Hi,

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

http://www.linux.org.ru/news/hardware/7282032/page1#comment-7284811

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.
