From 59003f3447c95793e7e66e0e34b362d3ce9958eb Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Sat, 19 Nov 2016 20:04:34 -0800 Subject: [PATCH] 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.
