Bulldozer x264 optimisations

[Racer]

Hello,

as the bulldozer cpu is available now for a while it would be interesting if x264 could be speed up due to the new microarchitecture.
Or is it the fact that x264 can not benefit a of XOP, FMA ...

x264 already contains a number of XOP optimizations. See the changelog:

FMA only contains floating-point instructions and therefore is not useful for x264:

Actually I think x264 uses fma for the macroblock tree analysis too, but that probably has a minor effect.
