The easiest +way to accomplish this is to change 'shift' to be const in scale (as it +is in the transform routine above), and convert both routines to be +inline. This way, GCC can coerce the values to literals. + +Tested on a 970 (Apple G5) and POWER9 (Talos II); passed fate and played +a clip of Big Buck Bunny correctly. + +Signed-off-by: A.
