I asked on the flatassember.net forums for a review of this code. See http://board.flatassembler.net/topic.php?t=10839#104485 As mentioned in the thread, what kind of performance difference do you have if you move the cache prefetch outside of the main loop and remove it elsewhere? Please check out the other suggestions. Thanks, Matt _______________________________________________ xorg-devel mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-devel
