinity, but results are
+     undefined for a NaN.
+
+ -- Function: int mpf_eq (const mpf_t OP1, const mpf_t OP2, mp_bitcnt_t
+          op3)
+     *This function is mathematically ill-defined and should not be
+     used.*
+
+     Return non-zero if the first OP3 bits of OP1 and OP2 are equal,
+     zero otherwise.  Note that numbers like e.g., 256 (binary
+     100000000) and 255 (binary 11111111) will never be equal by this
+     function's measure, and furthermore that 0 will only be equal to
+     itself.
+
+ -- Function: void mpf_reldiff (mpf_t ROP, const mpf_t OP1, const mpf_t
+          OP2)
+     Compute the relative difference between OP1 and OP2 and store the
+     result in ROP.  This is abs(OP1-OP2)/OP1.
+
+ -- Macro: int mpf_sgn (const mpf_t OP)
+     Return +1 if OP > 0, 0 if OP = 0, and -1 if OP < 0.
+
+     This function is actually implemented as a macro.  It evaluates its

+7.7 Input and Output Functions
+==============================
+
+Functions that perform input from a stdio stream, and functions that
+output to a stdio stream, of 'mpf' numbers.  Passing a 'NULL' pointer
+for a STREAM argument to any of these functions will make them read from
+'stdin' and write to 'stdout', respectively.
+
+   When using any of these functions, it is a good idea to include
+'stdio.h' before 'gmp.h', since that will allow 'gmp.h' to define
+prototypes for these functions.
+
+   See also *note Formatted Output:: and *note Formatted Input::.
+
+ -- Function: size_t mpf_out_str (FILE *STREAM, int BASE, size_t
+          N_DIGITS, const mpf_t OP)
+     Print OP to STREAM, as a string of digits.  Return the number of
+     bytes written, or if an error occurred, return 0.
+
+     The mantissa is prefixed with an '0.' and is in the given BASE,
+     which may vary from 2 to 62 or from -2 to -36.  An exponent is then
+     printed, separated by an 'e', or if the base is greater than 10
+     then by an '@'.  The exponent is always in decimal.  The decimal
+     point follows the current locale, on systems providing
+     'localeconv'.
+
+     For BASE in the range 2..36, digits and lower-case letters are
+     used; for -2..-36, digits and upper-case letters are used; for
+     37..62, digits, upper-case letters, and lower-case letters (in that
+     significance order) are used.
+
+     Up to N_DIGITS will be printed from the mantissa, except that no
+     more digits than are accurately representable by OP will be
+     printed.  N_DIGITS can be 0 to select that accurate maximum.
+
+ -- Function: size_t mpf_inp_str (mpf_t ROP, FILE *STREAM, int BASE)
+     Read a string in base BASE from STREAM, and put the read float in
+     ROP.  The string is of the form 'M@N' or, if the base is 10 or
+     less, alternatively 'MeN'.  'M' is the mantissa and 'N' is the
+     exponent.  The mantissa is always in the specified base.  The
+     exponent is either in the specified base or, if BASE is negative,
+     in decimal.  The decimal point expected is taken from the current
+     locale, on systems providing 'localeconv'.
+
+     The argument BASE may be in the ranges 2 to 36, or -36 to -2.
+     Negative values are used to specify that the exponent is in
+     decimal.
+
+     Unlike the corresponding 'mpz' function, the base will not be
+     determined from the leading characters of the string if BASE is 0.
+     This is so that numbers like '0.23' are not interpreted as octal.
+
+     Return the number of bytes read, or if an error occurred, return 0.

+===========================
+
+ -- Function: void mpf_ceil (mpf_t ROP, const mpf_t OP)
+ -- Function: void mpf_floor (mpf_t ROP, const mpf_t OP)
+ -- Function: void mpf_trunc (mpf_t ROP, const mpf_t OP)
+     Set ROP to OP rounded to an integer.  'mpf_ceil' rounds to the next
+     higher integer, 'mpf_floor' to the next lower, and 'mpf_trunc' to
+     the integer towards zero.
+
+ -- Function: int mpf_integer_p (const mpf_t OP)
+     Return non-zero if OP is an integer.
+
+ -- Function: int mpf_fits_ulong_p (const mpf_t OP)
+ -- Function: int mpf_fits_slong_p (const mpf_t OP)
+ -- Function: int mpf_fits_uint_p (const mpf_t OP)
+ -- Function: int mpf_fits_sint_p (const mpf_t OP)
+ -- Function: int mpf_fits_ushort_p (const mpf_t OP)
+ -- Function: int mpf_fits_sshort_p (const mpf_t OP)
+     Return non-zero if OP would fit in the respective C data type, when
+     truncated to an integer.
+
+ -- Function: void mpf_urandomb (mpf_t ROP, gmp_randstate_t STATE,
+          mp_bitcnt_t NBITS)
+     Generate a uniformly distributed random float in ROP, such that 0
+     <= ROP < 1, with NBITS significant bits in the mantissa or less if
+     the precision of ROP is smaller.
+
+     The variable STATE must be initialized by calling one of the
+     'gmp_randinit' functions (*note Random State Initialization::)
+     before invoking this function.
+
+ -- Function: void mpf_random2 (mpf_t ROP, mp_size_t MAX_SIZE, mp_exp_t
+          EXP)
+     Generate a random float of at most MAX_SIZE limbs, with long
+     strings of zeros and ones in the binary representation.  The
+     exponent of the number is in the interval -EXP to EXP (in limbs).
+     This function is useful for testing functions and algorithms, since
+     these kind of random numbers have proven to be more likely to
+     trigger corner-case bugs.  Negative random numbers are generated
+     when MAX_SIZE is negative.

+8 Low-level Functions
+*********************
+
+This chapter describes low-level GMP functions, used to implement the
+high-level GMP functions, but also intended for time-critical user code.
+
+   These functions start with the prefix 'mpn_'.
+
+   The 'mpn' functions are designed to be as fast as possible, *not* to
+provide a coherent calling interface.  The different functions have
+somewhat similar interfaces, but there are variations that make them
+hard to use.  These functions do as little as possible apart from the
+real multiple precision computation, so that no time is spent on things
+that not all callers need.
+
+   A source operand is specified by a pointer to the least significant
+limb and a limb count.  A destination operand is specified by just a
+pointer.  It is the responsibility of the caller to ensure that the
+destination has enough space for storing the result.
+
+   With this way of specifying operands, it is possible to perform
+computations on subranges of an argument, and store the result into a
+subrange of a destination.
+
+   A common requirement for all functions is that each source area needs
+at least one limb.  No size argument may be zero.  Unless otherwise
+stated, in-place operations are allowed where source and destination are
+the same, but not where they only partly overlap.
+
+   The 'mpn' functions are the base for the implementation of the
+'mpz_', 'mpf_', and 'mpq_' functions.
+
+   This example adds the number beginning at S1P and the number
+beginning at S2P and writes the sum at DESTP.  All areas have N limbs.
+
+     cy = mpn_add_n (destp, s1p, s2p, n)
+
+   It should be noted that the 'mpn' functions make no attempt to
+identify high or low zero limbs on their operands, or other special
+forms.  On random data such cases will be unlikely and it'd be wasteful
+for every function to check every time.  An application knowing
+something about its data can take steps to trim or perhaps split its
+calculations.
+
+
+In the notation used below, a source operand is identified by the
+pointer to the least significant limb, and the limb count in braces.
+For example, {S1P, S1N}.
+
+ -- Function: mp_limb_t mpn_add_n (mp_limb_t *RP, const mp_limb_t *S1P,
+          const mp_limb_t *S2P, mp_size_t N)
+     Add {S1P, N} and {S2P, N}, and write the N least significant limbs
+     of the result to RP.  Return carry, either 0 or 1.
+
+     This is the lowest-level function for addition.  It is the
+     preferred function for addition, since it is written in assembly
+     for most CPUs.  For addition of a variable to itself (i.e., S1P
+     equals S2P) use 'mpn_lshift' with a count of 1 for optimal speed.
+
+ -- Function: mp_limb_t mpn_add_1 (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t N, mp_limb_t S2LIMB)
+     Add {S1P, N} and S2LIMB, and write the N least significant limbs of
+     the result to RP.  Return carry, either 0 or 1.
+
+ -- Function: mp_limb_t mpn_add (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t S1N, const mp_limb_t *S2P, mp_size_t S2N)
+     Add {S1P, S1N} and {S2P, S2N}, and write the S1N least significant
+     limbs of the result to RP.  Return carry, either 0 or 1.
+
+     This function requires that S1N is greater than or equal to S2N.
+
+ -- Function: mp_limb_t mpn_sub_n (mp_limb_t *RP, const mp_limb_t *S1P,
+          const mp_limb_t *S2P, mp_size_t N)
+     Subtract {S2P, N} from {S1P, N}, and write the N least significant
+     limbs of the result to RP.  Return borrow, either 0 or 1.
+
+     This is the lowest-level function for subtraction.  It is the
+     preferred function for subtraction, since it is written in assembly
+     for most CPUs.
+
+ -- Function: mp_limb_t mpn_sub_1 (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t N, mp_limb_t S2LIMB)
+     Subtract S2LIMB from {S1P, N}, and write the N least significant
+     limbs of the result to RP.  Return borrow, either 0 or 1.
+
+ -- Function: mp_limb_t mpn_sub (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t S1N, const mp_limb_t *S2P, mp_size_t S2N)
+     Subtract {S2P, S2N} from {S1P, S1N}, and write the S1N least
+     significant limbs of the result to RP.  Return borrow, either 0 or
+     1.
+
+     This function requires that S1N is greater than or equal to S2N.
+
+ -- Function: mp_limb_t mpn_neg (mp_limb_t *RP, const mp_limb_t *SP,
+          mp_size_t N)
+     Perform the negation of {SP, N}, and write the result to {RP, N}.
+     This is equivalent to calling 'mpn_sub_n' with a N-limb zero
+     minuend and passing {SP, N} as subtrahend.  Return borrow, either 0
+     or 1.
+
+ -- Function: void mpn_mul_n (mp_limb_t *RP, const mp_limb_t *S1P, const
+          mp_limb_t *S2P, mp_size_t N)
+     Multiply {S1P, N} and {S2P, N}, and write the 2*N-limb result to
+     RP.
+
+     The destination has to have space for 2*N limbs, even if the
+     product's most significant limb is zero.  No overlap is permitted
+     between the destination and either source.
+
+     If the two input operands are the same, use 'mpn_sqr'.
+
+ -- Function: mp_limb_t mpn_mul (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t S1N, const mp_limb_t *S2P, mp_size_t S2N)
+     Multiply {S1P, S1N} and {S2P, S2N}, and write the (S1N+S2N)-limb
+     result to RP.  Return the most significant limb of the result.
+
+     The destination has to have space for S1N + S2N limbs, even if the
+     product's most significant limb is zero.  No overlap is permitted
+     between the destination and either source.
+
+     This function requires that S1N is greater than or equal to S2N.
+
+ -- Function: void mpn_sqr (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t N)
+     Compute the square of {S1P, N} and write the 2*N-limb result to RP.
+
+     The destination has to have space for 2N limbs, even if the
+     result's most significant limb is zero.  No overlap is permitted
+     between the destination and the source.
+
+ -- Function: mp_limb_t mpn_mul_1 (mp_limb_t *RP, const mp_limb_t *S1P,
+          mp_size_t N, mp_limb_t S2LIMB)
+     Multiply {S1P, N} by S2LIMB, and write the N least significant
+     limbs of the product to RP.  Return the most significant limb of
+     the product.  {S1P, N} and {RP, N} are allowed to overlap provided
+     RP <= S1P.
+
+     This is a low-level function that is a building block for general
+     multiplication as well as other operations in GMP.  It is written
+     in assembly for most CPUs.
+
+     Don't call this function if S2LIMB is a power of 2; use
+     'mpn_lshift' with a count equal to the logarithm of S2LIMB instead,
+     for optimal speed.
+
+ -- Function: mp_limb_t mpn_addmul_1 (mp_limb_t *RP, const mp_limb_t
+          *S1P, mp_size_t N, mp_limb_t S2LIMB)
+     Multiply {S1P, N} and S2LIMB, and add the N least significant limbs
+     of the product to {RP, N} and write the result to RP.  Return the
+     most significant limb of the product, plus carry-out from the
+     addition.  {S1P, N} and {RP, N} are allowed to overlap provided RP
+     <= S1P.
+
+     This is a low-level function that is a building block for general
+     multiplication as well as other operations in GMP.  It is written
+     in assembly for most CPUs.
+
+ -- Function: mp_limb_t mpn_submul_1 (mp_limb_t *RP, const mp_limb_t
+          *S1P, mp_size_t N, mp_limb_t S2LIMB)
+     Multiply {S1P, N} and S2LIMB, and subtract the N least significant
+     limbs of the product from {RP, N} and write the result to RP.
+     Return the most significant limb of the product, plus borrow-out
+     from the subtraction.  {S1P, N} and {RP, N} are allowed to overlap
+     provided RP <= S1P.
+
+     This is a low-level function that is a building block for general
+     multiplication and division as well as other operations in GMP.  It
+     is written in assembly for most CPUs.
+
+ -- Function: void mpn_tdiv_qr (mp_limb_t *QP, mp_limb_t *RP, mp_size_t
+          QXN, const mp_limb_t *NP, mp_size_t NN, const mp_limb_t *DP,
+          mp_size_t DN)
+     Divide {NP, NN} by {DP, DN} and put the quotient at {QP, NN-DN+1}
+     and the remainder at {RP, DN}.  The quotient is rounded towards 0.
+
+     No overlap is permitted between arguments, except that NP might
+     equal RP.  The dividend size NN must be greater than or equal to
+     divisor size DN.  The most significant limb of the divisor must be
+     non-zero.  The QXN operand must be zero.
+
+ -- Function: mp_limb_t mpn_divrem (mp_limb_t *R1P, mp_size_t QXN,
+          mp_limb_t *RS2P, mp_size_t RS2N, const mp_limb_t *S3P,
+          mp_size_t S3N)
+     [This function is obsolete.  Please call 'mpn_tdiv_qr' instead for
+     best performance.]
+
+     Divide {RS2P, RS2N} by {S3P, S3N}, and write the quotient at R1P,
+     with the exception of the most significant limb, which is returned.
+     The remainder replaces the dividend at RS2P; it will be S3N limbs
+     long (i.e., as many limbs as the divisor).
+
+     In addition to an integer quotient, QXN fraction limbs are
+     developed, and stored after the integral limbs.  For most usages,
+     QXN will be zero.
+
+     It is required that RS2N is greater than or equal to S3N.  It is
+     required that the most significant bit of the divisor is set.
+
+     If the quotient is not needed, pass RS2P + S3N as R1P.  Aside from
+     that special case, no overlap between arguments is permitted.
+
+     Return the most significant limb of the quotient, either 0 or 1.
+
+     The area at R1P needs to be RS2N - S3N + QXN limbs large.
+
+ -- Function: mp_limb_t mpn_divrem_1 (mp_limb_t *R1P, mp_size_t QXN,
+          mp_limb_t *S2P, mp_size_t S2N, mp_limb_t S3LIMB)
+ -- Macro: mp_limb_t mpn_divmod_1 (mp_limb_t *R1P, mp_limb_t *S2P,
+          mp_size_t S2N, mp_limb_t S3LIMB)
+     Divide {S2P, S2N} by S3LIMB, and write the quotient at R1P.  Return
+     the remainder.
+
+     The integer quotient is written to {R1P+QXN, S2N} and in addition
+     QXN fraction limbs are developed and written to {R1P, QXN}.  Either
+     or both S2N and QXN can be zero.  For most usages, QXN will be
+     zero.
+
+     'mpn_divmod_1' exists for upward source compatibility and is simply
+     a macro calling 'mpn_divrem_1' with a QXN of 0.
+
+     The areas at R1P and S2P have to be identical or completely
+     separate, not partially overlapping.
+
+ -- Function: mp_limb_t mpn_divmod (mp_limb_t *R1P, mp_limb_t *RS2P,
+          mp_size_t RS2N, const mp_limb_t *S3P, mp_size_t S3N)
+     [This function is obsolete.  Please call 'mpn_tdiv_qr' instead for
+     best performance.]
+
+ -- Function: void mpn_divexact_1 (mp_limb_t * RP, const mp_limb_t * SP,
+          mp_size_t N, mp_limb_t D)
+     Divide {SP, N} by D, expecting it to divide exactly, and writing
+     the result to {RP, N}.  If D doesn't divide exactly, the value
+     written to {RP, N} is undefined.  The areas at RP and SP have to be
+     identical or completely separate, not partially overlapping.
+
+ -- Macro: mp_limb_t mpn_divexact_by3 (mp_limb_t *RP, mp_limb_t *SP,
+          mp_size_t N)
+ -- Function: mp_limb_t mpn_divexact_by3c (mp_limb_t *RP, mp_limb_t *SP,
+          mp_size_t N, mp_limb_t CARRY)
+     Divide {SP, N} by 3, expecting it to divide exactly, and writing
+     the result to {RP, N}.  If 3 divides exactly, the return value is
+     zero and the result is the quotient.  If not, the return value is
+     non-zero and the result won't be anything useful.
+
+     'mpn_divexact_by3c' takes an initial carry parameter, which can be
+     the return value from a previous call, so a large calculation can
+     be done piece by piece from low to high.  'mpn_divexact_by3' is
+     simply a macro calling 'mpn_divexact_by3c' with a 0 carry
+     parameter.
+
+     These routines use a multiply-by-inverse and will be faster than
+     'mpn_divrem_1' on CPUs with fast multiplication but slow division.
+
+     The source a, result q, size n, initial carry i, and return value c
+     satisfy c*b^n + a-i = 3*q, where b=2^GMP_NUMB_BITS. The return c is
+     always 0, 1 or 2, and the initial carry i must also be 0, 1 or 2
+     (these are both borrows really).  When c=0 clearly q=(a-i)/3.  When
+     c!=0, the remainder (a-i) mod 3 is given by 3-c, because b == 1 mod
+     3 (when 'mp_bits_per_limb' is even, which is always so currently).
+
+ -- Function: mp_limb_t mpn_mod_1 (const mp_limb_t *S1P, mp_size_t S1N,
+          mp_limb_t S2LIMB)
+     Divide {S1P, S1N} by S2LIMB, and return the remainder.  S1N can be
+     zero.
+
+ -- Function: mp_limb_t mpn_lshift (mp_limb_t *RP, const mp_limb_t *SP,
+          mp_size_t N, unsigned int COUNT)
+     Shift {SP, N} left by COUNT bits, and write the result to {RP, N}.
+     The bits shifted out at the left are returned in the least
+     significant COUNT bits of the return value (the rest of the return
+     value is zero).
+
+     COUNT must be in the range 1 to mp_bits_per_limb-1.  The regions
+     {SP, N} and {RP, N} may overlap, provided RP >= SP.
+
+     This function is written in assembly for most CPUs.
+
+ -- Function: mp_limb_t mpn_rshift (mp_limb_t *RP, const mp_limb_t *SP,
+          mp_size_t N, unsigned int COUNT)
+     Shift {SP, N} right by COUNT bits, and write the result to {RP, N}.
+     The bits shifted out at the right are returned in the most
+     significant COUNT bits of the return value (the rest of the return
+     value is zero).
+
+     COUNT must be in the range 1 to mp_bits_per_limb-1.  The regions
+     {SP, N} and {RP, N} may overlap, provided RP <= SP.
+
+     This function is written in assembly for most CPUs.
+
+ -- Function: int mpn_cmp (const mp_limb_t *S1P, const mp_limb_t *S2P,
+          mp_size_t N)
+     Compare {S1P, N} and {S2P, N} and return a positive value if S1 >
+     S2, 0 if they are equal, or a negative value if S1 < S2.
+
+ -- Function: int mpn_zero_p (const mp_limb_t *SP, mp_size_t N)
+     Test {SP, N} and return 1 if the operand is zero, 0 otherwise.
+
+ -- Function: mp_size_t mpn_gcd (mp_limb_t *RP, mp_limb_t *XP, mp_size_t
+          XN, mp_limb_t *YP, mp_size_t YN)
+     Set {RP, RETVAL} to the greatest common divisor of {XP, XN} and
+     {YP, YN}.  The result can be up to YN limbs, the return value is
+     the actual number produced.  Both source operands are destroyed.
+
+     It is required that XN >= YN > 0, the most significant limb of {YP,
+     YN} must be non-zero, and at least one of the two operands must be
+     odd.  No overlap is permitted between {XP, XN} and {YP, YN}.
+
+ -- Function: mp_limb_t mpn_gcd_1 (const mp_limb_t *XP, mp_size_t XN,
+          mp_limb_t YLIMB)
+     Return the greatest common divisor of {XP, XN} and YLIMB.  Both
+     operands must be non-zero.
+
+ -- Function: mp_size_t mpn_gcdext (mp_limb_t *GP, mp_limb_t *SP,
+          mp_size_t *SN, mp_limb_t *UP, mp_size_t UN, mp_limb_t *VP,
+          mp_size_t VN)
+     Let U be defined by {UP, UN} and let V be defined by {VP, VN}.
+
+     Compute the greatest common divisor G of U and V. Compute a
+     cofactor S such that G = US + VT. The second cofactor T is not
+     computed but can easily be obtained from (G - U*S) / V (the
+     division will be exact).  It is required that UN >= VN > 0, and the
+     most significant limb of {VP, VN} must be non-zero.
+
+     S satisfies S = 1 or abs(S) < V / (2 G). S = 0 if and only if V
+     divides U (i.e., G = V).
+
+     Store G at GP and let the return value define its limb count.
+     Store S at SP and let |*SN| define its limb count.  S can be
+     negative; when this happens *SN will be negative.  The area at GP
+     should have room for VN limbs and the area at SP should have room
+     for VN+1 limbs.
+
+     Both source operands are destroyed.
+
+     Compatibility notes: GMP 4.3.0 and 4.3.1 defined S less strictly.
+     Earlier as well as later GMP releases define S as described here.
+     GMP releases before GMP 4.3.0 required additional space for both
+     input and output areas.  More precisely, the areas {UP, UN+1} and
+     {VP, VN+1} were destroyed (i.e. the operands plus an extra limb
+     past the end of each), and the areas pointed to by GP and SP should
+     each have room for UN+1 limbs.
+
+ -- Function: mp_size_t mpn_sqrtrem (mp_limb_t *R1P, mp_limb_t *R2P,
+          const mp_limb_t *SP, mp_size_t N)
+     Compute the square root of {SP, N} and put the result at {R1P,
+     ceil(N/2)} and the remainder at {R2P, RETVAL}.  R2P needs space for
+     N limbs, but the return value indicates how many are produced.
+
+     The most significant limb of {SP, N} must be non-zero.  The areas
+     {R1P, ceil(N/2)} and {SP, N} must be completely separate.  The
+     areas {R2P, N} and {SP, N} must be either identical or completely
+     separate.
+
+     If the remainder is not wanted then R2P can be 'NULL', and in this
+     case the return value is zero or non-zero according to whether the
+     remainder would have been zero or non-zero.
+
+     A return value of zero indicates a perfect square.  See also
+     'mpn_perfect_square_p'.
+
+ -- Function: size_t mpn_sizeinbase (const mp_limb_t *XP, mp_size_t N,
+          int BASE)
+     Return the size of {XP,N} measured in number of digits in the given
+     BASE.  BASE can vary from 2 to 62.  Requires N > 0 and XP[N-1] > 0.
+     The result will be either exact or 1 too big.  If BASE is a power
+     of 2, the result is always exact.
+
+ -- Function: mp_size_t mpn_get_str (unsigned char *STR, int BASE,
+          mp_limb_t *S1P, mp_size_t S1N)
+     Convert {S1P, S1N} to a raw unsigned char array at STR in base
+     BASE, and return the number of characters produced.  There may be
+     leading zeros in the string.  The string is not in ASCII; to
+     convert it to printable format, add the ASCII codes for '0' or 'A',
+     depending on the base and range.  BASE can vary from 2 to 256.
+
+     The most significant limb of the input {S1P, S1N} must be non-zero.
+     The input {S1P, S1N} is clobbered, except when BASE is a power of
+     2, in which case it's unchanged.
+
+     The area at STR has to have space for the largest possible number
+     represented by a S1N long limb array, plus one extra character.
+
+ -- Function: mp_size_t mpn_set_str (mp_limb_t *RP, const unsigned char
+          *STR, size_t STRSIZE, int BASE)
+     Convert bytes {STR,STRSIZE} in the given BASE to limbs at RP.
+
+     STR[0] is the most significant input byte and STR[STRSIZE-1] is the
+     least significant input byte.  Each byte should be a value in the
+     range 0 to BASE-1, not an ASCII character.  BASE can vary from 2 to
+     256.
+
+     The converted value is {RP,RN} where RN is the return value.  If
+     the most significant input byte STR[0] is non-zero, then RP[RN-1]
+     will be non-zero, else RP[RN-1] and some number of subsequent limbs
+     may be zero.
+
+     The area at RP has to have space for the largest possible number
+     with STRSIZE digits in the chosen base, plus one extra limb.
+
+     The input must have at least one byte, and no overlap is permitted
+     between {STR,STRSIZE} and the result at RP.
+
+ -- Function: mp_bitcnt_t mpn_scan0 (const mp_limb_t *S1P, mp_bitcnt_t
+          BIT)
+     Scan S1P from bit position BIT for the next clear bit.
+
+     It is required that there be a clear bit within the area at S1P at
+     or beyond bit position BIT, so that the function has something to
+     return.
+
+ -- Function: mp_bitcnt_t mpn_scan1 (const mp_limb_t *S1P, mp_bitcnt_t
+          BIT)
+     Scan S1P from bit position BIT for the next set bit.
+
+     It is required that there be a set bit within the area at S1P at or
+     beyond bit position BIT, so that the function has something to
+     return.
+
+ -- Function: void mpn_random (mp_limb_t *R1P, mp_size_t R1N)
+ -- Function: void mpn_random2 (mp_limb_t *R1P, mp_size_t R1N)
+     Generate a random number of length R1N and store it at R1P.  The
+     most significant limb is always non-zero.  'mpn_random' generates
+     uniformly distributed limb data, 'mpn_random2' generates long
+     strings of zeros and ones in the binary representation.
+
+     'mpn_random2' is intended for testing the correctness of the 'mpn'
+     routines.
+
+ -- Function: mp_bitcnt_t mpn_popcount (const mp_limb_t *S1P, mp_size_t
+          N)

+
+ -- Function: mp_bitcnt_t mpn_hamdist (const mp_limb_t *S1P, const
+          mp_limb_t *S2P, mp_size_t N)
+     Compute the hamming distance between {S1P, N} and {S2P, N}, which
+     is the number of bit positions where the two operands have
+     different bit values.
+
+ -- Function: int mpn_perfect_square_p (const mp_limb_t *S1P, mp_size_t
+          N)
+     Return non-zero iff {S1P, N} is a perfect square.  The most
+     significant limb of the input {S1P, N} must be non-zero.
+
+ -- Function: void mpn_and_n (mp_limb_t *RP, const mp_limb_t *S1P, const

+
+8.1 Low-level functions for cryptography
+========================================
+
+The functions prefixed with 'mpn_sec_' and 'mpn_cnd_' are designed to
+perform the exact same low-level operations and have the same cache
+access patterns for any two same-size arguments, assuming that function
+arguments are placed at the same position and that the machine state is
+identical upon function entry.  These functions are intended for
+cryptographic purposes, where resilience to side-channel attacks is
+desired.
+
+   These functions are less efficient than their "leaky" counterparts;
+their performance for operands of the sizes typically used for
+cryptographic applications is between 15% and 100% worse.  For larger
+operands, these functions might be inadequate, since they rely on
+asymptotically elementary algorithms.
+
+   These functions do not make any explicit allocations.  Those of these
+functions that need scratch space accept a scratch space operand.  This
+convention allows callers to keep sensitive data in designated memory
+areas.  Note however that compilers may choose to spill scalar values
+used within these functions to their stack frame and that such scalars
+may contain sensitive data.
+
+   In addition to these specially crafted functions, the following 'mpn'
+functions are naturally side-channel resistant: 'mpn_add_n',
+'mpn_sub_n', 'mpn_lshift', 'mpn_rshift', 'mpn_zero', 'mpn_copyi',
+'mpn_copyd', 'mpn_com', and the logical function ('mpn_and_n', etc).
+
+   There are some exceptions from the side-channel resilience: (1) Some
+assembly implementations of 'mpn_lshift' identify shift-by-one as a
+special case.  This is a problem iff the shift count is a function of
+sensitive data.  (2) Alpha ev6 and Pentium4 using 64-bit limbs have
+leaky 'mpn_add_n' and 'mpn_sub_n'.  (3) Alpha ev6 has a leaky
+'mpn_mul_1' which also makes 'mpn_sec_mul' on those systems unsafe.
+
+ -- Function: mp_limb_t mpn_cnd_add_n (mp_limb_t CND, mp_limb_t *RP,
+          const mp_limb_t *S1P, const mp_limb_t *S2P, mp_size_t N)
+ -- Function: mp_limb_t mpn_cnd_sub_n (mp_limb_t CND, mp_limb_t *RP,
+          const mp_limb_t *S1P, const mp_limb_t *S2P, mp_size_t N)
+     These functions do conditional addition and subtraction.  If CND is
+     non-zero, they produce the same result as a regular 'mpn_add_n' or
+     'mpn_sub_n', and if CND is zero, they copy {S1P,N} to the result
+     area and return zero.  The functions are designed to have timing
+     and memory access patterns depending only on size and location of
+     the data areas, but independent of the condition CND.  Like for
+     'mpn_add_n' and 'mpn_sub_n', on most machines, the timing will also
+     be independent of the actual limb values.
+
+ -- Function: mp_limb_t mpn_sec_add_1 (mp_limb_t *RP, const mp_limb_t
+          *AP, mp_size_t N, mp_limb_t B, mp_limb_t *TP)
+ -- Function: mp_limb_t mpn_sec_sub_1 (mp_limb_t *RP, const mp_limb_t
+          *AP, mp_size_t N, mp_limb_t B, mp_limb_t *TP)
+     Set R to A + B or A - B, respectively, where R = {RP,N}, A =
+     {AP,N}, and B is a single limb.  Returns carry.
+
+     These functions take O(N) time, unlike the leaky functions
+     'mpn_add_1' which are O(1) on average.  They require scratch space
+     of 'mpn_sec_add_1_itch(N)' and 'mpn_sec_sub_1_itch(N)' limbs,
+     respectively, to be passed in the TP parameter.  The scratch space
+     requirements are guaranteed to be at most N limbs, and increase
+     monotonously in the operand size.
+
+ -- Function: void mpn_cnd_swap (mp_limb_t CND, volatile mp_limb_t *AP,
+          volatile mp_limb_t *BP, mp_size_t N)
+     If CND is non-zero, swaps the contents of the areas {AP,N} and
+     {BP,N}.  Otherwise, the areas are left unmodified.  Implemented
+     using logical operations on the limbs, with the same memory
+     accesses independent of the value of CND.
+
+ -- Function: void mpn_sec_mul (mp_limb_t *RP, const mp_limb_t *AP,

+          *TP)
+ -- Function: mp_size_t mpn_sec_mul_itch (mp_size_t AN, mp_size_t BN)
+     Set R to A * B, where A = {AP,AN}, B = {BP,BN}, and R = {RP,AN+BN}.
+
+     It is required that AN >= BN > 0.
+
+     No overlapping between R and the input operands is allowed.  For A
+     = B, use 'mpn_sec_sqr' for optimal performance.
+
+     This function requires scratch space of 'mpn_sec_mul_itch(AN, BN)'
+     limbs to be passed in the TP parameter.  The scratch space
+     requirements are guaranteed to increase monotonously in the operand
+     sizes.
+
+ -- Function: void mpn_sec_sqr (mp_limb_t *RP, const mp_limb_t *AP,
+          mp_size_t AN, mp_limb_t *TP)
+ -- Function: mp_size_t mpn_sec_sqr_itch (mp_size_t AN)
+     Set R to A^2, where A = {AP,AN}, and R = {RP,2AN}.
+
+     It is required that AN > 0.
+
+     No overlapping between R and the input operands is allowed.
+
+     This function requires scratch space of 'mpn_sec_sqr_itch(AN)'

+          mp_limb_t *MP, mp_size_t N, mp_limb_t *TP)
+ -- Function: mp_size_t mpn_sec_powm_itch (mp_size_t BN, mp_bitcnt_t
+          ENB, size_t N)
+     Set R to (B raised to E) modulo M, where R = {RP,N}, M = {MP,N},
+     and E = {EP,ceil(ENB / 'GMP\_NUMB\_BITS')}.
+
+     It is required that B > 0, that M > 0 is odd, and that E < 2^ENB,
+     with ENB > 0.
+
+     No overlapping between R and the input operands is allowed.
+
+     This function requires scratch space of 'mpn_sec_powm_itch(BN, ENB,
+     N)' limbs to be passed in the TP parameter.  The scratch space
+     requirements are guaranteed to increase monotonously in the operand
+     sizes.
+
+ -- Function: void mpn_sec_tabselect (mp_limb_t *RP, const mp_limb_t
+          *TAB, mp_size_t N, mp_size_t NENTS, mp_size_t WHICH)
+     Select entry WHICH from table TAB, which has NENTS entries, each N
+     limbs.  Store the selected entry at RP.
+
+     This function reads the entire table to avoid side-channel
+     information leaks.
+
+ -- Function: mp_limb_t mpn_sec_div_qr (mp_limb_t *QP, mp_limb_t *NP,
+          mp_size_t NN, const mp_limb_t *DP, mp_size_t DN, mp_limb_t
+          *TP)
+ -- Function: mp_size_t mpn_sec_div_qr_itch (mp_size_t NN, mp_size_t DN)
+
+     Set Q to the truncated quotient N / D and R to N modulo D, where N
+     = {NP,NN}, D = {DP,DN}, Q's most significant limb is the function
+     return value and the remaining limbs are {QP,NN-DN}, and R =
+     {NP,DN}.
+
+     It is required that NN >= DN >= 1, and that DP[DN-1] != 0.  This
+     does not imply that N >= D since N might be zero-padded.
+
+     Note the overlapping between N and R.  No other operand overlapping
+     is allowed.  The entire space occupied by N is overwritten.
+
+     This function requires scratch space of 'mpn_sec_div_qr_itch(NN,
+     DN)' limbs to be passed in the TP parameter.
+
+ -- Function: void mpn_sec_div_r (mp_limb_t *NP, mp_size_t NN, const

+ -- Function: mp_size_t mpn_sec_div_r_itch (mp_size_t NN, mp_size_t DN)
+
+     Set R to N modulo D, where N = {NP,NN}, D = {DP,DN}, and R =
+     {NP,DN}.
+
+     It is required that NN >= DN >= 1, and that DP[DN-1] != 0.  This
+     does not imply that N >= D since N might be zero-padded.
+
+     Note the overlapping between N and R.  No other operand overlapping
+     is allowed.  The entire space occupied by N is overwritten.
+
+     This function requires scratch space of 'mpn_sec_div_r_itch(NN,

+ -- Function: mp_size_t mpn_sec_invert_itch (mp_size_t N)
+     Set R to the inverse of A modulo M, where R = {RP,N}, A = {AP,N},
+     and M = {MP,N}.  *This function's interface is preliminary.*
+
+     If an inverse exists, return 1, otherwise return 0 and leave R
+     undefined.  In either case, the input A is destroyed.
+
+     It is required that M is odd, and that NBCNT >= ceil(\log(A+1)) +
+     ceil(\log(M+1)).  A safe choice is NBCNT = 2 * N * GMP_NUMB_BITS,
+     but a smaller value might improve performance if M or A are known
+     to have leading zero bits.
+
+     This function requires scratch space of 'mpn_sec_invert_itch(N)'
+     limbs to be passed in the TP parameter.
+
+
+8.2 Nails
+=========
+
+*Everything in this section is highly experimental and may disappear or
+be subject to incompatible changes in a future version of GMP.*
+
+   Nails are an experimental feature whereby a few bits are left unused
+at the top of each 'mp_limb_t'.  This can significantly improve carry
+handling on some processors.
+
+   All the 'mpn' functions accepting limb data will expect the nail bits
+to be zero on entry, and will return data with the nails similarly all
+zero.  This applies both to limb vectors and to single limb arguments.
+
+   Nails can be enabled by configuring with '--enable-nails'.  By
+default the number of bits will be chosen according to what suits the
+host processor, but a particular number can be selected with
+'--enable-nails=N'.
+
+   At the mpn level, a nail build is neither source nor binary
+compatible with a non-nail build, strictly speaking.  But programs
+acting on limbs only through the mpn functions are likely to work
+equally well with either build, and judicious use of the definitions
+below should make any program compatible with either build, at the
+source level.
+
+   For the higher level routines, meaning 'mpz' etc, a nail build should
+be fully source and binary compatible with a non-nail build.
+
+ -- Macro: GMP_NAIL_BITS
+ -- Macro: GMP_NUMB_BITS
+ -- Macro: GMP_LIMB_BITS
+     'GMP_NAIL_BITS' is the number of nail bits, or 0 when nails are not
+     in use.  'GMP_NUMB_BITS' is the number of data bits in a limb.
+     'GMP_LIMB_BITS' is the total number of bits in an 'mp_limb_t'.  In
+     all cases
+
+          GMP_LIMB_BITS == GMP_NAIL_BITS + GMP_NUMB_BITS
+
+ -- Macro: GMP_NAIL_MASK
+ -- Macro: GMP_NUMB_MASK
+     Bit masks for the nail and number parts of a limb.  'GMP_NAIL_MASK'
+     is 0 when nails are not in use.
+
+     'GMP_NAIL_MASK' is not often needed, since the nail part can be
+     obtained with 'x >> GMP_NUMB_BITS', and that means one less large
+     constant, which can help various RISC chips.
+
+ -- Macro: GMP_NUMB_MAX
+     The maximum value that can be stored in the number part of a limb.
+     This is the same as 'GMP_NUMB_MASK', but can be used for clarity
+     when doing comparisons rather than bit-wise operations.
+
+   The term "nails" comes from finger or toe nails, which are at the
+ends of a limb (arm or leg).  "numb" is short for number, but is also
+how the developers felt after trying for a long time to come up with
+sensible names for these things.
+
+   In the future (the distant future most likely) a non-zero nail might
+be permitted, giving non-unique representations for numbers in a limb
+vector.  This would help vector processors since carries would only ever
+need to propagate one or two limbs.

+9 Random Number Functions
+*************************
+
+Sequences of pseudo-random numbers in GMP are generated using a variable
+of type 'gmp_randstate_t', which holds an algorithm selection and a
+current state.  Such a variable must be initialized by a call to one of
+the 'gmp_randinit' functions, and can be seeded with one of the
+'gmp_randseed' functions.
+
+   The functions actually generating random numbers are described in
+*note Integer Random Numbers::, and *note Miscellaneous Float
+Functions::.
+
+   The older style random number functions don't accept a
+'gmp_randstate_t' parameter but instead share a global variable of that
+type.  They use a default algorithm and are currently not seeded (though
+perhaps that will change in the future).  The new functions accepting a
+'gmp_randstate_t' are recommended for applications that care about
+randomness.

+
+9.1 Random State Initialization
+===============================
+
+ -- Function: void gmp_randinit_default (gmp_randstate_t STATE)
+     Initialize STATE with a default algorithm.  This will be a
+     compromise between speed and randomness, and is recommended for
+     applications with no special requirements.  Currently this is
+     'gmp_randinit_mt'.
+
+ -- Function: void gmp_randinit_mt (gmp_randstate_t STATE)
+     Initialize STATE for a Mersenne Twister algorithm.  This algorithm
+     is fast and has good randomness properties.
+
+ -- Function: void gmp_randinit_lc_2exp (gmp_randstate_t STATE, const
+          mpz_t A, unsigned long C, mp_bitcnt_t M2EXP)
+     Initialize STATE with a linear congruential algorithm X = (A*X + C)
+     mod 2^M2EXP.
+
+     The low bits of X in this algorithm are not very random.  The least
+     significant bit will have a period no more than 2, and the second
+     bit no more than 4, etc.  For this reason only the high half of
+     each X is actually used.
+
+     When a random number of more than M2EXP/2 bits is to be generated,
+     multiple iterations of the recurrence are used and the results
+     concatenated.
+
+ -- Function: int gmp_randinit_lc_2exp_size (gmp_randstate_t STATE,
+          mp_bitcnt_t SIZE)
+     Initialize STATE for a linear congruential algorithm as per
+     'gmp_randinit_lc_2exp'.  A, C and M2EXP are selected from a table,
+     chosen so that SIZE bits (or more) of each X will be used, i.e.
+     M2EXP/2 >= SIZE.
+
+     If successful the return value is non-zero.  If SIZE is bigger than
+     the table data provides then the return value is zero.  The maximum
+     SIZE currently supported is 128.
+
+ -- Function: void gmp_randinit_set (gmp_randstate_t ROP,
+          gmp_randstate_t OP)
+     Initialize ROP with a copy of the algorithm and state from OP.
+
+ -- Function: void gmp_randinit (gmp_randstate_t STATE,
+          gmp_randalg_t ALG, ...)
+     *This function is obsolete.*
+
+     Initialize STATE with an algorithm selected by ALG.  The only
+     choice is 'GMP_RAND_ALG_LC', which is 'gmp_randinit_lc_2exp_size'
+     described above.  A third parameter of type 'unsigned long' is
+     required, this is the SIZE for that function.
+     'GMP_RAND_ALG_DEFAULT' or 0 are the same as 'GMP_RAND_ALG_LC'.
+
+     'gmp_randinit' sets bits in the global variable 'gmp_errno' to
+     indicate an error.  'GMP_ERROR_UNSUPPORTED_ARGUMENT' if ALG is
+     unsupported, or 'GMP_ERROR_INVALID_ARGUMENT' if the SIZE parameter
+     is too big.  It may be noted this error reporting is not thread
+     safe (a good reason to use 'gmp_randinit_lc_2exp_size' instead).
+
+ -- Function: void gmp_randclear (gmp_randstate_t STATE)
+     Free all memory occupied by STATE.

+9.2 Random State Seeding
+========================
+
+ -- Function: void gmp_randseed (gmp_randstate_t STATE, const mpz_t
+          SEED)
+ -- Function: void gmp_randseed_ui (gmp_randstate_t STATE,
+          unsigned long int SEED)
+     Set an initial seed value into STATE.
+
+     The size of a seed determines how many different sequences of
+     random numbers that it's possible to generate.  The "quality" of
+     the seed is the randomness of a given seed compared to the previous
+     seed used, and this affects the randomness of separate number
+     sequences.  The method for choosing a seed is critical if the
+     generated numbers are to be used for important applications, such
+     as generating cryptographic keys.
+
+     Traditionally the system time has been used to seed, but care needs
+     to be taken with this.  If an application seeds often and the
+     resolution of the system clock is low, then the same sequence of
+     numbers might be repeated.  Also, the system time is quite easy to
+     guess, so if unpredictability is required then it should definitely
+     not be the only source for the seed value.  On some systems there's
+     a special device '/dev/random' which provides random data better
+     suited for use as a seed.

+
+10.1 Format Strings
+===================
+
+'gmp_printf' and friends accept format strings similar to the standard C
+'printf' (*note Formatted Output: (libc)Formatted Output.).  A format
+specification is of the form
+
+     % [flags] [width] [.[precision]] [type] conv
+
+   GMP adds types 'Z', 'Q' and 'F' for 'mpz_t', 'mpq_t' and 'mpf_t'
+respectively, 'M' for 'mp_limb_t', and 'N' for an 'mp_limb_t' array.
+'Z', 'Q', 'M' and 'N' behave like integers.  'Q' will print a '/' and a
+denominator, if needed.  'F' behaves like a float.  For example,
+
+     mpz_t z;
+     gmp_printf ("%s is an mpz %Zd\n", "here", z);
+
+     mpq_t q;
+     gmp_printf ("a hex rational: %#40Qx\n", q);
+
+     mpf_t f;
+     int   n;
+     gmp_printf ("fixed point mpf %.*Ff with %d digits\n", n, f, n);
+
+     mp_limb_t l;
+     gmp_printf ("limb %Mu\n", l);
+
+     const mp_limb_t *ptr;
+     mp_size_t       size;
+     gmp_printf ("limb array %Nx\n", ptr, size);
+
+   For 'N' the limbs are expected least significant first, as per the
+'mpn' functions (*note Low-level Functions::).  A negative size can be
+given to print the value as a negative.
+
+   All the standard C 'printf' types behave the same as the C library
+'printf', and can be freely intermixed with the GMP extensions.  In the
+current implementation the standard parts of the format string are
+simply handed to 'printf' and only the GMP extensions handled directly.
+
+   The flags accepted are as follows.  GLIBC style ' is only for the
+standard C types (not the GMP types), and only if the C library supports
+it.
+
+     0         pad with zeros (rather than spaces)
+     #         show the base with '0x', '0X' or '0'
+     +         always show a sign
+     (space)   show a space or a '-' sign
+     '         group digits, GLIBC style (not GMP
+               types)
+
+   The optional width and precision can be given as a number within the
+format string, or as a '*' to take an extra parameter of type 'int', the
+same as the standard 'printf'.
+
+   The standard types accepted are as follows.  'h' and 'l' are
+portable, the rest will depend on the compiler (or include files) for
+the type and the C library for the output.
+
+     h         short
+     hh        char
+     j         intmax_t or uintmax_t
+     l         long or wchar_t
+     ll        long long
+     L         long double
+     q         quad_t or u_quad_t
+     t         ptrdiff_t
+     z         size_t
+
+The GMP types are
+
+     F         mpf_t, float conversions
+     Q         mpq_t, integer conversions
+     M         mp_limb_t, integer conversions
+     N         mp_limb_t array, integer conversions
+     Z         mpz_t, integer conversions
+
+   The conversions accepted are as follows.  'a' and 'A' are always
+supported for 'mpf_t' but depend on the C library for standard C float
+types.  'm' and 'p' depend on the C library.
+
+     a A       hex floats, C99 style
+     c         character
+     d         decimal integer
+     e E       scientific format float
+     f         fixed point float
+     i         same as d
+     g G       fixed or scientific float
+     m         'strerror' string, GLIBC style
+     n         store characters written so far
+     o         octal integer
+     p         pointer
+     s         string
+     u         unsigned integer
+     x X       hex integer
+
+   'o', 'x' and 'X' are unsigned for the standard C types, but for types
+'Z', 'Q' and 'N' they are signed.  'u' is not meaningful for 'Z', 'Q'
+and 'N'.
+
+   'M' is a proxy for the C library 'l' or 'L', according to the size of
+'mp_limb_t'.  Unsigned conversions will be usual, but a signed
+conversion can be used and will interpret the value as a twos complement
+negative.
+
+   'n' can be used with any type, even the GMP types.
+
+   Other types or conversions that might be accepted by the C library
+'printf' cannot be used through 'gmp_printf', this includes for instance
+extensions registered with GLIBC 'register_printf_function'.  Also
+currently there's no support for POSIX '$' style numbered arguments
+(perhaps this will be added in the future).
+
+   The precision field has its usual meaning for integer 'Z' and float
+'F' types, but is currently undefined for 'Q' and should not be used
+with that.
+
+   'mpf_t' conversions only ever generate as many digits as can be
+accurately represented by the operand, the same as 'mpf_get_str' does.
+Zeros will be used if necessary to pad to the requested precision.  This
+happens even for an 'f' conversion of an 'mpf_t' which is an integer,
+for instance 2^1024 in an 'mpf_t' of 128 bits precision will only
+produce about 40 digits, then pad with zeros to the decimal point.  An
+empty precision field like '%.Fe' or '%.Ff' can be used to specifically
+request just the significant digits.  Without any dot and thus no
+precision field, a precision value of 6 will be used.  Note that these
+rules mean that '%Ff', '%.Ff', and '%.0Ff' will all be different.
+
+   The decimal point character (or string) is taken from the current
+locale settings on systems which provide 'localeconv' (*note Locales and
+Internationalization: (libc)Locales.).  The C library will normally do
+the same for standard float output.
+
+   The format string is only interpreted as plain 'char's, multibyte
+characters are not recognised.  Perhaps this will change in the future.

+
+10.2 Functions
+==============
+
+Each of the following functions is similar to the corresponding C
+library function.  The basic 'printf' forms take a variable argument
+list.  The 'vprintf' forms take an argument pointer, see *note Variadic
+Functions: (libc)Variadic Functions, or 'man 3 va_start'.
+
+   It should be emphasised that if a format string is invalid, or the
+arguments don't match what the format specifies, then the behaviour of
+any of these functions will be unpredictable.  GCC format string
+checking is not available, since it doesn't recognise the GMP
+extensions.
+
+   The file based functions 'gmp_printf' and 'gmp_fprintf' will return
+-1 to indicate a write error.  Output is not "atomic", so partial output
+may be produced if a write error occurs.  All the functions can return
+-1 if the C library 'printf' variant in use returns -1, but this
+shouldn't normally occur.
+
+ -- Function: int gmp_printf (const char *FMT, ...)
+ -- Function: int gmp_vprintf (const char *FMT, va_list AP)
+     Print to the standard output 'stdout'.  Return the number of
+     characters written, or -1 if an error occurred.
+
+ -- Function: int gmp_fprintf (FILE *FP, const char *FMT, ...)
+ -- Function: int gmp_vfprintf (FILE *FP, const char *FMT, va_list AP)
+     Print to the stream FP.  Return the number of characters written,
+     or -1 if an error occurred.
+
+ -- Function: int gmp_sprintf (char *BUF, const char *FMT, ...)
+ -- Function: int gmp_vsprintf (char *BUF, const char *FMT, va_list AP)
+     Form a null-terminated string in BUF.  Return the number of
+     characters written, excluding the terminating null.
+
+     No overlap is permitted between the space at BUF and the string
+     FMT.
+
+     These functions are not recommended, since there's no protection
+     against exceeding the space available at BUF.
+
+ -- Function: int gmp_snprintf (char *BUF, size_t SIZE, const char *FMT,
+          ...)
+ -- Function: int gmp_vsnprintf (char *BUF, size_t SIZE, const char
+          *FMT, va_list AP)
+     Form a null-terminated string in BUF.  No more than SIZE bytes will
+     be written.  To get the full output, SIZE must be enough for the
+     string and null-terminator.
+
+     The return value is the total number of characters which ought to
+     have been produced, excluding the terminating null.  If RETVAL >=
+     SIZE then the actual output has been truncated to the first SIZE-1
+     characters, and a null appended.
+
+     No overlap is permitted between the region {BUF,SIZE} and the FMT
+     string.
+
+     Notice the return value is in ISO C99 'snprintf' style.  This is so
+     even if the C library 'vsnprintf' is the older GLIBC 2.0.x style.
+
+ -- Function: int gmp_asprintf (char **PP, const char *FMT, ...)
+ -- Function: int gmp_vasprintf (char **PP, const char *FMT, va_list AP)
+     Form a null-terminated string in a block of memory obtained from
+     the current memory allocation function (*note Custom Allocation::).
+     The block will be the size of the string and null-terminator.  The
+     address of the block in stored to *PP.  The return value is the
+     number of characters produced, excluding the null-terminator.
+
+     Unlike the C library 'asprintf', 'gmp_asprintf' doesn't return -1
+     if there's no more memory available, it lets the current allocation
+     function handle that.
+
+ -- Function: int gmp_obstack_printf (struct obstack *OB, const char
+          *FMT, ...)
+ -- Function: int gmp_obstack_vprintf (struct obstack *OB, const char
+          *FMT, va_list AP)
+     Append to the current object in OB.  The return value is the number
+     of characters written.  A null-terminator is not written.
+
+     FMT cannot be within the current object in OB, since that object
+     might move as it grows.
+
+     These functions are available only when the C library provides the
+     obstack feature, which probably means only on GNU systems, see
+     *note Obstacks: (libc)Obstacks.

+
+10.3 C++ Formatted Output
+=========================
+
+The following functions are provided in 'libgmpxx' (*note Headers and
+Libraries::), which is built if C++ support is enabled (*note Build
+Options::).  Prototypes are available from '<gmp.h>'.
+
+ -- Function: ostream& operator<< (ostream& STREAM, const mpz_t OP)
+     Print OP to STREAM, using its 'ios' formatting settings.
+     'ios::width' is reset to 0 after output, the same as the standard
+     'ostream operator<<' routines do.
+
+     In hex or octal, OP is printed as a signed number, the same as for
+     decimal.  This is unlike the standard 'operator<<' routines on
+     'int' etc, which instead give twos complement.
+
+ -- Function: ostream& operator<< (ostream& STREAM, const mpq_t OP)
+     Print OP to STREAM, using its 'ios' formatting settings.
+     'ios::width' is reset to 0 after output, the same as the standard
+     'ostream operator<<' routines do.
+
+     Output will be a fraction like '5/9', or if the denominator is 1
+     then just a plain integer like '123'.
+
+     In hex or octal, OP is printed as a signed value, the same as for
+     decimal.  If 'ios::showbase' is set then a base indicator is shown
+     on both the numerator and denominator (if the denominator is
+     required).
+
+ -- Function: ostream& operator<< (ostream& STREAM, const mpf_t OP)
+     Print OP to STREAM, using its 'ios' formatting settings.
+     'ios::width' is reset to 0 after output, the same as the standard
+     'ostream operator<<' routines do.
+
+     The decimal point follows the standard library float 'operator<<',
+     which on recent systems means the 'std::locale' imbued on STREAM.
+
+     Hex and octal are supported, unlike the standard 'operator<<' on
+     'double'.  The mantissa will be in hex or octal, the exponent will
+     be in decimal.  For hex the exponent delimiter is an '@'.  This is
+     as per 'mpf_out_str'.
+
+     'ios::showbase' is supported, and will put a base on the mantissa,
+     for example hex '0x1.8' or '0x0.8', or octal '01.4' or '00.4'.
+     This last form is slightly strange, but at least differentiates
+     itself from decimal.
+
+   These operators mean that GMP types can be printed in the usual C++
+way, for example,
+
+     mpz_t  z;
+     int    n;
+     ...
+     cout << "iteration " << n << " value " << z << "\n";
+
+   But note that 'ostream' output (and 'istream' input, *note C++
+Formatted Input::) is the only overloading available for the GMP types
+and that for instance using '+' with an 'mpz_t' will have unpredictable
+results.  For classes with overloading, see *note C++ Class Interface::.

+'scanf' (*note Formatted Input: (libc)Formatted Input.).  A format

+
+   GMP adds types 'Z', 'Q' and 'F' for 'mpz_t', 'mpq_t' and 'mpf_t'
+respectively.  'Z' and 'Q' behave like integers.  'Q' will read a '/'
+and a denominator, if present.  'F' behaves like a float.
+
+   GMP variables don't require an '&' when passed to 'gmp_scanf', since
+they're already "call-by-reference".  For example,
+
+     /* to read say "a(5) = 1234" */
+     int   n;
+     mpz_t z;
+     gmp_scanf ("a(%d) = %Zd\n", &n, z);

+

+
+   'e', 'E', 'f', 'g' and 'G' are identical, they all read either fixed
+point or scientific format, and either upper or lower case 'e' for the
+exponent in scientific format.
+
+   C99 style hex float format ('printf %a', *note Formatted Output
+Strings::) is always accepted for 'mpf_t', but for the standard float
+types it will depend on the C library.
+
+   'x' and 'X' are identical, both accept both upper and lower case
+hexadecimal.
+
+   'o', 'u', 'x' and 'X' all read positive or negative values.  For the
+standard C types these are described as "unsigned" conversions, but that
+merely affects certain overflow handling, negatives are still allowed
+(per 'strtoul', *note Parsing of Integers: (libc)Parsing of Integers.).
+For GMP types there are no overflows, so 'd' and 'u' are identical.
+
+   'Q' type reads the numerator and (optional) denominator as given.  If
+the value might not be in canonical form then 'mpq_canonicalize' must be
+called before using it in any calculations (*note Rational Number
+Functions::).
+
+   'Qi' will read a base specification separately for the numerator and
+denominator.  For example '0x10/11' would be 16/11, whereas '0x10/0x11'
+would be 16/17.
+
+   'n' can be used with any of the types above, even the GMP types.  '*'
+to suppress assignment is allowed, though in that case it would do
+nothing at all.
+
+   Other conversions or types that might be accepted by the C library
+'scanf' cannot be used through 'gmp_scanf'.
+
+   Whitespace is read and discarded before a field, except for 'c' and

+
+   For float conversions, the decimal point character (or string)
+expected is taken from the current locale settings on systems which
+provide 'localeconv' (*note Locales and Internationalization:

+
+11.2 Formatted Input Functions
+==============================
+
+Each of the following functions is similar to the corresponding C
+library function.  The plain 'scanf' forms take a variable argument
+list.  The 'vscanf' forms take an argument pointer, see *note Variadic
+Functions: (libc)Variadic Functions, or 'man 3 va_start'.
+
+   It should be emphasised that if a format string is invalid, or the
+arguments don't match what the format specifies, then the behaviour of
+any of these functions will be unpredictable.  GCC format string
+checking is not available, since it doesn't recognise the GMP
+extensions.
+
+   No overlap is permitted between the FMT string and any of the results
+produced.
+
+ -- Function: int gmp_scanf (const char *FMT, ...)
+ -- Function: int gmp_vscanf (const char *FMT, va_list AP)
+     Read from the standard input 'stdin'.
+
+ -- Function: int gmp_fscanf (FILE *FP, const char *FMT, ...)
+ -- Function: int gmp_vfscanf (FILE *FP, const char *FMT, va_list AP)
+     Read from the stream FP.
+
+ -- Function: int gmp_sscanf (const char *S, const char *FMT, ...)
+ -- Function: int gmp_vsscanf (const char *S, const char *FMT, va_list
+          AP)
+     Read from a null-terminated string S.
+
+   The return value from each of these functions is the same as the
+standard C99 'scanf', namely the number of fields successfully parsed
+and stored.  '%n' fields and fields read but suppressed by '*' don't
+count towards the return value.
+
+   If end of input (or a file error) is reached before a character for a
+field or a literal, and if no previous non-suppressed fields have
+matched, then the return value is 'EOF' instead of 0.  A whitespace
+character in the format string is only an optional match and doesn't
+induce an 'EOF' in this fashion.  Leading whitespace read and discarded
+for a field don't count as characters for that field.
+
+   For the GMP types, input parsing follows C99 rules, namely one
+character of lookahead is used and characters are read while they
+continue to meet the format requirements.  If this doesn't provide a
+complete number then the function terminates, with that field not stored
+nor counted towards the return value.  For instance with 'mpf_t' an
+input '1.23e-XYZ' would be read up to the 'X' and that character pushed
+back since it's not a digit.  The string '1.23e-' would then be
+considered invalid since an 'e' must be followed by at least one digit.
+
+   For the standard C types, in the current implementation GMP calls the
+C library 'scanf' functions, which might have looser rules about what
+constitutes a valid input.
+
+   Note that 'gmp_sscanf' is the same as 'gmp_fscanf' and only does one
+character of lookahead when parsing.  Although clearly it could look at
+its entire input, it is deliberately made identical to 'gmp_fscanf', the

+11.3 C++ Formatted Input
+========================
+
+The following functions are provided in 'libgmpxx' (*note Headers and
+Libraries::), which is built only if C++ support is enabled (*note Build
+Options::).  Prototypes are available from '<gmp.h>'.
+
+ -- Function: istream& operator>> (istream& STREAM, mpz_t ROP)
+     Read ROP from STREAM, using its 'ios' formatting settings.
+
+ -- Function: istream& operator>> (istream& STREAM, mpq_t ROP)
+     An integer like '123' will be read, or a fraction like '5/9'.  No
+     whitespace is allowed around the '/'.  If the fraction is not in
+     canonical form then 'mpq_canonicalize' must be called (*note
+     Rational Number Functions::) before operating on it.
+
+     As per integer input, an '0' or '0x' base indicator is read when
+     none of 'ios::dec', 'ios::oct' or 'ios::hex' are set.  This is done
+     separately for numerator and denominator, so that for instance
+     '0x10/11' is 16/11 and '0x10/0x11' is 16/17.
+
+ -- Function: istream& operator>> (istream& STREAM, mpf_t ROP)
+     Read ROP from STREAM, using its 'ios' formatting settings.
+
+     Hex or octal floats are not supported, but might be in the future,
+     or perhaps it's best to accept only what the standard float
+     'operator>>' does.
+
+   Note that digit grouping specified by the 'istream' locale is
+currently not accepted.  Perhaps this will change in the future.
+
+
+   These operators mean that GMP types can be read in the usual C++ way,
+for example,
+
+     mpz_t  z;
+     ...
+     cin >> z;
+
+   But note that 'istream' input (and 'ostream' output, *note C++
+Formatted Output::) is the only overloading available for the GMP types
+and that for instance using '+' with an 'mpz_t' will have unpredictable
+results.  For classes with overloading, see *note C++ Class Interface::.

+12 C++ Class Interface
+**********************
+
+This chapter describes the C++ class based interface to GMP.
+
+   All GMP C language types and functions can be used in C++ programs,
+since 'gmp.h' has 'extern "C"' qualifiers, but the class interface
+offers overloaded functions and operators which may be more convenient.
+
+   Due to the implementation of this interface, a reasonably recent C++
+compiler is required, one supporting namespaces, partial specialization
+of templates and member templates.
+
+   *Everything described in this chapter is to be considered preliminary
+and might be subject to incompatible changes if some unforeseen
+difficulty reveals itself.*

+
+12.1 C++ Interface General
+==========================
+
+All the C++ classes and functions are available with
+
+     #include <gmpxx.h>
+
+   Programs should be linked with the 'libgmpxx' and 'libgmp' libraries.
+For example,
+
+     g++ mycxxprog.cc -lgmpxx -lgmp
+
+The classes defined are
+
+ -- Class: mpz_class
+ -- Class: mpq_class
+ -- Class: mpf_class
+
+   The standard operators and various standard functions are overloaded
+to allow arithmetic with these classes.  For example,
+
+     int
+     main (void)
+     {
+       mpz_class a, b, c;
+
+       a = 1234;
+       b = "-5678";
+       c = a+b;
+       cout << "sum is " << c << "\n";
+       cout << "absolute value is " << abs(c) << "\n";
+
+       return 0;
+     }
+
+   An important feature of the implementation is that an expression like
+'a=b+c' results in a single call to the corresponding 'mpz_add', without
+using a temporary for the 'b+c' part.  Expressions which by their nature
+imply intermediate values, like 'a=b*c+d*e', still use temporaries
+though.
+
+   The classes can be freely intermixed in expressions, as can the
+classes and the standard types 'long', 'unsigned long' and 'double'.
+Smaller types like 'int' or 'float' can also be intermixed, since C++
+will promote them.
+
+   Note that 'bool' is not accepted directly, but must be explicitly
+cast to an 'int' first.  This is because C++ will automatically convert
+any pointer to a 'bool', so if GMP accepted 'bool' it would make all
+sorts of invalid class and pointer combinations compile but almost
+certainly not do anything sensible.
+
+   Conversions back from the classes to standard C++ types aren't done
+automatically, instead member functions like 'get_si' are provided (see
+the following sections for details).
+
+   Also there are no automatic conversions from the classes to the
+corresponding GMP C types, instead a reference to the underlying C
+object can be obtained with the following functions,
+
+ -- Function: mpz_t mpz_class::get_mpz_t ()
+ -- Function: mpq_t mpq_class::get_mpq_t ()
+ -- Function: mpf_t mpf_class::get_mpf_t ()
+
+   These can be used to call a C function which doesn't have a C++ class
+interface.  For example to set 'a' to the GCD of 'b' and 'c',
+
+     mpz_class a, b, c;
+     ...
+     mpz_gcd (a.get_mpz_t(), b.get_mpz_t(), c.get_mpz_t());
+
+   In the other direction, a class can be initialized from the
+corresponding GMP C type, or assigned to if an explicit constructor is
+used.  In both cases this makes a copy of the value, it doesn't create
+any sort of association.  For example,
+
+     mpz_t z;
+     // ... init and calculate z ...
+     mpz_class x(z);
+     mpz_class y;
+     y = mpz_class (z);
+
+   There are no namespace setups in 'gmpxx.h', all types and functions
+are simply put into the global namespace.  This is what 'gmp.h' has done
+in the past, and continues to do for compatibility.  The extras provided
+by 'gmpxx.h' follow GMP naming conventions and are unlikely to clash
+with anything.

+
+12.2 C++ Interface Integers
+===========================
+
+ -- Function: mpz_class::mpz_class (type N)
+     Construct an 'mpz_class'.  All the standard C++ types may be used,
+     except 'long long' and 'long double', and all the GMP C++ classes
+     can be used, although conversions from 'mpq_class' and 'mpf_class'
+     are 'explicit'.  Any necessary conversion follows the corresponding
+     C function, for example 'double' follows 'mpz_set_d' (*note
+     Assigning Integers::).
+
+ -- Function: explicit mpz_class::mpz_class (const mpz_t Z)
+     Construct an 'mpz_class' from an 'mpz_t'.  The value in Z is copied
+     into the new 'mpz_class', there won't be any permanent association
+     between it and Z.
+
+ -- Function: explicit mpz_class::mpz_class (const char *S, int BASE =
+          0)
+ -- Function: explicit mpz_class::mpz_class (const string& S, int BASE =
+          0)
+     Construct an 'mpz_class' converted from a string using
+     'mpz_set_str' (*note Assigning Integers::).
+
+     If the string is not a valid integer, an 'std::invalid_argument'
+     exception is thrown.  The same applies to 'operator='.
+
+ -- Function: mpz_class operator"" _mpz (const char *STR)
+     With C++11 compilers, integers can be constructed with the syntax
+     '123_mpz' which is equivalent to 'mpz_class("123")'.
+
+ -- Function: mpz_class operator/ (mpz_class A, mpz_class D)
+ -- Function: mpz_class operator% (mpz_class A, mpz_class D)
+     Divisions involving 'mpz_class' round towards zero, as per the
+     'mpz_tdiv_q' and 'mpz_tdiv_r' functions (*note Integer Division::).
+     This is the same as the C99 '/' and '%' operators.
+
+     The 'mpz_fdiv...' or 'mpz_cdiv...' functions can always be called
+     directly if desired.  For example,
+
+          mpz_class q, a, d;
+          ...
+          mpz_fdiv_q (q.get_mpz_t(), a.get_mpz_t(), d.get_mpz_t());
+
+ -- Function: mpz_class abs (mpz_class OP)
+ -- Function: int cmp (mpz_class OP1, type OP2)
+ -- Function: int cmp (type OP1, mpz_class OP2)
+
+ -- Function: bool mpz_class::fits_sint_p (void)
+ -- Function: bool mpz_class::fits_slong_p (void)
+ -- Function: bool mpz_class::fits_sshort_p (void)
+
+ -- Function: bool mpz_class::fits_uint_p (void)
+ -- Function: bool mpz_class::fits_ulong_p (void)
+ -- Function: bool mpz_class::fits_ushort_p (void)
+
+ -- Function: double mpz_class::get_d (void)
+ -- Function: long mpz_class::get_si (void)
+ -- Function: string mpz_class::get_str (int BASE = 10)
+ -- Function: unsigned long mpz_class::get_ui (void)
+
+ -- Function: int mpz_class::set_str (const char *STR, int BASE)
+ -- Function: int mpz_class::set_str (const string& STR, int BASE)
+ -- Function: int sgn (mpz_class OP)
+ -- Function: mpz_class sqrt (mpz_class OP)
+
+ -- Function: mpz_class gcd (mpz_class OP1, mpz_class OP2)
+ -- Function: mpz_class lcm (mpz_class OP1, mpz_class OP2)
+ -- Function: mpz_class mpz_class::factorial (type OP)
+ -- Function: mpz_class factorial (mpz_class OP)
+ -- Function: mpz_class mpz_class::primorial (type OP)
+ -- Function: mpz_class primorial (mpz_class OP)
+ -- Function: mpz_class mpz_class::fibonacci (type OP)
+ -- Function: mpz_class fibonacci (mpz_class OP)
+
+ -- Function: void mpz_class::swap (mpz_class& OP)
+ -- Function: void swap (mpz_class& OP1, mpz_class& OP2)
+     These functions provide a C++ class interface to the corresponding
+     GMP C routines.  Calling 'factorial' or 'primorial' on a negative
+     number is undefined.
+
+     'cmp' can be used with any of the classes or the standard C++
+     types, except 'long long' and 'long double'.
+
+
+   Overloaded operators for combinations of 'mpz_class' and 'double' are
+provided for completeness, but it should be noted that if the given
+'double' is not an integer then the way any rounding is done is
+currently unspecified.  The rounding might take place at the start, in
+the middle, or at the end of the operation, and it might change in the
+future.
+
+   Conversions between 'mpz_class' and 'double', however, are defined to
+follow the corresponding C functions 'mpz_get_d' and 'mpz_set_d'.  And
+comparisons are always made exactly, as per 'mpz_cmp_d'.

+
+12.3 C++ Interface Rationals
+============================
+
+In all the following constructors, if a fraction is given then it should
+be in canonical form, or if not then 'mpq_class::canonicalize' called.
+
+ -- Function: mpq_class::mpq_class (type OP)
+ -- Function: mpq_class::mpq_class (integer NUM, integer DEN)
+     Construct an 'mpq_class'.  The initial value can be a single value
+     of any type (conversion from 'mpf_class' is 'explicit'), or a pair
+     of integers ('mpz_class' or standard C++ integer types)
+     representing a fraction, except that 'long long' and 'long double'
+     are not supported.  For example,
+
+          mpq_class q (99);
+          mpq_class q (1.75);
+          mpq_class q (1, 3);
+
+ -- Function: explicit mpq_class::mpq_class (const mpq_t Q)
+     Construct an 'mpq_class' from an 'mpq_t'.  The value in Q is copied
+     into the new 'mpq_class', there won't be any permanent association
+     between it and Q.
+
+ -- Function: explicit mpq_class::mpq_class (const char *S, int BASE =
+          0)
+ -- Function: explicit mpq_class::mpq_class (const string& S, int BASE =
+          0)
+     Construct an 'mpq_class' converted from a string using
+     'mpq_set_str' (*note Initializing Rationals::).
+
+     If the string is not a valid rational, an 'std::invalid_argument'
+     exception is thrown.  The same applies to 'operator='.
+
+ -- Function: mpq_class operator"" _mpq (const char *STR)
+     With C++11 compilers, integral rationals can be constructed with
+     the syntax '123_mpq' which is equivalent to 'mpq_class(123_mpz)'.
+     Other rationals can be built as '-1_mpq/2' or '0xb_mpq/123456_mpz'.
+
+ -- Function: void mpq_class::canonicalize ()
+     Put an 'mpq_class' into canonical form, as per *note Rational
+     Number Functions::.  All arithmetic operators require their
+     operands in canonical form, and will return results in canonical
+     form.
+
+ -- Function: mpq_class abs (mpq_class OP)
+ -- Function: int cmp (mpq_class OP1, type OP2)
+ -- Function: int cmp (type OP1, mpq_class OP2)
+
+ -- Function: double mpq_class::get_d (void)
+ -- Function: string mpq_class::get_str (int BASE = 10)
+
+ -- Function: int mpq_class::set_str (const char *STR, int BASE)
+ -- Function: int mpq_class::set_str (const string& STR, int BASE)
+ -- Function: int sgn (mpq_class OP)
+
+ -- Function: void mpq_class::swap (mpq_class& OP)
+ -- Function: void swap (mpq_class& OP1, mpq_class& OP2)
+     These functions provide a C++ class interface to the corresponding
+     GMP C routines.
+
+     'cmp' can be used with any of the classes or the standard C++
+     types, except 'long long' and 'long double'.
+
+ -- Function: mpz_class& mpq_class::get_num ()
+ -- Function: mpz_class& mpq_class::get_den ()
+     Get a reference to an 'mpz_class' which is the numerator or
+     denominator of an 'mpq_class'.  This can be used both for read and
+     write access.  If the object returned is modified, it modifies the
+     original 'mpq_class'.
+
+     If direct manipulation might produce a non-canonical value, then
+     'mpq_class::canonicalize' must be called before further operations.
+
+ -- Function: mpz_t mpq_class::get_num_mpz_t ()
+ -- Function: mpz_t mpq_class::get_den_mpz_t ()
+     Get a reference to the underlying 'mpz_t' numerator or denominator
+     of an 'mpq_class'.  This can be passed to C functions expecting an
+     'mpz_t'.  Any modifications made to the 'mpz_t' will modify the
+     original 'mpq_class'.
+
+     If direct manipulation might produce a non-canonical value, then
+     'mpq_class::canonicalize' must be called before further operations.
+
+ -- Function: istream& operator>> (istream& STREAM, mpq_class& ROP);
+     Read ROP from STREAM, using its 'ios' formatting settings, the same
+     as 'mpq_t operator>>' (*note C++ Formatted Input::).
+
+     If the ROP read might not be in canonical form then
+     'mpq_class::canonicalize' must be called.

+12.4 C++ Interface Floats
+=========================
+
+When an expression requires the use of temporary intermediate
+'mpf_class' values, like 'f=g*h+x*y', those temporaries will have the
+same precision as the destination 'f'.  Explicit constructors can be
+used if this doesn't suit.
+
+ -- Function: mpf_class::mpf_class (type OP)
+ -- Function: mpf_class::mpf_class (type OP, mp_bitcnt_t PREC)
+     Construct an 'mpf_class'.  Any standard C++ type can be used,
+     except 'long long' and 'long double', and any of the GMP C++
+     classes can be used.
+
+     If PREC is given, the initial precision is that value, in bits.  If
+     PREC is not given, then the initial precision is determined by the
+     type of OP given.  An 'mpz_class', 'mpq_class', or C++ builtin type
+     will give the default 'mpf' precision (*note Initializing
+     Floats::).  An 'mpf_class' or expression will give the precision of
+     that value.  The precision of a binary expression is the higher of
+     the two operands.
+
+          mpf_class f(1.5);        // default precision
+          mpf_class f(1.5, 500);   // 500 bits (at least)
+          mpf_class f(x);          // precision of x
+          mpf_class f(abs(x));     // precision of x
+          mpf_class f(-g, 1000);   // 1000 bits (at least)
+          mpf_class f(x+y);        // greater of precisions of x and y
+
+ -- Function: explicit mpf_class::mpf_class (const mpf_t F)
+ -- Function: mpf_class::mpf_class (const mpf_t F, mp_bitcnt_t PREC)
+     Construct an 'mpf_class' from an 'mpf_t'.  The value in F is copied
+     into the new 'mpf_class', there won't be any permanent association
+     between it and F.
+
+     If PREC is given, the initial precision is that value, in bits.  If
+     PREC is not given, then the initial precision is that of F.
+
+ -- Function: explicit mpf_class::mpf_class (const char *S)
+ -- Function: mpf_class::mpf_class (const char *S, mp_bitcnt_t PREC, int
+          BASE = 0)
+ -- Function: explicit mpf_class::mpf_class (const string& S)
+ -- Function: mpf_class::mpf_class (const string& S, mp_bitcnt_t PREC,
+          int BASE = 0)
+     Construct an 'mpf_class' converted from a string using
+     'mpf_set_str' (*note Assigning Floats::).  If PREC is given, the
+     initial precision is that value, in bits.  If not, the default
+     'mpf' precision (*note Initializing Floats::) is used.
+
+     If the string is not a valid float, an 'std::invalid_argument'
+     exception is thrown.  The same applies to 'operator='.
+
+ -- Function: mpf_class operator"" _mpf (const char *STR)
+     With C++11 compilers, floats can be constructed with the syntax
+     '1.23e-1_mpf' which is equivalent to 'mpf_class("1.23e-1")'.
+
+ -- Function: mpf_class& mpf_class::operator= (type OP)
+     Convert and store the given OP value to an 'mpf_class' object.  The
+     same types are accepted as for the constructors above.
+
+     Note that 'operator=' only stores a new value, it doesn't copy or
+     change the precision of the destination, instead the value is
+     truncated if necessary.  This is the same as 'mpf_set' etc.  Note
+     in particular this means for 'mpf_class' a copy constructor is not
+     the same as a default constructor plus assignment.
+
+          mpf_class x (y);   // x created with precision of y
+
+          mpf_class x;       // x created with default precision
+          x = y;             // value truncated to that precision
+
+     Applications using templated code may need to be careful about the
+     assumptions the code makes in this area, when working with
+     'mpf_class' values of various different or non-default precisions.
+     For instance implementations of the standard 'complex' template
+     have been seen in both styles above, though of course 'complex' is
+     normally only actually specified for use with the builtin float
+     types.

+
+     'cmp' can be used with any of the classes or the standard C++

+     Get or set the current precision of an 'mpf_class'.
+
+     The restrictions described for 'mpf_set_prec_raw' (*note
+     Initializing Floats::) apply to 'mpf_class::set_prec_raw'.  Note in
+     particular that the 'mpf_class' must be restored to it's allocated

+=================================
+
+ -- Class: gmp_randclass
+     The C++ class interface to the GMP random number functions uses

+     as per 'gmp_randstate_t'.
+
+ -- Function: gmp_randclass::gmp_randclass (void (*RANDINIT)
+          (gmp_randstate_t, ...), ...)
+     Construct a 'gmp_randclass', using a call to the given RANDINIT
+     function (*note Random State Initialization::).  The arguments
+     expected are the same as RANDINIT, but with 'mpz_class' instead of
+     'mpz_t'.  For example,
+

+
+     'gmp_randinit_lc_2exp_size' will fail if the size requested is too

+12.6 C++ Interface Limitations
+==============================
+
+'mpq_class' and Templated Reading
+     A generic piece of template code probably won't know that
+     'mpq_class' requires a 'canonicalize' call if inputs read with
+     'operator>>' might be non-canonical.  This can lead to incorrect
+     results.
+
+     'operator>>' behaves as it does for reasons of efficiency.  A
+     canonicalize can be quite time consuming on large operands, and is
+     best avoided if it's not necessary.
+
+     But this potential difficulty reduces the usefulness of
+     'mpq_class'.  Perhaps a mechanism to tell 'operator>>' what to do
+     will be adopted in the future, maybe a preprocessor define, a
+     global flag, or an 'ios' flag pressed into service.  Or maybe, at
+     the risk of inconsistency, the 'mpq_class' 'operator>>' could
+     canonicalize and leave 'mpq_t' 'operator>>' not doing so, for use
+     on those occasions when that's acceptable.  Send feedback or
+     alternate ideas to <gmp-bugs@gmplib.org>.
+
+Subclassing
+     Subclassing the GMP C++ classes works, but is not currently
+     recommended.
+
+     Expressions involving subclasses resolve correctly (or seem to),
+     but in normal C++ fashion the subclass doesn't inherit constructors
+     and assignments.  There's many of those in the GMP classes, and a
+     good way to reestablish them in a subclass is not yet provided.
+
+Templated Expressions
+     A subtle difficulty exists when using expressions together with
+     application-defined template functions.  Consider the following,
+     with 'T' intended to be some numeric type,
+
+          template <class T>
+          T fun (const T &, const T &);
+
+     When used with, say, plain 'mpz_class' variables, it works fine:
+     'T' is resolved as 'mpz_class'.
+
+          mpz_class f(1), g(2);
+          fun (f, g);    // Good
+
+     But when one of the arguments is an expression, it doesn't work.
+
+          mpz_class f(1), g(2), h(3);
+          fun (f, g+h);  // Bad
+
+     This is because 'g+h' ends up being a certain expression template
+     type internal to 'gmpxx.h', which the C++ template resolution rules
+     are unable to automatically convert to 'mpz_class'.  The workaround
+     is simply to add an explicit cast.
+
+          mpz_class f(1), g(2), h(3);
+          fun (f, mpz_class(g+h));  // Good
+
+     Similarly, within 'fun' it may be necessary to cast an expression
+     to type 'T' when calling a templated 'fun2'.
+
+          template <class T>
+          void fun (T f, T g)
+          {
+            fun2 (f, f+g);     // Bad
+          }
+
+          template <class T>
+          void fun (T f, T g)
+          {
+            fun2 (f, T(f+g));  // Good
+          }
+
+C++11
+     C++11 provides several new ways in which types can be inferred:
+     'auto', 'decltype', etc.  While they can be very convenient, they
+     don't mix well with expression templates.  In this example, the
+     addition is performed twice, as if we had defined 'sum' as a macro.
+
+          mpz_class z = 33;
+          auto sum = z + z;
+          mpz_class prod = sum * sum;
+
+     This other example may crash, though some compilers might make it
+     look like it is working, because the expression 'z+z' goes out of
+     scope before it is evaluated.
+
+          mpz_class z = 33;
+          auto sum = z + z + z;
+          mpz_class prod = sum * 2;
+
+     It is thus strongly recommended to avoid 'auto' anywhere a GMP C++
+     expression may appear.

+
+13 Custom Allocation
+********************
+
+By default GMP uses 'malloc', 'realloc' and 'free' for memory
+allocation, and if they fail GMP prints a message to the standard error
+output and terminates the program.
+
+   Alternate functions can be specified, to allocate memory in a
+different way or to have a different error action on running out of
+memory.
+
+ -- Function: void mp_set_memory_functions (
+          void *(*ALLOC_FUNC_PTR) (size_t),
+          void *(*REALLOC_FUNC_PTR) (void *, size_t, size_t),
+          void (*FREE_FUNC_PTR) (void *, size_t))
+     Replace the current allocation functions from the arguments.  If an
+     argument is 'NULL', the corresponding default function is used.
+
+     These functions will be used for all memory allocation done by GMP,
+     apart from temporary space from 'alloca' if that function is
+     available and GMP is configured to use it (*note Build Options::).
+
+     *Be sure to call 'mp_set_memory_functions' only when there are no
+     active GMP objects allocated using the previous memory functions!
+     Usually that means calling it before any other GMP function.*
+
+   The functions supplied should fit the following declarations:
+
+ -- Function: void * allocate_function (size_t ALLOC_SIZE)
+     Return a pointer to newly allocated space with at least ALLOC_SIZE
+     bytes.
+
+ -- Function: void * reallocate_function (void *PTR, size_t OLD_SIZE,
+          size_t NEW_SIZE)
+     Resize a previously allocated block PTR of OLD_SIZE bytes to be
+     NEW_SIZE bytes.
+
+     The block may be moved if necessary or if desired, and in that case
+     the smaller of OLD_SIZE and NEW_SIZE bytes must be copied to the
+     new location.  The return value is a pointer to the resized block,
+     that being the new location if moved or just PTR if not.
+
+     PTR is never 'NULL', it's always a previously allocated block.
+     NEW_SIZE may be bigger or smaller than OLD_SIZE.
+
+ -- Function: void free_function (void *PTR, size_t SIZE)
+     De-allocate the space pointed to by PTR.
+
+     PTR is never 'NULL', it's always a previously allocated block of
+     SIZE bytes.
+
+   A "byte" here means the unit used by the 'sizeof' operator.
+
+   The REALLOCATE_FUNCTION parameter OLD_SIZE and the FREE_FUNCTION
+parameter SIZE are passed for convenience, but of course they can be
+ignored if not needed by an implementation.  The default functions using
+'malloc' and friends for instance don't use them.
+
+   No error return is allowed from any of these functions, if they
+return then they must have performed the specified operation.  In
+particular note that ALLOCATE_FUNCTION or REALLOCATE_FUNCTION mustn't
+return 'NULL'.
+
+   Getting a different fatal error action is a good use for custom
+allocation functions, for example giving a graphical dialog rather than
+the default print to 'stderr'.  How much is possible when genuinely out
+of memory is another question though.
+
+   There's currently no defined way for the allocation functions to
+recover from an error such as out of memory, they must terminate program
+execution.  A 'longjmp' or throwing a C++ exception will have undefined
+results.  This may change in the future.
+
+   GMP may use allocated blocks to hold pointers to other allocated
+blocks.  This will limit the assumptions a conservative garbage
+collection scheme can make.
+
+   Since the default GMP allocation uses 'malloc' and friends, those
+functions will be linked in even if the first thing a program does is an
+'mp_set_memory_functions'.  It's necessary to change the GMP sources if
+this is a problem.
+
+
+ -- Function: void mp_get_memory_functions (
+          void *(**ALLOC_FUNC_PTR) (size_t),
+          void *(**REALLOC_FUNC_PTR) (void *, size_t, size_t),
+          void (**FREE_FUNC_PTR) (void *, size_t))
+     Get the current allocation functions, storing function pointers to
+     the locations given by the arguments.  If an argument is 'NULL',
+     that function pointer is not stored.
+
+     For example, to get just the current free function,
+
+          void (*freefunc) (void *, size_t);
+
+          mp_get_memory_functions (NULL, NULL, &freefunc);

+15.1.1 Basecase Multiplication
+------------------------------
+
+Basecase NxM multiplication is a straightforward rectangular set of
+cross-products, the same as long multiplication done by hand and for
+that reason sometimes known as the schoolbook or grammar school method.
+This is an O(N*M) algorithm.  See Knuth section 4.3.1 algorithm M (*note
+References::), and the 'mpn/generic/mul_basecase.c' code.
+
+   Assembly implementations of 'mpn_mul_basecase' are essentially the
+same as the generic C code, but have all the usual assembly tricks and
+obscurities introduced for speed.
+
+   A square can be done in roughly half the time of a multiply, by using
+the fact that the cross products above and below the diagonal are the
+same.  A triangle of products below the diagonal is formed, doubled
+(left shift by one bit), and then the products on the diagonal added.
+This can be seen in 'mpn/generic/sqr_basecase.c'.  Again the assembly
+implementations take essentially the same approach.

+        +---+---+---+---+---+
+
+   In practice squaring isn't a full 2x faster than multiplying, it's
+usually around 1.5x.  Less than 1.5x probably indicates
+'mpn_sqr_basecase' wants improving on that CPU.
+
+   On some CPUs 'mpn_mul_basecase' can be faster than the generic C
+'mpn_sqr_basecase' on some small sizes.  'SQR_BASECASE_THRESHOLD' is the
+size at which to use 'mpn_sqr_basecase', this will be zero if that
+routine should be used always.

+
+15.1.2 Karatsuba Multiplication
+-------------------------------
+
+The Karatsuba multiplication algorithm is described in Knuth section
+4.3.3 part A, and various other textbooks.  A brief description is given
+here.
+
+   The inputs x and y are treated as each split into two parts of equal
+length (or the most significant part one limb shorter if N is odd).
+
+      high              low
+     +----------+----------+
+     |    x1    |    x0    |
+     +----------+----------+
+
+     +----------+----------+
+     |    y1    |    y0    |
+     +----------+----------+
+
+   Let b be the power of 2 where the split occurs, i.e. if x0 is k limbs
+(y0 the same) then b=2^(k*mp_bits_per_limb).  With that x=x1*b+x0 and
+y=y1*b+y0, and the following holds,
+
+     x*y = (b^2+b)*x1*y1 - b*(x1-x0)*(y1-y0) + (b+1)*x0*y0
+
+   This formula means doing only three multiplies of (N/2)x(N/2) limbs,
+whereas a basecase multiply of NxN limbs is equivalent to four
+multiplies of (N/2)x(N/2).  The factors (b^2+b) etc represent the
+positions where the three products must be added.
+
+      high                              low
+     +--------+--------+ +--------+--------+
+     |      x1*y1      | |      x0*y0      |
+     +--------+--------+ +--------+--------+
+               +--------+--------+
+           add |      x1*y1      |
+               +--------+--------+
+               +--------+--------+
+           add |      x0*y0      |
+               +--------+--------+
+               +--------+--------+
+           sub | (x1-x0)*(y1-y0) |
+               +--------+--------+
+
+   The term (x1-x0)*(y1-y0) is best calculated as an absolute value, and
+the sign used to choose to add or subtract.  Notice the sum
+high(x0*y0)+low(x1*y1) occurs twice, so it's possible to do 5*k limb
+additions, rather than 6*k, but in GMP extra function call overheads
+outweigh the saving.
+
+   Squaring is similar to multiplying, but with x=y the formula reduces
+to an equivalent with three squares,
+
+     x^2 = (b^2+b)*x1^2 - b*(x1-x0)^2 + (b+1)*x0^2
+
+   The final result is accumulated from those three squares the same way
+as for the three multiplies above.  The middle term (x1-x0)^2 is now
+always positive.
+
+   A similar formula for both multiplying and squaring can be
+constructed with a middle term (x1+x0)*(y1+y0).  But those sums can
+exceed k limbs, leading to more carry handling and additions than the
+form above.
+
+   Karatsuba multiplication is asymptotically an O(N^1.585) algorithm,
+the exponent being log(3)/log(2), representing 3 multiplies each 1/2 the
+size of the inputs.  This is a big improvement over the basecase
+multiply at O(N^2) and the advantage soon overcomes the extra additions
+Karatsuba performs.  'MUL_TOOM22_THRESHOLD' can be as little as 10
+limbs.  The 'SQR' threshold is usually about twice the 'MUL'.
+
+   The basecase algorithm will take a time of the form M(N) = a*N^2 +
+b*N + c and the Karatsuba algorithm K(N) = 3*M(N/2) + d*N + e, which
+expands to K(N) = 3/4*a*N^2 + 3/2*b*N + 3*c + d*N + e.  The factor 3/4
+for a means per-crossproduct speedups in the basecase code will increase
+the threshold since they benefit M(N) more than K(N). And conversely the
+3/2 for b means linear style speedups of b will increase the threshold
+since they benefit K(N) more than M(N). The latter can be seen for
+instance when adding an optimized 'mpn_sqr_diagonal' to
+'mpn_sqr_basecase'.  Of course all speedups reduce total time, and in
+that sense the algorithm thresholds are merely of academic interest.

