# 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 µ-archs, but
|
||||
# it's 5 times smaller and optimizies 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...

# Add AMD XOP-specific code path, >30% improvement on Bulldozer over
|
||||
# May version, >60% over original. Add AVX+shrd code path, >25%
