From 10ce6779e8a64c33add70e440f885c210f3fa6ee Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Wed, 11 Aug 2010 15:13:17 +0100 Subject: gallivm: Use lp_build_div instead of lp_build_mul + lp_build_rcp. Single divide, so let lp_build_div decide how to implement this. This will save a multiplication in architectures which don't have a RCP intrinsic. --- src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/gallium/auxiliary') diff --git a/src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c b/src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c index 665b010ecec..307506507de 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c +++ b/src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c @@ -1219,8 +1219,7 @@ lp_build_cube_ima(struct lp_build_context *coord_bld, LLVMValueRef coord) /* ima = -0.5 / abs(coord); */ LLVMValueRef negHalf = lp_build_const_vec(coord_bld->type, -0.5); LLVMValueRef absCoord = lp_build_abs(coord_bld, coord); - LLVMValueRef ima = lp_build_mul(coord_bld, negHalf, - lp_build_rcp(coord_bld, absCoord)); + LLVMValueRef ima = lp_build_div(coord_bld, negHalf, absCoord); return ima; } -- cgit v1.2.3
