   9 # whirlpool_block for x86_64.
  10 #
  11 # 2500 cycles per 64-byte input block on AMD64, which is *identical*
  12 # to 32-bit MMX version executed on same CPU. So why did I bother?
  13 # Well, it's faster than gcc 3.3.2 generated code by over 50%, and
  14 # over 80% faster than PathScale 1.4, an "ambitious" commercial
  15 # compiler. Furthermore it surpasses gcc 3.4.3 by 170% and Sun Studio
  16 # 10 - by 360%[!]... What is it with x86_64 compilers? It's not the
  17 # first example when they fail to generate more optimal code, when
  18 # I believe they had *all* chances to...
  19 #
  20 # Note that register and stack frame layout are virtually identical
  21 # to 32-bit MMX version, except that %r8-15 are used instead of
  22 # %mm0-8. You can even notice that K[i] and S[i] are loaded to
  23 # %eax:%ebx as pair of 32-bit values and not as single 64-bit one.
  24 # This is done in order to avoid 64-bit shift penalties on Intel
  25 # EM64T core. Speaking of which! I bet it's possible to improve
  26 # Opteron performance by compressing the table to 2KB and replacing
  27 # unaligned references with complementary rotations [which would
  28 # incidentally replace lea instructions], but it would definitely
  29 # just "kill" EM64T, because it has only 1 shifter/rotator [against
  30 # 3 on Opteron] and which is *unacceptably* slow with 64-bit
  31 # operand.
