17 # sha1_block procedure for x86_64.
18 #
19 # It was brought to my attention that on EM64T compiler-generated code
20 # was far behind 32-bit assembler implementation. This is unlike on
21 # Opteron where compiler-generated code was only 15% behind 32-bit
22 # assembler, which originally made it hard to motivate the effort.
23 # There was suggestion to mechanically translate 32-bit code, but I
24 # dismissed it, reasoning that x86_64 offers enough register bank
25 # capacity to fully utilize SHA-1 parallelism. Therefore this fresh
26 # implementation:-) However! While 64-bit code does perform better
27 # on Opteron, I failed to beat 32-bit assembler on EM64T core. Well,
28 # x86_64 does offer larger *addressable* bank, but out-of-order core
29 # reaches for even more registers through dynamic aliasing, and EM64T
30 # core must have managed to run-time optimize even 32-bit code just as
31 # good as 64-bit one. Performance improvement is summarized in the
32 # following table:
33 #
34 # gcc 3.4 32-bit asm cycles/byte
35 # Opteron +45% +20% 6.8
36 # Xeon P4 +65% +0% 9.9
37 # Core2 +60% +10% 7.0
38
39 # August 2009.
40 #
41 # The code was revised to minimize code size and to maximize
42 # "distance" between instructions producing input to 'lea'
43 # instruction and the 'lea' instruction itself, which is essential
44 # for Intel Atom core.
45
46 # October 2010.
47 #
48 # Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
49 # is to offload message schedule denoted by Wt in NIST specification,
50 # or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module
51 # for background and implementation details. The only difference from
52 # 32-bit code is that 64-bit code doesn't have to spill @X[] elements
53 # to free temporary registers.
54
55 # April 2011.
56 #
57 # Add AVX code path. See sha1-586.pl for further information.
58
59 # May 2013.
60 #
61 # Add AVX2+BMI code path. Initial attempt (utilizing BMI instructions
62 # and loading pair of consecutive blocks to 256-bit %ymm registers)
63 # did not provide impressive performance improvement till a crucial
64 # hint regarding the number of Xupdate iterations to pre-compute in
65 # advance was provided by Ilya Albrekht of Intel Corp.
66
67 # March 2014.
68 #
69 # Add support for Intel SHA Extensions.
