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+# assembler, which originally made it hard to motivate the effort.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