  17 # SHA256 block transform for x86. September 2007.
  18 #
  19 # Performance improvement over compiler generated code varies from
  20 # 10% to 40% [see below]. Not very impressive on some µ-archs, but
  21 # it's 5 times smaller and optimizies amount of writes.
  22 #
  23 # May 2012.
  24 #
  25 # Optimization including two of Pavel Semjanov's ideas, alternative
  26 # Maj and full unroll, resulted in ~20-25% improvement on most CPUs,
  27 # ~7% on Pentium, ~40% on Atom. As fully unrolled loop body is almost
  28 # 15x larger, 8KB vs. 560B, it's fired only for longer inputs. But not
  29 # on P4, where it kills performance, nor Sandy Bridge, where folded
  30 # loop is approximately as fast...
  31 #
  32 # June 2012.
  33 #
  34 # Add AMD XOP-specific code path, >30% improvement on Bulldozer over
  35 # May version, >60% over original. Add AVX+shrd code path, >25%
  36 # improvement on Sandy Bridge over May version, 60% over original.
  37 #
  38 # May 2013.
  39 #
  40 # Replace AMD XOP code path with SSSE3 to cover more processors.
  41 # (Biggest improvement coefficient is on upcoming Atom Silvermont,
  42 # not shown.) Add AVX+BMI code path.
  43 #
  44 # March 2014.
  45 #
  46 # Add support for Intel SHA Extensions.
  47 #
