* ====================================================================
*
* 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
* performance 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
* apparently are not atomic instructions, but implemented in microcode.

* This source originates from OpenSSL file sha512-x86_64.pl at
* ftp://ftp.openssl.org/snapshot/openssl-0.9.8-stable-SNAP-20080131.tar.gz
* (presumably for future OpenSSL release 0.9.8h), with these changes:
*
* 1. Added perl "use strict" and declared variables.
*
* 2. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
* /usr/include/sys/asm_linkage.h, .ident keywords, and lint(1B) guards.
*
* 3. Removed x86_64-xlate.pl script (not needed for as(1) or gas(1)
* assemblers). Replaced the .picmeup macro with assembler code.
*
* 4. Added 8 to $ctx, as OpenSolaris OS has an extra 4-byte field, "algotype",
* at the beginning of SHA2_CTX (the next field is 8-byte aligned).
