10# sha1_block procedure for x86_64.
11#
12# It was brought to my attention that on EM64T compiler-generated code
13# was far behind 32-bit assembler implementation. This is unlike on
14# Opteron where compiler-generated code was only 15% behind 32-bit
15# assembler, which originally made it hard to motivate the effort.
16# There was suggestion to mechanically translate 32-bit code, but I
17# dismissed it, reasoning that x86_64 offers enough register bank
18# capacity to fully utilize SHA-1 parallelism. Therefore this fresh
19# implementation:-) However! While 64-bit code does perform better
20# on Opteron, I failed to beat 32-bit assembler on EM64T core. Well,
21# x86_64 does offer larger *addressable* bank, but out-of-order core
22# reaches for even more registers through dynamic aliasing, and EM64T
23# core must have managed to run-time optimize even 32-bit code just as
24# good as 64-bit one. Performance improvement is summarized in the
25# following table:
26#
27# gcc 3.4 32-bit asm cycles/byte
28# Opteron +45% +20% 6.8
29# Xeon P4 +65% +0% 9.9
30# Core2 +60% +10% 7.0
31
32# August 2009.
33#
34# The code was revised to minimize code size and to maximize
35# "distance" between instructions producing input to 'lea'
36# instruction and the 'lea' instruction itself, which is essential
37# for Intel Atom core.
38
39# October 2010.
40#
41# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
42# is to offload message schedule denoted by Wt in NIST specification,
43# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module
44# for background and implementation details. The only difference from
45# 32-bit code is that 64-bit code doesn't have to spill @X[] elements
46# to free temporary registers.
47
48# April 2011.
49#
50# Add AVX code path. See sha1-586.pl for further information.