+15.1.3 Toom 3-Way Multiplication
+--------------------------------
+
+The Karatsuba formula is the simplest case of a general approach to
+splitting inputs that leads to both Toom and FFT algorithms.  A
+description of Toom can be found in Knuth section 4.3.3, with an example
+3-way calculation after Theorem A.  The 3-way form used in GMP is
+described here.
+
+   The operands are each considered split into 3 pieces of equal length
+(or the most significant part 1 or 2 limbs shorter than the other two).
+
+      high                         low
+     +----------+----------+----------+
+     |    x2    |    x1    |    x0    |
+     +----------+----------+----------+
+
+     +----------+----------+----------+
+     |    y2    |    y1    |    y0    |
+     +----------+----------+----------+
+
+These parts are treated as the coefficients of two polynomials
+
+     X(t) = x2*t^2 + x1*t + x0
+     Y(t) = y2*t^2 + y1*t + y0
+
+   Let b equal the power of 2 which is the size of the x0, x1, y0 and y1
+pieces, i.e. if they're k limbs each then b=2^(k*mp_bits_per_limb).
+With this x=X(b) and y=Y(b).
+
+   Let a polynomial W(t)=X(t)*Y(t) and suppose its coefficients are
+
+     W(t) = w4*t^4 + w3*t^3 + w2*t^2 + w1*t + w0
+
+   The w[i] are going to be determined, and when they are they'll give
+the final result using w=W(b), since x*y=X(b)*Y(b)=W(b).  The
+coefficients will be roughly b^2 each, and the final W(b) will be an
+addition like,

+                    +--------+-------+
+                    |        w2      |
+                    +--------+-------+
+                            +--------+-------+
+                            |        w1      |
+                            +--------+-------+
+                                     +-------+-------+
+                                     |       w0      |
+                                     +-------+-------+
+
+   The w[i] coefficients could be formed by a simple set of cross
+products, like w4=x2*y2, w3=x2*y1+x1*y2, w2=x2*y0+x1*y1+x0*y2 etc, but
+this would need all nine x[i]*y[j] for i,j=0,1,2, and would be
+equivalent merely to a basecase multiply.  Instead the following
+approach is used.
+
+   X(t) and Y(t) are evaluated and multiplied at 5 points, giving values
+of W(t) at those points.  In GMP the following points are used,
+
+     Point    Value
+     t=0      x0 * y0, which gives w0 immediately
+     t=1      (x2+x1+x0) * (y2+y1+y0)
+     t=-1     (x2-x1+x0) * (y2-y1+y0)
+     t=2      (4*x2+2*x1+x0) * (4*y2+2*y1+y0)
+     t=inf    x2 * y2, which gives w4 immediately
+
+   At t=-1 the values can be negative and that's handled using the
+absolute values and tracking the sign separately.  At t=inf the value is
+actually X(t)*Y(t)/t^4 in the limit as t approaches infinity, but it's
+much easier to think of as simply x2*y2 giving w4 immediately (much like
+x0*y0 at t=0 gives w0 immediately).
+
+   Each of the points substituted into W(t)=w4*t^4+...+w0 gives a linear
+combination of the w[i] coefficients, and the value of those
+combinations has just been calculated.
+
+     W(0)   =                              w0
+     W(1)   =    w4 +   w3 +   w2 +   w1 + w0
+     W(-1)  =    w4 -   w3 +   w2 -   w1 + w0
+     W(2)   = 16*w4 + 8*w3 + 4*w2 + 2*w1 + w0
+     W(inf) =    w4
+
+   This is a set of five equations in five unknowns, and some elementary
+linear algebra quickly isolates each w[i].  This involves adding or
+subtracting one W(t) value from another, and a couple of divisions by
+powers of 2 and one division by 3, the latter using the special
+'mpn_divexact_by3' (*note Exact Division::).
+
+   The conversion of W(t) values to the coefficients is interpolation.
+A polynomial of degree 4 like W(t) is uniquely determined by values
+known at 5 different points.  The points are arbitrary and can be chosen
+to make the linear equations come out with a convenient set of steps for
+quickly isolating the w[i].
+
+   Squaring follows the same procedure as multiplication, but there's
+only one X(t) and it's evaluated at the 5 points, and those values
+squared to give values of W(t).  The interpolation is then identical,
+and in fact the same 'toom_interpolate_5pts' subroutine is used for both
+squaring and multiplying.
+
+   Toom-3 is asymptotically O(N^1.465), the exponent being
+log(5)/log(3), representing 5 recursive multiplies of 1/3 the original
+size each.  This is an improvement over Karatsuba at O(N^1.585), though
+Toom does more work in the evaluation and interpolation and so it only
+realizes its advantage above a certain size.
+
+   Near the crossover between Toom-3 and Karatsuba there's generally a
+range of sizes where the difference between the two is small.
+'MUL_TOOM33_THRESHOLD' is a somewhat arbitrary point in that range and
+successive runs of the tune program can give different values due to
+small variations in measuring.  A graph of time versus size for the two
+shows the effect, see 'tune/README'.
+
+   At the fairly small sizes where the Toom-3 thresholds occur it's
+worth remembering that the asymptotic behaviour for Karatsuba and Toom-3
+can't be expected to make accurate predictions, due of course to the big
+influence of all sorts of overheads, and the fact that only a few
+recursions of each are being performed.  Even at large sizes there's a
+good chance machine dependent effects like cache architecture will mean
+actual performance deviates from what might be predicted.
+
+   The formula given for the Karatsuba algorithm (*note Karatsuba
+Multiplication::) has an equivalent for Toom-3 involving only five
+multiplies, but this would be complicated and unenlightening.
+
+   An alternate view of Toom-3 can be found in Zuras (*note
+References::), using a vector to represent the x and y splits and a
+matrix multiplication for the evaluation and interpolation stages.  The
+matrix inverses are not meant to be actually used, and they have
+elements with values much greater than in fact arise in the
+interpolation steps.  The diagram shown for the 3-way is attractive, but
+again doesn't have to be implemented that way and for example with a bit
+of rearrangement just one division by 6 can be done.

+
+15.1.4 Toom 4-Way Multiplication
+--------------------------------
+
+Karatsuba and Toom-3 split the operands into 2 and 3 coefficients,
+respectively.  Toom-4 analogously splits the operands into 4
+coefficients.  Using the notation from the section on Toom-3
+multiplication, we form two polynomials:
+
+     X(t) = x3*t^3 + x2*t^2 + x1*t + x0
+     Y(t) = y3*t^3 + y2*t^2 + y1*t + y0
+
+   X(t) and Y(t) are evaluated and multiplied at 7 points, giving values
+of W(t) at those points.  In GMP the following points are used,
+
+     Point    Value
+     t=0      x0 * y0, which gives w0 immediately
+     t=1/2    (x3+2*x2+4*x1+8*x0) * (y3+2*y2+4*y1+8*y0)
+     t=-1/2   (-x3+2*x2-4*x1+8*x0) * (-y3+2*y2-4*y1+8*y0)
+     t=1      (x3+x2+x1+x0) * (y3+y2+y1+y0)
+     t=-1     (-x3+x2-x1+x0) * (-y3+y2-y1+y0)
+     t=2      (8*x3+4*x2+2*x1+x0) * (8*y3+4*y2+2*y1+y0)
+     t=inf    x3 * y3, which gives w6 immediately
+
+   The number of additions and subtractions for Toom-4 is much larger
+than for Toom-3.  But several subexpressions occur multiple times, for
+example x2+x0, occurs for both t=1 and t=-1.
+
+   Toom-4 is asymptotically O(N^1.404), the exponent being
+log(7)/log(4), representing 7 recursive multiplies of 1/4 the original
+size each.

+
+15.1.5 Higher degree Toom'n'half
+--------------------------------
+
+The Toom algorithms described above (*note Toom 3-Way Multiplication::,
+*note Toom 4-Way Multiplication::) generalizes to split into an
+arbitrary number of pieces.  In general a split of two equally long
+operands into r pieces leads to evaluations and pointwise
+multiplications done at 2*r-1 points.  To fully exploit symmetries it
+would be better to have a multiple of 4 points, that's why for higher
+degree Toom'n'half is used.
+
+   Toom'n'half means that the existence of one more piece is considered
+for a single operand.  It can be virtual, i.e.  zero, or real, when the
+two operand are not exactly balanced.  By choosing an even r, Toom-r+1/2
+requires 2r points, a multiple of four.
+
+   The quadruplets of points include 0, inf, +1, -1 and +-2^i, +-2^-i .
+Each of them giving shortcuts for the evaluation phase and for some
+steps in the interpolation phase.  Further tricks are used to reduce the
+memory footprint of the whole multiplication algorithm to a memory
+buffer equal in size to the result of the product.
+
+   Current GMP uses both Toom-6'n'half and Toom-8'n'half.

+
+15.1.6 FFT Multiplication
+-------------------------
+
+At large to very large sizes a Fermat style FFT multiplication is used,
+following Schönhage and Strassen (*note References::).  Descriptions of
+FFTs in various forms can be found in many textbooks, for instance Knuth
+section 4.3.3 part C or Lipson chapter IX.  A brief description of the
+form used in GMP is given here.
+
+   The multiplication done is x*y mod 2^N+1, for a given N. A full
+product x*y is obtained by choosing N>=bits(x)+bits(y) and padding x and
+y with high zero limbs.  The modular product is the native form for the
+algorithm, so padding to get a full product is unavoidable.
+
+   The algorithm follows a split, evaluate, pointwise multiply,
+interpolate and combine similar to that described above for Karatsuba
+and Toom-3.  A k parameter controls the split, with an FFT-k splitting
+into 2^k pieces of M=N/2^k bits each.  N must be a multiple of
+(2^k)*mp_bits_per_limb so the split falls on limb boundaries, avoiding
+bit shifts in the split and combine stages.
+
+   The evaluations, pointwise multiplications, and interpolation, are
+all done modulo 2^N'+1 where N' is 2M+k+3 rounded up to a multiple of
+2^k and of 'mp_bits_per_limb'.  The results of interpolation will be the
+following negacyclic convolution of the input pieces, and the choice of
+N' ensures these sums aren't truncated.
+
+                ---
+                \         b
+     w[n] =     /     (-1) * x[i] * y[j]
+                ---
+            i+j==b*2^k+n
+               b=0,1
+
+   The points used for the evaluation are g^i for i=0 to 2^k-1 where
+g=2^(2N'/2^k).  g is a 2^k'th root of unity mod 2^N'+1, which produces
+necessary cancellations at the interpolation stage, and it's also a
+power of 2 so the fast Fourier transforms used for the evaluation and
+interpolation do only shifts, adds and negations.
+
+   The pointwise multiplications are done modulo 2^N'+1 and either
+recurse into a further FFT or use a plain multiplication (Toom-3,
+Karatsuba or basecase), whichever is optimal at the size N'. The
+interpolation is an inverse fast Fourier transform.  The resulting set
+of sums of x[i]*y[j] are added at appropriate offsets to give the final
+result.
+
+   Squaring is the same, but x is the only input so it's one transform
+at the evaluate stage and the pointwise multiplies are squares.  The
+interpolation is the same.
+
+   For a mod 2^N+1 product, an FFT-k is an O(N^(k/(k-1))) algorithm, the
+exponent representing 2^k recursed modular multiplies each 1/2^(k-1) the
+size of the original.  Each successive k is an asymptotic improvement,
+but overheads mean each is only faster at bigger and bigger sizes.  In
+the code, 'MUL_FFT_TABLE' and 'SQR_FFT_TABLE' are the thresholds where
+each k is used.  Each new k effectively swaps some multiplying for some
+shifts, adds and overheads.
+
+   A mod 2^N+1 product can be formed with a normal NxN->2N bit multiply
+plus a subtraction, so an FFT and Toom-3 etc can be compared directly.
+A k=4 FFT at O(N^1.333) can be expected to be the first faster than
+Toom-3 at O(N^1.465).  In practice this is what's found, with
+'MUL_FFT_MODF_THRESHOLD' and 'SQR_FFT_MODF_THRESHOLD' being between 300
+and 1000 limbs, depending on the CPU.  So far it's been found that only
+very large FFTs recurse into pointwise multiplies above these sizes.
+
+   When an FFT is to give a full product, the change of N to 2N doesn't
+alter the theoretical complexity for a given k, but for the purposes of
+considering where an FFT might be first used it can be assumed that the
+FFT is recursing into a normal multiply and that on that basis it's
+doing 2^k recursed multiplies each 1/2^(k-2) the size of the inputs,
+making it O(N^(k/(k-2))).  This would mean k=7 at O(N^1.4) would be the
+first FFT faster than Toom-3.  In practice 'MUL_FFT_THRESHOLD' and
+'SQR_FFT_THRESHOLD' have been found to be in the k=8 range, somewhere
+between 3000 and 10000 limbs.
+
+   The way N is split into 2^k pieces and then 2M+k+3 is rounded up to a
+multiple of 2^k and 'mp_bits_per_limb' means that when
+2^k>=mp\_bits\_per\_limb the effective N is a multiple of 2^(2k-1) bits.
+The +k+3 means some values of N just under such a multiple will be
+rounded to the next.  The complexity calculations above assume that a
+favourable size is used, meaning one which isn't padded through
+rounding, and it's also assumed that the extra +k+3 bits are negligible
+at typical FFT sizes.
+
+   The practical effect of the 2^(2k-1) constraint is to introduce a
+step-effect into measured speeds.  For example k=8 will round N up to a
+multiple of 32768 bits, so for a 32-bit limb there'll be 512 limb groups
+of sizes for which 'mpn_mul_n' runs at the same speed.  Or for k=9
+groups of 2048 limbs, k=10 groups of 8192 limbs, etc.  In practice it's
+been found each k is used at quite small multiples of its size
+constraint and so the step effect is quite noticeable in a time versus
+size graph.
+
+   The threshold determinations currently measure at the mid-points of
+size steps, but this is sub-optimal since at the start of a new step it
+can happen that it's better to go back to the previous k for a while.
+Something more sophisticated for 'MUL_FFT_TABLE' and 'SQR_FFT_TABLE'
+will be needed.

+15.1.7 Other Multiplication
+---------------------------
+
+The Toom algorithms described above (*note Toom 3-Way Multiplication::,
+*note Toom 4-Way Multiplication::) generalizes to split into an
+arbitrary number of pieces, as per Knuth section 4.3.3 algorithm C.
+This is not currently used.  The notes here are merely for interest.
+
+   In general a split into r+1 pieces is made, and evaluations and
+pointwise multiplications done at 2*r+1 points.  A 4-way split does 7
+pointwise multiplies, 5-way does 9, etc.  Asymptotically an (r+1)-way
+algorithm is O(N^(log(2*r+1)/log(r+1))).  Only the pointwise
+multiplications count towards big-O complexity, but the time spent in
+the evaluate and interpolate stages grows with r and has a significant
+practical impact, with the asymptotic advantage of each r realized only
+at bigger and bigger sizes.  The overheads grow as O(N*r), whereas in an
+r=2^k FFT they grow only as O(N*log(r)).
+
+   Knuth algorithm C evaluates at points 0,1,2,...,2*r, but exercise 4
+uses -r,...,0,...,r and the latter saves some small multiplies in the
+evaluate stage (or rather trades them for additions), and has a further
+saving of nearly half the interpolate steps.  The idea is to separate
+odd and even final coefficients and then perform algorithm C steps C7
+and C8 on them separately.  The divisors at step C7 become j^2 and the
+multipliers at C8 become 2*t*j-j^2.
+
+   Splitting odd and even parts through positive and negative points can
+be thought of as using -1 as a square root of unity.  If a 4th root of
+unity was available then a further split and speedup would be possible,
+but no such root exists for plain integers.  Going to complex integers
+with i=sqrt(-1) doesn't help, essentially because in Cartesian form it
+takes three real multiplies to do a complex multiply.  The existence of
+2^k'th roots of unity in a suitable ring or field lets the fast Fourier
+transform keep splitting and get to O(N*log(r)).
+
+   Floating point FFTs use complex numbers approximating Nth roots of
+unity.  Some processors have special support for such FFTs.  But these
+are not used in GMP since it's very difficult to guarantee an exact
+result (to some number of bits).  An occasional difference of 1 in the
+last bit might not matter to a typical signal processing algorithm, but
+is of course of vital importance to GMP.

+15.1.8 Unbalanced Multiplication
+--------------------------------
+
+Multiplication of operands with different sizes, both below
+'MUL_TOOM22_THRESHOLD' are done with plain schoolbook multiplication
+(*note Basecase Multiplication::).
+
+   For really large operands, we invoke FFT directly.
+
+   For operands between these sizes, we use Toom inspired algorithms
+suggested by Alberto Zanoni and Marco Bodrato.  The idea is to split the
+operands into polynomials of different degree.  GMP currently splits the
+smaller operand onto 2 coefficients, i.e., a polynomial of degree 1, but
+the larger operand can be split into 2, 3, or 4 coefficients, i.e., a
+polynomial of degree 1 to 3.

+
+15.2.1 Single Limb Division
+---------------------------
+
+Nx1 division is implemented using repeated 2x1 divisions from high to
+low, either with a hardware divide instruction or a multiplication by
+inverse, whichever is best on a given CPU.
+
+   The multiply by inverse follows "Improved division by invariant
+integers" by Möller and Granlund (*note References::) and is implemented
+as 'udiv_qrnnd_preinv' in 'gmp-impl.h'.  The idea is to have a
+fixed-point approximation to 1/d (see 'invert_limb') and then multiply
+by the high limb (plus one bit) of the dividend to get a quotient q.
+With d normalized (high bit set), q is no more than 1 too small.
+Subtracting q*d from the dividend gives a remainder, and reveals whether
+q or q-1 is correct.
+
+   The result is a division done with two multiplications and four or
+five arithmetic operations.  On CPUs with low latency multipliers this
+can be much faster than a hardware divide, though the cost of
+calculating the inverse at the start may mean it's only better on inputs
+bigger than say 4 or 5 limbs.
+
+   When a divisor must be normalized, either for the generic C
+'__udiv_qrnnd_c' or the multiply by inverse, the division performed is
+actually a*2^k by d*2^k where a is the dividend and k is the power
+necessary to have the high bit of d*2^k set.  The bit shifts for the
+dividend are usually accomplished "on the fly" meaning by extracting the
+appropriate bits at each step.  Done this way the quotient limbs come
+out aligned ready to store.  When only the remainder is wanted, an
+alternative is to take the dividend limbs unshifted and calculate r = a
+mod d*2^k followed by an extra final step r*2^k mod d*2^k.  This can
+help on CPUs with poor bit shifts or few registers.
+
+   The multiply by inverse can be done two limbs at a time.  The
+calculation is basically the same, but the inverse is two limbs and the
+divisor treated as if padded with a low zero limb.  This means more
+work, since the inverse will need a 2x2 multiply, but the four 1x1s to
+do that are independent and can therefore be done partly or wholly in
+parallel.  Likewise for a 2x1 calculating q*d.  The net effect is to
+process two limbs with roughly the same two multiplies worth of latency
+that one limb at a time gives.  This extends to 3 or 4 limbs at a time,
+though the extra work to apply the inverse will almost certainly soon
+reach the limits of multiplier throughput.
+
+   A similar approach in reverse can be taken to process just half a
+limb at a time if the divisor is only a half limb.  In this case the 1x1
+multiply for the inverse effectively becomes two (1/2)x1 for each limb,
+which can be a saving on CPUs with a fast half limb multiply, or in fact
+if the only multiply is a half limb, and especially if it's not
+pipelined.

+
+15.2.2 Basecase Division
+------------------------
+
+Basecase NxM division is like long division done by hand, but in base
+2^mp_bits_per_limb.  See Knuth section 4.3.1 algorithm D, and
+'mpn/generic/sb_divrem_mn.c'.
+
+   Briefly stated, while the dividend remains larger than the divisor, a
+high quotient limb is formed and the Nx1 product q*d subtracted at the
+top end of the dividend.  With a normalized divisor (most significant
+bit set), each quotient limb can be formed with a 2x1 division and a 1x1
+multiplication plus some subtractions.  The 2x1 division is by the high
+limb of the divisor and is done either with a hardware divide or a
+multiply by inverse (the same as in *note Single Limb Division::)
+whichever is faster.  Such a quotient is sometimes one too big,
+requiring an addback of the divisor, but that happens rarely.
+
+   With Q=N-M being the number of quotient limbs, this is an O(Q*M)
+algorithm and will run at a speed similar to a basecase QxM
+multiplication, differing in fact only in the extra multiply and divide
+for each of the Q quotient limbs.

+
+15.2.3 Divide and Conquer Division
+----------------------------------
+
+For divisors larger than 'DC_DIV_QR_THRESHOLD', division is done by
+dividing.  Or to be precise by a recursive divide and conquer algorithm
+based on work by Moenck and Borodin, Jebelean, and Burnikel and Ziegler
+(*note References::).
+
+   The algorithm consists essentially of recognising that a 2NxN
+division can be done with the basecase division algorithm (*note
+Basecase Division::), but using N/2 limbs as a base, not just a single
+limb.  This way the multiplications that arise are (N/2)x(N/2) and can
+take advantage of Karatsuba and higher multiplication algorithms (*note
+Multiplication Algorithms::).  The two "digits" of the quotient are
+formed by recursive Nx(N/2) divisions.
+
+   If the (N/2)x(N/2) multiplies are done with a basecase multiplication
+then the work is about the same as a basecase division, but with more
+function call overheads and with some subtractions separated from the
+multiplies.  These overheads mean that it's only when N/2 is above
+'MUL_TOOM22_THRESHOLD' that divide and conquer is of use.
+
+   'DC_DIV_QR_THRESHOLD' is based on the divisor size N, so it will be
+somewhere above twice 'MUL_TOOM22_THRESHOLD', but how much above depends
+on the CPU.  An optimized 'mpn_mul_basecase' can lower
+'DC_DIV_QR_THRESHOLD' a little by offering a ready-made advantage over
+repeated 'mpn_submul_1' calls.
+
+   Divide and conquer is asymptotically O(M(N)*log(N)) where M(N) is the
+time for an NxN multiplication done with FFTs.  The actual time is a sum
+over multiplications of the recursed sizes, as can be seen near the end
+of section 2.2 of Burnikel and Ziegler.  For example, within the Toom-3
+range, divide and conquer is 2.63*M(N). With higher algorithms the M(N)
+term improves and the multiplier tends to log(N). In practice, at
+moderate to large sizes, a 2NxN division is about 2 to 4 times slower
+than an NxN multiplication.

+15.2.4 Block-Wise Barrett Division
+----------------------------------
+
+For the largest divisions, a block-wise Barrett division algorithm is
+used.  Here, the divisor is inverted to a precision determined by the
+relative size of the dividend and divisor.  Blocks of quotient limbs are
+then generated by multiplying blocks from the dividend by the inverse.
+
+   Our block-wise algorithm computes a smaller inverse than in the plain
+Barrett algorithm.  For a 2n/n division, the inverse will be just
+ceil(n/2) limbs.
+
+
+File: gmp.info,  Node: Exact Division,  Next: Exact Remainder,  Prev: Block-Wise Barrett Division,  Up: Division Algorithms
+
+15.2.5 Exact Division
+---------------------
+
+A so-called exact division is when the dividend is known to be an exact
+multiple of the divisor.  Jebelean's exact division algorithm uses this
+knowledge to make some significant optimizations (*note References::).
+
+   The idea can be illustrated in decimal for example with 368154
+divided by 543.  Because the low digit of the dividend is 4, the low
+digit of the quotient must be 8.  This is arrived at from 4*7 mod 10,
+using the fact 7 is the modular inverse of 3 (the low digit of the
+divisor), since 3*7 == 1 mod 10.  So 8*543=4344 can be subtracted from
+the dividend leaving 363810.  Notice the low digit has become zero.
+
+   The procedure is repeated at the second digit, with the next quotient
+digit 7 (7 == 1*7 mod 10), subtracting 7*543=3801, leaving 325800.  And
+finally at the third digit with quotient digit 6 (8*7 mod 10),
+subtracting 6*543=3258 leaving 0.  So the quotient is 678.
+
+   Notice however that the multiplies and subtractions don't need to
+extend past the low three digits of the dividend, since that's enough to
+determine the three quotient digits.  For the last quotient digit no
+subtraction is needed at all.  On a 2NxN division like this one, only
+about half the work of a normal basecase division is necessary.
+
+   For an NxM exact division producing Q=N-M quotient limbs, the saving
+over a normal basecase division is in two parts.  Firstly, each of the Q
+quotient limbs needs only one multiply, not a 2x1 divide and multiply.
+Secondly, the crossproducts are reduced when Q>M to Q*M-M*(M+1)/2, or
+when Q<=M to Q*(Q-1)/2.  Notice the savings are complementary.  If Q is
+big then many divisions are saved, or if Q is small then the
+crossproducts reduce to a small number.
+
+   The modular inverse used is calculated efficiently by 'binvert_limb'
+in 'gmp-impl.h'.  This does four multiplies for a 32-bit limb, or six
+for a 64-bit limb.  'tune/modlinv.c' has some alternate implementations
+that might suit processors better at bit twiddling than multiplying.
+
+   The sub-quadratic exact division described by Jebelean in "Exact
+Division with Karatsuba Complexity" is not currently implemented.  It
+uses a rearrangement similar to the divide and conquer for normal
+division (*note Divide and Conquer Division::), but operating from low
+to high.  A further possibility not currently implemented is
+"Bidirectional Exact Integer Division" by Krandick and Jebelean which
+forms quotient limbs from both the high and low ends of the dividend,
+and can halve once more the number of crossproducts needed in a 2NxN
+division.
+
+   A special case exact division by 3 exists in 'mpn_divexact_by3',
+supporting Toom-3 multiplication and 'mpq' canonicalizations.  It forms
+quotient digits with a multiply by the modular inverse of 3 (which is
+'0xAA..AAB') and uses two comparisons to determine a borrow for the next
+limb.  The multiplications don't need to be on the dependent chain, as
+long as the effect of the borrows is applied, which can help chips with
+pipelined multipliers.

+@chapter Introduction to GNU MP
+@cindex Introduction
+
+GNU MP is a portable library written in C for arbitrary precision arithmetic
+on integers, rational numbers, and floating-point numbers.  It aims to provide
+the fastest possible arithmetic for all applications that need higher
+precision than is directly supported by the basic C types.
+
+Many applications use just a few hundred bits of precision; but some
+applications may need thousands or even millions of bits.  GMP is designed to
+give good performance for both, by choosing algorithms based on the sizes of
+the operands, and by carefully keeping the overhead at a minimum.
+
+The speed of GMP is achieved by using fullwords as the basic arithmetic type,
+by using sophisticated algorithms, by including carefully optimized assembly
+code for the most common inner loops for many different CPUs, and by a general
+emphasis on speed (as opposed to simplicity or elegance).
+
+There is assembly code for these CPUs:
+@cindex CPU types
+ARM Cortex-A9, Cortex-A15, and generic ARM,
+DEC Alpha 21064, 21164, and 21264,
+AMD K8 and K10 (sold under many brands, e.g. Athlon64, Phenom, Opteron)
+Bulldozer, and Bobcat,
+Intel Pentium, Pentium Pro/II/III, Pentium 4, Core2, Nehalem, Sandy bridge, Haswell, generic x86,
+Intel IA-64,
+Motorola/IBM PowerPC 32 and 64 such as POWER970, POWER5, POWER6, and POWER7,
+MIPS 32-bit and 64-bit,
+SPARC 32-bit ad 64-bit with special support for all UltraSPARC models.
+There is also assembly code for many obsolete CPUs.

+@cindex About this manual
+
+Everyone should read @ref{GMP Basics}.  If you need to install the library
+yourself, then read @ref{Installing GMP}.  If you have a system with multiple
+ABIs, then read @ref{ABI and ISA}, for the compiler options that must be used
+on applications.
+
+The rest of the manual can be used for later reference, although it is
+probably a good idea to glance through it.

+@cindex Building GMP
+
+GMP has an autoconf/automake/libtool based configuration system.  On a
+Unix-like system a basic build can be done with
+
+@example
+./configure
+make
+@end example
+
+@noindent
+Some self-tests can be run with
+
+@example
+make check
+@end example
+
+@noindent
+And you can install (under @file{/usr/local} by default) with
+
+@example
+make install
+@end example
+
+If you experience problems, please report them to @email{gmp-bugs@@gmplib.org}.
+See @ref{Reporting Bugs}, for information on what to include in useful bug
+reports.

+@section Build Options
+@cindex Build options
+
+All the usual autoconf configure options are available, run @samp{./configure
+--help} for a summary.  The file @file{INSTALL.autoconf} has some generic
+installation information too.
+
+@table @asis
+@item Tools
+@cindex Non-Unix systems
+@samp{configure} requires various Unix-like tools.  See @ref{Notes for
+Particular Systems}, for some options on non-Unix systems.
+
+It might be possible to build without the help of @samp{configure}, certainly
+all the code is there, but unfortunately you'll be on your own.
+
+@item Build Directory
+@cindex Build directory
+To compile in a separate build directory, @command{cd} to that directory, and
+prefix the configure command with the path to the GMP source directory.  For
+example
+
+@example
+cd /my/build/dir
+/my/sources/gmp-@value{VERSION}/configure
+@end example
+
+Not all @samp{make} programs have the necessary features (@code{VPATH}) to
+support this.  In particular, SunOS and Slowaris @command{make} have bugs that
+make them unable to build in a separate directory.  Use GNU @command{make}
+instead.
+
+@item @option{--prefix} and @option{--exec-prefix}
+@cindex Prefix
+@cindex Exec prefix
+@cindex Install prefix
+@cindex @code{--prefix}
+@cindex @code{--exec-prefix}
+The @option{--prefix} option can be used in the normal way to direct GMP to
+install under a particular tree.  The default is @samp{/usr/local}.
+
+@option{--exec-prefix} can be used to direct architecture-dependent files like
+@file{libgmp.a} to a different location.  This can be used to share
+architecture-independent parts like the documentation, but separate the
+dependent parts.  Note however that @file{gmp.h} is
+architecture-dependent since it encodes certain aspects of @file{libgmp}, so
+it will be necessary to ensure both @file{$prefix/include} and
+@file{$exec_prefix/include} are available to the compiler.
+
+@item @option{--disable-shared}, @option{--disable-static}
+@cindex @code{--disable-shared}
+@cindex @code{--disable-static}
+By default both shared and static libraries are built (where possible), but
+one or other can be disabled.  Shared libraries result in smaller executables
+and permit code sharing between separate running processes, but on some CPUs
+are slightly slower, having a small cost on each function call.
+
+@item Native Compilation, @option{--build=CPU-VENDOR-OS}
+@cindex Native compilation
+@cindex Build system
+@cindex @code{--build}
+For normal native compilation, the system can be specified with
+@samp{--build}.  By default @samp{./configure} uses the output from running
+@samp{./config.guess}.  On some systems @samp{./config.guess} can determine
+the exact CPU type, on others it will be necessary to give it explicitly.  For
+example,
+
+@example
+./configure --build=ultrasparc-sun-solaris2.7
+@end example
+
+In all cases the @samp{OS} part is important, since it controls how libtool
+generates shared libraries.  Running @samp{./config.guess} is the simplest way
+to see what it should be, if you don't know already.
+
+@item Cross Compilation, @option{--host=CPU-VENDOR-OS}
+@cindex Cross compiling
+@cindex Host system
+@cindex @code{--host}
+When cross-compiling, the system used for compiling is given by @samp{--build}
+and the system where the library will run is given by @samp{--host}.  For
+example when using a FreeBSD Athlon system to build GNU/Linux m68k binaries,
+
+@example
+./configure --build=athlon-pc-freebsd3.5 --host=m68k-mac-linux-gnu
+@end example
+
+Compiler tools are sought first with the host system type as a prefix.  For
+example @command{m68k-mac-linux-gnu-ranlib} is tried, then plain
+@command{ranlib}.  This makes it possible for a set of cross-compiling tools
+to co-exist with native tools.  The prefix is the argument to @samp{--host},
+and this can be an alias, such as @samp{m68k-linux}.  But note that tools
+don't have to be setup this way, it's enough to just have a @env{PATH} with a
+suitable cross-compiling @command{cc} etc.
+
+Compiling for a different CPU in the same family as the build system is a form
+of cross-compilation, though very possibly this would merely be special
+options on a native compiler.  In any case @samp{./configure} avoids depending
+on being able to run code on the build system, which is important when
+creating binaries for a newer CPU since they very possibly won't run on the
+build system.
+
+In all cases the compiler must be able to produce an executable (of whatever
+format) from a standard C @code{main}.  Although only object files will go to
+make up @file{libgmp}, @samp{./configure} uses linking tests for various
+purposes, such as determining what functions are available on the host system.
+
+Currently a warning is given unless an explicit @samp{--build} is used when
+cross-compiling, because it may not be possible to correctly guess the build
+system type if the @env{PATH} has only a cross-compiling @command{cc}.
+
+Note that the @samp{--target} option is not appropriate for GMP@.  It's for use
+when building compiler tools, with @samp{--host} being where they will run,
+and @samp{--target} what they'll produce code for.  Ordinary programs or
+libraries like GMP are only interested in the @samp{--host} part, being where
+they'll run.  (Some past versions of GMP used @samp{--target} incorrectly.)
+
+@item CPU types
+@cindex CPU types
+In general, if you want a library that runs as fast as possible, you should
+configure GMP for the exact CPU type your system uses.  However, this may mean
+the binaries won't run on older members of the family, and might run slower on
+other members, older or newer.  The best idea is always to build GMP for the
+exact machine type you intend to run it on.
+
+The following CPUs have specific support.  See @file{configure.ac} for details
+of what code and compiler options they select.
+
+@itemize @bullet

+CPUs not listed will use generic C code.
+
+@item Generic C Build
+@cindex Generic C
+If some of the assembly code causes problems, or if otherwise desired, the
+generic C code can be selected with the configure @option{--disable-assembly}.
+
+Note that this will run quite slowly, but it should be portable and should at
+least make it possible to get something running if all else fails.
+
+@item Fat binary, @option{--enable-fat}
+@cindex Fat binary
+@cindex @code{--enable-fat}
+Using @option{--enable-fat} selects a ``fat binary'' build on x86, where
+optimized low level subroutines are chosen at runtime according to the CPU
+detected.  This means more code, but gives good performance on all x86 chips.
+(This option might become available for more architectures in the future.)
+
+@item @option{ABI}
+@cindex ABI
+On some systems GMP supports multiple ABIs (application binary interfaces),
+meaning data type sizes and calling conventions.  By default GMP chooses the
+best ABI available, but a particular ABI can be selected.  For example
+
+@example
+./configure --host=mips64-sgi-irix6 ABI=n32
+@end example
+
+See @ref{ABI and ISA}, for the available choices on relevant CPUs, and what
+applications need to do.
+
+@item @option{CC}, @option{CFLAGS}
+@cindex C compiler
+@cindex @code{CC}
+@cindex @code{CFLAGS}
+By default the C compiler used is chosen from among some likely candidates,
+with @command{gcc} normally preferred if it's present.  The usual
+@samp{CC=whatever} can be passed to @samp{./configure} to choose something
+different.
+
+For various systems, default compiler flags are set based on the CPU and
+compiler.  The usual @samp{CFLAGS="-whatever"} can be passed to
+@samp{./configure} to use something different or to set good flags for systems
+GMP doesn't otherwise know.
+
+The @samp{CC} and @samp{CFLAGS} used are printed during @samp{./configure},
+and can be found in each generated @file{Makefile}.  This is the easiest way
+to check the defaults when considering changing or adding something.
+
+Note that when @samp{CC} and @samp{CFLAGS} are specified on a system
+supporting multiple ABIs it's important to give an explicit
+@samp{ABI=whatever}, since GMP can't determine the ABI just from the flags and
+won't be able to select the correct assembly code.
+
+If just @samp{CC} is selected then normal default @samp{CFLAGS} for that
+compiler will be used (if GMP recognises it).  For example @samp{CC=gcc} can
+be used to force the use of GCC, with default flags (and default ABI).
+
+@item @option{CPPFLAGS}
+@cindex @code{CPPFLAGS}
+Any flags like @samp{-D} defines or @samp{-I} includes required by the
+preprocessor should be set in @samp{CPPFLAGS} rather than @samp{CFLAGS}.
+Compiling is done with both @samp{CPPFLAGS} and @samp{CFLAGS}, but
+preprocessing uses just @samp{CPPFLAGS}.  This distinction is because most
+preprocessors won't accept all the flags the compiler does.  Preprocessing is
+done separately in some configure tests.
+
+@item @option{CC_FOR_BUILD}
+@cindex @code{CC_FOR_BUILD}
+Some build-time programs are compiled and run to generate host-specific data
+tables.  @samp{CC_FOR_BUILD} is the compiler used for this.  It doesn't need
+to be in any particular ABI or mode, it merely needs to generate executables
+that can run.  The default is to try the selected @samp{CC} and some likely
+candidates such as @samp{cc} and @samp{gcc}, looking for something that works.
+
+No flags are used with @samp{CC_FOR_BUILD} because a simple invocation like
+@samp{cc foo.c} should be enough.  If some particular options are required
+they can be included as for instance @samp{CC_FOR_BUILD="cc -whatever"}.
+
+@item C++ Support, @option{--enable-cxx}
+@cindex C++ support
+@cindex @code{--enable-cxx}
+C++ support in GMP can be enabled with @samp{--enable-cxx}, in which case a
+C++ compiler will be required.  As a convenience @samp{--enable-cxx=detect}
+can be used to enable C++ support only if a compiler can be found.  The C++
+support consists of a library @file{libgmpxx.la} and header file
+@file{gmpxx.h} (@pxref{Headers and Libraries}).
+
+A separate @file{libgmpxx.la} has been adopted rather than having C++ objects
+within @file{libgmp.la} in order to ensure dynamic linked C programs aren't
+bloated by a dependency on the C++ standard library, and to avoid any chance
+that the C++ compiler could be required when linking plain C programs.
+
+@file{libgmpxx.la} will use certain internals from @file{libgmp.la} and can
+only be expected to work with @file{libgmp.la} from the same GMP version.
+Future changes to the relevant internals will be accompanied by renaming, so a
+mismatch will cause unresolved symbols rather than perhaps mysterious
+misbehaviour.
+
+In general @file{libgmpxx.la} will be usable only with the C++ compiler that
+built it, since name mangling and runtime support are usually incompatible
+between different compilers.
+
+@item @option{CXX}, @option{CXXFLAGS}
+@cindex C++ compiler
+@cindex @code{CXX}
+@cindex @code{CXXFLAGS}
+When C++ support is enabled, the C++ compiler and its flags can be set with
+variables @samp{CXX} and @samp{CXXFLAGS} in the usual way.  The default for
+@samp{CXX} is the first compiler that works from a list of likely candidates,
+with @command{g++} normally preferred when available.  The default for
+@samp{CXXFLAGS} is to try @samp{CFLAGS}, @samp{CFLAGS} without @samp{-g}, then
+for @command{g++} either @samp{-g -O2} or @samp{-O2}, or for other compilers
+@samp{-g} or nothing.  Trying @samp{CFLAGS} this way is convenient when using
+@samp{gcc} and @samp{g++} together, since the flags for @samp{gcc} will
+usually suit @samp{g++}.
+
+It's important that the C and C++ compilers match, meaning their startup and
+runtime support routines are compatible and that they generate code in the
+same ABI (if there's a choice of ABIs on the system).  @samp{./configure}
+isn't currently able to check these things very well itself, so for that
+reason @samp{--disable-cxx} is the default, to avoid a build failure due to a
+compiler mismatch.  Perhaps this will change in the future.
+
+Incidentally, it's normally not good enough to set @samp{CXX} to the same as
+@samp{CC}.  Although @command{gcc} for instance recognises @file{foo.cc} as
+C++ code, only @command{g++} will invoke the linker the right way when
+building an executable or shared library from C++ object files.
+
+@item Temporary Memory, @option{--enable-alloca=<choice>}
+@cindex Temporary memory
+@cindex Stack overflow
+@cindex @code{alloca}
+@cindex @code{--enable-alloca}
+GMP allocates temporary workspace using one of the following three methods,
+which can be selected with for instance
+@samp{--enable-alloca=malloc-reentrant}.
+
+@itemize @bullet
+@item
+@samp{alloca} - C library or compiler builtin.
+@item
+@samp{malloc-reentrant} - the heap, in a re-entrant fashion.
+@item
+@samp{malloc-notreentrant} - the heap, with global variables.
+@end itemize
+
+For convenience, the following choices are also available.
+@samp{--disable-alloca} is the same as @samp{no}.
+
+@itemize @bullet
+@item
+@samp{yes} - a synonym for @samp{alloca}.
+@item
+@samp{no} - a synonym for @samp{malloc-reentrant}.
+@item
+@samp{reentrant} - @code{alloca} if available, otherwise
+@samp{malloc-reentrant}.  This is the default.
+@item
+@samp{notreentrant} - @code{alloca} if available, otherwise
+@samp{malloc-notreentrant}.
+@end itemize
+
+@code{alloca} is reentrant and fast, and is recommended.  It actually allocates
+just small blocks on the stack; larger ones use malloc-reentrant.
+
+@samp{malloc-reentrant} is, as the name suggests, reentrant and thread safe,
+but @samp{malloc-notreentrant} is faster and should be used if reentrancy is
+not required.
+
+The two malloc methods in fact use the memory allocation functions selected by
+@code{mp_set_memory_functions}, these being @code{malloc} and friends by
+default.  @xref{Custom Allocation}.
+
+An additional choice @samp{--enable-alloca=debug} is available, to help when
+debugging memory related problems (@pxref{Debugging}).
+
+@item FFT Multiplication, @option{--disable-fft}
+@cindex FFT multiplication
+@cindex @code{--disable-fft}
+By default multiplications are done using Karatsuba, 3-way Toom, higher degree
+Toom, and Fermat FFT@.  The FFT is only used on large to very large operands
+and can be disabled to save code size if desired.
+
+@item Assertion Checking, @option{--enable-assert}
+@cindex Assertion checking
+@cindex @code{--enable-assert}
+This option enables some consistency checking within the library.  This can be
+of use while debugging, @pxref{Debugging}.
+
+@item Execution Profiling, @option{--enable-profiling=prof/gprof/instrument}
+@cindex Execution profiling
+@cindex @code{--enable-profiling}
+Enable profiling support, in one of various styles, @pxref{Profiling}.
+
+@item @option{MPN_PATH}
+@cindex @code{MPN_PATH}
+Various assembly versions of each mpn subroutines are provided.  For a given
+CPU, a search is made though a path to choose a version of each.  For example
+@samp{sparcv8} has
+
+@example
+MPN_PATH="sparc32/v8 sparc32 generic"
+@end example
+
+which means look first for v8 code, then plain sparc32 (which is v7), and
+finally fall back on generic C@.  Knowledgeable users with special requirements
+can specify a different path.  Normally this is completely unnecessary.
+
+@item Documentation
+@cindex Documentation formats
+@cindex Texinfo
+The source for the document you're now reading is @file{doc/gmp.texi}, in
+Texinfo format, see @GMPreftop{texinfo, Texinfo}.
+
+@cindex Postscript
+@cindex DVI
+@cindex PDF
+Info format @samp{doc/gmp.info} is included in the distribution.  The usual
+automake targets are available to make PostScript, DVI, PDF and HTML (these
+will require various @TeX{} and Texinfo tools).

+@node ABI and ISA, Notes for Package Builds, Build Options, Installing GMP
+@section ABI and ISA
+@cindex ABI
+@cindex Application Binary Interface
+@cindex ISA
+@cindex Instruction Set Architecture
+
+ABI (Application Binary Interface) refers to the calling conventions between
+functions, meaning what registers are used and what sizes the various C data
+types are.  ISA (Instruction Set Architecture) refers to the instructions and
+registers a CPU has available.
+
+Some 64-bit ISA CPUs have both a 64-bit ABI and a 32-bit ABI defined, the
+latter for compatibility with older CPUs in the family.  GMP supports some
+CPUs like this in both ABIs.  In fact within GMP @samp{ABI} means a
+combination of chip ABI, plus how GMP chooses to use it.  For example in some
+32-bit ABIs, GMP may support a limb as either a 32-bit @code{long} or a 64-bit
+@code{long long}.
+
+By default GMP chooses the best ABI available for a given system, and this
+generally gives significantly greater speed.  But an ABI can be chosen
+explicitly to make GMP compatible with other libraries, or particular
+application requirements.  For example,
+
+@example
+./configure ABI=32
+@end example
+
+In all cases it's vital that all object code used in a given program is
+compiled for the same ABI.
+
+Usually a limb is implemented as a @code{long}.  When a @code{long long} limb
+is used this is encoded in the generated @file{gmp.h}.  This is convenient for
+applications, but it does mean that @file{gmp.h} will vary, and can't be just
+copied around.  @file{gmp.h} remains compiler independent though, since all
+compilers for a particular ABI will be expected to use the same limb type.
+
+Currently no attempt is made to follow whatever conventions a system has for
+installing library or header files built for a particular ABI@.  This will
+probably only matter when installing multiple builds of GMP, and it might be
+as simple as configuring with a special @samp{libdir}, or it might require
+more than that.  Note that builds for different ABIs need to done separately,
+with a fresh @command{./configure} and @command{make} each.

+@item AMD64 (@samp{x86_64})
+@cindex AMD64
+On AMD64 systems supporting both 32-bit and 64-bit modes for applications, the
+following ABI choices are available.
+
+@table @asis
+@item @samp{ABI=64}
+The 64-bit ABI uses 64-bit limbs and pointers and makes full use of the chip
+architecture.  This is the default.  Applications will usually not need
+special compiler flags, but for reference the option is
+
+@example
+gcc  -m64
+@end example
+
+@item @samp{ABI=32}
+The 32-bit ABI is the usual i386 conventions.  This will be slower, and is not
+recommended except for inter-operating with other code not yet 64-bit capable.
+Applications must be compiled with
+
+@example
+gcc  -m32
+@end example
+
+(In GCC 2.95 and earlier there's no @samp{-m32} option, it's the only mode.)
+
+@item @samp{ABI=x32}
+The x32 ABI uses 64-bit limbs but 32-bit pointers.  Like the 64-bit ABI, it
+makes full use of the chip's arithmetic capabilities.  This ABI is not
+supported by all operating systems.
+
+@example
+gcc  -mx32
+@end example
+
+@end table

+@cindex HPPA
+@cindex HP-UX
+@table @asis
+@item @samp{ABI=2.0w}
+The 2.0w ABI uses 64-bit limbs and pointers and is available on HP-UX 11 or
+up.  Applications must be compiled with
+
+@example
+gcc [built for 2.0w]
+cc  +DD64
+@end example
+
+@item @samp{ABI=2.0n}
+The 2.0n ABI means the 32-bit HPPA 1.0 ABI and all its normal calling
+conventions, but with 64-bit instructions permitted within functions.  GMP
+uses a 64-bit @code{long long} for a limb.  This ABI is available on hppa64
+GNU/Linux and on HP-UX 10 or higher.  Applications must be compiled with
+
+@example
+gcc [built for 2.0n]
+cc  +DA2.0 +e
+@end example
+
+Note that current versions of GCC (eg.@: 3.2) don't generate 64-bit
+instructions for @code{long long} operations and so may be slower than for
+2.0w.  (The GMP assembly code is the same though.)

+The 64-bit V9 ABI is available on the various BSD sparc64 ports, recent

+64-bit mode).  GCC 3.2 or higher, or Sun @command{cc} is required.  On

+
+On the BSD sparc64 systems no special options are required, since 64-bits is

+@item @samp{ABI=32}
+For the basic 32-bit ABI, GMP still uses as much of the V9 ISA as it can.  In
+the Sun documentation this combination is known as ``v8plus''.  On GNU/Linux,
+depending on the default @command{gcc} mode, applications may need to be
+compiled with
+
+@example
+gcc  -m32
+@end example
+
+On Solaris, no special compiler options are required for applications, though
+using something like the following is recommended.  (@command{gcc} 2.8 and
+earlier only support @samp{-mv8} though.)
+
+@example
+gcc  -mv8plus
+cc   -xarch=v8plus
+@end example
+@end table
+
+GMP speed is greatest in @samp{ABI=64}, so it's the default where available.
+The speed is partly because there are extra registers available and partly
+because 64-bits is considered the more important case and has therefore had
+better code written for it.
+
+Don't be confused by the names of the @samp{-m} and @samp{-x} compiler
+options, they're called @samp{arch} but effectively control both ABI and ISA@.
+
+On Solaris 2.6 and earlier, only @samp{ABI=32} is available since the kernel
+doesn't save all registers.
+
+On Solaris 2.7 with the kernel in 32-bit mode, a normal native build will
+reject @samp{ABI=64} because the resulting executables won't run.
+@samp{ABI=64} can still be built if desired by making it look like a
+cross-compile, for example

+@cindex Build notes for binary packaging
+@cindex Packaged builds
+
+GMP should present no great difficulties for packaging in a binary
+distribution.
+
+@cindex Libtool versioning
+@cindex Shared library versioning
+Libtool is used to build the library and @samp{-version-info} is set
+appropriately, having started from @samp{3:0:0} in GMP 3.0 (@pxref{Versioning,
+Library interface versions, Library interface versions, libtool, GNU
+Libtool}).
+
+The GMP 4 series will be upwardly binary compatible in each release and will
+be upwardly binary compatible with all of the GMP 3 series.  Additional
+function interfaces may be added in each release, so on systems where libtool
+versioning is not fully checked by the loader an auxiliary mechanism may be
+needed to express that a dynamic linked application depends on a new enough
+GMP.
+
+An auxiliary mechanism may also be needed to express that @file{libgmpxx.la}
+(from @option{--enable-cxx}, @pxref{Build Options}) requires @file{libgmp.la}
+from the same GMP version, since this is not done by the libtool versioning,
+nor otherwise.  A mismatch will result in unresolved symbols from the linker,
+or perhaps the loader.
+
+When building a package for a CPU family, care should be taken to use
+@samp{--host} (or @samp{--build}) to choose the least common denominator among
+the CPUs which might use the package.  For example this might mean plain
+@samp{sparc} (meaning V7) for SPARCs.
+
+For x86s, @option{--enable-fat} sets things up for a fat binary build, making a
+runtime selection of optimized low level routines.  This is a good choice for
+packaging to run on a range of x86 chips.
+
+Users who care about speed will want GMP built for their exact CPU type, to
+make best use of the available optimizations.  Providing a way to suitably
+rebuild a package may be useful.  This could be as simple as making it
+possible for a user to omit @samp{--build} (and @samp{--host}) so
+@samp{./config.guess} will detect the CPU@.  But a way to manually specify a
+@samp{--build} will be wanted for systems where @samp{./config.guess} is
+inexact.
+
+On systems with multiple ABIs, a packaged build will need to decide which
+among the choices is to be provided, see @ref{ABI and ISA}.  A given run of
+@samp{./configure} etc will only build one ABI@.  If a second ABI is also
+required then a second run of @samp{./configure} etc must be made, starting
+from a clean directory tree (@samp{make distclean}).
+
+As noted under ``ABI and ISA'', currently no attempt is made to follow system
+conventions for install locations that vary with ABI, such as
+@file{/usr/lib/sparcv9} for @samp{ABI=64} as opposed to @file{/usr/lib} for
+@samp{ABI=32}.  A package build can override @samp{libdir} and other standard
+variables as necessary.
+
+Note that @file{gmp.h} is a generated file, and will be architecture and ABI
+dependent.  When attempting to install two ABIs simultaneously it will be
+important that an application compile gets the correct @file{gmp.h} for its
+desired ABI@.  If compiler include paths don't vary with ABI options then it
+might be necessary to create a @file{/usr/include/gmp.h} which tests
+preprocessor symbols and chooses the correct actual @file{gmp.h}.

+
+Note that the @samp{--disable-static} is necessary because in a shared build

+@cindex Compaq C++
+Compaq C++ on OSF 5.1 has two flavours of @code{iostream}, a standard one and
+an old pre-standard one (see @samp{man iostream_intro}).  GMP can only use the
+standard one, which unfortunately is not the default but must be selected by

+@cindex DLLs
+@cindex MS Windows
+@cindex Windows
+On systems @samp{*-*-cygwin*}, @samp{*-*-mingw*} and @samp{*-*-pw32*} by
+default GMP builds only a static library, but a DLL can be built instead using

+@example

+@end example
+
+Static and DLL libraries can't both be built, since certain export directives
+in @file{gmp.h} must be different.
+
+A MINGW DLL build of GMP can be used with Microsoft C@.  Libtool doesn't
+install a @file{.lib} format import library, but it can be created with MS
+@command{lib} as follows, and copied to the install directory.  Similarly for
+@file{libmp} and @file{libgmpxx}.
+
+@example
+cd .libs
+lib /def:libgmp-3.dll.def /out:libgmp-3.lib
+@end example
+
+MINGW uses the C runtime library @samp{msvcrt.dll} for I/O, so applications
+wanting to use the GMP I/O routines must be compiled with @samp{cl /MD} to do
+the same.  If one of the other C runtime library choices provided by MS C is

+
+@item Power CPU Types
+@cindex Power/PowerPC
+In GMP, CPU types @samp{power*} and @samp{powerpc*} will each use instructions
+not available on the other, so it's important to choose the right one for the
+CPU that will be used.  Currently GMP has no assembly code support for using
+just the common instruction subset.  To get executables that run on both, the
+current suggestion is to use the generic C code (@option{--disable-assembly}),
+possibly with appropriate compiler options (like @samp{-mcpu=common} for
+@command{gcc}).  CPU @samp{rs6000} (which is not a CPU but a family of
+workstations) is accepted by @file{config.sub}, but is currently equivalent to
+@option{--disable-assembly}.
+
+@item Sparc CPU Types
+@cindex Sparc
+@samp{sparcv8} or @samp{supersparc} on relevant systems will give a
+significant performance increase over the V7 code selected by plain
+@samp{sparc}.
+
+@item Sparc App Regs
+@cindex Sparc
+The GMP assembly code for both 32-bit and 64-bit Sparc clobbers the
+``application registers'' @code{g2}, @code{g3} and @code{g4}, the same way
+that the GCC default @samp{-mapp-regs} does (@pxref{SPARC Options,, SPARC
+Options, gcc, Using the GNU Compiler Collection (GCC)}).
+
+This makes that code unsuitable for use with the special V9
+@samp{-mcmodel=embmedany} (which uses @code{g4} as a data segment pointer), and
+for applications wanting to use those registers for special purposes.  In these
+cases the only suggestion currently is to build GMP with
+@option{--disable-assembly} to avoid the assembly code.
+
+@item SunOS 4
+@cindex SunOS
+@command{/usr/bin/m4} lacks various features needed to process @file{.asm}
+files, and instead @samp{./configure} will automatically use
+@command{/usr/5bin/m4}, which we believe is always available (if not then use
+GNU m4).
+
+@item x86 CPU Types
+@cindex x86
+@cindex 80x86
+@cindex i386
+@samp{i586}, @samp{pentium} or @samp{pentiummmx} code is good for its intended
+P5 Pentium chips, but quite slow when run on Intel P6 class chips (PPro, P-II,
+P-III)@.  @samp{i386} is a better choice when making binaries that must run on
+both.
+
+@item x86 MMX and SSE2 Code
+@cindex MMX
+@cindex SSE2
+If the CPU selected has MMX code but the assembler doesn't support it, a
+warning is given and non-MMX code is used instead.  This will be an inferior
+build, since the MMX code that's present is there because it's faster than the
+corresponding plain integer code.  The same applies to SSE2.
+
+Old versions of @samp{gas} don't support MMX instructions, in particular
+version 1.92.3 that comes with FreeBSD 2.2.8 or the more recent OpenBSD 3.1
+doesn't.
+
+Solaris 2.6 and 2.7 @command{as} generate incorrect object code for register
+to register @code{movq} instructions, and so can't be used for MMX code.
+Install a recent @command{gas} if MMX code is wanted on these systems.

+@cindex @file{gmp.h}
+@cindex Include files
+@cindex @code{#include}
+All declarations needed to use GMP are collected in the include file
+@file{gmp.h}.  It is designed to work with both C and C++ compilers.
+
+@example
+#include <gmp.h>
+@end example
+
+@cindex @code{stdio.h}
+Note however that prototypes for GMP functions with @code{FILE *} parameters
+are only provided if @code{<stdio.h>} is included too.
+
+@example
+#include <stdio.h>
+#include <gmp.h>
+@end example
+
+@cindex @code{stdarg.h}
+Likewise @code{<stdarg.h>} is required for prototypes with @code{va_list}
+parameters, such as @code{gmp_vprintf}.  And @code{<obstack.h>} for prototypes
+with @code{struct obstack} parameters, such as @code{gmp_obstack_printf}, when

+@cindex Libraries
+@cindex Linking
+@cindex @code{libgmp}
+All programs using GMP must link against the @file{libgmp} library.  On a
+typical Unix-like system this can be done with @samp{-lgmp}, for example
+
+@example
+gcc myprogram.c -lgmp
+@end example
+
+@cindex @code{libgmpxx}
+GMP C++ functions are in a separate @file{libgmpxx} library.  This is built
+and installed if C++ support has been enabled (@pxref{Build Options}).  For
+example,
+
+@example
+g++ mycxxprog.cc -lgmpxx -lgmp
+@end example
+
+@cindex Libtool
+GMP is built using Libtool and an application can use that to link if desired,
+@GMPpxreftop{libtool, GNU Libtool}.
+
+If GMP has been installed to a non-standard location then it may be necessary
+to use @samp{-I} and @samp{-L} compiler options to point to the right

+@node Nomenclature and Types, Function Classes, Headers and Libraries, GMP Basics
+@section Nomenclature and Types
+@cindex Nomenclature
+@cindex Types
+
+@cindex Integer
+@tindex @code{mpz_t}
+In this manual, @dfn{integer} usually means a multiple precision integer, as
+defined by the GMP library.  The C data type for such integers is @code{mpz_t}.
+Here are some examples of how to declare such integers:
+
+@example
+mpz_t sum;
+
+struct foo @{ mpz_t x, y; @};
+
+mpz_t vec[20];
+@end example
+
+@cindex Rational number
+@tindex @code{mpq_t}
+@dfn{Rational number} means a multiple precision fraction.  The C data type
+for these fractions is @code{mpq_t}.  For example:
+
+@example
+mpq_t quotient;
+@end example
+
+@cindex Floating-point number
+@tindex @code{mpf_t}
+@dfn{Floating point number} or @dfn{Float} for short, is an arbitrary precision
+mantissa with a limited precision exponent.  The C data type for such objects
+is @code{mpf_t}.  For example:
+
+@example
+mpf_t fp;
+@end example
+
+@tindex @code{mp_exp_t}
+The floating point functions accept and return exponents in the C type
+@code{mp_exp_t}.  Currently this is usually a @code{long}, but on some systems
+it's an @code{int} for efficiency.
+
+@cindex Limb
+@tindex @code{mp_limb_t}
+A @dfn{limb} means the part of a multi-precision number that fits in a single
+machine word.  (We chose this word because a limb of the human body is
+analogous to a digit, only larger, and containing several digits.)  Normally a
+limb is 32 or 64 bits.  The C data type for a limb is @code{mp_limb_t}.
+
+@tindex @code{mp_size_t}
+Counts of limbs of a multi-precision number represented in the C type
+@code{mp_size_t}.  Currently this is normally a @code{long}, but on some
+systems it's an @code{int} for efficiency, and on some systems it will be
+@code{long long} in the future.
+
+@tindex @code{mp_bitcnt_t}
+Counts of bits of a multi-precision number are represented in the C type
+@code{mp_bitcnt_t}.  Currently this is always an @code{unsigned long}, but on
+some systems it will be an @code{unsigned long long} in the future.
+
+@cindex Random state
+@tindex @code{gmp_randstate_t}
+@dfn{Random state} means an algorithm selection and current state data.  The C
+data type for such objects is @code{gmp_randstate_t}.  For example:
+
+@example
+gmp_randstate_t rstate;
+@end example
+
+Also, in general @code{mp_bitcnt_t} is used for bit counts and ranges, and
+@code{size_t} is used for byte or character counts.
+
+
+@node Function Classes, Variable Conventions, Nomenclature and Types, GMP Basics
+@section Function Classes
+@cindex Function classes
+
+There are six classes of functions in the GMP library:
+
+@enumerate
+@item
+Functions for signed integer arithmetic, with names beginning with
+@code{mpz_}.  The associated type is @code{mpz_t}.  There are about 150
+functions in this class.  (@pxref{Integer Functions})
+
+@item
+Functions for rational number arithmetic, with names beginning with
+@code{mpq_}.  The associated type is @code{mpq_t}.  There are about 35
+functions in this class, but the integer functions can be used for arithmetic
+on the numerator and denominator separately.  (@pxref{Rational Number
+Functions})
+
+@item
+Functions for floating-point arithmetic, with names beginning with
+@code{mpf_}.  The associated type is @code{mpf_t}.  There are about 70
+functions is this class.  (@pxref{Floating-point Functions})
+
+@item
+Fast low-level functions that operate on natural numbers.  These are used by
+the functions in the preceding groups, and you can also call them directly
+from very time-critical user programs.  These functions' names begin with
+@code{mpn_}.  The associated type is array of @code{mp_limb_t}.  There are
+about 60 (hard-to-use) functions in this class.  (@pxref{Low-level Functions})
+
+@item
+Miscellaneous functions.  Functions for setting up custom allocation and
+functions for generating random numbers.  (@pxref{Custom Allocation}, and
+@pxref{Random Number Functions})
+@end enumerate
+
+
+@node Variable Conventions, Parameter Conventions, Function Classes, GMP Basics
+@section Variable Conventions
+@cindex Variable conventions
+@cindex Conventions for variables
+
+GMP functions generally have output arguments before input arguments.  This
+notation is by analogy with the assignment operator.
+
+GMP lets you use the same variable for both input and output in one call.  For
+example, the main function for integer multiplication, @code{mpz_mul}, can be
+used to square @code{x} and put the result back in @code{x} with
+
+@example
+mpz_mul (x, x, x);
+@end example
+
+Before you can assign to a GMP variable, you need to initialize it by calling
+one of the special initialization functions.  When you're done with a
+variable, you need to clear it out, using one of the functions for that
+purpose.  Which function to use depends on the type of variable.  See the
+chapters on integer functions, rational number functions, and floating-point
+functions for details.
+
+A variable should only be initialized once, or at least cleared between each
+initialization.  After a variable has been initialized, it may be assigned to
+any number of times.
+
+For efficiency reasons, avoid excessive initializing and clearing.  In
+general, initialize near the start of a function and clear near the end.  For
+example,
+
+@example
+void
+foo (void)
+@{
+  mpz_t  n;
+  int    i;
+  mpz_init (n);
+  for (i = 1; i < 100; i++)
+    @{
+      mpz_mul (n, @dots{});
+      mpz_fdiv_q (n, @dots{});
+      @dots{}
+    @}
+  mpz_clear (n);
+@}
+@end example
+
+GMP types like @code{mpz_t} are implemented as one-element arrays of certain
+structures.  Declaring a variable creates an object with the fields GMP needs,
+but variables are normally manipulated by using the pointer to the object.  For
+both behavior and efficiency reasons, it is discouraged to make copies of the
+GMP object itself (either directly or via aggregate objects containing such GMP
+objects).  If copies are done, all of them must be used read-only; using a copy
+as the output of some function will invalidate all the other copies.  Note that
+the actual fields in each @code{mpz_t} etc are for internal use only and should
+not be accessed directly by code that expects to be compatible with future GMP
+releases.
+
+@node Parameter Conventions, Memory Management, Variable Conventions, GMP Basics
+@section Parameter Conventions
+@cindex Parameter conventions
+@cindex Conventions for parameters
+
+When a GMP variable is used as a function parameter, it's effectively a
+call-by-reference, meaning that when the function stores a value there it will
+change the original in the caller.  Parameters which are input-only can be
+designated @code{const} to provoke a compiler error or warning on attempting to
+modify them.
+
+When a function is going to return a GMP result, it should designate a
+parameter that it sets, like the library functions do.  More than one value
+can be returned by having more than one output parameter, again like the
+library functions.  A @code{return} of an @code{mpz_t} etc doesn't return the
+object, only a pointer, and this is almost certainly not what's wanted.
+
+Here's an example accepting an @code{mpz_t} parameter, doing a calculation,
+and storing the result to the indicated parameter.
+
+@example
+void
+foo (mpz_t result, const mpz_t param, unsigned long n)
+@{
+  unsigned long  i;
+  mpz_mul_ui (result, param, n);
+  for (i = 1; i < n; i++)
+    mpz_add_ui (result, result, i*7);
+@}
+
+int
+main (void)
+@{
+  mpz_t  r, n;
+  mpz_init (r);
+  mpz_init_set_str (n, "123456", 0);
+  foo (r, n, 20L);
+  gmp_printf ("%Zd\n", r);
+  return 0;
+@}
+@end example
+
+Our function @code{foo} works even if its caller passes the same variable for
+@code{param} and @code{result}, just like the library functions.  But
+sometimes it's tricky to make that work, and an application might not want to
+bother supporting that sort of thing.
+
+Since GMP types are implemented as one-element arrays, using a GMP variable as
+a parameter passes a pointer to the object. Hence the call-by-reference.
+

+@need 1000
+@node Memory Management, Reentrancy, Parameter Conventions, GMP Basics
+@section Memory Management
+@cindex Memory management
+
+The GMP types like @code{mpz_t} are small, containing only a couple of sizes,
+and pointers to allocated data.  Once a variable is initialized, GMP takes
+care of all space allocation.  Additional space is allocated whenever a
+variable doesn't have enough.
+
+@code{mpz_t} and @code{mpq_t} variables never reduce their allocated space.
+Normally this is the best policy, since it avoids frequent reallocation.
+Applications that need to return memory to the heap at some particular point
+can use @code{mpz_realloc2}, or clear variables no longer needed.
+
+@code{mpf_t} variables, in the current implementation, use a fixed amount of
+space, determined by the chosen precision and allocated at initialization, so
+their size doesn't change.
+
+All memory is allocated using @code{malloc} and friends by default, but this
+can be changed, see @ref{Custom Allocation}.  Temporary memory on the stack is
+also used (via @code{alloca}), but this can be changed at build-time if
+desired, see @ref{Build Options}.

+@node Reentrancy, Useful Macros and Constants, Memory Management, GMP Basics
+@section Reentrancy
+@cindex Reentrancy
+@cindex Thread safety
+@cindex Multi-threading
+
+@noindent
+GMP is reentrant and thread-safe, with some exceptions:
+
+@itemize @bullet
+@item
+If configured with @option{--enable-alloca=malloc-notreentrant} (or with
+@option{--enable-alloca=notreentrant} when @code{alloca} is not available),
+then naturally GMP is not reentrant.
+
+@item
+@code{mpf_set_default_prec} and @code{mpf_init} use a global variable for the
+selected precision.  @code{mpf_init2} can be used instead, and in the C++
+interface an explicit precision to the @code{mpf_class} constructor.
+
+@item
+@code{mpz_random} and the other old random number functions use a global
+random state and are hence not reentrant.  The newer random number functions
+that accept a @code{gmp_randstate_t} parameter can be used instead.
+
+@item
+@code{gmp_randinit} (obsolete) returns an error indication through a global
+variable, which is not thread safe.  Applications are advised to use
+@code{gmp_randinit_default} or @code{gmp_randinit_lc_2exp} instead.
+
+@item
+@code{mp_set_memory_functions} uses global variables to store the selected
+memory allocation functions.
+
+@item
+If the memory allocation functions set by a call to
+@code{mp_set_memory_functions} (or @code{malloc} and friends by default) are
+not reentrant, then GMP will not be reentrant either.
+
+@item
+If the standard I/O functions such as @code{fwrite} are not reentrant then the
+GMP I/O functions using them will not be reentrant either.
+
+@item
+It's safe for two threads to read from the same GMP variable simultaneously,
+but it's not safe for one to read while another might be writing, nor for
+two threads to write simultaneously.  It's not safe for two threads to
+generate a random number from the same @code{gmp_randstate_t} simultaneously,
+since this involves an update of that variable.

+@c undocumented in previous releases.
+
+@c @item The functions @code{mpz_cmp_ui}, @code{mpz_cmp_si}, and @code{mpq_cmp_ui}

+@item Small Operands
+@cindex Small operands
+On small operands, the time for function call overheads and memory allocation
+can be significant in comparison to actual calculation.  This is unavoidable
+in a general purpose variable precision library, although GMP attempts to be
+as efficient as it can on both large and small operands.
+
+@item Static Linking
+@cindex Static linking
+On some CPUs, in particular the x86s, the static @file{libgmp.a} should be
+used for maximum speed, since the PIC code in the shared @file{libgmp.so} will
+have a small overhead on each function call and global data address.  For many
+programs this will be insignificant, but for long calculations there's a gain
+to be had.
+
+@item Initializing and Clearing
+@cindex Initializing and clearing
+Avoid excessive initializing and clearing of variables, since this can be
+quite time consuming, especially in comparison to otherwise fast operations
+like addition.
+
+A language interpreter might want to keep a free list or stack of
+initialized variables ready for use.  It should be possible to integrate
+something like that with a garbage collector too.
+
+@item Reallocations
+@cindex Reallocations
+An @code{mpz_t} or @code{mpq_t} variable used to hold successively increasing
+values will have its memory repeatedly @code{realloc}ed, which could be quite
+slow or could fragment memory, depending on the C library.  If an application
+can estimate the final size then @code{mpz_init2} or @code{mpz_realloc2} can
+be called to allocate the necessary space from the beginning
+(@pxref{Initializing Integers}).
+
+It doesn't matter if a size set with @code{mpz_init2} or @code{mpz_realloc2}
+is too small, since all functions will do a further reallocation if necessary.
+Badly overestimating memory required will waste space though.
+
+@item @code{2exp} Functions
+@cindex @code{2exp} functions
+It's up to an application to call functions like @code{mpz_mul_2exp} when
+appropriate.  General purpose functions like @code{mpz_mul} make no attempt to
+identify powers of two or other special forms, because such inputs will
+usually be very rare and testing every time would be wasteful.
+
+@item @code{ui} and @code{si} Functions
+@cindex @code{ui} and @code{si} functions
+The @code{ui} functions and the small number of @code{si} functions exist for
+convenience and should be used where applicable.  But if for example an
+@code{mpz_t} contains a value that fits in an @code{unsigned long} there's no
+need extract it and call a @code{ui} function, just use the regular @code{mpz}
+function.
+
+@item In-Place Operations
+@cindex In-place operations
+@code{mpz_abs}, @code{mpq_abs}, @code{mpf_abs}, @code{mpz_neg}, @code{mpq_neg}
+and @code{mpf_neg} are fast when used for in-place operations like
+@code{mpz_abs(x,x)}, since in the current implementation only a single field
+of @code{x} needs changing.  On suitable compilers (GCC for instance) this is
+inlined too.
+
+@code{mpz_add_ui}, @code{mpz_sub_ui}, @code{mpf_add_ui} and @code{mpf_sub_ui}
+benefit from an in-place operation like @code{mpz_add_ui(x,x,y)}, since
+usually only one or two limbs of @code{x} will need to be changed.  The same
+applies to the full precision @code{mpz_add} etc if @code{y} is small.  If
+@code{y} is big then cache locality may be helped, but that's all.
+
+@code{mpz_mul} is currently the opposite, a separate destination is slightly
+better.  A call like @code{mpz_mul(x,x,y)} will, unless @code{y} is only one
+limb, make a temporary copy of @code{x} before forming the result.  Normally
+that copying will only be a tiny fraction of the time for the multiply, so
+this is not a particularly important consideration.
+
+@code{mpz_set}, @code{mpq_set}, @code{mpq_set_num}, @code{mpf_set}, etc, make
+no attempt to recognise a copy of something to itself, so a call like
+@code{mpz_set(x,x)} will be wasteful.  Naturally that would never be written
+deliberately, but if it might arise from two pointers to the same object then
+a test to avoid it might be desirable.
+
+@example
+if (x != y)
+  mpz_set (x, y);
+@end example
+
+Note that it's never worth introducing extra @code{mpz_set} calls just to get
+in-place operations.  If a result should go to a particular variable then just
+direct it there and let GMP take care of data movement.
+
+@item Divisibility Testing (Small Integers)
+@cindex Divisibility testing
+@code{mpz_divisible_ui_p} and @code{mpz_congruent_ui_p} are the best functions
+for testing whether an @code{mpz_t} is divisible by an individual small
+integer.  They use an algorithm which is faster than @code{mpz_tdiv_ui}, but
+which gives no useful information about the actual remainder, only whether
+it's zero (or a particular value).
+
+However when testing divisibility by several small integers, it's best to take
+a remainder modulo their product, to save multi-precision operations.  For
+instance to test whether a number is divisible by any of 23, 29 or 31 take a
+remainder modulo @math{23@times{}29@times{}31 = 20677} and then test that.
+
+The division functions like @code{mpz_tdiv_q_ui} which give a quotient as well
+as a remainder are generally a little slower than the remainder-only functions
+like @code{mpz_tdiv_ui}.  If the quotient is only rarely wanted then it's
+probably best to just take a remainder and then go back and calculate the
+quotient if and when it's wanted (@code{mpz_divexact_ui} can be used if the
+remainder is zero).
+
+@item Rational Arithmetic
+@cindex Rational arithmetic
+The @code{mpq} functions operate on @code{mpq_t} values with no common factors
+in the numerator and denominator.  Common factors are checked-for and cast out
+as necessary.  In general, cancelling factors every time is the best approach
+since it minimizes the sizes for subsequent operations.
+
+However, applications that know something about the factorization of the
+values they're working with might be able to avoid some of the GCDs used for
+canonicalization, or swap them for divisions.  For example when multiplying by
+a prime it's enough to check for factors of it in the denominator instead of
+doing a full GCD@.  Or when forming a big product it might be known that very
+little cancellation will be possible, and so canonicalization can be left to
+the end.
+
+The @code{mpq_numref} and @code{mpq_denref} macros give access to the
+numerator and denominator to do things outside the scope of the supplied
+@code{mpq} functions.  @xref{Applying Integer Functions}.
+
+The canonical form for rationals allows mixed-type @code{mpq_t} and integer
+additions or subtractions to be done directly with multiples of the
+denominator.  This will be somewhat faster than @code{mpq_add}.  For example,
+
+@example
+/* mpq increment */
+mpz_add (mpq_numref(q), mpq_numref(q), mpq_denref(q));
+
+/* mpq += unsigned long */
+mpz_addmul_ui (mpq_numref(q), mpq_denref(q), 123UL);
+
+/* mpq -= mpz */
+mpz_submul (mpq_numref(q), mpq_denref(q), z);
+@end example
+
+@item Number Sequences
+@cindex Number sequences
+Functions like @code{mpz_fac_ui}, @code{mpz_fib_ui} and @code{mpz_bin_uiui}
+are designed for calculating isolated values.  If a range of values is wanted
+it's probably best to call to get a starting point and iterate from there.
+
+@item Text Input/Output
+@cindex Text input/output
+Hexadecimal or octal are suggested for input or output in text form.
+Power-of-2 bases like these can be converted much more efficiently than other
+bases, like decimal.  For big numbers there's usually nothing of particular
+interest to be seen in the digits, so the base doesn't matter much.
+
+Maybe we can hope octal will one day become the normal base for everyday use,
+as proposed by King Charles XII of Sweden and later reformers.

+@cindex Debugging
+
+@table @asis
+@item Stack Overflow
+@cindex Stack overflow
+@cindex Segmentation violation
+@cindex Bus error
+Depending on the system, a segmentation violation or bus error might be the
+only indication of stack overflow.  See @samp{--enable-alloca} choices in
+@ref{Build Options}, for how to address this.
+
+In new enough versions of GCC, @samp{-fstack-check} may be able to ensure an
+overflow is recognised by the system before too much damage is done, or
+@samp{-fstack-limit-symbol} or @samp{-fstack-limit-register} may be able to
+add checking if the system itself doesn't do any (@pxref{Code Gen Options,,
+Options for Code Generation, gcc, Using the GNU Compiler Collection (GCC)}).
+These options must be added to the @samp{CFLAGS} used in the GMP build
+(@pxref{Build Options}), adding them just to an application will have no
+effect.  Note also they're a slowdown, adding overhead to each function call
+and each stack allocation.
+
+@item Heap Problems
+@cindex Heap problems
+@cindex Malloc problems
+The most likely cause of application problems with GMP is heap corruption.
+Failing to @code{init} GMP variables will have unpredictable effects, and
+corruption arising elsewhere in a program may well affect GMP@.  Initializing
+GMP variables more than once or failing to clear them will cause memory leaks.
+
+@cindex Malloc debugger
+In all such cases a @code{malloc} debugger is recommended.  On a GNU or BSD
+system the standard C library @code{malloc} has some diagnostic facilities,
+see @ref{Allocation Debugging,, Allocation Debugging, libc, The GNU C Library
+Reference Manual}, or @samp{man 3 malloc}.  Other possibilities, in no
+particular order, include
+
+@display
+@uref{http://cs.ecs.baylor.edu/~donahoo/tools/ccmalloc/}
+@uref{http://dmalloc.com/}
+@uref{https://wiki.gnome.org/Apps/MemProf}
+@end display
+
+The GMP default allocation routines in @file{memory.c} also have a simple
+sentinel scheme which can be enabled with @code{#define DEBUG} in that file.
+This is mainly designed for detecting buffer overruns during GMP development,
+but might find other uses.
+
+@item Stack Backtraces
+@cindex Stack backtrace
+On some systems the compiler options GMP uses by default can interfere with
+debugging.  In particular on x86 and 68k systems @samp{-fomit-frame-pointer}
+is used and this generally inhibits stack backtracing.  Recompiling without
+such options may help while debugging, though the usual caveats about it
+potentially moving a memory problem or hiding a compiler bug will apply.
+
+@item GDB, the GNU Debugger
+@cindex GDB
+@cindex GNU Debugger
+A sample @file{.gdbinit} is included in the distribution, showing how to call
+some undocumented dump functions to print GMP variables from within GDB@.  Note
+that these functions shouldn't be used in final application code since they're
+undocumented and may be subject to incompatible changes in future versions of
+GMP.
+
+@item Source File Paths
+GMP has multiple source files with the same name, in different directories.
+For example @file{mpz}, @file{mpq} and @file{mpf} each have an
+@file{init.c}.  If the debugger can't already determine the right one it may
+help to build with absolute paths on each C file.  One way to do that is to
+use a separate object directory with an absolute path to the source directory.
+
+@example
+cd /my/build/dir
+/my/source/dir/gmp-@value{VERSION}/configure
+@end example
+
+This works via @code{VPATH}, and might require GNU @command{make}.
+Alternately it might be possible to change the @code{.c.lo} rules
+appropriately.
+
+@item Assertion Checking
+@cindex Assertion checking
+The build option @option{--enable-assert} is available to add some consistency
+checks to the library (see @ref{Build Options}).  These are likely to be of
+limited value to most applications.  Assertion failures are just as likely to
+indicate memory corruption as a library or compiler bug.
+
+Applications using the low-level @code{mpn} functions, however, will benefit
+from @option{--enable-assert} since it adds checks on the parameters of most
+such functions, many of which have subtle restrictions on their usage.  Note
+however that only the generic C code has checks, not the assembly code, so
+@option{--disable-assembly} should be used for maximum checking.
+
+@item Temporary Memory Checking
+The build option @option{--enable-alloca=debug} arranges that each block of
+temporary memory in GMP is allocated with a separate call to @code{malloc} (or
+the allocation function set with @code{mp_set_memory_functions}).
+
+This can help a malloc debugger detect accesses outside the intended bounds,
+or detect memory not released.  In a normal build, on the other hand,
+temporary memory is allocated in blocks which GMP divides up for its own use,
+or may be allocated with a compiler builtin @code{alloca} which will go
+nowhere near any malloc debugger hooks.
+
+@item Maximum Debuggability
+To summarize the above, a GMP build for maximum debuggability would be
+
+@example
+./configure --disable-shared --enable-assert \
+  --enable-alloca=debug --disable-assembly CFLAGS=-g
+@end example
+
+For C++, add @samp{--enable-cxx CXXFLAGS=-g}.
+
+@item Checker
+@cindex Checker
+@cindex GCC Checker
+The GCC checker (@uref{https://savannah.nongnu.org/projects/checker/}) can be
+used with GMP@.  It contains a stub library which means GMP applications
+compiled with checker can use a normal GMP build.
+
+A build of GMP with checking within GMP itself can be made.  This will run
+very very slowly.  On GNU/Linux for example,
+
+@cindex @command{checkergcc}
+@example
+./configure --disable-assembly CC=checkergcc
+@end example
+
+@option{--disable-assembly} must be used, since the GMP assembly code doesn't
+support the checking scheme.  The GMP C++ features cannot be used, since
+current versions of checker (0.9.9.1) don't yet support the standard C++
+library.
+
+@item Valgrind
+@cindex Valgrind
+Valgrind (@uref{http://valgrind.org/}) is a memory checker for x86, ARM, MIPS,
+PowerPC, and S/390.  It translates and emulates machine instructions to do
+strong checks for uninitialized data (at the level of individual bits), memory
+accesses through bad pointers, and memory leaks.
+
+Valgrind does not always support every possible instruction, in particular
+ones recently added to an ISA.  Valgrind might therefore be incompatible with
+a recent GMP or even a less recent GMP which is compiled using a recent GCC.
+
+GMP's assembly code sometimes promotes a read of the limbs to some larger size,
+for efficiency.  GMP will do this even at the start and end of a multilimb
+operand, using naturally aligned operations on the larger type.  This may lead
+to benign reads outside of allocated areas, triggering complaints from
+Valgrind.  Valgrind's option @samp{--partial-loads-ok=yes} should help.
+
+@item Other Problems
+Any suspected bug in GMP itself should be isolated to make sure it's not an
+application problem, see @ref{Reporting Bugs}.
+@end table

+
+@node Profiling, Autoconf, Debugging, GMP Basics
+@section Profiling
+@cindex Profiling
+@cindex Execution profiling
+@cindex @code{--enable-profiling}
+
+Running a program under a profiler is a good way to find where it's spending
+most time and where improvements can be best sought.  The profiling choices
+for a GMP build are as follows.
+
+@table @asis
+@item @samp{--disable-profiling}
+The default is to add nothing special for profiling.
+
+It should be possible to just compile the mainline of a program with @code{-p}
+and use @command{prof} to get a profile consisting of timer-based sampling of
+the program counter.  Most of the GMP assembly code has the necessary symbol
+information.
+
+This approach has the advantage of minimizing interference with normal program
+operation, but on most systems the resolution of the sampling is quite low (10
+milliseconds for instance), requiring long runs to get accurate information.
+
+@item @samp{--enable-profiling=prof}
+@cindex @code{prof}
+Build with support for the system @command{prof}, which means @samp{-p} added
+to the @samp{CFLAGS}.
+
+This provides call counting in addition to program counter sampling, which
+allows the most frequently called routines to be identified, and an average
+time spent in each routine to be determined.
+
+The x86 assembly code has support for this option, but on other processors
+the assembly routines will be as if compiled without @samp{-p} and therefore
+won't appear in the call counts.
+
+On some systems, such as GNU/Linux, @samp{-p} in fact means @samp{-pg} and in
+this case @samp{--enable-profiling=gprof} described below should be used
+instead.
+
+@item @samp{--enable-profiling=gprof}
+@cindex @code{gprof}
+Build with support for @command{gprof}, which means @samp{-pg} added to the
+@samp{CFLAGS}.
+
+This provides call graph construction in addition to call counting and program
+counter sampling, which makes it possible to count calls coming from different
+locations.  For example the number of calls to @code{mpn_mul} from
+@code{mpz_mul} versus the number from @code{mpf_mul}.  The program counter
+sampling is still flat though, so only a total time in @code{mpn_mul} would be
+accumulated, not a separate amount for each call site.
+
+The x86 assembly code has support for this option, but on other processors
+the assembly routines will be as if compiled without @samp{-pg} and therefore
+not be included in the call counts.
+
+On x86 and m68k systems @samp{-pg} and @samp{-fomit-frame-pointer} are
+incompatible, so the latter is omitted from the default flags in that case,
+which might result in poorer code generation.
+
+Incidentally, it should be possible to use the @command{gprof} program with a
+plain @samp{--enable-profiling=prof} build.  But in that case only the
+@samp{gprof -p} flat profile and call counts can be expected to be valid, not
+the @samp{gprof -q} call graph.
+
+@item @samp{--enable-profiling=instrument}
+@cindex @code{-finstrument-functions}
+@cindex @code{instrument-functions}
+Build with the GCC option @samp{-finstrument-functions} added to the
+@samp{CFLAGS} (@pxref{Code Gen Options,, Options for Code Generation, gcc,
+Using the GNU Compiler Collection (GCC)}).
+
+This inserts special instrumenting calls at the start and end of each
+function, allowing exact timing and full call graph construction.
+
+This instrumenting is not normally a standard system feature and will require
+support from an external library, such as
+
+@cindex FunctionCheck
+@cindex fnccheck
+@display
+@uref{https://sourceforge.net/projects/fnccheck/}
+@end display
+
+This should be included in @samp{LIBS} during the GMP configure so that test
+programs will link.  For example,
+
+@example
+./configure --enable-profiling=instrument LIBS=-lfc
+@end example
+
+On a GNU system the C library provides dummy instrumenting functions, so
+programs compiled with this option will link.  In this case it's only
+necessary to ensure the correct library is added when linking an application.
+
+The x86 assembly code supports this option, but on other processors the
+assembly routines will be as if compiled without
+@samp{-finstrument-functions} meaning time spent in them will effectively be
+attributed to their caller.
+@end table
+
+
+@node Autoconf, Emacs, Profiling, GMP Basics
+@section Autoconf
+@cindex Autoconf
+
+Autoconf based applications can easily check whether GMP is installed.  The
+only thing to be noted is that GMP library symbols from version 3 onwards have
+prefixes like @code{__gmpz}.  The following therefore would be a simple test,
+
+@cindex @code{AC_CHECK_LIB}
+@example
+AC_CHECK_LIB(gmp, __gmpz_init)
+@end example
+
+This just uses the default @code{AC_CHECK_LIB} actions for found or not found,
+but an application that must have GMP would want to generate an error if not
+found.  For example,
+
+@example
+AC_CHECK_LIB(gmp, __gmpz_init, ,
+  [AC_MSG_ERROR([GNU MP not found, see https://gmplib.org/])])
+@end example
+
+If functions added in some particular version of GMP are required, then one of
+those can be used when checking.  For example @code{mpz_mul_si} was added in
+GMP 3.1,
+
+@example
+AC_CHECK_LIB(gmp, __gmpz_mul_si, ,
+  [AC_MSG_ERROR(
+  [GNU MP not found, or not 3.1 or up, see https://gmplib.org/])])
+@end example
+
+An alternative would be to test the version number in @file{gmp.h} using say
+@code{AC_EGREP_CPP}.  That would make it possible to test the exact version,
+if some particular sub-minor release is known to be necessary.
+
+In general it's recommended that applications should simply demand a new
+enough GMP rather than trying to provide supplements for features not
+available in past versions.
+
+Occasionally an application will need or want to know the size of a type at
+configuration or preprocessing time, not just with @code{sizeof} in the code.
+This can be done in the normal way with @code{mp_limb_t} etc, but GMP 4.0 or
+up is best for this, since prior versions needed certain @samp{-D} defines on
+systems using a @code{long long} limb.  The following would suit Autoconf 2.50
+or up,
+
+@example
+AC_CHECK_SIZEOF(mp_limb_t, , [#include <gmp.h>])

+@section Initialization Functions
+@cindex Integer initialization functions
+@cindex Initialization functions
+
+The functions for integer arithmetic assume that all integer objects are
+initialized.  You do that by calling the function @code{mpz_init}.  For
+example,
+
+@example
+@{
+  mpz_t integ;
+  mpz_init (integ);
+  @dots{}
+  mpz_add (integ, @dots{});
+  @dots{}
+  mpz_sub (integ, @dots{});
+
+  /* Unless the program is about to exit, do ... */
+  mpz_clear (integ);
+@}
+@end example
+
+As you can see, you can store new values any number of times, once an
+object is initialized.
+
+@deftypefun void mpz_init (mpz_t @var{x})
+Initialize @var{x}, and set its value to 0.
+@end deftypefun
+
+@deftypefun void mpz_inits (mpz_t @var{x}, ...)
+Initialize a NULL-terminated list of @code{mpz_t} variables, and set their
+values to 0.
+@end deftypefun
+
+@deftypefun void mpz_init2 (mpz_t @var{x}, mp_bitcnt_t @var{n})
+Initialize @var{x}, with space for @var{n}-bit numbers, and set its value to 0.
+Calling this function instead of @code{mpz_init} or @code{mpz_inits} is never
+necessary; reallocation is handled automatically by GMP when needed.
+
+While @var{n} defines the initial space, @var{x} will grow automatically in the
+normal way, if necessary, for subsequent values stored.  @code{mpz_init2} makes
+it possible to avoid such reallocations if a maximum size is known in advance.
+
+In preparation for an operation, GMP often allocates one limb more than
+ultimately needed.  To make sure GMP will not perform reallocation for
+@var{x}, you need to add the number of bits in @code{mp_limb_t} to @var{n}.
+@end deftypefun
+
+@deftypefun void mpz_clear (mpz_t @var{x})
+Free the space occupied by @var{x}.  Call this function for all @code{mpz_t}
+variables when you are done with them.
+@end deftypefun
+
+@deftypefun void mpz_clears (mpz_t @var{x}, ...)
+Free the space occupied by a NULL-terminated list of @code{mpz_t} variables.
+@end deftypefun
+
+@deftypefun void mpz_realloc2 (mpz_t @var{x}, mp_bitcnt_t @var{n})
+Change the space allocated for @var{x} to @var{n} bits.  The value in @var{x}
+is preserved if it fits, or is set to 0 if not.
+
+Calling this function is never necessary; reallocation is handled automatically
+by GMP when needed.  But this function can be used to increase the space for a
+variable in order to avoid repeated automatic reallocations, or to decrease it
+to give memory back to the heap.

