# SHA512 block transform for x86. September 2007.

#
# IALU code-path is optimized for elder Pentiums. On vanilla Pentium
# performance improvement over compiler generated code reaches ~60%,
# while on PIII - ~35%. On newer µ-archs improvement varies from 15%
# to 50%, but it's less important as they are expected to execute SSE2
# code-path, which is commonly ~2-3x faster [than compiler generated
# code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
# though it does not use 128-bit operations. The latter means that
# SSE2-aware kernel is no longer required to execute the code. Another
# difference is that new code optimizes amount of writes, but at the
# cost of increased data cache "footprint" by 1/2KB.
