From 7a83be4b28953c9dfc609ad084f57e671310661a Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 10 Feb 2018 10:24:14 +0000 Subject: [PATCH] gallium/llvmpipe: Fix compiler warnings about ddx/ddy/ddmax. My gcc doesn't figure out that dims >= 1 (seems reasonable), and doesn't notice that ddmax is used from the same no_rho_opt as its initialization.
