From f7eb95a5269fab015df23dd7c5152418bbd10033 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 20 May 2016 16:29:44 -0700 Subject: [PATCH] nir: Fix crash in nir_lower_wpos_center(). Otherwise we rewrote the fadd to use itself, causing crashes in validation. Instead, start after the last use like we should. A brown paper bag fix. Fixes crashes in several Vulkan tests.
