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

-# [Re]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/.

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

-# "[Re]written" was achieved in two major overhauls. In 2004 BODY_*

-# functions were re-implemented to address P4 performance issue [see

-# commentary below], and in 2006 the rest was rewritten in order to

-# gain freedom to liberate licensing terms.

-# January, September 2004.

-# It was noted that Intel IA-32 C compiler generates code which

-# performs ~30% *faster* on P4 CPU than original *hand-coded*

-# SHA1 assembler implementation. To address this problem (and

-# prove that humans are still better than machines:-), the

-# original code was overhauled, which resulted in following

-# performance changes:

-# compared with original compared with Intel cc

-# assembler impl. generated code

-# Pentium -16% +48%

-# PIII/AMD +8% +16%

-# P4 +85%(!) +45%

-# As you can see Pentium came out as looser:-( Yet I reckoned that

-# improvement on P4 outweights the loss and incorporate this

-# re-tuned code to 0.9.7 and later.

-# ----------------------------------------------------------------

-# <appro@fy.chalmers.se>

-# August 2009.

-# George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as

-# '(c&d) + (b&(c^d))', which allows to accumulate partial results

-# and lighten "pressure" on scratch registers. This resulted in

-# >12% performance improvement on contemporary AMD cores (with no

-# degradation on other CPUs:-). Also, the code was revised to maximize

-# "distance" between instructions producing input to 'lea' instruction

-# and the 'lea' instruction itself, which is essential for Intel Atom

-# core and resulted in ~15% improvement.

-# 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. The idea is not novel,

-# and in SSE2 context was first explored by Dean Gaudet in 2004, see

-# http://arctic.org/~dean/crypto/sha1.html. Since then several things

-# have changed that made it interesting again:

-# a) XMM units became faster and wider;

-# b) instruction set became more versatile;

-# c) an important observation was made by Max Locktykhin, which made

-# it possible to reduce amount of instructions required to perform

-# the operation in question, for further details see

-# http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/.

-# April 2011.

-# Add AVX code path, probably most controversial... The thing is that

-# switch to AVX alone improves performance by as little as 4% in

-# comparison to SSSE3 code path. But below result doesn't look like

-# 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as

-# pair of µ-ops, and it's the additional µ-ops, two per round, that

-# make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded

-# as single µ-op by Sandy Bridge and it's replacing 'ro[rl]' with

-# equivalent 'sh[rl]d' that is responsible for the impressive 5.1

-# cycles per processed byte. But 'sh[rl]d' is not something that used

-# to be fast, nor does it appear to be fast in upcoming Bulldozer

-# [according to its optimization manual]. Which is why AVX code path

-# is guarded by *both* AVX and synthetic bit denoting Intel CPUs.

-# One can argue that it's unfair to AMD, but without 'sh[rl]d' it

-# makes no sense to keep the AVX code path. If somebody feels that

-# strongly, it's probably more appropriate to discuss possibility of

-# using vector rotate XOP on AMD...

-# SSE instruction sequence is first broken to groups of indepentent

-# instructions, independent in respect to their inputs and shifter

-# (not all architectures have more than one). Then IALU instructions

-# are "knitted in" between the SSE groups. Distance is maintained for

-# SSE latency of 2 in hope that it fits better upcoming AMD Bulldozer

-# [which allegedly also implements SSSE3]...

-# Temporary registers usage. X[2] is volatile at the entry and at the

-# end is restored from backtrace ring buffer. X[3] is expected to

-# contain current K_XX_XX constant and is used to caclulate X[-1]+K

-# from previous round, it becomes volatile the moment the value is

-# saved to stack for transfer to IALU. X[4] becomes volatile whenever

-# X[-4] is accumulated and offloaded to backtrace ring buffer, at the

-# end it is loaded with next K_XX_XX [which becomes X[3] in next

-# round]...