+
+For convenience, GMP provides a parallel series of initialize-and-set functions
+which initialize the output and then store the value there.  These functions'
+names have the form @code{mpz_init_set@dots{}}
+
+Here is an example of using one:
+
+@example
+@{
+  mpz_t pie;
+  mpz_init_set_str (pie, "3141592653589793238462643383279502884", 10);
+  @dots{}
+  mpz_sub (pie, @dots{});
+  @dots{}
+  mpz_clear (pie);
+@}
+@end example
+
+@noindent
+Once the integer has been initialized by any of the @code{mpz_init_set@dots{}}
+functions, it can be used as the source or destination operand for the ordinary
+integer functions.  Don't use an initialize-and-set function on a variable
+already initialized!

+@end deftypefun
+
+@deftypefun int mpz_init_set_str (mpz_t @var{rop}, const char *@var{str}, int @var{base})
+Initialize @var{rop} and set its value like @code{mpz_set_str} (see its

+
+If the string is a correct base @var{base} number, the function returns 0;

+
+This section describes functions for converting GMP integers to standard C
+types.  Functions for converting @emph{to} GMP integers are described in
+@ref{Assigning Integers} and @ref{I/O of Integers}.
+
+@deftypefun {unsigned long int} mpz_get_ui (const mpz_t @var{op})
+Return the value of @var{op} as an @code{unsigned long}.
+
+If @var{op} is too big to fit an @code{unsigned long} then just the least
+significant bits that do fit are returned.  The sign of @var{op} is ignored,
+only the absolute value is used.
+@end deftypefun
+
+@deftypefun {signed long int} mpz_get_si (const mpz_t @var{op})
+If @var{op} fits into a @code{signed long int} return the value of @var{op}.
+Otherwise return the least significant part of @var{op}, with the same sign
+as @var{op}.
+
+If @var{op} is too big to fit in a @code{signed long int}, the returned
+result is probably not very useful.  To find out if the value will fit, use
+the function @code{mpz_fits_slong_p}.
+@end deftypefun
+
+@deftypefun double mpz_get_d (const mpz_t @var{op})
+Convert @var{op} to a @code{double}, truncating if necessary (i.e.@: rounding
+towards zero).
+
+If the exponent from the conversion is too big, the result is system
+dependent.  An infinity is returned where available.  A hardware overflow trap
+may or may not occur.
+@end deftypefun
+
+@deftypefun double mpz_get_d_2exp (signed long int *@var{exp}, const mpz_t @var{op})
+Convert @var{op} to a @code{double}, truncating if necessary (i.e.@: rounding
+towards zero), and returning the exponent separately.
+
+The return value is in the range @math{0.5@le{}@GMPabs{@var{d}}<1} and the
+exponent is stored to @code{*@var{exp}}.  @m{@var{d} * 2^{exp}, @var{d} *
+2^@var{exp}} is the (truncated) @var{op} value.  If @var{op} is zero, the
+return is @math{0.0} and 0 is stored to @code{*@var{exp}}.
+
+@cindex @code{frexp}
+This is similar to the standard C @code{frexp} function (@pxref{Normalization
+Functions,,, libc, The GNU C Library Reference Manual}).
+@end deftypefun
+
+@deftypefun {char *} mpz_get_str (char *@var{str}, int @var{base}, const mpz_t @var{op})
+Convert @var{op} to a string of digits in base @var{base}.  The base argument
+may vary from 2 to 62 or from @minus{}2 to @minus{}36.
+
+For @var{base} in the range 2..36, digits and lower-case letters are used; for
+@minus{}2..@minus{}36, digits and upper-case letters are used; for 37..62,
+digits, upper-case letters, and lower-case letters (in that significance order)
+are used.
+
+If @var{str} is @code{NULL}, the result string is allocated using the current
+allocation function (@pxref{Custom Allocation}).  The block will be
+@code{strlen(str)+1} bytes, that being exactly enough for the string and
+null-terminator.
+
+If @var{str} is not @code{NULL}, it should point to a block of storage large
+enough for the result, that being @code{mpz_sizeinbase (@var{op}, @var{base})
++ 2}.  The two extra bytes are for a possible minus sign, and the
+null-terminator.
+
+A pointer to the result string is returned, being either the allocated block,
+or the given @var{str}.

+
+@sp 1
+Divide @var{n} by @var{d}, forming a quotient @var{q} and/or remainder
+@var{r}.  For the @code{2exp} functions, @m{@var{d}=2^b, @var{d}=2^@var{b}}.
+The rounding is in three styles, each suiting different applications.
+
+@itemize @bullet
+@item
+@code{cdiv} rounds @var{q} up towards @m{+\infty, +infinity}, and @var{r} will
+have the opposite sign to @var{d}.  The @code{c} stands for ``ceil''.
+
+@item
+@code{fdiv} rounds @var{q} down towards @m{-\infty, @minus{}infinity}, and
+@var{r} will have the same sign as @var{d}.  The @code{f} stands for
+``floor''.
+
+@item
+@code{tdiv} rounds @var{q} towards zero, and @var{r} will have the same sign
+as @var{n}.  The @code{t} stands for ``truncate''.
+@end itemize
+
+In all cases @var{q} and @var{r} will satisfy
+@m{@var{n}=@var{q}@var{d}+@var{r}, @var{n}=@var{q}*@var{d}+@var{r}}, and
+@var{r} will satisfy @math{0@le{}@GMPabs{@var{r}}<@GMPabs{@var{d}}}.
+
+The @code{q} functions calculate only the quotient, the @code{r} functions
+only the remainder, and the @code{qr} functions calculate both.  Note that for
+@code{qr} the same variable cannot be passed for both @var{q} and @var{r}, or
+results will be unpredictable.
+
+For the @code{ui} variants the return value is the remainder, and in fact
+returning the remainder is all the @code{div_ui} functions do.  For
+@code{tdiv} and @code{cdiv} the remainder can be negative, so for those the
+return value is the absolute value of the remainder.
+
+For the @code{2exp} variants the divisor is @m{2^b,2^@var{b}}.  These
+functions are implemented as right shifts and bit masks, but of course they
+round the same as the other functions.
+
+For positive @var{n} both @code{mpz_fdiv_q_2exp} and @code{mpz_tdiv_q_2exp}
+are simple bitwise right shifts.  For negative @var{n}, @code{mpz_fdiv_q_2exp}
+is effectively an arithmetic right shift treating @var{n} as twos complement
+the same as the bitwise logical functions do, whereas @code{mpz_tdiv_q_2exp}
+effectively treats @var{n} as sign and magnitude.

+
+@code{mpz_t} variables can be converted to and from arbitrary words of binary
+data with the following functions.
+
+@deftypefun void mpz_import (mpz_t @var{rop}, size_t @var{count}, int @var{order}, size_t @var{size}, int @var{endian}, size_t @var{nails}, const void *@var{op})
+@cindex Integer import
+@cindex Import
+Set @var{rop} from an array of word data at @var{op}.
+
+The parameters specify the format of the data.  @var{count} many words are
+read, each @var{size} bytes.  @var{order} can be 1 for most significant word
+first or -1 for least significant first.  Within each word @var{endian} can be
+1 for most significant byte first, -1 for least significant first, or 0 for
+the native endianness of the host CPU@.  The most significant @var{nails} bits
+of each word are skipped, this can be 0 to use the full words.
+
+There is no sign taken from the data, @var{rop} will simply be a positive
+integer.  An application can handle any sign itself, and apply it for instance
+with @code{mpz_neg}.
+
+There are no data alignment restrictions on @var{op}, any address is allowed.
+
+Here's an example converting an array of @code{unsigned long} data, most
+significant element first, and host byte order within each value.
+
+@example
+unsigned long  a[20];
+/* Initialize @var{z} and @var{a} */
+mpz_import (z, 20, 1, sizeof(a[0]), 0, 0, a);
+@end example
+
+This example assumes the full @code{sizeof} bytes are used for data in the
+given type, which is usually true, and certainly true for @code{unsigned long}
+everywhere we know of.  However on Cray vector systems it may be noted that
+@code{short} and @code{int} are always stored in 8 bytes (and with
+@code{sizeof} indicating that) but use only 32 or 46 bits.  The @var{nails}
+feature can account for this, by passing for instance
+@code{8*sizeof(int)-INT_BIT}.
+@end deftypefun
+
+@deftypefun {void *} mpz_export (void *@var{rop}, size_t *@var{countp}, int @var{order}, size_t @var{size}, int @var{endian}, size_t @var{nails}, const mpz_t @var{op})
+@cindex Integer export
+@cindex Export
+Fill @var{rop} with word data from @var{op}.
+
+The parameters specify the format of the data produced.  Each word will be
+@var{size} bytes and @var{order} can be 1 for most significant word first or
+-1 for least significant first.  Within each word @var{endian} can be 1 for
+most significant byte first, -1 for least significant first, or 0 for the
+native endianness of the host CPU@.  The most significant @var{nails} bits of
+each word are unused and set to zero, this can be 0 to produce full words.
+
+The number of words produced is written to @code{*@var{countp}}, or
+@var{countp} can be @code{NULL} to discard the count.  @var{rop} must have
+enough space for the data, or if @var{rop} is @code{NULL} then a result array
+of the necessary size is allocated using the current GMP allocation function
+(@pxref{Custom Allocation}).  In either case the return value is the
+destination used, either @var{rop} or the allocated block.
+
+If @var{op} is non-zero then the most significant word produced will be
+non-zero.  If @var{op} is zero then the count returned will be zero and
+nothing written to @var{rop}.  If @var{rop} is @code{NULL} in this case, no
+block is allocated, just @code{NULL} is returned.
+
+The sign of @var{op} is ignored, just the absolute value is exported.  An
+application can use @code{mpz_sgn} to get the sign and handle it as desired.
+(@pxref{Integer Comparisons})
+
+There are no data alignment restrictions on @var{rop}, any address is allowed.
+
+When an application is allocating space itself the required size can be
+determined with a calculation like the following.  Since @code{mpz_sizeinbase}
+always returns at least 1, @code{count} here will be at least one, which
+avoids any portability problems with @code{malloc(0)}, though if @code{z} is
+zero no space at all is actually needed (or written).
+
+@example
+numb = 8*size - nail;
+count = (mpz_sizeinbase (z, 2) + numb-1) / numb;
+p = malloc (count * size);

+This chapter describes the GMP functions for performing arithmetic on rational
+numbers.  These functions start with the prefix @code{mpq_}.
+
+Rational numbers are stored in objects of type @code{mpq_t}.
+
+All rational arithmetic functions assume operands have a canonical form, and
+canonicalize their result.  The canonical form means that the denominator and
+the numerator have no common factors, and that the denominator is positive.
+Zero has the unique representation 0/1.
+
+Pure assignment functions do not canonicalize the assigned variable.  It is
+the responsibility of the user to canonicalize the assigned variable before
+any arithmetic operations are performed on that variable.
+
+@deftypefun void mpq_canonicalize (mpq_t @var{op})

+The set of @code{mpq} functions is quite small.  In particular, there are few
+functions for either input or output.  The following functions give direct
+access to the numerator and denominator of an @code{mpq_t}.
+
+Note that if an assignment to the numerator and/or denominator could take an
+@code{mpq_t} out of the canonical form described at the start of this chapter
+(@pxref{Rational Number Functions}) then @code{mpq_canonicalize} must be
+called before any other @code{mpq} functions are applied to that @code{mpq_t}.
+
+@deftypefn Macro mpz_t mpq_numref (const mpq_t @var{op})
+@deftypefnx Macro mpz_t mpq_denref (const mpq_t @var{op})

+Functions that perform input from a stdio stream, and functions that output to
+a stdio stream, of @code{mpq} numbers.  Passing a @code{NULL} pointer for a
+@var{stream} argument to any of these functions will make them read from
+@code{stdin} and write to @code{stdout}, respectively.
+
+When using any of these functions, it is a good idea to include @file{stdio.h}
+before @file{gmp.h}, since that will allow @file{gmp.h} to define prototypes
+for these functions.
+
+See also @ref{Formatted Output} and @ref{Formatted Input}.
+
+@deftypefun size_t mpq_out_str (FILE *@var{stream}, int @var{base}, const mpq_t @var{op})
+Output @var{op} on stdio stream @var{stream}, as a string of digits in base
+@var{base}.  The base argument may vary from 2 to 62 or from @minus{}2 to
+@minus{}36. Output is in the form
+@samp{num/den} or if the denominator is 1 then just @samp{num}.
+
+For @var{base} in the range 2..36, digits and lower-case letters are used; for
+@minus{}2..@minus{}36, digits and upper-case letters are used; for 37..62,
+digits, upper-case letters, and lower-case letters (in that significance order)
+are used.

+@end deftypefun
+
+@deftypefun size_t mpq_inp_str (mpq_t @var{rop}, FILE *@var{stream}, int @var{base})
+Read a string of digits from @var{stream} and convert them to a rational in
+@var{rop}.  Any initial white-space characters are read and discarded.  Return
+the number of characters read (including white space), or 0 if a rational
+could not be read.
+
+The input can be a fraction like @samp{17/63} or just an integer like
+@samp{123}.  Reading stops at the first character not in this form, and white
+space is not permitted within the string.  If the input might not be in
+canonical form, then @code{mpq_canonicalize} must be called (@pxref{Rational
+Number Functions}).
+
+The @var{base} can be between 2 and 62, or can be 0 in which case the leading
+characters of the string determine the base, @samp{0x} or @samp{0X} for
+hexadecimal, @code{0b} and @code{0B} for binary, @samp{0} for octal, or
+decimal otherwise.  The leading characters
+are examined separately for the numerator and denominator of a fraction, so
+for instance @samp{0x10/11} is @math{16/11}, whereas @samp{0x10/0x11} is
+@math{16/17}.

+@chapter Floating-point Functions
+@cindex Floating-point functions
+@cindex Float functions
+@cindex User-defined precision
+@cindex Precision of floats
+
+GMP floating point numbers are stored in objects of type @code{mpf_t} and
+functions operating on them have an @code{mpf_} prefix.
+
+The mantissa of each float has a user-selectable precision, in practice only
+limited by available memory.  Each variable has its own precision, and that can
+be increased or decreased at any time.  This selectable precision is a minimum
+value, GMP rounds it up to a whole limb.
+
+The accuracy of a calculation is determined by the priorly set precision of the
+destination variable and the numeric values of the input variables.  Input
+variables' set precisions do not affect calculations (except indirectly as
+their values might have been affected when they were assigned).
+
+The exponent of each float has fixed precision, one machine word on most
+systems.  In the current implementation the exponent is a count of limbs, so
+for example on a 32-bit system this means a range of roughly
+@math{2^@W{-68719476768}} to @math{2^@W{68719476736}}, or on a 64-bit system
+this will be much greater.  Note however that @code{mpf_get_str} can only
+return an exponent which fits an @code{mp_exp_t} and currently
+@code{mpf_set_str} doesn't accept exponents bigger than a @code{long}.
+
+Each variable keeps track of the mantissa data actually in use.  This means
+that if a float is exactly represented in only a few bits then only those bits
+will be used in a calculation, even if the variable's selected precision is
+high.  This is a performance optimization; it does not affect the numeric
+results.
+
+Internally, GMP sometimes calculates with higher precision than that of the
+destination variable in order to limit errors.  Final results are always
+truncated to the destination variable's precision.
+
+The mantissa is stored in binary.  One consequence of this is that decimal
+fractions like @math{0.1} cannot be represented exactly.  The same is true of
+plain IEEE @code{double} floats.  This makes both highly unsuitable for
+calculations involving money or other values that should be exact decimal
+fractions.  (Suitably scaled integers, or perhaps rationals, are better
+choices.)
+
+The @code{mpf} functions and variables have no special notion of infinity or
+not-a-number, and applications must take care not to overflow the exponent or
+results will be unpredictable.
+
+Note that the @code{mpf} functions are @emph{not} intended as a smooth
+extension to IEEE P754 arithmetic.  In particular results obtained on one
+computer often differ from the results on a computer with a different word
+size.
+
+New projects should consider using the GMP extension library MPFR
+(@url{http://mpfr.org}) instead.  MPFR provides well-defined precision and
+accurate rounding, and thereby naturally extends IEEE P754.

+purpose.
+
+@deftypefun void mpf_init (mpf_t @var{x})
+Initialize @var{x} to 0.  Normally, a variable should be initialized once only

+@end deftypefun

+Here is an example on how to initialize floating-point variables:

+@{
+  mpf_t x, y;

+  @dots{}
+  /* Unless the program is about to exit, do ... */
+  mpf_clear (x);
+  mpf_clear (y);
+@}
+@end example
+
+The following three functions are useful for changing the precision during a
+calculation.  A typical use would be for adjusting the precision gradually in
+iterative algorithms like Newton-Raphson, making the computation precision
+closely match the actual accurate part of the numbers.
+
+@deftypefun {mp_bitcnt_t} mpf_get_prec (const mpf_t @var{op})
+Return the current precision of @var{op}, in bits.
+@end deftypefun
+
+@deftypefun void mpf_set_prec (mpf_t @var{rop}, mp_bitcnt_t @var{prec})
+Set the precision of @var{rop} to be @strong{at least} @var{prec} bits.  The
+value in @var{rop} will be truncated to the new precision.
+
+This function requires a call to @code{realloc}, and so should not be used in
+a tight loop.
+@end deftypefun
+
+@deftypefun void mpf_set_prec_raw (mpf_t @var{rop}, mp_bitcnt_t @var{prec})
+Set the precision of @var{rop} to be @strong{at least} @var{prec} bits,
+without changing the memory allocated.
+
+@var{prec} must be no more than the allocated precision for @var{rop}, that
+being the precision when @var{rop} was initialized, or in the most recent
+@code{mpf_set_prec}.
+
+The value in @var{rop} is unchanged, and in particular if it had a higher
+precision than @var{prec} it will retain that higher precision.  New values
+written to @var{rop} will use the new @var{prec}.
+
+Before calling @code{mpf_clear} or the full @code{mpf_set_prec}, another
+@code{mpf_set_prec_raw} call must be made to restore @var{rop} to its original
+allocated precision.  Failing to do so will have unpredictable results.
+
+@code{mpf_get_prec} can be used before @code{mpf_set_prec_raw} to get the
+original allocated precision.  After @code{mpf_set_prec_raw} it reflects the
+@var{prec} value set.
+
+@code{mpf_set_prec_raw} is an efficient way to use an @code{mpf_t} variable at
+different precisions during a calculation, perhaps to gradually increase
+precision in an iteration, or just to use various different precisions for
+different purposes during a calculation.

+Set the value of @var{rop} from the string in @var{str}.  The string is of the
+form @samp{M@@N} or, if the base is 10 or less, alternatively @samp{MeN}.
+@samp{M} is the mantissa and @samp{N} is the exponent.  The mantissa is always
+in the specified base.  The exponent is either in the specified base or, if
+@var{base} is negative, in decimal.  The decimal point expected is taken from
+the current locale, on systems providing @code{localeconv}.
+
+The argument @var{base} may be in the ranges 2 to 62, or @minus{}62 to
+@minus{}2.  Negative values are used to specify that the exponent is in
+decimal.
+
+For bases up to 36, case is ignored; upper-case and lower-case letters have
+the same value; for bases 37 to 62, upper-case letter represent the usual
+10..35 while lower-case letter represent 36..61.
+
+Unlike the corresponding @code{mpz} function, the base will not be determined
+from the leading characters of the string if @var{base} is 0.  This is so that
+numbers like @samp{0.23} are not interpreted as octal.
+
+White space is allowed in the string, and is simply ignored.  [This is not
+really true; white-space is ignored in the beginning of the string and within
+the mantissa, but not in other places, such as after a minus sign or in the
+exponent.  We are considering changing the definition of this function, making

+sense.  Please tell us your opinion about this change.  Do you really want it
+to accept @nicode{"3 14"} as meaning 314 as it does now?]

+
+If @var{str} is not @code{NULL}, it should point to a block of

+Functions that perform input from a stdio stream, and functions that output to
+a stdio stream, of @code{mpf} numbers.  Passing a @code{NULL} pointer for a
+@var{stream} argument to any of these functions will make them read from
+@code{stdin} and write to @code{stdout}, respectively.
+
+When using any of these functions, it is a good idea to include @file{stdio.h}
+before @file{gmp.h}, since that will allow @file{gmp.h} to define prototypes
+for these functions.

+Print @var{op} to @var{stream}, as a string of digits.  Return the number of
+bytes written, or if an error occurred, return 0.
+
+The mantissa is prefixed with an @samp{0.} and is in the given @var{base},
+which may vary from 2 to 62 or from @minus{}2 to @minus{}36.  An exponent is
+then printed, separated by an @samp{e}, or if the base is greater than 10 then
+by an @samp{@@}.  The exponent is always in decimal.  The decimal point follows
+the current locale, on systems providing @code{localeconv}.
+
+For @var{base} in the range 2..36, digits and lower-case letters are used; for
+@minus{}2..@minus{}36, digits and upper-case letters are used; for 37..62,
+digits, upper-case letters, and lower-case letters (in that significance order)
+are used.
+
+Up to @var{n_digits} will be printed from the mantissa, except that no more
+digits than are accurately representable by @var{op} will be printed.
+@var{n_digits} can be 0 to select that accurate maximum.

+less, alternatively @samp{MeN}.  @samp{M} is the mantissa and @samp{N} is the
+exponent.  The mantissa is always in the specified base.  The exponent is
+either in the specified base or, if @var{base} is negative, in decimal.  The
+decimal point expected is taken from the current locale, on systems providing

+
+The argument @var{base} may be in the ranges 2 to 36, or @minus{}36 to

+@chapter Low-level Functions
+@cindex Low-level functions
+
+This chapter describes low-level GMP functions, used to implement the
+high-level GMP functions, but also intended for time-critical user code.
+
+These functions start with the prefix @code{mpn_}.
+
+@c 1. Some of these function clobber input operands.
+@c
+
+The @code{mpn} functions are designed to be as fast as possible, @strong{not}
+to provide a coherent calling interface.  The different functions have somewhat
+similar interfaces, but there are variations that make them hard to use.  These
+functions do as little as possible apart from the real multiple precision
+computation, so that no time is spent on things that not all callers need.
+
+A source operand is specified by a pointer to the least significant limb and a
+limb count.  A destination operand is specified by just a pointer.  It is the
+responsibility of the caller to ensure that the destination has enough space
+for storing the result.
+
+With this way of specifying operands, it is possible to perform computations on
+subranges of an argument, and store the result into a subrange of a
+destination.
+
+A common requirement for all functions is that each source area needs at least
+one limb.  No size argument may be zero.  Unless otherwise stated, in-place
+operations are allowed where source and destination are the same, but not where
+they only partly overlap.
+
+The @code{mpn} functions are the base for the implementation of the
+@code{mpz_}, @code{mpf_}, and @code{mpq_} functions.
+
+This example adds the number beginning at @var{s1p} and the number beginning at
+@var{s2p} and writes the sum at @var{destp}.  All areas have @var{n} limbs.
+
+@example
+cy = mpn_add_n (destp, s1p, s2p, n)
+@end example
+
+It should be noted that the @code{mpn} functions make no attempt to identify
+high or low zero limbs on their operands, or other special forms.  On random
+data such cases will be unlikely and it'd be wasteful for every function to
+check every time.  An application knowing something about its data can take
+steps to trim or perhaps split its calculations.
+@c
+@c  For reference, within gmp mpz_t operands never have high zero limbs, and
+@c  we rate low zero limbs as unlikely too (or something an application should
+@c  handle).  This is a prime motivation for not stripping zero limbs in say
+@c  mpn_mul_n etc.
+@c
+@c  Other applications doing variable-length calculations will quite likely do
+@c  something similar to mpz.  And even if not then it's highly likely zero
+@c  limb stripping can be done at just a few judicious points, which will be
+@c  more efficient than having lots of mpn functions checking every time.
+
+@sp 1

+In the notation used below, a source operand is identified by the pointer to
+the least significant limb, and the limb count in braces.  For example,
+@{@var{s1p}, @var{s1n}@}.

+least significant limbs of the result to @var{rp}.  Return carry, either 0 or
+1.
+
+This is the lowest-level function for addition.  It is the preferred function
+for addition, since it is written in assembly for most CPUs.  For addition of

+The source @math{a}, result @math{q}, size @math{n}, initial carry @math{i},

+@section Low-level functions for cryptography
+@cindex Low-level functions for cryptography
+@cindex Cryptography functions, low-level
+
+The functions prefixed with @code{mpn_sec_} and @code{mpn_cnd_} are designed to
+perform the exact same low-level operations and have the same cache access
+patterns for any two same-size arguments, assuming that function arguments are
+placed at the same position and that the machine state is identical upon
+function entry.  These functions are intended for cryptographic purposes, where
+resilience to side-channel attacks is desired.
+
+These functions are less efficient than their ``leaky'' counterparts; their
+performance for operands of the sizes typically used for cryptographic
+applications is between 15% and 100% worse.  For larger operands, these
+functions might be inadequate, since they rely on asymptotically elementary
+algorithms.
+
+These functions do not make any explicit allocations.  Those of these functions
+that need scratch space accept a scratch space operand.  This convention allows
+callers to keep sensitive data in designated memory areas.  Note however that
+compilers may choose to spill scalar values used within these functions to
+their stack frame and that such scalars may contain sensitive data.
+
+In addition to these specially crafted functions, the following @code{mpn}
+functions are naturally side-channel resistant: @code{mpn_add_n},
+@code{mpn_sub_n}, @code{mpn_lshift}, @code{mpn_rshift}, @code{mpn_zero},
+@code{mpn_copyi}, @code{mpn_copyd}, @code{mpn_com}, and the logical function
+(@code{mpn_and_n}, etc).
+
+There are some exceptions from the side-channel resilience: (1) Some assembly
+implementations of @code{mpn_lshift} identify shift-by-one as a special case.
+This is a problem iff the shift count is a function of sensitive data.  (2)
+Alpha ev6 and Pentium4 using 64-bit limbs have leaky @code{mpn_add_n} and
+@code{mpn_sub_n}.  (3) Alpha ev6 has a leaky @code{mpn_mul_1} which also makes
+@code{mpn_sec_mul} on those systems unsafe.

+These functions do conditional addition and subtraction.  If @var{cnd} is
+non-zero, they produce the same result as a regular @code{mpn_add_n} or
+@code{mpn_sub_n}, and if @var{cnd} is zero, they copy @{@var{s1p},@var{n}@} to
+the result area and return zero.  The functions are designed to have timing and
+memory access patterns depending only on size and location of the data areas,
+but independent of the condition @var{cnd}.  Like for @code{mpn_add_n} and

+

+@section Nails
+@cindex Nails
+
+@strong{Everything in this section is highly experimental and may disappear or
+be subject to incompatible changes in a future version of GMP.}
+
+Nails are an experimental feature whereby a few bits are left unused at the
+top of each @code{mp_limb_t}.  This can significantly improve carry handling
+on some processors.
+
+All the @code{mpn} functions accepting limb data will expect the nail bits to
+be zero on entry, and will return data with the nails similarly all zero.
+This applies both to limb vectors and to single limb arguments.
+
+Nails can be enabled by configuring with @samp{--enable-nails}.  By default
+the number of bits will be chosen according to what suits the host processor,
+but a particular number can be selected with @samp{--enable-nails=N}.
+
+At the mpn level, a nail build is neither source nor binary compatible with a
+non-nail build, strictly speaking.  But programs acting on limbs only through
+the mpn functions are likely to work equally well with either build, and
+judicious use of the definitions below should make any program compatible with
+either build, at the source level.
+
+For the higher level routines, meaning @code{mpz} etc, a nail build should be
+fully source and binary compatible with a non-nail build.
+
+@defmac GMP_NAIL_BITS
+@defmacx GMP_NUMB_BITS
+@defmacx GMP_LIMB_BITS
+@code{GMP_NAIL_BITS} is the number of nail bits, or 0 when nails are not in
+use.  @code{GMP_NUMB_BITS} is the number of data bits in a limb.
+@code{GMP_LIMB_BITS} is the total number of bits in an @code{mp_limb_t}.  In
+all cases
+
+@example
+GMP_LIMB_BITS == GMP_NAIL_BITS + GMP_NUMB_BITS
+@end example
+@end defmac
+
+@defmac GMP_NAIL_MASK
+@defmacx GMP_NUMB_MASK
+Bit masks for the nail and number parts of a limb.  @code{GMP_NAIL_MASK} is 0
+when nails are not in use.
+
+@code{GMP_NAIL_MASK} is not often needed, since the nail part can be obtained
+with @code{x >> GMP_NUMB_BITS}, and that means one less large constant, which
+can help various RISC chips.
+@end defmac
+
+@defmac GMP_NUMB_MAX
+The maximum value that can be stored in the number part of a limb.  This is
+the same as @code{GMP_NUMB_MASK}, but can be used for clarity when doing
+comparisons rather than bit-wise operations.
+@end defmac
+
+The term ``nails'' comes from finger or toe nails, which are at the ends of a
+limb (arm or leg).  ``numb'' is short for number, but is also how the
+developers felt after trying for a long time to come up with sensible names
+for these things.
+
+In the future (the distant future most likely) a non-zero nail might be
+permitted, giving non-unique representations for numbers in a limb vector.
+This would help vector processors since carries would only ever need to
+propagate one or two limbs.

+@cindex Random number functions
+
+Sequences of pseudo-random numbers in GMP are generated using a variable of
+type @code{gmp_randstate_t}, which holds an algorithm selection and a current
+state.  Such a variable must be initialized by a call to one of the
+@code{gmp_randinit} functions, and can be seeded with one of the
+@code{gmp_randseed} functions.
+
+The functions actually generating random numbers are described in @ref{Integer
+Random Numbers}, and @ref{Miscellaneous Float Functions}.
+
+The older style random number functions don't accept a @code{gmp_randstate_t}
+parameter but instead share a global variable of that type.  They use a
+default algorithm and are currently not seeded (though perhaps that will
+change in the future).  The new functions accepting a @code{gmp_randstate_t}
+are recommended for applications that care about randomness.

+
+Traditionally the system time has been used to seed, but care needs to be
+taken with this.  If an application seeds often and the resolution of the
+system clock is low, then the same sequence of numbers might be repeated.
+Also, the system time is quite easy to guess, so if unpredictability is

+@code{gmp_printf} and friends accept format strings similar to the standard C
+@code{printf} (@pxref{Formatted Output,, Formatted Output, libc, The GNU C
+Library Reference Manual}).  A format specification is of the form
+
+@example
+% [flags] [width] [.[precision]] [type] conv
+@end example
+
+GMP adds types @samp{Z}, @samp{Q} and @samp{F} for @code{mpz_t}, @code{mpq_t}
+and @code{mpf_t} respectively, @samp{M} for @code{mp_limb_t}, and @samp{N} for
+an @code{mp_limb_t} array.  @samp{Z}, @samp{Q}, @samp{M} and @samp{N} behave
+like integers.  @samp{Q} will print a @samp{/} and a denominator, if needed.
+@samp{F} behaves like a float.  For example,
+
+@example
+mpz_t z;
+gmp_printf ("%s is an mpz %Zd\n", "here", z);
+
+mpq_t q;
+gmp_printf ("a hex rational: %#40Qx\n", q);
+
+mpf_t f;
+int   n;
+gmp_printf ("fixed point mpf %.*Ff with %d digits\n", n, f, n);
+
+mp_limb_t l;
+gmp_printf ("limb %Mu\n", l);
+
+const mp_limb_t *ptr;
+mp_size_t       size;
+gmp_printf ("limb array %Nx\n", ptr, size);
+@end example
+
+For @samp{N} the limbs are expected least significant first, as per the
+@code{mpn} functions (@pxref{Low-level Functions}).  A negative size can be
+given to print the value as a negative.
+
+All the standard C @code{printf} types behave the same as the C library
+@code{printf}, and can be freely intermixed with the GMP extensions.  In the
+current implementation the standard parts of the format string are simply
+handed to @code{printf} and only the GMP extensions handled directly.
+
+The flags accepted are as follows.  GLIBC style @nisamp{'} is only for the
+standard C types (not the GMP types), and only if the C library supports it.

+
+@samp{o}, @samp{x} and @samp{X} are unsigned for the standard C types, but for
+types @samp{Z}, @samp{Q} and @samp{N} they are signed.  @samp{u} is not
+meaningful for @samp{Z}, @samp{Q} and @samp{N}.
+
+@samp{M} is a proxy for the C library @samp{l} or @samp{L}, according to the
+size of @code{mp_limb_t}.  Unsigned conversions will be usual, but a signed
+conversion can be used and will interpret the value as a twos complement
+negative.
+
+@samp{n} can be used with any type, even the GMP types.
+
+Other types or conversions that might be accepted by the C library
+@code{printf} cannot be used through @code{gmp_printf}, this includes for
+instance extensions registered with GLIBC @code{register_printf_function}.
+Also currently there's no support for POSIX @samp{$} style numbered arguments
+(perhaps this will be added in the future).
+
+The precision field has its usual meaning for integer @samp{Z} and float
+@samp{F} types, but is currently undefined for @samp{Q} and should not be used
+with that.
+
+@code{mpf_t} conversions only ever generate as many digits as can be
+accurately represented by the operand, the same as @code{mpf_get_str} does.
+Zeros will be used if necessary to pad to the requested precision.  This
+happens even for an @samp{f} conversion of an @code{mpf_t} which is an
+integer, for instance @math{2^@W{1024}} in an @code{mpf_t} of 128 bits
+precision will only produce about 40 digits, then pad with zeros to the
+decimal point.  An empty precision field like @samp{%.Fe} or @samp{%.Ff} can
+be used to specifically request just the significant digits.  Without any dot
+and thus no precision field, a precision value of 6 will be used.  Note that
+these rules mean that @samp{%Ff}, @samp{%.Ff}, and @samp{%.0Ff} will all be
+different.
+
+The decimal point character (or string) is taken from the current locale
+settings on systems which provide @code{localeconv} (@pxref{Locales,, Locales
+and Internationalization, libc, The GNU C Library Reference Manual}).  The C
+library will normally do the same for standard float output.
+
+The format string is only interpreted as plain @code{char}s, multibyte
+characters are not recognised.  Perhaps this will change in the future.

+Each of the following functions is similar to the corresponding C library
+function.  The basic @code{printf} forms take a variable argument list.  The
+@code{vprintf} forms take an argument pointer, see @ref{Variadic Functions,,
+Variadic Functions, libc, The GNU C Library Reference Manual}, or @samp{man 3
+va_start}.
+
+It should be emphasised that if a format string is invalid, or the arguments
+don't match what the format specifies, then the behaviour of any of these
+functions will be unpredictable.  GCC format string checking is not available,
+since it doesn't recognise the GMP extensions.
+
+The file based functions @code{gmp_printf} and @code{gmp_fprintf} will return
+@math{-1} to indicate a write error.  Output is not ``atomic'', so partial
+output may be produced if a write error occurs.  All the functions can return
+@math{-1} if the C library @code{printf} variant in use returns @math{-1}, but
+this shouldn't normally occur.
+
+@deftypefun int gmp_printf (const char *@var{fmt}, @dots{})

+@deftypefun int gmp_fprintf (FILE *@var{fp}, const char *@var{fmt}, @dots{})

+Form a null-terminated string in @var{buf}.  Return the number of characters
+written, excluding the terminating null.
+
+No overlap is permitted between the space at @var{buf} and the string
+@var{fmt}.
+
+These functions are not recommended, since there's no protection against
+exceeding the space available at @var{buf}.

+@deftypefunx int gmp_vsnprintf (char *@var{buf}, size_t @var{size}, const char *@var{fmt}, va_list @var{ap})
+Form a null-terminated string in @var{buf}.  No more than @var{size} bytes
+will be written.  To get the full output, @var{size} must be enough for the
+string and null-terminator.
+
+The return value is the total number of characters which ought to have been
+produced, excluding the terminating null.  If @math{@var{retval} @ge{}
+@var{size}} then the actual output has been truncated to the first
+@math{@var{size}-1} characters, and a null appended.
+
+No overlap is permitted between the region @{@var{buf},@var{size}@} and the
+@var{fmt} string.
+
+Notice the return value is in ISO C99 @code{snprintf} style.  This is so even
+if the C library @code{vsnprintf} is the older GLIBC 2.0.x style.

+Form a null-terminated string in a block of memory obtained from the current
+memory allocation function (@pxref{Custom Allocation}).  The block will be the
+size of the string and null-terminator.  The address of the block in stored to
+*@var{pp}.  The return value is the number of characters produced, excluding
+the null-terminator.
+
+Unlike the C library @code{asprintf}, @code{gmp_asprintf} doesn't return
+@math{-1} if there's no more memory available, it lets the current allocation

+@code{ostream operator<<} routines do.
+
+Output will be a fraction like @samp{5/9}, or if the denominator is 1 then

+
+In hex or octal, @var{op} is printed as a signed value, the same as for

+
+The decimal point follows the standard library float @code{operator<<}, which
+on recent systems means the @code{std::locale} imbued on @var{stream}.
+
+Hex and octal are supported, unlike the standard @code{operator<<} on
+@code{double}.  The mantissa will be in hex or octal, the exponent will be in
+decimal.  For hex the exponent delimiter is an @samp{@@}.  This is as per
+@code{mpf_out_str}.
+
+@code{ios::showbase} is supported, and will put a base on the mantissa, for
+example hex @samp{0x1.8} or @samp{0x0.8}, or octal @samp{01.4} or @samp{00.4}.
+This last form is slightly strange, but at least differentiates itself from

+
+@code{gmp_scanf} and friends accept format strings similar to the standard C
+@code{scanf} (@pxref{Formatted Input,, Formatted Input, libc, The GNU C
+Library Reference Manual}).  A format specification is of the form
+
+@example
+% [flags] [width] [type] conv
+@end example
+
+GMP adds types @samp{Z}, @samp{Q} and @samp{F} for @code{mpz_t}, @code{mpq_t}
+and @code{mpf_t} respectively.  @samp{Z} and @samp{Q} behave like integers.
+@samp{Q} will read a @samp{/} and a denominator, if present.  @samp{F} behaves
+like a float.
+
+GMP variables don't require an @code{&} when passed to @code{gmp_scanf}, since
+they're already ``call-by-reference''.  For example,
+
+@example
+/* to read say "a(5) = 1234" */
+int   n;
+mpz_t z;
+gmp_scanf ("a(%d) = %Zd\n", &n, z);
+
+mpq_t q1, q2;
+gmp_sscanf ("0377 + 0x10/0x11", "%Qi + %Qi", q1, q2);
+
+/* to read say "topleft (1.55,-2.66)" */
+mpf_t x, y;
+char  buf[32];
+gmp_scanf ("%31s (%Ff,%Ff)", buf, x, y);
+@end example
+
+All the standard C @code{scanf} types behave the same as in the C library
+@code{scanf}, and can be freely intermixed with the GMP extensions.  In the
+current implementation the standard parts of the format string are simply
+handed to @code{scanf} and only the GMP extensions handled directly.
+
+The flags accepted are as follows.  @samp{a} and @samp{'} will depend on

+read either fixed point or scientific format, and either upper or lower case
+@samp{e} for the exponent in scientific format.
+
+C99 style hex float format (@code{printf %a}, @pxref{Formatted Output
+Strings}) is always accepted for @code{mpf_t}, but for the standard float
+types it will depend on the C library.
+
+@samp{x} and @samp{X} are identical, both accept both upper and lower case
+hexadecimal.
+
+@samp{o}, @samp{u}, @samp{x} and @samp{X} all read positive or negative
+values.  For the standard C types these are described as ``unsigned''
+conversions, but that merely affects certain overflow handling, negatives are
+still allowed (per @code{strtoul}, @pxref{Parsing of Integers,, Parsing of
+Integers, libc, The GNU C Library Reference Manual}).  For GMP types there are
+no overflows, so @samp{d} and @samp{u} are identical.
+
+@samp{Q} type reads the numerator and (optional) denominator as given.  If the
+value might not be in canonical form then @code{mpq_canonicalize} must be
+called before using it in any calculations (@pxref{Rational Number
+Functions}).
+
+@samp{Qi} will read a base specification separately for the numerator and
+denominator.  For example @samp{0x10/11} would be 16/11, whereas
+@samp{0x10/0x11} would be 16/17.
+
+@samp{n} can be used with any of the types above, even the GMP types.
+@samp{*} to suppress assignment is allowed, though in that case it would do
+nothing at all.
+
+Other conversions or types that might be accepted by the C library
+@code{scanf} cannot be used through @code{gmp_scanf}.
+
+Whitespace is read and discarded before a field, except for @samp{c} and
+@samp{[} conversions.
+
+For float conversions, the decimal point character (or string) expected is
+taken from the current locale settings on systems which provide
+@code{localeconv} (@pxref{Locales,, Locales and Internationalization, libc,
+The GNU C Library Reference Manual}).  The C library will normally do the same
+for standard float input.
+
+The format string is only interpreted as plain @code{char}s, multibyte
+characters are not recognised.  Perhaps this will change in the future.

+
+The return value from each of these functions is the same as the standard C99
+@code{scanf}, namely the number of fields successfully parsed and stored.
+@samp{%n} fields and fields read but suppressed by @samp{*} don't count
+towards the return value.
+
+If end of input (or a file error) is reached before a character for a field or
+a literal, and if no previous non-suppressed fields have matched, then the
+return value is @code{EOF} instead of 0.  A whitespace character in the format
+string is only an optional match and doesn't induce an @code{EOF} in this
+fashion.  Leading whitespace read and discarded for a field don't count as
+characters for that field.
+
+For the GMP types, input parsing follows C99 rules, namely one character of
+lookahead is used and characters are read while they continue to meet the
+format requirements.  If this doesn't provide a complete number then the
+function terminates, with that field not stored nor counted towards the return
+value.  For instance with @code{mpf_t} an input @samp{1.23e-XYZ} would be read
+up to the @samp{X} and that character pushed back since it's not a digit.  The
+string @samp{1.23e-} would then be considered invalid since an @samp{e} must
+be followed by at least one digit.
+
+For the standard C types, in the current implementation GMP calls the C
+library @code{scanf} functions, which might have looser rules about what
+constitutes a valid input.
+
+Note that @code{gmp_sscanf} is the same as @code{gmp_fscanf} and only does one
+character of lookahead when parsing.  Although clearly it could look at its
+entire input, it is deliberately made identical to @code{gmp_fscanf}, the same
+way C99 @code{sscanf} is the same as @code{fscanf}.

+This chapter describes the C++ class based interface to GMP.
+
+All GMP C language types and functions can be used in C++ programs, since
+@file{gmp.h} has @code{extern "C"} qualifiers, but the class interface offers
+overloaded functions and operators which may be more convenient.
+
+Due to the implementation of this interface, a reasonably recent C++ compiler
+is required, one supporting namespaces, partial specialization of templates
+and member templates.
+

+and might be subject to incompatible changes if some unforeseen difficulty

+
+@noindent
+All the C++ classes and functions are available with
+
+@cindex @code{gmpxx.h}
+@example
+#include <gmpxx.h>
+@end example
+
+Programs should be linked with the @file{libgmpxx} and @file{libgmp}
+libraries.  For example,
+
+@example
+g++ mycxxprog.cc -lgmpxx -lgmp
+@end example
+
+@noindent
+The classes defined are
+
+@deftp Class mpz_class
+@deftpx Class mpq_class
+@deftpx Class mpf_class
+@end deftp
+
+The standard operators and various standard functions are overloaded to allow
+arithmetic with these classes.  For example,
+
+@example
+int
+main (void)
+@{
+  mpz_class a, b, c;
+
+  a = 1234;
+  b = "-5678";
+  c = a+b;
+  cout << "sum is " << c << "\n";
+  cout << "absolute value is " << abs(c) << "\n";
+
+  return 0;
+@}
+@end example
+
+An important feature of the implementation is that an expression like
+@code{a=b+c} results in a single call to the corresponding @code{mpz_add},
+without using a temporary for the @code{b+c} part.  Expressions which by their
+nature imply intermediate values, like @code{a=b*c+d*e}, still use temporaries
+though.
+
+The classes can be freely intermixed in expressions, as can the classes and
+the standard types @code{long}, @code{unsigned long} and @code{double}.
+Smaller types like @code{int} or @code{float} can also be intermixed, since
+C++ will promote them.
+
+Note that @code{bool} is not accepted directly, but must be explicitly cast to
+an @code{int} first.  This is because C++ will automatically convert any
+pointer to a @code{bool}, so if GMP accepted @code{bool} it would make all
+sorts of invalid class and pointer combinations compile but almost certainly
+not do anything sensible.
+
+Conversions back from the classes to standard C++ types aren't done
+automatically, instead member functions like @code{get_si} are provided (see
+the following sections for details).
+
+Also there are no automatic conversions from the classes to the corresponding
+GMP C types, instead a reference to the underlying C object can be obtained
+with the following functions,
+
+@deftypefun mpz_t mpz_class::get_mpz_t ()
+@deftypefunx mpq_t mpq_class::get_mpq_t ()
+@deftypefunx mpf_t mpf_class::get_mpf_t ()
+@end deftypefun
+
+These can be used to call a C function which doesn't have a C++ class
+interface.  For example to set @code{a} to the GCD of @code{b} and @code{c},
+
+@example
+mpz_class a, b, c;
+...
+mpz_gcd (a.get_mpz_t(), b.get_mpz_t(), c.get_mpz_t());
+@end example
+
+In the other direction, a class can be initialized from the corresponding GMP
+C type, or assigned to if an explicit constructor is used.  In both cases this
+makes a copy of the value, it doesn't create any sort of association.  For
+example,
+
+@example
+mpz_t z;
+// ... init and calculate z ...
+mpz_class x(z);
+mpz_class y;
+y = mpz_class (z);
+@end example
+
+There are no namespace setups in @file{gmpxx.h}, all types and functions are
+simply put into the global namespace.  This is what @file{gmp.h} has done in
+the past, and continues to do for compatibility.  The extras provided by
+@file{gmpxx.h} follow GMP naming conventions and are unlikely to clash with
+anything.

+@section C++ Interface Limitations
+
+@table @asis
+@item @code{mpq_class} and Templated Reading
+A generic piece of template code probably won't know that @code{mpq_class}
+requires a @code{canonicalize} call if inputs read with @code{operator>>}
+might be non-canonical.  This can lead to incorrect results.
+
+@code{operator>>} behaves as it does for reasons of efficiency.  A
+canonicalize can be quite time consuming on large operands, and is best
+avoided if it's not necessary.
+
+But this potential difficulty reduces the usefulness of @code{mpq_class}.
+Perhaps a mechanism to tell @code{operator>>} what to do will be adopted in
+the future, maybe a preprocessor define, a global flag, or an @code{ios} flag
+pressed into service.  Or maybe, at the risk of inconsistency, the
+@code{mpq_class} @code{operator>>} could canonicalize and leave @code{mpq_t}
+@code{operator>>} not doing so, for use on those occasions when that's
+acceptable.  Send feedback or alternate ideas to @email{gmp-bugs@@gmplib.org}.
+
+@item Subclassing
+Subclassing the GMP C++ classes works, but is not currently recommended.
+
+Expressions involving subclasses resolve correctly (or seem to), but in normal
+C++ fashion the subclass doesn't inherit constructors and assignments.
+There's many of those in the GMP classes, and a good way to reestablish them
+in a subclass is not yet provided.
+
+@item Templated Expressions
+A subtle difficulty exists when using expressions together with
+application-defined template functions.  Consider the following, with @code{T}
+intended to be some numeric type,
+
+@example
+template <class T>
+T fun (const T &, const T &);
+@end example
+
+@noindent
+When used with, say, plain @code{mpz_class} variables, it works fine: @code{T}
+is resolved as @code{mpz_class}.
+
+@example
+mpz_class f(1), g(2);
+fun (f, g);    // Good
+@end example
+
+@noindent
+But when one of the arguments is an expression, it doesn't work.
+
+@example
+mpz_class f(1), g(2), h(3);
+fun (f, g+h);  // Bad
+@end example
+
+This is because @code{g+h} ends up being a certain expression template type
+internal to @code{gmpxx.h}, which the C++ template resolution rules are unable
+to automatically convert to @code{mpz_class}.  The workaround is simply to add
+an explicit cast.
+
+@example
+mpz_class f(1), g(2), h(3);
+fun (f, mpz_class(g+h));  // Good
+@end example
+
+Similarly, within @code{fun} it may be necessary to cast an expression to type
+@code{T} when calling a templated @code{fun2}.
+
+@example
+template <class T>
+void fun (T f, T g)
+@{
+  fun2 (f, f+g);     // Bad
+@}
+
+template <class T>
+void fun (T f, T g)
+@{
+  fun2 (f, T(f+g));  // Good
+@}
+@end example
+
+@item C++11
+C++11 provides several new ways in which types can be inferred: @code{auto},
+@code{decltype}, etc. While they can be very convenient, they don't mix well
+with expression templates. In this example, the addition is performed twice,
+as if we had defined @code{sum} as a macro.
+
+@example
+mpz_class z = 33;
+auto sum = z + z;
+mpz_class prod = sum * sum;
+@end example
+
+This other example may crash, though some compilers might make it look like
+it is working, because the expression @code{z+z} goes out of scope before it
+is evaluated.
+
+@example
+mpz_class z = 33;
+auto sum = z + z + z;
+mpz_class prod = sum * 2;
+@end example
+
+It is thus strongly recommended to avoid @code{auto} anywhere a GMP C++
+expression may appear.

+is @code{NULL}, the corresponding default function is used.
+
+These functions will be used for all memory allocation done by GMP, apart from
+temporary space from @code{alloca} if that function is available and GMP is
+configured to use it (@pxref{Build Options}).
+
+@strong{Be sure to call @code{mp_set_memory_functions} only when there are no
+active GMP objects allocated using the previous memory functions!  Usually
+that means calling it before any other GMP function.}
+@end deftypefun
+
+The functions supplied should fit the following declarations:
+
+@deftypevr Function {void *} allocate_function (size_t @var{alloc_size})
+Return a pointer to newly allocated space with at least @var{alloc_size}
+bytes.
+@end deftypevr
+
+@deftypevr Function {void *} reallocate_function (void *@var{ptr}, size_t @var{old_size}, size_t @var{new_size})
+Resize a previously allocated block @var{ptr} of @var{old_size} bytes to be
+@var{new_size} bytes.
+
+The block may be moved if necessary or if desired, and in that case the
+smaller of @var{old_size} and @var{new_size} bytes must be copied to the new
+location.  The return value is a pointer to the resized block, that being the
+new location if moved or just @var{ptr} if not.
+
+@var{ptr} is never @code{NULL}, it's always a previously allocated block.
+@var{new_size} may be bigger or smaller than @var{old_size}.
+@end deftypevr
+
+@deftypevr Function void free_function (void *@var{ptr}, size_t @var{size})
+De-allocate the space pointed to by @var{ptr}.
+
+@var{ptr} is never @code{NULL}, it's always a previously allocated block of
+@var{size} bytes.
+@end deftypevr
+
+A @dfn{byte} here means the unit used by the @code{sizeof} operator.
+
+The @var{reallocate_function} parameter @var{old_size} and the
+@var{free_function} parameter @var{size} are passed for convenience, but of
+course they can be ignored if not needed by an implementation.  The default
+functions using @code{malloc} and friends for instance don't use them.
+
+No error return is allowed from any of these functions, if they return then
+they must have performed the specified operation.  In particular note that
+@var{allocate_function} or @var{reallocate_function} mustn't return
+@code{NULL}.
+
+Getting a different fatal error action is a good use for custom allocation
+functions, for example giving a graphical dialog rather than the default print
+to @code{stderr}.  How much is possible when genuinely out of memory is
+another question though.
+
+There's currently no defined way for the allocation functions to recover from
+an error such as out of memory, they must terminate program execution.  A
+@code{longjmp} or throwing a C++ exception will have undefined results.  This
+may change in the future.
+
+GMP may use allocated blocks to hold pointers to other allocated blocks.  This
+will limit the assumptions a conservative garbage collection scheme can make.
+
+Since the default GMP allocation uses @code{malloc} and friends, those
+functions will be linked in even if the first thing a program does is an
+@code{mp_set_memory_functions}.  It's necessary to change the GMP sources if
+this is a problem.

+@subsection Basecase Multiplication
+
+Basecase N@cross{}M multiplication is a straightforward rectangular set of
+cross-products, the same as long multiplication done by hand and for that
+reason sometimes known as the schoolbook or grammar school method.  This is an
+@m{O(NM),O(N*M)} algorithm.  See Knuth section 4.3.1 algorithm M
+(@pxref{References}), and the @file{mpn/generic/mul_basecase.c} code.
+
+Assembly implementations of @code{mpn_mul_basecase} are essentially the same
+as the generic C code, but have all the usual assembly tricks and
+obscurities introduced for speed.
+
+A square can be done in roughly half the time of a multiply, by using the fact
+that the cross products above and below the diagonal are the same.  A triangle
+of products below the diagonal is formed, doubled (left shift by one bit), and
+then the products on the diagonal added.  This can be seen in
+@file{mpn/generic/sqr_basecase.c}.  Again the assembly implementations take
+essentially the same approach.

+In practice squaring isn't a full 2@cross{} faster than multiplying, it's

+
+The term @m{(x_1-x_0)(y_1-y_0),(x1-x0)*(y1-y0)} is best calculated as an
+absolute value, and the sign used to choose to add or subtract.  Notice the
+sum @m{\mathop{\rm high}(x_0y_0)+\mathop{\rm low}(x_1y_1),
+high(x0*y0)+low(x1*y1)} occurs twice, so it's possible to do @m{5k,5*k} limb
+additions, rather than @m{6k,6*k}, but in GMP extra function call overheads
+outweigh the saving.
+
+Squaring is similar to multiplying, but with @math{x=y} the formula reduces to
+an equivalent with three squares,
+
+@display
+@m{x^2 = (b^2+b)x_1^2 - b(x_1-x_0)^2 + (b+1)x_0^2,
+   x^2 = (b^2+b)*x1^2 - b*(x1-x0)^2 + (b+1)*x0^2}
+@end display
+
+The final result is accumulated from those three squares the same way as for
+the three multiplies above.  The middle term @m{(x_1-x_0)^2,(x1-x0)^2} is now
+always positive.
+
+A similar formula for both multiplying and squaring can be constructed with a
+middle term @m{(x_1+x_0)(y_1+y_0),(x1+x0)*(y1+y0)}.  But those sums can exceed
+@math{k} limbs, leading to more carry handling and additions than the form
+above.
+
+Karatsuba multiplication is asymptotically an @math{O(N^@W{1.585})} algorithm,
+the exponent being @m{\log3/\log2,log(3)/log(2)}, representing 3 multiplies
+each @math{1/2} the size of the inputs.  This is a big improvement over the
+basecase multiply at @math{O(N^2)} and the advantage soon overcomes the extra
+additions Karatsuba performs.  @code{MUL_TOOM22_THRESHOLD} can be as little
+as 10 limbs.  The @code{SQR} threshold is usually about twice the @code{MUL}.
+
+The basecase algorithm will take a time of the form @m{M(N) = aN^2 + bN + c,
+M(N) = a*N^2 + b*N + c} and the Karatsuba algorithm @m{K(N) = 3M(N/2) + dN +
+e, K(N) = 3*M(N/2) + d*N + e}, which expands to @m{K(N) = {3\over4} aN^2 +
+{3\over2} bN + 3c + dN + e, K(N) = 3/4*a*N^2 + 3/2*b*N + 3*c + d*N + e}.  The
+factor @m{3\over4, 3/4} for @math{a} means per-crossproduct speedups in the
+basecase code will increase the threshold since they benefit @math{M(N)} more
+than @math{K(N)}.  And conversely the @m{3\over2, 3/2} for @math{b} means

+This is a set of five equations in five unknowns, and some elementary linear
+algebra quickly isolates each @m{w_i,w[i]}.  This involves adding or
+subtracting one @math{W(t)} value from another, and a couple of divisions by
+powers of 2 and one division by 3, the latter using the special
+@code{mpn_divexact_by3} (@pxref{Exact Division}).
+
+The conversion of @math{W(t)} values to the coefficients is interpolation.  A
+polynomial of degree 4 like @math{W(t)} is uniquely determined by values known
+at 5 different points.  The points are arbitrary and can be chosen to make the
+linear equations come out with a convenient set of steps for quickly isolating
+the @m{w_i,w[i]}.
+
+Squaring follows the same procedure as multiplication, but there's only one
+@math{X(t)} and it's evaluated at the 5 points, and those values squared to
+give values of @math{W(t)}.  The interpolation is then identical, and in fact
+the same @code{toom_interpolate_5pts} subroutine is used for both squaring and
+multiplying.
+
+Toom-3 is asymptotically @math{O(N^@W{1.465})}, the exponent being
+@m{\log5/\log3,log(5)/log(3)}, representing 5 recursive multiplies of 1/3 the
+original size each.  This is an improvement over Karatsuba at
+@math{O(N^@W{1.585})}, though Toom does more work in the evaluation and
+interpolation and so it only realizes its advantage above a certain size.
+
+Near the crossover between Toom-3 and Karatsuba there's generally a range of
+sizes where the difference between the two is small.
+@code{MUL_TOOM33_THRESHOLD} is a somewhat arbitrary point in that range and
+successive runs of the tune program can give different values due to small
+variations in measuring.  A graph of time versus size for the two shows the
+effect, see @file{tune/README}.
+
+At the fairly small sizes where the Toom-3 thresholds occur it's worth
+remembering that the asymptotic behaviour for Karatsuba and Toom-3 can't be
+expected to make accurate predictions, due of course to the big influence of
+all sorts of overheads, and the fact that only a few recursions of each are
+being performed.  Even at large sizes there's a good chance machine dependent
+effects like cache architecture will mean actual performance deviates from
+what might be predicted.
+
+The formula given for the Karatsuba algorithm (@pxref{Karatsuba
+Multiplication}) has an equivalent for Toom-3 involving only five multiplies,
+but this would be complicated and unenlightening.
+
+An alternate view of Toom-3 can be found in Zuras (@pxref{References}), using
+a vector to represent the @math{x} and @math{y} splits and a matrix
+multiplication for the evaluation and interpolation stages.  The matrix
+inverses are not meant to be actually used, and they have elements with values
+much greater than in fact arise in the interpolation steps.  The diagram shown
+for the 3-way is attractive, but again doesn't have to be implemented that way
+and for example with a bit of rearrangement just one division by 6 can be
+done.

+
+The Toom algorithms described above (@pxref{Toom 3-Way Multiplication},
+@pxref{Toom 4-Way Multiplication}) generalizes to split into an arbitrary
+number of pieces. In general a split of two equally long operands into
+@math{r} pieces leads to evaluations and pointwise multiplications done at
+@m{2r-1,2*r-1} points. To fully exploit symmetries it would be better to have
+a multiple of 4 points, that's why for higher degree Toom'n'half is used.
+
+Toom'n'half means that the existence of one more piece is considered for a
+single operand. It can be virtual, i.e. zero, or real, when the two operand
+are not exactly balanced. By choosing an even @math{r},
+Toom-@m{r{1\over2},r+1/2} requires @math{2r} points, a multiple of four.
+
+The quadruplets of points include 0, @m{\infty,inf}, +1, -1 and
+@m{\pm2^i,+-2^i}, @m{\pm2^{-i},+-2^-i} . Each of them giving shortcuts for the
+evaluation phase and for some steps in the interpolation phase. Further tricks
+are used to reduce the memory footprint of the whole multiplication algorithm
+to a memory buffer equal in size to the result of the product.

+@subsection FFT Multiplication
+@cindex FFT multiplication
+@cindex Fast Fourier Transform
+
+At large to very large sizes a Fermat style FFT multiplication is used,
+following Sch@"onhage and Strassen (@pxref{References}).  Descriptions of FFTs
+in various forms can be found in many textbooks, for instance Knuth section
+4.3.3 part C or Lipson chapter IX@.  A brief description of the form used in
+GMP is given here.
+
+The multiplication done is @m{xy \bmod 2^N+1, x*y mod 2^N+1}, for a given
+@math{N}.  A full product @m{xy,x*y} is obtained by choosing @m{N \ge
+\mathop{\rm bits}(x)+\mathop{\rm bits}(y), N>=bits(x)+bits(y)} and padding
+@math{x} and @math{y} with high zero limbs.  The modular product is the native
+form for the algorithm, so padding to get a full product is unavoidable.
+
+The algorithm follows a split, evaluate, pointwise multiply, interpolate and
+combine similar to that described above for Karatsuba and Toom-3.  A @math{k}
+parameter controls the split, with an FFT-@math{k} splitting into @math{2^k}
+pieces of @math{M=N/2^k} bits each.  @math{N} must be a multiple of
+@m{2^k\times@code{mp\_bits\_per\_limb}, (2^k)*@nicode{mp_bits_per_limb}} so
+the split falls on limb boundaries, avoiding bit shifts in the split and
+combine stages.
+
+The evaluations, pointwise multiplications, and interpolation, are all done
+modulo @m{2^{N'}+1, 2^N'+1} where @math{N'} is @math{2M+k+3} rounded up to a
+multiple of @math{2^k} and of @code{mp_bits_per_limb}.  The results of
+interpolation will be the following negacyclic convolution of the input
+pieces, and the choice of @math{N'} ensures these sums aren't truncated.
+@tex
+$$ w_n = \sum_{{i+j = b2^k+n}\atop{b=0,1}} (-1)^b x_i y_j $$
+@end tex
+@ifnottex
+
+@example
+           ---
+           \         b
+w[n] =     /     (-1) * x[i] * y[j]
+           ---
+       i+j==b*2^k+n
+          b=0,1
+@end example
+
+@end ifnottex
+The points used for the evaluation are @math{g^i} for @math{i=0} to
+@math{2^k-1} where @m{g=2^{2N'/2^k}, g=2^(2N'/2^k)}.  @math{g} is a
+@m{2^k,2^k'}th root of unity mod @m{2^{N'}+1,2^N'+1}, which produces necessary
+cancellations at the interpolation stage, and it's also a power of 2 so the
+fast Fourier transforms used for the evaluation and interpolation do only
+shifts, adds and negations.
+
+The pointwise multiplications are done modulo @m{2^{N'}+1, 2^N'+1} and either
+recurse into a further FFT or use a plain multiplication (Toom-3, Karatsuba or
+basecase), whichever is optimal at the size @math{N'}.  The interpolation is
+an inverse fast Fourier transform.  The resulting set of sums of @m{x_iy_j,
+x[i]*y[j]} are added at appropriate offsets to give the final result.
+
+Squaring is the same, but @math{x} is the only input so it's one transform at
+the evaluate stage and the pointwise multiplies are squares.  The
+interpolation is the same.
+
+For a mod @math{2^N+1} product, an FFT-@math{k} is an @m{O(N^{k/(k-1)}),
+O(N^(k/(k-1)))} algorithm, the exponent representing @math{2^k} recursed
+modular multiplies each @m{1/2^{k-1},1/2^(k-1)} the size of the original.
+Each successive @math{k} is an asymptotic improvement, but overheads mean each
+is only faster at bigger and bigger sizes.  In the code, @code{MUL_FFT_TABLE}
+and @code{SQR_FFT_TABLE} are the thresholds where each @math{k} is used.  Each
+new @math{k} effectively swaps some multiplying for some shifts, adds and
+overheads.
+
+A mod @math{2^N+1} product can be formed with a normal
+@math{N@cross{}N@rightarrow{}2N} bit multiply plus a subtraction, so an FFT
+and Toom-3 etc can be compared directly.  A @math{k=4} FFT at
+@math{O(N^@W{1.333})} can be expected to be the first faster than Toom-3 at
+@math{O(N^@W{1.465})}.  In practice this is what's found, with
+@code{MUL_FFT_MODF_THRESHOLD} and @code{SQR_FFT_MODF_THRESHOLD} being between
+300 and 1000 limbs, depending on the CPU@.  So far it's been found that only
+very large FFTs recurse into pointwise multiplies above these sizes.
+
+When an FFT is to give a full product, the change of @math{N} to @math{2N}
+doesn't alter the theoretical complexity for a given @math{k}, but for the
+purposes of considering where an FFT might be first used it can be assumed
+that the FFT is recursing into a normal multiply and that on that basis it's
+doing @math{2^k} recursed multiplies each @m{1/2^{k-2},1/2^(k-2)} the size of
+the inputs, making it @m{O(N^{k/(k-2)}), O(N^(k/(k-2)))}.  This would mean
+@math{k=7} at @math{O(N^@W{1.4})} would be the first FFT faster than Toom-3.
+In practice @code{MUL_FFT_THRESHOLD} and @code{SQR_FFT_THRESHOLD} have been
+found to be in the @math{k=8} range, somewhere between 3000 and 10000 limbs.
+
+The way @math{N} is split into @math{2^k} pieces and then @math{2M+k+3} is
+rounded up to a multiple of @math{2^k} and @code{mp_bits_per_limb} means that
+when @math{2^k@ge{}@nicode{mp\_bits\_per\_limb}} the effective @math{N} is a
+multiple of @m{2^{2k-1},2^(2k-1)} bits.  The @math{+k+3} means some values of
+@math{N} just under such a multiple will be rounded to the next.  The
+complexity calculations above assume that a favourable size is used, meaning
+one which isn't padded through rounding, and it's also assumed that the extra
+@math{+k+3} bits are negligible at typical FFT sizes.
+
+The practical effect of the @m{2^{2k-1},2^(2k-1)} constraint is to introduce a
+step-effect into measured speeds.  For example @math{k=8} will round @math{N}
+up to a multiple of 32768 bits, so for a 32-bit limb there'll be 512 limb
+groups of sizes for which @code{mpn_mul_n} runs at the same speed.  Or for
+@math{k=9} groups of 2048 limbs, @math{k=10} groups of 8192 limbs, etc.  In
+practice it's been found each @math{k} is used at quite small multiples of its
+size constraint and so the step effect is quite noticeable in a time versus
+size graph.
+
+The threshold determinations currently measure at the mid-points of size

+
+The Toom algorithms described above (@pxref{Toom 3-Way Multiplication},
+@pxref{Toom 4-Way Multiplication}) generalizes to split into an arbitrary
+number of pieces, as per Knuth section 4.3.3 algorithm C@.  This is not
+currently used.  The notes here are merely for interest.
+
+In general a split into @math{r+1} pieces is made, and evaluations and
+pointwise multiplications done at @m{2r+1,2*r+1} points.  A 4-way split does 7
+pointwise multiplies, 5-way does 9, etc.  Asymptotically an @math{(r+1)}-way
+algorithm is @m{O(N^{log(2r+1)/log(r+1)}), O(N^(log(2*r+1)/log(r+1)))}.  Only
+the pointwise multiplications count towards big-@math{O} complexity, but the
+time spent in the evaluate and interpolate stages grows with @math{r} and has
+a significant practical impact, with the asymptotic advantage of each @math{r}
+realized only at bigger and bigger sizes.  The overheads grow as
+@m{O(Nr),O(N*r)}, whereas in an @math{r=2^k} FFT they grow only as @m{O(N \log
+r), O(N*log(r))}.
+
+Knuth algorithm C evaluates at points 0,1,2,@dots{},@m{2r,2*r}, but exercise 4
+uses @math{-r},@dots{},0,@dots{},@math{r} and the latter saves some small
+multiplies in the evaluate stage (or rather trades them for additions), and
+has a further saving of nearly half the interpolate steps.  The idea is to
+separate odd and even final coefficients and then perform algorithm C steps C7
+and C8 on them separately.  The divisors at step C7 become @math{j^2} and the
+multipliers at C8 become @m{2tj-j^2,2*t*j-j^2}.
+
+Splitting odd and even parts through positive and negative points can be
+thought of as using @math{-1} as a square root of unity.  If a 4th root of
+unity was available then a further split and speedup would be possible, but no
+such root exists for plain integers.  Going to complex integers with
+@m{i=\sqrt{-1}, i=sqrt(-1)} doesn't help, essentially because in Cartesian
+form it takes three real multiplies to do a complex multiply.  The existence
+of @m{2^k,2^k'}th roots of unity in a suitable ring or field lets the fast
+Fourier transform keep splitting and get to @m{O(N \log r), O(N*log(r))}.
+
+Floating point FFTs use complex numbers approximating Nth roots of unity.
+Some processors have special support for such FFTs.  But these are not used in
+GMP since it's very difficult to guarantee an exact result (to some number of
+bits).  An occasional difference of 1 in the last bit might not matter to a
+typical signal processing algorithm, but is of course of vital importance to
+GMP.

+@subsection Single Limb Division
+
+N@cross{}1 division is implemented using repeated 2@cross{}1 divisions from
+high to low, either with a hardware divide instruction or a multiplication by
+inverse, whichever is best on a given CPU.
+
+The multiply by inverse follows ``Improved division by invariant integers'' by
+M@"oller and Granlund (@pxref{References}) and is implemented as
+@code{udiv_qrnnd_preinv} in @file{gmp-impl.h}.  The idea is to have a
+fixed-point approximation to @math{1/d} (see @code{invert_limb}) and then
+multiply by the high limb (plus one bit) of the dividend to get a quotient
+@math{q}.  With @math{d} normalized (high bit set), @math{q} is no more than 1
+too small.  Subtracting @m{qd,q*d} from the dividend gives a remainder, and
+reveals whether @math{q} or @math{q-1} is correct.
+
+The result is a division done with two multiplications and four or five
+arithmetic operations.  On CPUs with low latency multipliers this can be much
+faster than a hardware divide, though the cost of calculating the inverse at
+the start may mean it's only better on inputs bigger than say 4 or 5 limbs.
+
+When a divisor must be normalized, either for the generic C
+@code{__udiv_qrnnd_c} or the multiply by inverse, the division performed is
+actually @m{a2^k,a*2^k} by @m{d2^k,d*2^k} where @math{a} is the dividend and
+@math{k} is the power necessary to have the high bit of @m{d2^k,d*2^k} set.
+The bit shifts for the dividend are usually accomplished ``on the fly''
+meaning by extracting the appropriate bits at each step.  Done this way the
+quotient limbs come out aligned ready to store.  When only the remainder is
+wanted, an alternative is to take the dividend limbs unshifted and calculate
+@m{r = a \bmod d2^k, r = a mod d*2^k} followed by an extra final step @m{r2^k
+\bmod d2^k, r*2^k mod d*2^k}.  This can help on CPUs with poor bit shifts or
+few registers.
+
+The multiply by inverse can be done two limbs at a time.  The calculation is
+basically the same, but the inverse is two limbs and the divisor treated as if
+padded with a low zero limb.  This means more work, since the inverse will
+need a 2@cross{}2 multiply, but the four 1@cross{}1s to do that are
+independent and can therefore be done partly or wholly in parallel.  Likewise
+for a 2@cross{}1 calculating @m{qd,q*d}.  The net effect is to process two
+limbs with roughly the same two multiplies worth of latency that one limb at a
+time gives.  This extends to 3 or 4 limbs at a time, though the extra work to
+apply the inverse will almost certainly soon reach the limits of multiplier
+throughput.
+
+A similar approach in reverse can be taken to process just half a limb at a
+time if the divisor is only a half limb.  In this case the 1@cross{}1 multiply
+for the inverse effectively becomes two @m{{1\over2}\times1, (1/2)x1} for each
+limb, which can be a saving on CPUs with a fast half limb multiply, or in fact
+if the only multiply is a half limb, and especially if it's not pipelined.

+@node Basecase Division, Divide and Conquer Division, Single Limb Division, Division Algorithms
+@subsection Basecase Division
+
+Basecase N@cross{}M division is like long division done by hand, but in base
+@m{2\GMPraise{@code{mp\_bits\_per\_limb}}, 2^mp_bits_per_limb}.  See Knuth
+section 4.3.1 algorithm D, and @file{mpn/generic/sb_divrem_mn.c}.
+
+Briefly stated, while the dividend remains larger than the divisor, a high
+quotient limb is formed and the N@cross{}1 product @m{qd,q*d} subtracted at
+the top end of the dividend.  With a normalized divisor (most significant bit
+set), each quotient limb can be formed with a 2@cross{}1 division and a
+1@cross{}1 multiplication plus some subtractions.  The 2@cross{}1 division is
+by the high limb of the divisor and is done either with a hardware divide or a
+multiply by inverse (the same as in @ref{Single Limb Division}) whichever is
+faster.  Such a quotient is sometimes one too big, requiring an addback of the
+divisor, but that happens rarely.
+
+With Q=N@minus{}M being the number of quotient limbs, this is an
+@m{O(QM),O(Q*M)} algorithm and will run at a speed similar to a basecase
+Q@cross{}M multiplication, differing in fact only in the extra multiply and

+
+@node Divide and Conquer Division, Block-Wise Barrett Division, Basecase Division, Division Algorithms
+@subsection Divide and Conquer Division
+
+For divisors larger than @code{DC_DIV_QR_THRESHOLD}, division is done by dividing.
+Or to be precise by a recursive divide and conquer algorithm based on work by
+Moenck and Borodin, Jebelean, and Burnikel and Ziegler (@pxref{References}).
+
+The algorithm consists essentially of recognising that a 2N@cross{}N division
+can be done with the basecase division algorithm (@pxref{Basecase Division}),
+but using N/2 limbs as a base, not just a single limb.  This way the
+multiplications that arise are (N/2)@cross{}(N/2) and can take advantage of
+Karatsuba and higher multiplication algorithms (@pxref{Multiplication
+Algorithms}).  The two ``digits'' of the quotient are formed by recursive
+N@cross{}(N/2) divisions.
+
+If the (N/2)@cross{}(N/2) multiplies are done with a basecase multiplication
+then the work is about the same as a basecase division, but with more function
+call overheads and with some subtractions separated from the multiplies.
+These overheads mean that it's only when N/2 is above
+@code{MUL_TOOM22_THRESHOLD} that divide and conquer is of use.
+
+@code{DC_DIV_QR_THRESHOLD} is based on the divisor size N, so it will be somewhere
+above twice @code{MUL_TOOM22_THRESHOLD}, but how much above depends on the
+CPU@.  An optimized @code{mpn_mul_basecase} can lower @code{DC_DIV_QR_THRESHOLD} a
+little by offering a ready-made advantage over repeated @code{mpn_submul_1}
+calls.
+
+Divide and conquer is asymptotically @m{O(M(N)\log N),O(M(N)*log(N))} where
+@math{M(N)} is the time for an N@cross{}N multiplication done with FFTs.  The
+actual time is a sum over multiplications of the recursed sizes, as can be
+seen near the end of section 2.2 of Burnikel and Ziegler.  For example, within
+the Toom-3 range, divide and conquer is @m{2.63M(N), 2.63*M(N)}.  With higher
+algorithms the @math{M(N)} term improves and the multiplier tends to @m{\log
+N, log(N)}.  In practice, at moderate to large sizes, a 2N@cross{}N division
+is about 2 to 4 times slower than an N@cross{}N multiplication.

+
+@node Block-Wise Barrett Division, Exact Division, Divide and Conquer Division, Division Algorithms
+@subsection Block-Wise Barrett Division
+
+For the largest divisions, a block-wise Barrett division algorithm is used.
+Here, the divisor is inverted to a precision determined by the relative size of
+the dividend and divisor.  Blocks of quotient limbs are then generated by
+multiplying blocks from the dividend by the inverse.
+
+Our block-wise algorithm computes a smaller inverse than in the plain Barrett
+algorithm.  For a @math{2n/n} division, the inverse will be just @m{\lceil n/2
+\rceil, ceil(n/2)} limbs.
+
+
+@node Exact Division, Exact Remainder, Block-Wise Barrett Division, Division Algorithms
+@subsection Exact Division
+
+
+A so-called exact division is when the dividend is known to be an exact
+multiple of the divisor.  Jebelean's exact division algorithm uses this
+knowledge to make some significant optimizations (@pxref{References}).
+
+The idea can be illustrated in decimal for example with 368154 divided by
+543.  Because the low digit of the dividend is 4, the low digit of the
+quotient must be 8.  This is arrived at from @m{4 \mathord{\times} 7 \bmod 10,
+4*7 mod 10}, using the fact 7 is the modular inverse of 3 (the low digit of
+the divisor), since @m{3 \mathord{\times} 7 \mathop{\equiv} 1 \bmod 10, 3*7
+@equiv{} 1 mod 10}.  So @m{8\mathord{\times}543 = 4344,8*543=4344} can be
+subtracted from the dividend leaving 363810.  Notice the low digit has become
+zero.
+
+The procedure is repeated at the second digit, with the next quotient digit 7
+(@m{1 \mathord{\times} 7 \bmod 10, 7 @equiv{} 1*7 mod 10}), subtracting
+@m{7\mathord{\times}543 = 3801,7*543=3801}, leaving 325800.  And finally at
+the third digit with quotient digit 6 (@m{8 \mathord{\times} 7 \bmod 10, 8*7
+mod 10}), subtracting @m{6\mathord{\times}543 = 3258,6*543=3258} leaving 0.
+So the quotient is 678.
+
+Notice however that the multiplies and subtractions don't need to extend past
+the low three digits of the dividend, since that's enough to determine the
+three quotient digits.  For the last quotient digit no subtraction is needed
+at all.  On a 2N@cross{}N division like this one, only about half the work of
+a normal basecase division is necessary.
+
+For an N@cross{}M exact division producing Q=N@minus{}M quotient limbs, the
+saving over a normal basecase division is in two parts.  Firstly, each of the
+Q quotient limbs needs only one multiply, not a 2@cross{}1 divide and
+multiply.  Secondly, the crossproducts are reduced when @math{Q>M} to
+@m{QM-M(M+1)/2,Q*M-M*(M+1)/2}, or when @math{Q@le{}M} to @m{Q(Q-1)/2,
+Q*(Q-1)/2}.  Notice the savings are complementary.  If Q is big then many
+divisions are saved, or if Q is small then the crossproducts reduce to a small
+number.
+
+The modular inverse used is calculated efficiently by @code{binvert_limb} in
+@file{gmp-impl.h}.  This does four multiplies for a 32-bit limb, or six for a
+64-bit limb.  @file{tune/modlinv.c} has some alternate implementations that
+might suit processors better at bit twiddling than multiplying.
+
+The sub-quadratic exact division described by Jebelean in ``Exact Division
+with Karatsuba Complexity'' is not currently implemented.  It uses a
+rearrangement similar to the divide and conquer for normal division
+(@pxref{Divide and Conquer Division}), but operating from low to high.  A
+further possibility not currently implemented is ``Bidirectional Exact Integer
+Division'' by Krandick and Jebelean which forms quotient limbs from both the
+high and low ends of the dividend, and can halve once more the number of
+crossproducts needed in a 2N@cross{}N division.
+
+A special case exact division by 3 exists in @code{mpn_divexact_by3},
+supporting Toom-3 multiplication and @code{mpq} canonicalizations.  It forms
+quotient digits with a multiply by the modular inverse of 3 (which is
+@code{0xAA..AAB}) and uses two comparisons to determine a borrow for the next
+limb.  The multiplications don't need to be on the dependent chain, as long as
+the effect of the borrows is applied, which can help chips with pipelined
+multipliers.

+If the exact division algorithm is done with a full subtraction at each stage
+and the dividend isn't a multiple of the divisor, then low zero limbs are

+@end tex
+@ifnottex
+
+@example
+a = q*d + r*b^n
+@end example
+
+@end ifnottex
+@math{n} represents the number of zero limbs produced by the subtractions,
+that being the number of limbs produced for @math{q}.  @math{r} will be in the
+range @math{0@le{}r<d} and can be viewed as a remainder, but one shifted up by
+a factor of @math{b^n}.
+
+Carrying out full subtractions at each stage means the same number of cross
+products must be done as a normal division, but there's still some single limb
+divisions saved.  When @math{d} is a single limb some simplifications arise,
+providing good speedups on a number of processors.
+
+The functions @code{mpn_divexact_by3}, @code{mpn_modexact_1_odd} and the
+internal @code{mpn_redc_X} functions differ subtly in how they return @math{r},
+leading to some negations in the above formula, but all are essentially the
+same.
+
+@cindex Divisibility algorithm
+@cindex Congruence algorithm
+Clearly @math{r} is zero when @math{a} is a multiple of @math{d}, and this
+leads to divisibility or congruence tests which are potentially more efficient
+than a normal division.
+
+The factor of @math{b^n} on @math{r} can be ignored in a GCD when @math{d} is
+odd, hence the use of @code{mpn_modexact_1_odd} by @code{mpn_gcd_1} and
+@code{mpz_kronecker_ui} etc (@pxref{Greatest Common Divisor Algorithms}).
+
+Montgomery's REDC method for modular multiplications uses operands of the form
+of @m{xb^{-n}, x*b^-n} and @m{yb^{-n}, y*b^-n} and on calculating @m{(xb^{-n})
+(yb^{-n}), (x*b^-n)*(y*b^-n)} uses the factor of @math{b^n} in the exact
+remainder to reach a product in the same form @m{(xy)b^{-n}, (x*y)*b^-n}
+(@pxref{Modular Powering Algorithm}).
+
+Notice that @math{r} generally gives no useful information about the ordinary
+remainder @math{a @bmod d} since @math{b^n @bmod d} could be anything.  If
+however @math{b^n @equiv{} 1 @bmod d}, then @math{r} is the negative of the
+ordinary remainder.  This occurs whenever @math{d} is a factor of
+@math{b^n-1}, as for example with 3 in @code{mpn_divexact_by3}.  For a 32 or
+64 bit limb other such factors include 5, 17 and 257, but no particular use

+@subsection Small Quotient Division
+
+An N@cross{}M division where the number of quotient limbs Q=N@minus{}M is
+small can be optimized somewhat.
+
+An ordinary basecase division normalizes the divisor by shifting it to make
+the high bit set, shifting the dividend accordingly, and shifting the
+remainder back down at the end of the calculation.  This is wasteful if only a
+few quotient limbs are to be formed.  Instead a division of just the top
+@m{\rm2Q,2*Q} limbs of the dividend by the top Q limbs of the divisor can be
+used to form a trial quotient.  This requires only those limbs normalized, not
+the whole of the divisor and dividend.
+
+A multiply and subtract then applies the trial quotient to the M@minus{}Q
+unused limbs of the divisor and N@minus{}Q dividend limbs (which includes Q
+limbs remaining from the trial quotient division).  The starting trial
+quotient can be 1 or 2 too big, but all cases of 2 too big and most cases of 1
+too big are detected by first comparing the most significant limbs that will
+arise from the subtraction.  An addback is done if the quotient still turns

+
+This whole procedure is essentially the same as one step of the basecase

+@subsection Binary GCD
+
+At small sizes GMP uses an @math{O(N^2)} binary style GCD@.  This is described
+in many textbooks, for example Knuth section 4.5.2 algorithm B@.  It simply
+consists of successively reducing odd operands @math{a} and @math{b} using
+
+@quotation
+@math{a,b = @abs{}(a-b),@min{}(a,b)} @*
+strip factors of 2 from @math{a}
+@end quotation
+
+The Euclidean GCD algorithm, as per Knuth algorithms E and A, repeatedly
+computes the quotient @m{q = \lfloor a/b \rfloor, q = floor(a/b)} and replaces
+@math{a,b} by @math{v, u - q v}. The binary algorithm has so far been found to
+be faster than the Euclidean algorithm everywhere.  One reason the binary
+method does well is that the implied quotient at each step is usually small,
+so often only one or two subtractions are needed to get the same effect as a
+division.  Quotients 1, 2 and 3 for example occur 67.7% of the time, see Knuth
+section 4.5.3 Theorem E.
+
+When the implied quotient is large, meaning @math{b} is much smaller than
+@math{a}, then a division is worthwhile.  This is the basis for the initial
+@math{a @bmod b} reductions in @code{mpn_gcd} and @code{mpn_gcd_1} (the latter
+for both N@cross{}1 and 1@cross{}1 cases).  But after that initial reduction,
+big quotients occur too rarely to make it worth checking for them.
+
+@sp 1
+The final @math{1@cross{}1} GCD in @code{mpn_gcd_1} is done in the generic C
+code as described above.  For two N-bit operands, the algorithm takes about
+0.68 iterations per bit.  For optimum performance some attention needs to be
+paid to the way the factors of 2 are stripped from @math{a}.
+
+Firstly it may be noted that in twos complement the number of low zero bits on
+@math{a-b} is the same as @math{b-a}, so counting or testing can begin on
+@math{a-b} without waiting for @math{@abs{}(a-b)} to be determined.
+
+A loop stripping low zero bits tends not to branch predict well, since the
+condition is data dependent.  But on average there's only a few low zeros, so
+an option is to strip one or two bits arithmetically then loop for more (as
+done for AMD K6).  Or use a lookup table to get a count for several bits then
+loop for more (as done for AMD K7).  An alternative approach is to keep just
+one of @math{a} or @math{b} odd and iterate
+
+@quotation
+@math{a,b = @abs{}(a-b), @min{}(a,b)} @*
+@math{a = a/2} if even @*
+@math{b = b/2} if even
+@end quotation
+
+This requires about 1.25 iterations per bit, but stripping of a single bit at
+each step avoids any branching.  Repeating the bit strip reduces to about 0.9
+iterations per bit, which may be a worthwhile tradeoff.
+
+Generally with the above approaches a speed of perhaps 6 cycles per bit can be
+achieved, which is still not terribly fast with for instance a 64-bit GCD
+taking nearly 400 cycles.  It's this sort of time which means it's not usually
+advantageous to combine a set of divisibility tests into a GCD.
+
+Currently, the binary algorithm is used for GCD only when @math{N < 3}.

+
+Lehmer's improvement of the Euclidean algorithms is based on the observation
+that the initial part of the quotient sequence depends only on the most
+significant parts of the inputs. The variant of Lehmer's algorithm used in GMP
+splits off the most significant two limbs, as suggested, e.g., in ``A
+Double-Digit Lehmer-Euclid Algorithm'' by Jebelean (@pxref{References}). The
+quotients of two double-limb inputs are collected as a 2 by 2 matrix with
+single-limb elements. This is done by the function @code{mpn_hgcd2}. The
+resulting matrix is applied to the inputs using @code{mpn_mul_1} and
+@code{mpn_submul_1}. Each iteration usually reduces the inputs by almost one
+limb. In the rare case of a large quotient, no progress can be made by
+examining just the most significant two limbs, and the quotient is computed
+using plain division.
+
+The resulting algorithm is asymptotically @math{O(N^2)}, just as the Euclidean
+algorithm and the binary algorithm. The quadratic part of the work are
+the calls to @code{mpn_mul_1} and @code{mpn_submul_1}. For small sizes, the
+linear work is also significant. There are roughly @math{N} calls to the
+@code{mpn_hgcd2} function. This function uses a couple of important
+optimizations:
+
+@itemize
+@item
+It uses the same relaxed notion of correctness as @code{mpn_hgcd} (see next
+section). This means that when called with the most significant two limbs of
+two large numbers, the returned matrix does not always correspond exactly to
+the initial quotient sequence for the two large numbers; the final quotient
+may sometimes be one off.
+
+@item
+It takes advantage of the fact the quotients are usually small. The division
+operator is not used, since the corresponding assembler instruction is very
+slow on most architectures. (This code could probably be improved further, it
+uses many branches that are unfriendly to prediction).

