From d548fa882b865b8e5052954b872e392312c38ab8 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 25 Oct 2016 06:53:03 +1000 Subject: [PATCH] radv/ac/llvm: trim texture return values The intrinsic engine asserts in llvm due to this, as we put a vec4 into a vec1, and the next instruction isn't expecting it. So trim the vector at the end before inserting it.
