However I don't know when I get it sent to the ML because I can't finish piglit testing — GPU hangs. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

It's possible copy propagation might not always do what we need it too, and we also shouldn't depend on optimisations to do this type of thing for us. I'm not sure if the same is true for TGSI, but the following commit should re-enable packing for most cases in a safer way, so we just disable it everywhere. No change in shader-db for i965 (BDW) Acked-by: Elie Tournier Reviewed-by: Kenneth Graunke Reverting the commit fixes the problem. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