+matrix elements will also be of size roughly @math{N/2}.
+
+The HGCD base case uses Lehmer's algorithm, but with the above stop condition
+that returns reduced numbers and the corresponding transformation matrix
+half-way through. For inputs larger than @code{HGCD_THRESHOLD}, HGCD is
+computed recursively, using the divide and conquer algorithm in ``On

+(@pxref{References}). The recursive algorithm consists of these main
+steps.
+
+@itemize
+

+above @math{3N/2}.

+Compute @math{T = T_1 T_2}.
+
+@item
+Perform a small number of division and subtraction steps to satisfy the
+requirements, and return.
+@end itemize
+
+GCD is then implemented as a loop around HGCD, similarly to Lehmer's
+algorithm. Where Lehmer repeatedly chops off the top two limbs, calls
+@code{mpn_hgcd2}, and applies the resulting matrix to the full numbers, the
+sub-quadratic GCD chops off the most significant third of the limbs (the
+proportion is a tuning parameter, and @math{1/3} seems to be more efficient
+than, e.g, @math{1/2}), calls @code{mpn_hgcd}, and applies the resulting
+matrix. Once the input numbers are reduced to size below
+@code{GCD_DC_THRESHOLD}, Lehmer's algorithm is used for the rest of the work.
+
+The asymptotic running time of both HGCD and GCD is @m{O(M(N)\log N),O(M(N)*log(N))},
+where @math{M(N)} is the time for multiplying two @math{N}-limb numbers.

+
+The extended GCD function, or GCDEXT, calculates @math{@gcd{}(a,b)} and also
+cofactors @math{x} and @math{y} satisfying @m{ax+by=\gcd(a@C{}b),
+a*x+b*y=gcd(a@C{}b)}. All the algorithms used for plain GCD are extended to
+handle this case. The binary algorithm is used only for single-limb GCDEXT.
+Lehmer's algorithm is used for sizes up to @code{GCDEXT_DC_THRESHOLD}. Above
+this threshold, GCDEXT is implemented as a loop around HGCD, but with more
+book-keeping to keep track of the cofactors. This gives the same asymptotic
+running time as for GCD and HGCD, @m{O(M(N)\log N),O(M(N)*log(N))}
+
+One difference to plain GCD is that while the inputs @math{a} and @math{b} are
+reduced as the algorithm proceeds, the cofactors @math{x} and @math{y} grow in
+size. This makes the tuning of the chopping-point more difficult. The current
+code chops off the most significant half of the inputs for the call to HGCD in
+the first iteration, and the most significant two thirds for the remaining
+calls. This strategy could surely be improved. Also the stop condition for the
+loop, where Lehmer's algorithm is invoked once the inputs are reduced below
+@code{GCDEXT_DC_THRESHOLD}, could maybe be improved by taking into account the
+current size of the cofactors.

+

+
+Square roots are taken using the ``Karatsuba Square Root'' algorithm by Paul
+Zimmermann (@pxref{References}).
+
+An input @math{n} is split into four parts of @math{k} bits each, so with
+@math{b=2^k} we have @m{n = a_3b^3 + a_2b^2 + a_1b + a_0, n = a3*b^3 + a2*b^2
++ a1*b + a0}.  Part @ms{a,3} must be ``normalized'' so that either the high or
+second highest bit is set.  In GMP, @math{k} is kept on a limb boundary and
+the input is left shifted (by an even number of bits) to normalize.
+
+The square root of the high two parts is taken, by recursive application of
+the algorithm (bottoming out in a one-limb Newton's method),
+@tex
+$$ s',r' = \mathop{\rm sqrtrem} \> (a_3b + a_2) $$

+s = s1*b + q
+r = u*b + a0 - q^2
+@end example
+
+@end ifnottex
+The normalization requirement on @ms{a,3} means at this point @math{s} is

+The algorithm is expressed in a divide and conquer form, but as noted in the
+paper it can also be viewed as a discrete variant of Newton's method, or as a

+digits at a time.
+
+If the remainder @math{r} is not required then usually only a few high limbs
+of @math{r} and @math{u} need to be calculated to determine whether an
+adjustment to @math{s} is required.  This optimization is not currently
+implemented.
+
+In the Karatsuba multiplication range this algorithm is @m{O({3\over2}
+M(N/2)),O(1.5*M(N/2))}, where @math{M(n)} is the time to multiply two numbers
+of @math{n} limbs.  In the FFT multiplication range this grows to a bound of
+@m{O(6 M(N/2)),O(6*M(N/2))}.  In practice a factor of about 1.5 to 1.8 is
+found in the Karatsuba and Toom-3 ranges, growing to 2 or 3 in the FFT range.
+
+The algorithm does all its calculations in integers and the resulting

+@cindex Perfect square algorithm
+
+A significant fraction of non-squares can be quickly identified by checking
+whether the input is a quadratic residue modulo small integers.
+
+@code{mpz_perfect_square_p} first tests the input mod 256, which means just
+examining the low byte.  Only 44 different values occur for squares mod 256,
+so 82.8% of inputs can be immediately identified as non-squares.
+
+On a 32-bit system similar tests are done mod 9, 5, 7, 13 and 17, for a total
+99.25% of inputs identified as non-squares.  On a 64-bit system 97 is tested
+too, for a total 99.62%.
+
+These moduli are chosen because they're factors of @math{2^@W{24}-1} (or
+@math{2^@W{48}-1} for 64-bits), and such a remainder can be quickly taken just
+using additions (see @code{mpn_mod_34lsub1}).
+
+When nails are in use moduli are instead selected by the @file{gen-psqr.c}
+program and applied with an @code{mpn_mod_1}.  The same @math{2^@W{24}-1} or
+@math{2^@W{48}-1} could be done with nails using some extra bit shifts, but
+this is not currently implemented.
+
+In any case each modulus is applied to the @code{mpn_mod_34lsub1} or
+@code{mpn_mod_1} remainder and a table lookup identifies non-squares.  By
+using a ``modexact'' style calculation, and suitably permuted tables, just one
+multiply each is required, see the code for details.  Moduli are also combined
+to save operations, so long as the lookup tables don't become too big.
+@file{gen-psqr.c} does all the pre-calculations.
+
+A square root must still be taken for any value that passes these tests, to
+verify it's really a square and not one of the small fraction of non-squares
+that get through (i.e.@: a pseudo-square to all the tested bases).
+
+Clearly more residue tests could be done, @code{mpz_perfect_square_p} only
+uses a compact and efficient set.  Big inputs would probably benefit from more

+Conversions from binary to a power-of-2 radix use a simple and fast

+
+Conversions from binary to other radices use one of two algorithms.  Sizes
+below @code{GET_STR_PRECOMPUTE_THRESHOLD} use a basic @math{O(N^2)} method.
+Repeated divisions by @math{b^n} are made, where @math{b} is the radix and
+@math{n} is the biggest power that fits in a limb.  But instead of simply
+using the remainder @math{r} from such divisions, an extra divide step is done
+to give a fractional limb representing @math{r/b^n}.  The digits of @math{r}
+can then be extracted using multiplications by @math{b} rather than divisions.
+Special case code is provided for decimal, allowing multiplications by 10 to
+optimize to shifts and adds.
+
+Above @code{GET_STR_PRECOMPUTE_THRESHOLD} a sub-quadratic algorithm is used.
+For an input @math{t}, powers @m{b^{n2^i},b^(n*2^i)} of the radix are
+calculated, until a power between @math{t} and @m{\sqrt{t},sqrt(t)} is
+reached.  @math{t} is then divided by that largest power, giving a quotient
+which is the digits above that power, and a remainder which is those below.
+These two parts are in turn divided by the second highest power, and so on
+recursively.  When a piece has been divided down to less than
+@code{GET_STR_DC_THRESHOLD} limbs, the basecase algorithm described above is
+used.
+
+The advantage of this algorithm is that big divisions can make use of the
+sub-quadratic divide and conquer division (@pxref{Divide and Conquer
+Division}), and big divisions tend to have less overheads than lots of
+separate single limb divisions anyway.  But in any case the cost of
+calculating the powers @m{b^{n2^i},b^(n*2^i)} must first be overcome.
+
+@code{GET_STR_PRECOMPUTE_THRESHOLD} and @code{GET_STR_DC_THRESHOLD} represent
+the same basic thing, the point where it becomes worth doing a big division to
+cut the input in half.  @code{GET_STR_PRECOMPUTE_THRESHOLD} includes the cost
+of calculating the radix power required, whereas @code{GET_STR_DC_THRESHOLD}
+assumes that's already available, which is the case when recursing.
+
+Since the base case produces digits from least to most significant but they
+want to be stored from most to least, it's necessary to calculate in advance
+how many digits there will be, or at least be sure not to underestimate that.
+For GMP the number of input bits is multiplied by @code{chars_per_bit_exactly}
+from @code{mp_bases}, rounding up.  The result is either correct or one too
+big.
+
+Examining some of the high bits of the input could increase the chance of
+getting the exact number of digits, but an exact result every time would not
+be practical, since in general the difference between numbers 100@dots{} and
+99@dots{} is only in the last few bits and the work to identify 99@dots{}
+might well be almost as much as a full conversion.
+
+The @math{r/b^n} scheme described above for using multiplications to bring out
+digits might be useful for more than a single limb.  Some brief experiments
+with it on the base case when recursing didn't give a noticeable improvement,
+but perhaps that was only due to the implementation.  Something similar would
+work for the sub-quadratic divisions too, though there would be the cost of
+calculating a bigger radix power.
+
+Another possible improvement for the sub-quadratic part would be to arrange
+for radix powers that balanced the sizes of quotient and remainder produced,
+i.e.@: the highest power would be an @m{b^{nk},b^(n*k)} approximately equal to
+@m{\sqrt{t},sqrt(t)}, not restricted to a @math{2^i} factor.  That ought to
+smooth out a graph of times against sizes, but may or may not be a net
+speedup.

+saves multi-precision operations, as per Knuth section 4.4 part E
+(@pxref{References}).  Some special case code is provided for decimal, giving

+
+Above @code{SET_STR_PRECOMPUTE_THRESHOLD} a sub-quadratic algorithm is used.

+and @math{y} are the limbs.  Adjacent limb pairs are combined into quads
+similarly with @m{xb^{2n}+y,x*b^(2n)+y}.  This continues until a single block
+remains, that being the result.
+
+The advantage of this method is that the multiplications for each @math{x} are
+big blocks, allowing Karatsuba and higher algorithms to be used.  But the cost
+of calculating the powers @m{b^{n2^i},b^(n*2^i)} must be overcome.
+@code{SET_STR_PRECOMPUTE_THRESHOLD} usually ends up quite big, around 5000 digits, and on
+some processors much bigger still.
+
+@code{SET_STR_PRECOMPUTE_THRESHOLD} is based on the input digits (and tuned
+for decimal), though it might be better based on a limb count, so as to be
+independent of the base.  But that sort of count isn't used by the base case
+and so would need some sort of initial calculation or estimate.
+
+The main reason @code{SET_STR_PRECOMPUTE_THRESHOLD} is so much bigger than the

+
+For small @math{n}, the odd factor of @math{n!} is computed with the simple

+for calculating isolated @m{F_n,F[n]} or @m{F_n,F[n]},@m{F_{n-1},F[n-1]}
+values efficiently.
+
+For small @math{n}, a table of single limb values in @code{__gmp_fib_table} is
+used.  On a 32-bit limb this goes up to @m{F_{47},F[47]}, or on a 64-bit limb
+up to @m{F_{93},F[93]}.  For convenience the table starts at @m{F_{-1},F[-1]}.
+
+Beyond the table, values are generated with a binary powering algorithm,
+calculating a pair @m{F_n,F[n]} and @m{F_{n-1},F[n-1]} working from high to
+low across the bits of @math{n}.  The formulas used are
+@tex
+$$\eqalign{

+
+F[2k] = F[2k+1] - F[2k-1]
+@end example
+
+@end ifnottex
+At each step, @math{k} is the high @math{b} bits of @math{n}.  If the next bit
+of @math{n} is 0 then @m{F_{2k},F[2k]},@m{F_{2k-1},F[2k-1]} is used, or if
+it's a 1 then @m{F_{2k+1},F[2k+1]},@m{F_{2k},F[2k]} is used, and the process
+repeated until all bits of @math{n} are incorporated.  Notice these formulas
+require just two squares per bit of @math{n}.
+
+It'd be possible to handle the first few @math{n} above the single limb table
+with simple additions, using the defining Fibonacci recurrence @m{F_{k+1} =
+F_k + F_{k-1}, F[k+1]=F[k]+F[k-1]}, but this is not done since it usually
+turns out to be faster for only about 10 or 20 values of @math{n}, and
+including a block of code for just those doesn't seem worthwhile.  If they
+really mattered it'd be better to extend the data table.
+
+Using a table avoids lots of calculations on small numbers, and makes small
+@math{n} go fast.  A bigger table would make more small @math{n} go fast, it's
+just a question of balancing size against desired speed.  For GMP the code is
+kept compact, with the emphasis primarily on a good powering algorithm.

+step of the algorithm can become one multiply instead of two squares.  One of
+the following two formulas is used, according as @math{n} is odd or even.
+@tex
+$$\eqalign{
+  F_{2k}   &= F_k (F_k + 2F_{k-1}) \cr
+  F_{2k+1} &= (2F_k + F_{k-1}) (2F_k - F_{k-1}) + 2(-1)^k
+}$$
+@end tex

+@m{F_{2k+1},F[2k+1]} here is the same as above, just rearranged to be a

+The Mersenne Twister generator is by Matsumoto and Nishimura
+(@pxref{References}).  It has a non-repeating period of @math{2^@W{19937}-1},
+which is a Mersenne prime, hence the name of the generator.  The state is 624
+words of 32-bits each, which is iterated with one XOR and shift for each
+32-bit word generated, making the algorithm very fast.  Randomness properties
+are also very good and this is the default algorithm used by GMP.
+
+@cindex Linear congruential algorithm
+Linear congruential generators are described in many text books, for instance
+Knuth volume 2 (@pxref{References}).  With a modulus @math{M} and parameters
+@math{A} and @math{C}, an integer state @math{S} is iterated by the formula
+@math{S @leftarrow{} A@GMPmultiply{}S+C @bmod{} M}.  At each step the new
+state is a linear function of the previous, mod @math{M}, hence the name of
+the generator.
+
+In GMP only moduli of the form @math{2^N} are supported, and the current
+implementation is not as well optimized as it could be.  Overheads are
+significant when @math{N} is small, and when @math{N} is large clearly the
+multiply at each step will become slow.  This is not a big concern, since the
+Mersenne Twister generator is better in every respect and is therefore
+recommended for all normal applications.
+
+For both generators the current state can be deduced by observing enough
+output and applying some linear algebra (over GF(2) in the case of the
+Mersenne Twister).  This generally means raw output is unsuitable for
+cryptographic applications without further hashing or the like.

+@subsection Assembly Basics
+
+@code{mpn_addmul_1} and @code{mpn_submul_1} are the most important routines
+for overall GMP performance.  All multiplications and divisions come down to
+repeated calls to these.  @code{mpn_add_n}, @code{mpn_sub_n},
+@code{mpn_lshift} and @code{mpn_rshift} are next most important.
+
+On some CPUs assembly versions of the internal functions
+@code{mpn_mul_basecase} and @code{mpn_sqr_basecase} give significant speedups,
+mainly through avoiding function call overheads.  They can also potentially
+make better use of a wide superscalar processor, as can bigger primitives like
+@code{mpn_addmul_2} or @code{mpn_addmul_4}.
+
+The restrictions on overlaps between sources and destinations
+(@pxref{Low-level Functions}) are designed to facilitate a variety of
+implementations.  For example, knowing @code{mpn_add_n} won't have partly
+overlapping sources and destination means reading can be done far ahead of
+writing on superscalar processors, and loops can be vectorized on a vector
+processor, depending on the carry handling.
+
+
+@node Assembly Carry Propagation, Assembly Cache Handling, Assembly Basics, Assembly Coding
+@subsection Carry Propagation
+@cindex Assembly carry propagation
+
+The problem that presents most challenges in GMP is propagating carries from
+one limb to the next.  In functions like @code{mpn_addmul_1} and
+@code{mpn_add_n}, carries are the only dependencies between limb operations.
+
+On processors with carry flags, a straightforward CISC style @code{adc} is
+generally best.  AMD K6 @code{mpn_addmul_1} however is an example of an
+unusual set of circumstances where a branch works out better.
+
+On RISC processors generally an add and compare for overflow is used.  This
+sort of thing can be seen in @file{mpn/generic/aors_n.c}.  Some carry
+propagation schemes require 4 instructions, meaning at least 4 cycles per
+limb, but other schemes may use just 1 or 2.  On wide superscalar processors
+performance may be completely determined by the number of dependent
+instructions between carry-in and carry-out for each limb.
+
+On vector processors good use can be made of the fact that a carry bit only
+very rarely propagates more than one limb.  When adding a single bit to a
+limb, there's only a carry out if that limb was @code{0xFF@dots{}FF} which on
+random data will be only 1 in @m{2\GMPraise{@code{mp\_bits\_per\_limb}},
+2^mp_bits_per_limb}.  @file{mpn/cray/add_n.c} is an example of this, it adds
+all limbs in parallel, adds one set of carry bits in parallel and then only
+rarely needs to fall through to a loop propagating further carries.
+
+On the x86s, GCC (as of version 2.95.2) doesn't generate particularly good code
+for the RISC style idioms that are necessary to handle carry bits in
+C@.  Often conditional jumps are generated where @code{adc} or @code{sbb} forms
+would be better.  And so unfortunately almost any loop involving carry bits
+needs to be coded in assembly for best results.
+
+
+@node Assembly Cache Handling, Assembly Functional Units, Assembly Carry Propagation, Assembly Coding
+@subsection Cache Handling
+@cindex Assembly cache handling
+
+GMP aims to perform well both on operands that fit entirely in L1 cache and
+those which don't.
+
+Basic routines like @code{mpn_add_n} or @code{mpn_lshift} are often used on
+large operands, so L2 and main memory performance is important for them.
+@code{mpn_mul_1} and @code{mpn_addmul_1} are mostly used for multiply and
+square basecases, so L1 performance matters most for them, unless assembly
+versions of @code{mpn_mul_basecase} and @code{mpn_sqr_basecase} exist, in
+which case the remaining uses are mostly for larger operands.
+
+For L2 or main memory operands, memory access times will almost certainly be
+more than the calculation time.  The aim therefore is to maximize memory
+throughput, by starting a load of the next cache line while processing the
+contents of the previous one.  Clearly this is only possible if the chip has a
+lock-up free cache or some sort of prefetch instruction.  Most current chips
+have both these features.
+
+Prefetching sources combines well with loop unrolling, since a prefetch can be
+initiated once per unrolled loop (or more than once if the loop covers more
+than one cache line).
+
+On CPUs without write-allocate caches, prefetching destinations will ensure
+individual stores don't go further down the cache hierarchy, limiting
+bandwidth.  Of course for calculations which are slow anyway, like
+@code{mpn_divrem_1}, write-throughs might be fine.
+
+The distance ahead to prefetch will be determined by memory latency versus
+throughput.  The aim of course is to have data arriving continuously, at peak
+throughput.  Some CPUs have limits on the number of fetches or prefetches in
+progress.
+
+If a special prefetch instruction doesn't exist then a plain load can be used,
+but in that case care must be taken not to attempt to read past the end of an
+operand, since that might produce a segmentation violation.
+
+Some CPUs or systems have hardware that detects sequential memory accesses and
+initiates suitable cache movements automatically, making life easy.
+
+
+@node Assembly Functional Units, Assembly Floating Point, Assembly Cache Handling, Assembly Coding
+@subsection Functional Units
+
+When choosing an approach for an assembly loop, consideration is given to
+what operations can execute simultaneously and what throughput can thereby be
+achieved.  In some cases an algorithm can be tweaked to accommodate available
+resources.
+
+Loop control will generally require a counter and pointer updates, costing as
+much as 5 instructions, plus any delays a branch introduces.  CPU addressing
+modes might reduce pointer updates, perhaps by allowing just one updating
+pointer and others expressed as offsets from it, or on CISC chips with all
+addressing done with the loop counter as a scaled index.
+
+The final loop control cost can be amortised by processing several limbs in
+each iteration (@pxref{Assembly Loop Unrolling}).  This at least ensures loop
+control isn't a big fraction the work done.
+
+Memory throughput is always a limit.  If perhaps only one load or one store
+can be done per cycle then 3 cycles/limb will the top speed for ``binary''
+operations like @code{mpn_add_n}, and any code achieving that is optimal.
+
+Integer resources can be freed up by having the loop counter in a float
+register, or by pressing the float units into use for some multiplying,
+perhaps doing every second limb on the float side (@pxref{Assembly Floating
+Point}).
+
+Float resources can be freed up by doing carry propagation on the integer
+side, or even by doing integer to float conversions in integers using bit
+twiddling.
+
+
+@node Assembly Floating Point, Assembly SIMD Instructions, Assembly Functional Units, Assembly Coding
+@subsection Floating Point
+@cindex Assembly floating Point
+
+Floating point arithmetic is used in GMP for multiplications on CPUs with poor
+integer multipliers.  It's mostly useful for @code{mpn_mul_1},
+@code{mpn_addmul_1} and @code{mpn_submul_1} on 64-bit machines, and
+@code{mpn_mul_basecase} on both 32-bit and 64-bit machines.
+
+With IEEE 53-bit double precision floats, integer multiplications producing up
+to 53 bits will give exact results.  Breaking a 64@cross{}64 multiplication
+into eight 16@cross{}@math{32@rightarrow{}48} bit pieces is convenient.  With
+some care though six 21@cross{}@math{32@rightarrow{}53} bit products can be
+used, if one of the lower two 21-bit pieces also uses the sign bit.
+
+For the @code{mpn_mul_1} family of functions on a 64-bit machine, the
+invariant single limb is split at the start, into 3 or 4 pieces.  Inside the
+loop, the bignum operand is split into 32-bit pieces.  Fast conversion of
+these unsigned 32-bit pieces to floating point is highly machine-dependent.
+In some cases, reading the data into the integer unit, zero-extending to
+64-bits, then transferring to the floating point unit back via memory is the
+only option.
+
+Converting partial products back to 64-bit limbs is usually best done as a
+signed conversion.  Since all values are smaller than @m{2^{53},2^53}, signed
+and unsigned are the same, but most processors lack unsigned conversions.
+
+@sp 2
+
+Here is a diagram showing 16@cross{}32 bit products for an @code{mpn_mul_1} or
+@code{mpn_addmul_1} with a 64-bit limb.  The single limb operand V is split
+into four 16-bit parts.  The multi-limb operand U is split in the loop into
+two 32-bit parts.

+
+The single-instruction multiple-data support in current microprocessors is
+aimed at signal processing algorithms where each data point can be treated
+more or less independently.  There's generally not much support for
+propagating the sort of carries that arise in GMP.
+
+SIMD multiplications of say four 16@cross{}16 bit multiplies only do as much
+work as one 32@cross{}32 from GMP's point of view, and need some shifts and
+adds besides.  But of course if say the SIMD form is fully pipelined and uses
+less instruction decoding then it may still be worthwhile.
+
+On the x86 chips, MMX has so far found a use in @code{mpn_rshift} and
+@code{mpn_lshift}, and is used in a special case for 16-bit multipliers in the
+P55 @code{mpn_mul_1}.  SSE2 is used for Pentium 4 @code{mpn_mul_1},
+@code{mpn_addmul_1}, and @code{mpn_submul_1}.

+@node Assembly Software Pipelining, Assembly Loop Unrolling, Assembly SIMD Instructions, Assembly Coding
+@subsection Software Pipelining
+@cindex Assembly software pipelining
+
+Software pipelining consists of scheduling instructions around the branch
+point in a loop.  For example a loop might issue a load not for use in the
+present iteration but the next, thereby allowing extra cycles for the data to
+arrive from memory.
+
+Naturally this is wanted only when doing things like loads or multiplies that
+take several cycles to complete, and only where a CPU has multiple functional
+units so that other work can be done in the meantime.
+
+A pipeline with several stages will have a data value in progress at each
+stage and each loop iteration moves them along one stage.  This is like
+juggling.
+
+If the latency of some instruction is greater than the loop time then it will
+be necessary to unroll, so one register has a result ready to use while
+another (or multiple others) are still in progress.  (@pxref{Assembly Loop
+Unrolling}).
+
+
+@node Assembly Loop Unrolling, Assembly Writing Guide, Assembly Software Pipelining, Assembly Coding
+@subsection Loop Unrolling
+@cindex Assembly loop unrolling
+
+Loop unrolling consists of replicating code so that several limbs are
+processed in each loop.  At a minimum this reduces loop overheads by a
+corresponding factor, but it can also allow better register usage, for example
+alternately using one register combination and then another.  Judicious use of
+@command{m4} macros can help avoid lots of duplication in the source code.
+
+Any amount of unrolling can be handled with a loop counter that's decremented
+by @math{N} each time, stopping when the remaining count is less than the
+further @math{N} the loop will process.  Or by subtracting @math{N} at the
+start, the termination condition becomes when the counter @math{C} is less
+than 0 (and the count of remaining limbs is @math{C+N}).
+
+Alternately for a power of 2 unroll the loop count and remainder can be
+established with a shift and mask.  This is convenient if also making a
+computed jump into the middle of a large loop.
+
+The limbs not a multiple of the unrolling can be handled in various ways, for
+example
+
+@itemize @bullet
+@item
+A simple loop at the end (or the start) to process the excess.  Care will be
+wanted that it isn't too much slower than the unrolled part.
+
+@item
+A set of binary tests, for example after an 8-limb unrolling, test for 4 more
+limbs to process, then a further 2 more or not, and finally 1 more or not.
+This will probably take more code space than a simple loop.
+
+@item
+A @code{switch} statement, providing separate code for each possible excess,
+for example an 8-limb unrolling would have separate code for 0 remaining, 1
+remaining, etc, up to 7 remaining.  This might take a lot of code, but may be
+the best way to optimize all cases in combination with a deep pipelined loop.
+
+@item
+A computed jump into the middle of the loop, thus making the first iteration
+handle the excess.  This should make times smoothly increase with size, which
+is attractive, but setups for the jump and adjustments for pointers can be
+tricky and could become quite difficult in combination with deep pipelining.

+@node Assembly Writing Guide,  , Assembly Loop Unrolling, Assembly Coding
+@subsection Writing Guide
+@cindex Assembly writing guide
+
+This is a guide to writing software pipelined loops for processing limb
+vectors in assembly.
+
+First determine the algorithm and which instructions are needed.  Code it
+without unrolling or scheduling, to make sure it works.  On a 3-operand CPU
+try to write each new value to a new register, this will greatly simplify later
+steps.
+
+Then note for each instruction the functional unit and/or issue port
+requirements.  If an instruction can use either of two units, like U0 or U1
+then make a category ``U0/U1''.  Count the total using each unit (or combined
+unit), and count all instructions.
+
+Figure out from those counts the best possible loop time.  The goal will be to
+find a perfect schedule where instruction latencies are completely hidden.
+The total instruction count might be the limiting factor, or perhaps a
+particular functional unit.  It might be possible to tweak the instructions to
+help the limiting factor.
+
+Suppose the loop time is @math{N}, then make @math{N} issue buckets, with the
+final loop branch at the end of the last.  Now fill the buckets with dummy
+instructions using the functional units desired.  Run this to make sure the
+intended speed is reached.
+
+Now replace the dummy instructions with the real instructions from the slow
+but correct loop you started with.  The first will typically be a load
+instruction.  Then the instruction using that value is placed in a bucket an
+appropriate distance down.  Run the loop again, to check it still runs at
+target speed.
+
+Keep placing instructions, frequently measuring the loop.  After a few you
+will need to wrap around from the last bucket back to the top of the loop.  If
+you used the new-register for new-value strategy above then there will be no
+register conflicts.  If not then take care not to clobber something already in
+use.  Changing registers at this time is very error prone.
+
+The loop will overlap two or more of the original loop iterations, and the
+computation of one vector element result will be started in one iteration of
+the new loop, and completed one or several iterations later.
+
+The final step is to create feed-in and wind-down code for the loop.  A good
+way to do this is to make a copy (or copies) of the loop at the start and
+delete those instructions which don't have valid antecedents, and at the end
+replicate and delete those whose results are unwanted (including any further
+loads).
+
+The loop will have a minimum number of limbs loaded and processed, so the
+feed-in code must test if the request size is smaller and skip either to a
+suitable part of the wind-down or to special code for small sizes.

+@code{mpz_t} variables represent integers using sign and magnitude, in space
+dynamically allocated and reallocated.  The fields are as follows.
+
+@table @asis
+@item @code{_mp_size}
+The number of limbs, or the negative of that when representing a negative
+integer.  Zero is represented by @code{_mp_size} set to zero, in which case
+the @code{_mp_d} data is undefined.
+
+@item @code{_mp_d}
+A pointer to an array of limbs which is the magnitude.  These are stored
+``little endian'' as per the @code{mpn} functions, so @code{_mp_d[0]} is the
+least significant limb and @code{_mp_d[ABS(_mp_size)-1]} is the most
+significant.  Whenever @code{_mp_size} is non-zero, the most significant limb
+is non-zero.
+
+Currently there's always at least one readable limb, so for instance
+@code{mpz_get_ui} can fetch @code{_mp_d[0]} unconditionally (though its value
+is undefined if @code{_mp_size} is zero).
+
+@item @code{_mp_alloc}
+@code{_mp_alloc} is the number of limbs currently allocated at @code{_mp_d},
+and normally @code{_mp_alloc >= ABS(_mp_size)}.  When an @code{mpz} routine
+is about to (or might be about to) increase @code{_mp_size}, it checks
+@code{_mp_alloc} to see whether there's enough space, and reallocates if not.
+@code{MPZ_REALLOC} is generally used for this.
+
+@code{mpz_t} variables initialised with the @code{mpz_roinit_n} function or
+the @code{MPZ_ROINIT_N} macro have @code{_mp_alloc = 0} but can have a
+non-zero @code{_mp_size}.  They can only be used as read-only constants. See
+@ref{Integer Special Functions} for details.
+@end table
+
+The various bitwise logical functions like @code{mpz_and} behave as if
+negative values were twos complement.  But sign and magnitude is always used
+internally, and necessary adjustments are made during the calculations.
+Sometimes this isn't pretty, but sign and magnitude are best for other
+routines.
+
+Some internal temporary variables are setup with @code{MPZ_TMP_INIT} and these
+have @code{_mp_d} space obtained from @code{TMP_ALLOC} rather than the memory
+allocation functions.  Care is taken to ensure that these are big enough that
+no reallocation is necessary (since it would have unpredictable consequences).
+
+@code{_mp_size} and @code{_mp_alloc} are @code{int}, although @code{mp_size_t}
+is usually a @code{long}.  This is done to make the fields just 32 bits on
+some 64 bits systems, thereby saving a few bytes of data space but still
+providing plenty of range.

+
+@code{mpq_t} variables represent rationals using an @code{mpz_t} numerator and
+denominator (@pxref{Integer Internals}).
+
+The canonical form adopted is denominator positive (and non-zero), no common
+factors between numerator and denominator, and zero uniquely represented as
+0/1.
+
+It's believed that casting out common factors at each stage of a calculation
+is best in general.  A GCD is an @math{O(N^2)} operation so it's better to do
+a few small ones immediately than to delay and have to do a big one later.
+Knowing the numerator and denominator have no common factors can be used for
+example in @code{mpq_mul} to make only two cross GCDs necessary, not four.
+
+This general approach to common factors is badly sub-optimal in the presence
+of simple factorizations or little prospect for cancellation, but GMP has no
+way to know when this will occur.  As per @ref{Efficiency}, that's left to
+applications.  The @code{mpq_t} framework might still suit, with
+@code{mpq_numref} and @code{mpq_denref} for direct access to the numerator and
+denominator, or of course @code{mpz_t} variables can be used directly.

+The fields are as follows.
+
+@table @asis
+@item @code{_mp_size}
+The number of limbs currently in use, or the negative of that when
+representing a negative value.  Zero is represented by @code{_mp_size} and
+@code{_mp_exp} both set to zero, and in that case the @code{_mp_d} data is
+unused.  (In the future @code{_mp_exp} might be undefined when representing
+zero.)
+
+@item @code{_mp_prec}
+The precision of the mantissa, in limbs.  In any calculation the aim is to
+produce @code{_mp_prec} limbs of result (the most significant being non-zero).
+
+@item @code{_mp_d}
+A pointer to the array of limbs which is the absolute value of the mantissa.
+These are stored ``little endian'' as per the @code{mpn} functions, so
+@code{_mp_d[0]} is the least significant limb and
+@code{_mp_d[ABS(_mp_size)-1]} the most significant.
+
+The most significant limb is always non-zero, but there are no other
+restrictions on its value, in particular the highest 1 bit can be anywhere
+within the limb.
+
+@code{_mp_prec+1} limbs are allocated to @code{_mp_d}, the extra limb being
+for convenience (see below).  There are no reallocations during a calculation,
+only in a change of precision with @code{mpf_set_prec}.
+
+@item @code{_mp_exp}
+The exponent, in limbs, determining the location of the implied radix point.
+Zero means the radix point is just above the most significant limb.  Positive
+values mean a radix point offset towards the lower limbs and hence a value
+@math{@ge{} 1}, as for example in the diagram above.  Negative exponents mean
+a radix point further above the highest limb.
+
+Naturally the exponent can be any value, it doesn't have to fall within the
+limbs as the diagram shows, it can be a long way above or a long way below.
+Limbs other than those included in the @code{@{_mp_d,_mp_size@}} data
+are treated as zero.
+@end table
+
+The @code{_mp_size} and @code{_mp_prec} fields are @code{int}, although the
+@code{mp_size_t} type is usually a @code{long}.  The @code{_mp_exp} field is
+usually @code{long}.  This is done to make some fields just 32 bits on some 64
+bits systems, thereby saving a few bytes of data space but still providing
+plenty of precision and a very large range.
+
+
+@sp 1
+@noindent
+The following various points should be noted.
+
+@table @asis
+@item Low Zeros
+The least significant limbs @code{_mp_d[0]} etc can be zero, though such low
+zeros can always be ignored.  Routines likely to produce low zeros check and
+avoid them to save time in subsequent calculations, but for most routines
+they're quite unlikely and aren't checked.
+
+@item Mantissa Size Range
+The @code{_mp_size} count of limbs in use can be less than @code{_mp_prec} if
+the value can be represented in less.  This means low precision values or
+small integers stored in a high precision @code{mpf_t} can still be operated
+on efficiently.
+
+@code{_mp_size} can also be greater than @code{_mp_prec}.  Firstly a value is
+allowed to use all of the @code{_mp_prec+1} limbs available at @code{_mp_d},
+and secondly when @code{mpf_set_prec_raw} lowers @code{_mp_prec} it leaves
+@code{_mp_size} unchanged and so the size can be arbitrarily bigger than
+@code{_mp_prec}.
+
+@item Rounding
+All rounding is done on limb boundaries.  Calculating @code{_mp_prec} limbs
+with the high non-zero will ensure the application requested minimum precision
+is obtained.
+
+The use of simple ``trunc'' rounding towards zero is efficient, since there's
+no need to examine extra limbs and increment or decrement.
+
+@item Bit Shifts
+Since the exponent is in limbs, there are no bit shifts in basic operations
+like @code{mpf_add} and @code{mpf_mul}.  When differing exponents are
+encountered all that's needed is to adjust pointers to line up the relevant
+limbs.
+
+Of course @code{mpf_mul_2exp} and @code{mpf_div_2exp} will require bit shifts,
+but the choice is between an exponent in limbs which requires shifts there, or
+one in bits which requires them almost everywhere else.
+
+@item Use of @code{_mp_prec+1} Limbs
+The extra limb on @code{_mp_d} (@code{_mp_prec+1} rather than just
+@code{_mp_prec}) helps when an @code{mpf} routine might get a carry from its
+operation.  @code{mpf_add} for instance will do an @code{mpn_add} of
+@code{_mp_prec} limbs.  If there's no carry then that's the result, but if
+there is a carry then it's stored in the extra limb of space and
+@code{_mp_size} becomes @code{_mp_prec+1}.
+
+Whenever @code{_mp_prec+1} limbs are held in a variable, the low limb is not
+needed for the intended precision, only the @code{_mp_prec} high limbs.  But
+zeroing it out or moving the rest down is unnecessary.  Subsequent routines
+reading the value will simply take the high limbs they need, and this will be
+@code{_mp_prec} if their target has that same precision.  This is no more than
+a pointer adjustment, and must be checked anyway since the destination
+precision can be different from the sources.
+
+Copy functions like @code{mpf_set} will retain a full @code{_mp_prec+1} limbs
+if available.  This ensures that a variable which has @code{_mp_size} equal to
+@code{_mp_prec+1} will get its full exact value copied.  Strictly speaking
+this is unnecessary since only @code{_mp_prec} limbs are needed for the
+application's requested precision, but it's considered that an @code{mpf_set}
+from one variable into another of the same precision ought to produce an exact
+copy.
+
+@item Application Precisions
+@code{__GMPF_BITS_TO_PREC} converts an application requested precision to an
+@code{_mp_prec}.  The value in bits is rounded up to a whole limb then an
+extra limb is added since the most significant limb of @code{_mp_d} is only
+non-zero and therefore might contain only one bit.
+
+@code{__GMPF_PREC_TO_BITS} does the reverse conversion, and removes the extra
+limb from @code{_mp_prec} before converting to bits.  The net effect of
+reading back with @code{mpf_get_prec} is simply the precision rounded up to a
+multiple of @code{mp_bits_per_limb}.
+
+Note that the extra limb added here for the high only being non-zero is in
+addition to the extra limb allocated to @code{_mp_d}.  For example with a
+32-bit limb, an application request for 250 bits will be rounded up to 8
+limbs, then an extra added for the high being only non-zero, giving an
+@code{_mp_prec} of 9.  @code{_mp_d} then gets 10 limbs allocated.  Reading
+back with @code{mpf_get_prec} will take @code{_mp_prec} subtract 1 limb and
+multiply by 32, giving 256 bits.
+
+Strictly speaking, the fact the high limb has at least one bit means that a
+float with, say, 3 limbs of 32-bits each will be holding at least 65 bits, but
+for the purposes of @code{mpf_t} it's considered simply to be 64 bits, a nice
+multiple of the limb size.

+
+The size is 4 bytes written most significant byte first, being the number of
+subsequent data bytes, or the twos complement negative of that when a negative
+integer is represented.  The data bytes are the absolute value of the integer,
+written most significant byte first.
+
+The most significant data byte is always non-zero, so the output is the same
+on all systems, irrespective of limb size.
+
+In GMP 1, leading zero bytes were written to pad the data bytes to a multiple
+of the limb size.  @code{mpz_inp_raw} will still accept this, for
+compatibility.
+
+The use of ``big endian'' for both the size and data fields is deliberate, it
+makes the data easy to read in a hex dump of a file.  Unfortunately it also
+means that the limb data must be reversed when reading or writing, so neither
+a big endian nor little endian system can just read and write @code{_mp_d}.

+
+A system of expression templates is used to ensure something like @code{a=b+c}
+turns into a simple call to @code{mpz_add} etc.  For @code{mpf_class}
+the scheme also ensures the precision of the final
+destination is used for any temporaries within a statement like
+@code{f=w*x+y*z}.  These are important features which a naive implementation
+cannot provide.
+
+A simplified description of the scheme follows.  The true scheme is
+complicated by the fact that expressions have different return types.  For
+detailed information, refer to the source code.
+
+To perform an operation, say, addition, we first define a ``function object''
+evaluating it,
+
+@example
+struct __gmp_binary_plus
+@{
+  static void eval(mpf_t f, const mpf_t g, const mpf_t h)
+  @{
+    mpf_add(f, g, h);
+  @}
+@};
+@end example
+
+@noindent
+And an ``additive expression'' object,
+
+@example
+__gmp_expr<__gmp_binary_expr<mpf_class, mpf_class, __gmp_binary_plus> >
+operator+(const mpf_class &f, const mpf_class &g)
+@{
+  return __gmp_expr
+    <__gmp_binary_expr<mpf_class, mpf_class, __gmp_binary_plus> >(f, g);
+@}
+@end example
+
+The seemingly redundant @code{__gmp_expr<__gmp_binary_expr<@dots{}>>} is used to
+encapsulate any possible kind of expression into a single template type.  In
+fact even @code{mpf_class} etc are @code{typedef} specializations of
+@code{__gmp_expr}.
+
+Next we define assignment of @code{__gmp_expr} to @code{mpf_class}.
+
+@example
+template <class T>
+mpf_class & mpf_class::operator=(const __gmp_expr<T> &expr)
+@{
+  expr.eval(this->get_mpf_t(), this->precision());
+  return *this;
+@}
+
+template <class Op>
+void __gmp_expr<__gmp_binary_expr<mpf_class, mpf_class, Op> >::eval
+(mpf_t f, mp_bitcnt_t precision)
+@{
+  Op::eval(f, expr.val1.get_mpf_t(), expr.val2.get_mpf_t());
+@}
+@end example
+
+where @code{expr.val1} and @code{expr.val2} are references to the expression's
+operands (here @code{expr} is the @code{__gmp_binary_expr} stored within the
+@code{__gmp_expr}).
+
+This way, the expression is actually evaluated only at the time of assignment,
+when the required precision (that of @code{f}) is known.  Furthermore the
+target @code{mpf_t} is now available, thus we can call @code{mpf_add} directly
+with @code{f} as the output argument.
+
+Compound expressions are handled by defining operators taking subexpressions
+as their arguments, like this:
+
+@example
+template <class T, class U>
+__gmp_expr
+<__gmp_binary_expr<__gmp_expr<T>, __gmp_expr<U>, __gmp_binary_plus> >
+operator+(const __gmp_expr<T> &expr1, const __gmp_expr<U> &expr2)
+@{
+  return __gmp_expr
+    <__gmp_binary_expr<__gmp_expr<T>, __gmp_expr<U>, __gmp_binary_plus> >
+    (expr1, expr2);
+@}
+@end example
+
+And the corresponding specializations of @code{__gmp_expr::eval}:
+
+@example
+template <class T, class U, class Op>
+void __gmp_expr
+<__gmp_binary_expr<__gmp_expr<T>, __gmp_expr<U>, Op> >::eval
+(mpf_t f, mp_bitcnt_t precision)
+@{
+  // declare two temporaries
+  mpf_class temp1(expr.val1, precision), temp2(expr.val2, precision);
+  Op::eval(f, temp1.get_mpf_t(), temp2.get_mpf_t());
+@}
+@end example
+
+The expression is thus recursively evaluated to any level of complexity and
+all subexpressions are evaluated to the precision of @code{f}.

+
+Torbj@"orn Granlund wrote the original GMP library and is still the main
+developer.  Code not explicitly attributed to others, was contributed by
+Torbj@"orn.  Several other individuals and organizations have contributed
+GMP.  Here is a list in chronological order on first contribution:
+
+Gunnar Sj@"odin and Hans Riesel helped with mathematical problems in early
+versions of the library.
+
+Richard Stallman helped with the interface design and revised the first
+version of this manual.

+FFT multiply code, and the Karatsuba square root code.  He also improved the
+Toom3 code for GMP 4.2.  Paul sparked the development of GMP 2, with his
+comparisons between bignum packages.  The ECMNET project Paul is organizing
+was a driving force behind many of the optimizations in GMP 3.  Paul also
+wrote the new GMP 4.3 nth root code (with Torbj@"orn).
+
+Ken Weber (Kent State University, Universidade Federal do Rio Grande do Sul)
+contributed now defunct versions of @code{mpz_gcd}, @code{mpz_divexact},
+@code{mpn_gcd}, and @code{mpn_bdivmod}, partially supported by CNPq (Brazil)
+grant 301314194-2.
+
+Per Bothner of Cygnus Support helped to set up GMP to use Cygnus' configure.
+He has also made valuable suggestions and tested numerous intermediary
+releases.
+
+Joachim Hollman was involved in the design of the @code{mpf} interface, and in
+the @code{mpz} design revisions for version 2.
+
+Bennet Yee contributed the initial versions of @code{mpz_jacobi} and
+@code{mpz_legendre}.

+improvements for population count.  Robert also wrote highly optimized
+Karatsuba and 3-way Toom multiplication functions for GMP 3, and contributed
+the ARM assembly code.
+
+Torsten Ekedahl of the Mathematical department of Stockholm University provided
+significant inspiration during several phases of the GMP development.  His
+mathematical expertise helped improve several algorithms.

+Linus Nordberg wrote the new configure system based on autoconf and
+implemented the new random functions.
+
+Kevin Ryde worked on a large number of things: optimized x86 code, m4 asm
+macros, parameter tuning, speed measuring, the configure system, function
+inlining, divisibility tests, bit scanning, Jacobi symbols, Fibonacci and Lucas
+number functions, printf and scanf functions, perl interface, demo expression
+parser, the algorithms chapter in the manual, @file{gmpasm-mode.el}, and

+Pedro Gimeno implemented the Mersenne Twister and made other random number
+improvements.
+
+Niels M@"oller wrote the sub-quadratic GCD, extended GCD and jacobi code, the
+quadratic Hensel division code, and (with Torbj@"orn) the new divide and
+conquer division code for GMP 4.3.  Niels also helped implement the new Toom
+multiply code for GMP 4.3 and implemented helper functions to simplify Toom
+evaluations for GMP 5.0.  He wrote the original version of mpn_mulmod_bnm1, and
+he is the main author of the mini-gmp package used for gmp bootstrapping.
+
+Alberto Zanoni and Marco Bodrato suggested the unbalanced multiply strategy,
+and found the optimal strategies for evaluation and interpolation in Toom
+multiplication.
+
+Marco Bodrato helped implement the new Toom multiply code for GMP 4.3 and
+implemented most of the new Toom multiply and squaring code for 5.0.
+He is the main author of the current mpn_mulmod_bnm1, mpn_mullo_n, and
+mpn_sqrlo.  Marco also wrote the functions mpn_invert and mpn_invertappr,
+and improved the speed of integer root extraction.  He is the author of
+mini-mpq, an additional layer to mini-gmp; of most of the combinatorial
+functions and the BPSW primality testing implementation, for both the
+main library and the mini-gmp package.
+
+David Harvey suggested the internal function @code{mpn_bdiv_dbm1}, implementing
+division relevant to Toom multiplication.  He also worked on fast assembly
+sequences, in particular on a fast AMD64 @code{mpn_mul_basecase}. He wrote
+the internal middle product functions @code{mpn_mulmid_basecase},
+@code{mpn_toom42_mulmid}, @code{mpn_mulmid_n} and related helper routines.
+
+Martin Boij wrote @code{mpn_perfect_power_p}.
+
+Marc Glisse improved @file{gmpxx.h}: use fewer temporaries (faster),
+specializations of @code{numeric_limits} and @code{common_type}, C++11
+features (move constructors, explicit bool conversion, UDL), make the
+conversion from @code{mpq_class} to @code{mpz_class} explicit, optimize
+operations where one argument is a small compile-time constant, replace
+some heap allocations by stack allocations.  He also fixed the eofbit
+handling of C++ streams, and removed one division from @file{mpq/aors.c}.
+
+David S Miller wrote assembly code for SPARC T3 and T4.
+
+Mark Sofroniou cleaned up the types of mul_fft.c, letting it work for huge
+operands.
+
+Ulrich Weigand ported GMP to the powerpc64le ABI.

+
+Terms Used In This Document:
+  ISA = Instruction Set Architecture.   The instructions the current
+        processor provides.
+  ABI = Application Binary Interface.  Specifies calling convention,
+        type sizes, etc.
+  AR64 = Arithmetic operations are 64-bit using 64-bit instructions
+	 (E.g., addition, subtraction, load, store, of 64-bit integer types
+	 are done with single instructions, not 32 bits at a time.)
+  Environment = The operating system and compiler.
+
+GMP is a very complex package to build since its speed is very
+sensitive to the ISA and ABI.  For example, if the ISA provides 64-bit
+instructions, it is crucial that GMP is configured to use them.
+
+Most environments that run on a 64-bit ISA provide more than one ABI.
+Typically one of the supported ABI's is a backward compatible 32-bit
+ABI, and one ABI provides 64-bit addressing and `long' (sometimes
+known as LP64).  But a few environments (IRIX, HP-UX) provide
+intermediate ABI's using 32-bit addressing but allow efficient 64-bit
+operations through a `long long' type.  For the latter to be useful to
+GMP, the ABI must allow operations using the native 64-bit
+instructions provided by the ISA, and allow passing of 64-bit
+quantities atomically.
+
+The ABI is typically chosen by means of command line options to the
+compiler tools (gcc, cc, c89, nm, ar, ld, as).  Different environments
+use different defaults, but as of this writing (May 2000) the
+dominating default is to the plain 32-bit ABI in its most arcane form.
+
+The GMP 3.0.x approach was to compile using the ABI that gives the
+best performance.  That places the burden on users to pass special
+options to the compiler when they compile their GMP applications.
+That approach has its advantages and disadvantages.  The main
+advantage is that users don't unknowingly get bad GMP performance.
+The main disadvantage is that users' compiles (actually links) will
+fail unless they pass special compiler options.
+
+** SPARC
+
+System vendors often confuse ABI, ISA, and implementation.  The worst
+case is Solaris, were the unbundled compiler confuses ISA and ABI, and
+the options have very confusing names.
+
+     option		interpretation
+     ======		==============
+cc   -xarch=v8plus	ISA=sparcv9, ABI=V8plus (PTR=32, see below)
+gcc  -mv8plus		ISA=sparcv9, ABI=V8plus (see below)
+cc   -xarch=v9		ISA=sparcv9, ABI=V9 (implying AR=64, PTR=64)
+
+It's hard to believe, but the option v8plus really means ISA=V9!
+
+Solaris releases prior to version 7 running on a V9 CPU fails to
+save/restore the upper 32 bits of the `i' and `l' registers.  The
+`v8plus' option generates code that use as many V9 features as
+possible under such circumstances.
+
+** MIPS
+
+The IRIX 6 compilers gets things right.  They have a clear
+understanding of the differences between ABI and ISA.  The option
+names are descriptive.
+
+     option		interpretation
+     ======		==============
+cc   -n32		ABI=n32 (implying AR=64, PTR=32)
+gcc  -mabi=n32		ABI=n32 (implying AR=64, PTR=32)
+cc   -64		ABI=64 (implying AR=64, PTR=64)
+gcc  -mabi=64		ABI=64 (implying AR=64, PTR=64)
+cc   -mips3		ISA=mips3
+gcc  -mips3		ISA=mips3
+cc   -mips4		ISA=mips4
+gcc  -mips4		ISA=mips4
+
+** HP-PA
+
+HP-UX is somewhat weird, but not as broken as Solaris.
+
+     option		interpretation
+     ======		==============
+cc   +DA2.0		ABI=32bit (implying AR=64, PTR=32)
+cc   +DD64		ABI=64bit (implying AR=64, PTR=64)
+
+Code performing 64-bit arithmetic in the HP-UX 32-bit is not
+compatible with the 64-bit ABI; the former has a calling convention
+that passes/returns 64-bit integer quantities as two 32-bit chunks.
+
+** PowerPC
+
+While the PowerPC ABI's are capable of supporting 64-bit
+registers/operations, the compilers under AIX are similar to Solaris'
+cc in that they don't currently provide any 32-bit addressing with
+64-bit arithmetic.
+
+     option			interpretation
+     ======			==============
+cc   -q64			ABI=64bit (implying AR=64, PTR=64)
+gcc  -maix64 -mpowerpc64	ABI=64bit (implying AR=64, PTR=64)

+
+<ul>
+<li> <strong>Faster multiplication</strong>
+
+  <ol>
+
+    <li> Work on the algorithm selection code for unbalanced multiplication.
+
+    <li> Implement an FFT variant computing the coefficients mod m different
+	 limb size primes of the form l*2^k+1. i.e., compute m separate FFTs.
+	 The wanted coefficients will at the end be found by lifting with CRT
+	 (Chinese Remainder Theorem).  If we let m = 3, i.e., use 3 primes, we
+	 can split the operands into coefficients at limb boundaries, and if
+	 our machine uses b-bit limbs, we can multiply numbers with close to
+	 2^b limbs without coefficient overflow.  For smaller multiplication,
+	 we might perhaps let m = 1, and instead of splitting our operands at
+	 limb boundaries, split them in much smaller pieces.  We might also use
+	 4 or more primes, and split operands into bigger than b-bit chunks.
+	 By using more primes, the gain in shorter transform length, but lose
+	 in having to do more FFTs, but that is a slight total save.  We then
+	 lose in more expensive CRT. <br><br>
+
+	 <p> [We now have two implementations of this algorithm, one by Tommy
+	 Färnqvist and one by Niels Möller.]
+
+    <li> Work on short products.  Our mullo and mulmid are probably K, but we
+         lack mulhi.
+
+  </ol>
+
+  <p> Another possibility would be an optimized cube.  In the basecase that
+      should definitely be able to save cross-products in a similar fashion to
+      squaring, but some investigation might be needed for how best to adapt
+      the higher-order algorithms.  Not sure whether cubing or further small
+      powers have any particularly important uses though.
+
+
+<li> <strong>Assembly routines</strong>
+
+  <p> Write new and improve existing assembly routines.  The tests/devel
+      programs and the tune/speed.c and tune/many.pl programs are useful for
+      testing and timing the routines you write.  See the README files in those
+      directories for more information.
+
+  <p> Please make sure your new routines are fast for these three situations:
+      <ol>
+	<li> Small operands of less than, say, 10 limbs.
+	<li> Medium size operands, that fit into the cache.
+	<li> Huge operands that does not fit into the cache.
+      </ol>
+
+  <p> The most important routines are mpn_addmul_1, mpn_mul_basecase and
+      mpn_sqr_basecase.  The latter two don't exist for all machines, while
+      mpn_addmul_1 exists for almost all machines.
+
+  <p> Standard techniques for these routines are unrolling, software
+      pipelining, and specialization for common operand values.  For machines
+      with poor integer multiplication, it is sometimes possible to remedy the
+      situation using floating-point operations or SIMD operations such as MMX
+      (x86) (x86), SSE (x86), VMX (PowerPC), VIS (Sparc).
+
+  <p> Using floating-point operations is interesting but somewhat tricky.
+      Since IEEE double has 53 bit of mantissa, one has to split the operands
+      in small pieces, so that no intermediates are greater than 2^53.  For
+      32-bit computers, splitting one operand into 16-bit pieces works.  For
+      64-bit machines, one operand can be split into 21-bit pieces and the
+      other into 32-bit pieces.  (A 64-bit operand can be split into just three
+      21-bit pieces if one allows the split operands to be negative!)
+
+
+<li> <strong>Faster sqrt</strong>
+
+  <p> The current code uses divisions, which are reasonably fast, but it'd be
+      possible to use only multiplications by computing 1/sqrt(A) using this
+      iteration:
+      <pre>
+				    2
+		   x   = x  (3 &minus; A x )/2
+		    i+1	  i	    i  </pre>
+      The square root can then be computed like this:
+      <pre>
+		     sqrt(A) = A x
+				  n  </pre>
+  <p> That final multiply might be the full size of the input (though it might
+      only need the high half of that), so there may or may not be any speedup
+      overall.
+
+  <p> We should probably allow a special exponent-like parameter, to speed
+      computations of a precise square root of a small number in mpf and mpfr.
+
+
+<li> <strong>Nth root</strong>
+
+  <p> Improve mpn_rootrem.  The current code is not too bad, but its time
+      complexity is a function of the input, while it is possible to make
+      the <i>average</i> complexity a function of the output.
+
+
+<li> <strong>Fat binaries</strong>
+
+  <p> Add more functions to the set of fat functions.
+
+  <p> The speed of multiplication is today highly dependent on combination
+  functions like <code>addlsh1_n</code>.  A fat binary will never use any such
+  functions, since they are classified as optional.  Ideally, we should use
+  them, but making the current compile-time selections of optional functions
+  become run-time selections for fat binaries.
+
+  <p> If we make fat binaries work really well, we should move away frm tehe
+  current configure scheme (at least by default) and instead include all code
+  always.
+
+
+<li> <strong>Exceptions</strong>
+
+  <p> Some sort of scheme for exceptions handling would be desirable.
+      Presently the only thing documented is that divide by zero in GMP
+      functions provokes a deliberate machine divide by zero (on those systems
+      where such a thing exists at least).  The global <code>gmp_errno</code>
+      is not actually documented, except for the old <code>gmp_randinit</code>
+      function.  Being currently just a plain global means it's not
+      thread-safe.
+
+  <p> The basic choices for exceptions are returning an error code or having a
+      handler function to be called.  The disadvantage of error returns is they
+      have to be checked, leading to tedious and rarely executed code, and
+      strictly speaking such a scheme wouldn't be source or binary compatible.
+      The disadvantage of a handler function is that a <code>longjmp</code> or
+      similar recovery from it may be difficult.  A combination would be
+      possible, for instance by allowing the handler to return an error code.
+
+  <p> Divide-by-zero, sqrt-of-negative, and similar operand range errors can
+      normally be detected at the start of functions, so exception handling
+      would have a clean state.  What's worth considering though is that the
+      GMP function detecting the exception may have been called via some third
+      party library or self contained application module, and hence have
+      various bits of state to be cleaned up above it.  It'd be highly
+      desirable for an exceptions scheme to allow for such cleanups.
+
+  <p> The C++ destructor mechanism could help with cleanups both internally and
+      externally, but being a plain C library we don't want to depend on that.
+
+  <p> A C++ <code>throw</code> might be a good optional extra exceptions
+      mechanism, perhaps under a build option.  For
+      GCC <code>-fexceptions</code> will add the necessary frame information to
+      plain C code, or GMP could be compiled as C++.
+
+  <p> Out-of-memory exceptions are expected to be handled by the
+      <code>mp_set_memory_functions</code> routines, rather than being a
+      prospective part of divide-by-zero etc.  Some similar considerations
+      apply but what differs is that out-of-memory can arise deep within GMP
+      internals.  Even fundamental routines like <code>mpn_add_n</code> and
+      <code>mpn_addmul_1</code> can use temporary memory (for instance on Cray
+      vector systems).  Allowing for an error code return would require an
+      awful lot of checking internally.  Perhaps it'd still be worthwhile, but
+      it'd be a lot of changes and the extra code would probably be rather
+      rarely executed in normal usages.
+
+  <p> A <code>longjmp</code> recovery for out-of-memory will currently, in
+      general, lead to memory leaks and may leave GMP variables operated on in
+      inconsistent states.  Maybe it'd be possible to record recovery
+      information for use by the relevant allocate or reallocate function, but
+      that too would be a lot of changes.
+
+  <p> One scheme for out-of-memory would be to note that all GMP allocations go
+      through the <code>mp_set_memory_functions</code> routines.  So if the
+      application has an intended <code>setjmp</code> recovery point it can
+      record memory activity by GMP and abandon space allocated and variables
+      initialized after that point.  This might be as simple as directing the
+      allocation functions to a separate pool, but in general would have the
+      disadvantage of needing application-level bookkeeping on top of the
+      normal system <code>malloc</code>.  An advantage however is that it needs
+      nothing from GMP itself and on that basis doesn't burden applications not
+      needing recovery.  Note that there's probably some details to be worked
+      out here about reallocs of existing variables, and perhaps about copying
+      or swapping between "permanent" and "temporary" variables.
+
+  <p> Applications desiring a fine-grained error control, for instance a
+      language interpreter, would very possibly not be well served by a scheme
+      requiring <code>longjmp</code>.  Wrapping every GMP function call with a
+      <code>setjmp</code> would be very inconvenient.
+
+  <p> Another option would be to let <code>mpz_t</code> etc hold a sort of NaN,
+      a special value indicating an out-of-memory or other failure.  This would
+      be similar to NaNs in mpfr.  Unfortunately such a scheme could only be
+      used by programs prepared to handle such special values, since for
+      instance a program waiting for some condition to be satisfied could
+      become an infinite loop if it wasn't also watching for NaNs.  The work to
+      implement this would be significant too, lots of checking of inputs and
+      intermediate results.  And if <code>mpn</code> routines were to
+      participate in this (which they would have to internally) a lot of new
+      return values would need to be added, since of course there's no
+      <code>mpz_t</code> etc structure for them to indicate failure in.
+
+  <p> Stack overflow is another possible exception, but perhaps not one that
+      can be easily detected in general.  On i386 GNU/Linux for instance GCC
+      normally doesn't generate stack probes for an <code>alloca</code>, but
+      merely adjusts <code>%esp</code>.  A big enough <code>alloca</code> can
+      miss the stack redzone and hit arbitrary data.  GMP stack usage is
+      normally a function of operand size, which might be enough for some
+      applications to know they'll be safe.  Otherwise a fixed maximum usage
+      can probably be obtained by building with
+      <code>--enable-alloca=malloc-reentrant</code> (or
+      <code>notreentrant</code>).  Arranging the default to be
+      <code>alloca</code> only on blocks up to a certain size and
+      <code>malloc</code> thereafter might be a better approach and would have
+      the advantage of not having calculations limited by available stack.
+
+  <p> Actually recovering from stack overflow is of course another problem.  It
+      might be possible to catch a <code>SIGSEGV</code> in the stack redzone
+      and do something in a <code>sigaltstack</code>, on systems which have
+      that, but recovery might otherwise not be possible.  This is worth
+      bearing in mind because there's no point worrying about tight and careful
+      out-of-memory recovery if an out-of-stack is fatal.
+
+  <p> Operand overflow is another exception to be addressed.  It's easy for
+      instance to ask <code>mpz_pow_ui</code> for a result bigger than an
+      <code>mpz_t</code> can possibly represent.  Currently overflows in limb
+      or byte count calculations will go undetected.  Often they'll still end
+      up asking the memory functions for blocks bigger than available memory,
+      but that's by no means certain and results are unpredictable in general.
+      It'd be desirable to tighten up such size calculations.  Probably only
+      selected routines would need checks, if it's assumed say that no input
+      will be more than half of all memory and hence size additions like say
+      <code>mpz_mul</code> won't overflow.
+
+
+<li> <strong>Performance Tool</strong>
+
+  <p> It'd be nice to have some sort of tool for getting an overview of
+      performance.  Clearly a great many things could be done, but some primary
+      uses would be,
+
+      <ol>
+	<li> Checking speed variations between compilers.
+	<li> Checking relative performance between systems or CPUs.
+      </ol>
+
+  <p> A combination of measuring some fundamental routines and some
+      representative application routines might satisfy these.
+
+  <p> The tune/time.c routines would be the easiest way to get good accurate
+      measurements on lots of different systems.  The high level
+      <code>speed_measure</code> may or may not suit, but the basic
+      <code>speed_starttime</code> and <code>speed_endtime</code> would cover
+      lots of portability and accuracy questions.
+
+
+<li> <strong>Using <code>restrict</code></strong>
+
+  <p> There might be some value in judicious use of C99 style
+      <code>restrict</code> on various pointers, but this would need some
+      careful thought about what it implies for the various operand overlaps
+      permitted in GMP.
+
+  <p> Rumour has it some pre-C99 compilers had <code>restrict</code>, but
+      expressing tighter (or perhaps looser) requirements.  Might be worth
+      investigating that before using <code>restrict</code> unconditionally.
+
+  <p> Loops are presumably where the greatest benefit would be had, by allowing
+      the compiler to advance reads ahead of writes, perhaps as part of loop
+      unrolling.  However critical loops are generally coded in assembler, so
+      there might not be very much to gain.  And on Cray systems the explicit
+      use of <code>_Pragma</code> gives an equivalent effect.
+
+  <p> One thing to note is that Microsoft C headers (on ia64 at least) contain
+      <code>__declspec(restrict)</code>, so a <code>#define</code> of
+      <code>restrict</code> should be avoided.  It might be wisest to setup a
+      <code>gmp_restrict</code>.
+
+
+<li> <strong>Prime Testing</strong>
+
+  <p> GMP is not really a number theory library and probably shouldn't have
+      large amounts of code dedicated to sophisticated prime testing
+      algorithms, but basic things well-implemented would suit.  Tests offering
+      certainty are probably all too big or too slow (or both!) to justify
+      inclusion in the main library.  Demo programs showing some possibilities
+      would be good though.
+
+  <p> The present "repetitions" argument to <code>mpz_probab_prime_p</code> is
+      rather specific to the Miller-Rabin tests of the current implementation.
+      Better would be some sort of parameter asking perhaps for a maximum
+      chance 1/2^x of a probable prime in fact being composite.  If
+      applications follow the advice that the present reps gives 1/4^reps
+      chance then perhaps such a change is unnecessary, but an explicitly
+      described 1/2^x would allow for changes in the implementation or even for
+      new proofs about the theory.
+
+  <p> <code>mpz_probab_prime_p</code> always initializes a new
+      <code>gmp_randstate_t</code> for randomized tests, which unfortunately
+      means it's not really very random and in particular always runs the same
+      tests for a given input.  Perhaps a new interface could accept an rstate
+      to use, so successive tests could increase confidence in the result.
+
+  <p> <code>mpn_mod_34lsub1</code> is an obvious and easy improvement to the
+      trial divisions.  And since the various prime factors are constants, the
+      remainder can be tested with something like
+<pre>
+#define MP_LIMB_DIVISIBLE_7_P(n) \
+  ((n) * MODLIMB_INVERSE_7 &lt;= MP_LIMB_T_MAX/7)
+</pre>
+      Which would help compilers that don't know how to optimize divisions by
+      constants, and is even an improvement on current gcc 3.2 code.  This
+      technique works for any modulus, see Granlund and Montgomery "Division by
+      Invariant Integers" section 9.
+
+  <p> The trial divisions are done with primes generated and grouped at
+      runtime.  This could instead be a table of data, with pre-calculated
+      inverses too.  Storing deltas, ie. amounts to add, rather than actual
+      primes would save space.  <code>udiv_qrnnd_preinv</code> style inverses
+      can be made to exist by adding dummy factors of 2 if necessary.  Some
+      thought needs to be given as to how big such a table should be, based on
+      how much dividing would be profitable for what sort of size inputs.  The
+      data could be shared by the perfect power testing.
+
+  <p> Jason Moxham points out that if a sqrt(-1) mod N exists then any factor
+      of N must be == 1 mod 4, saving half the work in trial dividing.  (If
+      x^2==-1 mod N then for a prime factor p we have x^2==-1 mod p and so the
+      jacobi symbol (-1/p)=1.  But also (-1/p)=(-1)^((p-1)/2), hence must have
+      p==1 mod 4.)  But knowing whether sqrt(-1) mod N exists is not too easy.
+      A strong pseudoprime test can reveal one, so perhaps such a test could be
+      inserted part way though the dividing.
+
+  <p> Jon Grantham "Frobenius Pseudoprimes" (www.pseudoprime.com) describes a
+      quadratic pseudoprime test taking about 3x longer than a plain test, but
+      with only a 1/7710 chance of error (whereas 3 plain Miller-Rabin tests
+      would offer only (1/4)^3 == 1/64).  Such a test needs completely random
+      parameters to satisfy the theory, though single-limb values would run
+      faster.  It's probably best to do at least one plain Miller-Rabin before
+      any quadratic tests, since that can identify composites in less total
+      time.
+
+  <p> Some thought needs to be given to the structure of which tests (trial
+      division, Miller-Rabin, quadratic) and how many are done, based on what
+      sort of inputs we expect, with a view to minimizing average time.
+
+  <p> It might be a good idea to break out subroutines for the various tests,
+      so that an application can combine them in ways it prefers, if sensible
+      defaults in <code>mpz_probab_prime_p</code> don't suit.  In particular
+      this would let applications skip tests it knew would be unprofitable,
+      like trial dividing when an input is already known to have no small
+      factors.
+
+  <p> For small inputs, combinations of theory and explicit search make it
+      relatively easy to offer certainty.  For instance numbers up to 2^32
+      could be handled with a strong pseudoprime test and table lookup.  But
+      it's rather doubtful whether a smallnum prime test belongs in a bignum
+      library.  Perhaps if it had other internal uses.
+
+  <p> An <code>mpz_nthprime</code> might be cute, but is almost certainly
+      impractical for anything but small n.
+
+
+<li> <strong>Intra-Library Calls</strong>
+
+  <p> On various systems, calls within libgmp still go through the PLT, TOC or
+      other mechanism, which makes the code bigger and slower than it needs to
+      be.
+
+  <p> The theory would be to have all GMP intra-library calls resolved directly
+      to the routines in the library.  An application wouldn't be able to
+      replace a routine, the way it can normally, but there seems no good
+      reason to do that, in normal circumstances.
+
+  <p> The <code>visibility</code> attribute in recent gcc is good for this,
+      because it lets gcc omit unnecessary GOT pointer setups or whatever if it
+      finds all calls are local and there's no global data references.
+      Documented entrypoints would be <code>protected</code>, and purely
+      internal things not wanted by test programs or anything can be
+      <code>internal</code>.
+
+  <p> Unfortunately, on i386 it seems <code>protected</code> ends up causing
+      text segment relocations within libgmp.so, meaning the library code can't
+      be shared between processes, defeating the purpose of a shared library.
+      Perhaps this is just a gremlin in binutils (debian packaged
+      2.13.90.0.16-1).
+
+  <p> The linker can be told directly (with a link script, or options) to do
+      the same sort of thing.  This doesn't change the code emitted by gcc of
+      course, but it does mean calls are resolved directly to their targets,
+      avoiding a PLT entry.
+
+  <p> Keeping symbols private to libgmp.so is probably a good thing in general
+      too, to stop anyone even attempting to access them.  But some
+      undocumented things will need or want to be kept visible, for use by
+      mpfr, or the test and tune programs.  Libtool has a standard option for
+      selecting public symbols (used now for libmp).
+
+
+<li> <strong>Math functions for the mpf layer</strong>
+
+  <p> Implement the functions of math.h for the GMP mpf layer!	Check the book
+      "Pi and the AGM" by Borwein and Borwein for ideas how to do this.  These
+      functions are desirable: acos, acosh, asin, asinh, atan, atanh, atan2,
+      cos, cosh, exp, log, log10, pow, sin, sinh, tan, tanh.
+
+  <p> Note that the <a href="http://mpfr.org">mpfr</a> functions already
+  provide these functions, and that we usually recommend new programs to use
+  mpfr instead of mpf.

+
+<h4>Correctness and Completeness</h4>
+<ul>
+<li> <code>_LONG_LONG_LIMB</code> in gmp.h is not namespace clean.  Reported
+     by Patrick Pelissier.
+     <br>
+     We sort of mentioned <code>_LONG_LONG_LIMB</code> in past releases, so
+     need to be careful about changing it.  It used to be a define
+     applications had to set for long long limb systems, but that in
+     particular is no longer relevant now that it's established automatically.
+<li> The various reuse.c tests need to force reallocation by calling
+     <code>_mpz_realloc</code> with a small (1 limb) size.
+<li> One reuse case is missing from mpX/tests/reuse.c:
+     <code>mpz_XXX(a,a,a)</code>.
+<li> Make the string reading functions allow the `0x' prefix when the base is
+     explicitly 16.  They currently only allow that prefix when the base is
+     unspecified (zero).
+<li> <code>mpf_eq</code> is not always correct, when one operand is
+     1000000000... and the other operand is 0111111111..., i.e., extremely
+     close.  There is a special case in <code>mpf_sub</code> for this
+     situation; put similar code in <code>mpf_eq</code>.  [In progress.]
+<li> <code>mpf_eq</code> doesn't implement what gmp.texi specifies.  It should
+     not use just whole limbs, but partial limbs.  [In progress.]
+<li> <code>mpf_set_str</code> doesn't validate it's exponent, for instance
+     garbage 123.456eX789X is accepted (and an exponent 0 used), and overflow
+     of a <code>long</code> is not detected.
+<li> <code>mpf_add</code> doesn't check for a carry from truncated portions of
+     the inputs, and in that respect doesn't implement the "infinite precision
+     followed by truncate" specified in the manual.
+<li> Windows DLLs: tests/mpz/reuse.c and tests/mpf/reuse.c initialize global
+     variables with pointers to <code>mpz_add</code> etc, which doesn't work
+     when those routines are coming from a DLL (because they're effectively
+     function pointer global variables themselves).  Need to rearrange perhaps
+     to a set of calls to a test function rather than iterating over an array.
+<li> <code>mpz_pow_ui</code>: Detect when the result would be more memory than
+     a <code>size_t</code> can represent and raise some suitable exception,
+     probably an alloc call asking for <code>SIZE_T_MAX</code>, and if that
+     somehow succeeds then an <code>abort</code>.  Various size overflows of
+     this kind are not handled gracefully, probably resulting in segvs.
+     <br>
+     In <code>mpz_n_pow_ui</code>, detect when the count of low zero bits
+     exceeds an <code>unsigned long</code>.  There's a (small) chance of this
+     happening but still having enough memory to represent the value.
+     Reported by Winfried Dreckmann in for instance <code>mpz_ui_pow_ui (x,
+     4UL, 1431655766UL)</code>.
+<li> <code>mpf</code>: Detect exponent overflow and raise some exception.
+     It'd be nice to allow the full <code>mp_exp_t</code> range since that's
+     how it's been in the past, but maybe dropping one bit would make it
+     easier to test if e1+e2 goes out of bounds.
+</ul>
+
+
+
+<h4>Machine Independent Optimization</h4>
+<ul>
+<li> <code>mpf_cmp</code>: For better cache locality, don't test for low zero
+     limbs until the high limbs fail to give an ordering.  Reduce code size by
+     turning the three <code>mpn_cmp</code>'s into a single loop stopping when
+     the end of one operand is reached (and then looking for a non-zero in the
+     rest of the other).
+<li> <code>mpf_mul_2exp</code>, <code>mpf_div_2exp</code>: The use of
+     <code>mpn_lshift</code> for any size&lt;=prec means repeated
+     <code>mul_2exp</code> and <code>div_2exp</code> calls accumulate low zero
+     limbs until size==prec+1 is reached.  Those zeros will slow down
+     subsequent operations, especially if the value is otherwise only small.
+     If low bits of the low limb are zero, use <code>mpn_rshift</code> so as
+     to not increase the size.
+<li> <code>mpn_dc_sqrtrem</code>, <code>mpn_sqrtrem2</code>: Don't use
+     <code>mpn_add_1</code> and <code>mpn_sub_1</code> for 1 limb operations,
+     instead <code>ADDC_LIMB</code> and <code>SUBC_LIMB</code>.
+<li> <code>mpn_sqrtrem2</code>: Use plain variables for <code>sp[0]</code> and
+     <code>rp[0]</code> calculations, so the compiler needn't worry about
+     aliasing between <code>sp</code> and <code>rp</code>.
+<li> <code>mpn_sqrtrem</code>: Some work can be saved in the last step when
+     the remainder is not required, as noted in Paul's paper.
+<li> <code>mpq_add</code>, <code>mpq_sub</code>: The gcd fits a single limb
+     with high probability and in this case <code>binvert_limb</code> could
+     be used to calculate the inverse just once for the two exact divisions
+     "op1.den / gcd" and "op2.den / gcd", rather than letting
+     <code>mpn_bdiv_q_1</code> do it each time.  This would require calling
+     <code>mpn_pi1_bdiv_q_1</code>.
+<li> <code>mpn_gcdext</code>: Don't test <code>count_leading_zeros</code> for
+     zero, instead check the high bit of the operand and avoid invoking
+     <code>count_leading_zeros</code>.  This is an optimization on all
+     machines, and significant on machines with slow
+     <code>count_leading_zeros</code>, though it's possible an already
+     normalized operand might not be encountered very often.
+<li> Rewrite <code>umul_ppmm</code> to use floating-point for generating the
+     most significant limb (if <code>GMP_LIMB_BITS</code> &lt= 52 bits).
+     (Peter Montgomery has some ideas on this subject.)
+<li> Improve the default <code>umul_ppmm</code> code in longlong.h: Add partial
+     products with fewer operations.
+<li> Consider inlining <code>mpz_set_ui</code>.  This would be both small and
+     fast, especially for compile-time constants, but would make application
+     binaries depend on having 1 limb allocated to an <code>mpz_t</code>,
+     preventing the "lazy" allocation scheme below.
+<li> Consider inlining <code>mpz_[cft]div_ui</code> and maybe
+     <code>mpz_[cft]div_r_ui</code>.  A <code>__gmp_divide_by_zero</code>
+     would be needed for the divide by zero test, unless that could be left to
+     <code>mpn_mod_1</code> (not sure currently whether all the risc chips
+     provoke the right exception there if using mul-by-inverse).
+<li> Consider inlining: <code>mpz_fits_s*_p</code>.  The setups for
+     <code>LONG_MAX</code> etc would need to go into gmp.h, and on Cray it
+     might, unfortunately, be necessary to forcibly include &lt;limits.h&gt;
+     since there's no apparent way to get <code>SHRT_MAX</code> with an
+     expression (since <code>short</code> and <code>unsigned short</code> can
+     be different sizes).
+<li> <code>mpz_powm</code> and <code>mpz_powm_ui</code> aren't very fast on one
+     or two limb moduli, due to a lot of function call overheads.  These could
+     perhaps be handled as special cases.
+<li> Make sure <code>mpz_powm_ui</code> is never slower than the corresponding
+     computation using <code>mpz_powm</code>.
+<li> <code>mpz_powm</code> REDC should do multiplications by <code>g[]</code>
+     using the division method when they're small, since the REDC form of a
+     small multiplier is normally a full size product.  Probably would need a
+     new tuned parameter to say what size multiplier is "small", as a function
+     of the size of the modulus.
+<li> <code>mpn_gcd</code> might be able to be sped up on small to moderate
+     sizes by improving <code>find_a</code>, possibly just by providing an
+     alternate implementation for CPUs with slowish
+     <code>count_leading_zeros</code>.
+<li> <code>mpf_set_str</code> produces low zero limbs when a string has a
+     fraction but is exactly representable, eg. 0.5 in decimal.  These could be
+     stripped to save work in later operations.
+<li> <code>mpz_and</code>, <code>mpz_ior</code> and <code>mpz_xor</code> should
+     use <code>mpn_and_n</code> etc for the benefit of the small number of
+     targets with native versions of those routines.  Need to be careful not to
+     pass size==0.  Is some code sharing possible between the <code>mpz</code>
+     routines?
+<li> <code>mpf_add</code>: Don't do a copy to avoid overlapping operands
+     unless it's really necessary (currently only sizes are tested, not
+     whether r really is u or v).
+<li> <code>mpf_add</code>: Under the check for v having no effect on the
+     result, perhaps test for r==u and do nothing in that case, rather than
+     currently it looks like an <code>MPN_COPY_INCR</code> will be done to
+     reduce prec+1 limbs to prec.
+<li> <code>mpf_div_ui</code>: Instead of padding with low zeros, call
+     <code>mpn_divrem_1</code> asking for fractional quotient limbs.
+<li> <code>mpf_div_ui</code>: Eliminate <code>TMP_ALLOC</code>.  When r!=u
+     there's no overlap and the division can be called on those operands.
+     When r==u and is prec+1 limbs, then it's an in-place division.  If r==u
+     and not prec+1 limbs, then move the available limbs up to prec+1 and do
+     an in-place there.
+<li> <code>mpf_div_ui</code>: Whether the high quotient limb is zero can be
+     determined by testing the dividend for high&lt;divisor.  When non-zero, the
+     division can be done on prec dividend limbs instead of prec+1.  The result
+     size is also known before the division, so that can be a tail call (once
+     the <code>TMP_ALLOC</code> is eliminated).
+<li> <code>mpn_divrem_2</code> could usefully accept unnormalized divisors and
+     shift the dividend on-the-fly, since this should cost nothing on
+     superscalar processors and avoid the need for temporary copying in
+     <code>mpn_tdiv_qr</code>.
+<li> <code>mpf_sqrt</code>: If r!=u, and if u doesn't need to be padded with
+     zeros, then there's no need for the tp temporary.
+<li> <code>mpq_cmp_ui</code> could form the <code>num1*den2</code> and
+     <code>num2*den1</code> products limb-by-limb from high to low and look at
+     each step for values differing by more than the possible carry bit from
+     the uncalculated portion.
+<li> <code>mpq_cmp</code> could do the same high-to-low progressive multiply
+     and compare.  The benefits of karatsuba and higher multiplication
+     algorithms are lost, but if it's assumed only a few high limbs will be
+     needed to determine an order then that's fine.
+<li> <code>mpn_add_1</code>, <code>mpn_sub_1</code>, <code>mpn_add</code>,
+     <code>mpn_sub</code>: Internally use <code>__GMPN_ADD_1</code> etc
+     instead of the functions, so they get inlined on all compilers, not just
+     gcc and others with <code>inline</code> recognised in gmp.h.
+     <code>__GMPN_ADD_1</code> etc are meant mostly to support application
+     inline <code>mpn_add_1</code> etc and if they don't come out good for
+     internal uses then special forms can be introduced, for instance many
+     internal uses are in-place.  Sometimes a block of code is executed based
+     on the carry-out, rather than using it arithmetically, and those places
+     might want to do their own loops entirely.
+<li> <code>__gmp_extract_double</code> on 64-bit systems could use just one
+     bitfield for the mantissa extraction, not two, when endianness permits.
+     Might depend on the compiler allowing <code>long long</code> bit fields
+     when that's the only actual 64-bit type.
+<li> tal-notreent.c could keep a block of memory permanently allocated.
+     Currently the last nested <code>TMP_FREE</code> releases all memory, so
+     there's an allocate and free every time a top-level function using
+     <code>TMP</code> is called.  Would need
+     <code>mp_set_memory_functions</code> to tell tal-notreent.c to release
+     any cached memory when changing allocation functions though.
+<li> <code>__gmp_tmp_alloc</code> from tal-notreent.c could be partially
+     inlined.  If the current chunk has enough room then a couple of pointers
+     can be updated.  Only if more space is required then a call to some sort
+     of <code>__gmp_tmp_increase</code> would be needed.  The requirement that
+     <code>TMP_ALLOC</code> is an expression might make the implementation a

+<li> <code>__mp_bases</code> has a lot of data for bases which are pretty much
+     never used.  Perhaps the table should just go up to base 16, and have
+     code to generate data above that, if and when required.  Naturally this
+     assumes the code would be smaller than the data saved.
+<li> <code>__mp_bases</code> field <code>big_base_inverted</code> is only used
+     if <code>USE_PREINV_DIVREM_1</code> is true, and could be omitted
+     otherwise, to save space.
+<li> <code>mpz_get_str</code>, <code>mtox</code>: For power-of-2 bases, which
+     are of course fast, it seems a little silly to make a second pass over
+     the <code>mpn_get_str</code> output to convert to ASCII.  Perhaps combine
+     that with the bit extractions.
+<li> <code>mpz_gcdext</code>: If the caller requests only the S cofactor (of
+     A), and A&lt;B, then the code ends up generating the cofactor T (of B) and
+     deriving S from that.  Perhaps it'd be possible to arrange to get S in
+     the first place by calling <code>mpn_gcdext</code> with A+B,B.  This
+     might only be an advantage if A and B are about the same size.
+<li> <code>mpz_n_pow_ui</code> does a good job with small bases and stripping
+     powers of 2, but it's perhaps a bit too complicated for what it gains.
+     The simpler <code>mpn_pow_1</code> is a little faster on small exponents.
+     (Note some of the ugliness in <code>mpz_n_pow_ui</code> is due to
+     supporting <code>mpn_mul_2</code>.)
+     <br>
+     Perhaps the stripping of 2s in <code>mpz_n_pow_ui</code> should be
+     confined to single limb operands for simplicity and since that's where
+     the greatest gain would be.
+     <br>
+     Ideally <code>mpn_pow_1</code> and <code>mpz_n_pow_ui</code> would be
+     merged.  The reason <code>mpz_n_pow_ui</code> writes to an
+     <code>mpz_t</code> is that its callers leave it to make a good estimate
+     of the result size.  Callers of <code>mpn_pow_1</code> already know the
+     size by separate means (<code>mp_bases</code>).
+<li> <code>mpz_invert</code> should call <code>mpn_gcdext</code> directly.

