From 9793fc1335f11b4131d6db680bec567dcfccfb5f Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Fri, 15 Nov 2013 11:09:47 -0800 Subject: [PATCH] i965/fs: Use source's original type in register_coalesce(). Previously, register_coalesce() would modify mov vgrf1:f vgrf2:f cmp null vgrf3:d vgrf1:d to be cmp null vgrf3:d vgrf2:f and incorrectly use vgrf2's type in the instruction that the mov was coalesced into.
