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

-# Written by Andy Polyakov <appro@openssl.org> 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/.

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

-# June 2011

-# This is AESNI-CBC+SHA1 "stitch" implementation. The idea, as spelled

-# in http://download.intel.com/design/intarch/papers/323686.pdf, is

-# that since AESNI-CBC encrypt exhibit *very* low instruction-level

-# parallelism, interleaving it with another algorithm would allow to

-# utilize processor resources better and achieve better performance.

-# SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and

-# AESNI code is weaved into it. Below are performance numbers in

-# cycles per processed byte, less is better, for standalone AESNI-CBC

-# encrypt, sum of the latter and standalone SHA1, and "stitched"

-# subroutine:

-# AES-128-CBC +SHA1 stitch gain

-# Westmere 3.77[+5.6] 9.37 6.65 +41%

-# Sandy Bridge 5.05[+5.2(6.3)] 10.25(11.35) 6.16(7.08) +67%(+60%)

-# AES-192-CBC

-# Westmere 4.51 10.11 6.97 +45%

-# Sandy Bridge 6.05 11.25(12.35) 6.34(7.27) +77%(+70%)

-# AES-256-CBC

-# Westmere 5.25 10.85 7.25 +50%

-# Sandy Bridge 7.05 12.25(13.35) 7.06(7.70) +74%(+73%)

-# (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for

-# background information. Above numbers in parentheses are SSSE3

-# results collected on AVX-capable CPU, i.e. apply on OSes that

-# don't support AVX.

-# Needless to mention that it makes no sense to implement "stitched"

-# *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1

-# fully utilize parallelism, so stitching would not give any gain

-# anyway. Well, there might be some, e.g. because of better cache

-# locality... For reference, here are performance results for

-# standalone AESNI-CBC decrypt:

-# AES-128-CBC AES-192-CBC AES-256-CBC

-# Westmere 1.31 1.55 1.80

-# Sandy Bridge 0.93 1.06 1.22
