This is unlike on 14# Opteron where compiler-generated code was only 15% behind 32-bit 15# assembler, which originally made it hard to motivate the effort. 16# There was suggestion to mechanically translate 32-bit code, but I 17# dismissed it, reasoning that x86_64 offers enough register bank 18# capacity to fully utilize SHA-1 parallelism. Therefore this fresh 19# implementation:-) However! While 64-bit code does perform better 20# on Opteron, I failed to beat 32-bit assembler on EM64T core. Well, 21# x86_64 does offer larger *addressable* bank, but out-of-order core 22# reaches for even more registers through dynamic aliasing, and EM64T 23# core must have managed to run-time optimize even 32-bit code just as 24# good as 64-bit one. Performance improvement is summarized in the 25# following table: 26# 27# gcc 3.4 32-bit asm cycles/byte 28# Opteron +45% +20% 6.8 29# Xeon P4 +65% +0% 9.9 30# Core2 +60% +10% 7.0 31 32# August 2009. 33# 34# The code was revised to minimize code size and to maximize 35# "distance" between instructions producing input to 'lea' 36# instruction and the 'lea' instruction itself, which is essential 37# for Intel Atom core. 38 39# October 2010. 40# 41# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it 42# is to offload message schedule denoted by Wt in NIST specification, 43# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module 44# for background and implementation details. The only difference from 45# 32-bit code is that 64-bit code doesn't have to spill @X[] elements 46# to free temporary registers. 47 48# April 2011. 49# 50# Add AVX code path. See sha1-586.pl for further information. 51 52# May 2013. 53# 54# Add AVX2+BMI code path. Initial attempt (utilizing BMI instructions 55# and loading pair of consecutive blocks to 256-bit %ymm registers) 56# did not provide impressive performance improvement till a crucial 57# hint regarding the number of Xupdate iterations to pre-compute in 58# advance was provided by Ilya Albrekht of Intel Corp. 59 60# March 2014. 61# 62# Add support for Intel SHA Extensions. 63 64###################################################################### 65# Current performance is summarized in following table.
