1#!/usr/bin/env perl 2 3# ==================================================================== 4# [Re]written by Andy Polyakov <appro@openssl.org> for the OpenSSL 5# project. The module is, however, dual licensed under OpenSSL and 6# CRYPTOGAMS licenses depending on where you obtain it. For further 7# details see http://www.openssl.org/~appro/cryptogams/. 8# ==================================================================== 9 10# "[Re]written" was achieved in two major overhauls. In 2004 BODY_* 11# functions were re-implemented to address P4 performance issue [see 12# commentary below], and in 2006 the rest was rewritten in order to 13# gain freedom to liberate licensing terms. 14 15# January, September 2004. 16# 17# It was noted that Intel IA-32 C compiler generates code which 18# performs ~30% *faster* on P4 CPU than original *hand-coded* 19# SHA1 assembler implementation. To address this problem (and 20# prove that humans are still better than machines:-), the 21# original code was overhauled, which resulted in following 22# performance changes: 23# 24# compared with original compared with Intel cc 25# assembler impl. generated code 26# Pentium -16% +48% 27# PIII/AMD +8% +16% 28# P4 +85%(!) +45% 29# 30# As you can see Pentium came out as looser:-( Yet I reckoned that 31# improvement on P4 outweights the loss and incorporate this 32# re-tuned code to 0.9.7 and later. 33# ---------------------------------------------------------------- 34# <appro@fy.chalmers.se> 35 36# August 2009. 37# 38# George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as 39# '(c&d) + (b&(c^d))', which allows to accumulate partial results 40# and lighten "pressure" on scratch registers. This resulted in 41# >12% performance improvement on contemporary AMD cores (with no 42# degradation on other CPUs:-). Also, the code was revised to maximize 43# "distance" between instructions producing input to 'lea' instruction 44# and the 'lea' instruction itself, which is essential for Intel Atom 45# core and resulted in ~15% improvement. 46 47# October 2010. 48# 49# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it 50# is to offload message schedule denoted by Wt in NIST specification, 51# or Xupdate in OpenSSL source, to SIMD unit. The idea is not novel, 52# and in SSE2 context was first explored by Dean Gaudet in 2004, see 53# http://arctic.org/~dean/crypto/sha1.html. Since then several things 54# have changed that made it interesting again: 55# 56# a) XMM units became faster and wider; 57# b) instruction set became more versatile; 58# c) an important observation was made by Max Locktykhin, which made 59# it possible to reduce amount of instructions required to perform 60# the operation in question, for further details see 61# http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/. 62 63# April 2011. 64# 65# Add AVX code path, probably most controversial... The thing is that 66# switch to AVX alone improves performance by as little as 4% in 67# comparison to SSSE3 code path. But below result doesn't look like 68# 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as 69# pair of ��-ops, and it's the additional ��-ops, two per round, that 70# make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded 71# as single ��-op by Sandy Bridge and it's replacing 'ro[rl]' with 72# equivalent 'sh[rl]d' that is responsible for the impressive 5.1 73# cycles per processed byte. But 'sh[rl]d' is not something that used 74# to be fast, nor does it appear to be fast in upcoming Bulldozer 75# [according to its optimization manual]. Which is why AVX code path 76# is guarded by *both* AVX and synthetic bit denoting Intel CPUs. 77# One can argue that it's unfair to AMD, but without 'sh[rl]d' it 78# makes no sense to keep the AVX code path. If somebody feels that 79# strongly, it's probably more appropriate to discuss possibility of 80# using vector rotate XOP on AMD... 81 82# March 2014. 83# 84# Add support for Intel SHA Extensions. 85 86###################################################################### 87# Current performance is summarized in following table.

First 4 534# quadruples are simply byte-swapped input, next 4 are calculated 535# according to method originally suggested by Dean Gaudet (modulo 536# being implemented in SSSE3). Once 8 quadruples or 32 elements are 537# collected, it switches to routine proposed by Max Locktyukhin. 538# 539# Calculations inevitably require temporary reqisters, and there are 540# no %xmm registers left to spare.
