# SHA256 block transform for x86. September 2007.
#
# Performance improvement over compiler generated code varies from
# 10% to 40% [see below]. Not very impressive on some ยต-archs, but
# it's 5 times smaller and optimizes amount of writes.
#
# May 2012.
#
# Optimization including two of Pavel Semjanov's ideas, alternative
# Maj and full unroll, resulted in ~20-25% improvement on most CPUs,
# ~7% on Pentium, ~40% on Atom. As fully unrolled loop body is almost
# 15x larger, 8KB vs. 560B, it's fired only for longer inputs. But not
# on P4, where it kills performance, nor Sandy Bridge, where folded
# loop is approximately as fast...
#
# June 2012.
#
# Add AMD XOP-specific code path, >30% improvement on Bulldozer over
# May version, >60% over original. Add AVX+shrd code path, >25%
# improvement on Sandy Bridge over May version, 60% over original.
#
# May 2013.
#
# Replace AMD XOP code path with SSSE3 to cover more processors.
# (Biggest improvement coefficient is on upcoming Atom Silvermont,
# not shown.) Add AVX+BMI code path.
#
# March 2014.
#
# Add support for Intel SHA Extensions.
#
# Performance in clock cycles per processed byte (less is better):
