You might add a sentence here that explains that this patch lets the driver avoid generating a bunch of MOVs that would otherwise be optimized away. The contrasting "avoid tons of MOVs" and "No changes in shader-db" might be confusing otherwise. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
