I think the following instructions are predicated on the flag value set by this compare instruction -- a couple of shifts, and add, and then a while instruction. I don't see a break or another way out of the loop, so I'm guessing that the while is predicated on this compare. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
