-# 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-# assembler, which originally made it hard to motivate the effort.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 performs 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
