keccak1600-ppc64.pl keccak1600p8-ppc.pl
Log Message:
Revert the conditional use of vsx on keccak. Upstream wants to disable it
instead (dot-asm:
So that both assembly modules export SHA3_absorb_vsx... Either way,
it makes lesser sense to deploy vector keccak1600p8-ppc.pl, because
benefits are not that clear. It's only nominally faster than scalar
module on POWER8 but significantly slower on POWER9. Because POWER9
is better equipped to handle non-vector code. On related note,
there is version optimized for little-endian, as well as 32-bit
version. [And since MIPS was mentioned, there is even MIPS module...]