+<h4>Machine Dependent Optimization</h4>
+<ul>
+<li> <code>invert_limb</code> on various processors might benefit from the
+     little Newton iteration done for alpha and ia64.
+<li> Alpha 21264: <code>mpn_addlsh1_n</code> could be implemented with
+     <code>mpn_addmul_1</code>, since that code at 3.5 is a touch faster than
+     a separate <code>lshift</code> and <code>add_n</code> at
+     1.75+2.125=3.875.  Or very likely some specific <code>addlsh1_n</code>
+     code could beat both.
+<li> Alpha 21264: Improve feed-in code for <code>mpn_mul_1</code>,
+     <code>mpn_addmul_1</code>, and <code>mpn_submul_1</code>.
+<li> Alpha 21164: Rewrite <code>mpn_mul_1</code>, <code>mpn_addmul_1</code>,
+     and <code>mpn_submul_1</code> for the 21164.  This should use both integer
+     multiplies and floating-point multiplies.  For the floating-point
+     operations, the single-limb multiplier should be split into three 21-bit
+     chunks, or perhaps even better in four 16-bit chunks.  Probably possible
+     to reach 9 cycles/limb.
+<li> Alpha: GCC 3.4 will introduce <code>__builtin_ctzl</code>,
+     <code>__builtin_clzl</code> and <code>__builtin_popcountl</code> using
+     the corresponding CIX <code>ct</code> instructions, and
+     <code>__builtin_alpha_cmpbge</code>.  These should give GCC more
+     information about scheduling etc than the <code>asm</code> blocks
+     currently used in longlong.h and gmp-impl.h.
+<li> Alpha Unicos: Apparently there's no <code>alloca</code> on this system,
+     making <code>configure</code> choose the slower
+     <code>malloc-reentrant</code> allocation method.  Is there a better way?
+     Maybe variable-length arrays per notes below.
+<li> Alpha Unicos 21164, 21264: <code>.align</code> is not used since it pads
+     with garbage.  Does the code get the intended slotting required for the
+     claimed speeds?  <code>.align</code> at the start of a function would
+     presumably be safe no matter how it pads.
+<li> ARM V5: <code>count_leading_zeros</code> can use the <code>clz</code>
+     instruction.  For GCC 3.4 and up, do this via <code>__builtin_clzl</code>
+     since then gcc knows it's "predicable".
+<li> Itanium: GCC 3.4 introduces <code>__builtin_popcount</code> which can be
+     used instead of an <code>asm</code> block.  The builtin should give gcc
+     more opportunities for scheduling, bundling and predication.
+     <code>__builtin_ctz</code> similarly (it just uses popcount as per
+     current longlong.h).
+<li> UltraSPARC/64: Optimize <code>mpn_mul_1</code>, <code>mpn_addmul_1</code>,
+     for s2 &lt; 2^32 (or perhaps for any zero 16-bit s2 chunk).  Not sure how
+     much this can improve the speed, though, since the symmetry that we rely
+     on is lost.  Perhaps we can just gain cycles when s2 &lt; 2^16, or more
+     accurately, when two 16-bit s2 chunks which are 16 bits apart are zero.
+<li> UltraSPARC/64: Write native <code>mpn_submul_1</code>, analogous to
+     <code>mpn_addmul_1</code>.
+<li> UltraSPARC/64: Write <code>umul_ppmm</code>.  Using four
+     "<code>mulx</code>"s either with an asm block or via the generic C code is
+     about 90 cycles.  Try using fp operations, and also try using karatsuba
+     for just three "<code>mulx</code>"s.
+<li> UltraSPARC/32: Rewrite <code>mpn_lshift</code>, <code>mpn_rshift</code>.
+     Will give 2 cycles/limb.  Trivial modifications of mpn/sparc64 should do.
+<li> UltraSPARC/32: Write special mpn_Xmul_1 loops for s2 &lt; 2^16.
+<li> UltraSPARC/32: Use <code>mulx</code> for <code>umul_ppmm</code> if
+     possible (see commented out code in longlong.h).  This is unlikely to
+     save more than a couple of cycles, so perhaps isn't worth bothering with.
+<li> UltraSPARC/32: On Solaris gcc doesn't give us <code>__sparc_v9__</code>
+     or anything to indicate V9 support when -mcpu=v9 is selected.  See
+     gcc/config/sol2-sld-64.h.  Will need to pass something through from
+     ./configure to select the right code in longlong.h.  (Currently nothing
+     is lost because <code>mulx</code> for multiplying is commented out.)
+<li> UltraSPARC/32: <code>mpn_divexact_1</code> and
+     <code>mpn_modexact_1c_odd</code> can use a 64-bit inverse and take
+     64-bits at a time from the dividend, as per the 32-bit divisor case in
+     mpn/sparc64/mode1o.c.  This must be done in assembler, since the full
+     64-bit registers (<code>%gN</code>) are not available from C.
+<li> UltraSPARC/32: <code>mpn_divexact_by3c</code> can work 64-bits at a time
+     using <code>mulx</code>, in assembler.  This would be the same as for
+     sparc64.
+<li> UltraSPARC: <code>binvert_limb</code> might save a few cycles from
+     masking down to just the useful bits at each point in the calculation,
+     since <code>mulx</code> speed depends on the highest bit set.  Either
+     explicit masks or small types like <code>short</code> and
+     <code>int</code> ought to work.
+<li> Sparc64 HAL R1 <code>popc</code>: This chip reputedly implements
+     <code>popc</code> properly (see gcc sparc.md).  Would need to recognise
+     it as <code>sparchalr1</code> or something in configure / config.sub /
+     config.guess.  <code>popc_limb</code> in gmp-impl.h could use this (per
+     commented out code).  <code>count_trailing_zeros</code> could use it too.
+<li> PA64: Improve <code>mpn_addmul_1</code>, <code>mpn_submul_1</code>, and
+     <code>mpn_mul_1</code>.  The current code runs at 11 cycles/limb.  It
+     should be possible to saturate the cache, which will happen at 8
+     cycles/limb (7.5 for mpn_mul_1).  Write special loops for s2 &lt; 2^32;
+     it should be possible to make them run at about 5 cycles/limb.
+<li> PPC601: See which of the power or powerpc32 code runs better.  Currently
+     the powerpc32 is used, but only because it's the default for
+     <code>powerpc*</code>.
+<li> PPC630: Rewrite <code>mpn_addmul_1</code>, <code>mpn_submul_1</code>, and
+     <code>mpn_mul_1</code>.  Use both integer and floating-point operations,
+     possibly two floating-point and one integer limb per loop.  Split operands
+     into four 16-bit chunks for fast fp operations.  Should easily reach 9
+     cycles/limb (using one int + one fp), but perhaps even 7 cycles/limb
+     (using one int + two fp).
+<li> PPC630: <code>mpn_rshift</code> could do the same sort of unrolled loop
+     as <code>mpn_lshift</code>.  Some judicious use of m4 might let the two
+     share source code, or with a register to control the loop direction
+     perhaps even share object code.
+<li> Implement <code>mpn_mul_basecase</code> and <code>mpn_sqr_basecase</code>
+     for important machines.  Helping the generic sqr_basecase.c with an
+     <code>mpn_sqr_diagonal</code> might be enough for some of the RISCs.
+<li> POWER2/POWER2SC: Schedule <code>mpn_lshift</code>/<code>mpn_rshift</code>.
+     Will bring time from 1.75 to 1.25 cycles/limb.
+<li> X86: Optimize non-MMX <code>mpn_lshift</code> for shifts by 1.  (See
+     Pentium code.)
+<li> X86: Good authority has it that in the past an inline <code>rep
+     movs</code> would upset GCC register allocation for the whole function.
+     Is this still true in GCC 3?  It uses <code>rep movs</code> itself for
+     <code>__builtin_memcpy</code>.  Examine the code for some simple and
+     complex functions to find out.  Inlining <code>rep movs</code> would be
+     desirable, it'd be both smaller and faster.
+<li> Pentium P54: <code>mpn_lshift</code> and <code>mpn_rshift</code> can come
+     down from 6.0 c/l to 5.5 or 5.375 by paying attention to pairing after
+     <code>shrdl</code> and <code>shldl</code>, see mpn/x86/pentium/README.
+<li> Pentium P55 MMX: <code>mpn_lshift</code> and <code>mpn_rshift</code>
+     might benefit from some destination prefetching.
+<li> PentiumPro: <code>mpn_divrem_1</code> might be able to use a
+     mul-by-inverse, hoping for maybe 30 c/l.
+<li> K7: <code>mpn_lshift</code> and <code>mpn_rshift</code> might be able to
+     do something branch-free for unaligned startups, and shaving one insn
+     from the loop with alternative indexing might save a cycle.
+<li> PPC32: Try using fewer registers in the current <code>mpn_lshift</code>.
+     The pipeline is now extremely deep, perhaps unnecessarily deep.
+<li> Fujitsu VPP: Vectorize main functions, perhaps in assembly language.
+<li> Fujitsu VPP: Write <code>mpn_mul_basecase</code> and
+     <code>mpn_sqr_basecase</code>.  This should use a "vertical multiplication
+     method", to avoid carry propagation.  splitting one of the operands in
+     11-bit chunks.
+<li> Pentium: <code>mpn_lshift</code> by 31 should use the special rshift
+     by 1 code, and vice versa <code>mpn_rshift</code> by 31 should use the
+     special lshift by 1.  This would be best as a jump across to the other
+     routine, could let both live in lshift.asm and omit rshift.asm on finding
+     <code>mpn_rshift</code> already provided.
+<li> Cray T3E: Experiment with optimization options.  In particular,
+     -hpipeline3 seems promising.  We should at least up -O to -O2 or -O3.
+<li> Cray: <code>mpn_com</code> and <code>mpn_and_n</code> etc very probably
+     wants a pragma like <code>MPN_COPY_INCR</code>.
+<li> Cray vector systems: <code>mpn_lshift</code>, <code>mpn_rshift</code>,
+     <code>mpn_popcount</code> and <code>mpn_hamdist</code> are nice and small
+     and could be inlined to avoid function calls.
+<li> Cray: Variable length arrays seem to be faster than the tal-notreent.c
+     scheme.  Not sure why, maybe they merely give the compiler more
+     information about aliasing (or the lack thereof).  Would like to modify
+     <code>TMP_ALLOC</code> to use them, or introduce a new scheme.  Memory
+     blocks wanted unconditionally are easy enough, those wanted only
+     sometimes are a problem.  Perhaps a special size calculation to ask for a
+     dummy length 1 when unwanted, or perhaps an inlined subroutine
+     duplicating code under each conditional.  Don't really want to turn
+     everything into a dog's dinner just because Cray don't offer an
+     <code>alloca</code>.
+<li> Cray: <code>mpn_get_str</code> on power-of-2 bases ought to vectorize.
+     Does it?  <code>bits_per_digit</code> and the inner loop over bits in a
+     limb might prevent it.  Perhaps special cases for binary, octal and hex
+     would be worthwhile (very possibly for all processors too).
+<li> S390: <code>BSWAP_LIMB_FETCH</code> looks like it could be done with
+     <code>lrvg</code>, as per glibc sysdeps/s390/s390-64/bits/byteswap.h.
+     This is only for 64-bit mode or something is it, since 32-bit mode has
+     other code?  Also, is it worth using for <code>BSWAP_LIMB</code> too, or
+     would that mean a store and re-fetch?  Presumably that's what comes out
+     in glibc.
+<li> Improve <code>count_leading_zeros</code> for 64-bit machines:
+  <pre>
+	   if ((x &gt&gt 32) == 0) { x &lt&lt= 32; cnt += 32; }
+	   if ((x &gt&gt 48) == 0) { x &lt&lt= 16; cnt += 16; }
+	   ... </pre>
+<li> IRIX 6 MIPSpro compiler has an <code>__inline</code> which could perhaps
+     be used in <code>__GMP_EXTERN_INLINE</code>.  What would be the right way
+     to identify suitable versions of that compiler?
+<li> IRIX <code>cc</code> is rumoured to have an <code>_int_mult_upper</code>
+     (in <code>&lt;intrinsics.h&gt;</code> like Cray), but it didn't seem to
+     exist on some IRIX 6.5 systems tried.  If it does actually exist
+     somewhere it would very likely be an improvement over a function call to
+     umul.asm.
+<li> <code>mpn_get_str</code> final divisions by the base with
+     <code>udiv_qrnd_unnorm</code> could use some sort of multiply-by-inverse
+     on suitable machines.  This ends up happening for decimal by presenting
+     the compiler with a run-time constant, but the same for other bases would
+     be good.  Perhaps use could be made of the fact base&lt;256.
+<li> <code>mpn_umul_ppmm</code>, <code>mpn_udiv_qrnnd</code>: Return a
+     structure like <code>div_t</code> to avoid going through memory, in
+     particular helping RISCs that don't do store-to-load forwarding.  Clearly
+     this is only possible if the ABI returns a structure of two
+     <code>mp_limb_t</code>s in registers.
+     <br>
+     On PowerPC, structures are returned in memory on AIX and Darwin.  In SVR4
+     they're returned in registers, except that draft SVR4 had said memory, so
+     it'd be prudent to check which is done.  We can jam the compiler into the
+     right mode if we know how, since all this is purely internal to libgmp.
+     (gcc has an option, though of course gcc doesn't matter since we use
+     inline asm there.)
+</ul>
+
+<h4>New Functionality</h4>
+<ul>
+<li> Maybe add <code>mpz_crr</code> (Chinese Remainder Reconstruction).
+<li> Let `0b' and `0B' mean binary input everywhere.
+<li> <code>mpz_init</code> and <code>mpq_init</code> could do lazy allocation.
+     Set <code>ALLOC(var)</code> to 0 to indicate nothing allocated, and let
+     <code>_mpz_realloc</code> do the initial alloc.  Set
+     <code>z-&gt;_mp_d</code> to a dummy that <code>mpz_get_ui</code> and
+     similar can unconditionally fetch from.  Niels Möller has had a go at
+     this.
+     <br>
+     The advantages of the lazy scheme would be:
+     <ul>
+     <li> Initial allocate would be the size required for the first value
+          stored, rather than getting 1 limb in <code>mpz_init</code> and then
+          more or less immediately reallocating.
+     <li> <code>mpz_init</code> would only store magic values in the
+          <code>mpz_t</code> fields, and could be inlined.
+     <li> A fixed initializer could even be used by applications, like
+          <code>mpz_t z = MPZ_INITIALIZER;</code>, which might be convenient
+          for globals.
+     </ul>
+     The advantages of the current scheme are:
+     <ul>
+     <li> <code>mpz_set_ui</code> and other similar routines needn't check the
+          size allocated and can just store unconditionally.
+     <li> <code>mpz_set_ui</code> and perhaps others like
+          <code>mpz_tdiv_r_ui</code> and a prospective
+          <code>mpz_set_ull</code> could be inlined.
+     </ul>
+<li> Add <code>mpf_out_raw</code> and <code>mpf_inp_raw</code>.  Make sure
+     format is portable between 32-bit and 64-bit machines, and between
+     little-endian and big-endian machines.  A format which MPFR can use too
+     would be good.
+<li> <code>mpn_and_n</code> ... <code>mpn_copyd</code>: Perhaps make the mpn
+     logops and copys available in gmp.h, either as library functions or
+     inlines, with the availability of library functions instantiated in the
+     generated gmp.h at build time.
+<li> <code>mpz_set_str</code> etc variants taking string lengths rather than
+     null-terminators.
+<li> <code>mpz_andn</code>, <code>mpz_iorn</code>, <code>mpz_nand</code>,
+     <code>mpz_nior</code>, <code>mpz_xnor</code> might be useful additions,
+     if they could share code with the current such functions (which should be
+     possible).
+<li> <code>mpz_and_ui</code> etc might be of use sometimes.  Suggested by
+     Niels Möller.
+<li> <code>mpf_set_str</code> and <code>mpf_inp_str</code> could usefully
+     accept 0x, 0b etc when base==0.  Perhaps the exponent could default to
+     decimal in this case, with a further 0x, 0b etc allowed there.
+     Eg. 0xFFAA@0x5A.  A leading "0" for octal would match the integers, but
+     probably something like "0.123" ought not mean octal.
+<li> <code>GMP_LONG_LONG_LIMB</code> or some such could become a documented
+     feature of gmp.h, so applications could know whether to
+     <code>printf</code> a limb using <code>%lu</code> or <code>%Lu</code>.
+<li> <code>GMP_PRIdMP_LIMB</code> and similar defines following C99
+     &lt;inttypes.h&gt; might be of use to applications printing limbs.  But
+     if <code>GMP_LONG_LONG_LIMB</code> or whatever is added then perhaps this
+     can easily enough be left to applications.
+<li> <code>gmp_printf</code> could accept <code>%b</code> for binary output.
+     It'd be nice if it worked for plain <code>int</code> etc too, not just
+     <code>mpz_t</code> etc.
+<li> <code>gmp_printf</code> in fact could usefully accept an arbitrary base,
+     for both integer and float conversions.  A base either in the format
+     string or as a parameter with <code>*</code> should be allowed.  Maybe
+     <code>&amp;13b</code> (b for base) or something like that.
+<li> <code>gmp_printf</code> could perhaps accept <code>mpq_t</code> for float
+     conversions, eg. <code>"%.4Qf"</code>.  This would be merely for
+     convenience, but still might be useful.  Rounding would be the same as
+     for an <code>mpf_t</code> (ie. currently round-to-nearest, but not
+     actually documented).  Alternately, perhaps a separate
+     <code>mpq_get_str_point</code> or some such might be more use.  Suggested
+     by Pedro Gimeno.
+<li> <code>mpz_rscan0</code> or <code>mpz_revscan0</code> or some such
+     searching towards the low end of an integer might match
+     <code>mpz_scan0</code> nicely.  Likewise for <code>scan1</code>.
+     Suggested by Roberto Bagnara.
+<li> <code>mpz_bit_subset</code> or some such to test whether one integer is a
+     bitwise subset of another might be of use.  Some sort of return value
+     indicating whether it's a proper or non-proper subset would be good and
+     wouldn't cost anything in the implementation.  Suggested by Roberto
+     Bagnara.
+<li> <code>mpf_get_ld</code>, <code>mpf_set_ld</code>: Conversions between
+     <code>mpf_t</code> and <code>long double</code>, suggested by Dan
+     Christensen.  Other <code>long double</code> routines might be desirable
+     too, but <code>mpf</code> would be a start.
+     <br>
+     <code>long double</code> is an ANSI-ism, so everything involving it would
+     need to be suppressed on a K&amp;R compiler.
+     <br>
+     There'd be some work to be done by <code>configure</code> to recognise
+     the format in use, MPFR has a start on this.  Often <code>long
+     double</code> is the same as <code>double</code>, which is easy but
+     pretty pointless.  A single float format detector macro could look at
+     <code>double</code> then <code>long double</code>
+     <br>
+     Sometimes there's a compiler option for the size of a <code>long
+     double</code>, eg. xlc on AIX can use either 64-bit or 128-bit.  It's
+     probably simplest to regard this as a compiler compatibility issue, and
+     leave it to users or sysadmins to ensure application and library code is
+     built the same.
+<li> <code>mpz_sqrt_if_perfect_square</code>: When
+     <code>mpz_perfect_square_p</code> does its tests it calculates a square
+     root and then discards it.  For some applications it might be useful to
+     return that root.  Suggested by Jason Moxham.
+<li> <code>mpz_get_ull</code>, <code>mpz_set_ull</code>,
+     <code>mpz_get_sll</code>, <code>mpz_get_sll</code>: Conversions for
+     <code>long long</code>.  These would aid interoperability, though a
+     mixture of GMP and <code>long long</code> would probably not be too
+     common.  Since <code>long long</code> is not always available (it's in
+     C99 and GCC though), disadvantages of using <code>long long</code> in
+     libgmp.a would be
+     <ul>
+     <li> Library contents vary according to the build compiler.
+     <li> gmp.h would need an ugly <code>#ifdef</code> block to decide if the
+          application compiler could take the <code>long long</code>
+          prototypes.
+     <li> Some sort of <code>LIBGMP_HAS_LONGLONG</code> might be wanted to
+          indicate whether the functions are available.  (Applications using
+          autoconf could probe the library too.)
+     </ul>
+     It'd be possible to defer the need for <code>long long</code> to
+     application compile time, by having something like
+     <code>mpz_set_2ui</code> called with two halves of a <code>long
+     long</code>.  Disadvantages of this would be,
+     <ul>
+     <li> Bigger code in the application, though perhaps not if a <code>long
+          long</code> is normally passed as two halves anyway.
+     <li> <code>mpz_get_ull</code> would be a rather big inline, or would have
+          to be two function calls.
+     <li> <code>mpz_get_sll</code> would be a worse inline, and would put the
+          treatment of <code>-0x10..00</code> into applications (see
+          <code>mpz_get_si</code> correctness above).
+     <li> Although having libgmp.a independent of the build compiler is nice,
+          it sort of sacrifices the capabilities of a good compiler to
+          uniformity with inferior ones.
+     </ul>
+     Plain use of <code>long long</code> is probably the lesser evil, if only
+     because it makes best use of gcc.  In fact perhaps it would suffice to
+     guarantee <code>long long</code> conversions only when using GCC for both
+     application and library.  That would cover free software, and we can
+     worry about selected vendor compilers later.
+     <br>
+     In C++ the situation is probably clearer, we demand fairly recent C++ so
+     <code>long long</code> should be available always.  We'd probably prefer
+     to have the C and C++ the same in respect of <code>long long</code>
+     support, but it would be possible to have it unconditionally in gmpxx.h,
+     by some means or another.
+<li> <code>mpz_strtoz</code> parsing the same as <code>strtol</code>.
+     Suggested by Alexander Kruppa.
+</ul>
+
+
+<h4>Configuration</h4>
+
+<ul>
+<li> Alpha ev7, ev79: Add code to config.guess to detect these.  Believe ev7
+     will be "3-1307" in the current switch, but need to verify that.  (On
+     OSF, current configfsf.guess identifies ev7 using psrinfo, we need to do
+     it ourselves for other systems.)
+<li> Alpha OSF: Libtool (version 1.5) doesn't seem to recognise this system is
+     "pic always" and ends up running gcc twice with the same options.  This
+     is wasteful, but harmless.  Perhaps a newer libtool will be better.
+<li> ARM: <code>umul_ppmm</code> in longlong.h always uses <code>umull</code>,
+     but is that available only for M series chips or some such?  Perhaps it
+     should be configured in some way.
+<li> HPPA: config.guess should recognize 7000, 7100, 7200, and 8x00.
+<li> HPPA: gcc 3.2 introduces a <code>-mschedule=7200</code> etc parameter,
+     which could be driven by an exact hppa cpu type.
+<li> Mips: config.guess should say mipsr3000, mipsr4000, mipsr10000, etc.
+     "hinv -c processor" gives lots of information on Irix.  Standard
+     config.guess appends "el" to indicate endianness, but
+     <code>AC_C_BIGENDIAN</code> seems the best way to handle that for GMP.
+<li> PowerPC: The function descriptor nonsense for AIX is currently driven by
+     <code>*-*-aix*</code>.  It might be more reliable to do some sort of
+     feature test, examining the compiler output perhaps.  It might also be
+     nice to merge the aix.m4 files into powerpc-defs.m4.
+<li> config.m4 is generated only by the configure script, it won't be
+     regenerated by config.status.  Creating it as an <code>AC_OUTPUT</code>
+     would work, but it might upset "make" to have things like <code>L$</code>
+     get into the Makefiles through <code>AC_SUBST</code>.
+     <code>AC_CONFIG_COMMANDS</code> would be the alternative.  With some
+     careful m4 quoting the <code>changequote</code> calls might not be
+     needed, which might free up the order in which things had to be output.
+<li> Automake: Latest automake has a <code>CCAS</code>, <code>CCASFLAGS</code>
+     scheme.  Though we probably wouldn't be using its assembler support we
+     could try to use those variables in compatible ways.
+<li> <code>GMP_LDFLAGS</code> could probably be done with plain
+     <code>LDFLAGS</code> already used by automake for all linking.  But with
+     a bit of luck the next libtool will pass pretty much all
+     <code>CFLAGS</code> through to the compiler when linking, making
+     <code>GMP_LDFLAGS</code> unnecessary.
+<li> mpn/Makeasm.am uses <code>-c</code> and <code>-o</code> together in the
+     .S and .asm rules, but apparently that isn't completely portable (there's
+     an autoconf <code>AC_PROG_CC_C_O</code> test for it).  So far we've not
+     had problems, but perhaps the rules could be rewritten to use "foo.s" as
+     the temporary, or to do a suitable "mv" of the result.  The only danger
+     from using foo.s would be if a compile failed and the temporary foo.s
+     then looked like the primary source.  Hopefully if the
+     <code>SUFFIXES</code> are ordered to have .S and .asm ahead of .s that
+     wouldn't happen.  Might need to check.
+</ul>
+
+
+<h4>Random Numbers</h4>
+<ul>
+<li> <code>_gmp_rand</code> is not particularly fast on the linear
+     congruential algorithm and could stand various improvements.
+     <ul>
+     <li> Make a second seed area within <code>gmp_randstate_t</code> (or
+          <code>_mp_algdata</code> rather) to save some copying.
+     <li> Make a special case for a single limb <code>2exp</code> modulus, to
+          avoid <code>mpn_mul</code> calls.  Perhaps the same for two limbs.
+     <li> Inline the <code>lc</code> code, to avoid a function call and
+          <code>TMP_ALLOC</code> for every chunk.
+     <li> Perhaps the <code>2exp</code> and general LC cases should be split,
+          for clarity (if the general case is retained).
+     </ul>
+<li> <code>gmp_randstate_t</code> used for parameters perhaps should become
+     <code>gmp_randstate_ptr</code> the same as other types.
+<li> Some of the empirical randomness tests could be included in a "make
+     check".  They ought to work everywhere, for a given seed at least.
+</ul>
+
+
+<h4>C++</h4>
+<ul>
+<li> <code>mpz_class(string)</code>, etc: Use the C++ global locale to
+     identify whitespace.
+     <br>
+     <code>mpf_class(string)</code>: Use the C++ global locale decimal point,
+     rather than the C one.
+     <br>
+     Consider making these variant <code>mpz_set_str</code> etc forms
+     available for <code>mpz_t</code> too, not just <code>mpz_class</code>
+     etc.
+<li> <code>mpq_class operator+=</code>: Don't emit an unnecessary
+     <code>mpq_set(q,q)</code> before <code>mpz_addmul</code> etc.
+<li> Put various bits of gmpxx.h into libgmpxx, to avoid excessive inlining.
+     Candidates for this would be,
+     <ul>
+     <li> <code>mpz_class(const char *)</code>, etc: since they're normally
+          not fast anyway, and we can hide the exception <code>throw</code>.
+     <li> <code>mpz_class(string)</code>, etc: to hide the <code>cstr</code>
+          needed to get to the C conversion function.
+     <li> <code>mpz_class string, char*</code> etc constructors: likewise to
+          hide the throws and conversions.
+     <li> <code>mpz_class::get_str</code>, etc: to hide the <code>char*</code>
+          to <code>string</code> conversion and free.  Perhaps
+          <code>mpz_get_str</code> can write directly into a
+          <code>string</code>, to avoid copying.
+          <br>
+          Consider making such <code>string</code> returning variants
+          available for use with plain <code>mpz_t</code> etc too.
+     </ul>
+</ul>
+
+<h4>Miscellaneous</h4>
+<ul>
+<li> <code>mpz_gcdext</code> and <code>mpn_gcdext</code> ought to document
+     what range of values the generated cofactors can take, and preferably
+     ensure the definition uniquely specifies the cofactors for given inputs.
+     A basic extended Euclidean algorithm or multi-step variant leads to
+     |x|&lt;|b| and |y|&lt;|a| or something like that, but there's probably
+     two solutions under just those restrictions.
+<li> demos/factorize.c: use <code>mpz_divisible_ui_p</code> rather than
+     <code>mpz_tdiv_qr_ui</code>.  (Of course dividing multiple primes at a
+     time would be better still.)
+<li> The various test programs use quite a bit of the main
+     <code>libgmp</code>.  This establishes good cross-checks, but it might be
+     better to use simple reference routines where possible.  Where it's not
+     possible some attention could be paid to the order of the tests, so a
+     <code>libgmp</code> routine is only used for tests once it seems to be
+     good.
+<li> <code>MUL_FFT_THRESHOLD</code> etc: the FFT thresholds should allow a
+     return to a previous k at certain sizes.  This arises basically due to
+     the step effect caused by size multiples effectively used for each k.
+     Looking at a graph makes it fairly clear.
+<li> <code>__gmp_doprnt_mpf</code> does a rather unattractive round-to-nearest
+     on the string returned by <code>mpf_get_str</code>.  Perhaps some variant
+     of <code>mpf_get_str</code> could be made which would better suit.
+</ul>
+
+
+<h4>Aids to Development</h4>
+<ul>
+<li> Add <code>ASSERT</code>s at the start of each user-visible mpz/mpq/mpf
+     function to check the validity of each <code>mp?_t</code> parameter, in
+     particular to check they've been <code>mp?_init</code>ed.  This might
+     catch elementary mistakes in user programs.  Care would need to be taken
+     over <code>MPZ_TMP_INIT</code>ed variables used internally.  If nothing
+     else then consistency checks like size&lt;=alloc, ptr not
+     <code>NULL</code> and ptr+size not wrapping around the address space,
+     would be possible.  A more sophisticated scheme could track
+     <code>_mp_d</code> pointers and ensure only a valid one is used.  Such a
+     scheme probably wouldn't be reentrant, not without some help from the
+     system.
+<li> tune/time.c could try to determine at runtime whether
+     <code>getrusage</code> and <code>gettimeofday</code> are reliable.
+     Currently we pretend in configure that the dodgy m68k netbsd 1.4.1
+     <code>getrusage</code> doesn't exist.  If a test might take a long time
+     to run then perhaps cache the result in a file somewhere.
+<li> tune/time.c could choose the default precision based on the
+     <code>speed_unittime</code> determined, independent of the method in use.
+<li> Cray vector systems: CPU frequency could be determined from
+     <code>sysconf(_SC_CLK_TCK)</code>, since it seems to be clock cycle
+     based.  Is this true for all Cray systems?  Would like some documentation
+     or something to confirm.
+</ul>
+
+
+<h4>Documentation</h4>
+<ul>
+<li> <code>mpz_inp_str</code> (etc) doesn't say when it stops reading digits.
+<li> <code>mpn_get_str</code> isn't terribly clear about how many digits it
+     produces.  It'd probably be possible to say at most one leading zero,
+     which is what both it and <code>mpz_get_str</code> currently do.  But
+     want to be careful not to bind ourselves to something that might not suit
+     another implementation.
+<li> <code>va_arg</code> doesn't do the right thing with <code>mpz_t</code>
+     etc directly, but instead needs a pointer type like <code>MP_INT*</code>.
+     It'd be good to show how to do this, but we'd either need to document
+     <code>mpz_ptr</code> and friends, or perhaps fallback on something
+     slightly nasty with <code>void*</code>.
+</ul>
+
+
+<h4>Bright Ideas</h4>
+
+<p> The following may or may not be feasible, and aren't likely to get done in the
+near future, but are at least worth thinking about.
+
+<ul>
+<li> Reorganize longlong.h so that we can inline the operations even for the
+     system compiler.  When there is no such compiler feature, make calls to
+     stub functions.  Write such stub functions for as many machines as
+     possible.
+<li> longlong.h could declare when it's using, or would like to use,
+     <code>mpn_umul_ppmm</code>, and the corresponding umul.asm file could be
+     included in libgmp only in that case, the same as is effectively done for
+     <code>__clz_tab</code>.  Likewise udiv.asm and perhaps cntlz.asm.  This
+     would only be a very small space saving, so perhaps not worth the
+     complexity.
+<li> longlong.h could be built at configure time by concatenating or
+     #including fragments from each directory in the mpn path.  This would
+     select CPU specific macros the same way as CPU specific assembler code.
+     Code used would no longer depend on cpp predefines, and the current
+     nested conditionals could be flattened out.
+<li> <code>mpz_get_si</code> returns 0x80000000 for -0x100000000, whereas it's
+     sort of supposed to return the low 31 (or 63) bits.  But this is
+     undocumented, and perhaps not too important.
+<li> <code>mpz_init_set*</code> and <code>mpz_realloc</code> could allocate
+     say an extra 16 limbs over what's needed, so as to reduce the chance of
+     having to do a reallocate if the <code>mpz_t</code> grows a bit more.
+     This could only be an option, since it'd badly bloat memory usage in
+     applications using many small values.
+<li> <code>mpq</code> functions could perhaps check for numerator or
+     denominator equal to 1, on the assumption that integers or
+     denominator-only values might be expected to occur reasonably often.
+<li> <code>count_trailing_zeros</code> is used on more or less uniformly
+     distributed numbers in a couple of places.  For some CPUs
+     <code>count_trailing_zeros</code> is slow and it's probably worth handling
+     the frequently occurring 0 to 2 trailing zeros cases specially.
+<li> <code>mpf_t</code> might like to let the exponent be undefined when
+     size==0, instead of requiring it 0 as now.  It should be possible to do
+     size==0 tests before paying attention to the exponent.  The advantage is
+     not needing to set exp in the various places a zero result can arise,
+     which avoids some tedium but is otherwise perhaps not too important.
+     Currently <code>mpz_set_f</code> and <code>mpf_cmp_ui</code> depend on
+     exp==0, maybe elsewhere too.
+<li> <code>__gmp_allocate_func</code>: Could use GCC <code>__attribute__
+     ((malloc))</code> on this, though don't know if it'd do much.  GCC 3.0
+     allows that attribute on functions, but not function pointers (see info
+     node "Attribute Syntax"), so would need a new autoconf test.  This can
+     wait until there's a GCC that supports it.
+<li> <code>mpz_add_ui</code> contains two <code>__GMPN_COPY</code>s, one from
+     <code>mpn_add_1</code> and one from <code>mpn_sub_1</code>.  If those two
+     routines were opened up a bit maybe that code could be shared.  When a
+     copy needs to be done there's no carry to append for the add, and if the
+     copy is non-empty no high zero for the sub.
+</ul>
+
+
+<h4>Old and Obsolete Stuff</h4>
+
+<p> The following tasks apply to chips or systems that are old and/or obsolete.
+It's unlikely anything will be done about them unless anyone is actively using
+them.
+
+<ul>
+<li> Sparc32: The integer based udiv_nfp.asm used to be selected by
+     <code>configure --nfp</code> but that option is gone now that autoconf is
+     used.  The file could go somewhere suitable in the mpn search if any
+     chips might benefit from it, though it's possible we don't currently
+     differentiate enough exact cpu types to do this properly.
+<li> VAX D and G format <code>double</code> floats are straightforward and
+     could perhaps be handled directly in <code>__gmp_extract_double</code>
+     and maybe in <code>mpn_get_d</code>, rather than falling back on the
+     generic code.  (Both formats are detected by <code>configure</code>.)
+</ul>

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+/* The aim of this program is to choose either mpn_mod_34lsub1 or mpn_mod_1
+   (plus a PERFSQR_PP modulus), and generate tables indicating quadratic
+   residues and non-residues modulo small factors of that modulus.
+
+   For the usual 32 or 64 bit cases mpn_mod_34lsub1 gets used.  That
+   function exists specifically because 2^24-1 and 2^48-1 have nice sets of
+   prime factors.  For other limb sizes it's considered, but if it doesn't
+   have good factors then mpn_mod_1 will be used instead.
+
+   When mpn_mod_1 is used, the modulus PERFSQR_PP is created from a
+   selection of small primes, chosen to fill PERFSQR_MOD_BITS of a limb,
+   with that bit count chosen so (2*GMP_LIMB_BITS)*2^PERFSQR_MOD_BITS <=
+   GMP_LIMB_MAX, allowing PERFSQR_MOD_IDX in mpn/generic/perfsqr.c to do its
+   calculation within a single limb.
+
+   In either case primes can be combined to make divisors.  The table data
+   then effectively indicates remainders which are quadratic residues mod
+   all the primes.  This sort of combining reduces the number of steps
+   needed after mpn_mod_34lsub1 or mpn_mod_1, saving code size and time.
+   Nothing is gained or lost in terms of detections, the same total fraction
+   of non-residues will be identified.
+
+   Nothing particularly sophisticated is attempted for combining factors to
+   make divisors.  This is probably a kind of knapsack problem so it'd be
+   too hard to attempt anything completely general.  For the usual 32 and 64
+   bit limbs we get a good enough result just pairing the biggest and
+   smallest which fit together, repeatedly.
+
+   Another aim is to get powerful combinations, ie. divisors which identify
+   biggest fraction of non-residues, and have those run first.  Again for
+   the usual 32 and 64 bits it seems good enough just to pair for big
+   divisors then sort according to the resulting fraction of non-residues
+   identified.
+
+   Also in this program, a table sq_res_0x100 of residues modulo 256 is
+   generated.  This simply fills bits into limbs of the appropriate
+   build-time GMP_LIMB_BITS each.

+  Generate tables for fast, division-free trial division for GMP.
+
+  There is one main table, ptab.  It contains primes, multiplied together, and
+  several types of pre-computed inverses.  It refers to tables of the type
+  dtab, via the last two indices.  That table contains the individual primes in
+  the range, except that the primes are not actually included in the table (see
+  the P macro; it sneakingly excludes the primes themselves).  Instead, the
+  dtab tables contains tuples for each prime (modular-inverse, limit) used for
+  divisibility checks.
+
+  This interface is not intended for division of very many primes, since then
+  other algorithms apply.

+/* __GMP_DECLSPEC supports Windows DLL versions of libgmp, and is empty in
+   all other circumstances.
+
+   When compiling objects for libgmp, __GMP_DECLSPEC is an export directive,
+   or when compiling for an application it's an import directive.  The two
+   cases are differentiated by __GMP_WITHIN_GMP defined by the GMP Makefiles
+   (and not defined from an application).
+
+   __GMP_DECLSPEC_XX is similarly used for libgmpxx.  __GMP_WITHIN_GMPXX
+   indicates when building libgmpxx, and in that case libgmpxx functions are
+   exports, but libgmp functions which might get called are imports.
+
+   Libtool DLL_EXPORT define is not used.
+
+   There's no attempt to support GMP built both static and DLL.  Doing so
+   would mean applications would have to tell us which of the two is going
+   to be used when linking, and that seems very tedious and error prone if
+   using GMP by hand, and equally tedious from a package since autoconf and
+   automake don't give much help.
+
+   __GMP_DECLSPEC is required on all documented global functions and
+   variables, the various internals in gmp-impl.h etc can be left unadorned.
+   But internals used by the test programs or speed measuring programs
+   should have __GMP_DECLSPEC, and certainly constants or variables must
+   have it or the wrong address will be resolved.
+
+   In gcc __declspec can go at either the start or end of a prototype.
+
+   In Microsoft C __declspec must go at the start, or after the type like
+   void __declspec(...) *foo()".  There's no __dllexport or anything to
+   guard against someone foolish #defining dllexport.  _export used to be
+   available, but no longer.
+
+   In Borland C _export still exists, but needs to go after the type, like
+   "void _export foo();".  Would have to change the __GMP_DECLSPEC syntax to
+   make use of that.  Probably more trouble than it's worth.  */

+   read-modify-write on CISC CPUs.
+
+   Alternatives:
+
+   Using a pair of pointers instead of indexing would be possible, but gcc
+   isn't able to recognise compile-time src==dst in that case, even when the

+
+   gcc could use "if (__builtin_constant_p(src==dst) && src==dst)" or
+   similar to detect a compile-time src==dst.  This works nicely on gcc
+   2.95.x, it's not good on gcc 3.0 where __builtin_constant_p(p==p) seems
+   to be always false, for a pointer p.  But the current code form seems
+   good enough for src==dst anyway.
+
+   gcc on x86 as usual doesn't give particularly good flags handling for the
+   carry/borrow detection.  It's tempting to want some multi instruction asm
+   blocks to help it, and this was tried, but in truth there's only a few
+   instructions to save and any gain is all too easily lost by register

+/* Results of operators and functions are instances of __gmp_expr<T, U>.
+   T determines the numerical type of the expression: it can be either
+   mpz_t, mpq_t, or mpf_t.  When the arguments of a binary
+   expression have different numerical types, __gmp_resolve_expr is used
+   to determine the "larger" type.
+   U is either __gmp_unary_expr<V, Op> or __gmp_binary_expr<V, W, Op>,
+   where V and W are the arguments' types -- they can in turn be
+   expressions, thus allowing to build compound expressions to any
+   degree of complexity.
+   Op is a function object that must have an eval() method accepting
+   appropriate arguments.
+   Actual evaluation of a __gmp_expr<T, U> object is done when it gets
+   assigned to an mp*_class ("lazy" evaluation): this is done by calling
+   its eval() method. */

+/* Define auxiliary asm macros.
+
+   1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
+   UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
+   word product in HIGH_PROD and LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
+   UDWtype product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a UDWtype, composed by the UWtype integers
+   HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
+   in QUOTIENT and the remainder in REMAINDER.  HIGH_NUMERATOR must be less
+   than DENOMINATOR for correct operation.  If, in addition, the most
+   significant bit of DENOMINATOR must be 1, then the pre-processor symbol
+   UDIV_NEEDS_NORMALIZATION is defined to 1.
+
+   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator).  Like udiv_qrnnd but the numbers are signed.  The quotient
+   is rounded towards 0.
+
+   5) count_leading_zeros(count, x) counts the number of zero-bits from the
+   msb to the first non-zero bit in the UWtype X.  This is the number of
+   steps X needs to be shifted left to set the msb.  Undefined for X == 0,
+   unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
+
+   6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
+   from the least significant end.
+
+   7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two UWtype integers, composed by
+   HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
+   respectively.  The result is placed in HIGH_SUM and LOW_SUM.  Overflow
+   (i.e. carry out) is not stored anywhere, and is lost.
+
+   8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
+   high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
+   composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
+   LOW_SUBTRAHEND_2 respectively.  The result is placed in HIGH_DIFFERENCE
+   and LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
+   and is lost.
+
+   If any of these macros are left undefined for a particular CPU,
+   C macros are used.
+
+
+   Notes:
+
+   For add_ssaaaa the two high and two low addends can both commute, but
+   unfortunately gcc only supports one "%" commutative in each asm block.
+   This has always been so but is only documented in recent versions
+   (eg. pre-release 3.3).  Having two or more "%"s can cause an internal
+   compiler error in certain rare circumstances.
+
+   Apparently it was only the last "%" that was ever actually respected, so
+   the code has been updated to leave just that.  Clearly there's a free
+   choice whether high or low should get it, if there's a reason to favour
+   one over the other.  Also obviously when the constraints on the two
+   operands are identical there's no benefit to the reloader in any "%" at
+   all.
+
+   */
+
+/* The CPUs come in alphabetical order below.
+
+   Please add support for more CPUs here, or improve the current support
+   for the CPUs below!  */
+
+
+/* count_leading_zeros_gcc_clz is count_leading_zeros implemented with gcc
+   3.4 __builtin_clzl or __builtin_clzll, according to our limb size.
+   Similarly count_trailing_zeros_gcc_ctz using __builtin_ctzl or
+   __builtin_ctzll.
+
+   These builtins are only used when we check what code comes out, on some
+   chips they're merely libgcc calls, where we will instead want an inline
+   in that case (either asm or generic C).
+
+   These builtins are better than an asm block of the same insn, since an
+   asm block doesn't give gcc any information about scheduling or resource
+   usage.  We keep an asm block for use on prior versions of gcc though.
+
+   For reference, __builtin_ffs existed in gcc prior to __builtin_clz, but
+   it's not used (for count_leading_zeros) because it generally gives extra
+   code to ensure the result is 0 when the input is 0, which we don't need

+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.

+
+This is "mini-gmp", a small implementation of a subset of GMP's mpn,
+mpz and mpq interfaces.
+
+It is intended for applications which need arithmetic on numbers
+larger than a machine word, but which don't need to handle very large
+numbers very efficiently. Those applications can include a copy of
+mini-gmp to get a GMP-compatible interface with small footprint. One
+can also arrange for optional linking with the real GMP library, using
+mini-gmp as a fallback when for some reason GMP is not available, or
+not desired as a dependency.
+
+The supported GMP subset of the mpn and mpz interfaces is declared in
+mini-gmp.h, and implemented in mini-gmp.c. The implemented
+functions are fully compatible with the corresponding GMP functions,
+as specified in the GMP manual, with a few exceptions:
+
+  mpz_export and mpz_import support only NAILS = 0.
+
+  The REALLOC_FUNC and FREE_FUNC registered with
+  mp_set_memory_functions does not get the correct size of the
+  allocated block in the corresponding argument. mini-gmp always
+  passes zero for these rarely used arguments.
+
+  When mpz_get_str allocates the block, it can be longer than needed.
+
+The performance target for mini-gmp is to be at most 10 times slower
+than the real GMP library, for numbers of size up to a few hundred
+bits. No asymptotically fast algorithms are included in mini-gmp, so
+it will be many orders of magnitude slower than GMP for very large
+numbers.
+
+The supported GMP subset of the mpq layer is declared in mini-mpq.h,
+and implemented in mini-mpq.c.
+
+You should never "install" mini-gmp. Applications can either just
+#include mini-gmp.c (but then, beware that it defines several macros
+and functions outside of the advertised interface), and if needed
+#include mini-mpq.c in a later line (order is important). Or compile
+mini-gmp.c and mini-mpq.c as separate compilation units, and use the
+declarations in mini-gmp.h and mini-mpq.h.
+
+The tests subdirectory contains a testsuite. To use it, you need GMP
+and GNU make. Just run make check in the tests directory. If the
+hard-coded compiler settings are not right, you have to either edit the
+Makefile or pass overriding values on the make command line (e.g.,
+make CC=cc check).
+
+The initial version of mini-gmp was put together by Niels Möller
+<nisse@lysator.liu.se>, with a fair amount of copy-and-paste from the
+GMP sources.

+/* Multiples of GMP_NUMB_BITS in exp simply mean an amount subtracted from
+   EXP(u) to set EXP(r).  The remainder exp%GMP_NUMB_BITS is then a right
+   shift for the limb data.
+
+   If exp%GMP_NUMB_BITS == 0 then there's no shifting, we effectively just
+   do an mpz_set with changed EXP(r).  Like mpz_set we take prec+1 limbs in
+   this case.  Although just prec would suffice, it's nice to have
+   mpf_div_2exp with exp==0 come out the same as mpz_set.
+
+   When shifting we take up to prec many limbs from the input.  Our shift is
+   cy = mpn_rshift (PTR(r)+1, PTR(u)+k, ...), where k is the number of low
+   limbs dropped from u, and the carry out is stored to PTR(r)[0].  We don't
+   try to work extra bits from PTR(u)[k-1] (when k>=1 makes it available)
+   into that low carry limb.  Just prec limbs (with the high non-zero) from
+   the input is enough bits for the application requested precision, no need
+   to do extra work.
+
+   If r==u the shift will have overlapping operands.  When k>=1 (ie. when
+   usize > prec), the overlap is in the style supported by rshift (ie. dst
+   <= src).
+
+   But when r==u and k==0 (ie. usize <= prec), we would have an invalid
+   overlap (mpn_rshift (rp+1, rp, ...)).  In this case we must instead use
+   mpn_lshift (PTR(r), PTR(u), size, NUMB-shift).  An lshift by NUMB-shift
+   bits gives identical data of course, it's just its overlap restrictions
+   which differ.
+
+   In both shift cases, the resulting data is abs_usize+1 limbs.  "adj" is
+   used to add +1 to that size if the high is non-zero (it may of course
+   have become zero by the shifting).  EXP(u) is the exponent just above
+   those abs_usize+1 limbs, so it gets -1+adj, which means -1 if the high is
+   zero, or no change if the high is non-zero.
+
+   Enhancements:
+
+   The way mpn_lshift is used means successive mpf_div_2exp calls on the
+   same operand will accumulate low zero limbs, until prec+1 limbs is
+   reached.  This is wasteful for subsequent operations.  When abs_usize <=
+   prec, we should test the low exp%GMP_NUMB_BITS many bits of PTR(u)[0],
+   ie. those which would be shifted out by an mpn_rshift.  If they're zero
+   then use that mpn_rshift.  */

+
+   Notice this is equivalent to mpz_set_f + mpz_get_ui.
+
+
+   Implementation:
+
+   The limb just above the radix point for us to extract is ptr[size-exp].
+
+   We need to check that the size-exp index falls in our available data

+   involving exp by requiring size>=exp (giving size-exp >= 0) and exp>0
+   (giving size-exp <= size-1).
+
+   Notice if size==0 there's no fetch, since of course size>=exp and exp>0
+   can only be true if size>0.  So there's no special handling for size==0,
+   it comes out as 0 the same as any other time we have no data at our
+   target index.
+
+   For nails, the second limb above the radix point is also required, this

+
+   Again we need to check that size-exp+1 falls in our data range, 0 to

+   size+1>=exp (giving size-exp+1 >= 0) and exp>1 (giving size-exp+1 <=
+   size-1).
+
+   And again if size==0 these second fetch conditions are not satisfied
+   either since size+1>=exp and exp>1 are only true if size>0.
+
+   The code is arranged with exp>0 wrapping the exp>1 test since exp>1 is
+   mis-compiled by alpha gcc prior to version 3.4.  It re-writes it as
+   exp-1>0, which is incorrect when exp==MP_EXP_T_MIN.  By having exp>0

+/* Multiples of GMP_NUMB_BITS in exp simply mean an amount added to EXP(u)
+   to set EXP(r).  The remainder exp%GMP_NUMB_BITS is then a left shift for
+   the limb data.
+
+   If exp%GMP_NUMB_BITS == 0 then there's no shifting, we effectively just
+   do an mpz_set with changed EXP(r).  Like mpz_set we take prec+1 limbs in
+   this case.  Although just prec would suffice, it's nice to have
+   mpf_mul_2exp with exp==0 come out the same as mpz_set.
+
+   When shifting we take up to prec many limbs from the input.  Our shift is
+   cy = mpn_lshift (PTR(r), PTR(u)+k, size, ...), where k is the number of
+   low limbs dropped from u, and the carry out is stored to PTR(r)[size].
+
+   It may be noted that the low limb PTR(r)[0] doesn't incorporate bits from
+   PTR(u)[k-1] (when k>=1 makes that limb available).  Taking just prec
+   limbs from the input (with the high non-zero) is enough bits for the
+   application requested precision, there's no need for extra work.
+
+   If r==u the shift will have overlapping operands.  When k==0 (ie. when
+   usize <= prec), the overlap is supported by lshift (ie. dst == src).
+
+   But when r==u and k>=1 (ie. usize > prec), we would have an invalid
+   overlap (ie. mpn_lshift (rp, rp+k, ...)).  In this case we must instead
+   use mpn_rshift (PTR(r)+1, PTR(u)+k, size, NUMB-shift) with the carry out
+   stored to PTR(r)[0].  An rshift by NUMB-shift bits like this gives
+   identical data, it's just its overlap restrictions which differ.
+
+   Enhancements:
+
+   The way mpn_lshift is used means successive mpf_mul_2exp calls on the
+   same operand will accumulate low zero limbs, until prec+1 limbs is
+   reached.  This is wasteful for subsequent operations.  When abs_usize <=
+   prec, we should test the low exp%GMP_NUMB_BITS many bits of PTR(u)[0],
+   ie. those which would be shifted out by an mpn_rshift.  If they're zero
+   then use that mpn_rshift.  */

+/* The core operation is a multiply of PREC(r) limbs from u by v, producing
+   either PREC(r) or PREC(r)+1 result limbs.  If u is shorter than PREC(r),
+   then we take only as much as it has.  If u is longer we incorporate a
+   carry from the lower limbs.
+
+   If u has just 1 extra limb, then the carry to add is high(up[0]*v).  That
+   is of course what mpn_mul_1 would do if it was called with PREC(r)+1
+   limbs of input.
+
+   If u has more than 1 extra limb, then there can be a further carry bit
+   out of lower uncalculated limbs (the way the low of one product adds to
+   the high of the product below it).  This is of course what an mpn_mul_1
+   would do if it was called with the full u operand.  But we instead work
+   downwards explicitly, until a carry occurs or until a value other than
+   GMP_NUMB_MAX occurs (that being the only value a carry bit can propagate
+   across).
+
+   The carry determination normally requires two umul_ppmm's, only rarely
+   will GMP_NUMB_MAX occur and require further products.
+
+   The carry limb is conveniently added into the mul_1 using mpn_mul_1c when
+   that function exists, otherwise a subsequent mpn_add_1 is needed.
+
+   Clearly when mpn_mul_1c is used the carry must be calculated first.  But
+   this is also the case when add_1 is used, since if r==u and ABSIZ(r) >
+   PREC(r) then the mpn_mul_1 overwrites the low part of the input.
+
+   A reuse r==u with size > prec can occur from a size PREC(r)+1 in the
+   usual way, or it can occur from an mpf_set_prec_raw leaving a bigger
+   sized value.  In both cases we can end up calling mpn_mul_1 with
+   overlapping src and dst regions, but this will be with dst < src and such
+   an overlap is permitted.
+
+   Not done:
+
+   No attempt is made to determine in advance whether the result will be
+   PREC(r) or PREC(r)+1 limbs.  If it's going to be PREC(r)+1 then we could
+   take one less limb from u and generate just PREC(r), that of course
+   satisfying application requested precision.  But any test counting bits
+   or forming the high product would almost certainly take longer than the
+   incremental cost of an extra limb in mpn_mul_1.
+
+   Enhancements:
+
+   Repeated mpf_mul_ui's with an even v will accumulate low zero bits on the
+   result, leaving low zero limbs after a while, which it might be nice to
+   strip to save work in subsequent operations.  Calculating the low limb
+   explicitly would let us direct mpn_mul_1 to put the balance at rp when
+   the low is zero (instead of normally rp+1).  But it's not clear whether
+   this would be worthwhile.  Explicit code for the low limb will probably
+   be slower than having it done in mpn_mul_1, so we need to consider how
+   often a zero will be stripped and how much that's likely to save
+   later.  */

+/* As usual, the aim is to produce PREC(r) limbs of result, with the high
+   limb non-zero.  This is accomplished by applying mpn_sqrtrem to either
+   2*prec or 2*prec-1 limbs, both such sizes resulting in prec limbs.
+
+   The choice between 2*prec or 2*prec-1 limbs is based on the input
+   exponent.  With b=2^GMP_NUMB_BITS the limb base then we can think of
+   effectively taking out a factor b^(2k), for suitable k, to get to an
+   integer input of the desired size ready for mpn_sqrtrem.  It must be an
+   even power taken out, ie. an even number of limbs, so the square root
+   gives factor b^k and the radix point is still on a limb boundary.  So if
+   EXP(r) is even we'll get an even number of input limbs 2*prec, or if
+   EXP(r) is odd we get an odd number 2*prec-1.
+
+   Further limbs below the 2*prec or 2*prec-1 used don't affect the result
+   and are simply truncated.  This can be seen by considering an integer x,
+   with s=floor(sqrt(x)).  s is the unique integer satisfying s^2 <= x <
+   (s+1)^2.  Notice that adding a fraction part to x (ie. some further bits)
+   doesn't change the inequality, s remains the unique solution.  Working
+   suitable factors of 2 into this argument lets it apply to an intended
+   precision at any position for any x, not just the integer binary point.
+
+   If the input is smaller than 2*prec or 2*prec-1, then we just pad with
+   zeros, that of course being our usual interpretation of short inputs.
+   The effect is to extend the root beyond the size of the input (for
+   instance into fractional limbs if u is an integer).  */

+/* As usual the aim is to produce PREC(r) limbs of result with the high limb
+   non-zero.  That high limb will end up floor(sqrt(u)), and limbs below are
+   produced by padding the input with zeros, two for each desired result
+   limb, being 2*(prec-1) for a total 2*prec-1 limbs passed to mpn_sqrtrem.
+   The way mpn_sqrtrem calculates floor(sqrt(x)) ensures the root is correct
+   to the intended accuracy, ie. truncated to prec limbs.
+
+   With nails, u might be two limbs, in which case a total 2*prec limbs is
+   passed to mpn_sqrtrem (still giving a prec limb result).  If uhigh is
+   zero we adjust back to 2*prec-1, since mpn_sqrtrem requires the high
+   non-zero.  2*prec limbs are always allocated, even when uhigh is zero, so
+   the store of uhigh can be done without a conditional.
+
+   u==0 is a special case so the rest of the code can assume the result is
+   non-zero (ie. will have a non-zero high limb on the result).
+
+   Not done:
+
+   No attempt is made to identify perfect squares.  It's considered this can
+   be left to an application if it might occur with any frequency.  As it
+   stands, mpn_sqrtrem does its normal amount of work on a perfect square
+   followed by zero limbs, though of course only an mpn_sqrtrem1 would be
+   actually needed.  We also end up leaving our mpf result with lots of low
+   trailing zeros, slowing down subsequent operations.
+
+   We're not aware of any optimizations that can be made using the fact the
+   input has lots of trailing zeros (apart from the perfect square

+# --tag=CC is necessary since foo.asm is otherwise unknown to libtool.

+# Libtool adds -DPIC when building a shared object and the .asm files look
+# for that.  But it should be noted that the other PIC flags are on occasion
+# important too, in particular FreeBSD 2.2.8 gas 1.92.3 requires -k before
+# it accepts PIC constructs like @GOT, and gcc adds that flag only under

+This directory contains all code for the mpn layer of GMP.
+
+Most subdirectories contain machine-dependent code, written in assembly or C.
+The `generic' subdirectory contains default code, used when there is no
+machine-dependent replacement for a particular machine.
+
+There is one subdirectory for each ISA family.  Note that e.g., 32-bit SPARC
+and 64-bit SPARC are very different ISA's, and thus cannot share any code.
+
+A particular compile will only use code from one subdirectory, and the
+`generic' subdirectory.  The ISA-specific subdirectories contain hierachies of
+directories for various architecture variants and implementations; the
+top-most level contains code that runs correctly on all variants.

+
+ALPHA ASSEMBLY RULES AND REGULATIONS
+
+The `.prologue N' pseudo op marks the end of instruction that needs special
+handling by unwinding.  It also says whether $27 is really needed for computing
+the gp.  The `.mask M' pseudo op says which registers are saved on the stack,
+and at what offset in the frame.
+
+Cray T3 code is very very different...
+
+"$6" / "$f6" etc is the usual syntax for registers, but on Unicos instead "r6"
+/ "f6" is required.  We use the "r6" / "f6" forms, and have m4 defines expand
+them to "$6" or "$f6" where necessary.
+
+"0x" introduces a hex constant in gas and DEC as, but on Unicos "^X" is
+required.  The X() macro accommodates this difference.
+
+"cvttqc" is required by DEC as, "cvttq/c" is required by Unicos, and gas will
+accept either.  We use cvttqc and have an m4 define expand to cvttq/c where
+necessary.
+
+"not" as an alias for "ornot r31, ..." is available in gas and DEC as, but not
+the Unicos assembler.  The full "ornot" must be used.
+
+"unop" is not available in Unicos.  We make an m4 define to the usual "ldq_u
+r31,0(r30)", and in fact use that define on all systems since it comes out the
+same.
+
+"!literal!123" etc explicit relocations as per Tru64 4.0 are apparently not
+available in older alpha assemblers (including gas prior to 2.12), according to
+the GCC manual, so the assembler macro forms must be used (eg. ldgp).
+
+
+
+RELEVANT OPTIMIZATION ISSUES
+
+EV4
+
+1. This chip has very limited store bandwidth.  The on-chip L1 cache is write-
+   through, and a cache line is transferred from the store buffer to the off-
+   chip L2 in as much 15 cycles on most systems.  This delay hurts mpn_add_n,
+   mpn_sub_n, mpn_lshift, and mpn_rshift.
+
+2. Pairing is possible between memory instructions and integer arithmetic
+   instructions.
+
+3. mulq and umulh are documented to have a latency of 23 cycles, but 2 of these
+   cycles are pipelined.  Thus, multiply instructions can be issued at a rate
+   of one each 21st cycle.
+
+EV5
+
+1. The memory bandwidth of this chip is good, both for loads and stores.  The
+   L1 cache can handle two loads or one store per cycle, but two cycles after a
+   store, no ld can issue.
+
+2. mulq has a latency of 12 cycles and an issue rate of 1 each 8th cycle.
+   umulh has a latency of 14 cycles and an issue rate of 1 each 10th cycle.
+   (Note that published documentation gets these numbers slightly wrong.)
+
+3. mpn_add_n.  With 4-fold unrolling, we need 37 instructions, whereof 12
+   are memory operations.  This will take at least
+	ceil(37/2) [dual issue] + 1 [taken branch] = 19 cycles
+   We have 12 memory cycles, plus 4 after-store conflict cycles, or 16 data
+   cache cycles, which should be completely hidden in the 19 issue cycles.
+   The computation is inherently serial, with these dependencies:
+
+	       ldq  ldq
+		 \  /\
+	  (or)   addq |
+	   |\   /   \ |
+	   | addq  cmpult
+	    \  |     |
+	     cmpult  |
+		 \  /
+		  or
+
+   I.e., 3 operations are needed between carry-in and carry-out, making 12
+   cycles the absolute minimum for the 4 limbs.  We could replace the `or' with
+   a cmoveq/cmovne, which could issue one cycle earlier that the `or', but that
+   might waste a cycle on EV4.  The total depth remain unaffected, since cmov
+   has a latency of 2 cycles.
+
+     addq
+     /   \
+   addq  cmpult
+     |      \
+   cmpult -> cmovne
+
+  Montgomery has a slightly different way of computing carry that requires one
+  less instruction, but has depth 4 (instead of the current 3).  Since the code
+  is currently instruction issue bound, Montgomery's idea should save us 1/2
+  cycle per limb, or bring us down to a total of 17 cycles or 4.25 cycles/limb.
+  Unfortunately, this method will not be good for the EV6.
+
+4. addmul_1 and friends: We previously had a scheme for splitting the single-
+   limb operand in 21-bits chunks and the multi-limb operand in 32-bit chunks,
+   and then use FP operations for every 2nd multiply, and integer operations
+   for every 2nd multiply.
+
+   But it seems much better to split the single-limb operand in 16-bit chunks,
+   since we save many integer shifts and adds that way.  See powerpc64/README
+   for some more details.
+
+EV6
+
+Here we have a really parallel pipeline, capable of issuing up to 4 integer
+instructions per cycle.  In actual practice, it is never possible to sustain
+more than 3.5 integer insns/cycle due to rename register shortage.  One integer
+multiply instruction can issue each cycle.  To get optimal speed, we need to
+pretend we are vectorizing the code, i.e., minimize the depth of recurrences.
+
+There are two dependencies to watch out for.  1) Address arithmetic
+dependencies, and 2) carry propagation dependencies.
+
+We can avoid serializing due to address arithmetic by unrolling loops, so that
+addresses don't depend heavily on an index variable.  Avoiding serializing
+because of carry propagation is trickier; the ultimate performance of the code
+will be determined of the number of latency cycles it takes from accepting
+carry-in to a vector point until we can generate carry-out.
+
+Most integer instructions can execute in either the L0, U0, L1, or U1
+pipelines.  Shifts only execute in U0 and U1, and multiply only in U1.
+
+CMOV instructions split into two internal instructions, CMOV1 and CMOV2.  CMOV
+split the mapping process (see pg 2-26 in cmpwrgd.pdf), suggesting the CMOV
+should always be placed as the last instruction of an aligned 4 instruction
+block, or perhaps simply avoided.
+
+Perhaps the most important issue is the latency between the L0/U0 and L1/U1
+clusters; a result obtained on either cluster has an extra cycle of latency for
+consumers in the opposite cluster.  Because of the dynamic nature of the
+implementation, it is hard to predict where an instruction will execute.

+dnl

+dnl  For example,
+dnl
+dnl         ASSERT(r8,
+dnl         `       cmpult r16, r17, r8')
+dnl
+dnl  If the register argument is empty then nothing is tested, the code is
+dnl  just executed.  This can be used for setups required by later ASSERTs.
+dnl  If the code argument is omitted then the register is just tested, with
+dnl  no special setup code.

+dnl  Usage: bigend(`code')
+dnl
+dnl  Emit the given code only for a big-endian system, like Unicos.  This
+dnl  can be used for instance for extra stuff needed by extwl.
+

+
+
+dnl  Usage: bwx_available_p
+dnl
+dnl  Evaluate to 1 if the BWX byte memory instructions are available, or to
+dnl  0 if not.
+dnl
+dnl  Listing the chips which do have BWX means anything we haven't looked at
+dnl  will use safe non-BWX code.  The only targets without BWX currently are
+dnl  plain alpha (ie. ev4) and alphaev5.

+C For ev5 the main loop is 7 cycles plus 1 taken branch bubble, for a total
+C 2.0 c/l.  In general, a pattern like this unrolled to N limbs per loop
+C will be 1.5+2/N c/l.
+C
+C 2 cycles of loop control are unavoidable, for pointer updates and the
+C taken branch bubble, but also since ldq cannot issue two cycles after stq
+C (and with a run of stqs that means neither of two cycles at the end of the
+C loop.
+C
+C The fbeq is forced into the second cycle of the loop using unops, since
+C the first time through it must wait for the cvtqt result.  Once that
+C result is ready (a 1 cycle stall) then both the branch and following loads
+C can issue together.
+C
+C The main loop handles an odd count of limbs, being two limbs loaded before
+C each size test, plus one pipelined around from the previous iteration (or
+C setup in the entry sequence).
+C
+C An even number of limbs is handled by an explicit dst[0]=~src[0] in the
+C entry sequence, and an increment of the pointers.  For an odd size there's
+C no increment and the first store in the loop (r24) is a repeat of dst[0].
+C
+C Note that the load for r24 after the possible pointer increment is done
+C before the explicit store to dst[0], in case src==dst.

+C  * Improve feed-in code, by moving initial mulq earlier; make initial load

+C   Finish cleaning up cy registers r22, r23 (make them use cy0/cy1)
+C   Use multi-pronged feed-in.
+C   Perform additional micro-tuning
+
+C  This code was written in cooperation with ev6 pipeline expert Steve Root.
+
+C  Pair loads and stores where possible
+C  Store pairs oct-aligned where possible (didn't need it here)
+C  Stores are delayed every third cycle
+C  Loads and stores are delayed by fills
+C  U stays still, put code there where possible (note alternation of U1 and U0)
+C  L moves because of loads and stores
+C  Note dampers in L to limit damage
+
+C  This odd-looking optimization expects that were having random bits in our
+C  data, so that a pure zero result is unlikely. so we penalize the unlikely
+C  case to help the common case.

+
+dnl  This code was written in cooperation with ev6 pipeline expert Steve Root.
+
+dnl  The stores can issue a cycle late so we have paired no-op's to 'catch'
+dnl  them, so that further disturbance to the schedule is damped.
+
+dnl  We couldn't pair the loads, because the entangled schedule of the carry's
+dnl  has to happen on one side {0} of the machine.
+
+dnl  This is a great schedule for the d_cache, a poor schedule for the b_cache.
+dnl  The lockup on U0 means that any stall can't be recovered from.  Consider a
+dnl  ldq in L1, say that load gets stalled because it collides with a fill from
+dnl  the b_cache.  On the next cycle, this load gets priority.  If first looks
+dnl  at L0, and goes there.  The instruction we intended for L0 gets to look at
+dnl  L1, which is NOT where we want it.  It either stalls 1, because it can't
+dnl  go in L0, or goes there, and causes a further instruction to stall.
+
+dnl  So for b_cache, we're likely going to want to put one or more cycles back
+dnl  into the code! And, of course, put in lds prefetch for the rp[] operand.
+dnl  At a place where we have an mt followed by a bookkeeping, put the
+dnl  bookkeeping in upper, and the prefetch into lower.
+
+dnl  Note, the ldq's and stq's are at the end of the quadpacks.  Note, we'd
+dnl  like not to have an ldq or an stq to preceded a conditional branch in a
+dnl  quadpack.  The conditional branch moves the retire pointer one cycle
+dnl  later.

+C TODO:
+C  * Optimise.  2.75 c/l should be possible.
+C  * Write a proper mpn_mod_1s_4p_cps.  The code below was compiler generated.
+C  * Optimise feed-in code, starting the sw pipeline in switch code.
+C  * Shorten software pipeline.  The mul instructions are scheduled too far
+C    from their users.  Fixing this will allow us to use fewer registers.
+C  * If we cannot reduce register usage, write perhaps small-n basecase.
+C  * Does this work for PIC?

+
+C This code runs at 2.25 cycles/limb on EV6.
+
+C This code was written in close cooperation with ev6 pipeline expert
+C Steve Root.  Any errors are tege's fault, though.
+
+C Code structure:
+
+C  code for n < 8
+C  code for n > 8	code for (n mod 8)
+C			code for (n div 8)	feed-in code
+C						8-way unrolled loop
+C						wind-down code
+
+C Some notes about unrolled loop:
+C
+C   r1-r8     multiplies and workup
+C   r21-r28   multiplies and workup
+C   r9-r12    loads
+C   r0       -1
+C   r20,r29,r13-r15  scramble
+C
+C   We're doing 7 of the 8 carry propagations with a br fixup code and 1 with a
+C   put-the-carry-into-hi.  The idea is that these branches are very rarely
+C   taken, and since a non-taken branch consumes no resources, that is better
+C   than an addq.
+C
+C   Software pipeline: a load in cycle #09, feeds a mul in cycle #16, feeds an
+C   add NEXT cycle #09 which feeds a store in NEXT cycle #02
+
+C The code could use some further work:
+C   1. Speed up really small multiplies.  The default alpha/mul_1.asm code is
+C      faster than this for size < 3.
+C   2. Improve feed-in code, perhaps with the equivalent of switch(n%8) unless
+C      that is too costly.
+C   3. Consider using 4-way unrolling, even if that runs slower.
+C   4. Reduce register usage.  In particular, try to avoid using r29.

+This directory contains assembly code for nails-enabled 21264.  The code is not
+very well optimized.
+
+For addmul_N, as N grows larger, we could make multiple loads together, then do
+about 3.3 i/c.  10 cycles after the last load, we can increase to 4 i/c.  This
+would surely allow addmul_4 to run at 2 c/l, but the same should be possible
+also for addmul_3 and perhaps even addmul_2.

+C    umulh.
+C  * Use FP loop count and multiple exit points, that would simplify feed-in lp0

+C   Finish cleaning up cy registers r22, r23 (make them use cy0/cy1)
+C   Use multi-pronged feed-in.
+C   Perform additional micro-tuning
+
+C  This code was written in cooperation with ev6 pipeline expert Steve Root.
+
+C  Pair loads and stores where possible
+C  Store pairs oct-aligned where possible (didn't need it here)
+C  Stores are delayed every third cycle
+C  Loads and stores are delayed by fills
+C  U stays still, put code there where possible (note alternation of U1 and U0)
+C  L moves because of loads and stores
+C  Note dampers in L to limit damage
+
+C  This odd-looking optimization expects that were having random bits in our
+C  data, so that a pure zero result is unlikely. so we penalize the unlikely
+C  case to help the common case.

+C
+C In the 1x1 part, the algorithm is to change x,y to abs(x-y),min(x,y) and
+C strip trailing zeros from abs(x-y) to maintain x and y both odd.
+C
+C The trailing zeros are calculated from just x-y, since in twos-complement
+C there's the same number of trailing zeros on d or -d.  This means the cttz
+C runs in parallel with abs(x-y).
+C
+C The loop takes 5 cycles, and at 0.68 iterations per bit for two N-bit
+C operands with this algorithm gives the measured 3.4 c/l.
+C
+C The slottings shown are for SVR4 style systems, Unicos differs in the
+C initial gp setup and the LEA.

+C
+C This code follows the "alternate" code in mpn/generic/mode1o.c,
+C eliminating cbit+climb from the dependent chain.  This leaves,

+C        --    --    --
+C        47    30    15
+C
+C In each case, the load latency, loop control, and extra carry bit handling
+C hide under the multiply latencies.  Those latencies are long enough that
+C we don't need to worry about alignment or pairing to squeeze out
+C performance.
+C
+C For the first limb, some of the loop code is broken out and scheduled back
+C since it can be done earlier.
+C
+C   - The first ldq src[0] is near the start of the routine, for maximum
+C     time from memory.
+C
+C   - The subq y=x-climb can be done without waiting for the inverse.
+C
+C   - The mulq y*inverse is replicated after the final subq for the inverse,
+C     instead of branching to the mulq in the main loop.  On ev4 a branch
+C     there would cost cycles, but we can hide them under the mulq latency.
+C
+C For the last limb, high<divisor is tested and if that's true a subtract
+C and addback is done, as per the main mpn/generic/mode1o.c code.  This is a
+C data-dependent branch, but we're waiting for umulh so any penalty should
+C hide there.  The multiplies saved would be worth the cost anyway.
+C
+C Enhancements:
+C
+C For size==1, a plain division (done bitwise say) might be faster than
+C calculating an inverse, the latter taking about 130 cycles on ev4 or 70 on
+C ev5.  A call to gcc __remqu might be a possibility.

+C Algorithm: We allow ourselves to propagate carry to a product high word
+C without worrying for carry out, since (B-1)^2 = B^2-2B+1 has a high word of
+C B-2, i.e, will not spill.  We propagate carry similarly to a product low word
+C since the problem value B-1 is a quadratic non-residue mod B, but our

+C  * The addlsh1_n code runs well, but is only barely faster than mpn_addmul_1.
+C    The sublsh1_n code could surely be tweaked, its REVCY slows down things
+C    very much.  If two insns are really needed, it might help to separate them
+C    for better micro-parallelism.

+C first and last store, we write using 64-bit aligned addresses.  All shifting
+C is done on 64-bit words in 'extension' registers.
+C
+C It should be possible to read also using 64-bit alignment, by manipulating
+C the shift count for unaligned operands.  Not done, since it does not seem to
+C matter for A9 or A15.
+C
+C This will not work in big-endian mode.
+
+C TODO
+C  * Try using 128-bit operations.  Note that Neon lacks pure 128-bit shifts,
+C    which might make it tricky.
+C  * Clean up and simplify.
+C  * Consider sharing most of the code for lshift and rshift, since the feed-in
+C    code, the loop, and most of the wind-down code are identical.
+C  * Replace the basecase code with code using 'extension' registers.
+C  * Optimise.  It is not clear that this loop insn permutation is optimal for
+C    either A9 or A15.

+C We read 64 bits at a time at 32-bit aligned addresses, and except for the
+C first and last store, we write using 64-bit aligned addresses.  All shifting
+C is done on 64-bit words in 'extension' registers.
+C
+C It should be possible to read also using 64-bit alignment, by manipulating
+C the shift count for unaligned operands.  Not done, since it does not seem to
+C matter for A9 or A15.
+C
+C This will not work in big-endian mode.
+
+C TODO
+C  * Try using 128-bit operations.  Note that Neon lacks pure 128-bit shifts,
+C    which might make it tricky.
+C  * Clean up and simplify.
+C  * Consider sharing most of the code for lshift and rshift, since the feed-in
+C    code, the loop, and most of the wind-down code are identical.
+C  * Replace the basecase code with code using 'extension' registers.
+C  * Optimise.  It is not clear that this loop insn permutation is optimal for
+C    either A9 or A15.

+C TODO
+C  * Align more labels.
+C  * Further tweak counter and updates in outer loops.  (This could save
+C    perhaps 5n cycles).
+C  * Avoid sub-with-lsl in outer loops.  We could keep n up-shifted, then
+C    initialise loop counter i with a right shift.
+C  * Try to use fewer register.  Perhaps coalesce r9 branch target and n_saved.
+C    (This could save 2-3 cycles for n > 4.)
+C  * Optimise sqr_diag_addlsh1 loop.  The current code uses old-style carry
+C    propagation.
+C  * Stop loops earlier suppressing writes of upper-most rp[] values.
+C  * The addmul_2 loops here runs well on all cores, but mul_2 runs poorly
+C    particularly on Cortex-A8.

+C This code uses umlal for adding in the rp[] data, keeping the recurrency path
+C separate from any multiply instructions.  It performs well on A15, at umlal's
+C bandwidth.
+C
+C An A9 variant should perhaps stick to 3-way unrolling, and use ldm and stm
+C for all loads and stores.  Alternatively, it could do 2-way or 4-way, but
+C then alignment aware code will be necessary (adding O(1) bookkeeping
+C overhead).
+C
+C We don't use r12 due to ldrd and strd limitations.

+C This code uses umlal and umaal for adding in the rp[] data, keeping the
+C recurrency path separate from any multiply instructions.  It performs well on
+C A15, but not quite at the multiply bandwidth like the corresponding addmul_1
+C code.
+C
+C We don't use r12 due to ldrd and strd limitations.
+C
+C This loop complements U on the fly,
+C   U' = B^n - 1 - U
+C and then uses that
+C   R - U*v = R + U'*v + v - B^n v

+C    on the tested pipelines, we keep addmul_1 and submul_1 similar.
+C  * We could separate feed-in into 4 blocks, one for each residue (mod 4).

+
+
+dnl  These macros are designed for use with any m4 and have been used on
+dnl  GNU, FreeBSD, NetBSD, OpenBSD and SysV.
+dnl
+dnl  GNU m4 and OpenBSD 2.7 m4 will give filenames and line numbers in error
+dnl  messages.
+dnl
+dnl
+dnl  Macros:
+dnl
+dnl  Most new m4 specific macros have an "m4_" prefix to emphasise they're
+dnl  m4 expansions.  But new defining things like deflit() and defreg() are
+dnl  named like the builtin define(), and forloop() is named following the
+dnl  GNU m4 example on which it's based.
+dnl
+dnl  GNU m4 with the -P option uses "m4_" as a prefix for builtins, but that
+dnl  option isn't going to be used, so there's no conflict or confusion.
+dnl
+dnl
+dnl  Comments in output:
+dnl
+dnl  The m4 comment delimiters are left at # and \n, the normal assembler
+dnl  commenting for most CPUs.  m4 passes comment text through without
+dnl  expanding macros in it, which is generally a good thing since it stops
+dnl  unexpected expansions and possible resultant errors.
+dnl
+dnl  But note that when a quoted string is being read, a # isn't special, so
+dnl  apostrophes in comments in quoted strings must be avoided or they'll be
+dnl  interpreted as a closing quote mark.  But when the quoted text is
+dnl  re-read # will still act like a normal comment, suppressing macro
+dnl  expansion.
+dnl
+dnl  For example,
+dnl
+dnl          # apostrophes in comments that're outside quotes are ok
+dnl          # and using macro names like PROLOGUE is ok too
+dnl          ...
+dnl          ifdef(`PIC',`
+dnl                  # but apostrophes aren't ok inside quotes
+dnl                  #                     ^--wrong
+dnl                  ...
+dnl                  # though macro names like PROLOGUE are still ok
+dnl                  ...
+dnl          ')
+dnl
+dnl  If macro expansion in a comment is wanted, use `#' in the .asm (ie. a
+dnl  quoted hash symbol), which will turn into # in the .s but get
+dnl  expansions done on that line.  This can make the .s more readable to
+dnl  humans, but it won't make a blind bit of difference to the assembler.
+dnl
+dnl  All the above applies, mutatis mutandis, when changecom() is used to
+dnl  select @ ! ; or whatever other commenting.
+dnl
+dnl
+dnl  Variations in m4 affecting gmp:
+dnl
+dnl  $# - When a macro is called as "foo" with no brackets, BSD m4 sets $#
+dnl       to 1, whereas GNU or SysV m4 set it to 0.  In all cases though
+dnl       "foo()" sets $# to 1.  This is worked around in various places.
+dnl
+dnl  len() - When "len()" is given an empty argument, BSD m4 evaluates to
+dnl       nothing, whereas GNU, SysV, and the new OpenBSD, evaluate to 0.
+dnl       See m4_length() below which works around this.
+dnl
+dnl  translit() - GNU m4 accepts character ranges like A-Z, and the new
+dnl       OpenBSD m4 does under option -g, but basic BSD and SysV don't.
+dnl
+dnl  popdef() - in BSD and SysV m4 popdef() takes multiple arguments and
+dnl       pops each, but GNU m4 only takes one argument.
+dnl
+dnl  push back - BSD m4 has some limits on the amount of text that can be
+dnl       pushed back.  The limit is reasonably big and so long as macros
+dnl       don't gratuitously duplicate big arguments it isn't a problem.
+dnl       Normally an error message is given, but sometimes it just hangs.
+dnl
+dnl  eval() &,|,^ - GNU and SysV m4 have bitwise operators &,|,^ available,
+dnl       but BSD m4 doesn't (contrary to what the man page suggests) and
+dnl       instead ^ is exponentiation.
+dnl
+dnl  eval() ?: - The C ternary operator "?:" is available in BSD m4, but not
+dnl       in SysV or GNU m4 (as of GNU m4 1.4 and betas of 1.5).
+dnl
+dnl  eval() -2^31 - BSD m4 has a bug where an eval() resulting in -2^31
+dnl       (ie. -2147483648) gives "-(".  Using -2147483648 within an
+dnl       expression is ok, it just can't be a final result.  "-(" will of
+dnl       course upset parsing, with all sorts of strange effects.
+dnl
+dnl  eval() <<,>> - SysV m4 doesn't support shift operators in eval() (on
+dnl       Solaris 7 /usr/xpg4/m4 has them but /usr/ccs/m4 doesn't).  See
+dnl       m4_lshift() and m4_rshift() below for workarounds.
+dnl
+dnl  ifdef() - OSF 4.0 m4 considers a macro defined to a zero value `0' or
+dnl       `00' etc as not defined.  See m4_ifdef below for a workaround.
+dnl
+dnl  m4wrap() sequence - in BSD m4, m4wrap() replaces any previous m4wrap()
+dnl       string, in SysV m4 it appends to it, and in GNU m4 it prepends.
+dnl       See m4wrap_prepend() below which brings uniformity to this.
+dnl
+dnl  m4wrap() 0xFF - old versions of BSD m4 store EOF in a C "char" under an
+dnl       m4wrap() and on systems where char is unsigned by default a
+dnl       spurious 0xFF is output.  This has been observed on recent Cray
+dnl       Unicos Alpha, Apple MacOS X, and HPUX 11 systems.  An autoconf
+dnl       test is used to check for this, see the m4wrap handling below.  It
+dnl       might work to end the m4wrap string with a dnl to consume the
+dnl       0xFF, but that probably induces the offending m4's to read from an
+dnl       already closed "FILE *", which could be bad on a glibc style
+dnl       stdio.
+dnl
+dnl  __file__,__line__ - GNU m4 and OpenBSD 2.7 m4 provide these, and
+dnl       they're used here to make error messages more informative.  GNU m4
+dnl       gives an unhelpful "NONE 0" in an m4wrap(), but that's worked
+dnl       around.
+dnl
+dnl  __file__ quoting - OpenBSD m4, unlike GNU m4, doesn't quote the
+dnl       filename in __file__, so care should be taken that no macro has
+dnl       the same name as a file, or an unwanted expansion will occur when
+dnl       printing an error or warning.
+dnl
+dnl  changecom() - BSD m4 changecom doesn't quite work like the man page
+dnl       suggests, in particular "changecom" or "changecom()" doesn't
+dnl       disable the comment feature, and multi-character comment sequences
+dnl       don't seem to work.  If the default `#' and newline aren't
+dnl       suitable it's necessary to change it to something else,
+dnl       eg. changecom(;).
+dnl
+dnl  OpenBSD 2.6 m4 - in this m4, eval() rejects decimal constants containing

+dnl
+dnl  SunOS /usr/bin/m4 - this m4 lacks a number of desired features,
+dnl       including $# and $@, defn(), m4exit(), m4wrap(), pushdef(),
+dnl       popdef().  /usr/5bin/m4 is a SysV style m4 which should always be
+dnl       available, and "configure" will reject /usr/bin/m4 in favour of
+dnl       /usr/5bin/m4 (if necessary).
+dnl
+dnl       The sparc code actually has modest m4 requirements currently and
+dnl       could manage with /usr/bin/m4, but there's no reason to put our
+dnl       macros through contortions when /usr/5bin/m4 is available or GNU

+dnl
+dnl  Put this unquoted on a line on its own at the start of a macro

+dnl
+dnl  The -1 for no parentheses at all means a macro that's meant to be used

+dnl
+dnl  Note that in BSD m4 there's no way to differentiate calls "foo" and
+dnl  "foo()", so in BSD m4 the distinction between the two isn't enforced.
+dnl  (In GNU and SysV m4 it can be checked, and is.)
+
+
+dnl  m4_assert_numargs is able to check its own arguments by calling
+dnl  assert_numargs_internal directly.
+dnl
+dnl  m4_doublequote($`'0) expands to ``$0'', whereas ``$`'0'' would expand

+dnl
+dnl  $`#' leaves $# in the new macro being defined, and stops # being

+dnl  Usage: deflit(name,value)
+dnl
+dnl  Like define(), but "name" expands like a literal, rather than taking

+dnl
+dnl  Limitations:
+dnl
+dnl  $ characters in the value part must have quotes to stop them looking
+dnl  like macro parameters.  For example, deflit(reg,`123+$`'4+567').  See
+dnl  defreg() below for handling simple register definitions like $7 etc.
+dnl
+dnl  "name()" is turned into "name", unfortunately.  In GNU and SysV m4 an
+dnl  error is generated when this happens, but in BSD m4 it will happen
+dnl  silently.  The problem is that in BSD m4 $# is 1 in both "name" or
+dnl  "name()", so there's no way to differentiate them.  Because we want
+dnl  plain "name" to turn into plain "value", we end up with "name()"
+dnl  turning into plain "value" too.
+dnl
+dnl  "name(foo)" will lose any whitespace after commas in "foo", for example
+dnl  "disp(%eax, %ecx)" would become "128(%eax,%ecx)".
+dnl
+dnl  These parentheses oddities shouldn't matter in assembler text, but if
+dnl  they do the suggested workaround is to write "name ()" or "name (foo)"
+dnl  to stop the parentheses looking like a macro argument list.  If a space
+dnl  isn't acceptable in the output, then write "name`'()" or "name`'(foo)".
+dnl  The `' is stripped when read, but again stops the parentheses looking
+dnl  like parameters.
+

+dnl  Usage: defreg(name,reg)
+dnl
+dnl  Give a name to a $ style register.  For example,
+dnl
+dnl         defreg(foo,$12)
+dnl
+dnl  defreg() inserts an extra pair of quotes after the $ so that it's not
+dnl  interpreted as an m4 macro parameter, ie. foo is actually $`'12.  m4
+dnl  strips those quotes when foo is expanded.
+dnl
+dnl  deflit() is used to make the new definition, so it will expand
+dnl  literally even if followed by parentheses ie. foo(99) will become
+dnl  $12(99).  (But there's nowhere that would be used is there?)
+dnl
+dnl  When making further definitions from existing defreg() macros, remember
+dnl  to use defreg() again to protect the $ in the new definitions too.  For

+dnl  definition is made, leaving a literal $4 that must be re-quoted.  On
+dnl  the other hand in something like the following ra is only expanded when
+dnl  ret is used and its $`'31 protection will have its desired effect at
+dnl  that time.
+dnl
+dnl         defreg(ra,$31)
+dnl         ...
+dnl         define(ret,`j ra')

+
+
+dnl  Usage: m4_instruction_wrapper()
+dnl
+dnl  Put this, unquoted, on a line on its own, at the start of a macro
+dnl  that's a wrapper around an assembler instruction.  It adds code to give
+dnl  a descriptive error message if the macro is invoked without arguments.
+dnl
+dnl  For example, suppose jmp needs to be wrapped,
+dnl
+dnl         define(jmp,

+dnl                 nop')
+dnl
+dnl  The point of m4_instruction_wrapper is to get a better error message
+dnl  than m4_assert_numargs would give if jmp is accidentally used as plain
+dnl  "jmp foo" instead of the intended "jmp( foo)".  "jmp()" with no
+dnl  argument also provokes the error message.
+dnl
+dnl  m4_instruction_wrapper should only be used with wrapped instructions

+
+dnl  Usage: UNROLL_LOG2, UNROLL_MASK, UNROLL_BYTES
+dnl         CHUNK_LOG2, CHUNK_MASK, CHUNK_BYTES
+dnl
+dnl  When code supports a variable amount of loop unrolling, the convention
+dnl  is to define UNROLL_COUNT to the number of limbs processed per loop.
+dnl  When testing code this can be varied to see how much the loop overhead
+dnl  is costing.  For example,
+dnl
+dnl         deflit(UNROLL_COUNT, 32)
+dnl
+dnl  If the forloop() generating the unrolled loop has a pattern processing
+dnl  more than one limb, the convention is to express this with CHUNK_COUNT.
+dnl  For example,
+dnl
+dnl         deflit(CHUNK_COUNT, 2)
+dnl
+dnl  The LOG2, MASK and BYTES definitions below are derived from these COUNT
+dnl  definitions.  If COUNT is redefined, the LOG2, MASK and BYTES follow
+dnl  the new definition automatically.
+dnl
+dnl  LOG2 is the log base 2 of COUNT.  MASK is COUNT-1, which can be used as
+dnl  a bit mask.  BYTES is GMP_LIMB_BYTES*COUNT, the number of bytes
+dnl  processed in each unrolled loop.
+dnl
+dnl  GMP_LIMB_BYTES is defined in a CPU specific m4 include file.  It
+dnl  exists only so the BYTES definitions here can be common to all CPUs.
+dnl  In the actual code for a given CPU, an explicit 4 or 8 may as well be
+dnl  used because the code is only for a particular CPU, it doesn't need to
+dnl  be general.
+dnl
+dnl  Note that none of these macros do anything except give conventional
+dnl  names to commonly used things.  You still have to write your own
+dnl  expressions for a forloop() and the resulting address displacements.
+dnl  Something like the following would be typical for 4 bytes per limb.
+dnl
+dnl         forloop(`i',0,UNROLL_COUNT-1,`
+dnl                 deflit(`disp',eval(i*4))
+dnl                 ...

+dnl  Defines for C global arrays and variables, with names matching what's
+dnl  used in the C code.
+dnl
+dnl  Notice that GSYM_PREFIX is included, unlike with the function defines
+dnl  above.  Also, "deflit" is used so that something like __clz_tab(%ebx)
+dnl  comes out as __gmpn_clz_tab(%ebx), for the benefit of CPUs with that
+dnl  style assembler syntax.

+
+
+dnl  Usage: ASM_START()
+dnl
+dnl  Emit any directives needed once at the start of an assembler file, like
+dnl  ".set noreorder" or whatever.  The default for this is nothing, but
+dnl  it's redefined by CPU specific m4 files.
+
+define(ASM_START)
+
+
+dnl  Usage: ASM_END()
+dnl
+dnl  Emit any directives needed once at the end of an assembler file.  The

+
+define(ASM_END)
+
+
+dnl  Usage: PROLOGUE(foo[,param])
+dnl         EPILOGUE(foo)
+dnl
+dnl  Emit directives to start or end a function.  GSYM_PREFIX is added by
+dnl  these macros if necessary, so the given "foo" is what the function will
+dnl  be called in C.
+dnl
+dnl  The second parameter to PROLOGUE is used only for some CPUs and should
+dnl  be omitted if not required.
+dnl
+dnl  Nested or overlapping PROLOGUE/EPILOGUE pairs are allowed, if that
+dnl  makes sense for the system.  The name given to EPILOGUE must be a
+dnl  currently open PROLOGUE.
+dnl
+dnl  If only one PROLOGUE is open then the name can be omitted from
+dnl  EPILOGUE.  This is encouraged, since it means the name only has to
+dnl  appear in one place, not two.
+dnl
+dnl  The given name "foo" is not fully quoted here, it will be macro
+dnl  expanded more than once.  This is the way the m4_list macros work, and
+dnl  it also helps the tune/many.pl program do a renaming like
+dnl  -D__gmpn_add_n=mpn_add_n_foo when GSYM_PREFIX is not empty.

