the MMX registers seem to be a good place for optimizing a chess program. Is anyone using these for quick ANDs or ORs? Or is the lack of useful MMX instructions too inhibiting? the only place I can see a gain by processing many bitboards at once would be in attacks() by generating rank,file,and diags all at once in the MM registers, but i might just end up needing more instructions for the MMX operations Anyone trying this?
