This is unlike on 14 # Opteron where compiler-generated code was only 15% behind 32-bit 15 # assembler, which originally made it hard to motivate the effort. 16 # There was suggestion to mechanically translate 32-bit code, but I 17 # dismissed it, reasoning that x86_64 offers enough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. 51 52 ###################################################################### 53 # Current performance is summarized in following table.
