From 88ea960aa74402ea358d05b95709c3299002ad83 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 18 May 2016 09:31:49 -0700 Subject: [PATCH] nir: Make nir_lower_wpos_ytransform() match FragCoord by location. gl_FragCoord is a shader input with location == VARYING_SLOT_POS. ARB_fragment_programs have an equivalent input at VARYING_SLOT_POS, but it isn't called gl_FragCoord. We do want to transform it. Matching by location guarantees we catch both. Fixes several fp tests on a branch which uses this pass on i965.
