# [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.

|

#
|
||
|
# 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...

# The SSSE3 implementation.
|
||
|
#
|
||
|
# %xmm[0-7] are used as ring @X[] buffer containing quadruples of last
|
||
|
# 32 elements of the message schedule or Xupdate outputs. First 4
|
||
|
# quadruples are simply byte-swapped input, next 4 are calculated
|
||
|
# according to method originally suggested by Dean Gaudet (modulo
|
||
|
# being implemented in SSSE3). Once 8 quadruples or 32 elements are
|
||
|
# collected, it switches to routine proposed by Max Locktyukhin.
|
||
|
#
|
||
|
# Calculations inevitably require temporary reqisters, and there are
|
||
|
# no %xmm registers left to spare. For this reason part of the ring
|
||
|
# buffer, X[2..4] to be specific, is offloaded to 3 quadriples ring
|
||

# buffer on the stack. Keep in mind that X[2] is alias X[-6], X[3] -
|
||
|
# X[-5], and X[4] - X[-4]...

# aiming to minimize amount of 9-byte instructions...
