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| # assembler, which originally made it hard to motivate the effort.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