9# sha256/512_block procedure for x86_64.
10#
11# 40% improvement over compiler-generated code on Opteron. On EM64T
12# sha256 was observed to run >80% faster and sha512 - >40%. No magical
13# tricks, just straight implementation... I really wonder why gcc
14# [being armed with inline assembler] fails to generate as fast code.
15# The only thing which is cool about this module is that it's very
16# same instruction sequence used for both SHA-256 and SHA-512. In
17# former case the instructions operate on 32-bit operands, while in
18# latter - on 64-bit ones. All I had to do is to get one flavor right,
19# the other one passed the test right away:-)
20#
21# sha256_block runs in ~1005 cycles on Opteron, which gives you
22# asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
23# frequency in GHz. sha512_block runs in ~1275 cycles, which results
24# in 128*1000/1275=100MBps per GHz. Is there room for improvement?
25# Well, if you compare it to IA-64 implementation, which maintains
26# X[16] in register bank[!], tends to 4 instructions per CPU clock
27# cycle and runs in 1003 cycles, 1275 is very good result for 3-way
28# issue Opteron pipeline and X[16] maintained in memory. So that *if*
29# there is a way to improve it, *then* the only way would be to try to
30# offload X[16] updates to SSE unit, but that would require "deeper"
31# loop unroll, which in turn would naturally cause size blow-up, not
32# to mention increased complexity! And once again, only *if* it's
33# actually possible to noticeably improve overall ILP, instruction
34# level parallelism, on a given CPU implementation in this case.
35#
36# Special note on Intel EM64T. While Opteron CPU exhibits perfect
37# perfromance ratio of 1.5 between 64- and 32-bit flavors [see above],
38# [currently available] EM64T CPUs apparently are far from it. On the
39# contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
40# sha256_block:-( This is presumably because 64-bit shifts/rotates
41# apparently are not atomic instructions, but implemented in microcode.
