# sha1_block procedure for x86_64.
|
|
#
|
|
# It was brought to my attention that on EM64T compiler-generated code
|
|
# was far behind 32-bit assembler implementation. This is unlike on
|
|
# Opteron where compiler-generated code was only 15% behind 32-bit
|
|
# assembler, which originally made it hard to motivate the effort.
|
|
# There was suggestion to mechanically translate 32-bit code, but I
|
|
# dismissed it, reasoning that x86_64 offers enough register bank
|
|
# capacity to fully utilize SHA-1 parallelism. Therefore this fresh
|
|
# implementation:-) However! While 64-bit code does perform better
|
|
# on Opteron, I failed to beat 32-bit assembler on EM64T core. Well,
|
|
# x86_64 does offer larger *addressable* bank, but out-of-order core
|
|
# reaches for even more registers through dynamic aliasing, and EM64T
|
|
# core must have managed to run-time optimize even 32-bit code just as
|
|
# good as 64-bit one. Performance improvement is summarized in the
|
|
# following table:
|
|
#
|
|
# gcc 3.4 32-bit asm cycles/byte
|
|
# Opteron +45% +20% 6.8
|
|
# Xeon P4 +65% +0% 9.9
|
|
# Core2 +60% +10% 7.0
|
|
|
|
# August 2009.
|
|
#
|
|
# The code was revised to minimize code size and to maximize
|
|
# "distance" between instructions producing input to 'lea'
|
|
# instruction and the 'lea' instruction itself, which is essential
|
|
# for Intel Atom core.
|
|
|
|
# October 2010.
|
|
#
|
|
# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
|
|
# is to offload message schedule denoted by Wt in NIST specification,
|
|
# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module
|
|
# for background and implementation details. The only difference from
|
|
# 32-bit code is that 64-bit code doesn't have to spill @X[] elements
|
|
# to free temporary registers.
|
|
|
|
# April 2011.
|
|
#
|
|
# Add AVX code path. See sha1-586.pl for further information.
