# sha256/512_block procedure for x86_64.
#
# 40% improvement over compiler-generated code on Opteron. On EM64T
# sha256 was observed to run >80% faster and sha512 - >40%. No magical
# tricks, just straight implementation... I really wonder why gcc
# [being armed with inline assembler] fails to generate as fast code.
# The only thing which is cool about this module is that it's very
# same instruction sequence used for both SHA-256 and SHA-512. In
# former case the instructions operate on 32-bit operands, while in
# latter - on 64-bit ones. All I had to do is to get one flavor right,
# the other one passed the test right away:-)
#
# sha256_block runs in ~1005 cycles on Opteron, which gives you
# asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
# frequency in GHz. sha512_block runs in ~1275 cycles, which results
# in 128*1000/1275=100MBps per GHz. Is there room for improvement?
# Well, if you compare it to IA-64 implementation, which maintains
# X[16] in register bank[!], tends to 4 instructions per CPU clock
# cycle and runs in 1003 cycles, 1275 is very good result for 3-way
# issue Opteron pipeline and X[16] maintained in memory. So that *if*
# there is a way to improve it, *then* the only way would be to try to
# offload X[16] updates to SSE unit, but that would require "deeper"
# loop unroll, which in turn would naturally cause size blow-up, not
# to mention increased complexity! And once again, only *if* it's
# actually possible to noticeably improve overall ILP, instruction
# level parallelism, on a given CPU implementation in this case.
#
# Special note on Intel EM64T. While Opteron CPU exhibits perfect
# performance ratio of 1.5 between 64- and 32-bit flavors [see above],
# [currently available] EM64T CPUs apparently are far from it. On the
# contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
# sha256_block:-( This is presumably because 64-bit shifts/rotates
# apparently are not atomic instructions, but implemented in microcode.
#
# May 2012.
#
# Optimization including one of Pavel Semjanov's ideas, alternative
# Maj, resulted in >=5% improvement on most CPUs, +20% SHA256 and
# unfortunately -2% SHA512 on P4 [which nobody should care about
# that much].
#
# June 2012.
#
# Add SIMD code paths, see below for improvement coefficients. SSSE3
# code path was not attempted for SHA512, because improvement is not
# estimated to be high enough, noticeably less than 9%, to justify
# the effort, not on pre-AVX processors. [Obviously with exclusion
# for VIA Nano, but it has SHA512 instruction that is faster and
# should be used instead.] For reference, corresponding estimated
# upper limit for improvement for SSSE3 SHA256 is 28%. The fact that
# higher coefficients are observed on VIA Nano and Bulldozer has more
# to do with specifics of their architecture [which is topic for
# separate discussion].
#
# November 2012.
#
# Add AVX2 code path. Two consecutive input blocks are loaded to
# 256-bit %ymm registers, with data from first block to least
# significant 128-bit halves and data from second to most significant.
# The data is then processed with same SIMD instruction sequence as
# for AVX, but with %ymm as operands. Side effect is increased stack
# frame, 448 additional bytes in SHA256 and 1152 in SHA512, and 1.2KB
# code size increase.
#
# March 2014.
#
# Add support for Intel SHA Extensions.

# SHA256/512 for PowerISA v2.07.
#
# Accurate performance measurements are problematic, because it's
# always virtualized setup with possibly throttled processor.
# Relative comparison is therefore more informative. This module is
# ~60% faster than integer-only sha512-ppc.pl. To anchor to something
# else, SHA256 is 24% slower than sha1-ppc.pl and 2.5x slower than
# hardware-assisted aes-128-cbc encrypt. SHA512 is 20% faster than
# sha1-ppc.pl and 1.6x slower than aes-128-cbc. Another interesting
# result is degree of computational resources' utilization. POWER8 is
# "massively multi-threaded chip" and difference between single- and
# maximum multi-process benchmark results tells that utilization is
# whooping 94%. For sha512-ppc.pl we get [not unimpressive] 84% and
# for sha1-ppc.pl - 73%. 100% means that multi-process result equals
# to single-process one, given that all threads end up on the same
# physical core.

# whirlpool_block_mmx implementation.
#
*SCALE=\(2); # 2 or 8, that is the question:-) Value of 8 results
# in 16KB large table, which is tough on L1 cache, but eliminates
# unaligned references to it. Value of 2 results in 4KB table, but
# 7/8 of references to it are unaligned. AMD cores seem to be
# allergic to the latter, while Intel ones - to former [see the
# table]. I stick to value of 2 for two reasons: 1. smaller table
# minimizes cache trashing and thus mitigates the hazard of side-
# channel leakage similar to AES cache-timing one; 2. performance
# gap among different Âµ-archs is smaller.
#
# Performance table lists rounded amounts of CPU cycles spent by
# whirlpool_block_mmx routine on single 64 byte input block, i.e.
# smaller is better and asymptotic throughput can be estimated by
# multiplying 64 by CPU clock frequency and dividing by relevant
# value from the given table:
#
#		$SCALE=2/8	icc8	gcc3
# Intel P4	3200/4600	4600(*)	6400
# Intel PIII	2900/3000	4900	5400
# AMD K[78]	2500/1800	9900	8200(**)
#
# (*)	I've sketched even non-MMX assembler, but for the record
#	I've failed to beat the Intel compiler on P4, without using
#	MMX that is...
# (**)	... on AMD on the other hand non-MMX assembler was observed
#	to perform significantly better, but I figured this MMX
#	implementation is even faster anyway, so why bother? As for
#	pre-MMX AMD core[s], the improvement coefficient is more
#	than likely to vary anyway and I don't know how. But the
#	least I know is that gcc-generated code compiled with
#	-DL_ENDIAN and -DOPENSSL_SMALL_FOOTPRINT [see C module for
#	details] and optimized for Pentium was observed to perform
#	*better* on Pentium 100 than unrolled non-MMX assembler
#	loop... So we just say that I don't know if maintaining
#	non-MMX implementation would actually pay off, but till
#	opposite is proved "unlikely" is assumed.
