What speedup do you get? I'd have thought that in both cases (mesa and kernel) that the biggest gains are already done explicitly, with things like 3dnow and fast_copy/clear_page? Have you tried gcc-3's --march=athlon? (which as an aside intrigued me, is MESA_NO_3DNOW required to run veiwperf 'legally'? What exactly is cheating about such general purpose optimisations like mcpu=k6?) -- Michael. _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
