-# ====================================================================

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-# assembler, which originally made it hard to motivate the effort.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