You have to hack the driver up to do a round of copy-propagation at some point in the compilation flow before the first alu_to_scalar. If you do that, the patch above will trigger the bug and passes with my patch. Without such a driver hack (or doing it in Vulkan we we do copy-prop before the main optimization loop), it's nearly impossible to hit. --Jason
