| dnl Usage: ALIGN(bytes) |
| dnl |
| dnl Unicos assembler .align emits zeros, even in code segments, so disable |
| dnl aligning. |
| dnl |
| dnl GCC uses a macro emiting nops until the desired alignment is reached |
| dnl (see unicosmk_file_start in alpha.c). Could do something like that if |
| dnl we cared. The maximum desired alignment must be established at the |
| dnl start of the section though, since of course emitting nops only |
| dnl advances relative to the section beginning. |
