Do not propagate a copy if source and destination are identical. Otherwise code like MOV TEMP[0].xyzw, TEMP[0].wzyx MOV TEMP[1].xyzw, TEMP[0].xyzw is changed to MOV TEMP[0].xyzw, TEMP[0].wzyx MOV TEMP[1].xyzw, TEMP[0].wzyx This fixes Piglit test shaders/glsl-copy-propagation-self-2 for gallium drivers. NOTE: This is a candidate for the stable branches. Signed-off-by: Fabian Bieler <fabianbieler@fastmail.fm> Reviewed-by: Brian Paul <brianp@vmware.com> |
