lib/libcrypto/sha: sha256_amd64.c sha256_amd64_generic.S
Log message:
Provide a replacement assembly implementation for SHA-256 on amd64.
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.
