It's not really a power management or a sales decision either way, it's just what was easiest to build at the time. Our Mesa builds already include 586+ assembly for many routines, selected at runtime by processor inspection. I don't think they're using anything newer than SSE2 yet, there might be something to be gained from the newer ISA extensions. Patches gratefully accepted. If you want to see if there's any benefit from an i686 Mesa build just check it out from CVS and make local. Last time I looked the difference was down in the noise region. - ajax -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
