# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
# project. The module is, however, dual licensed under OpenSSL and
# CRYPTOGAMS licenses depending on where you obtain it. For further
# details see http://www.openssl.org/~appro/cryptogams/.

#
# 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# assembler, which originally made it hard to motivate the effort.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.
