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+# assembler, which originally made it hard to motivate the effort.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

+# sha256/512_block procedure for x86_64.
+#
+# 40% improvement over compiler-generated code on Opteron. On EM64T
+# sha256 was observed to run >80% faster and sha512 - >40%. No magical
+# tricks, just straight implementation... I really wonder why gcc
+# [being armed with inline assembler] fails to generate as fast code.
+# The only thing which is cool about this module is that it's very
+# same instruction sequence used for both SHA-256 and SHA-512. In
+# former case the instructions operate on 32-bit operands, while in
+# latter - on 64-bit ones. All I had to do is to get one flavor right,
+# the other one passed the test right away:-)
+#
+# sha256_block runs in ~1005 cycles on Opteron, which gives you
+# asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
+# frequency in GHz. sha512_block runs in ~1275 cycles, which results
+# in 128*1000/1275=100MBps per GHz. Is there room for improvement?
+# Well, if you compare it to IA-64 implementation, which maintains
+# X[16] in register bank[!], tends to 4 instructions per CPU clock
+# cycle and runs in 1003 cycles, 1275 is very good result for 3-way
+# issue Opteron pipeline and X[16] maintained in memory. So that *if*
+# there is a way to improve it, *then* the only way would be to try to
+# offload X[16] updates to SSE unit, but that would require "deeper"
+# loop unroll, which in turn would naturally cause size blow-up, not
+# to mention increased complexity! And once again, only *if* it's
+# actually possible to noticeably improve overall ILP, instruction
+# level parallelism, on a given CPU implementation in this case.
+#
+# Special note on Intel EM64T. While Opteron CPU exhibits perfect
+# perfromance ratio of 1.5 between 64- and 32-bit flavors [see above],
+# [currently available] EM64T CPUs apparently are far from it. On the
+# contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
+# sha256_block:-( This is presumably because 64-bit shifts/rotates
