From 7cb9353de38461c6492712b7b43ee69c57921705 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 28 Feb 2018 06:42:53 +0000 Subject: [PATCH] r600/shader: when using images always load thread id gpr at start (v2) The delayed loading code was fail if we had control flow. This fixes: tests/spec/arb_shader_image_load_store/execution/image_checkerboard.shader_test v2: don't use temp_reg before setting temp_reg up.
