From d0990db6bd7d6e9e1cd780dc6b50ce00408a3cbc Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sat, 11 Dec 2010 13:22:19 +0100 Subject: r300/compiler: fix swizzle lowering with a presubtract source operand If a source operand has a non-native swizzle (e.g. the KIL instruction cannot have a swizzle other than .xyzw), the lowering pass uses one or more MOV instructions to move the operand to an intermediate temporary with native swizzles. This commit fixes that the presubtract information was lost during the lowering. NOTE: This is a candidate for both the 7.9 and 7.10 branches. --- src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c | 1 + 1 file changed, 1 insertion(+) (limited to 'src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c') diff --git a/src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c b/src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c index a0f7bd8174..133a9f72ec 100644 --- a/src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c +++ b/src/mesa/drivers/dri/r300/compiler/radeon_dataflow_swizzles.c @@ -56,6 +56,7 @@ static void rewrite_source(struct radeon_compiler * c, mov->U.I.DstReg.Index = tempreg; mov->U.I.DstReg.WriteMask = split.Phase[phase]; mov->U.I.SrcReg[0] = inst->U.I.SrcReg[src]; + mov->U.I.PreSub = inst->U.I.PreSub; phase_refmask = 0; for(unsigned int chan = 0; chan < 4; ++chan) { -- cgit v1.2.3
