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

# $output is the last argument if it looks like a file (it has an extension)
# $flavour is the first argument if it doesn't look like a file
