From: Hui Qi Tay Date: Tue, 28 Sep 2010 16:52:14 +0000 (+0100) Subject: draw: added viewport and cliptest flags X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3744d1c7d30543520cede8a6c580f26985978953;p=mesa.git draw: added viewport and cliptest flags Corrections in store_clip to store clip coordinates in AoS form. Viewport & cliptest flag options based on variant key. Put back draw_pt_post_vs and now 2 paths based on whether clipping occurs or not. --- diff --git a/src/gallium/auxiliary/draw/draw_llvm.c b/src/gallium/auxiliary/draw/draw_llvm.c index 36254d359c4..940b2d7ae55 100644 --- a/src/gallium/auxiliary/draw/draw_llvm.c +++ b/src/gallium/auxiliary/draw/draw_llvm.c @@ -736,10 +736,10 @@ store_clip(LLVMBuilderRef builder, indices[0] = LLVMConstInt(LLVMInt32Type(), 0, 0);
