| 17 | # sha1_block procedure for x86_64. |

| 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| 22 | # assembler, which originally made it hard to motivate the effort.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. |
