From 26187f3890cd92d6871ffb431763b27cacd8d4fe Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 5 Jul 2016 10:26:14 +1000 Subject: [PATCH] st/glsl_to_tgsi: fix st_src_reg_for_double constant. This needs to set the src swizzle so it doesn't access the .zw members ever when we are just emitting a 0 constant here. This fixes: vert-conversion-explicit-dvec3-bvec3.shader_test and a bunch of other fp64 tests on softpipe and radeonsi.