+dnl
+dnl  The extra `' after LABEL_SUFFIX avoids any chance of a following

+dnl
+dnl  Emit a ".align" directive.  The alignment is specified in bytes, and
+dnl  will normally need to be a power of 2.  The actual ".align" generated
+dnl  is either bytes or logarithmic according to what ./configure finds the
+dnl  assembler needs.
+dnl

+dnl

+The code in this directory works for Cray vector systems such as C90,
+J90, T90 (both the CFP variant and the IEEE variant) and SV1.  (For
+the T3E and T3D systems, see the `alpha' subdirectory at the same
+level as the directory containing this file.)
+
+The cfp subdirectory is for systems utilizing the traditional Cray
+floating-point format, and the ieee subdirectory is for the newer
+systems that use the IEEE floating-point format.
+
+There are several issues that reduces speed on Cray systems.  For
+systems with cfp floating point, the main obstacle is the forming of
+128-bit products.  For IEEE systems, adding, and in particular
+computing carry is the main issue.  There are no vectorizing
+unsigned-less-than instructions, and the sequence that implement that
+operation is very long.
+
+Shifting is the only operation that is simple to make fast.  All Cray
+systems have a bitblt instructions (Vi Vj,Vj<Ak and Vi Vj,Vj>Ak) that
+should be really useful.
+
+For best speed for cfp systems, we need a mul_basecase, since that
+reduces the need for carry propagation to a minimum.  Depending on the
+size (vn) of the smaller of the two operands (V), we should split U and V
+in different chunk sizes:
+
+U split in 2 32-bit parts
+V split according to the table:
+parts			4	5	6	7	8
+bits/part		16	13	11	10	8
+max allowed vn		1	8	32	64	256
+number of multiplies	8	10	12	14	16
+peak cycles/limb	4	5	6	7	8
+
+U split in 3 22-bit parts
+V split according to the table:
+parts			3	4	5
+bits/part		22	16	13
+max allowed vn		16	1024	8192
+number of multiplies	9	12	15
+peak cycles/limb	4.5	6	7.5
+
+U split in 4 16-bit parts
+V split according to the table:
+parts			4
+bits/part		16
+max allowed vn		65536
+number of multiplies	16
+peak cycles/limb	8
+
+(A T90 CPU can accumulate two products per cycle.)
+
+IDEA:
+* Rewrite mpn_add_n:
+    short cy[n + 1];
+    #pragma _CRI ivdep
+      for (i = 0; i < n; i++)
+	{ s = up[i] + vp[i];
+	  rp[i] = s;
+	  cy[i + 1] = s < up[i]; }
+      more_carries = 0;
+    #pragma _CRI ivdep
+      for (i = 1; i < n; i++)
+	{ s = rp[i] + cy[i];
+	  rp[i] = s;
+	  more_carries += s < cy[i]; }
+      cys = 0;
+      if (more_carries)
+	{
+	  cys = rp[1] < cy[1];
+	  for (i = 2; i < n; i++)
+	    { rp[i] += cys;
+	      cys = rp[i] < cys; }
+	}
+      return cys + cy[n];
+
+* Write mpn_add3_n for adding three operands.  First add operands 1
+  and 2, and generate cy[].  Then add operand 3 to the partial result,
+  and accumulate carry into cy[].  Finally propagate carry just like
+  in the new mpn_add_n.
+
+IDEA:
+
+Store fewer bits, perhaps 62, per limb.  That brings mpn_add_n time
+down to 2.5 cycles/limb and mpn_addmul_1 times to 4 cycles/limb.  By
+storing even fewer bits per limb, perhaps 56, it would be possible to
+write a mul_mul_basecase that would run at effectively 1 cycle/limb.
+(Use VM here to better handle the romb-shaped multiply area, perhaps
+rounding operand sizes up to the next power of 2.)

+/* Compute Q = N/D with truncation.
+     N = {np,nn}
+     D = {dp,dn}
+     Q = {qp,nn-dn+1}
+     T = {scratch,nn+1} is scratch space
+   N and D are both untouched by the computation.
+   N and T may overlap; pass the same space if N is irrelevant after the call,
+   but note that tp needs an extra limb.
+
+   Operand requirements:
+     N >= D > 0
+     dp[dn-1] != 0
+     No overlap between the N, D, and Q areas.
+
+   This division function does not clobber its input operands, since it is
+   intended to support average-O(qn) division, and for that to be effective, it
+   cannot put requirements on callers to copy a O(nn) operand.
+
+   If a caller does not care about the value of {np,nn+1} after calling this
+   function, it should pass np also for the scratch argument.  This function
+   will then save some time and space by avoiding allocation and copying.
+   (FIXME: Is this a good design?  We only really save any copying for
+   already-normalised divisors, which should be rare.  It also prevents us from
+   reasonably asking for all scratch space we need.)
+
+   We write nn-dn+1 limbs for the quotient, but return void.  Why not return
+   the most significant quotient limb?  Look at the 4 main code blocks below
+   (consisting of an outer if-else where each arm contains an if-else). It is
+   tricky for the first code block, since the mpn_*_div_q calls will typically
+   generate all nn-dn+1 and return 0 or 1.  I don't see how to fix that unless
+   we generate the most significant quotient limb here, before calling
+   mpn_*_div_q, or put the quotient in a temporary area.  Since this is a
+   critical division case (the SB sub-case in particular) copying is not a good
+   idea.
+
+   It might make sense to split the if-else parts of the (qn + FUDGE
+   >= dn) blocks into separate functions, since we could promise quite
+   different things to callers in these two cases.  The 'then' case
+   benefits from np=scratch, and it could perhaps even tolerate qp=np,
+   saving some headache for many callers.
+
+   FIXME: Scratch allocation leaves a lot to be desired.  E.g., for the MU size
+   operands, we do not reuse the huge scratch for adjustments.  This can be a
+   serious waste of memory for the largest operands.

+/* Divide a={src,size} by d=divisor and store the quotient in q={dst,size}.
+   q will only be correct if d divides a exactly.
+
+   A separate loop is used for shift==0 because n<<GMP_LIMB_BITS doesn't
+   give zero on all CPUs (for instance it doesn't on the x86s).  This
+   separate loop might run faster too, helping odd divisors.
+
+   Possibilities:
+
+   mpn_divexact_1c could be created, accepting and returning c.  This would
+   let a long calculation be done piece by piece.  Currently there's no
+   particular need for that, and not returning c means that a final umul can
+   be skipped.
+
+   Another use for returning c would be letting the caller know whether the
+   division was in fact exact.  It would work just to return the carry bit
+   "c=(l>s)" and let the caller do a final umul if interested.
+
+   When the divisor is even, the factors of two could be handled with a
+   separate mpn_rshift, instead of shifting on the fly.  That might be
+   faster on some CPUs and would mean just the shift==0 style loop would be
+   needed.
+
+   If n<<GMP_LIMB_BITS gives zero on a particular CPU then the separate
+   shift==0 loop is unnecessary, and could be eliminated if there's no great
+   speed difference.
+
+   It's not clear whether "/" is the best way to handle size==1.  Alpha gcc
+   2.95 for instance has a poor "/" and might prefer the modular method.
+   Perhaps a tuned parameter should control this.
+
+   If src[size-1] < divisor then dst[size-1] will be zero, and one divide
+   step could be skipped.  A test at last step for s<divisor (or ls in the
+   even case) might be a good way to do that.  But if this code is often
+   used with small divisors then it might not be worth bothering  */

+
+   thereby allowing src[i]*inverse to be scheduled back as far as desired,

+   handing on the dependent chain.
+
+   The carry handling consists of determining the c for the next iteration.
+   This is the same as described above, namely look for any borrow from
+   src[i]-c, and at the high of 3*q.
+
+   high(3*q) is done with two comparisons as above (in c2 and c3).  The
+   borrow from src[i]-c is incorporated into those by noting that if there's
+   a carry then then we have src[i]-c == 0xFF..FF or 0xFF..FE, in turn

+
+   The net effect is that with good pipelining this loop should be able to

+
+   If multiply-by-inverse is never viable, then NORM and UNNORM thresholds
+   will be MP_SIZE_T_MAX and only the plain division code is included.
+
+   Otherwise mul-by-inverse is better than plain division above some
+   threshold, and best results are obtained by having code for both present.
+
+   The main reason for separating the norm and unnorm cases is that not all
+   CPUs give zero for "n0 >> GMP_LIMB_BITS" which would arise in the unnorm
+   code used on an already normalized divisor.
+
+   If UDIV_NEEDS_NORMALIZATION is false then plain division uses the same
+   non-shifting code for both the norm and unnorm cases, though with
+   different criteria for skipping a division, and with different thresholds
+   of course.  And in fact if inversion is never viable, then that simple
+   non-shifting division would be all that's left.
+
+   The NORM and UNNORM thresholds might not differ much, but if there's
+   going to be separate code for norm and unnorm then it makes sense to have
+   separate thresholds.  One thing that's possible is that the
+   mul-by-inverse might be better only for normalized divisors, due to that
+   case not needing variable bit shifts.
+
+   Notice that the thresholds are tested after the decision to possibly skip
+   one divide step, so they're based on the actual number of divisions done.
+
+   For the unnorm case, it would be possible to call mpn_lshift to adjust
+   the dividend all in one go (into the quotient space say), rather than
+   limb-by-limb in the loop.  This might help if mpn_lshift is a lot faster
+   than what the compiler can generate for EXTRACT.  But this is left to CPU
+   specific implementations to consider, especially since EXTRACT isn't on
+   the dependent chain.  */

+/* Return the value {ptr,size}*2^exp, and negative if sign<0.  Must have
+   size>=1, and a non-zero high limb ptr[size-1].
+
+   When we know the fp format, the result is truncated towards zero.  This is
+   consistent with other gmp conversions, like mpz_set_f or mpz_set_q, and is
+   easy to implement and test.
+
+   When we do not know the format, such truncation seems much harder.  One
+   would need to defeat any rounding mode, including round-up.
+
+   It's felt that GMP is not primarily concerned with hardware floats, and
+   really isn't enhanced by getting involved with hardware rounding modes
+   (which could even be some weird unknown style), so something unambiguous and
+   straightforward is best.
+
+
+   The IEEE code below is the usual case, it knows either a 32-bit or 64-bit
+   limb and is done with shifts and masks.  The 64-bit case in particular
+   should come out nice and compact.
+
+   The generic code used to work one bit at a time, which was not only slow,
+   but implicitly relied upon denorms for intermediates, since the lowest bits'
+   weight of a perfectly valid fp number underflows in non-denorm.  Therefore,
+   the generic code now works limb-per-limb, initially creating a number x such
+   that 1 <= x <= BASE.  (BASE is reached only as result of rounding.)  Then
+   x's exponent is scaled with explicit code (not ldexp to avoid libm
+   dependency).  It is a tap-dance to avoid underflow or overflow, beware!
+
+
+   Traps:
+
+   Hardware traps for overflow to infinity, underflow to zero, or unsupported
+   denorms may or may not be taken.  The IEEE code works bitwise and so
+   probably won't trigger them, the generic code works by float operations and
+   so probably will.  This difference might be thought less than ideal, but
+   again its felt straightforward code is better than trying to get intimate
+   with hardware exceptions (of perhaps unknown nature).
+
+
+   Not done:
+
+   mpz_get_d in the past handled size==1 with a cast limb->double.  This might
+   still be worthwhile there (for up to the mantissa many bits), but for
+   mpn_get_d here, the cost of applying "exp" to the resulting exponent would
+   probably use up any benefit a cast may have over bit twiddling.  Also, if
+   the exponent is pushed into denorm range then bit twiddling is the only
+   option, to ensure the desired truncation is obtained.
+
+
+   Other:
+
+   For reference, note that HPPA 8000, 8200, 8500 and 8600 trap FCNV,UDW,DBL
+   to the kernel for values >= 2^63.  This makes it slow, and worse the kernel
+   Linux (what versions?) apparently uses untested code in its trap handling
+   routines, and gets the sign wrong.  We don't use such a limb-to-double
+   cast, neither in the IEEE or generic code.  */

+/* Conversion of U {up,un} to a string in base b.  Internally, we convert to
+   base B = b^m, the largest power of b that fits a limb.  Basic algorithms:
+
+  A) Divide U repeatedly by B, generating a quotient and remainder, until the
+     quotient becomes zero.  The remainders hold the converted digits.  Digits
+     come out from right to left.  (Used in mpn_bc_get_str.)
+
+  B) Divide U by b^g, for g such that 1/b <= U/b^g < 1, generating a fraction.
+     Then develop digits by multiplying the fraction repeatedly by b.  Digits
+     come out from left to right.  (Currently not used herein, except for in
+     code for converting single limbs to individual digits.)
+
+  C) Compute B^1, B^2, B^4, ..., B^s, for s such that B^s is just above
+     sqrt(U).  Then divide U by B^s, generating quotient and remainder.
+     Recursively convert the quotient, then the remainder, using the
+     precomputed powers.  Digits come out from left to right.  (Used in
+     mpn_dc_get_str.)
+
+  When using algorithm C, algorithm B might be suitable for basecase code,
+  since the required b^g power will be readily accessible.
+
+  Optimization ideas:
+  1. The recursive function of (C) could use less temporary memory.  The powtab
+     allocation could be trimmed with some computation, and the tmp area could
+     be reduced, or perhaps eliminated if up is reused for both quotient and
+     remainder (it is currently used just for remainder).
+  2. Store the powers of (C) in normalized form, with the normalization count.
+     Quotients will usually need to be left-shifted before each divide, and
+     remainders will either need to be left-shifted of right-shifted.
+  3. In the code for developing digits from a single limb, we could avoid using
+     a full umul_ppmm except for the first (or first few) digits, provided base
+     is even.  Subsequent digits can be developed using plain multiplication.
+     (This saves on register-starved machines (read x86) and on all machines
+     that generate the upper product half using a separate instruction (alpha,
+     powerpc, IA-64) or lacks such support altogether (sparc64, hppa64).
+  4. Separate mpn_dc_get_str basecase code from code for small conversions. The
+     former code will have the exact right power readily available in the
+     powtab parameter for dividing the current number into a fraction.  Convert
+     that using algorithm B.
+  5. Completely avoid division.  Compute the inverses of the powers now in
+     powtab instead of the actual powers.
+  6. Decrease powtab allocation for even bases.  E.g. for base 10 we could save
+     about 30% (1-log(5)/log(10)).
+
+  Basic structure of (C):
+    mpn_get_str:
+      if POW2_P (n)
+	...
+      else
+	if (un < GET_STR_PRECOMPUTE_THRESHOLD)
+	  mpn_bx_get_str (str, base, up, un);
+	else
+	  precompute_power_tables
+	  mpn_dc_get_str
+
+    mpn_dc_get_str:
+	mpn_tdiv_qr
+	if (qn < GET_STR_DC_THRESHOLD)
+	  mpn_bc_get_str
+	else
+	  mpn_dc_get_str
+	if (rn < GET_STR_DC_THRESHOLD)
+	  mpn_bc_get_str
+	else
+	  mpn_dc_get_str
+
+
+  The reason for the two threshold values is the cost of
+  precompute_power_tables.  GET_STR_PRECOMPUTE_THRESHOLD will be
+  considerably larger than GET_STR_DC_THRESHOLD.  */
+
+
+/* The x86s and m68020 have a quotient and remainder "div" instruction and

+   in version 0.4 of the book.
+
+   Some adaptations were introduced, to allow product mod B^m-1 and return the
+   value e.
+
+   We introduced a correction in such a way that "the value of
+   B^{n+h}-T computed at step 8 cannot exceed B^n-1" (the book reads
+   "2B^n-1").
+
+   Maximum scratch needed by this branch <= 2*n, but have to fit 3*rn
+   in the scratch, i.e. 3*rn <= 2*n: we require n>4.
+
+   We use a wrapped product modulo B^m-1.  NOTE: is there any normalisation
+   problem for the [0] class?  It shouldn't: we compute 2*|A*X_h - B^{n+h}| <
+   B^m-1.  We may get [0] if and only if we get AX_h = B^{n+h}.  This can
+   happen only if A=B^{n}/2, but this implies X_h = B^{h}*2-1 i.e., AX_h =
+   B^{n+h} - A, then we get into the "negative" branch, where X_h is not
+   incremented (because A < B^n).
+
+   FIXME: the scratch for mulmod_bnm1 does not currently fit in the scratch, it
+   is allocated apart.

+ *   (r1 | r0) = s(r1, r0) (r0 | r1) = s(r1, r0) (r2, r1)
+ *
+ * where s(x,y) = (-1)^{(x-1)(y-1)/4} = (-1)^[x = y = 3 (mod 4)].
+ *
+ * If r1 is even, r2 must be odd. We have
+ *
+ *   (r1 | r0) = (r1 - r0 | r0) = (-1)^(r0-1)/2 (r0 - r1 | r0)
+ *             = (-1)^(r0-1)/2 s(r0, r0 - r1) (r0 | r0 - r1)
+ *             = (-1)^(r0-1)/2 s(r0, r0 - r1) (r1 | r0 - r1)
+ *
+ * Now, if r1 = 0 (mod 4), then the sign factor is +1, and repeating
+ * q1 times gives
+ *
+ *   (r1 | r0) = (r1 | r2) = (r3 | r2)
+ *
+ * On the other hand, if r1 = 2 (mod 4), the sign factor is
+ * (-1)^{(r0-1)/2}, and repeating q1 times gives the exponent
+ *
+ *   (r0-1)/2 + (r0-r1-1)/2 + ... + (r0 - (q1-1) r1)/2
+ *   = q1 (r0-1)/2 + q1 (q1-1)/2
+ *
+ * and we can summarize the even case as
+ *
+ *   (r1 | r0) = t(r1, r0, q1) (r3 | r2)
+ *
+ * where t(x,y,q) = (-1)^{[x = 2 (mod 4)] (q(y-1)/2 + y(q-1)/2)}
+ *
+ * What about termination? The remainder sequence ends with (0|1) = 1
+ * (or (0 | r) = 0 if r != 1). What are the possible cases? If r1 is
+ * odd, r2 may be zero. If r1 is even, then r2 = r0 - q1 r1 is odd and
+ * hence non-zero. We may have r3 = r1 - q2 r2 = 0.
+ *
+ * Examples: (11|15) = - (15|11) = - (4|11)
+ *            (4|11) =    (4| 3) =   (1| 3)

+/* Calculate a remainder from {p,n} divided by 2^(GMP_NUMB_BITS*3/4)-1.
+   The remainder is not fully reduced, it's any limb value congruent to
+   {p,n} modulo that divisor.
+
+   This implementation is only correct when GMP_NUMB_BITS is a multiple of
+   4.
+
+   FIXME: If GMP_NAIL_BITS is some silly big value during development then
+   it's possible the carry accumulators c0,c1,c2 could overflow.
+
+   General notes:
+
+   The basic idea is to use a set of N accumulators (N=3 in this case) to
+   effectively get a remainder mod 2^(GMP_NUMB_BITS*N)-1 followed at the end
+   by a reduction to GMP_NUMB_BITS*N/M bits (M=4 in this case) for a
+   remainder mod 2^(GMP_NUMB_BITS*N/M)-1.  N and M are chosen to give a good
+   set of small prime factors in 2^(GMP_NUMB_BITS*N/M)-1.
+
+   N=3 M=4 suits GMP_NUMB_BITS==32 and GMP_NUMB_BITS==64 quite well, giving
+   a few more primes than a single accumulator N=1 does, and for no extra
+   cost (assuming the processor has a decent number of registers).
+
+   For strange nailified values of GMP_NUMB_BITS the idea would be to look
+   for what N and M give good primes.  With GMP_NUMB_BITS not a power of 2
+   the choices for M may be opened up a bit.  But such things are probably
+   best done in separate code, not grafted on here.  */

+/* Calculate an r satisfying
+
+           r*B^k + a - c == q*d
+
+   where B=2^GMP_LIMB_BITS, a is {src,size}, k is either size or size-1
+   (the caller won't know which), and q is the quotient (discarded).  d must
+   be odd, c can be any limb value.
+
+   If c<d then r will be in the range 0<=r<d, or if c>=d then 0<=r<=d.
+
+   This slightly strange function suits the initial Nx1 reduction for GCDs
+   or Jacobi symbols since the factors of 2 in B^k can be ignored, leaving
+   -r == a mod d (by passing c=0).  For a GCD the factor of -1 on r can be
+   ignored, or for the Jacobi symbol it can be accounted for.  The function
+   also suits divisibility and congruence testing since if r=0 (or r=d) is
+   obtained then a==c mod d.
+
+
+   r is a bit like the remainder returned by mpn_divexact_by3c, and is the
+   sort of remainder mpn_divexact_1 might return.  Like mpn_divexact_by3c, r
+   represents a borrow, since effectively quotient limbs are chosen so that
+   subtracting that multiple of d from src at each step will produce a zero
+   limb.
+
+   A long calculation can be done piece by piece from low to high by passing
+   the return value from one part as the carry parameter to the next part.
+   The effective final k becomes anything between size and size-n, if n
+   pieces are used.
+
+
+   A similar sort of routine could be constructed based on adding multiples
+   of d at each limb, much like redc in mpz_powm does.  Subtracting however
+   has a small advantage that when subtracting to cancel out l there's never
+   a borrow into h, whereas using an addition would put a carry into h
+   depending whether l==0 or l!=0.
+
+
+   In terms of efficiency, this function is similar to a mul-by-inverse
+   mpn_mod_1.  Both are essentially two multiplies and are best suited to
+   CPUs with low latency multipliers (in comparison to a divide instruction
+   at least.)  But modexact has a few less supplementary operations, only
+   needs low part and high part multiplies, and has fewer working quantities
+   (helping CPUs with few registers).
+
+
+   In the main loop it will be noted that the new carry (call it r) is the
+   sum of the high product h and any borrow from l=s-c.  If c<d then we will
+   have r<d too, for the following reasons.  Let q=l*inverse be the quotient
+   limb, so that q*d = B*h + l, where B=2^GMP_NUMB_BITS.  Now if h=d-1 then
+
+       l = q*d - B*(d-1) <= (B-1)*d - B*(d-1) = B-d
+
+   But if l=s-c produces a borrow when c<d, then l>=B-d+1 and hence will
+   never have h=d-1 and so r=h+borrow <= d-1.
+
+   When c>=d, on the other hand, h=d-1 can certainly occur together with a
+   borrow, thereby giving only r<=d, as per the function definition above.
+
+   As a design decision it's left to the caller to check for r=d if it might
+   be passing c>=d.  Several applications have c<d initially so the extra
+   test is often unnecessary, for example the GCDs or a plain divisibility
+   d|a test will pass c=0.
+
+
+   The special case for size==1 is so that it can be assumed c<=d in the
+   high<=divisor test at the end.  c<=d is only guaranteed after at least
+   one iteration of the main loop.  There's also a decent chance one % is
+   faster than a binvert_limb, though that will depend on the processor.
+
+   A CPU specific implementation might want to omit the size==1 code or the
+   high<divisor test.  mpn/x86/k6/mode1o.asm for instance finds neither
+   useful.  */

+     Unfortunately, since mpn_mu_divappr_q does not return the partial

+     solve that.

+   The idea of the algorithm used herein is to compute a smaller inverted value

+   for developing quotient bits.  This algorithm was presented at ICMS 2006.

+
+  * The itch/scratch scheme isn't perhaps such a good idea as it once seemed,
+    demonstrated by the fact that the mpn_invertappr function's scratch needs
+    mean that we need to keep a large allocation long after it is needed.
+    Things are worse as mpn_mul_fft does not accept any scratch parameter,
+    which means we'll have a large memory hole while in mpn_mul_fft.  In

+  Compute the least significant half of the product {xy,n}*{yp,n}, or
+  formally {rp,n} = {xy,n}*{yp,n} Mod (B^n).
+
+  Above the given threshold, the Divide and Conquer strategy is used.
+  The operands are split in two, and a full product plus two mullo
+  are used to obtain the final result. The more natural strategy is to
+  split in two halves, but this is far from optimal when a
+  sub-quadratic multiplication is used.
+
+  Mulders suggests an unbalanced split in favour of the full product,
+  split n = n1 + n2, where an = n1 <= n2 = (1-a)n; i.e. 0 < a <= 1/2.
+
+  To compute the value of a, we assume that the cost of mullo for a
+  given size ML(n) is a fraction of the cost of a full product with
+  same size M(n), and the cost M(n)=n^e for some exponent 1 < e <= 2;
+  then we can write:
+
+  ML(n) = 2*ML(an) + M((1-a)n) => k*M(n) = 2*k*M(n)*a^e + M(n)*(1-a)^e
+
+  Given a value for e, want to minimise the value of k, i.e. the
+  function k=(1-a)^e/(1-2*a^e).
+
+  With e=2, the exponent for schoolbook multiplication, the minimum is
+  given by the values a=1-a=1/2.
+
+  With e=log(3)/log(2), the exponent for Karatsuba (aka toom22),
+  Mulders compute (1-a) = 0.694... and we approximate a with 11/36.
+
+  Other possible approximations follow:
+  e=log(5)/log(3) [Toom-3] -> a ~= 9/40
+  e=log(7)/log(4) [Toom-4] -> a ~= 7/39
+  e=log(11)/log(6) [Toom-6] -> a ~= 1/8
+  e=log(15)/log(8) [Toom-8] -> a ~= 1/10
+
+  The values above where obtained with the following trivial commands
+  in the gp-pari shell:
+
+fun(e,a)=(1-a)^e/(1-2*a^e)
+mul(a,b,c)={local(m,x,p);if(b-c<1/10000,(b+c)/2,m=1;x=b;forstep(p=c,b,(b-c)/8,if(fun(a,p)<m,m=fun(a,p);x=p));mul(a,(b+x)/2,(c+x)/2))}
+contfracpnqn(contfrac(mul(log(2*2-1)/log(2),1/2,0),5))
+contfracpnqn(contfrac(mul(log(3*2-1)/log(3),1/2,0),5))
+contfracpnqn(contfrac(mul(log(4*2-1)/log(4),1/2,0),5))
+contfracpnqn(contfrac(mul(log(6*2-1)/log(6),1/2,0),3))

+
+  For an actual implementation, the assumption that M(n)=n^e is
+  incorrect, as a consequence also the assumption that ML(n)=k*M(n)
+  with a constant k is wrong.
+
+  But theory suggest us two things:
+  - the best the multiplication product is (lower e), the more k
+    approaches 1, and a approaches 0.
+
+  - A value for a smaller than optimal is probably less bad than a
+    bigger one: e.g. let e=log(3)/log(2), a=0.3058_ the optimal
+    value, and k(a)=0.808_ the mul/mullo speed ratio. We get
+    k(a+1/6)=0.929_ but k(a-1/6)=0.865_.

+/* PERFSQR_MOD_* detects non-squares using residue tests.
+
+   A macro PERFSQR_MOD_TEST is setup by gen-psqr.c in perfsqr.h.  It takes
+   {up,usize} modulo a selected modulus to get a remainder r.  For 32-bit or
+   64-bit limbs this modulus will be 2^24-1 or 2^48-1 using PERFSQR_MOD_34,
+   or for other limb or nail sizes a PERFSQR_PP is chosen and PERFSQR_MOD_PP
+   used.  PERFSQR_PP_NORM and PERFSQR_PP_INVERTED are pre-calculated in this
+   case too.
+
+   PERFSQR_MOD_TEST then makes various calls to PERFSQR_MOD_1 or
+   PERFSQR_MOD_2 with divisors d which are factors of the modulus, and table
+   data indicating residues and non-residues modulo those divisors.  The
+   table data is in 1 or 2 limbs worth of bits respectively, per the size of
+   each d.
+
+   A "modexact" style remainder is taken to reduce r modulo d.
+   PERFSQR_MOD_IDX implements this, producing an index "idx" for use with
+   the table data.  Notice there's just one multiplication by a constant
+   "inv", for each d.
+
+   The modexact doesn't produce a true r%d remainder, instead idx satisfies
+   "-(idx<<PERFSQR_MOD_BITS) == r mod d".  Because d is odd, this factor
+   -2^PERFSQR_MOD_BITS is a one-to-one mapping between r and idx, and is
+   accounted for by having the table data suitably permuted.
+
+   The remainder r fits within PERFSQR_MOD_BITS which is less than a limb.
+   In fact the GMP_LIMB_BITS - PERFSQR_MOD_BITS spare bits are enough to fit
+   each divisor d meaning the modexact multiply can take place entirely
+   within one limb, giving the compiler the chance to optimize it, in a way
+   that say umul_ppmm would not give.
+
+   There's no need for the divisors d to be prime, in fact gen-psqr.c makes
+   a deliberate effort to combine factors so as to reduce the number of
+   separate tests done on r.  But such combining is limited to d <=
+   2*GMP_LIMB_BITS so that the table data fits in at most 2 limbs.
+
+   Alternatives:
+
+   It'd be possible to use bigger divisors d, and more than 2 limbs of table
+   data, but this doesn't look like it would be of much help to the prime
+   factors in the usual moduli 2^24-1 or 2^48-1.
+
+   The moduli 2^24-1 or 2^48-1 are nothing particularly special, they're
+   just easy to calculate (see mpn_mod_34lsub1) and have a nice set of prime
+   factors.  2^32-1 and 2^64-1 would be equally easy to calculate, but have
+   fewer prime factors.
+
+   The nails case usually ends up using mpn_mod_1, which is a lot slower
+   than mpn_mod_34lsub1.  Perhaps other such special moduli could be found
+   for the nails case.  Two-term things like 2^30-2^15-1 might be
+   candidates.  Or at worst some on-the-fly de-nailing would allow the plain
+   2^24-1 to be used.  Currently nails are too preliminary to be worried
+   about.

+  BASIC ALGORITHM, Compute U^E mod M, where M < B^n is odd.
+
+  1. W <- U
+
+  2. T <- (B^n * U) mod M                Convert to REDC form
+
+  3. Compute table U^1, U^3, U^5... of E-dependent size
+
+  4. While there are more bits in E
+       W <- power left-to-right base-k
+
+
+  TODO:
+
+   * Make getbits a macro, thereby allowing it to update the index operand.
+     That will simplify the code using getbits.  (Perhaps make getbits' sibling
+     getbit then have similar form, for symmetry.)
+
+   * Write an itch function.  Or perhaps get rid of tp parameter since the huge
+     pp area is allocated locally anyway?
+
+   * Choose window size without looping.  (Superoptimize or think(tm).)
+
+   * Handle small bases with initial, reduction-free exponentiation.
+
+   * Call new division functions, not mpn_tdiv_qr.
+
+   * Consider special code for one-limb M.
+
+   * How should we handle the redc1/redc2/redc_n choice?
+     - redc1:  T(binvert_1limb)  + e * (n)   * (T(mullo-1x1) + n*T(addmul_1))
+     - redc2:  T(binvert_2limbs) + e * (n/2) * (T(mullo-2x2) + n*T(addmul_2))
+     - redc_n: T(binvert_nlimbs) + e * (T(mullo-nxn) + T(M(n)))
+     This disregards the addmul_N constant term, but we could think of
+     that as part of the respective mullo.
+
+   * When U (the base) is small, we should start the exponentiation with plain
+     operations, then convert that partial result to REDC form.
+
+   * When U is just one limb, should it be handled without the k-ary tricks?
+     We could keep a factor of B^n in W, but use U' = BU as base.  After
+     multiplying by this (pseudo two-limb) number, we need to multiply by 1/B
+     mod M.

+
+   The main reason for a separate shift==0 case is that not all CPUs give
+   zero for "n0 >> GMP_LIMB_BITS" which would arise in the general case
+   code used on shift==0.  shift==0 is also reasonably common in mp_bases
+   big_base, for instance base==10 on a 64-bit limb.
+
+   Under shift!=0 it would be possible to call mpn_lshift to adjust the
+   dividend all in one go (into the quotient space say), rather than
+   limb-by-limb in the loop.  This might help if mpn_lshift is a lot faster
+   than what the compiler can generate for EXTRACT.  But this is left to CPU
+   specific implementations to consider, especially since EXTRACT isn't on
+   the dependent chain.
+
+   If size==0 then the result is simply xsize limbs of zeros, but nothing
+   special is done for that, since it wouldn't be a usual call, and
+   certainly never arises from mpn_get_str which is our main caller.  */

+/* This side-channel silent division algorithm reduces the partial remainder by
+   GMP_NUMB_BITS/2 bits at a time, compared to GMP_NUMB_BITS for the main
+   division algorithm.  We actually do not insist on reducing by exactly
+   GMP_NUMB_BITS/2, but may leave a partial remainder that is D*B^i to 3D*B^i
+   too large (B is the limb base, D is the divisor, and i is the induction
+   variable); the subsequent step will handle the extra partial remainder bits.
+
+   With that partial remainder reduction, each step generates a quotient "half
+   limb".  The outer loop generates two quotient half limbs, an upper (q1h) and
+   a lower (q0h) which are stored sparsely in separate limb arrays.  These
+   arrays are added at the end; using separate arrays avoids data-dependent
+   carry propagation which could else pose a side-channel leakage problem.
+
+   The quotient half limbs may be between -3 to 0 from the accurate value
+   ("accurate" being the one which corresponds to a reduction to a principal
+   partial remainder).  Too small quotient half limbs correspond to too large
+   remainders, which we reduce later, as described above.
+
+   In order to keep quotients from getting too big, corresponding to a negative

+  Compute the least significant half of the product {xy,n}*{yp,n}, or
+  formally {rp,n} = {xy,n}*{yp,n} Mod (B^n).
+
+  Above the given threshold, the Divide and Conquer strategy is used.
+  The operand is split in two, and a full square plus a mullo
+  is used to obtain the final result. The more natural strategy is to
+  split in two halves, but this is far from optimal when a
+  sub-quadratic multiplication is used.
+
+  Mulders suggests an unbalanced split in favour of the full product,
+  split n = n1 + n2, where an = n1 <= n2 = (1-a)n; i.e. 0 < a <= 1/2.
+
+  To compute the value of a, we assume that the cost of mullo for a
+  given size ML(n) is a fraction of the cost of a full product with
+  same size M(n), and the cost M(n)=n^e for some exponent 1 < e <= 2;
+  then we can write:
+
+  ML(n) = 2*ML(an) + M((1-a)n) => k*M(n) = 2*k*M(n)*a^e + M(n)*(1-a)^e
+
+  Given a value for e, want to minimise the value of k, i.e. the
+  function k=(1-a)^e/(1-2*a^e).
+
+  With e=2, the exponent for schoolbook multiplication, the minimum is
+  given by the values a=1-a=1/2.
+
+  With e=log(3)/log(2), the exponent for Karatsuba (aka toom22),
+  Mulders compute (1-a) = 0.694... and we approximate a with 11/36.
+
+  Other possible approximations follow:
+  e=log(5)/log(3) [Toom-3] -> a ~= 9/40
+  e=log(7)/log(4) [Toom-4] -> a ~= 7/39
+  e=log(11)/log(6) [Toom-6] -> a ~= 1/8
+  e=log(15)/log(8) [Toom-8] -> a ~= 1/10
+
+  The values above where obtained with the following trivial commands
+  in the gp-pari shell:
+
+fun(e,a)=(1-a)^e/(1-2*a^e)
+mul(a,b,c)={local(m,x,p);if(b-c<1/10000,(b+c)/2,m=1;x=b;forstep(p=c,b,(b-c)/8,if(fun(a,p)<m,m=fun(a,p);x=p));mul(a,(b+x)/2,(c+x)/2))}
+contfracpnqn(contfrac(mul(log(2*2-1)/log(2),1/2,0),5))
+contfracpnqn(contfrac(mul(log(3*2-1)/log(3),1/2,0),5))
+contfracpnqn(contfrac(mul(log(4*2-1)/log(4),1/2,0),5))
+contfracpnqn(contfrac(mul(log(6*2-1)/log(6),1/2,0),3))
+contfracpnqn(contfrac(mul(log(8*2-1)/log(8),1/2,0),3))

+
+  For an actual implementation, the assumption that M(n)=n^e is
+  incorrect, as a consequence also the assumption that ML(n)=k*M(n)
+  with a constant k is wrong.
+
+  But theory suggest us two things:
+  - the best the multiplication product is (lower e), the more k
+    approaches 1, and a approaches 0.
+
+  - A value for a smaller than optimal is probably less bad than a
+    bigger one: e.g. let e=log(3)/log(2), a=0.3058_ the optimal
+    value, and k(a)=0.808_ the mul/mullo speed ratio. We get
+    k(a+1/6)=0.929_ but k(a-1/6)=0.865_.

+		  division.  (This step is implemented by an mpn_divrem call.)
+
+	       2) Is the most significant limb from the remainder < p, where p
+		  is the product of the most significant limb from the quotient
+		  and the next(d)?  (Next(d) denotes the next ignored limb from
+		  the denominator.)  If it is, decrement qest, and adjust the
+		  remainder accordingly.
+

+		  quotient.  The algorithm terminates.

+		  borrow out, decrement qest, and adjust the remainder

+   This function finds the first (smallest) factor represented in

+   reached some sensible limit, such as the square root of the input number.
+
+   The caller can limit the factoring effort by passing NPRIMES.  The function
+   will then divide until that limit, or perhaps a few primes more.  A position
+   which only mpn_trialdiv can make sense of is returned in the WHERE
+   parameter.  It can be used for restarting the factoring effort; the first

+
+   Input:        1. A non-negative number T = {tp,tn}

+
+
+This directory contains mpn functions for the IA-64 architecture.
+
+
+CODE ORGANIZATION
+
+	mpn/ia64          itanium-2, and generic ia64
+
+The code here has been optimized primarily for Itanium 2.  Very few Itanium 1
+chips were ever sold, and Itanium 2 is more powerful, so the latter is what
+we concentrate on.
+
+
+
+CHIP NOTES
+
+The IA-64 ISA keeps instructions three and three in 128 bit bundles.
+Programmers/compilers need to put explicit breaks `;;' when there are WAW or
+RAW dependencies, with some notable exceptions.  Such "breaks" are typically
+at the end of a bundle, but can be put between operations within some bundle
+types too.
+
+The Itanium 1 and Itanium 2 implementations can under ideal conditions
+execute two bundles per cycle.  The Itanium 1 allows 4 of these instructions
+to do integer operations, while the Itanium 2 allows all 6 to be integer
+operations.
+
+Taken cloop branches seem to insert a bubble into the pipeline most of the
+time on Itanium 1.
+
+Loads to the fp registers bypass the L1 cache and thus get extremely long
+latencies, 9 cycles on the Itanium 1 and 6 cycles on the Itanium 2.
+
+The software pipeline stuff using br.ctop instruction causes delays, since
+many issue slots are taken up by instructions with zero predicates, and
+since many extra instructions are needed to set things up.  These features
+are clearly designed for code density, not speed.
+
+Misc pipeline limitations (Itanium 1):
+* The getf.sig instruction can only execute in M0.
+* At most four integer instructions/cycle.
+* Nops take up resources like any plain instructions.
+
+Misc pipeline limitations (Itanium 2):
+* The getf.sig instruction can only execute in M0.
+* Nops take up resources like any plain instructions.
+
+
+ASSEMBLY SYNTAX
+
+.align pads with nops in a text segment, but gas 2.14 and earlier
+incorrectly byte-swaps its nop bundle in big endian mode (eg. hpux), making
+it come out as break instructions.  We use the ALIGN() macro in
+mpn/ia64/ia64-defs.m4 when it might be executed across.  That macro
+suppresses any .align if the problem is detected by configure.  Lack of
+alignment might hurt performance but will at least be correct.
+
+foo:: to create a global symbol is not accepted by gas.  Use separate
+".global foo" and "foo:" instead.
+
+.global is the standard global directive.  gas accepts .globl, but hpux "as"
+doesn't.
+
+.proc / .endp generates the appropriate .type and .size information for ELF,
+so the latter directives don't need to be given explicitly.
+
+.pred.rel "mutex"... is standard for annotating predicate register
+relationships.  gas also accepts .pred.rel.mutex, but hpux "as" doesn't.
+
+.pred directives can't be put on a line with a label, like
+".Lfoo: .pred ...", the HP assembler on HP-UX 11.23 rejects that.
+gas is happy with it, and past versions of HP had seemed ok.
+
+// is the standard comment sequence, but we prefer "C" since it inhibits m4
+macro expansion.  See comments in ia64-defs.m4.
+
+
+REGISTER USAGE
+
+Special:
+   r0: constant 0
+   r1: global pointer (gp)
+   r8: return value
+   r12: stack pointer (sp)
+   r13: thread pointer (tp)

+
+
+================================================================
+mpn_add_n, mpn_sub_n:
+
+The current code runs at 1.25 c/l on Itanium 2.
+
+================================================================
+mpn_mul_1:
+
+The current code runs at 2 c/l on Itanium 2.
+
+Using a blocked approach, working off of 4 separate places in the operands,
+one could make use of the xma accumulation, and approach 1 c/l.
+
+	ldf8 [up]
+	xma.l
+	xma.hu
+	stf8  [wrp]
+
+================================================================
+mpn_addmul_1:
+
+The current code runs at 2 c/l on Itanium 2.
+
+It seems possible to use a blocked approach, as with mpn_mul_1.  We should
+read rp[] to integer registers, allowing for just one getf.sig per cycle.
+
+	ld8  [rp]
+	ldf8 [up]
+	xma.l
+	xma.hu
+	getf.sig
+	add+add+cmp+cmp
+	st8  [wrp]
+
+These 10 instructions can be scheduled to approach 1.667 cycles, and with
+the 4 cycle latency of xma, this means we need at least 3 blocks.  Using
+ldfp8 we could approach 1.583 c/l.
+
+================================================================
+mpn_submul_1:
+
+The current code runs at 2.25 c/l on Itanium 2.  Getting to 2 c/l requires
+ldfp8 with all alignment headache that implies.
+
+================================================================
+mpn_addmul_N
+
+For best speed, we need to give up using mpn_addmul_2 as the main multiply
+building block, and instead take multiple v limbs per loop.  For the Itanium
+1, we need to take about 8 limbs at a time for full speed.  For the Itanium
+2, something like mpn_addmul_4 should be enough.
+
+The add+cmp+cmp+add we use on the other codes is optimal for shortening
+recurrencies (1 cycle) but the sequence takes up 4 execution slots.  When
+recurrency depth is not critical, a more standard 3-cycle add+cmp+add is
+better.

+
+================================================================
+mpn_lshift, mpn_rshift
+
+The current code runs at 1 cycle/limb on Itanium 2.
+
+Using 63 separate loops, we could use the double-word shrp instruction.
+That instruction has a plain single-cycle latency.  We need 63 loops since
+this instruction only accept immediate count.  That would lead to a somewhat
+silly code size, but the speed would be 0.75 c/l on Itanium 2 (by using shrp
+each cycle plus shl/shr going down I1 for a further limb every second
+cycle).
+
+================================================================
+mpn_copyi, mpn_copyd
+
+The current code runs at 0.5 c/l on Itanium 2.  But that is just for L1
+cache hit.  The 4-way unrolled loop takes just 2 cycles, and thus load-use
+scheduling isn't great.  It might be best to actually use modulo scheduled
+loops, since that will allow us to do better load-use scheduling without too
+much unrolling.
+
+Depending on size or operand alignment, we get 1 c/l or 0.5 c/l on Itanium
+2, according to tune/speed.  Cache bank conflicts?

+C TODO
+C  * Further optimize feed-in and wind-down code, both for speed and code size.
+C  * Handle low limb input and results specially, using a common stf8 in the
+C    epilogue.
+C  * Use 1 c/l carry propagation scheme in wind-down code.
+C  * Use extra pointer registers for `up' and rp to speed up feed-in loads.
+C  * Work out final differences with mul_1.asm.  That function is 300 bytes
+C    smaller than this due to better loop scheduling and thus simpler feed-in
+C    code.

+C TODO
+C  * Clean up variable names, and try to decrease the number of distinct
+C    registers used.
+C  * Clean up feed-in code to not require zeroing several registers.
+C  * Make sure we don't depend on uninitialised predicate registers.
+C  * Could perhaps save a few cycles by using 1 c/l carry propagation in
+C    wind-down code.
+C  * Ultimately rewrite.  The problem with this code is that it first uses a
+C    loaded u value in one xma pair, then leaves it live over several unrelated
+C    xma pairs, before it uses it again.  It should actually be quite possible
+C    to just swap some aligned xma pairs around.  But we should then schedule
+C    u loads further from the first use.

+C TODO
+C  * Consider using special code for small n, using something like
+C    "switch (8 * (n >= 8) + (n mod 8))" to enter it and feed-in code.
+C  * The non-nc code was trimmed cycle for cycle to its current state.  It is
+C    probably hard to save more that an odd cycle there.  The nc code is much
+C    cruder (since tune/speed doesn't have any applicable direct measurements).
+C  * Without the nc entry points, this becomes around 1800 bytes of object
+C    code; the nc code adds over 1000 bytes.  We should perhaps sacrifice a
+C    few cycles for the non-nc code and let it fall into the nc code.

+C This code is a bit messy, and not as similar to mode1o.asm as desired.
+
+C The critical path during initialization is for computing the inverse of the
+C divisor.  Since odd divisors are probably common, we conditionally execute
+C the initial count_trailing_zeros code and the downshift.
+
+C Possible improvement: Merge more of the feed-in code into the inverse
+C computation.

+C This was generated by gcc, then the loops were optimized.  The preinv entry
+C point was shoehorned into the file.  Lots of things outside the loops could
+C be streamlined.  It would probably be a good idea to merge the loops for
+C normalized and unnormalized divisor, since the shifting stuff is done for
+C free in parallel with other operations.  It would even be possible to merge
+C all loops, if the ld8 were made conditional.

+dnl  since we're not expecting to execute across a PROLOGUE(), at least not
+dnl  currently.

+dnl  Usage: ALIGN(bytes)
+dnl
+dnl  Emit a ".align" directive.  "bytes" is eval()ed, so can be an
+dnl  expression.
+dnl
+dnl  This version overrides the definition in mpn/asm-defs.m4.  We suppress
+dnl  any .align if the gas byte-swapped-nops bug was detected by configure
+dnl  GMP_ASM_IA64_ALIGN_OK.

+
+
+dnl  Usage: ASSERT([pr] [,code])
+dnl
+dnl  Require that the given predicate register is true after executing the
+dnl  test code.  For example,
+dnl
+dnl         ASSERT(p6,
+dnl         `       cmp.eq  p6,p0 = r3, r4')
+dnl
+dnl  If the predicate register argument is empty then nothing is tested, the
+dnl  code is just executed.  This can be used for setups required by later
+dnl  ASSERTs.  The code argument can be omitted to just test a predicate
+dnl  with no special setup code.
+dnl
+dnl  For convenience, stops are inserted before and after the code emitted.

+C Itanium 2:    1
+
+C This code is scheduled deeply since the plain shift instructions shr and shl
+C have a latency of 4 (on Itanium) or 3 (on Itanium 2).  Poor scheduling of
+C these instructions cause a 10 cycle replay trap on Itanium.
+
+C The ld8 scheduling should probably be decreased to make the function smaller.
+C Good lfetch  will make sure we never stall anyway.
+
+C We should actually issue the first ld8 at cycle 0, and the first BSH/FSH pair
+C at cycle 2.  Judicious use of predicates could allow us to issue more ld8's
+C in the prologue.

+C close to 3 insn/limb, for nearly 0.5 c/l.
+
+C Computing n/3 needs 16 cycles, which is a lot of startup overhead.
+C We therefore use a plain while-style loop:
+C	add		n = -3, n
+C	cmp.le		p9, p0 = 3, n

+C Alternatively, we could table n/3 for, say, n < 256, and predicate the

+C The summing-up code at the end was written quickly, and could surely be

+C mp_limb_t mpn_modexact_1c_odd (mp_srcptr src, mp_size_t size,
+C                                mp_limb_t divisor, mp_limb_t carry);
+C
+C The modexact algorithm is usually conceived as a dependent chain
+C
+C	l = src[i] - c
+C	q = low(l * inverse)
+C	c = high(q*divisor) + (src[i]<c)
+C
+C but we can work the src[i]-c into an xma by calculating si=src[i]*inverse
+C separately (off the dependent chain) and using
+C
+C	q = low(c * inverse + si)
+C	c = high(q*divisor + c)
+C
+C This means the dependent chain is simply xma.l followed by xma.hu, for a
+C total 8 cycles/limb on itanium-2.
+C
+C The reason xma.hu works for the new c is that the low of q*divisor is
+C src[i]-c (being the whole purpose of the q generated, and it can be
+C verified algebraically).  If there was an underflow from src[i]-c, then
+C there will be an overflow from (src-c)+c, thereby adding 1 to the new c
+C the same as the borrow bit (src[i]<c) gives in the first style shown.
+C
+C Incidentally, fcmp is not an option for treating src[i]-c, since it
+C apparently traps to the kernel for unnormalized operands like those used
+C and generated by ldf8 and xma.  On one GNU/Linux system it took about 1200
+C cycles.
+C
+C
+C First Limb:
+C
+C The first limb uses q = (src[0]-c) * inverse shown in the first style.
+C This lets us get the first q as soon as the inverse is ready, without
+C going through si=s*inverse.  Basically at the start we have c and can use
+C it while waiting for the inverse, whereas for the second and subsequent
+C limbs it's the other way around, ie. we have the inverse and are waiting
+C for c.
+C
+C At .Lentry the first two instructions in the loop have been done already.
+C The load of f11=src[1] at the start (predicated on size>=2), and the
+C calculation of q by the initial different scheme.
+C
+C
+C Entry Sequence:
+C
+C In the entry sequence, the critical path is the calculation of the
+C inverse, so this is begun first and optimized.  Apart from that, ar.lc is
+C established nice and early so the br.cloop's should predict perfectly.
+C And the load for the low limbs src[0] and src[1] can be initiated long
+C ahead of where they're needed.
+C
+C
+C Inverse Calculation:
+C
+C The initial 8-bit inverse is calculated using a table lookup.  If it hits
+C L1 (which is likely if we're called several times) then it should take a
+C total 4 cycles, otherwise hopefully L2 for 9 cycles.  This is considered
+C the best approach, on balance.  It could be done bitwise, but that would
+C probably be about 14 cycles (2 per bit beyond the first couple).  Or it
+C could be taken from 4 bits to 8 with xmpy doubling as used beyond 8 bits,
+C but that would be about 11 cycles.
+C
+C The table is not the same as binvert_limb_table, instead it's 256 bytes,
+C designed to be indexed by the low byte of the divisor.  The divisor is
+C always odd, so the relevant data is every second byte in the table.  The
+C padding lets us use zxt1 instead of extr.u, the latter would cost an extra
+C cycle because it must go down I0, and we're using the first I0 slot to get
+C ip.  The extra 128 bytes of padding should be insignificant compared to
+C typical ia64 code bloat.
+C
+C Having the table in .text allows us to use IP-relative addressing,
+C avoiding a fetch from ltoff.  .rodata is apparently not suitable for use
+C IP-relative, it gets a linker relocation overflow on GNU/Linux.
+C
+C
+C Load Scheduling:
+C
+C In the main loop, the data loads are scheduled for an L2 hit, which means
+C 6 cycles for the data ready to use.  In fact we end up 7 cycles ahead.  In
+C any case that scheduling is achieved simply by doing the load (and xmpy.l
+C for "si") in the immediately preceding iteration.
+C
+C The main loop requires size >= 2, and we handle size==1 by an initial
+C br.cloop to enter the loop only if size>1.  Since ar.lc is established
+C early, this should predict perfectly.
+C
+C
+C Not done:
+C
+C Consideration was given to using a plain "(src[0]-c) % divisor" for
+C size==1, but cycle counting suggests about 50 for the sort of approach
+C taken by gcc __umodsi3, versus about 47 for the modexact.  (Both assuming
+C L1 hits for their respective fetching.)
+C
+C Consideration was given to a test for high<divisor and replacing the last
+C loop iteration with instead c-=src[size-1] followed by c+=d if underflow.
+C Branching on high<divisor wouldn't be good since a mispredict would cost
+C more than the loop iteration saved, and the condition is of course data
+C dependent.  So the theory would be to shorten the loop count if
+C high<divisor, and predicate extra operations at the end.  That would mean
+C a gain of 6 when high<divisor, or a cost of 2 if not.
+C
+C Whether such a tradeoff is a win on average depends on assumptions about
+C how many bits in the high and the divisor.  If both are uniformly
+C distributed then high<divisor about 50% of the time.  But smallish
+C divisors (less chance of high<divisor) might be more likely from
+C applications (mpz_divisible_ui, mpz_gcd_ui, etc).  Though biggish divisors
+C would be normal internally from say mpn/generic/perfsqr.c.  On balance,
+C for the moment, it's felt the gain is not really enough to be worth the
+C trouble.
+C
+C
+C Enhancement:
+C
+C Process two source limbs per iteration using a two-limb inverse and a
+C sequence like
+C
+C	ql  = low (c * il + sil)	quotient low limb
+C	qlc = high(c * il + sil)
+C	qh1 = low (c * ih + sih)	quotient high, partial
+C
+C	cl = high (ql * d + c)		carry out of low
+C	qh = low (qlc * 1 + qh1)	quotient high limb
+C
+C	new c = high (qh * d + cl)	carry out of high
+C
+C This would be 13 cycles/iteration, giving 6.5 cycles/limb.  The two limb
+C s*inverse as sih:sil = sh:sl * ih:il would be calculated off the dependent
+C chain with 4 multiplies.  The bigger inverse would take extra time to
+C calculate, but a one limb iteration to handle an odd size could be done as
+C soon as 64-bits of inverse were ready.
+C
+C Perhaps this could even extend to a 3 limb inverse, which might promise 17
+C or 18 cycles for 3 limbs, giving 5.66 or 6.0 cycles/limb.

+C TODO
+C  * Clean up variable names, and try to decrease the number of distinct
+C    registers used.
+C  * Clean up feed-in code to not require zeroing several registers.
+C  * Make sure we don't depend on uninitialized predicate registers.
+C  * Could perhaps save a few cycles by using 1 c/l carry propagation in
+C    wind-down code.
+C  * Ultimately rewrite.  The problem with this code is that it first uses a
+C    loaded u value in one xma pair, then leaves it live over several unrelated
+C    xma pairs, before it uses it again.  It should actually be quite possible
+C    to just swap some aligned xma pairs around.  But we should then schedule
+C    u loads further from the first use.

+;;; Commentary:
+;;
+;; gmpasm-mode is a major mode for editing m4 processed assembler code and
+;; m4 macro files in GMP.  It's similar to m4-mode, but has a number of
+;; settings better suited to GMP.
+;;
+;;
+;; Install
+;; -------
+;;
+;; To make M-x gmpasm-mode available, put gmpasm-mode.el somewhere in your
+;; load-path and the following in your .emacs
+;;
+;;	(autoload 'gmpasm-mode "gmpasm-mode" nil t)
+;;
+;; To use gmpasm-mode automatically on all .asm and .m4 files, put the
+;; following in your .emacs
+;;
+;;	(add-to-list 'auto-mode-alist '("\\.asm\\'" . gmpasm-mode))
+;;	(add-to-list 'auto-mode-alist '("\\.m4\\'" . gmpasm-mode))
+;;
+;; To have gmpasm-mode only on gmp files, try instead something like the
+;; following, which uses it only in a directory starting with "gmp", or a
+;; sub-directory of such.
+;;
+;;	(add-to-list 'auto-mode-alist
+;;	             '("/gmp.*/.*\\.\\(asm\\|m4\\)\\'" . gmpasm-mode))
+;;
+;; Byte compiling will slightly speed up loading.  If you want a docstring
+;; in the autoload you can use M-x update-file-autoloads if you set it up
+;; right.
+;;
+;;
+;; Emacsen
+;; -------
+;;
+;; GNU Emacs 20.x, 21.x and XEmacs 20.x all work well.  GNU Emacs 19.x
+;; should work if replacements for the various 20.x-isms are available,
+;; though comment-region with "C" doesn't do the right thing.

+
+                      M68K MPN SUBROUTINES
+
+
+This directory contains mpn functions for various m68k family chips.
+
+
+CODE ORGANIZATION
+
+	m68k             m68000, m68010, m68060
+	m68k/mc68020     m68020, m68030, m68040, and CPU32
+
+
+The m5200 "coldfire", which is m68000 less a few instructions, currently has
+no assembler code support.
+
+
+STATUS
+
+The code herein is old and poorly maintained.  If somebody really cared, it
+could be optimized substantially.  For example,
+
+* mpn_add_n and mpn_sub_n could, with more unrolling be improved from 6 to
+  close to 4 c/l (on m68040).
+
+* The multiplication loops could be sped up by using the FPU.
+
+* mpn_lshift by 31 should use the special-case mpn_rshift by 1 code, and
+  vice versa mpn_rshift by 31 use the special lshift by 1, when operand
+  overlap permits.
+
+* On 68000, mpn_mul_1, mpn_addmul_1 and mpn_submul_1 could check for a
+  16-bit multiplier and use two multiplies per limb, not four.
+
+  Similarly various other _1 operations like mpn_mod_1, mpn_divrem_1,
+  mpn_divexact_1, mpn_modexact_1c_odd.
+
+* On 68000, mpn_lshift and mpn_rshift could use a roll and mask instead of
+  lsrl and lsll.  This promises to be a speedup, effectively trading a 6+2*n
+  shift for one or two 4 cycle masks.  Suggested by Jean-Charles Meyrignac.
+
+* config.guess detects 68000, 68010, CPU32 and 68020 by running some code,
+  but relies on system information for 030, 040 and 060.  Can they be
+  identified by running some code?  Currently this only makes a difference
+  to the compiler options selected, since we have no specific asm code for
+  those chips.
+
+One novel idea for 68000 would be to use a 16-bit limb instead of 32-bits.
+This would suit the native 16x16 multiply, but might make it difficult to
+get full value from the native 32x32 add/sub/etc.  This would be an ABI
+option, and would select "__GMP_SHORT_LIMB" in gmp.h.
+
+Naturally an entirely new set of asm subroutines would be needed for a
+16-bit limb.  Also there's various places in the C code assuming limb>=long,
+which would need to be updated, eg. mpz_set_ui.  Some of the nails changes
+may have helped cover some of this.
+
+
+ASM FILES
+
+The .asm files are put through m4 for macro processing, and with the help of
+configure give either MIT or Motorola syntax.  The generic mpn/asm-defs.m4
+is used, together with mpn/m68k/m68k-defs.m4.  See comments in those files.
+
+Not all possible syntax variations are covered.  GCC config/m68k for
+instance has things like $ for immediates on CRDS or reversed cmp order for
+AT&T SGS.  These could probably be handled if anyone really needs it.
+
+
+CALLING CONVENTIONS
+
+The SVR4 standard has an int of 32 bits, and all parameters 32-bit aligned
+on the stack.
+
+PalmOS and perhaps various embedded systems intended for 68000 however use
+an int of 16 bits and parameters only 16-bit aligned on the stack.  This is
+generated by "gcc -mshort" (and is the default for the PalmOS gcc port, we
+believe).
+
+The asm files adapt to these two ABIs by checking sizeof(unsigned), coming
+through config.m4 as SIZEOF_UNSIGNED.  Only mpn_lshift and mpn_rshift are
+affected, all other routines take longs and pointers, which are 32-bits in
+both cases.
+
+Strictly speaking the size of an int doesn't determine the stack padding
+convention.  But if int is 16 bits then we can definitely say the host
+system is not SVR4, and therefore may as well assume we're in 16-bit stack
+alignment.

+
+STATUS
+
+The code herein is old and poorly maintained.
+
+* The .s files assume the system uses a "_" underscore prefix, which
+  should be controlled by configure.
+
+* The mc88110/*.S files are using the defunct "sysdep.h" configuration
+  scheme and won't compile.
+
+Conversion to the current m4 .asm style wouldn't be difficult.

+; Common overhead is about 11 cycles/invocation.
+
+; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention.)
+
+; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
+
+; To enhance speed:
+; 1. Unroll main loop 4-8 times.
+; 2. Schedule code to avoid WB contention.  It might be tempting to move the
+;    ld instruction in the loops down to save 2 cycles (less WB contention),
+;    but that looses because the ultimate value will be read from outside
+;    the allocated space.  But if we handle the ultimate multiplication in
+;    the tail, we can do this.
+; 3. Make the multiplication with less instructions.  I think the code for
+;    (S2_LIMB >= 0x10000) is not minimal.
+; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
+; less cycles/limb; the (S2_LIMB < 0x10000) case would run in 11
+; cycles/limb.  (Assuming infinite unrolling.)

+
+This directory contains mpn functions optimized for MIPS3.  Example of
+processors that implement MIPS3 are R4000, R4400, R4600, R4700, and R8000.
+
+RELEVANT OPTIMIZATION ISSUES
+
+1. On the R4000 and R4400, branches, both the plain and the "likely" ones,
+   take 3 cycles to execute.  (The fastest possible loop will take 4 cycles,
+   because of the delay insn.)
+
+   On the R4600, branches takes a single cycle
+
+   On the R8000, branches often take no noticeable cycles, as they are
+   executed in a separate function unit..
+
+2. The R4000 and R4400 have a load latency of 4 cycles.
+
+3. On the R4000 and R4400, multiplies take a data-dependent number of
+   cycles, contrary to the SGI documentation.  There seem to be 3 or 4
+   possible latencies.
+
+4. The R1x000 processors can issue one floating-point operation, two integer
+   operations, and one memory operation per cycle.  The FPU has very short
+   latencies, while the integer multiply unit is non-pipelined.  We should
+   therefore write fp based mpn_Xmul_1.
+
+STATUS
+
+Good...

+This directory contains mpn functions for various HP PA-RISC chips.  Code
+that runs faster on the PA7100 and later implementations, is in the pa7100
+directory.
+
+RELEVANT OPTIMIZATION ISSUES
+
+  Load and Store timing
+
+On the PA7000 no memory instructions can issue the two cycles after a store.
+For the PA7100, this is reduced to one cycle.
+
+The PA7100 has a lookup-free cache, so it helps to schedule loads and the
+dependent instruction really far from each other.
+
+STATUS
+
+1. mpn_mul_1 could be improved to 6.5 cycles/limb on the PA7100, using the
+   instructions below (but some sw pipelining is needed to avoid the
+   xmpyu-fstds delay):
+
+	fldds	s1_ptr
+
+	xmpyu
+	fstds	N(%r30)
+	xmpyu
+	fstds	N(%r30)
+
+	ldws	N(%r30)
+	ldws	N(%r30)
+	ldws	N(%r30)
+	ldws	N(%r30)
+
+	addc
+	stws	res_ptr
+	addc
+	stws	res_ptr
+
+	addib	Loop
+
+2. mpn_addmul_1 could be improved from the current 10 to 7.5 cycles/limb
+   (asymptotically) on the PA7100, using the instructions below.  With proper
+   sw pipelining and the unrolling level below, the speed becomes 8
+   cycles/limb.
+
+	fldds	s1_ptr
+	fldds	s1_ptr
+
+	xmpyu
+	fstds	N(%r30)
+	xmpyu

+
+	addib
+
+3. For the PA8000 we have to stick to using 32-bit limbs before compiler
+   support emerges.  But we want to use 64-bit operations whenever possible,
+   in particular for loads and stores.  It is possible to handle mpn_add_n
+   efficiently by rotating (when s1/s2 are aligned), masking+bit field
+   inserting when (they are not).  The speed should double compared to the
+   code used today.
+
+
+
+
+LABEL SYNTAX
+
+The HP-UX assembler takes labels starting in column 0 with no colon,
+
+	L$loop  ldws,mb -4(0,%r25),%r22
+
+Gas on hppa GNU/Linux however requires a colon,
+
+	L$loop: ldws,mb -4(0,%r25),%r22
+
+This is covered by using LDEF() from asm-defs.m4.  An alternative would be
+to use ".label" which is accepted by both,
+
+		.label  L$loop
+		ldws,mb -4(0,%r25),%r22
+
+but that's not as nice to look at, not if you're used to assembler code
+having labels in column 0.

+C This file has caused a lot of trouble, since it demands PIC reference to
+C static data, which triggers bugs in gas (at least version 2.7 through
+C 2.11.2).  When the bug is triggered, many bogus relocs are generated.  The
+C current solution is to stuff data right into the code, and refer it using

+
+PIPELINE SUMMARY
+
+The PA8x00 processors have an orthogonal 4-way out-of-order pipeline.  Each
+cycle two ALU operations and two MEM operations can issue, but just one of the
+MEM operations may be a store.  The two ALU operations can be almost any
+combination of non-memory operations.  Unlike every other processor, integer
+and fp operations are completely equal here; they both count as just ALU
+operations.
+
+Unfortunately, some operations cause hickups in the pipeline.  Combining
+carry-consuming operations like ADD,DC with operations that does not set carry
+like ADD,L cause long delays.  Skip operations also seem to cause hickups.  If
+several ADD,DC are issued consecutively, or if plain carry-generating ADD feed
+ADD,DC, stalling does not occur.  We can effectively issue two ADD,DC
+operations/cycle.
+
+Latency scheduling is not as important as making sure to have a mix of ALU and
+MEM operations, but for full pipeline utilization, it is still a good idea to
+do some amount of latency scheduling.
+
+Like for all other processors, RAW memory scheduling is critically important.
+Since integer multiplication takes place in the floating-point unit, the GMP
+code needs to handle this problem frequently.
+
+STATUS
+
+* mpn_lshift and mpn_rshift run at 1.5 cycles/limb on PA8000 and at 1.0
+  cycles/limb on PA8500.  With latency scheduling, the numbers could
+  probably be improved to 1.0 cycles/limb for all PA8x00 chips.
+
+* mpn_add_n and mpn_sub_n run at 2.0 cycles/limb on PA8000 and at about
+  1.6875 cycles/limb on PA8500.  With latency scheduling, this could
+  probably be improved to get close to 1.5 cycles/limb.  A problem is the
+  stalling of carry-inputting instructions after instructions that do not
+  write to carry.
+
+* mpn_mul_1, mpn_addmul_1, and mpn_submul_1 run at between 5.625 and 6.375
+  on PA8500 and later, and about a cycle/limb slower on older chips.  The
+  code uses ADD,DC for adjacent limbs, and relies heavily on reordering.

+C  The feed-in and wind-down code has not yet been scheduled.  Many cycles
+C  could be saved there per call.
+
+C  DESCRIPTION:
+C  The main loop "BIG" is 4-way unrolled, mainly to allow
+C  effective use of ADD,DC.  Delays in moving data via the cache from the FP
+C  registers to the IU registers, have demanded a deep software pipeline, and
+C  a lot of stack slots for partial products in flight.
+C
+C  CODE STRUCTURE:
+C  save-some-registers
+C  do 0, 1, 2, or 3 limbs
+C  if done, restore-some-regs and return
+C  save-many-regs
+C  do 4, 8, ... limb
+C  restore-all-regs
+
+C  STACK LAYOUT:
+C  HP-PA stack grows upwards.  We could allocate 8 fewer slots by using the
+C  slots marked FREE, as well as some slots in the caller's "frame marker".

+C 8500,8600,8700:	5.625
+
+C  The feed-in and wind-down code has not yet been scheduled.  Many cycles
+C  could be saved there per call.
+
+C  DESCRIPTION:
+C  The main loop "BIG" is 4-way unrolled, mainly to allow
+C  effective use of ADD,DC.  Delays in moving data via the cache from the FP
+C  registers to the IU registers, have demanded a deep software pipeline, and
+C  a lot of stack slots for partial products in flight.
+C
+C  CODE STRUCTURE:
+C  save-some-registers
+C  do 0, 1, 2, or 3 limbs
+C  if done, restore-some-regs and return
+C  save-many-regs
+C  do 4, 8, ... limb
+C  restore-all-regs
+
+C  STACK LAYOUT:
+C  HP-PA stack grows upwards.  We could allocate 8 fewer slots by using the
+C  slots marked FREE, as well as some slots in the caller's "frame marker".

+C 8000,8200:		7
+C 8500,8600,8700:	6.5
+
+C  The feed-in and wind-down code has not yet been scheduled.  Many cycles
+C  could be saved there per call.
+
+C  DESCRIPTION:
+C  The main loop "BIG" is 4-way unrolled, mainly to allow
+C  effective use of ADD,DC.  Delays in moving data via the cache from the FP
+C  registers to the IU registers, have demanded a deep software pipeline, and
+C  a lot of stack slots for partial products in flight.
+C
+C  CODE STRUCTURE:
+C  save-some-registers
+C  do 0, 1, 2, or 3 limbs
+C  if done, restore-some-regs and return
+C  save-many-regs
+C  do 4, 8, ... limb
+C  restore-all-regs
+
+C  STACK LAYOUT:
+C  HP-PA stack grows upwards.  We could allocate 8 fewer slots by using the
+C  slots marked FREE, as well as some slots in the caller's "frame marker".

+dnl  The POWER architecture has no unsigned 32x32->64 bit multiplication
+dnl  instruction.  To obtain that operation, we have to use the 32x32->64
+dnl  signed multiplication instruction, and add the appropriate compensation to
+dnl  the high limb of the result.  We add the multiplicand if the multiplier
+dnl  has its most significant bit set, and we add the multiplier if the
+dnl  multiplicand has its most significant bit set.  We need to preserve the
+dnl  carry flag between each iteration, so we have to compute the compensation
+dnl  carefully (the natural, srai+and doesn't work).  Since all POWER can
+dnl  branch in zero cycles, we use conditional branches for the compensation.

+dnl  The POWER architecture has no unsigned 32x32->64 bit multiplication
+dnl  instruction.  To obtain that operation, we have to use the 32x32->64
+dnl  signed multiplication instruction, and add the appropriate compensation to
+dnl  the high limb of the result.  We add the multiplicand if the multiplier
+dnl  has its most significant bit set, and we add the multiplier if the
+dnl  multiplicand has its most significant bit set.  We need to preserve the
+dnl  carry flag between each iteration, so we have to compute the compensation
+dnl  carefully (the natural, srai+and doesn't work).  Since all POWER can
+dnl  branch in zero cycles, we use conditional branches for the compensation.

+                    POWERPC 32-BIT MPN SUBROUTINES
+
+
+This directory contains mpn functions for various 32-bit PowerPC chips.
+
+
+CODE ORGANIZATION
+
+	directory	  used for
+	================================================
+	powerpc           generic, 604, 604e, 744x, 745x
+	powerpc/750       740, 750, 7400, 7410
+
+
+The top-level powerpc directory is currently mostly aimed at 604/604e but
+should be reasonable on all powerpcs.
+
+
+
+STATUS
+
+The code is quite well optimized for the 604e, other chips have had less
+attention.
+
+Altivec SIMD available in 74xx might hold some promise, but unfortunately
+GMP only guarantees 32-bit data alignment, so there's lots of fiddling
+around with partial operations at the start and end of limb vectors.  A
+128-bit limb would be a novel idea, but is unlikely to be practical, since
+it would have to work with ordinary +, -, * etc in the C code.
+
+Also, Altivec isn't very well suited for the GMP multiplication needs.
+Using floating-point based multiplication has much better better performance
+potential for all current powerpcs, both the ones with slow integer multiply
+units (603, 740, 750, 7400, 7410) and those with fast (604, 604e, 744x,
+745x).  This is because all powerpcs do some level of pipelining in the FPU:
+
+603 and 750 can sustain one fmadd every 2nd cycle.
+604 and 604e can sustain one fmadd per cycle.
+7400 and 7410 can sustain 3 fmadd in 4 cycles.
+744x and 745x can sustain 4 fmadd in 5 cycles.
+
+
+
+REGISTER NAMES
+
+The normal powerpc convention is to give registers as plain numbers, like
+"mtctr 6", but on Apple MacOS X (powerpc*-*-rhapsody* and
+powerpc*-*-darwin*) the assembler demands an "r" like "mtctr r6".  Note
+however when register 0 in an instruction means a literal zero the "r" is
+omitted, for instance "lwzx r6,0,r7".
+
+The GMP code uses the "r" forms, powerpc-defs.m4 transforms them to plain
+numbers according to what GMP_ASM_POWERPC_R_REGISTERS finds is needed.
+(Note that this style isn't fully general, as the identifier r4 and the
+register r4 will not be distinguishable on some systems.  However, this is
+not a problem for the limited GMP assembly usage.)

+C 12 mem insn
+C 8 serializing insn
+C 8 int multiply
+C 25 int reg write
+C 9 int ops (8 of which serialize)
+C
+C The multiply insns need 16 cycles/4limb.

+C branch.
+C
+C The mullw has the inverse in the first operand, since 0xAA..AB won't allow
+C any early-out.  The src[] data normally won't either, but there's at least
+C a chance, whereas 0xAA..AB never will.  If, for instance, src[] is all
+C zeros (not a sensible input of course) we run at 7.0 c/l on ppc750.
+C
+C The mulhwu has the "3" multiplier in the second operand, which lets 750 and

+C Alternatives:

+C Fetching half words would allow add instead for accumulating, instead of

+C
+C For PIC, the inverse is established arithmetically since it measures about
+C 5 cycles faster than the nonsense needed to access binvert_limb_table in
+C SVR4 or Darwin style PIC.  AIX might be better, since it avoids bl/mflr to
+C get at the GOT/TOC/whatever.
+C
+C Using divwu for size==1 measured about 10 cycles slower on 604e, or about
+C 3-5 cycles faster on 750.  For now it doesn't seem worth bothering with.
+C
+C The loop allows an early-out on mullw for the inverse, and on mulhwu for
+C the divisor.  So the fastest is for instance divisor==1 (inverse==-1), and
+C the slowest is anything giving a full 32-bits in both, such as
+C divisor==0xDEADBEEF (inverse==0x904B300F).  These establish the stated
+C range above for 750 and 7400.

+dnl  Called: PROLOGUE_cpu(GSYM_PREFIX`'foo)
+dnl
+dnl  This is the same as the default in mpn/asm-defs.m4, but with ALIGN(4)
+dnl  not 8.
+dnl
+dnl  4-byte alignment is normally enough, certainly it's what gcc gives.  We
+dnl  don't want bigger alignment within PROLOGUE since it can introduce
+dnl  padding into multiple-entrypoint routines, and with gas such padding is
+dnl  zero words, which are not valid instructions.

+	TYPE(`$1',`function')

+
+dnl  Usage: r0 ... r31, cr0 ... cr7
+dnl
+dnl  Registers names, either left as "r0" etc or mapped to plain 0 etc,
+dnl  according to the result of the GMP_ASM_POWERPC_REGISTERS configure
+dnl  test.

+forloop(i,0,31,`deflit(`f'i,i)')
+forloop(i,0,7, `deflit(`cr'i,i)')
+')
+
+
+dnl  Usage: ASSERT(cond,instructions)
+dnl
+dnl  If WANT_ASSERT is 1, output the given instructions and expect the given
+dnl  flags condition to then be satisfied.  For example,
+dnl
+dnl         ASSERT(eq, `cmpwi r6, 123')
+dnl
+dnl  The instructions can be omitted to just assert a flags condition with
+dnl  no extra calculation.  For example,
+dnl
+dnl         ASSERT(ne)
+dnl
+dnl  The condition can be omitted to just output the given instructions when
+dnl  assertion checking is wanted.  For example,
+dnl
+dnl         ASSERT(, `mr r11, r0')
+dnl
+dnl  Using a zero word for an illegal instruction is probably not ideal,
+dnl  since it marks the beginning of a traceback table in the 64-bit ABI.
+dnl  But assertions are only for development, so it doesn't matter too much.

+C  * Works for all sizes and alignment for 32-bit limbs.
+C  * Works for n >= 4 for 64-bit limbs; untested for smaller operands.
+C  * Current performance makes this pointless for 970
+
+C TODO
+C  * Might want to make variants when just one of the source operands needs
+C    vperm, and when neither needs it.  The latter runs 50% faster on 7400.
+C  * Idea: If the source operands are equally aligned, we could do the logops
+C    first, then vperm before storing!  That means we never need more than one
+C    vperm, ever!
+C  * Perhaps align `rp' after initial alignment loop?
+C  * Instead of having scalar code in the beginning and end, consider using
+C    read-modify-write vector code.
+C  * Software pipeline?  Hopefully not too important, this is hairy enough
+C    already.
+C  * At least be more clever about operand loading, i.e., load v operands before
+C    u operands, since v operands are sometimes negated.

+
+                    POWERPC-64 MPN SUBROUTINES
+
+
+This directory contains mpn functions for 64-bit PowerPC chips.
+
+
+CODE ORGANIZATION
+
+	mpn/powerpc64          mode-neutral code
+	mpn/powerpc64/mode32   code for mode32
+	mpn/powerpc64/mode64   code for mode64
+
+
+The mode32 and mode64 sub-directories contain code which is for use in the
+respective chip mode, 32 or 64.  The top-level directory is code that's
+unaffected by the mode.
+
+The "adde" instruction is the main difference between mode32 and mode64.  It
+operates on either on a 32-bit or 64-bit quantity according to the chip mode.
+Other instructions have an operand size in their opcode and hence don't vary.
+
+
+
+POWER3/PPC630 pipeline information:
+
+Decoding is 4-way + branch and issue is 8-way with some out-of-order
+capability.
+
+Functional units:
+LS1  - ld/st unit 1
+LS2  - ld/st unit 2
+FXU1 - integer unit 1, handles any simple integer instruction
+FXU2 - integer unit 2, handles any simple integer instruction
+FXU3 - integer unit 3, handles integer multiply and divide
+FPU1 - floating-point unit 1
+FPU2 - floating-point unit 2
+
+Memory:		  Any two memory operations can issue, but memory subsystem
+		  can sustain just one store per cycle.  No need for data
+		  prefetch; the hardware has very sophisticated prefetch logic.
+Simple integer:	  2 operations (such as add, rl*)
+Integer multiply: 1 operation every 9th cycle worst case; exact timing depends
+		  on 2nd operand's most significant bit position (10 bits per
+		  cycle).  Multiply unit is not pipelined, only one multiply
+		  operation in progress is allowed.
+Integer divide:	  ?
+Floating-point:	  Any plain 2 arithmetic instructions (such as fmul, fadd, and
+		  fmadd), latency 4 cycles.
+Floating-point divide:
+		  ?
+Floating-point square root:
+		  ?
+
+POWER3/PPC630 best possible times for the main loops:
+shift:	      1.5 cycles limited by integer unit contention.
+	      With 63 special loops, one for each shift count, we could
+	      reduce the needed integer instructions to 2, which would
+	      reduce the best possible time to 1 cycle.
+add/sub:      1.5 cycles, limited by ld/st unit contention.
+mul:	      18 cycles (average) unless floating-point operations are used,
+	      but that would only help for multiplies of perhaps 10 and more
+	      limbs.
+addmul/submul:Same situation as for mul.
+
+
+POWER4/PPC970 and POWER5 pipeline information:
+
+This is a very odd pipeline, it is basically a VLIW masquerading as a plain
+architecture.  Its issue rules are not made public, and since it is so weird,
+it is very hard to figure out any useful information from experimentation.
+An example:
+
+  A well-aligned loop with nop's take 3, 4, 6, 7, ... cycles.
+    3 cycles for  0,  1,  2,  3,  4,  5,  6,  7 nop's
+    4 cycles for  8,  9, 10, 11, 12, 13, 14, 15 nop's
+    6 cycles for 16, 17, 18, 19, 20, 21, 22, 23 nop's
+    7 cycles for 24, 25, 26, 27 nop's
+    8 cycles for 28, 29, 30, 31 nop's
+    ... continues regularly
+
+
+Functional units:
+LS1  - ld/st unit 1
+LS2  - ld/st unit 2
+FXU1 - integer unit 1, handles any integer instruction
+FXU2 - integer unit 2, handles any integer instruction
+FPU1 - floating-point unit 1
+FPU2 - floating-point unit 2
+
+While this is one integer unit less than POWER3/PPC630, the remaining units
+are more powerful; here they handle multiply and divide.
+
+Memory:		  2 ld/st.  Stores go to the L2 cache, which can sustain just
+		  one store per cycle.
+		  L1 load latency: to gregs 3-4 cycles, to fregs 5-6 cycles.
+		  Operations that modify the address register might be split
+		  to use also an integer issue slot.
+Simple integer:	  2 operations every cycle, latency 2.
+Integer multiply: 2 operations every 6th cycle, latency 7 cycles.
+Integer divide:	  ?
+Floating-point:	  Any plain 2 arithmetic instructions (such as fmul, fadd, and
+		  fmadd), latency 6 cycles.
+Floating-point divide:
+		  ?
+Floating-point square root:
+		  ?
+
+
+IDEAS
+
+*mul_1: Handling one limb using mulld/mulhdu and two limbs using floating-
+point operations should give performance of about 20 cycles for 3 limbs, or 7
+cycles/limb.
+
+We should probably split the single-limb operand in 32-bit chunks, and the
+multi-limb operand in 16-bit chunks, allowing us to accumulate well in fp
+registers.
+
+Problem is to get 32-bit or 16-bit words to the fp registers.  Only 64-bit fp
+memops copies bits without fiddling with them.  We might therefore need to
+load to integer registers with zero extension, store as 64 bits into temp
+space, and then load to fp regs.  Alternatively, load directly to fp space
+and add well-chosen constants to get cancellation.  (Other part after given by
+subsequent subtraction.)

+C  * Reduce register usage.  At least 4 register less can be used.
+C  * Unroll more.  8-way unrolling would bring us to 10 c/l, 16-way unrolling
+C    would bring us to 9 c/l.
+C  * The bdz insns for b1 and b2 will never branch,
+C  * Align things better, perhaps by moving things like pointer updates from

+C  * Check if (inner) loop alignment affects performance.
+C  * Could we schedule loads less in addmul_2/mul_2? That would save some regs
+C    and make the tail code more manageable.
+C  * Postpone some register saves to main loop.
+C  * Perhaps write more small operands (3x1, 3x2, 3x3) code.
+C  * Consider restoring rp,up after loop using arithmetic, eliminating rp2, up2.
+C    On the other hand, the current rp,up restore register are useful for OSP.
+C  * Do OSP. This should save a lot with the current deep addmul_2 pipeline.

+C TODO
+C  * Completely separate evn and odd code into two outer loops. Also consider
+C    unrolling these two outer loops and thereby eliminate all branches.
+C  * Avoid the reloading of u1 before every loop start.
+C  * Reduce register usage.
+C  * Consider getting rid of cy and instead load 3 u limbs, use addc+adde+adde.
+C  * Consider skewing conditional adjustments to allow mask creation with subfe
+C    like in the un=3 code. It might streamline the adjustments (or not).

+C NOTES
+C  * This is very crude, cleanup!
+C  * Try to reduce the number of needed live registers.
+C  * Rewrite for POWER6 to use 8 consecutive muls, not 2 groups of 4.  The
+C    cost will be more live registers.
+C  * Rewrite for POWER7 to use addmul_2 building blocks; this will reduce code
+C    size a lot and speed things up perhaps 25%.
+C  * Use computed goto in order to compress the code.
+C  * Implement a larger final corner.
+C  * Schedule callee-saves register saves into other insns.  This could save
+C    about 5 cycles/call.  (We cannot analogously optimise the restores, since
+C    the sqr_diag_addlsh1 loop has no wind-down code as currently written.)
+C  * Should the alternating std/adde sequences be split?  Some pipelines handle
+C    adde poorly, and might sequentialise all these instructions.
+C  * The sqr_diag_addlsh1 loop was written for POWER6 and its preferences for
+C    adjacent integer multiply insns.  Except for the multiply insns, the code
+C    was not carefully optimised for POWER6 or any other CPU.
+C  * Perform cross-jumping in sqr_diag_addlsh1's feed-in code, into the loop.

+
+There are 5 generations of 64-bit s390 processors, z900, z990, z9,
+z10, and z196.  The current GMP code was optimised for the two oldest,
+z900 and z990.
+
+
+mpn_copyi
+
+This code makes use of a loop around MVC.  It almost surely runs very
+close to optimally.  A small improvement could be done by using one
+MVC for size 256 bytes, now we use two (we use an extra MVC when
+copying any multiple of 256 bytes).
+
+
+mpn_copyd
+
+We have tried several feed-in variants here, branch tree, jump table
+and computed goto.  The fastest (on z990) turned out to be computed
+goto.
+
+An approach not tried is EX of LMG and STMG, modifying the register set
+on-the-fly.  Using that trick, we could completely avoid using
+separate feed-in paths.
+
+
+mpn_lshift, mpn_rshift
+
+The current code runs at pipeline decode bandwidth on z990.
+
+
+mpn_add_n, mpn_sub_n
+
+The current code is 4-way unrolled.  It should be unrolled more, at
+least 8x, in order to reach 2.5 c/l.
+
+
+mpn_mul_1, mpn_addmul_1, mpn_submul_1
+
+The current code is very naive, but due to the non-pipelined nature of
+MLGR on z900 and z990, more sophisticated code would not gain much.
+
+On z10 one would need to cluster at least 4 MLGR together, in order to
+reduce stalling.
+
+On z196, one surely want to use unrolling and pipelining, to perhaps
+reach around 12 c/l.  A major issue here and on z10 is ALCGR's 3 cycle
+stalling.
+
+
+mpn_mul_2, mpn_addmul_2
+
+At least for older machines (z900, z990) with very slow MLGR, we
+should use Karatsuba's algorithm on 2-limb units, making mul_2 and
+addmul_2 the main multiplication primitives.  The newer machines might
+benefit less from this approach, perhaps in particular z10, where MLGR
+clustering is more important.
+
+With Karatsuba, one could hope for around 16 cycles per accumulated
+128 cross product, on z990.

+C NOTES
+C  * This uses discrete loads and stores in a software pipeline.  Using lmg and
+C    stmg is not faster.
+C  * One could assume more pipelining could approach 2.5 c/l, but we have not
+C    found any 8-way loop that runs better than the current 4-way loop.
+C  * Consider using the same feed-in code for 1 <= n <= 3 as for n mod 4,
+C    similarly to the x86_64 sqr_basecase feed-in.

+C  * Clean up.
+C  * Stop iterating addmul_1 loop at latest for n = 2, implement longer tail.
+C    This will ask for basecase handling of n = 3.
+C  * Update counters and pointers more straightforwardly, possibly lowering
+C    register usage.
+C  * Should we use this allocation-free style for more sqr_basecase asm
+C    implementations?  The only disadvantage is that it requires R != U.
+C  * Replace loops by faster code.  The mul_1 and addmul_1 loops could be sped
+C    up by about 10%.  The sqr_diag_addlsh1 loop could probably be sped up even

+
+This directory contains mpn functions for various SPARC chips.  Code that
+runs only on version 8 SPARC implementations, is in the v8 subdirectory.
+
+RELEVANT OPTIMIZATION ISSUES
+
+  Load and Store timing
+
+On most early SPARC implementations, the ST instructions takes multiple
+cycles, while a STD takes just a single cycle more than an ST.  For the CPUs
+in SPARCstation I and II, the times are 3 and 4 cycles, respectively.
+Therefore, combining two ST instructions into a STD when possible is a
+significant optimization.
+
+Later SPARC implementations have single cycle ST.
+
+For SuperSPARC, we can perform just one memory instruction per cycle, even
+if up to two integer instructions can be executed in its pipeline.  For
+programs that perform so many memory operations that there are not enough
+non-memory operations to issue in parallel with all memory operations, using
+LDD and STD when possible helps.
+
+UltraSPARC-1/2 has very slow integer multiplication.  In the v9 subdirectory,
+we therefore use floating-point multiplication.
+
+STATUS
+
+1. On a SuperSPARC, mpn_lshift and mpn_rshift run at 3 cycles/limb, or 2.5
+   cycles/limb asymptotically.  We could optimize speed for special counts
+   by using ADDXCC.
+
+2. On a SuperSPARC, mpn_add_n and mpn_sub_n runs at 2.5 cycles/limb, or 2
+   cycles/limb asymptotically.
+
+3. mpn_mul_1 runs at what is believed to be optimal speed.
+
+4. On SuperSPARC, mpn_addmul_1 and mpn_submul_1 could both be improved by a
+   cycle by avoiding one of the add instructions.  See a29k/addmul_1.
+
+The speed of the code for other SPARC implementations is uncertain.

+C Algorithm: We use two floating-point multiplies per limb product, with the
+C invariant v operand split into two 16-bit pieces, and the u operand split
+C into 32-bit pieces.  We convert the two 48-bit products and transfer them to
+C the integer unit.
+
+C		   cycles/limb
+C UltraSPARC 1&2:     6.5
+C UltraSPARC 3:	      ?
+
+C Possible optimizations:
+C   1. Combine 32-bit memory operations into 64-bit operations.  Since we're
+C      memory bandwidth limited, this could save 1.5 cycles/limb.
+C   2. Unroll the inner loop.  Since we already use alternate temporary areas,
+C      it is very straightforward to unroll, using an exit branch midways.
+C      Unrolling would allow deeper scheduling which could improve speed for L2
+C      cache case.
+C   3. For mpn_mul_1: Use more alternating temp areas.  The std'es and ldx'es
+C      aren't sufficiently apart-scheduled with just two temp areas.
+C   4. Specialize for particular v values.  If its upper 16 bits are zero, we
+C      could save many operations.

+C Algorithm: We use two floating-point multiplies per limb product, with the
+C invariant v operand split into two 16-bit pieces, and the u operand split
+C into 32-bit pieces.  We convert the two 48-bit products and transfer them to
+C the integer unit.
+
+C		   cycles/limb
+C UltraSPARC 1&2:     6.5
+C UltraSPARC 3:	      ?
+
+C Possible optimizations:
+C   1. Combine 32-bit memory operations into 64-bit operations.  Since we're
+C      memory bandwidth limited, this could save 1.5 cycles/limb.
+C   2. Unroll the inner loop.  Since we already use alternate temporary areas,
+C      it is very straightforward to unroll, using an exit branch midways.
+C      Unrolling would allow deeper scheduling which could improve speed for L2
+C      cache case.
+C   3. For mpn_mul_1: Use more alternating temp areas.  The std'es and ldx'es
+C      aren't sufficiently apart-scheduled with just two temp areas.
+C   4. Specialize for particular v values.  If its upper 16 bits are zero, we
+C      could save many operations.

