Tidy instruction separators in SHA assembly.2026-01-24T14:20:52+00:00jsing2026-01-24T14:20:52+00:00urn:sha1:1d4a03f3d650a577581aedee8cc799a3ad6668d8
Remove unnecessary separators and add a few to macros that call other
macros (instead of expecting them to exist).
Use .section before .rodata to appease gas.2026-01-17T06:31:45+00:00jsing2026-01-17T06:31:45+00:00urn:sha1:650cf9e91c9b18210aaa53983bfb7725a344b7bb
gas dislikes bare .rodata - add .section before .rodata to make it happier
(LLVM does not care and is happy with either). For consistency, do the same
with .text.

Replace the perlasm generated SHA-256 assembly implementation with one that
is actually readable. Call the assembly implementation from a C wrapper
that can, in the future, dispatch to alternate implementations. Performance
is similar (or even better) on modern CPUs, while somewhat slower on older
CPUs (this is in part due to the wrapper, the impact of which is more
noticable with small block sizes).
Thanks to gkoehler@ and tb@ for testing.
