19# This is AESNI-CBC+SHA1 "stitch" implementation. The idea, as spelled
20# in http://download.intel.com/design/intarch/papers/323686.pdf, is
21# that since AESNI-CBC encrypt exhibit *very* low instruction-level
22# parallelism, interleaving it with another algorithm would allow to
23# utilize processor resources better and achieve better performance.
24# SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and
25# AESNI code is weaved into it. Below are performance numbers in
26# cycles per processed byte, less is better, for standalone AESNI-CBC
27# encrypt, sum of the latter and standalone SHA1, and "stitched"
28# subroutine:
29#
30# AES-128-CBC +SHA1 stitch gain
31# Westmere 3.77[+5.3] 9.07 6.55 +38%
32# Sandy Bridge 5.05[+5.0(6.1)] 10.06(11.15) 5.98(7.05) +68%(+58%)
33# Ivy Bridge 5.05[+4.6] 9.65 5.54 +74%

36# Bulldozer 5.77[+6.0] 11.72 6.37 +84%
37# Ryzen(**) 2.71[+1.93] 4.64 2.74 +69%
38# Goldmont(**) 3.82[+1.70] 5.52 4.20 +31%

45# Bulldozer 6.89 12.84 6.96 +84%
46#
47# AES-256-CBC
48# Westmere 5.25 10.55 7.21 +46%
49# Sandy Bridge 7.05 12.06(13.15) 7.12(7.72) +69%(+70%)
50# Ivy Bridge 7.05 11.65 7.12 +64%

54# Ryzen(**) 3.71 5.64 3.72 +52%
55# Goldmont(**) 5.35 7.05 5.76 +22%
56#
57# (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for
58# background information. Above numbers in parentheses are SSSE3
59# results collected on AVX-capable CPU, i.e. apply on OSes that
60# don't support AVX.
61# (**) SHAEXT results.
62#
63# Needless to mention that it makes no sense to implement "stitched"
64# *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1
65# fully utilize parallelism, so stitching would not give any gain
66# anyway. Well, there might be some, e.g. because of better cache
67# locality... For reference, here are performance results for
68# standalone AESNI-CBC decrypt:
69#
70# AES-128-CBC AES-192-CBC AES-256-CBC
71# Westmere 1.25 1.50 1.75
72# Sandy Bridge 0.74 0.91 1.09
73# Ivy Bridge 0.74 0.90 1.11
74# Haswell 0.63 0.76 0.88
75# Bulldozer 0.70 0.85 0.99
76
77# And indeed:
78#
79# AES-256-CBC +SHA1 stitch gain
80# Westmere 1.75 7.20 6.68 +7.8%
81# Sandy Bridge 1.09 6.09(7.22) 5.82(6.95) +4.6%(+3.9%)
82# Ivy Bridge 1.11 5.70 5.45 +4.6%
83# Haswell 0.88 4.45(5.00) 4.39(4.69) +1.4%(*)(+6.6%)
84# Bulldozer 0.99 6.95 5.95 +17%(**)
85#
86# (*) Tiny improvement coefficient on Haswell is because we compare
87# AVX1 stitch to sum with AVX2 SHA1.
88# (**) Execution is fully dominated by integer code sequence and
89# SIMD still hardly shows [in single-process benchmark;-]
