From 1ec7227d44dceae8de7b93f846bbd33d66007909 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Fri, 21 Oct 2016 17:43:00 +0200 Subject: nvc0/ir: fix emission of SHLADD with NEG modifiers This affects GF100:GK110 chipsets, but not GM107+ where the logic is a bit different. The emitters tried to emit sub instead of subr when src0 has a NEG modifier. This fixes the following piglit tests glsl-fs-loop-nested and glsl-vs-loop-nested.
