From 398428f40684addd0a1465cf268436e8b1865351 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 24 Jun 2016 00:09:00 -0700 Subject: [PATCH] glsl: Fix location bias for patch variables. We need to subtract VARYING_SLOT_PATCH0, not VARYING_SLOT_VAR0. Since "patch" only applies to inputs and outputs, we can just handle this once outside the switch statement, rather than replicating the check twice and complicating the earlier conditions.
