+/* The following are basic speed running routines for various gmp functions.
+ Many are very similar and use speed.h macros.
+
+ Each routine allocates it's own destination space for the result of the
+ function, because only it can know what the function needs.
+
+ speed_starttime() and speed_endtime() are put tight around the code to be
+ measured. Any setups are done outside the timed portion.
+
+ Each routine is responsible for its own cache priming.
+ speed_cache_fill() is a good way to do this, see examples in speed.h.
+ One cache priming possibility, for CPUs with write-allocate cache, and
+ functions that don't take too long, is to do one dummy call before timing
+ so as to cache everything that gets used. But speed_measure() runs a
+ 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. */
