Well, I of course can change the SPEC code

         464.h264ref,      1271.00,        1879.00,        1.47



As for Dodji's patch: can someone attach it here? 

Let me benchmark it too, although if that's just optimizing within one BB

I don't expect more than 5% difference (based on my experiments in llvm). 



Dodji, what are your numbers?