+C This code uses a very deep software pipeline, due to the need for moving data
+C forth and back between the integer registers and floating-point registers.
+C
+C A VIS variant of this code would make the pipeline less deep, since the
+C masking now done in the integer unit could take place in the floating-point
+C unit using the FAND instruction.  It would be possible to save several cycles
+C too.
+C
+C On UltraSPARC 1 and 2, this code runs at 11 cycles/limb from the Dcache and
+C not much slower from the Ecache.  It would perhaps be possible to shave off
+C one cycle, but not easily.  We cannot do better than 10 cycles/limb with the
+C used instructions, since we have 10 memory operations per limb.  But a VIS
+C variant could run three cycles faster than the corresponding non-VIS code.
+
+C This is non-pipelined code showing the algorithm:

+C Algorithm: We use two floating-point multiplies per limb product, with the
+C invariant v operand split into two 16-bit pieces, and the u operand split
+C into 32-bit pieces.  We convert the two 48-bit products and transfer them to
+C the integer unit.
+
+C		   cycles/limb
+C UltraSPARC 1&2:     6.5
+C UltraSPARC 3:	      ?
+
+C Possible optimizations:
+C   1. Combine 32-bit memory operations into 64-bit operations.  Since we're
+C      memory bandwidth limited, this could save 1.5 cycles/limb.
+C   2. Unroll the inner loop.  Since we already use alternate temporary areas,
+C      it is very straightforward to unroll, using an exit branch midways.
+C      Unrolling would allow deeper scheduling which could improve speed for L2
+C      cache case.
+C   3. For mpn_mul_1: Use more alternating temp areas.  The std'es and ldx'es
+C      aren't sufficiently apart-scheduled with just two temp areas.
+C   4. Specialize for particular v values.  If its upper 16 bits are zero, we
+C      could save many operations.

+This directory contains mpn functions for 64-bit V9 SPARC
+
+RELEVANT OPTIMIZATION ISSUES
+
+Notation:
+  IANY = shift/add/sub/logical/sethi
+  IADDLOG = add/sub/logical/sethi
+  MEM = ld*/st*
+  FA = fadd*/fsub*/f*to*/fmov*
+  FM = fmul*
+
+UltraSPARC can issue four instructions per cycle, with these restrictions:
+* Two IANY instructions, but only one of these may be a shift.  If there is a
+  shift and an IANY instruction, the shift must precede the IANY instruction.
+* One FA.
+* One FM.
+* One branch.
+* One MEM.
+* IANY/IADDLOG/MEM must be insn 1, 2, or 3 in an issue bundle.  Taken branches
+  should not be in slot 4, since that makes the delay insn come from separate
+  bundle.
+* If two IANY/IADDLOG instructions are to be executed in the same cycle and one
+  of these is setting the condition codes, that instruction must be the second
+  one.
+
+To summarize, ignoring branches, these are the bundles that can reach the peak
+execution speed:
+
+insn1	iany	iany	mem	iany	iany	mem	iany	iany	mem
+insn2	iaddlog	mem	iany	mem	iaddlog	iany	mem	iaddlog	iany
+insn3	mem	iaddlog	iaddlog	fa	fa	fa	fm	fm	fm
+insn4	fa/fm	fa/fm	fa/fm	fm	fm	fm	fa	fa	fa
+
+The 64-bit integer multiply instruction mulx takes from 5 cycles to 35 cycles,
+depending on the position of the most significant bit of the first source
+operand.  When used for 32x32->64 multiplication, it needs 20 cycles.
+Furthermore, it stalls the processor while executing.  We stay away from that
+instruction, and instead use floating-point operations.
+
+Floating-point add and multiply units are fully pipelined.  The latency for
+UltraSPARC-1/2 is 3 cycles and for UltraSPARC-3 it is 4 cycles.
+
+Integer conditional move instructions cannot dual-issue with other integer
+instructions.  No conditional move can issue 1-5 cycles after a load.  (This
+might have been fixed for UltraSPARC-3.)
+
+The UltraSPARC-3 pipeline is very simular to the one of UltraSPARC-1/2 , but is
+somewhat slower.  Branches execute slower, and there may be other new stalls.
+But integer multiply doesn't stall the entire CPU and also has a much lower
+latency.  But it's still not pipelined, and thus useless for our needs.
+
+STATUS
+
+* mpn_lshift, mpn_rshift: The current code runs at 2.0 cycles/limb on
+  UltraSPARC-1/2 and 2.65 on UltraSPARC-3.  For UltraSPARC-1/2, the IEU0
+  functional unit is saturated with shifts.
+
+* mpn_add_n, mpn_sub_n: The current code runs at 4 cycles/limb on
+  UltraSPARC-1/2 and 4.5 cycles/limb on UltraSPARC-3.  The 4 instruction
+  recurrency is the speed limiter.
+
+* mpn_addmul_1: The current code runs at 14 cycles/limb asymptotically on
+  UltraSPARC-1/2 and 17.5 cycles/limb on UltraSPARC-3.  On UltraSPARC-1/2, the
+  code sustains 4 instructions/cycle.  It might be possible to invent a better
+  way of summing the intermediate 49-bit operands, but it is unlikely that it
+  will save enough instructions to save an entire cycle.
+
+  The load-use of the u operand is not enough scheduled for good L2 cache
+  performance.  The UltraSPARC-1/2 L1 cache is direct mapped, and since we use
+  temporary stack slots that will conflict with the u and r operands, we miss
+  to L2 very often.  The load-use of the std/ldx pairs via the stack are
+  perhaps over-scheduled.
+
+  It would be possible to save two instructions: (1) The mov could be avoided
+  if the std/ldx were less scheduled.  (2) The ldx of the r operand could be
+  split into two ld instructions, saving the shifts/masks.
+
+  It should be possible to reach 14 cycles/limb for UltraSPARC-3 if the fp
+  operations where rescheduled for this processor's 4-cycle latency.
+
+* mpn_mul_1: The current code is a straightforward edit of the mpn_addmul_1
+  code.  It would be possible to shave one or two cycles from it, with some
+  labour.
+
+* mpn_submul_1: Simpleminded code just calling mpn_mul_1 + mpn_sub_n.  This
+  means that it runs at 18 cycles/limb on UltraSPARC-1/2 and 23 cycles/limb on
+  UltraSPARC-3.  It would be possible to either match the mpn_addmul_1
+  performance, or in the worst case use one more instruction group.
+
+* US1/US2 cache conflict resolving.  The direct mapped L1 date cache of US1/US2
+  is a problem for mul_1, addmul_1 (and a prospective submul_1).  We should
+  allocate a larger cache area, and put the stack temp area in a place that
+  doesn't cause cache conflicts.

+   cross-products involving the high 32-bits of the divisor, that being zero
+   of course.  Secondly umul_ppmm_lowequal and umul_ppmm_half_lowequal save
+   one mulx (each) knowing the low of q*d is equal to the input limb l.
+
+   For size==1, a simple udivx is used.  This is faster than calculating an
+   inverse.
+
+   For a 32-bit divisor and small sizes, an attempt was made at a simple
+   udivx loop (two per 64-bit limb), but it turned out to be slower than
+   mul-by-inverse.  At size==2 the inverse is about 260 cycles total
+   compared to a udivx at 291.  Perhaps the latter would suit when size==2
+   but the high 32-bits of the second limb is zero (saving one udivx), but
+   it doesn't seem worth a special case just for that.  */

+
+
+/* This implementation reduces the number of multiplies done, knowing that
+   on ultrasparc 1 and 2 the mulx instruction stalls the whole chip.
+
+   The key idea is to use the fact that the low limb of q*d equals l, this
+   being the whole purpose of the q calculated.  It means there's no need to
+   calculate the lowest 32x32->64 part of the q*d, instead it can be
+   inferred from l and the other three 32x32->64 parts.  See sparc64.h for
+   details.
+
+   When d is 32-bits, the same applies, but in this case there's only one
+   other 32x32->64 part (ie. HIGH(q)*d).
+
+   The net effect is that for 64-bit divisor each limb is 4 mulx, or for
+   32-bit divisor each is 2 mulx.
+
+   Enhancements:
+
+   No doubt this could be done in assembler, if that helped the scheduling,
+   or perhaps guaranteed good code irrespective of the compiler.
+
+   Alternatives:
+
+   It might be possibly to use floating point.  The loop is dominated by
+   multiply latency, so not sure if floats would improve that.  One
+   possibility would be to take two limbs at a time, with a 128 bit inverse,
+   if there's enough registers, which could effectively use float throughput
+   to reduce total latency across two limbs.  */

+C		   cycles/limb
+C UltraSPARC 1&2:     14
+C UltraSPARC 3:	      17.5
+
+C Algorithm: We use eight floating-point multiplies per limb product, with the
+C invariant v operand split into four 16-bit pieces, and the up operand split
+C into 32-bit pieces.  We sum pairs of 48-bit partial products using
+C floating-point add, then convert the four 49-bit product-sums and transfer
+C them to the integer unit.
+
+C Possible optimizations:
+C   0. Rewrite to use algorithm of mpn_addmul_2.
+C   1. Align the stack area where we transfer the four 49-bit product-sums
+C      to a 32-byte boundary.  That would minimize the cache collision.
+C      (UltraSPARC-1/2 use a direct-mapped cache.)  (Perhaps even better would
+C      be to align the area to map to the area immediately before up?)
+C   2. Sum the 4 49-bit quantities using 32-bit operations, as in the
+C      develop mpn_addmul_2.  This would save many integer instructions.
+C   3. Unrolling.  Questionable if it is worth the code expansion, given that
+C      it could only save 1 cycle/limb.
+C   4. Specialize for particular v values.  If its upper 32 bits are zero, we
+C      could save many operations, in the FPU (fmuld), but more so in the IEU
+C      since we'll be summing 48-bit quantities, which might be simpler.
+C   5. Ideally, we should schedule the f2/f3 and f4/f5 RAW further apart, and
+C      the i00,i16,i32,i48 RAW less apart.  The latter apart-scheduling should
+C      not be greater than needed for L2 cache latency, and also not so great
+C      that i16 needs to be copied.
+C   6. Avoid performing mem+fa+fm in the same cycle, at least not when we want
+C      to get high IEU bandwidth.  (12 of the 14 cycles will be free for 2 IEU
+C      ops.)
+
+C Instruction classification (as per UltraSPARC-1/2 functional units):
+C    8 FM
+C   10 FA
+C   12 MEM
+C   10 ISHIFT + 14 IADDLOG
+C    1 BRANCH
+C   55 insns totally (plus one mov insn that should be optimized out)
+
+C The loop executes 56 instructions in 14 cycles on UltraSPARC-1/2, i.e we
+C sustain the peak execution rate of 4 instructions/cycle.

+C UltraSPARC 1&2:      9
+C UltraSPARC 3:       10
+
+C Algorithm: We use 16 floating-point multiplies per limb product, with the
+C 2-limb v operand split into eight 16-bit pieces, and the n-limb u operand
+C split into 32-bit pieces.  We sum four 48-bit partial products using
+C floating-point add, then convert the resulting four 50-bit quantities and
+C transfer them to the integer unit.
+
+C Possible optimizations:
+C   1. Align the stack area where we transfer the four 50-bit product-sums
+C      to a 32-byte boundary.  That would minimize the cache collision.
+C      (UltraSPARC-1/2 use a direct-mapped cache.)  (Perhaps even better would
+C      be to align the area to map to the area immediately before up?)
+C   2. Perform two of the fp->int conversions with integer instructions.  We
+C      can get almost ten free IEU slots, if we clean up bookkeeping and the
+C      silly carry-limb code.
+C   3. For an mpn_addmul_1 based on this, we need to fix the silly carry-limb
+C      code.
+
+C OSP (Overlapping software pipeline) version of mpn_mul_basecase:
+C Operand swap will require 8 LDDA and 8 FXTOD, which will mean 8 cycles.
+C FI	= 20
+C L	=  9 x un * vn
+C WDFI	= 10 x vn / 2
+C WD	= 4
+
+C Instruction classification (as per UltraSPARC functional units).
+C Assuming silly carry code is fixed.  Includes bookkeeping.

+C UltraSPARC 1&2:     14
+C UltraSPARC 3:	      18.5
+
+C Algorithm: We use eight floating-point multiplies per limb product, with the
+C invariant v operand split into four 16-bit pieces, and the s1 operand split
+C into 32-bit pieces.  We sum pairs of 48-bit partial products using
+C floating-point add, then convert the four 49-bit product-sums and transfer
+C them to the integer unit.
+
+C Possible optimizations:
+C   1. Align the stack area where we transfer the four 49-bit product-sums
+C      to a 32-byte boundary.  That would minimize the cache collision.
+C      (UltraSPARC-1/2 use a direct-mapped cache.)  (Perhaps even better would
+C      be to align the area to map to the area immediately before s1?)
+C   2. Sum the 4 49-bit quantities using 32-bit operations, as in the
+C      develop mpn_addmul_2.  This would save many integer instructions.
+C   3. Unrolling.  Questionable if it is worth the code expansion, given that
+C      it could only save 1 cycle/limb.
+C   4. Specialize for particular v values.  If its upper 32 bits are zero, we
+C      could save many operations, in the FPU (fmuld), but more so in the IEU
+C      since we'll be summing 48-bit quantities, which might be simpler.
+C   5. Ideally, we should schedule the f2/f3 and f4/f5 RAW further apart, and
+C      the i00,i16,i32,i48 RAW less apart.  The latter apart-scheduling should
+C      not be greater than needed for L2 cache latency, and also not so great
+C      that i16 needs to be copied.
+C   6. Avoid performing mem+fa+fm in the same cycle, at least not when we want
+C      to get high IEU bandwidth.  (12 of the 14 cycles will be free for 2 IEU
+C      ops.)
+
+C Instruction classification (as per UltraSPARC-1/2 functional units):
+C    8 FM
+C   10 FA
+C   11 MEM
+C   9 ISHIFT + 10? IADDLOG
+C    1 BRANCH
+C   49 insns totally (plus three mov insns that should be optimized out)
+
+C The loop executes 53 instructions in 14 cycles on UltraSPARC-1/2, i.e we
+C sustain 3.79 instructions/cycle.

+C		   cycles/limb
+C UltraSPARC 1&2:     22
+C UltraSPARC 3:	      36
+
+C This was generated by the Sun C compiler.  It runs at 22 cycles/limb on the
+C UltraSPARC-1/2, three cycles slower than theoretically possible for optimal
+C code using the same algorithm.  For 1-3 limbs, a special loop was generated,
+C which causes performance problems in particular for 2 and 3 limbs.
+C Ultimately, this should be replaced by hand-written code in the same software
+C pipeline style as e.g., addmul_1.asm.

+C The code is reasonably scheduled but also relies on OoO.  There was hope that
+C this could run at around 3.0 and 3.5 c/l respectively, on T4.  Two cycles per
+C iteration needs to be removed.
+C
+C We could almost use 2-way unrolling, but currently the wN registers live too
+C long.  By changing add x,w1,w1 to add x,w1,w0, i.e. migrate the values down-
+C wards, 2-way unrolling should become possible.  With n-indexed addressing it
+C should run no slower.
+C
+C The rp loads to g1/g3 are very much over-scheduled.  Presumably, they could
+C be postponed a full way, and then just one register could be used.

+C (a xor not b) = (not (a xor b)) which equals (not (a or b)) when (a and b) =
+C 0 as it is in our usage.  This gives us the ones complement for free.
+C Unfortunately, the same trick will not work for rsblsh_n, which will instead
+C require a separate negation.

+
+
+This directory contains mpn functions for various 80x86 chips.

+
+
+The top-level x86 directory contains blended style code, meant to be
+reasonable on all x86s.
+
+
+
+STATUS
+
+The code is well-optimized for AMD and Intel chips, but there's nothing
+specific for Cyrix chips, nor for actual 80386 and 80486 chips.
+
+
+
+ASM FILES
+
+The x86 .asm files are BSD style assembler code, first put through m4 for
+macro processing.  The generic mpn/asm-defs.m4 is used, together with
+mpn/x86/x86-defs.m4.  See comments in those files.
+
+The code is meant for use with GNU "gas" or a system "as".  There's no
+support for assemblers that demand Intel style code.
+
+
+
+STACK FRAME
+
+m4 macros are used to define the parameters passed on the stack, and these
+act like comments on what the stack frame looks like too.  For example,
+mpn_mul_1() has the following.
+
+        defframe(PARAM_MULTIPLIER, 16)
+        defframe(PARAM_SIZE,       12)
+        defframe(PARAM_SRC,         8)
+        defframe(PARAM_DST,         4)
+
+PARAM_MULTIPLIER becomes `FRAME+16(%esp)', and the others similarly.  The
+return address is at offset 0, but there's not normally any need to access
+that.
+
+FRAME is redefined as necessary through the code so it's the number of bytes
+pushed on the stack, and hence the offsets in the parameter macros stay
+correct.  At the start of a routine FRAME should be zero.
+
+        deflit(`FRAME',0)
+	...
+	deflit(`FRAME',4)
+	...
+	deflit(`FRAME',8)
+	...
+
+Helper macros FRAME_pushl(), FRAME_popl(), FRAME_addl_esp() and
+FRAME_subl_esp() exist to adjust FRAME for the effect of those instructions,
+and can be used instead of explicit definitions if preferred.
+defframe_pushl() is a combination FRAME_pushl() and defframe().
+
+There's generally some slackness in redefining FRAME.  If new values aren't
+going to get used then the redefinitions are omitted to keep from cluttering
+up the code.  This happens for instance at the end of a routine, where there
+might be just four pops and then a ret, so FRAME isn't getting used.
+
+Local variables and saved registers can be similarly defined, with negative
+offsets representing stack space below the initial stack pointer.  For
+example,
+
+	defframe(SAVE_ESI,   -4)
+	defframe(SAVE_EDI,   -8)
+	defframe(VAR_COUNTER,-12)
+
+	deflit(STACK_SPACE, 12)
+
+Here STACK_SPACE gets used in a "subl $STACK_SPACE, %esp" to allocate the
+space, and that instruction must be followed by a redefinition of FRAME
+(setting it equal to STACK_SPACE) to reflect the change in %esp.
+
+Definitions for pushed registers are only put in when they're going to be
+used.  If registers are just saved and restored with pushes and pops then
+definitions aren't made.
+
+
+
+ASSEMBLER EXPRESSIONS
+
+Only addition and subtraction seem to be universally available, certainly
+that's all the Solaris 8 "as" seems to accept.  If expressions are wanted
+then m4 eval() should be used.
+
+In particular note that a "/" anywhere in a line starts a comment in Solaris
+"as", and in some configurations of gas too.
+
+	addl	$32/2, %eax           <-- wrong
+
+	addl	$eval(32/2), %eax     <-- right
+
+Binutils gas/config/tc-i386.c has a choice between "/" being a comment
+anywhere in a line, or only at the start.  FreeBSD patches 2.9.1 to select
+the latter, and from 2.9.5 it's the default for GNU/Linux too.
+
+
+
+ASSEMBLER COMMENTS
+
+Solaris "as" doesn't support "#" commenting, using /* */ instead.  For that
+reason "C" commenting is used (see asm-defs.m4) and the intermediate ".s"
+files have no comments.
+
+Any comments before include(`../config.m4') must use m4 "dnl", since it's
+only after the include that "C" is available.  By convention "dnl" is also
+used for comments about m4 macros.
+
+
+
+TEMPORARY LABELS
+
+Temporary numbered labels like "1:" used as "1f" or "1b" are available in
+"gas" and Solaris "as", but not in SCO "as".  Normal L() labels should be
+used instead, possibly with a counter to make them unique, see jadcl0() in
+x86-defs.m4 for instance.  A separate counter for each macro makes it
+possible to nest them, for instance movl_text_address() can be used within
+an ASSERT().
+
+"1:" etc must be avoided in gcc __asm__ blocks too.  "%=" for generating a
+unique number looks like a good alternative, but is that actually a
+documented feature?  In any case this problem doesn't currently arise.
+
+
+
+ZERO DISPLACEMENTS
+
+In a couple of places addressing modes like 0(%ebx) with a byte-sized zero
+displacement are wanted, rather than (%ebx) with no displacement.  These are
+either for computed jumps or to get desirable code alignment.  Explicit
+.byte sequences are used to ensure the assembler doesn't turn 0(%ebx) into
+(%ebx).  The Zdisp() macro in x86-defs.m4 is used for this.
+
+Current gas 2.9.5 or recent 2.9.1 leave 0(%ebx) as written, but old gas
+1.92.3 changes it.  In general changing would be the sort of "optimization"
+an assembler might perform, hence explicit ".byte"s are used where
+necessary.
+
+
+
+SHLD/SHRD INSTRUCTIONS
+
+The %cl count forms of double shift instructions like "shldl %cl,%eax,%ebx"
+must be written "shldl %eax,%ebx" for some assemblers.  gas takes either,
+Solaris "as" doesn't allow %cl, gcc generates %cl for gas and NeXT (which is
+gas), and omits %cl elsewhere.
+
+For GMP an autoconf test GMP_ASM_X86_SHLDL_CL is used to determine whether
+%cl should be used, and the macros shldl, shrdl, shldw and shrdw in
+mpn/x86/x86-defs.m4 pass through or omit %cl as necessary.  See the comments
+with those macros for usage.
+
+
+
+IMUL INSTRUCTION
+
+GCC config/i386/i386.md (cvs rev 1.187, 21 Oct 00) under *mulsi3_1 notes
+that the following two forms produce identical object code
+
+	imul	$12, %eax
+	imul	$12, %eax, %eax
+
+but that the former isn't accepted by some assemblers, in particular the SCO
+OSR5 COFF assembler.  GMP follows GCC and uses only the latter form.
+
+(This applies only to immediate operands, the three operand form is only
+valid with an immediate.)
+
+
+
+DIRECTION FLAG
+
+The x86 calling conventions say that the direction flag should be clear at
+function entry and exit.  (See iBCS2 and SVR4 ABI books, references below.)
+Although this has been so since the year dot, it's not absolutely clear
+whether it's universally respected.  Since it's better to be safe than
+sorry, GMP follows glibc and does a "cld" if it depends on the direction
+flag being clear.  This happens only in a few places.
+
+
+
+POSITION INDEPENDENT CODE
+
+  Coding Style
+
+    Defining the symbol PIC in m4 processing selects SVR4 / ELF style
+    position independent code.  This is necessary for shared libraries
+    because they can be mapped into different processes at different virtual
+    addresses.  Actually, relocations are allowed but text pages with
+    relocations aren't shared, defeating the purpose of a shared library.
+
+    The GOT is used to access global data, and the PLT is used for
+    functions.  The use of the PLT adds a fixed cost to every function call,
+    and the GOT adds a cost to any function accessing global variables.
+    These are small but might be noticeable when working with small
+    operands.
+
+  Scope
+
+    It's intended, as a matter of policy, that references within libgmp are
+    resolved within libgmp.  Certainly there's no need for an application to
+    replace any internals, and we take the view that there's no value in an
+    application subverting anything documented either.
+
+    Resolving references within libgmp in theory means calls can be made with a
+    plain PC-relative call instruction, which is faster and smaller than going
+    through the PLT, and data references can be similarly PC-relative, saving a
+    GOT entry and fetch from there.  Unfortunately the normal linker behaviour
+    doesn't allow us to do this.
+
+    By default an R_386_PC32 PC-relative reference, either for a call or for
+    data, is left in libgmp.so by the linker so that it can be resolved at
+    runtime to a location in the application or another shared library.  This
+    means a text segment relocation which we don't want.
+
+  -Bsymbolic
+
+    Under the "-Bsymbolic" option, the linker resolves references to symbols
+    within libgmp.so.  This gives us the desired effect for R_386_PC32,
+    ie. it's resolved at link time.  It also resolves R_386_PLT32 calls
+    directly to their target without creating a PLT entry (though if this is
+    done to normal compiler-generated code it still leaves a setup of %ebx
+    to _GLOBAL_OFFSET_TABLE_ which may then be unnecessary).
+
+    Unfortunately -Bsymbolic does bad things to global variables defined in
+    a shared library but accessed by non-PIC code from the mainline (or a
+    static library).
+
+    The problem is that the mainline needs a fixed data address to avoid
+    text segment relocations, so space is allocated in its data segment and
+    the value from the variable is copied from the shared library's data
+    segment when the library is loaded.  Under -Bsymbolic, however,
+    references in the shared library are then resolved still to the shared
+    library data area.  Not surprisingly it bombs badly to have mainline
+    code and library code accessing different locations for what should be
+    one variable.
+
+    Note that this -Bsymbolic effect for the shared library is not just for
+    R_386_PC32 offsets which might have been cooked up in assembler, but is
+    done also for the contents of GOT entries.  -Bsymbolic simply applies a
+    general rule that symbols are resolved first from the local module.
+
+  Visibility Attributes
+
+    GCC __attribute__ ((visibility ("protected"))), which is available in
+    recent versions, eg. 3.3, is probably what we'd like to use.  It makes
+    gcc generate plain PC-relative calls to indicated functions, and directs
+    the linker to resolve references to the given function within the link
+    module.
+
+    Unfortunately, as of debian binutils 2.13.90.0.16 at least, the
+    resulting libgmp.so comes out with text segment relocations, references
+    are not resolved at link time.  If the gcc description is to be believed
+    this is this not how it should work.  If a symbol cannot be overridden
+    by another module then surely references within that module can be
+    resolved immediately (ie. at link time).
+
+  Present
+
+    In any case, all this means that we have no optimizations we can
+    usefully make to function or variable usages, neither for assembler nor
+    C code.  Perhaps in the future the visibility attribute will work as
+    we'd like.
+
+
+
+
+GLOBAL OFFSET TABLE
+
+The magic _GLOBAL_OFFSET_TABLE_ used by code establishing the address of the
+GOT sometimes requires an extra underscore prefix.  SVR4 systems and NetBSD
+don't need a prefix, OpenBSD does need one.  Note that NetBSD and OpenBSD
+are both a.out underscore systems, so the prefix for _GLOBAL_OFFSET_TABLE_
+is not simply the same as the prefix for ordinary globals.
+
+In any case in the asm code we write _GLOBAL_OFFSET_TABLE_ and let a macro
+in x86-defs.m4 add an extra underscore if required (according to a configure
+test).
+
+Old gas 1.92.3 which comes with FreeBSD 2.2.8 gets a segmentation fault when
+asked to assemble the following,
+
+        L1:
+            addl  $_GLOBAL_OFFSET_TABLE_+[.-L1], %ebx
+
+It seems that using the label in the same instruction it refers to is the
+problem, since a nop in between works.  But the simplest workaround is to
+follow gcc and omit the +[.-L1] since it does nothing,
+
+            addl  $_GLOBAL_OFFSET_TABLE_, %ebx
+
+Current gas 2.10 generates incorrect object code when %eax is used in such a
+construction (with or without +[.-L1]),
+
+            addl  $_GLOBAL_OFFSET_TABLE_, %eax
+
+The R_386_GOTPC gets a displacement of 2 rather than the 1 appropriate for
+the 1 byte opcode of "addl $n,%eax".  The best workaround is just to use any
+other register, since then it's a two byte opcode+mod/rm.  GCC for example
+always uses %ebx (which is needed for calls through the PLT).
+
+A similar problem occurs in an leal (again with or without a +[.-L1]),
+
+            leal  _GLOBAL_OFFSET_TABLE_(%edi), %ebx
+
+This time the R_386_GOTPC gets a displacement of 0 rather than the 2
+appropriate for the opcode and mod/rm, making this form unusable.
+
+
+
+
+SIMPLE LOOPS
+
+The overheads in setting up for an unrolled loop can mean that at small
+sizes a simple loop is faster.  Making small sizes go fast is important,
+even if it adds a cycle or two to bigger sizes.  To this end various
+routines choose between a simple loop and an unrolled loop according to
+operand size.  The path to the simple loop, or to special case code for
+small sizes, is always as fast as possible.
+
+Adding a simple loop requires a conditional jump to choose between the
+simple and unrolled code.  The size of a branch misprediction penalty
+affects whether a simple loop is worthwhile.
+
+The convention is for an m4 definition UNROLL_THRESHOLD to set the crossover
+point, with sizes < UNROLL_THRESHOLD using the simple loop, sizes >=
+UNROLL_THRESHOLD using the unrolled loop.  If position independent code adds
+a couple of cycles to an unrolled loop setup, the threshold will vary with
+PIC or non-PIC.  Something like the following is typical.
+
+	deflit(UNROLL_THRESHOLD, ifdef(`PIC',10,8))
+
+There's no automated way to determine the threshold.  Setting it to a small
+value and then to a big value makes it possible to measure the simple and
+unrolled loops each over a range of sizes, from which the crossover point
+can be determined.  Alternately, just adjust the threshold up or down until
+there's no more speedups.
+
+
+
+UNROLLED LOOP CODING
+
+The x86 addressing modes allow a byte displacement of -128 to +127, making
+it possible to access 256 bytes, which is 64 limbs, without adjusting
+pointer registers within the loop.  Dword sized displacements can be used
+too, but they increase code size, and unrolling to 64 ought to be enough.
+
+When unrolling to the full 64 limbs/loop, the limb at the top of the loop
+will have a displacement of -128, so pointers have to have a corresponding
++128 added before entering the loop.  When unrolling to 32 limbs/loop
+displacements 0 to 127 can be used with 0 at the top of the loop and no
+adjustment needed to the pointers.
+
+Where 64 limbs/loop is supported, the +128 adjustment is done only when 64
+limbs/loop is selected.  Usually the gain in speed using 64 instead of 32 or
+16 is small, so support for 64 limbs/loop is generally only for comparison.
+
+
+
+COMPUTED JUMPS
+
+When working from least significant limb to most significant limb (most
+routines) the computed jump and pointer calculations in preparation for an
+unrolled loop are as follows.
+
+	S = operand size in limbs
+	N = number of limbs per loop (UNROLL_COUNT)
+	L = log2 of unrolling (UNROLL_LOG2)
+	M = mask for unrolling (UNROLL_MASK)
+	C = code bytes per limb in the loop
+	B = bytes per limb (4 for x86)
+
+	computed jump            (-S & M) * C + entrypoint
+	subtract from pointers   (-S & M) * B
+	initial loop counter     (S-1) >> L
+	displacements            0 to B*(N-1)
+
+The loop counter is decremented at the end of each loop, and the looping
+stops when the decrement takes the counter to -1.  The displacements are for
+the addressing accessing each limb, eg. a load with "movl disp(%ebx), %eax".
+
+Usually the multiply by "C" can be handled without an imul, using instead an
+leal, or a shift and subtract.
+
+When working from most significant to least significant limb (eg. mpn_lshift
+and mpn_copyd), the calculations change as follows.
+
+	add to pointers          (-S & M) * B
+	displacements            0 to -B*(N-1)
+
+
+
+OLD GAS 1.92.3
+
+This version comes with FreeBSD 2.2.8 and has a couple of gremlins that
+affect GMP code.
+
+Firstly, an expression involving two forward references to labels comes out
+as zero.  For example,
+
+		addl	$bar-foo, %eax
+	foo:
+		nop
+	bar:
+
+This should lead to "addl $1, %eax", but it comes out as "addl $0, %eax".
+When only one forward reference is involved, it works correctly, as for
+example,
+
+	foo:
+		addl	$bar-foo, %eax
+		nop
+	bar:
+
+Secondly, an expression involving two labels can't be used as the
+displacement for an leal.  For example,
+
+	foo:
+		nop
+	bar:
+		leal	bar-foo(%eax,%ebx,8), %ecx
+
+A slightly cryptic error is given, "Unimplemented segment type 0 in
+parse_operand".  When only one label is used it's ok, and the label can be a
+forward reference too, as for example,
+
+		leal	foo(%eax,%ebx,8), %ecx
+		nop
+	foo:
+
+These problems only affect PIC computed jump calculations.  The workarounds

+sure the code is placed so that there's at most one forward reference in the
+addl.

+C TODO
+C  * Check if 'jmp N(%esp)' is well-predicted enough to allow us to combine the
+C    4 large loops into one; we could use it for the outer loop branch.
+C  * Optimise code outside of inner loops.
+C  * Write combined addmul_1 feed-in a wind-down code, and use when iterating
+C    outer each loop.  ("Overlapping software pipelining")
+C  * Perhaps use caller-saves regs for inlined mul_1, allowing us to postpone
+C    all pushes.
+C  * Perhaps write special code for n < M, for some small M.
+C  * Replace inlined addmul_1 with smaller code from aorsmul_1.asm, or perhaps
+C    with even less pipelined code.
+C  * We run the outer loop until we have a 2-limb by 1-limb addmul_1 left.
+C    Consider breaking out earlier, saving high the cost of short loops.

+C void mpn_copyi (mp_ptr dst, mp_srcptr src, mp_size_t size);
+C
+C Copy src,size to dst,size, working from low to high addresses.
+C
+C The code here is very generic and can be expected to be reasonable on all
+C the x86 family.
+C
+C P6 -  An MMX based copy was tried, but was found to be slower than a rep
+C       movs in all cases.  The fastest MMX found was 0.8 cycles/limb (when
+C       fully aligned).  A rep movs seems to have a startup time of about 15
+C       cycles, but doing something special for small sizes could lead to a
+C       branch misprediction that would destroy any saving.  For now a plain
+C       rep movs seems ok.
+C
+C K62 - We used to have a big chunk of code doing an MMX copy at 0.56 c/l if
+C       aligned or a 1.0 rep movs if not.  But that seemed excessive since
+C       it only got an advantage half the time, and even then only showed it
+C       above 50 limbs or so.

+C                          mp_limb_t carry);
+C
+C Divide src,size by divisor and store the quotient in dst+xsize,size.
+C Extend the division to fractional quotient limbs in dst,xsize.  Return the
+C remainder.  Either or both xsize and size can be 0.
+C
+C mpn_divrem_1c takes a carry parameter which is an initial high limb,
+C effectively one extra limb at the top of src,size.  Must have
+C carry<divisor.
+C
+C
+C Essentially the code is the same as the division based part of
+C mpn/generic/divrem_1.c, but has the advantage that we get the desired divl
+C instruction even when gcc is not being used (when longlong.h only has the
+C rather slow generic C udiv_qrnnd().
+C
+C A test is done to see if the high limb is less than the divisor, and if so
+C one less div is done.  A div is between 20 and 40 cycles on the various
+C x86s, so assuming high<divisor about half the time, then this test saves
+C half that amount.  The branch misprediction penalty on each chip is less
+C than half a div.
+C
+C
+C Notes for P5:
+C
+C It might be thought that moving the load down to pair with the store would
+C save 1 cycle, but that doesn't seem to happen in practice, and in any case
+C would be a mere 2.2% saving, so it's hardly worth bothering about.
+C
+C A mul-by-inverse might be a possibility for P5, as done in
+C mpn/x86/pentium/mod_1.asm.  The number of auxiliary instructions required
+C is a hinderance, but there could be a 10-15% speedup available.
+C
+C
+C Notes for K6:
+C
+C K6 has its own version of this code, using loop and paying attention to
+C cache line boundary crossings.  The target 20 c/l can be had with the
+C decl+jnz of the present code by pairing up the load and store in the
+C loops.  But it's considered easier not to introduce complexity just for
+C that, but instead let k6 have its own code.

+dnl  with the offset in %al.  %al is used since the movb instruction is 2
+dnl  bytes where %eax would be 4.

+dnl  instruction is assumed to be so slow it is useless.  Instead a teble is
+dnl  used.
+dnl
+dnl  The loop benefits from OoO, in-order CPUs might want a different loop.
+dnl  The ebx and ecx registers could be combined if the assigment of ecx were
+dnl  postponed until ebx died, but that would at least hurt in-order CPUs.

+			AMD K6 MPN SUBROUTINES
+
+
+
+This directory contains code optimized for AMD K6 CPUs, meaning K6, K6-2 and
+K6-3.
+
+The mmx subdirectory has MMX code suiting plain K6, the k62mmx subdirectory
+has MMX code suiting K6-2 and K6-3.  All chips in the K6 family have MMX,
+the separate directories are just so that ./configure can omit them if the
+assembler doesn't support MMX.
+
+
+
+
+STATUS
+
+Times for the loops, with all code and data in L1 cache, are as follows.
+
+                                 cycles/limb
+
+	mpn_add_n/sub_n            3.25 normal, 2.75 in-place
+
+	mpn_mul_1                  6.25
+	mpn_add/submul_1           7.65-8.4  (varying with data values)
+
+	mpn_mul_basecase           9.25 cycles/crossproduct (approx)
+	mpn_sqr_basecase           4.7  cycles/crossproduct (approx)
+                                   or 9.2 cycles/triangleproduct (approx)
+
+	mpn_l/rshift               3.0
+
+	mpn_divrem_1              20.0
+	mpn_mod_1                 20.0
+	mpn_divexact_by3          11.0
+
+	mpn_copyi                  1.0
+	mpn_copyd                  1.0
+
+
+K6-2 and K6-3 have dual-issue MMX and get the following improvements.
+
+	mpn_l/rshift               1.75
+
+
+Prefetching of sources hasn't yet given any joy.  With the 3DNow "prefetch"
+instruction, code seems to run slower, and with just "mov" loads it doesn't
+seem faster.  Results so far are inconsistent.  The K6 does a hardware
+prefetch of the second cache line in a sector, so the penalty for not
+prefetching in software is reduced.
+
+
+
+
+NOTES
+
+All K6 family chips have MMX, but only K6-2 and K6-3 have 3DNow.
+
+Plain K6 executes MMX instructions only in the X pipe, but K6-2 and K6-3 can
+execute them in both X and Y (and in both together).
+
+Branch misprediction penalty is 1 to 4 cycles (Optimization Manual
+chapter 6 table 12).
+
+Write-allocate L1 data cache means prefetching of destinations is unnecessary.
+Store queue is 7 entries of 64 bits each.
+
+Floating point multiplications can be done in parallel with integer
+multiplications, but there doesn't seem to be any way to make use of this.
+
+
+
+OPTIMIZATIONS
+
+Unrolled loops are used to reduce looping overhead.  The unrolling is
+configurable up to 32 limbs/loop for most routines, up to 64 for some.
+
+Sometimes computed jumps into the unrolling are used to handle sizes not a
+multiple of the unrolling.  An attractive feature of this is that times
+smoothly increase with operand size, but an indirect jump is about 6 cycles
+and the setups about another 6, so it depends on how much the unrolled code
+is faster than a simple loop as to whether a computed jump ought to be used.
+
+Position independent code is implemented using a call to get eip for
+computed jumps and a ret is always done, rather than an addl $4,%esp or a
+popl, so the CPU return address branch prediction stack stays synchronised
+with the actual stack in memory.  Such a call however still costs 4 to 7
+cycles.
+
+Branch prediction, in absence of any history, will guess forward jumps are
+not taken and backward jumps are taken.  Where possible it's arranged that
+the less likely or less important case is under a taken forward jump.
+
+
+
+MMX
+
+Putting emms or femms as late as possible in a routine seems to be fastest.
+Perhaps an emms or femms stalls until all outstanding MMX instructions have
+completed, so putting it later gives them a chance to complete on their own,
+in parallel with other operations (like register popping).
+
+The Optimization Manual chapter 5 recommends using a femms on K6-2 and K6-3
+at the start of a routine, in case it's been preceded by x87 floating point
+operations.  This isn't done because in gmp programs it's expected that x87
+floating point won't be much used and that chances are an mpn routine won't
+have been preceded by any x87 code.
+
+
+
+CODING
+
+Instructions in general code are shown paired if they can decode and execute
+together, meaning two short decode instructions with the second not
+depending on the first, only the first using the shifter, no more than one
+load, and no more than one store.
+
+K6 does some out of order execution so the pairings aren't essential, they
+just show what slots might be available.  When decoding is the limiting
+factor things can be scheduled that might not execute until later.
+
+
+
+NOTES
+
+Code alignment
+
+- if an opcode/modrm or 0Fh/opcode/modrm crosses a cache line boundary,
+  short decode is inhibited.  The cross.pl script detects this.
+
+- loops and branch targets should be aligned to 16 bytes, or ensure at least
+  2 instructions before a 32 byte boundary.  This makes use of the 16 byte
+  cache in the BTB.
+
+Addressing modes
+
+- (%esi) degrades decoding from short to vector.  0(%esi) doesn't have this
+  problem, and can be used as an equivalent, or easier is just to use a
+  different register, like %ebx.
+
+- K6 and pre-CXT core K6-2 have the following problem.  (K6-2 CXT and K6-3
+  have it fixed, these being cpuid function 1 signatures 0x588 to 0x58F).
+
+  If more than 3 bytes are needed to determine instruction length then
+  decoding degrades from direct to long, or from long to vector.  This
+  happens with forms like "0F opcode mod/rm" with mod/rm=00-xxx-100 since
+  with mod=00 the sib determines whether there's a displacement.
+
+  This affects all MMX and 3DNow instructions, and others with an 0F prefix,
+  like movzbl.  The modes affected are anything with an index and no
+  displacement, or an index but no base, and this includes (%esp) which is
+  really (,%esp,1).
+
+  The cross.pl script detects problem cases.  The workaround is to always
+  use a displacement, and to do this with Zdisp if it's zero so the
+  assembler doesn't discard it.
+
+  See Optimization Manual rev D page 67 and 3DNow Porting Guide rev B pages
+  13-14 and 36-37.
+
+Calls
+
+- indirect jumps and calls are not branch predicted, they measure about 6
+  cycles.
+
+Various
+
+- adcl      2 cycles of decode, maybe 2 cycles executing in the X pipe
+- bsf       12-27 cycles
+- emms      5 cycles
+- femms     3 cycles
+- jecxz     2 cycles taken, 13 not taken (optimization manual says 7 not taken)
+- divl      20 cycles back-to-back
+- imull     2 decode, 3 execute
+- mull      2 decode, 3 execute (optimization manual decoding sample)
+- prefetch  2 cycles
+- rcll/rcrl implicit by one bit: 2 cycles
+            immediate or %cl count: 11 + 2 per bit for dword
+                                    13 + 4 per bit for byte
+- setCC	    2 cycles
+- xchgl	%eax,reg  1.5 cycles, back-to-back (strange)
+        reg,reg   2 cycles, back-to-back

+C
+C The jadcl0()s in the unrolled loop makes the speed data dependent.  Small
+C multipliers (most significant few bits clear) result in few carry bits and
+C speeds up to 7.65 cycles/limb are attained.  Large multipliers (most
+C significant few bits set) make the carry bits 50/50 and lead to something
+C more like 8.4 c/l.  With adcl's both of these would be 9.3 c/l.
+C
+C It's important that the gains for jadcl0 on small multipliers don't come
+C at the cost of slowing down other data.  Tests on uniformly distributed
+C random data, designed to confound branch prediction, show about a 7%
+C speed-up using jadcl0 over adcl (8.93 versus 9.57 cycles/limb, with all
+C overheads included).
+C
+C In the simple loop, jadcl0() measures slower than adcl (11.9-14.7 versus
+C 11.0 cycles/limb), and hence isn't used.
+C
+C In the simple loop, note that running ecx from negative to zero and using
+C it as an index in the two movs wouldn't help.  It would save one
+C instruction (2*addl+loop becoming incl+jnz), but there's nothing unpaired
+C that would be collapsed by this.
+C
+C Attempts at a simpler main loop, with less unrolling, haven't yielded much
+C success, generally running over 9 c/l.
+C
+C
+C jadcl0
+C ------
+C
+C jadcl0() being faster than adcl $0 seems to be an artifact of two things,
+C firstly the instruction decoding and secondly the fact that there's a
+C carry bit for the jadcl0 only on average about 1/4 of the time.
+C
+C The code in the unrolled loop decodes something like the following.
+C
+C                                         decode cycles
+C		mull	%ebp                    2
+C		M4_inst	%esi, disp(%edi)        1
+C		adcl	%eax, %ecx              2
+C		movl	%edx, %esi            \ 1
+C		jnc	1f                    /
+C		incl	%esi                  \ 1
+C	1:	movl	disp(%ebx), %eax      /
+C                                              ---
+C                                               7
+C
+C In a back-to-back style test this measures 7 with the jnc not taken, or 8
+C with it taken (both when correctly predicted).  This is opposite to the
+C measurements showing small multipliers running faster than large ones.
+C Don't really know why.
+C
+C It's not clear how much branch misprediction might be costing.  The K6
+C doco says it will be 1 to 4 cycles, but presumably it's near the low end
+C of that range to get the measured results.
+C
+C
+C In the code the two carries are more or less the preceding mul product and
+C the calculation is roughly
+C
+C	x*y + u*b+v
+C
+C where b=2^32 is the size of a limb, x*y is the two carry limbs, and u and
+C v are the two limbs it's added to (being the low of the next mul, and a
+C limb from the destination).
+C
+C To get a carry requires x*y+u*b+v >= b^2, which is u*b+v >= b^2-x*y, and
+C there are b^2-(b^2-x*y) = x*y many such values, giving a probability of
+C x*y/b^2.  If x, y, u and v are random and uniformly distributed between 0
+C and b-1, then the total probability can be summed over x and y,
+C
+C	 1    b-1 b-1 x*y    1    b*(b-1)   b*(b-1)
+C	--- * sum sum --- = --- * ------- * ------- = 1/4
+C       b^2   x=0 y=1 b^2   b^4      2         2
+C
+C Actually it's a very tiny bit less than 1/4 of course.  If y is fixed,
+C then the probability is 1/2*y/b thus varying linearly between 0 and 1/2.

+C The unrolled loop uses a "two carry limbs" scheme.  At the top of the loop
+C the carries are ecx=lo, esi=hi, then they swap for each limb processed.
+C For the computed jump an odd size means they start one way around, an even
+C size the other.
+C
+C VAR_JUMP holds the computed jump temporarily because there's not enough
+C registers at the point of doing the mul for the initial two carry limbs.
+C
+C The add/adc for the initial carry in %esi is necessary only for the
+C mpn_addmul/submul_1c entry points.  Duplicating the startup code to
+C eliminate this for the plain mpn_add/submul_1 doesn't seem like a good
+C idea.

+#
+# Produce an annotated disassembly of the given object files, indicating
+# certain code alignment and addressing mode problems afflicting K6 chips.
+# "ZZ" is used on all annotations, so this can be searched for.
+#
+# With no arguments, all .o files corresponding to .asm files are processed.
+# This is good in the mpn object directory of a k6*-*-* build.
+#
+# Code alignments of 8 bytes or more are handled.  When 32 is used, cache
+# line boundaries will fall in at offsets 0x20,0x40,etc and problems are
+# flagged at those locations.  When 16 is used, the line boundaries can also
+# fall at offsets 0x10,0x30,0x50,etc, depending where the file is loaded, so
+# problems are identified there too.  Likewise when 8 byte alignment is used
+# problems are flagged additionally at 0x08,0x18,0x28,etc.
+#
+# Usually 32 byte alignment is used for k6 routines, but less is certainly
+# possible if through good luck, or a little tweaking, cache line crossing
+# problems can be avoided at the extra locations.
+#
+# Bugs:
+#
+# Instructions without mod/rm bytes or which are already vector decoded are

+#
+# There's no messages for using the vector decoded addressing mode (%esi),

+C
+C The code here is basically the same as mpn/x86/divrem_1.asm, but uses loop
+C instead of decl+jnz, since it comes out 2 cycles/limb faster.
+C
+C A test is done to see if the high limb is less than the divisor, and if so
+C one less div is done.  A div is 20 cycles, so assuming high<divisor about
+C half the time, then this test saves half that amount.  The branch
+C misprediction penalty is less than that.
+C
+C Back-to-back div instructions run at 20 cycles, the same as the loop here,
+C so it seems there's nothing to gain by rearranging the loop.  Pairing the
+C mov and loop instructions was found to gain nothing.
+C
+C Enhancements:
+C
+C The low-latency K6 multiply might be thought to suit a mul-by-inverse, but
+C that algorithm has been found to suffer from the relatively poor carry
+C handling on K6 and too many auxiliary instructions.  The fractional part

+C K6-2: 1.0 cycles/limb
+
+
+C void mpn_copyd (mp_ptr dst, mp_srcptr src, mp_size_t size);
+C
+C The loop here is no faster than a rep movsl at 1.0 c/l, but it avoids a 30
+C cycle startup time, which amounts for instance to a 2x speedup at 15
+C limbs.
+C
+C If dst is 4mod8 the loop would be 1.17 c/l, but that's avoided by
+C processing one limb separately to make it aligned.  This and a final odd
+C limb are handled in a branch-free fashion, ending up re-copying if the
+C special case isn't needed.
+C
+C Alternatives:
+C
+C There used to be a big unrolled version of this, running at 0.56 c/l if
+C the destination was aligned, but that seemed rather excessive for the
+C relative importance of copyd.
+C
+C If the destination alignment is ignored and just left to run at 1.17 c/l
+C some code size and a fixed few cycles can be saved.  Considering how few
+C uses copyd finds perhaps that should be favoured.  The current code has
+C the attraction of being no slower than a basic rep movsl though.

+C
+C Calculate xp,xsize multiplied by yp,ysize, storing the result in

+C
+C This routine is essentially the same as mpn/generic/mul_basecase.c, but
+C it's faster because it does most of the mpn_addmul_1() entry code only
+C once.  The saving is about 10-20% on typical sizes coming from the
+C Karatsuba multiply code.
+C
+C Enhancements:
+C
+C The mul_1 loop is about 8.5 c/l, which is slower than mpn_mul_1 at 6.25
+C c/l.  Could call mpn_mul_1 when ysize is big enough to make it worthwhile.
+C
+C The main unrolled addmul loop could be shared by mpn_addmul_1, using some
+C extra stack setups and maybe 2 or 3 wasted cycles at the end.  Code saving

+C The unrolled inner loop is the same as in aorsmul_1.asm, see that code for
+C some comments.
+C
+C VAR_COUNTER is for the inner loop, running from VAR_COUNTER_INIT down to
+C 0, inclusive.
+C
+C VAR_JMP is the computed jump into the unrolled loop.
+C
+C PARAM_XP and PARAM_WP get offset appropriately for where the unrolled loop
+C is entered.
+C
+C VAR_XP_LOW is the least significant limb of xp, which is needed at the
+C start of the unrolled loop.  This can't just be fetched through the xp
+C pointer because of the offset applied to it.
+C
+C PARAM_YSIZE is the outer loop counter, going from -(ysize-1) up to -1,
+C inclusive.
+C
+C PARAM_YP is offset appropriately so that the PARAM_YSIZE counter can be
+C added to give the location of the next limb of yp, which is the multiplier
+C in the unrolled loop.
+C
+C PARAM_WP is similarly offset so that the PARAM_YSIZE counter can be added
+C to give the starting point in the destination for each unrolled loop (this
+C point is one limb upwards for each limb of yp processed).
+C
+C Having PARAM_YSIZE count negative to zero means it's not necessary to
+C store new values of PARAM_YP and PARAM_WP on each loop.  Those values on
+C the stack remain constant and on each loop an leal adjusts them with the
+C PARAM_YSIZE counter value.

+C clearly apply only to those sizes; mid sizes like 10x10 only need part of
+C the unrolled addmul; and big sizes like 35x35 that do need all of it will
+C at least be getting value for money, because 35x35 spends something like
+C 5780 cycles here.
+C
+C Different values of UNROLL_COUNT give slightly different speeds, between
+C 9.0 and 9.2 c/tri-prod measured on the difference between 17 and 33 limbs.
+C This isn't a big difference, but it's presumably some alignment effect
+C which if understood could give a simple speedup.

+
+
+NOTES
+
+cmov, MMX, 3DNow and some extensions to MMX and 3DNow are available.
+
+Write-allocate L1 data cache means prefetching of destinations is unnecessary.
+
+Floating point multiplications can be done in parallel with integer
+multiplications, but there doesn't seem to be any way to make use of this.
+
+Unsigned "mul"s can be issued every 3 cycles.  This suggests 3 is a limit on
+the speed of the multiplication routines.  The documentation shows mul
+executing in IEU0 (or maybe in IEU0 and IEU1 together), so it might be that,
+to get near 3 cycles code has to be arranged so that nothing else is issued
+to IEU0.  A busy IEU0 could explain why some code takes 4 cycles and other
+apparently equivalent code takes 5.
+
+
+
+OPTIMIZATIONS
+
+Unrolled loops are used to reduce looping overhead.  The unrolling is
+configurable up to 32 limbs/loop for most routines and up to 64 for some.
+The K7 has 64k L1 code cache so quite big unrolling is allowable.
+
+Computed jumps into the unrolling are used to handle sizes not a multiple of
+the unrolling.  An attractive feature of this is that times increase
+smoothly with operand size, but it may be that some routines should just
+have simple loops to finish up, especially when PIC adds between 2 and 16
+cycles to get %eip.
+
+Position independent code is implemented using a call to get %eip for the
+computed jumps and a ret is always done, rather than an addl $4,%esp or a
+popl, so the CPU return address branch prediction stack stays synchronised
+with the actual stack in memory.
+
+Branch prediction, in absence of any history, will guess forward jumps are
+not taken and backward jumps are taken.  Where possible it's arranged that
+the less likely or less important case is under a taken forward jump.
+
+
+
+CODING
+
+Instructions in general code have been shown grouped if they can execute
+together, which means up to three direct-path instructions which have no
+successive dependencies.  K7 always decodes three and has out-of-order
+execution, but the groupings show what slots might be available and what
+dependency chains exist.
+
+When there's vector-path instructions an effort is made to get triplets of
+direct-path instructions in between them, even if there's dependencies,
+since this maximizes decoding throughput and might save a cycle or two if
+decoding is the limiting factor.

+C This is an attempt at an addlsh1_n for x86-32, not relying on sse2 insns.
+C The innerloop is 2*3-way unrolled, which is best we can do with the available
+C registers.  It seems tricky to use the same structure for rsblsh1_n, since we
+C cannot feed carry between operations there.

+C This is a basic addlsh1_n for k7, atom, and perhaps some other x86-32
+C processors.  It uses 2*3-way unrolling, for good reasons.  Unfortunately,
+C that means we need an initial magic multiply.
+C
+C It is not clear how to do sublsh1_n or rsblsh1_n using the same pattern.  We
+C cannot do rsblsh1_n since we feed carry from the shift blocks to the
+C add/subtract blocks, which is right for addition but reversed for
+C subtraction.  We could perhaps do sublsh1_n, with some extra move insns,
+C without losing any time, since we're not issue limited but carry recurrency
+C latency.
+C
+C Breaking carry recurrency might be a good idea.  We would then need separate
+C registers for the shift carry and add/subtract carry, which in turn would
+C force us to 2*2-way unrolling.

+C
+C The loop form below is necessary for the claimed speed.  It needs to be
+C aligned to a 16 byte boundary and only 16 bytes long.  Maybe that's so it
+C fits in a BTB entry.  The adjustments to %eax and %edx avoid offsets on
+C the movq's and achieve the necessary size.
+C
+C If both src and dst are 4mod8, the loop runs at 1.5 c/l.  So long as one
+C of the two is 0mod8, it runs at 1.0 c/l.  On that basis dst is checked
+C (offset by the size, as per the loop addressing) and one high limb
+C processed separately to get alignment.
+C
+C The padding for the nails case is unattractive, but shouldn't cost any
+C cycles.  Explicit .byte's guarantee the desired instructions, at a point
+C where we're probably stalled waiting for loads anyway.
+C
+C Enhancements:
+C
+C The combination load/pxor/store might be able to be unrolled to approach
+C 0.5 c/l if desired.

+C This code at 0.75 or 1.0 c/l is always faster than a plain rep movsl at
+C 1.33 c/l.
+C
+C The K7 can do a 64-bit load and 64-bit store in one cycle (optimization
+C guile 22007 appendix B), so 0.5 c/l should be possible, however nothing
+C under 0.7 c/l is known.  Apparently only two 32-bit stores can be done in
+C one cycle, so perhaps some scheduling is needed to ensure it's a
+C load+store in each cycle, not store+store.
+C
+C If both source and destination are unaligned then one limb is processed at
+C the start to make them aligned and so get 0.75 c/l, whereas if they'd been
+C used unaligned it would be 1.5 c/l.

+C
+C Algorithm:
+C
+C The method and nomenclature follow part 8 of "Division by Invariant
+C Integers using Multiplication" by Granlund and Montgomery, reference in
+C gmp.texi.
+C
+C The "and"s shown in the paper are done here with "cmov"s.  "m" is written
+C for m', and "d" for d_norm, which won't cause any confusion since it's
+C only the normalized divisor that's of any use in the code.  "b" is written
+C for 2^N, the size of a limb, N being 32 here.
+C
+C The step "sdword dr = n - 2^N*d + (2^N-1-q1) * d" is instead done as
+C "n-(q1+1)*d"; this rearrangement gives the same two-limb answer.  If
+C q1==0xFFFFFFFF, then q1+1 would overflow.  We branch to a special case
+C "q1_ff" if this occurs.  Since the true quotient is either q1 or q1+1 then
+C if q1==0xFFFFFFFF that must be the right value.
+C
+C For the last and second last steps q1==0xFFFFFFFF is instead handled by an
+C sbbl to go back to 0xFFFFFFFF if an overflow occurs when adding 1.  This
+C then goes through as normal, and finding no addback required.  sbbl costs
+C an extra cycle over what the main loop code does, but it keeps code size
+C and complexity down.
+C
+C Notes:
+C
+C mpn_divrem_1 and mpn_preinv_divrem_1 avoid one division if the src high
+C limb is less than the divisor.  mpn_divrem_1c doesn't check for a zero
+C carry, since in normal circumstances that will be a very rare event.
+C
+C The test for skipping a division is branch free (once size>=1 is tested).
+C The store to the destination high limb is 0 when a divide is skipped, or
+C if it's not skipped then a copy of the src high limb is used.  The latter
+C is in case src==dst.
+C
+C There's a small bias towards expecting xsize==0, by having code for
+C xsize==0 in a straight line and xsize!=0 under forward jumps.
+C
+C Alternatives:
+C
+C If the divisor is normalized (high bit set) then a division step can
+C always be skipped, since the high destination limb is always 0 or 1 in
+C that case.  It doesn't seem worth checking for this though, since it
+C probably occurs infrequently, in particular note that big_base for a
+C decimal mpn_get_str is not normalized in a 32-bit limb.
+
+
+dnl  MUL_THRESHOLD is the value of xsize+size at which the multiply by
+dnl  inverse method is used, rather than plain "divl"s.  Minimum value 1.
+dnl
+dnl  The inverse takes about 50 cycles to calculate, but after that the
+dnl  multiply is 17 c/l versus division at 42 c/l.
+dnl
+dnl  At 3 limbs the mul is a touch faster than div on the integer part, and
+dnl  even more so on the fractional part.

+C
+C The multiply by inverse loop is 17 cycles, and relies on some out-of-order
+C execution.  The instruction scheduling is important, with various
+C apparently equivalent forms running 1 to 5 cycles slower.
+C
+C A lower bound for the time would seem to be 16 cycles, based on the
+C following successive dependencies.
+C
+C		      cycles
+C		n2+n1	1
+C		mul	6
+C		q1+1	1
+C		mul	6
+C		sub	1
+C		addback	1
+C		       ---
+C		       16
+C
+C This chain is what the loop has already, but 16 cycles isn't achieved.
+C K7 has enough decode, and probably enough execute (depending maybe on what
+C a mul actually consumes), but nothing running under 17 has been found.
+C
+C In theory n2+n1 could be done in the sub and addback stages (by
+C calculating both n2 and n2+n1 there), but lack of registers makes this an
+C unlikely proposition.
+C
+C The jz in the loop keeps the q1+1 stage to 1 cycle.  Handling an overflow
+C from q1+1 with an "sbbl $0, %ebx" would add a cycle to the dependent
+C chain, and nothing better than 18 cycles has been found when using it.
+C The jump is taken only when q1 is 0xFFFFFFFF, and on random data this will
+C be an extremely rare event.
+C
+C Branch mispredictions will hit random occurrences of q1==0xFFFFFFFF, but
+C if some special data is coming out with this always, the q1_ff special
+C case actually runs at 15 c/l.  0x2FFF...FFFD divided by 3 is a good way to
+C induce the q1_ff case, for speed measurements or testing.  Note that
+C 0xFFF...FFF divided by 1 or 2 doesn't induce it.
+C
+C The instruction groupings and empty comments show the cycles for a naive
+C in-order view of the code (conveniently ignoring the load latency on
+C VAR_INVERSE).  This shows some of where the time is going, but is nonsense
+C to the extent that out-of-order execution rearranges it.  In this case
+C there's 19 cycles shown, but it executes at 17.

+C
+C Being the fractional part, the "source" limbs are all zero, meaning
+C n10=0, n1=0, and hence nadj=0, leading to many instructions eliminated.
+C
+C The loop runs at 15 cycles.  The dependent chain is the same as the
+C general case above, but without the n2+n1 stage (due to n1==0), so 15
+C would seem to be the lower bound.
+C
+C A not entirely obvious simplification is that q1+1 never overflows a limb,
+C and so there's no need for the sbbl $0 or jz q1_ff from the general case.
+C q1 is the high word of m*n2+b*n2 and the following shows q1<=b-2 always.
+C rnd() means rounding down to a multiple of d.
+C
+C	m*n2 + b*n2 <= m*(d-1) + b*(d-1)
+C		     = m*d + b*d - m - b
+C		     = floor((b(b-d)-1)/d)*d + b*d - m - b
+C		     = rnd(b(b-d)-1) + b*d - m - b
+C		     = rnd(b(b-d)-1 + b*d) - m - b
+C		     = rnd(b*b-1) - m - b
+C		     <= (b-2)*b
+C
+C Unchanged from the general case is that the final quotient limb q can be
+C either q1 or q1+1, and the q1+1 case occurs often.  This can be seen from
+C equation 8.4 of the paper which simplifies as follows when n1==0 and
+C n0==0.
+C
+C	n-q1*d = (n2*k+q0*d)/b <= d + (d*d-2d)/b
+C
+C As before, the instruction groupings and empty comments show a naive
+C in-order view of the code, which is made a nonsense by out of order
+C execution.  There's 17 cycles shown, but it executes at 15.
+C
+C Rotating the store q and remainder->n2 instructions up to the top of the
+C loop gets the run time down from 16 to 15.

+C
+C This code uses 64-bit MMX operations, which makes it possible to handle
+C two limbs at a time, for a theoretical 1.0 cycles/limb.  Plain integer
+C code, on the other hand, suffers from shrd being a vector path decode and

+C The unrolled loop is the same as in mpn_addmul_1(), see that code for some
+C comments.
+C
+C VAR_ADJUST is the negative of how many limbs the leals in the inner loop
+C increment xp and wp.  This is used to adjust back xp and wp, and rshifted
+C to given an initial VAR_COUNTER at the top of the outer loop.
+C
+C VAR_COUNTER is for the unrolled loop, running from VAR_ADJUST/UNROLL_COUNT
+C up to -1, inclusive.
+C
+C VAR_JMP is the computed jump into the unrolled loop.
+C
+C VAR_XP_LOW is the least significant limb of xp, which is needed at the
+C start of the unrolled loop.
+C
+C PARAM_YSIZE is the outer loop counter, going from -(ysize-1) up to -1,
+C inclusive.
+C
+C PARAM_YP is offset appropriately so that the PARAM_YSIZE counter can be
+C added to give the location of the next limb of yp, which is the multiplier
+C in the unrolled loop.
+C
+C The trick with VAR_ADJUST means it's only necessary to do one fetch in the
+C outer loop to take care of xp, wp and the inner loop counter.

+C This is an attempt at a sublsh1_n for x86-32, not relying on sse2 insns.  The
+C innerloop is 2*3-way unrolled, which is best we can do with the available
+C registers.  It seems tricky to use the same structure for rsblsh1_n, since we
+C cannot feed carry between operations there.

+C This is a basic sublsh1_n for k7, atom, and perhaps some other x86-32
+C processors.  It uses 2*4-way unrolling, for good reasons.
+C
+C Breaking carry recurrency might be a good idea.  We would then need separate
+C registers for the shift carry and add/subtract carry, which in turn would
+C force us to 2*2-way unrolling.

+C This was written in a haste since the Pentium optimized code that was used
+C for all x86 machines was slow for the Pentium II.  This code would benefit
+C from some cleanup.
+C
+C To shave off some percentage of the run-time, one should make 4 variants
+C of the Louter loop, for the four different outcomes of un mod 4.  That
+C would avoid Loop0 altogether.  Code expansion would be > 4-fold for that
+C part of the function, but since it is not very large, that would be
+C acceptable.
+C
+C The mul loop (at L(oopM)) might need some tweaking.  It's current speed is

+                      INTEL P6 MPN SUBROUTINES
+
+
+
+This directory contains code optimized for Intel P6 class CPUs, meaning
+PentiumPro, Pentium II and Pentium III.  The mmx and p3mmx subdirectories
+have routines using MMX instructions.
+
+
+
+STATUS
+
+Times for the loops, with all code and data in L1 cache, are as follows.
+Some of these might be able to be improved.
+
+                               cycles/limb
+
+	mpn_add_n/sub_n           3.7
+
+	mpn_copyi                 0.75
+	mpn_copyd                 1.75 (or 0.75 if no overlap)
+
+	mpn_divrem_1             39.0
+	mpn_mod_1                21.5
+	mpn_divexact_by3          8.5
+
+	mpn_mul_1                 5.5
+	mpn_addmul/submul_1       6.35
+
+	mpn_l/rshift              2.5
+
+	mpn_mul_basecase          8.2 cycles/crossproduct (approx)
+	mpn_sqr_basecase          4.0 cycles/crossproduct (approx)
+				  or 7.75 cycles/triangleproduct (approx)
+
+Pentium II and III have MMX and get the following improvements.
+
+	mpn_divrem_1             25.0 integer part, 17.5 fractional part
+
+	mpn_l/rshift              1.75
+
+
+
+
+NOTES
+
+Write-allocate L1 data cache means prefetching of destinations is unnecessary.
+
+Mispredicted branches have a penalty of between 9 and 15 cycles, and even up
+to 26 cycles depending how far speculative execution has gone.  The 9 cycle
+minimum penalty comes from the issue pipeline being 9 stages.
+
+A copy with rep movs seems to copy 16 bytes at a time, since speeds for 4,
+5, 6 or 7 limb operations are all the same.  The 0.75 cycles/limb would be 3
+cycles per 16 byte block.
+
+
+
+
+CODING
+
+Instructions in general code have been shown grouped if they can execute
+together, which means up to three instructions with no successive
+dependencies, and with only the first being a multiple micro-op.
+
+P6 has out-of-order execution, so the groupings are really only showing
+dependent paths where some shuffling might allow some latencies to be
+hidden.

+
+
+C void mpn_copyd (mp_ptr dst, mp_srcptr src, mp_size_t size);
+C
+C An explicit loop is used because a decrementing rep movsl is a bit slow at
+C 2.4 c/l.  That rep movsl also has about a 40 cycle startup time, and the
+C code here stands a chance of being faster if the branches predict well.
+C
+C The slightly strange loop form seems necessary for the claimed speed.
+C Maybe load/store ordering affects it.
+C
+C The source and destination are checked to see if they're actually
+C overlapping, since it might be possible to use an incrementing rep movsl
+C at 0.75 c/l.  (It doesn't suffer the bad startup time of the decrementing
+C version.)
+C
+C Enhancements:
+C
+C Top speed for an all-integer copy is probably 1.0 c/l, being one load and
+C one store each cycle.  Unrolling the loop below would approach 1.0, but
+C it'd be good to know why something like store/load/subl + store/load/jnz
+C doesn't already run at 1.0 c/l.  It looks like it should decode in 2
+C cycles, but doesn't run that way.

+dnl  MUL_THRESHOLD is the value of xsize+size at which the multiply by
+dnl  inverse method is used, rather than plain "divl"s.  Minimum value 1.
+dnl
+dnl  The different speeds of the integer and fraction parts means that using
+dnl  xsize+size isn't quite right.  The threshold wants to be a bit higher
+dnl  for the integer part and a bit lower for the fraction part.  (Or what's
+dnl  really wanted is to speed up the integer part!)
+dnl
+dnl  The threshold is set to make the integer part right.  At 4 limbs the
+dnl  div and mul are about the same there, but on the fractional part the
+dnl  mul is much faster.

+C This loop runs at about 25 cycles, which is probably sub-optimal, and
+C certainly more than the dependent chain would suggest.  A better loop, or
+C a better rough analysis of what's possible, would be welcomed.
+C
+C In the current implementation, the following successively dependent
+C micro-ops seem to exist.
+C
+C		       uops
+C		n2+n1	1   (addl)
+C		mul	5
+C		q1+1	3   (addl/adcl)
+C		mul	5
+C		sub	3   (subl/sbbl)
+C		addback	2   (cmov)
+C		       ---
+C		       19
+C
+C Lack of registers hinders explicit scheduling and it might be that the
+C normal out of order execution isn't able to hide enough under the mul
+C latencies.
+C
+C Using sarl/negl to pick out n1 for the n2+n1 stage is a touch faster than
+C cmov (and takes one uop off the dependent chain).  A sarl/andl/addl
+C combination was tried for the addback (despite the fact it would lengthen
+C the dependent chain) but found to be no faster.

+C Groups of three limbs are handled, with carry bits from 0mod3 into 1mod3
+C into 2mod3, but at that point going into a separate carries total so we
+C don't keep the carry flag live across the loop control.  Avoiding decl

+C The unrolled loop is the same as in mpn_addmul_1, see that code for some
+C comments.
+C
+C VAR_ADJUST is the negative of how many limbs the leals in the inner loop
+C increment xp and wp.  This is used to adjust xp and wp, and is rshifted to
+C given an initial VAR_COUNTER at the top of the outer loop.
+C
+C VAR_COUNTER is for the unrolled loop, running from VAR_ADJUST/UNROLL_COUNT
+C up to -1, inclusive.
+C
+C VAR_JMP is the computed jump into the unrolled loop.
+C
+C VAR_SWAP is 0 if xsize odd or 0xFFFFFFFF if xsize even, used to swap the
+C initial ebx and ecx on entry to the unrolling.
+C
+C VAR_XP_LOW is the least significant limb of xp, which is needed at the
+C start of the unrolled loop.
+C
+C PARAM_YSIZE is the outer loop counter, going from -(ysize-1) up to -1,
+C inclusive.
+C
+C PARAM_YP is offset appropriately so that the PARAM_YSIZE counter can be
+C added to give the location of the next limb of yp, which is the multiplier
+C in the unrolled loop.
+C
+C The trick with the VAR_ADJUST value means it's only necessary to do one
+C fetch in the outer loop to take care of xp, wp and the inner loop counter.

+C The code size might look a bit excessive, but not all of it is executed so

+                   INTEL PENTIUM P5 MPN SUBROUTINES
+
+
+This directory contains mpn functions optimized for Intel Pentium (P5,P54)
+processors.  The mmx subdirectory has additional code for Pentium with MMX
+(P55).
+
+

+	mpn_mod_1                 28.0
+	mpn_divexact_by3          15.0
+
+	mpn_copyi/copyd            1.0
+
+Pentium MMX gets the following improvements
+
+	mpn_l/rshift               1.75
+
+	mpn_mul_1                 12.0 normal, 7.0 for 16-bit multiplier
+
+
+mpn_add_n and mpn_sub_n run at asymptotically 2 cycles/limb.  Due to loop
+overhead and other delays (cache refill?), they run at or near 2.5
+cycles/limb.
+
+mpn_mul_1, mpn_addmul_1, mpn_submul_1 all run 1 cycle faster than they
+should.  Intel documentation says a mul instruction is 10 cycles, but it
+measures 9 and the routines using it run as 9.
+
+
+
+P55 MMX AND X87
+
+The cost of switching between MMX and x87 floating point on P55 is about 100
+cycles (fld1/por/emms for instance).  In order to avoid that the two aren't
+mixed and currently that means using MMX and not x87.
+
+MMX offers a big speedup for lshift and rshift, and a nice speedup for
+16-bit multipliers in mpn_mul_1.  If fast code using x87 is found then
+perhaps the preference for MMX will be reversed.
+
+
+
+
+P54 SHLDL
+
+mpn_lshift and mpn_rshift run at about 6 cycles/limb on P5 and P54, but the
+documentation indicates that they should take only 43/8 = 5.375 cycles/limb,
+or 5 cycles/limb asymptotically.  The P55 runs them at the expected speed.
+
+It seems that on P54 a shldl or shrdl allows pairing in one following cycle,
+but not two.  For example, back to back repetitions of the following
+
+	shldl(	%cl, %eax, %ebx)
+	xorl	%edx, %edx
+	xorl	%esi, %esi
+
+run at 5 cycles, as expected, but repetitions of the following run at 7
+cycles, whereas 6 would be expected (and is achieved on P55),
+
+	shldl(	%cl, %eax, %ebx)
+	xorl	%edx, %edx
+	xorl	%esi, %esi
+	xorl	%edi, %edi
+	xorl	%ebp, %ebp
+
+Three xorls run at 7 cycles too, so it doesn't seem to be just that pairing
+inhibited is only in the second following cycle (or something like that).
+
+Avoiding this problem would bring P54 shifts down from 6.0 c/l to 5.5 with a
+pattern of shift, 2 loads, shift, 2 stores, shift, etc.  A start has been
+made on something like that, but it's not yet complete.
+
+
+
+
+OTHER NOTES
+
+Prefetching Destinations
+
+    Pentium doesn't allocate cache lines on writes, unlike most other modern
+    processors.  Since the functions in the mpn class do array writes, we
+    have to handle allocating the destination cache lines by reading a word
+    from it in the loops, to achieve the best performance.
+
+Prefetching Sources
+
+    Prefetching of sources is pointless since there's no out-of-order loads.
+    Any load instruction blocks until the line is brought to L1, so it may
+    as well be the load that wants the data which blocks.
+
+Data Cache Bank Clashes
+
+    Pairing of memory operations requires that the two issued operations
+    refer to different cache banks (ie. different addresses modulo 32
+    bytes).  The simplest way to ensure this is to read/write two words from
+    the same object.  If we make operations on different objects, they might
+    or might not be to the same cache bank.
+
+PIC %eip Fetching
+
+    A simple call $+5 and popl can be used to get %eip, there's no need to
+    balance calls and returns since P5 doesn't have any return stack branch
+    prediction.
+
+Float Multiplies
+
+    fmul is pairable and can be issued every 2 cycles (with a 4 cycle
+    latency for data ready to use).  This is a lot better than integer mull
+    or imull at 9 cycles non-pairing.  Unfortunately the advantage is
+    quickly eaten away by needing to throw data through memory back to the
+    integer registers to adjust for fild and fist being signed, and to do
+    things like propagating carry bits.

+C
+C Destination prefetching is done to avoid repeated write-throughs on lines
+C not already in L1.
+C
+C At least one of the src or dst pointer needs to be incremented rather than
+C using indexing, so that there's somewhere to put the loop control without
+C an AGI.  Incrementing one and not two lets us keep loop overhead to 2
+C cycles.  Making it the src pointer incremented avoids an AGI on the %ecx
+C subtracts in the finishup code.
+C
+C The block of finishup code is almost as big as the main loop itself, which
+C is unfortunate, but it's faster that way than with say rep movsl, by about
+C 10 cycles for instance on P55.
+C
+C There's nothing to be gained from MMX on P55, since it can do only one
+C movq load (or store) per cycle, so the throughput would be the same as the
+C code here (and even then only if src and dst have the same alignment mod
+C 8).

+C or size>=4 when the divisor is even.  Actually on P55 size==2 for odd or
+C size==3 for even are about the same speed for both divl or mul, but the
+C former is used since it will use up less code cache.
+C
+C The P55 speeds noted above, 23 cycles odd or 28 cycles even, are as
+C expected.  On P54 in the even case the shrdl pairing nonsense (see
+C mpn/x86/pentium/README) costs 1 cycle, but it's not clear why there's a

+C
+C We're one register short of being able to do a simple 4 loads, 2 ops, 2
+C stores.  Instead %ebp is juggled a bit and nops are introduced to keep the
+C pairings as intended.  An in-place operation would free up a register, for
+C an 0.5 c/l speedup, if that's worth bothering with.
+C
+C This code seems best for P55 too.  Data alignment is a big problem for MMX

+C    cycles/limb
+C P5:   12.0   for 32-bit multiplier
+C        7.0   for 16-bit multiplier
+
+
+C mp_limb_t mpn_mul_1 (mp_ptr dst, mp_srcptr src, mp_size_t size,
+C                      mp_limb_t multiplier);
+C
+C When the multiplier is 16 bits some special case MMX code is used.  Small
+C multipliers might arise reasonably often from mpz_mul_ui etc.  If the size
+C is odd there's roughly a 5 cycle penalty, so times for say size==7 and
+C size==8 end up being quite close.  If src isn't aligned to an 8 byte
+C boundary then one limb is processed separately with roughly a 5 cycle
+C penalty, so in that case it's say size==8 and size==9 which are close.
+C
+C Alternatives:
+C
+C MMX is not believed to be of any use for 32-bit multipliers, since for
+C instance the current method would just have to be more or less duplicated
+C for the high and low halves of the multiplier, and would probably
+C therefore run at about 14 cycles, which is slower than the plain integer
+C at 12.
+C
+C Adding the high and low MMX products using integer code seems best.  An
+C attempt at using paddd and carry bit propagation with pcmpgtd didn't give
+C any joy.  Perhaps something could be done keeping the values signed and
+C thereby avoiding adjustments to make pcmpgtd into an unsigned compare, or
+C perhaps not.
+C
+C Future:
+C
+C An mpn_mul_1c entrypoint would need a double carry out of the low result
+C limb in the 16-bit code, unless it could be assumed the carry fits in 16
+C bits, possibly as carry<multiplier, this being true of a big calculation
+C done piece by piece.  But let's worry about that if/when mul_1c is
+C actually used.

+C The scheduling here is quite tricky, since so many instructions have

+C instructions are rotated to the top of the loop to find somewhere useful
+C for it.
+C
+C Trouble has been taken to avoid overlapping successive loop iterations,
+C since that would greatly increase the size of the startup and finishup
+C code.  Actually there's probably not much advantage to be had from
+C overlapping anyway, since the difficulties are mostly with pairing, not
+C with latencies as such.
+C
+C In the comments x represents the src data and m the multiplier (16

+C
+C Full speed depends on source and destination being aligned.  Unaligned mmx

+C There seems no way to pair up the two lone instructions in the main loop.
+C
+C The special case for size==1 saves about 20 cycles (non-PIC), making it
+C the same as mpn_mod_1, and in fact making modexact faster than mod_1 at
+C all sizes.
+C
+C Alternatives:
+C
+C Using mmx for the multiplies might be possible, with pmullw and pmulhw
+C having just 3 cycle latencies, but carry bit handling would probably be

+                   INTEL PENTIUM-4 MPN SUBROUTINES
+
+
+This directory contains mpn functions optimized for Intel Pentium-4.
+
+The mmx subdirectory has routines using MMX instructions, the sse2
+subdirectory has routines using SSE2 instructions.  All P4s have these, the
+separate directories are just so configure can omit that code if the
+assembler doesn't support it.

+
+
+
+The shifts ought to be able to go at 1.5 c/l, but not much effort has been
+applied to them yet.
+
+In-place operations, and all addmul, submul, mul_basecase and sqr_basecase
+calls, suffer from pipeline anomalies associated with write combining and
+movd reads and writes to the same or nearby locations.  The movq
+instructions do not trigger the same hardware problems.  Unfortunately,
+using movq and splitting/combining seems to require too many extra
+instructions to help.  Perhaps future chip steppings will be better.
+
+
+
+NOTES
+
+The Pentium-4 pipeline "Netburst", provides for quite a number of surprises.
+Many traditional x86 instructions run very slowly, requiring use of
+alterative instructions for acceptable performance.
+
+adcl and sbbl are quite slow at 8 cycles for reg->reg.  paddq of 32-bits
+within a 64-bit mmx register seems better, though the combination
+paddq/psrlq when propagating a carry is still a 4 cycle latency.
+
+incl and decl should be avoided, instead use add $1 and sub $1.  Apparently
+the carry flag is not separately renamed, so incl and decl depend on all
+previous flags-setting instructions.
+
+shll and shrl have a 4 cycle latency, or 8 times the latency of the fastest
+integer instructions (addl, subl, orl, andl, and some more).  shldl and
+shrdl seem to have 13 and 15 cycles latency, respectively.  Bizarre.
+
+movq mmx -> mmx does have 6 cycle latency, as noted in the documentation.
+pxor/por or similar combination at 2 cycles latency can be used instead.
+The movq however executes in the float unit, thereby saving MMX execution
+resources.  With the right juggling, data moves shouldn't be on a dependent
+chain.
+
+L1 is write-through, but the write-combining sounds like it does enough to
+not require explicit destination prefetching.
+
+xmm registers so far haven't found a use, but not much effort has been
+expended.  A configure test for whether the operating system knows
+fxsave/fxrestor will be needed if they're used.

+C The dependent chain is simply the paddq of x+2*y to the previous carry,
+C then psrlq to get the new carry.  That makes 4 c/l the target speed, which
+C is almost achieved for separate src/dst but when src==dst the write

+C
+C Algorithm:
+C
+C The method and nomenclature follow part 8 of "Division by Invariant
+C Integers using Multiplication" by Granlund and Montgomery, reference in
+C gmp.texi.
+C
+C "m" is written for what is m' in the paper, and "d" for d_norm, which
+C won't cause any confusion since it's only the normalized divisor that's of
+C any use in the code.  "b" is written for 2^N, the size of a limb, N being
+C 32 here.
+C
+C The step "sdword dr = n - 2^N*d + (2^N-1-q1) * d" is instead done as
+C "n-d - q1*d".  This rearrangement gives the same two-limb answer but lets
+C us have just a psubq on the dependent chain.
+C
+C For reference, the way the k7 code uses "n-(q1+1)*d" would not suit here,
+C detecting an overflow of q1+1 when q1=0xFFFFFFFF would cost too much.
+C
+C Notes:
+C
+C mpn_divrem_1 and mpn_preinv_divrem_1 avoid one division if the src high
+C limb is less than the divisor.  mpn_divrem_1c doesn't check for a zero
+C carry, since in normal circumstances that will be a very rare event.
+C
+C The test for skipping a division is branch free (once size>=1 is tested).
+C The store to the destination high limb is 0 when a divide is skipped, or
+C if it's not skipped then a copy of the src high limb is stored.  The
+C latter is in case src==dst.
+C
+C There's a small bias towards expecting xsize==0, by having code for
+C xsize==0 in a straight line and xsize!=0 under forward jumps.
+C
+C Enhancements:
+C
+C The loop measures 32 cycles, but the dependent chain would suggest it
+C could be done with 30.  Not sure where to start looking for the extras.
+C
+C Alternatives:
+C
+C If the divisor is normalized (high bit set) then a division step can
+C always be skipped, since the high destination limb is always 0 or 1 in
+C that case.  It doesn't seem worth checking for this though, since it
+C probably occurs infrequently.
+
+
+dnl  MUL_THRESHOLD is the value of xsize+size at which the multiply by
+dnl  inverse method is used, rather than plain "divl"s.  Minimum value 1.
+dnl
+dnl  The inverse takes about 80-90 cycles to calculate, but after that the
+dnl  multiply is 32 c/l versus division at about 58 c/l.
+dnl
+dnl  At 4 limbs the div is a touch faster than the mul (and of course
+dnl  simpler), so start the mul from 5 limbs.

+C  * Save around 120 bytes by remapping "m 0", "m 1", "m 2" and "m 3" registers

+C  * Make an mpn_hamdist based on this.  Alignment could either be handled by
+C    using movdqu for one operand and movdqa for the other, or by painfully
+C    shifting as we go.  Unfortunately, there seem to be no usable shift
+C    instruction, except for one that takes an immediate count.
+C  * It would probably be possible to cut a few cycles/limb using software
+C    pipelining.
+C  * There are 35 decode slots unused by the SSE2 instructions.  Loop control
+C    needs just 2 or 3 slots, leaving around 32 slots.  This allows a parallel
+C    integer based popcount.  Such a combined loop would handle 6 limbs in
+C    about 30 cycles on K8.
+C  * We could save a byte or two by using 32-bit operations on areg.
+C  * Check if using movdqa to a temp of and then register-based pand is faster.

+C P6 model 0-8,10-12		-
+C P6 model 9   (Banias)		6.8
+C P6 model 13  (Dothan)		6.9
+C P4 model 0-1 (Willamette)	?
+C P4 model 2   (Northwood)	5.87
+C P4 model 3-4 (Prescott)	6.5
+
+C This code represents a step forwards compared to the code available before
+C GMP 5.1, but it is not carefully tuned for either P6 or P4.  In fact, it is
+C not good for P6.  For P4 it saved a bit over 1 c/l for both Northwood and
+C Prescott compared to the old code.
+C
+C The arrangements made here to get a two instruction dependent chain are
+C slightly subtle.  In the loop the carry (or borrow rather) is a negative so
+C that a paddq can be used to give a low limb ready to store, and a high limb
+C ready to become the new carry after a psrlq.
+C
+C If the carry was a simple twos complement negative then the psrlq shift would
+C need to bring in 0 bits or 1 bits according to whether the high was zero or
+C non-zero, since a non-zero value would represent a negative needing sign
+C extension.  That wouldn't be particularly easy to arrange and certainly would
+C add an instruction to the dependent chain, so instead an offset is applied so
+C that the high limb will be 0xFFFFFFFF+c.  With c in the range -0xFFFFFFFF to
+C 0, the value 0xFFFFFFFF+c is in the range 0 to 0xFFFFFFFF and is therefore
+C always positive and can always have 0 bits shifted in, which is what psrlq
+C does.
+C
+C The extra 0xFFFFFFFF must be subtracted before c is used, but that can be
+C done off the dependent chain.  The total adjustment then is to add
+C 0xFFFFFFFF00000000 to offset the new carry, and subtract 0x00000000FFFFFFFF
+C to remove the offset from the current carry, for a net add of
+C 0xFFFFFFFE00000001.  In the code this is applied to the destination limb when
+C fetched.
+C
+C It's also possible to view the 0xFFFFFFFF adjustment as a ones-complement
+C negative, which is how it's undone for the return value, but that doesn't
+C seem as clear.

+C void mpn_sqr_basecase (mp_ptr dst, mp_srcptr src, mp_size_t size);
+C
+C The algorithm is basically the same as mpn/generic/sqr_basecase.c, but a
+C lot of function call overheads are avoided, especially when the size is
+C small.
+C
+C The mul1 loop is not unrolled like mul_1.asm, it doesn't seem worth the
+C code size to do so here.
+C
+C Enhancements:
+C
+C The addmul loop here is also not unrolled like aorsmul_1.asm and
+C mul_basecase.asm are.  Perhaps it should be done.  It'd add to the
+C complexity, but if it's worth doing in the other places then it should be
+C worthwhile here.
+C
+C A fully-unrolled style like other sqr_basecase.asm versions (k6, k7, p6)
+C might be worth considering.  That'd add quite a bit to the code size, but
+C only as much as is used would be dragged into L1 cache.

+
+dnl  Notes:
+dnl
+dnl  m4 isn't perfect for processing BSD style x86 assembler code, the main
+dnl  problems are,
+dnl
+dnl  1. Doing define(foo,123) and then using foo in an addressing mode like
+dnl     foo(%ebx) expands as a macro rather than a constant.  This is worked
+dnl     around by using deflit() from asm-defs.m4, instead of define().
+dnl
+dnl  2. Immediates in macro definitions need a space or `' to stop the $
+dnl     looking like a macro parameter.  For example,
+dnl
+dnl	        define(foo, `mov $ 123, %eax')
+dnl
+dnl     This is only a problem in macro definitions, not in ordinary text,
+dnl     and not in macro parameters like text passed to forloop() or ifdef().
+
+
+deflit(GMP_LIMB_BYTES, 4)
+
+
+dnl  Libtool gives -DPIC -DDLL_EXPORT to indicate a cygwin or mingw DLL.  We
+dnl  undefine PIC since we don't need to be position independent in this
+dnl  case and definitely don't want the ELF style _GLOBAL_OFFSET_TABLE_ etc.
+
+ifdef(`DLL_EXPORT',`undefine(`PIC')')
+
+
+dnl  Usage: CPUVEC_FUNCS_LIST
+dnl
+dnl  A list of the functions from gmp-impl.h x86 struct cpuvec_t, in the
+dnl  order they appear in that structure.

