From f246aa6bcab57f85a143cbfe7e9de24237921249 Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Fri, 31 Jul 2015 14:36:30 +0200 Subject: [PATCH] i965/vec4: do not predicate scratch writes for BRW_OPCODE_SEL instructions The dst is always written, in this case the predicate is only used to select the value to write, so if we are spilling the dst we always want to write whatever value we selected to scratch.
