They now generally conform to the following argument sequence:
script.pl "$(PERLASM_SCHEME)" [ C preprocessor arguments ... ] \
$(PROCESSOR) <output file>
However, in the spirit of being able to use these scripts manually,
they also allow for no argument, or for only the flavour, or for only
the output file. This is done by only using the last argument as
output file if it's a file (it has an extension), and only using the
first argument as flavour if it isn't a file (it doesn't have an
extension).
While we're at it, we make all $xlate calls the same, i.e. the $output
argument is always quoted, and we always die on error when trying to
start $xlate.
There's a perl lesson in this, regarding operator priority...
This will always succeed, even when it fails:
open FOO, "something" || die "ERR: $!";
The reason is that '||' has higher priority than list operators (a
function is essentially a list operator and gobbles up everything
following it that isn't lower priority), and since a non-empty string
is always true, so that ends up being exactly the same as:
open FOO, "something";
This, however, will fail if "something" can't be opened:
open FOO, "something" or die "ERR: $!";
The reason is that 'or' has lower priority that list operators,
i.e. it's performed after the 'open' call.

# Keccak-1600 for x86 MMX.
|
|
#
|
|
# June 2017.
|
|
#
|
|
# Below code is KECCAK_2X implementation (see sha/keccak1600.c) with
|
|
# C[5] held in register bank and D[5] offloaded to memory. Though
|
|
# instead of actually unrolling the loop pair-wise I simply flip
|
|
# pointers to T[][] and A[][] and the end of round. Since number of
|
|
# rounds is even, last round writes to A[][] and everything works out.
|
|
# It's argued that MMX is the only code path meaningful to implement
|
|
# for x86. This is because non-MMX-capable processors is an extinct
|
|
# breed, and they as well can lurk executing compiler-generated code.
|
|
# For reference gcc-5.x-generated KECCAK_2X code takes 89 cycles per
|
|
# processed byte on Pentium. Which is fair result. But older compilers
|
|
# produce worse code. On the other hand one can wonder why not 128-bit
|
|
# SSE2? Well, SSE2 won't provide double improvement, rather far from
|
|
# that, if any at all on some processors, because it will take extra
|
|
# permutations and inter-bank data trasfers. Besides, contemporary
|
|
# CPUs are better off executing 64-bit code, and it makes lesser sense
|
|
# to invest into fancy 32-bit code. And the decision doesn't seem to
|
|
# be inadequate, if one compares below results to "64-bit platforms in
|
|
# 32-bit mode" SIMD data points available at
|
|
# http://keccak.noekeon.org/sw_performance.html.
