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 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... +# +# 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.)
