Author: Matt Turner <[email protected]> Date: Sat Nov 19 20:04:34 2016 -0800 i965/vec4: Use UW-typed operands when dest is UW. Using a UD-typed operand makes the execution size D, and if the size of the execution type is greater than the size of the destination type, the destination must be appropriately strided. We actually just want UW-types all around.
