Subject: Re: testing -xop targets


We got first benchmarks of JtR's -xop builds on Bulldozer:

XOP is actually faster than AVX (due to the smaller DES S-box gate
count), but both are slower than Sandy Bridge's AVX.

Also, 256-bit XOP and AVX is very slow on Bulldozer.  I need to update
the 32-bit -xop target to use 128-bit XOP instead.
