From ef9cc7d0c176669c03130abf576f2b700be39514 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 7 Mar 2015 23:01:07 -0800 Subject: [PATCH] i965/fs: Set force_writemask_all on shader_time instructions. These computations don't have anything to do with the currently executing channels, so they should use force_writemask_all. This fixes assert failures.
