Author: Ilia Mirkin <[email protected]> Date: Wed Jul 1 18:22:23 2015 -0400 mesa/prog: relative offsets into constbufs are not constant The optimization logic relies on being able to read out constbuf values from program parameters. However that only works if there's no relative addressing involved.