+dnl  Usage: call_instrument(enter|exit)
+dnl
+dnl  Call __cyg_profile_func_enter or __cyg_profile_func_exit.
+dnl
+dnl  For PIC, most routines don't require _GLOBAL_OFFSET_TABLE_ themselves
+dnl  so %ebx is just setup for these calls.  It's a bit wasteful to repeat
+dnl  the setup for the exit call having done it earlier for the enter, but
+dnl  there's nowhere very convenient to hold %ebx through the length of a
+dnl  routine, in general.
+dnl
+dnl  For PIC, because instrument_current_function will be within the current
+dnl  object file we can get it just as an offset from %eip, there's no need
+dnl  to use the GOT.
+dnl
+dnl  No attempt is made to maintain the stack alignment gcc generates with
+dnl  -mpreferred-stack-boundary.  This wouldn't be hard, but it seems highly
+dnl  unlikely the instrumenting functions would be doing anything that'd
+dnl  benefit from alignment, in particular they're unlikely to be using
+dnl  doubles or long doubles on the stack.
+dnl
+dnl  The FRAME scheme is used to conveniently account for the register saves
+dnl  before accessing the return address.  Any previous value is saved and
+dnl  restored, since plenty of code keeps a value across a "ret" in the

+dnl  Various x86 macros.
+dnl
+
+
+dnl  Usage: ALIGN_OFFSET(bytes,offset)
+dnl
+dnl  Align to `offset' away from a multiple of `bytes'.
+dnl
+dnl  This is useful for testing, for example align to something very strict
+dnl  and see what effect offsets from it have, "ALIGN_OFFSET(256,32)".
+dnl
+dnl  Generally you wouldn't execute across the padding, but it's done with
+dnl  nop's so it'll work.
+
+define(ALIGN_OFFSET,
+m4_assert_numargs(2)
+`ALIGN($1)
+forloop(`i',1,$2,`	nop
+')')
+
+
+dnl  Usage: defframe(name,offset)
+dnl
+dnl  Make a definition like the following with which to access a parameter
+dnl  or variable on the stack.
+dnl
+dnl         define(name,`FRAME+offset(%esp)')
+dnl
+dnl  Actually m4_empty_if_zero(FRAME+offset) is used, which will save one
+dnl  byte if FRAME+offset is zero, by putting (%esp) rather than 0(%esp).
+dnl  Use define(`defframe_empty_if_zero_disabled',1) if for some reason the
+dnl  zero offset is wanted.
+dnl
+dnl  The new macro also gets a check that when it's used FRAME is actually
+dnl  defined, and that the final %esp offset isn't negative, which would
+dnl  mean an attempt to access something below the current %esp.
+dnl
+dnl  deflit() is used rather than a plain define(), so the new macro won't
+dnl  delete any following parenthesized expression.  name(%edi) will come
+dnl  out say as 16(%esp)(%edi).  This isn't valid assembler and should
+dnl  provoke an error, which is better than silently giving just 16(%esp).

+
+dnl  Usage: emms_or_femms
+dnl         femms_available_p
+dnl
+dnl  femms_available_p expands to 1 or 0 according to whether the AMD 3DNow
+dnl  femms instruction is available.  emms_or_femms expands to femms if
+dnl  available, or emms if not.
+dnl
+dnl  emms_or_femms is meant for use in the K6 directory where plain K6
+dnl  (without femms) and K6-2 and K6-3 (with a slightly faster femms) are
+dnl  supported together.
+dnl

+dnl
+dnl  Generate a jnc/incl as a substitute for adcl $0,op.  Note this isn't an

+dnl
+dnl  This finds a use in K6 mpn_addmul_1, mpn_submul_1, mpn_mul_basecase and
+dnl  mpn_sqr_basecase because on K6 an adcl is slow, the branch
+dnl  misprediction penalty is small, and the multiply algorithm used leads
+dnl  to a carry bit on average only 1/4 of the time.
+dnl
+dnl  jadcl0_disabled can be set to 1 to instead generate an ordinary adcl

+
+dnl  Usage: Zdisp(inst,op,op,op)
+dnl
+dnl  Generate explicit .byte sequences if necessary to force a byte-sized
+dnl  zero displacement on an instruction.  For example,
+dnl
+dnl         Zdisp(  movl,   0,(%esi), %eax)
+dnl
+dnl  expands to
+dnl
+dnl                 .byte   139,70,0  C movl 0(%esi), %eax
+dnl
+dnl  If the displacement given isn't 0, then normal assembler code is
+dnl  generated.  For example,
+dnl
+dnl         Zdisp(  movl,   4,(%esi), %eax)
+dnl
+dnl  expands to
+dnl
+dnl                 movl    4(%esi), %eax
+dnl
+dnl  This means a single Zdisp() form can be used with an expression for the
+dnl  displacement, and .byte will be used only if necessary.  The
+dnl  displacement argument is eval()ed.
+dnl
+dnl  Because there aren't many places a 0(reg) form is wanted, Zdisp is
+dnl  implemented with a table of instructions and encodings.  A new entry is
+dnl  needed for any different operation or registers.  The table is split
+dnl  into separate macros to avoid overflowing BSD m4 macro expansion space.

+			AMD64 MPN SUBROUTINES
+
+
+This directory contains mpn functions for AMD64 chips.  It is also useful
+for 64-bit Pentiums, and "Core 2".
+
+
+		     RELEVANT OPTIMIZATION ISSUES
+
+The Opteron and Athlon64 can sustain up to 3 instructions per cycle, but in
+practice that is only possible for integer instructions.  But almost any
+three integer instructions can issue simultaneously, including any 3 ALU
+operations, including shifts.  Up to two memory operations can issue each
+cycle.
+
+Scheduling typically requires that load-use instructions are split into
+separate load and use instructions.  That requires more decode resources,
+and it is rarely a win.  Opteron/Athlon64 have deep out-of-order core.
+
+
+Optimizing for 64-bit Pentium4 is probably a waste of time, as the most
+critical instructions are very poorly implemented here.  Perhaps we could
+save a cycle or two, but the most common loops now run at between 10 and 22
+cycles, so a saved cycle isn't too exciting.
+
+
+The new spin of the venerable P6 core, the "Core 2" is much better than the
+Pentium4 for the GMP loops.  Its integer pipeline is somewhat similar to to
+the Opteron/Athlon64 pipeline, except that the GMP favourites ADC/SBB and
+MUL are slower.  Furthermore, an INC/DEC followed by ADC/SBB incur a
+pipeline stall of around 10 cycles.  The default mpn_add_n and mpn_sub_n
+code suffers badly from the stall.  The code in the core2 subdirectory uses
+the almost forgotten instruction JRCXZ for loop control, and updates the
+induction variable using LEA.

+C   1) Use indexing to save the 3 LEA
+C   2) Write reasonable feed-in code
+C   3) Be more clever about register usage
+C   4) Unroll more, handling CL negation, carry save/restore cost much now

+C  * Consider inlining mpn_add_n.
+C  * Single basecases out before the pushes.
+C  * Make lead-in code for the inner loops be more similar.

+This directory contains code for AMD bulldozer including its piledriver update.
+
+We currently make limited use of SIMD instructions, both via the MPN_PATH and
+via inclusion of x86_64/fastsse files.
+
+The bd1 cores share one SIMD/FPU pipeline for two integer units.  This probably
+means that an all-core GMP load (such as a HPC load) might run slower if there
+is significant SIMD dependency.
+
+We should perhaps allow a special 'bd1nosimd' pseudo cpu-name excluding any
+SIMD code.

+C  * We need to use .byte for vpshlb, vpperm, vphaddubq, and all popcnt if we
+C    intend to support old systems.
+
+C We use vpshlb and vpperm below, which are XOP extensions to AVX.  Some
+C systems, e.g., NetBSD, set OSXSAVE but nevertheless trigger SIGILL for AVX.
+C We fall back to the core2 code.

+
+C This mul_basecase is based on mul_1 and addmul_1, since these both run at the
+C multiply insn bandwidth, without any apparent loop branch exit pipeline
+C replays experienced on K8.  The structure is unusual: it falls into mul_1 in
+C the same way for all n, then it splits into 4 different wind-down blocks and
+C 4 separate addmul_1 loops.
+C
+C We have not tried using the same addmul_1 loops with a switch into feed-in
+C code, as we do in other basecase implementations.  Doing that could save
+C substantial code volume, but would also probably add some overhead.
+
+C TODO
+C  * Tune un < 3 code.
+C  * Fix slowdown for un=vn=3 (67->71) compared to default code.
+C  * This is 1263 bytes, compared to 1099 bytes for default code.  Consider
+C    combining addmul loops like that code.  Tolerable slowdown?
+C  * Lots of space could be saved by replacing the "switch" code by gradual
+C    jumps out from mul_1 winddown code, perhaps with no added overhead.
+C  * Are the ALIGN(16) really necessary?  They add about 25 bytes of padding.

+
+C This sqr_basecase is based on mul_1 and addmul_1, since these both run at the
+C multiply insn bandwidth, without any apparent loop branch exit pipeline
+C replays experienced on K8.  The structure is unusual: it falls into mul_1 in
+C the same way for all n, then it splits into 4 different wind-down blocks and
+C 4 separate addmul_1 loops.
+C
+C We have not tried using the same addmul_1 loops with a switch into feed-in
+C code, as we do in other basecase implementations.  Doing that could save
+C substantial code volume, but would also probably add some overhead.
+
+C TODO
+C  * Tune un < 4 code.
+C  * Perhaps implement a larger final corner (it is now 2 x 1).
+C  * Lots of space could be saved by replacing the "switch" code by gradual
+C    jumps out from mul_1 winddown code, perhaps with no added overhead.
+C  * Are the ALIGN(16) really necessary?  They add about 25 bytes of padding.

+C NOTES
+C  * It might seem natural to use the cmov insn here, but since this function
+C    is supposed to have the exact same execution pattern for cnd true and
+C    false, and since cmov's documentation is not clear about whether it
+C    actually reads both source operands and writes the register for a false
+C    condition, we cannot use it.
+C  * Two cases could be optimised: (1) cnd_add_n could use ADCSBB-from-memory
+C    to save one insn/limb, and (2) when up=rp cnd_add_n and cnd_sub_n could use
+C    ADCSBB-to-memory, again saving 1 insn/limb.
+C  * This runs optimally at decoder bandwidth on K10.  It has not been tuned
+C    for any other processor.

+C TODO
+C  * Tune.  None done so far.
+C  * Currently 2761 bytes, making it smaller would be nice.
+C  * Consider using a jumptab-based entry sequence.  One might even use a mask-
+C    less sequence, if the table is large enough to support tuneup's needs.
+C    The code would be, using non-PIC code,
+C        lea tab(%rip),%rax; jmp *(n,%rax)
+C    or,
+C        lea tab(%rip),%rax; lea (%rip),%rbx; add (n,%rax),%rbx; jmp *%rbx
+C    using PIC code.  The table entries would be Ln1,Ln2,Ln3,Lm0,Lm1,Lm2,Lm3,..
+C    with the last four entries repeated a safe number of times.
+C  * Consider expanding feed-in code in order to avoid zeroing registers.
+C  * Zero consistently with xor.
+C  * Check if using "lea (reg),reg" should be done in more places; we have some
+C    explicit "mov %rax,reg" now.
+C  * Try zeroing with xor in m2 loops.
+C  * Try re-rolling the m2 loops to avoid the current 9 insn code duplication
+C    between loop header and wind-down code.
+C  * Consider adc reg,reg instead of adc $0,reg in m2 loops.  This save a byte.
+
+C When playing with pointers, set this to $2 to fall back to conservative
+C indexing in wind-down code.

+C  * Suppress more rp[] rewrites in corner.
+C  * Rearrange feed-in jumps for short branch forms.
+C  * Perhaps roll out the heavy artillery and 8-way unroll outer loop.  Since
+C    feed-in code implodes, the blow-up will not be more than perhaps 4x.
+C  * Micro-optimise critical lead-in code block around L(ent).
+C  * Write n < 4 code specifically for Broadwell (current code is for Haswell).

+C TODO
+C  * We have 8 addmul_1 loops which fall into each other.  The idea is to save
+C    on switching code, since a circularly updated computed goto target will
+C    hardly allow correct branch prediction.  On 2nd thought, we now might make
+C    each of the 8 loop branches be poorly predicted since they will be
+C    executed fewer times for each time.  With just one addmul_1 loop, the loop
+C    count will change only once each 8th time.
+C  * Do overlapped software pipelining.
+C  * Perhaps load in shrx/sarx, eliminating separate load insn.
+C  * Schedule add+stored in small n code.
+C  * Try swapping adox and adcx insn, making mulx have more time to run.

+C The inner loops of this code are the result of running a code generation and
+C optimisation tool suite written by David Harvey and Torbjörn Granlund, except
+C that the sqr_diag_addlsh1 loop was manually written.
+
+C TODO
+C  * Replace current unoptimised sqr_diag_addlsh1 loop; 1.75 c/l might be
+C    possible.
+C  * Consider splitting outer loop into 2, one for n = 1 (mod 2) and one for
+C    n = 0 (mod 2).  These loops could fall into specific "corner" code.
+C  * Consider splitting outer loop into 4.
+C  * Streamline pointer updates.
+C  * Perhaps suppress a few more xor insns in feed-in code.
+C  * Make sure we write no dead registers in feed-in code.
+C  * We might use 32-bit size ops, since n >= 2^32 is non-terminating.  Watch
+C    out for negative sizes being zero-extended, though.
+C  * Provide straight-line code for n = 4; then look for simplifications in
+C    main code.

+C The loop of this code was manually written.  It runs close to optimally on
+C Intel SBR, IBR, and HWL far as we know, except for the fluctuation problems.
+C It also runs slightly faster on average on AMD bd1 and bd2.
+C
+C No micro-optimisation has been done.
+C
+C N.B.!  The loop alignment padding insns are executed.  If editing the code,
+C make sure the padding does not become excessive.  It is now a 4-byte nop.

+C NOTES
+C  * It might seem natural to use the cmov insn here, but since this function
+C    is supposed to have the exact same execution pattern for cnd true and
+C    false, and since cmov's documentation is not clear about whether it
+C    actually reads both source operands and writes the register for a false
+C    condition, we cannot use it.
+C  * Given that we have a dedicated cnd_add_n, it might look strange that this
+C    file provides cnd_add_n and not just cnd_sub_n.  But that's harmless, and
+C    this file's generality might come in handy for some pipeline.

+C  * Improve feed-in code, avoiding zeroing of many registers and dummy adds in
+C    the loops at the expense of code size.
+C  * Adjoin a mul_3, avoiding slow mul_1 for odd vn.
+C  * Consider replacing the 2-way mul_2 code with 4-way code, for a very slight
+C    speedup.
+C  * Further micro-optimise.

+C The inner loops of this code are the result of running a code generation and
+C optimisation tool suite written by David Harvey and Torbjörn Granlund, except
+C that the sqr_diag_addlsh1 loop was manually written.
+
+C TODO
+C  * Replace current unoptimised sqr_diag_addlsh1 loop, 2.5 c/l should be easy.
+C  * Streamline pointer updates.
+C  * Perhaps suppress a few more xor insns in feed-in code.
+C  * Make sure we write no dead registers in feed-in code.
+C  * We might use 32-bit size ops, since n >= 2^32 is non-terminating.  Watch
+C    out for negative sizes being zero-extended, though.
+C  * The straight-line code for n <= 3 comes from the K8 code, and might be
+C    quite sub-optimal here.  Write specific code, and add code for n = 4.
+C  * The mul_2 loop has a 10 insn common sequence in the loop start and the
+C    wind-down code.  Try re-rolling it.
+C  * This file has been the subject to just basic micro-optimisation.
+
+C When playing with pointers, set this to $2 to fall back to conservative
+C indexing in wind-down code.

+
+Intel Conroe/Penryn is a border case; its handling of non-aligned
+128-bit memory operands is poor.  VIA Nano also have poor handling of

+C We try to do as many 16-byte operations as possible.  The top-most and
+C bottom-most writes might need 8-byte operations.  We can always write using
+C aligned 16-byte operations, we read with both aligned and unaligned 16-byte
+C operations.
+
+C Instead of having separate loops for reading aligned and unaligned, we read
+C using MOVDQU.  This seems to work great except for core2; there performance
+C doubles when reading using MOVDQA (for aligned source).  It is unclear how to
+C best handle the unaligned case there.

+C We try to do as many 16-byte operations as possible.  The top-most and
+C bottom-most writes might need 8-byte operations.  We can always write using
+C aligned 16-byte operations, we read with both aligned and unaligned 16-byte
+C operations.
+
+C Instead of having separate loops for reading aligned and unaligned, we read
+C using MOVDQU.  This seems to work great except for core2; there performance
+C doubles when reading using MOVDQA (for aligned source).  It is unclear how to
+C best handle the unaligned case there.

+C We try to do as many 16-byte operations as possible.  The top-most and
+C bottom-most writes might need 8-byte operations.  We can always write using
+C aligned 16-byte operations, we read with both aligned and unaligned 16-byte
+C operations.
+
+C Instead of having separate loops for reading aligned and unaligned, we read
+C using MOVDQU.  This seems to work great except for core2; there performance
+C doubles when reading using MOVDQA (for aligned source).  It is unclear how to
+C best handle the unaligned case there.

+C We try to do as many 16-byte operations as possible.  The top-most and
+C bottom-most writes might need 8-byte operations.  We always write using
+C 16-byte operations, we read with both 8-byte and 16-byte operations.
+
+C There are two inner-loops, one for when rp = ap (mod 16) and one when this is
+C not true.  The aligned case reads 16+8 bytes, the unaligned case reads
+C 16+8+X bytes, where X is 8 or 16 depending on how punpcklqdq is implemented.
+
+C This is not yet great code:
+C   (1) The unaligned case makes too many reads.
+C   (2) We should do some unrolling, at least 2-way.
+C With 2-way unrolling but no scheduling we reach 1.5 c/l on K10 and 2 c/l on
+C Nano.

+dnl
+dnl  For non-PIC, the jumps are 5 bytes each, aligning them to 8 should be

+dnl  Usage: FAT_INIT(name, offset)
+dnl
+dnl  Emit a fat binary initializer function of the given name.  These
+dnl  functions are the initial values for the pointers in __gmpn_cpuvec.
+dnl
+dnl  The code simply calls __gmpn_cpuvec_init, and then jumps back through
+dnl  the __gmpn_cpuvec pointer, at the given "offset" (in bytes).
+dnl  __gmpn_cpuvec_init will have stored the address of the selected
+dnl  implementation there.
+dnl
+dnl  Only one of these routines will be executed, and only once, since after
+dnl  that all the __gmpn_cpuvec pointers go to real routines.  So there's no
+dnl  need for anything special here, just something small and simple.  To
+dnl  keep code size down, "fat_init" is a shared bit of code, arrived at
+dnl  with the offset in %al.  %al is used since the movb instruction is 2
+dnl  bytes where %eax would be 4.
+dnl
+dnl  Note having `PROLOGUE in FAT_INIT obscures that PROLOGUE from the
+dnl  HAVE_NATIVE grepping in configure, preventing that code trying to eval
+dnl  something with $1 in it.
+dnl
+dnl  We need to preserve parameter registers over the __gmpn_cpuvec_init call

+C  * Use fewer registers.  (how??? I can't see it -- david)
+C  * Avoid some "mov $0,r" and instead use "xor r,r".
+C  * Can the top of each L(addmul_outer_n) prologue be folded into the
+C    mul_1/mul_2 prologues, saving a LEA (%rip)? It would slow down the
+C    case where vn = 1 or 2; is it worth it?

+C optimisation tool suite written by David Harvey and Torbjorn Granlund.
+
+C NOTES
+C   * There is a major stupidity in that we call mpn_mul_1 initially, for a
+C     large trip count.  Instead, we should start with mul_2 for any operand
+C     size congruence class.
+C   * Stop iterating addmul_2 earlier, falling into straight-line triangle code
+C     for the last 2-3 iterations.
+C   * Perhaps implement n=4 special code.
+C   * The reload of the outer loop jump address hurts branch prediction.
+C   * The addmul_2 loop ends with an MUL whose high part is not used upon loop
+C     exit.

+
+C TODO
+C  * Micro-optimise, none performed thus far.
+C  * This looks different from other current redc_1.asm variants.  Consider
+C    adapting this to the mainstream style.
+C  * Is this code really faster than more approaches which compute q0 later?
+C    Is the use of a jump jump table faster?  Or is the edge of this due to the
+C    inlined add_n code?
+C  * Put initial m[0] x q0 computation in header.
+C  * Put basecases at the file's end, single them out before the pushes.

+C The inner loops of this code are the result of running a code generation and
+C optimization tool suite written by David Harvey and Torbjorn Granlund.
+
+C NOTES
+C   * There is a major stupidity in that we call mpn_mul_1 initially, for a
+C     large trip count.  Instead, we should follow the generic/sqr_basecase.c
+C     code which uses addmul_2s from the start, conditionally leaving a 1x1
+C     multiply to the end.  (In assembly code, one would stop invoking
+C     addmul_2s loops when perhaps 3x2s respectively a 2x2s remains.)
+C   * Another stupidity is in the sqr_diag_addlsh1 code.  It does not need to
+C     save/restore carry, instead it can propagate into the high product word.
+C   * Align more labels, should shave off a few cycles.
+C   * We can safely use 32-bit size operations, since operands with (2^32)
+C     limbs will lead to non-termination in practice.
+C   * The jump table could probably be optimized, at least for non-pic.
+C   * The special code for n <= 4 was quickly written.  It is probably too
+C     large and unnecessarily slow.
+C   * Consider combining small cases code so that the n=k-1 code jumps into the
+C     middle of the n=k code.
+C   * Avoid saving registers for small cases code.
+C   * Needed variables:
+C    n   r11  input size
+C    i   r8   work left, initially n
+C    j   r9   inner loop count
+C        r15  unused

+C Note: This implementation needs B1modb only when cnt > 0
+
+C The iteration is almost as follows,
+C
+C   r_2 B^3 + r_1 B^2 + r_0 B + u = r_1 B2modb + (r_0 + r_2 B2mod) B + u
+C
+C where r2 is a single bit represented as a mask. But to make sure that the
+C result fits in two limbs and a bit, carry from the addition
+C
+C   r_0 + r_2 B2mod
+C
+C is handled specially. On carry, we subtract b to cancel the carry,
+C and we use instead the value
+C
+C   r_0 + B2mb (mod B)
+C
+C This addition can be issued early since it doesn't depend on r2, and it is
+C the source of the cmov in the loop.
+C
+C We have the invariant that r_2 B^2 + r_1 B + r_0 < B^2 + B b

+C the latency otherwise.
+C
+C The l=src[i]-cbit step is rotated back too, since that allows us to avoid it
+C for the first iteration (where there's no cbit).
+C
+C The code alignment used (32-byte) for the loop also seems necessary.  Without
+C that the non-PIC case has adc crossing the 0x60 offset, apparently making it

+C TODO
+C  * Try 2x unrolling instead of current 4x, at least for mul_1.  Else consider
+C    shallower sw pipelining of mul_1/addmul_1 loops, allowing 4 or 6 instead
+C    of 8 product registers.
+C  * Split up mul_1 into 4 loops in order to fall into the addmul_1 loops
+C    without branch tree.
+C  * Improve the overlapped software pipelining.  The mulx in the osp block now
+C    suffers from write/read conflicts, in particular the 1 mod 4 case.  Also,
+C    mul_1 could osp into addmul_1.
+C  * Let vn_param be vn to save a copy.
+C  * Re-allocate to benefit more from 32-bit encoding.
+C  * Poor performance for e.g. n = 12,16.

+C  * Rearrange feed-in jumps for short branch forms.
+C  * Roll out the heavy artillery and 4-way unroll outer loop.  Since feed-in
+C    code implodes, the blow-up will not be more than perhaps 2.5x.
+C  * Micro-optimise critical lead-in code blocks.
+C  * Clean up register use, e.g. r15 vs vp, disuse of nn, etc.
+C  * Write n < 4 code specifically for Zen (current code is for Haswell).

+C TODO
+C  * The o1...o8  loops for special dn counts were naively hand-optimised by
+C    folding the generic loops.  They can probably be tuned.  The speculative
+C    quotient limb generation might not be in the optimal spot.
+C  * Perhaps avoid late-in-loop jumps, e.g., lo0.
+C  * Improve regalloc wrt dn_param/dn and un_param/un to save some moves.

+C TODO
+C  * Do overlapped software pipelining.  This should close the remaining gap to
+C    mul_basecase.
+C
+C  * Update un just once in the outer loop.
+C
+C  * Perhaps keep un and n pre-multiplied by 8, thus suppressing ",8" from
+C    loads and stores.  At least in some cases, the non-scaled form is faster.
+C
+C  * Optimise xit3 code, e.g., using shrx and sarx like in the main loop.
+C
+C  * The mul_1 feed-in code has gotten little attention and could probably be
+C    improved.  Perhaps even expand it to 4 separate loops to allow straight
+C    fall-through into the 4 addmul_1 loops.
+C
+C  * Clean up ad-hoc scratch register usage in the addmul_1 feed-in code blocks.

+/* All that's needed is to get the high 53 bits of the quotient num/den,
+   rounded towards zero.  More than 53 bits is fine, any excess is ignored
+   by mpn_get_d.
+
+   N_QLIMBS is how many quotient limbs we need to satisfy the mantissa of a
+   double, assuming the highest of those limbs is non-zero.  The target
+   qsize for mpn_tdiv_qr is then 1 more than this, since that function may
+   give a zero in the high limb (and non-zero in the second highest).
+
+   The use of 8*sizeof(double) in N_QLIMBS is an overestimate of the
+   mantissa bits, but it gets the same result as the true value (53 or 48 or
+   whatever) when rounded up to a multiple of GMP_NUMB_BITS, for non-nails.
+
+   Enhancements:
+
+   Use the true mantissa size in the N_QLIMBS formula, to save a divide step
+   in nails.
+
+   Examine the high limbs of num and den to see if the highest 1 bit of the
+   quotient will fall high enough that just N_QLIMBS-1 limbs is enough to
+   get the necessary bits, thereby saving a division step.
+
+   Bit shift either num or den to arrange for the above condition on the
+   high 1 bit of the quotient, to save a division step always.  A shift to
+   save a division step is definitely worthwhile with mpn_tdiv_qr, though we
+   may want to reassess this on big num/den when a quotient-only division
+   exists.
+
+   Maybe we could estimate the final exponent using nsize-dsize (and
+   possibly the high limbs of num and den), so as to detect overflow and
+   return infinity or zero quickly.  Overflow is never very helpful to an
+   application, and can therefore probably be regarded as abnormal, but we
+   may still like to optimize it if the conditions are easy.  (This would
+   only be for float formats we know, unknown formats are not important and
+   can be left to mpn_get_d.)
+
+   Future:
+
+   If/when mpn_tdiv_qr supports its qxn parameter we can use that instead of
+   padding n with zeros in temporary space.
+
+   Alternatives:
+
+   An alternative algorithm, that may be faster:
+   0. Let n be somewhat larger than the number of significant bits in a double.
+   1. Extract the most significant n bits of the denominator, and an equal
+      number of bits from the numerator.
+   2. Interpret the extracted numbers as integers, call them a and b
+      respectively, and develop n bits of the fractions ((a + 1) / b) and
+      (a / (b + 1)) using mpn_divrem.
+   3. If the computed values are identical UP TO THE POSITION WE CARE ABOUT,
+      we are done.  If they are different, repeat the algorithm from step 1,
+      but first let n = n * 2.
+   4. If we end up using all bits from the numerator and denominator, fall
+      back to a plain division.
+   5. Just to make life harder, The computation of a + 1 and b + 1 above
+      might give carry-out...  Needs special handling.  It might work to
+      subtract 1 in both cases instead.
+
+   Not certain if this approach would be faster than a quotient-only
+   division.  Presumably such optimizations are the sort of thing we would
+   like to have helping everywhere that uses a quotient-only division. */

+/* Algorithm:
+
+   Accumulate chunks of factors first limb-by-limb (using one of mul0-mul8)
+   which are then accumulated into mpn numbers.  The first inner loop
+   accumulates divisor factors, the 2nd inner loop accumulates exactly the same
+   number of dividend factors.  We avoid accumulating more for the divisor,
+   even with its smaller factors, since we else cannot guarantee divisibility.
+
+   Since we know each division will yield an integer, we compute the quotient
+   using Hensel norm: If the quotient is limited by 2^t, we compute A / B mod
+   2^t.
+
+   Improvements:
+
+   (1) An obvious improvement to this code would be to compute mod 2^t
+   everywhere.  Unfortunately, we cannot determine t beforehand, unless we
+   invoke some approximation, such as Stirling's formula.  Of course, we don't
+   need t to be tight.  However, it is not clear that this would help much,
+   our numbers are kept reasonably small already.
+
+   (2) Compute nmax/kmax semi-accurately, without scalar division or a loop.
+   Extracting the 3 msb, then doing a table lookup using cnt*8+msb as index,
+   would make it both reasonably accurate and fast.  (We could use a table
+   stored into a limb, perhaps.)  The table should take the removed factors of
+   2 into account (those done on-the-fly in mulN).
+
+   (3) The first time in the loop we compute the odd part of a
+   factorial in kp, we might use oddfac_1 for this task.

+   and so isn't done for the moment.
+
+   Low zero limbs on d could be stripped and the corresponding limbs of a

+   limb because the result F[2k+1] is an F[4m+3] and such numbers are always
+   == 1, 2 or 5 mod 8, whereas an underflow would leave 6 or 7.  (This is
+   the same as in mpn_fib2_ui.)
+
+   In the F[2k+1] for k even, the +2 won't give a carry out of the low limb
+   in normal circumstances.  This is an F[4m+1] and we claim that F[3*2^b+1]
+   == 1 mod 2^b is the first F[4m+1] congruent to 0 or 1 mod 2^b, and hence
+   if n < 2^GMP_NUMB_BITS then F[n] cannot have a low limb of 0 or 1.  No
+   proof for this claim, but it's been verified up to b==32 and has such a
+   nice pattern it must be true :-).  Of interest is that F[3*2^b] == 0 mod
+   2^(b+1) seems to hold too.
+
+   When n >= 2^GMP_NUMB_BITS, which can arise in a nails build, then the low

+/* mpz_millerrabin(n,reps) -- An implementation of the probabilistic primality
+   test found in Knuth's Seminumerical Algorithms book.  If the function
+   mpz_millerrabin() returns 0 then n is not prime.  If it returns 1, then n is
+   'probably' prime.  The probability of a false positive is (1/4)**reps, where
+   reps is the number of internal passes of the probabilistic algorithm.  Knuth
+   indicates that 25 passes are reasonable.
+
+   With the current implementation, the first 24 MR-tests are substituted by a
+   Baillie-PSW probable prime test.
+
+   This implementation the Baillie-PSW test was checked up to 19*2^46,
+   for smaller values no MR-test is performed, regardless of reps, and
+   2 ("surely prime") is returned if the number was not proved composite.
+
+   If GMP_BPSW_NOFALSEPOSITIVES_UPTO_64BITS is defined as non-zero,
+   the code assumes that the Baillie-PSW test was checked up to 2^64.
+

+   ui_pow_ui doesn't need the mpn_mul based powering loop or the tests on
+   bsize==2 or >2, but separating that isn't easy because there's shared
+   code both before and after (the size calculations and the powers of 2
+   handling).
+
+   Alternatives:
+
+   It would work to just use the mpn_mul powering loop for 1 and 2 limb
+   bases, but the current separate loop allows mul_1 and mul_2 to be done
+   in-place, which might help cache locality a bit.  If mpn_mul was relaxed
+   to allow source==dest when vn==1 or 2 then some pointer twiddling might
+   let us get the same effect in one loop.
+
+   The initial powering for bsize==1 into blimb or blimb:blimb_low doesn't
+   form the biggest possible power of b that fits, only the biggest power of
+   2 power, ie. b^(2^n).  It'd be possible to choose a bigger power, perhaps
+   using mp_bases[b].big_base for small b, and thereby get better value
+   from mpn_mul_1 or mpn_mul_2 in the bignum powering.  It's felt that doing
+   so would be more complicated than it's worth, and could well end up being
+   a slowdown for small e.  For big e on the other hand the algorithm is
+   dominated by mpn_sqr so there wouldn't much of a saving.  The current
+   code can be viewed as simply doing the first few steps of the powering in
+   a single or double limb where possible.
+
+   If r==b, and blow_twos==0, and r must be realloc'ed, then the temporary
+   copy made of b is unnecessary.  We could just use the old alloc'ed block
+   and free it at the end.  But arranging this seems like a lot more trouble
+   than it's worth.  */

+/* mpz_probab_prime_p --
+   An implementation of the probabilistic primality test found in Knuth's
+   Seminumerical Algorithms book.  If the function mpz_probab_prime_p()
+   returns 0 then n is not prime.  If it returns 1, then n is 'probably'
+   prime.  If it returns 2, n is surely prime.  The probability of a false
+   positive is (1/4)**reps, where reps is the number of internal passes of the
+   probabilistic algorithm.  Knuth indicates that 25 passes are reasonable.

+  Optimisation ideas:

+     improvement.
+
+  2. Separate sieving with primes p < SIEVESIZE and p >= SIEVESIZE.  The latter
+     will need at most one write, and thus not need any inner loop.
+
+  3. For primes p >= SIEVESIZE, i.e., typically the majority of primes, we
+     perform more than one division per sieving write.  That might dominate the
+     entire run time for the nextprime function.  A incrementally initialised
+     remainder table of Pi(65536) = 6542 16-bit entries could replace that

+/* printf is convenient because it allows various types to be printed in one
+   fairly compact call, so having gmp_printf support the standard types as
+   well as the gmp ones is important.  This ends up meaning all the standard
+   parsing must be duplicated, to get a new routine recognising the gmp
+   extras.
+
+   With the currently favoured handling of mpz etc as Z, Q and F type
+   markers, it's not possible to use glibc register_printf_function since
+   that only accepts new conversion characters, not new types.  If Z was a
+   conversion there'd be no way to specify hex, decimal or octal, or
+   similarly with F no way to specify fixed point or scientific format.
+
+   It seems wisest to pass conversions %f, %e and %g of float, double and
+   long double over to the standard printf.  It'd be hard to be sure of
+   getting the right handling for NaNs, rounding, etc.  Integer conversions
+   %d etc and string conversions %s on the other hand could be easily enough
+   handled within gmp_doprnt, but if floats are going to libc then it's just
+   as easy to send all non-gmp types there.
+
+   "Z" was a type marker for size_t in old glibc, but there seems no need to
+   provide access to that now "z" is standard.
+
+   In GMP 4.1.1 we documented "ll" and "L" as being equivalent, but in C99
+   in fact "ll" is just for long long and "L" just for long double.
+   Apparently GLIBC allows "L" for long long though.  This doesn't affect
+   us as such, since both are passed through to the C library.  To be
+   consistent with what we said before, the two are treated equivalently
+   here, and it's left to the C library to do what it thinks with them.
+
+   Possibilities:
+
+   "b" might be nice for binary output, and could even be supported for the
+   standard C types too if desired.
+
+   POSIX style "%n$" parameter numbering would be possible, but would need
+   to be handled completely within gmp_doprnt, since the numbering will be
+   all different once the format string it cut into pieces.
+
+   Some options for mpq formatting would be good.  Perhaps a non-zero
+   precision field could give a width for the denominator and mean always
+   put a "/".  A form "n+p/q" might interesting too, though perhaps that's
+   better left to applications.
+
+   Right now there's no way for an application to know whether types like
+   intmax_t are supported here.  If configure is doing its job and the same
+   compiler is used for gmp as for the application then there shouldn't be
+   any problem, but perhaps gmp.h should have some preprocessor symbols to
+   say what libgmp can do.  */

+   nothing in between then we'll reach here with this_fmt == last_fmt and we

+/* State structure for LC, the RNG_STATE() pointer in a gmp_randstate_t.
+
+   _mp_seed holds the current seed value, in the range 0 to 2^m2exp-1.
+   SIZ(_mp_seed) is fixed at BITS_TO_LIMBS(_mp_m2exp) and the value is
+   padded with high zero limbs if necessary.  ALLOC(_mp_seed) is the current
+   size of PTR(_mp_seed) in the usual way.  There only needs to be
+   BITS_TO_LIMBS(_mp_m2exp) allocated, but the mpz functions in the
+   initialization and seeding end up making it a bit more than this.
+
+   _mp_a is the "a" multiplier, in the range 0 to 2^m2exp-1.  SIZ(_mp_a) is
+   the size of the value in the normal way for an mpz_t, except that a value
+   of zero is held with SIZ(_mp_a)==1 and PTR(_mp_a)[0]==0.  This makes it
+   easy to call mpn_mul, and the case of a==0 is highly un-random and not
+   worth any trouble to optimize.
+
+   {_cp,_cn} is the "c" addend.  Normally _cn is 1, but when nails are in
+   use a ulong can be bigger than one limb, and in this case _cn is 2 if
+   necessary.  c==0 is stored as _cp[0]==0 and _cn==1, which makes it easy
+   to call __GMPN_ADD.  c==0 is fairly un-random so isn't worth optimizing.
+
+   _mp_m2exp gives the modulus, namely 2^m2exp.  We demand m2exp>=1, since
+   m2exp==0 would mean no bits at all out of each iteration, which makes no
+   sense.  */

+/* Seeding function.  Uses powering modulo a non-Mersenne prime to obtain
+   a permutation of the input seed space.  The modulus is 2^19937-20023,
+   which is probably prime.  The power is 1074888996.  In order to avoid
+   seeds 0 and 1 generating invalid or strange output, the input seed is
+   first manipulated as follows:
+
+     seed1 = seed mod (2^19937-20027) + 2
+
+   so that seed1 lies between 2 and 2^19937-20026 inclusive. Then the
+   powering is performed as follows:
+
+     seed2 = (seed1^1074888996) mod (2^19937-20023)
+
+   and then seed2 is used to bootstrap the buffer.
+
+   This method aims to give guarantees that:
+     a) seed2 will never be zero,
+     b) seed2 will very seldom have a very low population of ones in its
+	binary representation, and
+     c) every seed between 0 and 2^19937-20028 (inclusive) will yield a
+	different sequence.
+
+   CAVEATS:
+
+   The period of the seeding function is 2^19937-20027.  This means that
+   with seeds 2^19937-20027, 2^19937-20026, ... the exact same sequences
+   are obtained as with seeds 0, 1, etc.; it also means that seed -1
+   produces the same sequence as seed 2^19937-20028, etc.

+/* General:
+
+       It's necessary to parse up the format string to recognise the GMP
+       extra types F, Q and Z.  Other types and conversions are passed
+       across to the standard sscanf or fscanf via funs->scan, for ease of
+       implementation.  This is essential in the case of something like glibc
+       %p where the pointer format isn't actually documented.
+
+       Because funs->scan doesn't get the whole input it can't put the right
+       values in for %n, so that's handled in __gmp_doscan.  Neither sscanf
+       nor fscanf directly indicate how many characters were read, so an
+       extra %n is appended to each run for that.  For fscanf this merely
+       supports our %n output, but for sscanf it lets funs->step move us
+       along the input string.
+
+       Whitespace and literal matches in the format string, including %%,
+       are handled directly within __gmp_doscan.  This is reasonably
+       efficient, and avoids some suspicious behaviour observed in various
+       system libc's.  GLIBC 2.2.4 for instance returns 0 on
+
+	   sscanf(" ", " x")
+       or
+	   sscanf(" ", " x%d",&n)
+
+       whereas we think they should return EOF, since end-of-string is
+       reached when a match of "x" is required.
+
+       For standard % conversions, funs->scan is called once for each
+       conversion.  If we had vfscanf and vsscanf and could rely on their
+       fixed text matching behaviour then we could call them with multiple
+       consecutive standard conversions.  But plain fscanf and sscanf work
+       fine, and parsing one field at a time shouldn't be too much of a
+       slowdown.
+
+   gmpscan:
+
+       gmpscan reads a gmp type.  It's only used from one place, but is a
+       separate subroutine to avoid a big chunk of complicated code in the
+       middle of __gmp_doscan.  Within gmpscan a couple of loopbacks make it
+       possible to share code for parsing integers, rationals and floats.
+
+       In gmpscan normally one char of lookahead is maintained, but when width
+       is reached that stops, on the principle that an fgetc/ungetc of a char
+       past where we're told to stop would be undesirable.  "chars" is how many
+       characters have been read so far, including the current c.  When
+       chars==width and another character is desired then a jump is done to the
+       "convert" stage.  c is invalid and mustn't be unget'ed in this case;
+       chars is set to width+1 to indicate that.
+
+       gmpscan normally returns the number of characters read.  -1 means an
+       invalid field, -2 means EOF reached before any matching characters
+       were read.
+
+       For hex floats, the mantissa part is passed to mpf_set_str, then the
+       exponent is applied with mpf_mul_exp or mpf_div_2exp.  This is easier
+       than teaching mpf_set_str about an exponent factor (ie. 2) differing
+       from the mantissa radix point factor (ie. 16).  mpf_mul_exp and
+       mpf_div_2exp will preserve the application requested precision, so
+       nothing in that respect is lost by making this a two-step process.
+
+   Matching and errors:
+
+       C99 7.19.6.2 paras 9 and 10 say an input item is read as the longest
+       string which is a match for the appropriate type, or a prefix of a
+       match.  With that done, if it's only a prefix then the result is a
+       matching failure, ie. invalid input.
+
+       This rule seems fairly clear, but doesn't seem to be universally
+       applied in system C libraries.  Even GLIBC doesn't seem to get it
+       right, insofar as it seems to accept some apparently invalid forms.
+       Eg. glibc 2.3.1 accepts "0x" for a "%i", where a reading of the
+       standard would suggest a non-empty sequence of digits should be
+       required after an "0x".
+
+       A footnote to 7.19.6.2 para 17 notes how this input item reading can
+       mean inputs acceptable to strtol are not acceptable to fscanf.  We
+       think this confirms our reading of "0x" as invalid.
+
+       Clearly gmp_sscanf could backtrack to a longest input which was a
+       valid match for a given item, but this is not done, since C99 says
+       sscanf is identical to fscanf, so we make gmp_sscanf identical to
+       gmp_fscanf.
+
+   Types:
+
+       C99 says "ll" is for long long, and "L" is for long double floats.
+       Unfortunately in GMP 4.1.1 we documented the two as equivalent.  This
+       doesn't affect us directly, since both are passed through to plain
+       scanf.  It seems wisest not to try to enforce the C99 rule.  This is
+       consistent with what we said before, though whether it actually
+       worked was always up to the C library.
+
+   Alternatives:
+
+       Consideration was given to using separate code for gmp_fscanf and
+       gmp_sscanf.  The sscanf case could zip across a string doing literal
+       matches or recognising digits in gmpscan, rather than making a
+       function call fun->get per character.  The fscanf could use getc
+       rather than fgetc too, which might help those systems where getc is a
+       macro or otherwise inlined.  But none of this scanning and converting
+       will be particularly fast, so the two are done together to keep it a
+       little simpler for now.
+
+       Various multibyte string issues are not addressed, for a start C99
+       scanf says the format string is multibyte.  Since we pass %c, %s and
+       %[ to the system scanf, they might do multibyte reads already, but
+       it's another matter whether or not that can be used, since our digit
+       and whitespace parsing is only unibyte.  The plan is to quietly
+       ignore multibyte locales for now.  This is not as bad as it sounds,
+       since GMP is presumably used mostly on numbers, which can be
+       perfectly adequately treated in plain ASCII.

+
+   A marker is a "struct tmp_debug_t *" so that TMP_DECL can initialize it

+                       DEVELOPMENT TEST PROGRAMS
+
+
+This directory contains various programs used during development.  Casual
+GMP users are unlikely to find anything of interest.
+
+Nothing here is built or installed, nor even run in a "make check", but
+there's Makefile rules to build each program, or "allprogs" to build
+everything.

+   fill (see below) will show locations never written.
+
+   The -s option can be used to test only certain size operands, which is
+   useful if some new code doesn't yet support say sizes less than the
+   unrolling, or whatever.
+
+   When a problem occurs it'll of course be necessary to run the program
+   under gdb to find out quite where, how and why it's going wrong.  Disable
+   the spinner with the -W option when doing this, or single stepping won't
+   work.  Using the "-1" option to run with simple data can be useful.
+
+   New functions to test can be added in try_array[].  If a new TYPE is
+   required then add it to the existing constants, set up its parameters in
+   param_init(), and add it to the call() function.  Extra parameter fields
+   can be added if necessary, or further interpretations given to existing
+   fields.
+
+
+   Portability:
+
+   This program is not designed for use on Cray vector systems under Unicos,
+   it will fail to compile due to missing _SC_PAGE_SIZE.  Those systems
+   don't really have pages or mprotect.  We could arrange to run the tests
+   without the redzones, but we haven't bothered currently.
+
+
+   Enhancements:
+
+   umul_ppmm support is not very good, lots of source data is generated
+   whereas only two limbs are needed.
+
+   Make a little scheme for interpreting the "SIZE" selections uniformly.
+
+   Make tr->size==SIZE_2 work, for the benefit of find_a which wants just 2
+   source limbs.  Possibly increase the default repetitions in that case.
+
+   Automatically detect gdb and disable the spinner (use -W for now).
+
+   Make a way to re-run a failing case in the debugger.  Have an option to
+   snapshot each test case before it's run so the data is available if a
+   segv occurs.  (This should be more reliable than the current print_all()
+   in the signal handler.)
+
+   When alignment means a dst isn't hard against the redzone, check the
+   space in between remains unchanged.
+
+   When a source overlaps a destination, don't run both s[i].high 0 and 1,
+   as s[i].high has no effect.  Maybe encode s[i].high into overlap->s[i].
+
+   When partial overlaps aren't done, don't loop over source alignments
+   during overlaps.
+
+   Try to make the looping code a bit less horrible.  Right now it's pretty
+   hard to see what iterations are actually done.
+
+   Perhaps specific setups and loops for each style of function under test
+   would be clearer than a parameterized general loop.  There's lots of
+   stuff common to all functions, but the exceptions get messy.
+
+   When there's no overlap, run with both src>dst and src<dst.  A subtle
+   calling-conventions violation occurred in a P6 copy which depended on the
+   relative location of src and dst.
+
+   multiplier_N is more or less a third source region for the addmul_N
+   routines, and could be done with the redzoned region scheme.

+   GMP_ASM_TYPE in acinclude.m4.
+
+   A failure can be provoked in a shared or shared+static build by making
+   TYPE and SIZE in config.m4 empty, either by editing it or by configuring
+   with
+
+       ./configure gmp_cv_asm_type= gmp_cv_asm_size=
+
+   mpn_add_n is used for the test because normally it's implemented in
+   assembler on a CPU that has any asm code.
+
+   Enhancement: As noted with GMP_ASM_TYPE, if .type is wrong but .size is
+   right then everything works, but uses code copied down to the mainline
+   data area.  Maybe we could detect that if we built a test library with an
+   object that had .size deliberately disabled.  */

+/* In this program we're aiming to pick up certain subtle problems that
+   might creep into a fat binary.
+
+   1. We want to ensure the application entry point routines like
+      __gmpn_add_n dispatch to the correct field of __gmpn_cpuvec.
+
+      Note that these routines are not exercised as a side effect of other
+      tests (eg. the mpz routines).  Internally the fields of __gmpn_cpuvec
+      are used directly, so we need to write test code explicitly calling
+      the mpn functions, like an application will have.
+
+   2. We want to ensure the initial __gmpn_cpuvec data has the initializer
+      function pointers in the correct fields, and that those initializer
+      functions dispatch to their correct corresponding field once
+      initialization has been done.
+
+      Only one of the initializer routines executes in a normal program,
+      since that routine sets all the pointers to actual mpn functions.  We
+      forcibly reset __gmpn_cpuvec so we can run each.
+
+   In both cases for the above, the data put through the functions is
+   nothing special, just enough to verify that for instance an add_n is
+   really doing an add_n and has not for instance mistakenly gone to sub_n
+   or something.
+
+   The loop around each test will exercise the initializer routine on the
+   first iteration, and the dispatcher routine on the second.
+
+   If the dispatcher and/or initializer routines are generated mechanically
+   via macros (eg. mpn/x86/fat/fat_entry.asm) then there shouldn't be too
+   much risk of them going wrong, provided the structure layout is correctly
+   expressed.  But if they're in C then it's good to guard against typos in
+   what is rather repetitive code.  The initializer data for __gmpn_cpuvec
+   in fat.c is always done by hand and is likewise a bit repetitive.  */

+The Kolmogorov-Smirnov test.
+
+Eq. (13) in Knuth, p. 50, says that if X1, X2, ..., Xn are independent
+observations arranged into ascending order
+
+	Kp = sqr(n) * max(j/n - F(Xj))		for all 1<=j<=n
+	Km = sqr(n) * max(F(Xj) - (j-1)/n))	for all 1<=j<=n
+
+where F(x) = Pr(X <= x) = probability that (X <= x), which for a
+uniformly distributed random real number between zero and one is
+exactly the number itself (x).
+
+
+The answer to exercise 23 gives the following implementation, which
+doesn't need the observations to be sorted in ascending order:
+
+for (k = 0; k < m; k++)
+	a[k] = 1.0
+	b[k] = 0.0
+	c[k] = 0
+
+for (each observation Xj)
+	Y = F(Xj)
+	k = floor (m * Y)
+	a[k] = min (a[k], Y)
+	b[k] = max (b[k], Y)
+	c[k] += 1
+
+	j = 0
+	rp = rm = 0
+	for (k = 0; k < m; k++)
+		if (c[k] > 0)
+			rm = max (rm, a[k] - j/n)
+			j += c[k]
+			rp = max (rp, j/n - b[k])

+               GMP SPEED MEASURING AND PARAMETER TUNING
+
+
+The programs in this directory are for knowledgeable users who want to
+measure GMP routines on their machine, and perhaps tweak some settings or
+identify things that can be improved.
+
+The programs here are tools, not ready to run solutions.  Nothing is built
+in a normal "make all", but various Makefile targets described below exist.
+
+Relatively few systems and CPUs have been tested, so be sure to verify that
+results are sensible before relying on them.
+
+
+
+
+MISCELLANEOUS NOTES
+
+--enable-assert
+
+    Don't configure with --enable-assert, since the extra code added by
+    assertion checking may influence measurements.
+
+Direct mapped caches
+
+    Some effort has been made to accommodate CPUs with direct mapped caches,
+    by putting data blocks more or less contiguously on the stack.  But this
+    will depend on TMP_ALLOC using alloca, and even then it may or may not
+    be enough.
+
+FreeBSD 4.2 i486 getrusage
+
+    This getrusage seems to be a bit doubtful, it looks like it's
+    microsecond accurate, but sometimes ru_utime remains unchanged after a
+    time of many microseconds has elapsed.  It'd be good to detect this in
+    the time.c initializations, but for now the suggestion is to pretend it
+    doesn't exist.
+
+        ./configure ac_cv_func_getrusage=no
+
+NetBSD 1.4.1 m68k macintosh time base
+
+    On this system it's been found getrusage often goes backwards, making it
+    unusable (time.c getrusage_backwards_p detects this).  gettimeofday
+    sometimes doesn't update atomically when it crosses a 1 second boundary.
+    Not sure what to do about this.  Expect possible intermittent failures.
+
+SCO OpenUNIX 8 /etc/hw
+
+    /etc/hw takes about a second to return the cpu frequency, which suggests
+    perhaps it's measuring each time it runs.  If this is annoying when
+    running the speed program repeatedly then set a GMP_CPU_FREQUENCY
+    environment variable (see TIME BASE section below).
+
+Timing on GNU/Linux
+
+    On Linux, timing currently uses the cycle counter. This is unreliable,
+    since the counter is not saved and restored at context switches (unlike
+    FreeBSD and Solaris where the cycle counter is "virtualized").
+
+    Using the clock_gettime method with CLOCK_PROCESS_CPUTIME_ID (posix) or
+    CLOCK_VIRTUAL (BSD) should be more reliable. To get clock_gettime
+    with glibc, one has to link with -lrt (which also drags in the pthreads
+    threading library). configure.in must be hacked to detect this and
+    arrange proper linking. Something like
+
+      old_LIBS="$LIBS"
+      AC_SEARCH_LIBS(clock_gettime, rt, [AC_DEFINE(HAVE_CLOCK_GETTIME)])
+      TUNE_LIBS="$LIBS"
+      LIBS="$old_LIBS"
+
+      AC_SUBST(TUNE_LIBS)
+
+    might work.
+
+Low resolution timebase
+
+    Parameter tuning can be very time consuming if the only timebase
+    available is a 10 millisecond clock tick, to the point of being
+    unusable.  This is currently the case on VAX and ARM systems.
+
+
+
+
+PARAMETER TUNING
+
+The "tuneup" program runs some tests designed to find the best settings for
+various thresholds, like MUL_TOOM22_THRESHOLD.  Its output can be put
+into gmp-mparam.h.  The program is built and run with
+
+        make tune
+
+If the thresholds indicated are grossly different from the values in the
+selected gmp-mparam.h then there may be a performance boost in applicable
+size ranges by changing gmp-mparam.h accordingly.
+
+Be sure to do a full reconfigure and rebuild to get any newly set thresholds
+to take effect.  A partial rebuild is enough sometimes, but a fresh
+configure and make is certain to be correct.
+
+If a CPU has specific tuned parameters coming from a gmp-mparam.h in one of
+the mpn subdirectories then the values from "make tune" should be similar.
+But check that the configured CPU is right and there are no machine specific
+effects causing a difference.
+
+It's hoped the compiler and options used won't have too much effect on
+thresholds, since for most CPUs they ultimately come down to comparisons
+between assembler subroutines.  Missing out on the longlong.h macros by not
+using gcc will probably have an effect.
+
+Some thresholds produced by the tune program are merely single values chosen
+from what's a range of sizes where two algorithms are pretty much the same
+speed.  When this happens the program is likely to give somewhat different
+values on successive runs.  This is noticeable on the toom3 thresholds for
+instance.
+
+
+
+
+SPEED PROGRAM
+
+The "speed" program can be used for measuring and comparing various
+routines, and producing tables of data or gnuplot graphs.  Compile it with
+
+	make speed
+
+(Or on DOS systems "make speed.exe".)
+
+Here are some examples of how to use it.  Check the code for all the
+options.
+
+Draw a graph of mpn_mul_n, stepping through sizes by 10 or a factor of 1.05
+(whichever is greater).
+
+        ./speed -s 10-5000 -t 10 -f 1.05 -P foo mpn_mul_n
+	gnuplot foo.gnuplot
+
+Compare mpn_add_n and an mpn_lshift by 1, showing times in cycles and
+showing under mpn_lshift the difference between it and mpn_add_n.
+
+	./speed -s 1-40 -c -d mpn_add_n mpn_lshift.1
+
+Using option -c for times in cycles is interesting but normally only
+necessary when looking carefully at assembler subroutines.  You might think
+it would always give an integer value, but this doesn't happen in practice,
+probably due to overheads in the time measurements.
+
+In the free-form output the "#" symbol against a measurement means the
+corresponding routine is fastest at that size.  This is a convenient visual
+cue when comparing different routines.  The graph data files <name>.data
+don't get this since it would upset gnuplot or other data viewers.
+
+
+
+
+TIME BASE
+
+The time measuring method is determined in time.c, based on what the
+configured host has available.  A cycle counter is preferred, possibly
+supplemented by another method if the counter has a limited range.  A
+microsecond accurate getrusage() or gettimeofday() will work quite well too.
+
+The cycle counters (except possibly on alpha) and gettimeofday() will depend
+on the machine being otherwise idle, or rather on other jobs not stealing
+CPU time from the measuring program.  Short routines (those that complete
+within a timeslice) should work even on a busy machine.
+
+Some trouble is taken by speed_measure() in common.c to avoid ill effects
+from sporadic interrupts, or other intermittent things (like cron waking up
+every minute).  But generally an idle machine will be necessary to be
+certain of consistent results.
+
+The CPU frequency is needed to convert between cycles and seconds, or for
+when a cycle counter is supplemented by getrusage() etc.  The speed program
+will convert as necessary according to the output format requested.  The
+tune program will work with either cycles or seconds.
+
+freq.c knows how to get the frequency on some systems, or can measure a
+cycle counter against gettimeofday() or getrusage(), but when that fails, or
+needs to be overridden, an environment variable GMP_CPU_FREQUENCY can be
+used (in Hertz).  For example in "bash" on a 650 MHz machine,
+
+	export GMP_CPU_FREQUENCY=650e6
+
+A high precision time base makes it possible to get accurate measurements in
+a shorter time.
+
+
+
+
+EXAMPLE COMPARISONS - VARIOUS
+
+Here are some ideas for things that can be done with the speed program.
+
+There's always going to be a certain amount of overhead in the time
+measurements, due to reading the time base, and in the loop that runs a
+routine enough times to get a reading of the desired precision.  Noop
+functions taking various arguments are available to measure this.  The
+"overhead" printed by the speed program each time in its intro is the "noop"
+routine, but note that this is just for information, it isn't deducted from
+the times printed or anything.
+
+	./speed -s 1 noop noop_wxs noop_wxys
+
+To see how many cycles per limb a routine is taking, look at the time
+increase when the size increments, using option -D.  This avoids fixed
+overheads in the measuring.  Also, remember many of the assembler routines
+have unrolled loops, so it might be necessary to compare times at, say, 16,
+32, 48, 64 etc to see what the unrolled part is taking, as opposed to any
+finishing off.
+
+        ./speed -s 16-64 -t 16 -C -D mpn_add_n
+
+The -C option on its own gives cycles per limb, but is really only useful at
+big sizes where fixed overheads are small compared to the code doing the
+real work.  Remember of course memory caching and/or page swapping will
+affect results at large sizes.
+
+        ./speed -s 500000 -C mpn_add_n
+
+Once a calculation stops fitting in the CPU data cache, it's going to start
+taking longer.  Exactly where this happens depends on the cache priming in
+the measuring routines, and on what sort of "least recently used" the
+hardware does.  Here's an example for a CPU with a 16kbyte L1 data cache and
+32-bit limb, showing a suddenly steeper curve for mpn_add_n at about 2000
+limbs.
+
+        ./speed -s 1-4000 -t 5 -f 1.02 -P foo mpn_add_n
+	gnuplot foo.gnuplot
+
+When a routine has an unrolled loop for, say, multiples of 8 limbs and then
+an ordinary loop for the remainder, it can happen that it's actually faster
+to do an operation on, say, 8 limbs than it is on 7 limbs.  The following
+draws a graph of mpn_sub_n, to see whether times smoothly increase with
+size.
+
+        ./speed -s 1-100 -c -P foo mpn_sub_n
+	gnuplot foo.gnuplot
+
+If mpn_lshift and mpn_rshift have special case code for shifts by 1, it
+ought to be faster (or at least not slower) than shifting by, say, 2 bits.
+
+        ./speed -s 1-200 -c mpn_rshift.1 mpn_rshift.2
+
+An mpn_lshift by 1 can be done by mpn_add_n adding a number to itself, and
+if the lshift isn't faster there's an obvious improvement that's possible.
+
+        ./speed -s 1-200 -c mpn_lshift.1 mpn_add_n_self
+
+On some CPUs (AMD K6 for example) an "in-place" mpn_add_n where the
+destination is one of the sources is faster than a separate destination.
+Here's an example to see this.  ".1" selects dst==src1 for mpn_add_n (and
+mpn_sub_n), for other values see speed.h SPEED_ROUTINE_MPN_BINARY_N_CALL.
+
+        ./speed -s 1-200 -c mpn_add_n mpn_add_n.1
+
+The gmp manual points out that divisions by powers of two should be done
+using a right shift because it'll be significantly faster than an actual
+division.  The following shows by what factor mpn_rshift is faster than
+mpn_divrem_1, using division by 32 as an example.
+
+        ./speed -s 10-20 -r mpn_rshift.5 mpn_divrem_1.32
+
+
+
+
+EXAMPLE COMPARISONS - MULTIPLICATION
+
+mul_basecase takes a ".<r>" parameter. If positive, it gives the second
+(smaller) operand size.  For example to show speeds for 3x3 up to 20x3 in
+cycles,
+
+        ./speed -s 3-20 -c mpn_mul_basecase.3
+
+A negative ".<-r>" parameter fixes the size of the product to the absolute
+value r.  For example to show speeds for 10x10 up to 19x1 in cycles,
+
+        ./speed -s 10-19 -c mpn_mul_basecase.-20
+
+mul_basecase with no parameter does an NxN multiply, so for example to show
+speeds in cycles for 1x1, 2x2, 3x3, etc, up to 20x20, in cycles,
+
+        ./speed -s 1-20 -c mpn_mul_basecase
+
+sqr_basecase is implemented by a "triangular" method on most CPUs, making it
+up to twice as fast as mul_basecase.  In practice loop overheads and the
+products on the diagonal mean it falls short of this.  Here's an example
+running the two and showing by what factor an NxN mul_basecase is slower
+than an NxN sqr_basecase.  (Some versions of sqr_basecase only allow sizes
+below SQR_TOOM2_THRESHOLD, so if it crashes at that point don't worry.)
+
+        ./speed -s 1-20 -r mpn_sqr_basecase mpn_mul_basecase
+
+The technique described above with -CD for showing the time difference in
+cycles per limb between two size operations can be done on an NxN
+mul_basecase using -E to change the basis for the size increment to N*N.
+For instance a 20x20 operation is taken to be doing 400 limbs, and a 16x16
+doing 256 limbs.  The following therefore shows the per crossproduct speed
+of mul_basecase and sqr_basecase at around 20x20 limbs.
+
+        ./speed -s 16-20 -t 4 -CDE mpn_mul_basecase mpn_sqr_basecase
+
+Of course sqr_basecase isn't really doing NxN crossproducts, but it can be
+interesting to compare it to mul_basecase as if it was.  For sqr_basecase
+the -F option can be used to base the deltas on N*(N+1)/2 operations, which
+is the triangular products sqr_basecase does.  For example,
+
+        ./speed -s 16-20 -t 4 -CDF mpn_sqr_basecase
+
+Both -E and -F are preliminary and might change.  A consistent approach to
+using them when claiming certain per crossproduct or per triangularproduct
+speeds hasn't really been established, but the increment between speeds in
+the range karatsuba will call seems sensible, that being k to k/2.  For
+instance, if the karatsuba threshold was 20 for the multiply and 30 for the
+square,
+
+        ./speed -s 10-20 -t 10 -CDE mpn_mul_basecase
+        ./speed -s 15-30 -t 15 -CDF mpn_sqr_basecase
+
+
+
+EXAMPLE COMPARISONS - MALLOC
+
+The gmp manual recommends application programs avoid excessive initializing
+and clearing of mpz_t variables (and mpq_t and mpf_t too).  Every new
+variable will at a minimum go through an init, a realloc for its first
+store, and finally a clear.  Quite how long that takes depends on the C
+library.  The following compares an mpz_init/realloc/clear to a 10 limb
+mpz_add.  Don't be surprised if the mallocing is quite slow.
+
+        ./speed -s 10 -c mpz_init_realloc_clear mpz_add
+
+On some systems malloc and free are much slower when dynamic linked.  The
+speed-dynamic program can be used to see this.  For example the following
+measures malloc/free, first static then dynamic.
+
+        ./speed -s 10 -c malloc_free
+        ./speed-dynamic -s 10 -c malloc_free
+
+Of course a real world program has big problems if it's doing so many
+mallocs and frees that it gets slowed down by a dynamic linked malloc.
+
+
+
+
+
+EXAMPLE COMPARISONS - STRING CONVERSIONS
+
+mpn_get_str does a binary to string conversion.  The base is specified with
+a ".<r>" parameter, or decimal by default.  Power of 2 bases are much faster
+than general bases.  The following compares decimal and hex for instance.
+
+        ./speed -s 1-20 -c mpn_get_str mpn_get_str.16
+
+Smaller bases need more divisions to split a given size number, and so are
+slower.  The following compares base 3 and base 9.  On small operands 9 will
+be nearly twice as fast, though at bigger sizes this reduces since in the
+current implementation both divide repeatedly by 3^20 (or 3^40 for 64 bit
+limbs) and those divisions come to dominate.
+
+        ./speed -s 1-20 -cr mpn_get_str.3 mpn_get_str.9
+
+mpn_set_str does a string to binary conversion.  The base is specified with
+a ".<r>" parameter, or decimal by default.  Power of 2 bases are faster than
+general bases on large conversions.
+
+	./speed -s 1-512 -f 2 -c mpn_set_str.8 mpn_set_str.10
+
+mpn_set_str also has some special case code for decimal which is a bit
+faster than the general case, basically by giving the compiler a chance to
+optimize some multiplications by 10.
+
+	./speed -s 20-40 -c mpn_set_str.9 mpn_set_str.10 mpn_set_str.11
+
+
+
+
+EXAMPLE COMPARISONS - GCDs
+
+mpn_gcd_1 has a threshold for when to reduce using an initial x%y when both
+x and y are single limbs.  This isn't tuned currently, but a value can be
+established by a measurement like
+
+	./speed -s 10-32 mpn_gcd_1.10
+
+This runs src[0] from 10 to 32 bits, and y fixed at 10 bits.  If the div
+threshold is high, say 31 so it's effectively disabled then a 32x10 bit gcd
+is done by nibbling away at the 32-bit operands bit-by-bit.  When the
+threshold is small, say 1 bit, then an initial x%y is done to reduce it to a
+10x10 bit operation.
+
+The threshold in mpn/generic/gcd_1.c or the various assembler
+implementations can be tweaked up or down until there's no more speedups on
+interesting combinations of sizes.  Note that this affects only a 1x1 limb
+operation and so isn't very important.  (An Nx1 limb operation always does
+an initial modular reduction, using mpn_mod_1 or mpn_modexact_1_odd.)
+
+
+
+
+SPEED PROGRAM EXTENSIONS
+
+Potentially lots of things could be made available in the program, but it's
+been left at only the things that have actually been wanted and are likely
+to be reasonably useful in the future.
+
+Extensions should be fairly easy to make though.  speed-ext.c is an example,
+in a style that should suit one-off tests, or new code fragments under
+development.
+
+many.pl is a script for generating a new speed program supplemented with
+alternate versions of the standard routines.  It can be used for measuring
+experimental code, or for comparing different implementations that exist
+within a CPU family.
+
+
+
+
+THRESHOLD EXAMINING
+
+The speed program can be used to examine the speeds of different algorithms
+to check the tune program has done the right thing.  For example to examine
+the karatsuba multiply threshold,
+
+	./speed -s 5-40 mpn_mul_basecase mpn_kara_mul_n
+
+When examining the toom3 threshold, remember it depends on the karatsuba
+threshold, so the right karatsuba threshold needs to be compiled into the
+library first.  The tune program uses specially recompiled versions of
+mpn/mul_n.c etc for this reason, but the speed program simply uses the
+normal libgmp.la.
+
+Note further that the various routines may recurse into themselves on sizes
+far enough above applicable thresholds.  For example, mpn_kara_mul_n will
+recurse into itself on sizes greater than twice the compiled-in
+MUL_TOOM22_THRESHOLD.
+
+When doing the above comparison between mul_basecase and kara_mul_n what's
+probably of interest is mul_basecase versus a kara_mul_n that does one level
+of Karatsuba then calls to mul_basecase, but this only happens on sizes less
+than twice the compiled MUL_TOOM22_THRESHOLD.  A larger value for that
+setting can be compiled-in to avoid the problem if necessary.  The same
+applies to toom3 and DC, though in a trickier fashion.
+
+There are some upper limits on some of the thresholds, arising from arrays
+dimensioned according to a threshold (mpn_mul_n), or asm code with certain
+sized displacements (some x86 versions of sqr_basecase).  So putting huge
+values for the thresholds, even just for testing, may fail.
+
+
+
+
+FUTURE
+
+Make a program to check the time base is working properly, for small and
+large measurements.  Make it able to test each available method, including
+perhaps the apparent resolution of each.
+
+Make a general mechanism for specifying operand overlap, and a syntax like
+maybe "mpn_add_n.dst=src2" to select it.  Some measuring routines do this
+sort of thing with the "r" parameter currently.

+   routine at least twice and will take the smaller time, so this might not
+   be necessary.
+
+   Data alignment will be important, for source, destination and temporary
+   workspace.  A routine can align its destination and workspace.  Programs
+   using the routines will ensure s->xp and s->yp are aligned.  Aligning
+   onto a CACHE_LINE_SIZE boundary is suggested.  s->align_wp and
+   s->align_wp2 should be respected where it makes sense to do so.
+   SPEED_TMP_ALLOC_LIMBS is a good way to do this.
+
+   A loop of the following form can be expected to turn into good assembler
+   code on most CPUs, thereby minimizing overhead in the measurement.  It
+   can always be assumed s->reps >= 1.
+
+	  i = s->reps
+	  do
+	    foo();
+	  while (--i != 0);
+
+   Additional parameters might be added to "struct speed_params" in the
+   future.  Routines should ignore anything they don't use.
+
+   s->size can be used creatively, and s->xp and s->yp can be ignored.  For
+   example, speed_mpz_fac_ui() uses s->size as n for the factorial.  s->r is
+   just a user-supplied parameter.  speed_mpn_lshift() uses it as a shift,
+   speed_mpn_mul_1() uses it as a multiplier.  */

+/* The divisions are successively dependent so latency is measured, not

+   instructions each.
+
+   Note that it's only the division which is measured here, there's no data
+   fetching and no shifting if the divisor gets normalized.
+
+   In speed_udiv_qrnnd with gcc 2.95.2 on x86 the parameters "q,r,r,q,d"
+   generate x86 div instructions with nothing in between.
+
+   The measuring function macros are in two parts to avoid overflowing
+   preprocessor expansion space if udiv_qrnnd etc are big.
+
+   Limitations:
+
+   Don't blindly use this to set UDIV_TIME in gmp-mparam.h, check the code
+   generated first.
+
+   CPUs with data-dependent divisions may want more attention paid to the
+   randomness of the data used.  Probably the measurement wanted is over

+# Usage:  cd $builddir/tune
+#	  perl $srcdir/tune/many.pl [-t] <files/dirs>...
+#
+# Output: speed-many.c
+#         try-many.c
+#         Makefile.many
+#
+# Make alternate versions of various mpn routines available for measuring
+# and testing.
+#
+# The $srcdir and $builddir in the invocation above just means the script
+# lives in the tune source directory, but should be run in the tune build
+# directory.  When not using a separate object directory this just becomes
+#
+#	cd tune
+#	perl many.pl [-t] <files/dirs>...
+#
+#
+# SINGLE FILES
+#
+# Suppose $HOME/newcode/mul_1_experiment.asm is a new implementation of
+# mpn_mul_1, then
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl $HOME/newcode/mul_1_experiment.asm
+#
+# will produce rules and renaming so that a speed program incorporating it
+# can be built,
+#
+#	make -f Makefile.many speed-many
+#
+# then for example it can be compared to the standard mul_1,
+#
+#	./speed-many -s 1-30 mpn_mul_1 mpn_mul_1_experiment
+#
+# An expanded try program can be used to check correctness,
+#
+#	make -f Makefile.many try-many
+#
+# and run
+#
+#	./try-many mpn_mul_1_experiment
+#
+# Files can be ".c", ".S" or ".asm".  ".s" files can't be used because they
+# don't get any preprocessing so there's no way to do renaming of their
+# functions.
+#
+#
+# WHOLE DIRECTORIES
+#
+# If a directory is given, then all files in it will be made available.
+# For example,
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl $HOME/newcode
+#
+# Each file should have a suffix, like "_experiment" above.
+#
+#
+# MPN DIRECTORIES
+#
+# mpn directories from the GMP source tree can be included, and this is a
+# convenient way to compare multiple implementations suiting different chips
+# in a CPU family.  For example the following would make all x86 routines
+# available,
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl `find $srcdir/mpn/x86 -type d`
+#
+# On a new x86 chip a comparison could then be made to see how existing code
+# runs.  For example,
+#
+#	make -f Makefile.many speed-many
+#	./speed-many -s 1-30 -c \
+#		mpn_add_n_x86 mpn_add_n_pentium mpn_add_n_k6 mpn_add_n_k7
+#
+# Files in "mpn" subdirectories don't need the "_experiment" style suffix
+# described above, instead a suffix is constructed from the subdirectory.
+# For example "mpn/x86/k7/mmx/mod_1.asm" will generate a function
+# mpn_mod_1_k7_mmx.  The rule is to take the last directory name after the
+# "mpn", or the last two if there's three or more.  (Check the generated
+# speed-many.c if in doubt.)
+#
+#
+# GENERIC C
+#
+# The mpn/generic directory can be included too, just like any processor
+# specific directory.  This is a good way to compare assembler and generic C
+# implementations.  For example,
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl $srcdir/mpn/generic
+#
+# or if just a few routines are of interest, then for example
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl \
+#		$srcdir/mpn/generic/lshift.c \
+#		$srcdir/mpn/generic/mod_1.c \
+#		$srcdir/mpn/generic/aorsmul_1.c
+#
+# giving mpn_lshift_generic etc.
+#
+#
+# TESTS/DEVEL PROGRAMS
+#
+# Makefile.many also has rules to build the tests/devel programs with suitable
+# renaming, and with some parameters for correctness or speed.  This is less
+# convenient than the speed and try programs, but provides an independent
+# check.  For example,
+#
+#	make -f Makefile.many tests_mul_1_experimental
+#	./tests_mul_1_experimental
+#
+# and for speed
+#
+#	make -f Makefile.many tests_mul_1_experimental_sp
+#	./tests_mul_1_experimental_sp
+#
+# Not all the programs support speed measuring, in which case only the
+# correctness test will be useful.
+#
+# The parameters for repetitions and host clock speed are -D defines.  Some
+# defaults are provided at the end of Makefile.many, but probably these will
+# want to be overridden.  For example,
+#
+#	rm tests_mul_1_experimental.o
+#	make -f Makefile.many \
+#	   CFLAGS_TESTS="-DSIZE=50 -DTIMES=1000 -DRANDOM -DCLOCK=175000000" \
+#	   tests_mul_1_experimental
+#	./tests_mul_1_experimental
+#
+#
+# OTHER NOTES
+#
+# The mappings of file names to functions, and the macros to then use for
+# speed measuring etc are driven by @table below.  The scheme isn't
+# completely general, it's only got as many variations as have been needed
+# so far.
+#
+# Some functions are only made available in speed-many, or others only in
+# try-many.  An @table entry speed=>none means no speed measuring is
+# available, or try=>none no try program testing.  These can be removed
+# if/when the respective programs get the necessary support.
+#
+# If a file has "1c" or "nc" carry-in entrypoints, they're renamed and made
+# available too.  These are recognised from PROLOGUE or MULFUNC_PROLOGUE in
+# .S and .asm files, or from a line starting with "mpn_foo_1c" in a .c file
+# (possibly via a #define), and on that basis are entirely optional.  This
+# entrypoint matching is done for the standard entrypoints too, but it would
+# be very unusual to have for instance a mul_1c without a mul_1.
+#
+# Some mpz files are recognized.  For example an experimental copy of
+# mpz/powm.c could be included as powm_new.c and would be called
+# mpz_powm_new.  So far only speed measuring is available for these.
+#
+# For the ".S" and ".asm" files, both PIC and non-PIC objects are built.
+# The PIC functions have a "_pic" suffix, for example "mpn_mod_1_k7_mmx_pic".
+# This can be ignored for routines that don't differ for PIC, or for CPUs
+# where everything is PIC anyway.
+#
+# K&R compilers are supported via the same ansi2knr mechanism used by
+# automake, though it's hard to believe anyone will have much interest in
+# measuring a compiler so old that it doesn't even have an ANSI mode.
+#
+# The "-t" option can be used to print a trace of the files found and what's
+# done with them.  A great deal of obscure output is produced, but it can
+# indicate where or why some files aren't being recognised etc.  For
+# example,
+#
+#	cd $builddir/tune
+#	perl $srcdir/tune/many.pl -t $HOME/newcode/add_n_weird.asm
+#
+# In general, when including new code, all that's really necessary is that
+# it will compile or assemble under the current configuration.  It's fine if
+# some code doesn't actually run due to bugs, or to needing a newer CPU or
+# whatever, simply don't ask for the offending routines when invoking
+# speed-many or try-many, or don't try to run them on sizes they don't yet
+# support, or whatever.
+#
+#
+# CPU SPECIFICS
+#
+# x86 - All the x86 code will assemble on any system, but code for newer
+#       chips might not run on older chips.  Expect SIGILLs from new
+#       instructions on old chips.
+#
+#       A few "new" instructions, like cmov for instance, are done as macros
+#       and will generate some equivalent plain i386 code when HAVE_HOST_CPU
+#       in config.m4 indicates an old CPU.  It won't run fast, but it does
+#       make it possible to test correctness.
+#
+#
+# INTERNALS
+#
+# The nonsense involving $ENV is some hooks used during development to add
+# additional functions temporarily.
+#
+#
+# FUTURE
+#
+# Maybe the C files should be compiled pic and non-pic too.  Wait until
+# there's a difference that might be of interest.
+#
+# Warn if a file provides no functions.
+#
+# Allow mpz and mpn files of the same name.  Currently the mpn fib2_ui
+# matching hides the mpz version of that.  Will need to check the file
+# contents to see which it is.  Would be worth allowing an "mpz_" or "mpn_"
+# prefix on the filenames to have working versions of both in one directory.
+#
+#
+# LIMITATIONS
+#
+# Some of the command lines can become very long when a lot of files are
+# included.  If this is a problem on a given system the only suggestion is
+# to run many.pl for just those that are actually wanted at a particular
+# time.
+#
+# DOS 8.3 or SysV 14 char filesystems won't work, since the long filenames
+# generated will almost certainly fail to be unique.

+/* The extension here is three versions of an mpn arithmetic mean.  These
+   aren't meant to be particularly useful, just examples.
+
+   You can run something like the following to compare their speeds.
+
+           ./speed-ext -s 1-20 -c mean_calls mean_open mean_open2
+
+   On RISC chips, mean_open() might be fastest if the compiler is doing a
+   good job.  On the register starved x86s, mean_calls will be fastest.
+
+
+   Notes:
+
+   SPEED_EXTRA_PROTOS and SPEED_EXTRA_ROUTINES are macros that get expanded
+   by speed.c in useful places.  SPEED_EXTRA_PROTOS goes after the header
+   files, and SPEED_EXTRA_ROUTINES goes in the array of available routines.
+
+   The advantage of this #include "speed.c" scheme is that there's no
+   editing of a copy of that file, and new features in new versions of it
+   will be immediately available.
+
+   In a real program the routines mean_calls() etc would probably be in
+   separate C or assembler source files, and just the measuring
+   speed_mean_calls() etc would be here.  Linking against other libraries
+   for things to measure is perfectly possible too.
+
+   When attempting to compare two versions of the same named routine, say
+   like the generic and assembler versions of mpn_add_n(), creative use of
+   cc -D or #define is suggested, so one or both can be renamed and linked
+   into the same program.  It'll be much easier to compare them side by side
+   than with separate programs for each.
+
+   common.c has notes on writing speed measuring routines.
+
+   Remember to link against tune/libspeed.la (or tune/.libs/libspeed.a if
+   not using libtool) to get common.o and other objects needed by speed.c.  */

+   unlikely if it's a system call.
+
+   speed_cyclecounter is called on the same side of the "get" for the start
+   and end measurements.  It doesn't matter how long it takes from the "get"
+   sample to the cycles sample, since that period will cancel out in the
+   difference calculation (assuming it's the same each time).
+
+   Letting the test run for more than a process time slice is probably only
+   going to reduce accuracy, especially for getrusage when the cycle counter
+   is real time, or for gettimeofday if the cycle counter is in fact process
+   time.  Use CLK_TCK/2 as a reasonable stop.
+
+   It'd be desirable to be quite accurate here.  The default speed_precision
+   for a cycle counter is 10000 cycles, so to mix that with getrusage or
+   gettimeofday the frequency should be at least that accurate.  But running
+   measurements for 10000 microseconds (or more) is too long.  Be satisfied
+   with just a half clock tick (5000 microseconds usually).  */

+
+   Having something like SPEED_ROUTINE_BINARY_N as a subroutine accepting a
+   function pointer is considered undesirable since it's not the way a
+   normal application will be calling, and some processors might do
+   different things with an indirect call, like not branch predicting, or
+   doing a full pipe flush.  At least some of the "functions" measured are
+   actually macros too.
+
+   The net effect is to bloat the object code, possibly in a big way, but
+   only what's being measured is being run, so that doesn't matter.
+
+   The loop forms don't try to cope with __GMP_ATTRIBUTE_PURE or
+   ATTRIBUTE_CONST on the called functions.  Adding a cast to a non-pure
+   function pointer doesn't work in gcc 3.2.  Using an actual non-pure
+   function pointer variable works, but stands a real risk of a
+   non-optimizing compiler generating unnecessary overheads in the call.
+   Currently the best idea is not to use those attributes for a timing
+   program build.  __GMP_NO_ATTRIBUTE_CONST_PURE will tell gmp.h and
+   gmp-impl.h to omit them from routines there.  */

+
+/* Usage:
+
+   The code in this file implements the lowest level of time measuring,
+   simple one-time measuring of time between two points.
+
+   void speed_starttime (void)
+   double speed_endtime (void)
+       Call speed_starttime to start measuring, and then call speed_endtime
+       when done.
+
+       speed_endtime returns the time taken, in seconds.  Or if the timebase
+       is in CPU cycles and the CPU frequency is unknown then speed_endtime
+       returns cycles.  Applications can identify the cycles return by
+       checking for speed_cycletime (described below) equal to 1.0.
+
+       If some sort of temporary glitch occurs then speed_endtime returns
+       0.0.  Currently this is for various cases where a negative time has
+       occurred.  This unfortunately occurs with getrusage on some systems,
+       and with the hppa cycle counter on hpux.
+
+   double speed_cycletime
+       The time in seconds for each CPU cycle.  For example on a 100 MHz CPU
+       this would be 1.0e-8.
+
+       If the CPU frequency is unknown, then speed_cycletime is either 0.0
+       or 1.0.  It's 0.0 when speed_endtime is returning seconds, or it's
+       1.0 when speed_endtime is returning cycles.
+
+       It may be noted that "speed_endtime() / speed_cycletime" gives a
+       measured time in cycles, irrespective of whether speed_endtime is
+       returning cycles or seconds.  (Assuming cycles can be had, ie. it's
+       either cycles already or the cpu frequency is known.  See also
+       speed_cycletime_need_cycles below.)
+
+   double speed_unittime
+       The unit of time measurement accuracy for the timing method in use.
+       This is in seconds or cycles, as per speed_endtime.
+
+   char speed_time_string[]
+       A null-terminated string describing the time method in use.
+
+   void speed_time_init (void)
+       Initialize time measuring.  speed_starttime() does this
+       automatically, so it's only needed if an application wants to inspect
+       the above global variables before making a measurement.
+
+   int speed_precision
+       The intended accuracy of time measurements.  speed_measure() in
+       common.c for instance runs target routines with enough repetitions so
+       it takes at least "speed_unittime * speed_precision" (this expression
+       works for both cycles or seconds from speed_endtime).
+
+       A program can provide an option so the user to set speed_precision.
+       If speed_precision is zero when speed_time_init or speed_starttime
+       first run then it gets a default based on the measuring method
+       chosen.  (More precision for higher accuracy methods.)
+
+   void speed_cycletime_need_seconds (void)
+       Call this to demand that speed_endtime will return seconds, and not
+       cycles.  If only cycles are available then an error is printed and
+       the program exits.
+
+   void speed_cycletime_need_cycles (void)
+       Call this to demand that speed_cycletime is non-zero, so that
+       "speed_endtime() / speed_cycletime" will give times in cycles.
+
+
+
+   Notes:
+
+   Various combinations of cycle counter, read_real_time(), getrusage(),
+   gettimeofday() and times() can arise, according to which are available
+   and their precision.
+
+
+   Allowing speed_endtime() to return either seconds or cycles is only a
+   slight complication and makes it possible for the speed program to do
+   some sensible things without demanding the CPU frequency.  If seconds are
+   being measured then it can always print seconds, and if cycles are being
+   measured then it can always print them without needing to know how long
+   they are.  Also the tune program doesn't care at all what the units are.
+
+   GMP_CPU_FREQUENCY can always be set when the automated methods in freq.c
+   fail.  This will be needed if times in seconds are wanted but a cycle
+   counter is being used, or if times in cycles are wanted but getrusage or
+   another seconds based timer is in use.
+
+   If the measuring method uses a cycle counter but supplements it with
+   getrusage or the like, then knowing the CPU frequency is mandatory since
+   the code compares values from the two.
+
+
+   Not done:
+
+   Solaris gethrtime() seems no more than a slow way to access the Sparc V9
+   cycle counter.  gethrvtime() seems to be relevant only to light weight
+   processes, it doesn't for instance give nanosecond virtual time.  So
+   neither of these are used.
+
+
+   Bugs:
+
+   getrusage_microseconds_p is fundamentally flawed, getrusage and
+   gettimeofday can have resolutions other than clock ticks or microseconds,
+   for instance IRIX 5 has a tick of 10 ms but a getrusage of 1 ms.
+
+
+   Enhancements:
+
+   The SGI hardware counter has 64 bits on some machines, which could be
+   used when available.  But perhaps 32 bits is enough range, and then rely
+   on the getrusage supplement.
+
+   Maybe getrusage (or times) should be used as a supplement for any
+   wall-clock measuring method.  Currently a wall clock with a good range
+   (eg. a 64-bit cycle counter) is used without a supplement.
+
+   On PowerPC the timebase registers could be used, but would have to do
+   something to find out the speed.  On 6xx chips it's normally 1/4 bus
+   speed, on 4xx chips it's either that or an external clock.  Measuring
+   against gettimeofday might be ok.  */

+/* If two times can be observed less than half a clock tick apart, then

+
+   Two times only 1 microsecond apart are not believed, since some kernels
+   take it upon themselves to ensure gettimeofday doesn't return the same
+   value twice, for the benefit of applications using it for a timestamp.
+   This is obviously very stupid given the speed of CPUs these days.
+
+   Making "reps" many calls to noop_1() is designed to waste some CPU, with
+   a view to getting measurements 2 microseconds (or more) apart.  "reps" is
+   increased progressively until such a period is seen.
+
+   The outer loop "attempts" are just to allow for any random nonsense or
+   system load upsetting the measurements (ie. making two successive calls
+   to "get" come out as a longer interval than normal).
+
+   Bugs:
+
+   The assumption that any interval less than a half tick implies
+   microsecond resolution is obviously fairly rash, the true resolution
+   could be anything between a microsecond and that half tick.  Perhaps
+   something special would have to be done on a system where this is the
+   case, since there's no obvious reliable way to detect it
+   automatically.  */

+/* Usage: tuneup [-t] [-t] [-p precision]
+
+   -t turns on some diagnostic traces, a second -t turns on more traces.
+
+   Notes:
+
+   The code here isn't a vision of loveliness, mainly because it's subject
+   to ongoing changes according to new things wanting to be tuned, and
+   practical requirements of systems tested.
+
+   Sometimes running the program twice produces slightly different results.
+   This is probably because there's so little separating algorithms near
+   their crossover, and on that basis it should make little or no difference
+   to the final speed of the relevant routines, but nothing has been done to
+   check that carefully.
+
+   Algorithm:
+
+   The thresholds are determined as follows.  A crossover may not be a
+   single size but rather a range where it oscillates between method A or
+   method B faster.  If the threshold is set making B used where A is faster
+   (or vice versa) that's bad.  Badness is the percentage time lost and
+   total badness is the sum of this over all sizes measured.  The threshold
+   is set to minimize total badness.
+
+   Suppose, as sizes increase, method B becomes faster than method A.  The
+   effect of the rule is that, as you look at increasing sizes, isolated
+   points where B is faster are ignored, but when it's consistently faster,
+   or faster on balance, then the threshold is set there.  The same result
+   is obtained thinking in the other direction of A becoming faster at
+   smaller sizes.
+
+   In practice the thresholds tend to be chosen to bring on the next
+   algorithm fairly quickly.
+
+   This rule is attractive because it's got a basis in reason and is fairly
+   easy to implement, but no work has been done to actually compare it in
+   absolute terms to other possibilities.
+
+   Implementation:
+
+   In a normal library build the thresholds are constants.  To tune them
+   selected objects are recompiled with the thresholds as global variables
+   instead.  #define TUNE_PROGRAM_BUILD does this, with help from code at
+   the end of gmp-impl.h, and rules in tune/Makefile.am.
+
+   MUL_TOOM22_THRESHOLD for example uses a recompiled mpn_mul_n.  The
+   threshold is set to "size+1" to avoid karatsuba, or to "size" to use one
+   level, but recurse into the basecase.
+
+   MUL_TOOM33_THRESHOLD makes use of the tuned MUL_TOOM22_THRESHOLD value.
+   Other routines in turn will make use of both of those.  Naturally the
+   dependants must be tuned first.
+
+   In a couple of cases, like DIVEXACT_1_THRESHOLD, there's no recompiling,
+   just a threshold based on comparing two routines (mpn_divrem_1 and
+   mpn_divexact_1), and no further use of the value determined.
+
+   Flags like USE_PREINV_MOD_1 or JACOBI_BASE_METHOD are even simpler, being
+   just comparisons between certain routines on representative data.
+
+   Shortcuts are applied when native (assembler) versions of routines exist.
+   For instance a native mpn_sqr_basecase is assumed to be always faster
+   than mpn_mul_basecase, with no measuring.
+
+   No attempt is made to tune within assembler routines, for instance
+   DIVREM_1_NORM_THRESHOLD.  An assembler mpn_divrem_1 is expected to be
+   written and tuned all by hand.  Assembler routines that might have hard
+   limits are recompiled though, to make them accept a bigger range of sizes
+   than normal, eg. mpn_sqr_basecase to compare against mpn_toom2_sqr.
+
+   Limitations:
+
+   The FFTs aren't subject to the same badness rule as the other thresholds,
+   so each k is probably being brought on a touch early.  This isn't likely
+   to make a difference, and the simpler probing means fewer tests.
