From ec8cc65926de3e7391f3bcec8ee26fc8f4d36159 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 1 Jan 2013 15:09:26 -0800 Subject: i965/fs: Remove force_sechalf stack Only Gen4 color write setup uses the force_sechalf flag, and it only sets it on a single instruction. It also already has to get a pointer to the instruction and manually set the saturate flag, so we may as well just set force_sechalf the same way and avoid the complexity of a stack.
