10# SHA512 block transform for x86. September 2007.
11#
12# Performance in clock cycles per processed byte (less is better):
13#
14#		Pentium	PIII	P4	AMD K8	Core2
15# gcc		100	75	116	54	66
16# icc		97	77	95	55	57
17# x86 asm	61	56	82	36	40
18# SSE2 asm	-	-	38	24	20
19# x86_64 asm(*)	-	-	30	10.0	10.5
20#
21# (*) x86_64 assembler performance is presented for reference
22#     purposes.
23#
24# IALU code-path is optimized for elder Pentiums. On vanilla Pentium
25# performance improvement over compiler generated code reaches ~60%,
26# while on PIII - ~35%. On newer �-archs improvement varies from 15%
27# to 50%, but it's less important as they are expected to execute SSE2
28# code-path, which is commonly ~2-3x faster [than compiler generated
29# code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
30# though it does not use 128-bit operations. The latter means that
31# SSE2-aware kernel is no longer required to execute the code. Another
32# difference is that new code optimizes amount of writes, but at the
33# cost of increased data cache "footprint" by 1/2KB.
