Top quoting is bad, m'kay. But, I think it is doing what he thinks since he increases costs for ENDIF and decreases costs for IF. That is, it's backwards from DO/WHILE. Why this is a good thing to do... I don't know. I'd expect some data along with this patch in order to evaluate it properly. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
