About ~5% slower, probably because I was tuning for sandy-bridge and
introduced more FPU<=>CPU register moves.
Here's new version of patch, with FPU<=>CPU moves from original
implementation.
(Note: also changes encryption function to inline all code in to main
function, decryption still places common code to separate function to
reduce object size. This is to measure the difference.)
Yep, looks better than the previous run and also a bit better or on par
with the initial run I did.
Thanks again. Speed gained with patch is ~8%, and is able of getting
twofish-avx pass twofish-3way.
The thing is, I'm not sure whether optimizing the thing for each uarch
is a workable solution software-wise or maybe having a single version
which performs sufficiently ok on all uarches is easier/better to
maintain without causing code bloat. Hmmm...
Agreed, testing on multiple CPUs to get single well working version is
what I have done in the past. But purchasing all the latest CPUs on
the market isn't option for me, and for testing AVX I'm stuck with
sandy-bridge :)
