# SHA512 block transform for x86. September 2007.

# May 2013.
#
# Add SSSE3 code path, 20-25% improvement [over original SSE2 code].
#
# Performance in clock cycles per processed byte (less is better):
#
# gcc icc x86 asm SIMD(*) x86_64(**)
# Pentium 100 97 61 - -
# PIII 75 77 56 - -
# P4 116 95 82 34.6 30.8
# AMD K8 54 55 36 20.7 9.57
# Core2 66 57 40 15.9 9.97

# (*) whichever best applicable.
# (**) x86_64 assembler performance is presented for reference
# purposes, the results are for integer-only code.
# (***) paddq is incredibly slow on Atom.
#
# 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 ยต-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.
