From 4d57e543b8e3bc0c5e0e6ced1f0d171a2cab3b8c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 27 Jun 2018 18:25:17 -0700 Subject: [PATCH] anv/pipeline: Fix up deref modes if we delete a FS output With the new deref instructions, we have to keep the modes consistent between the derefs and the variables they reference. Since we remove outputs by changing them to local variables, we need to run the fixup pass to fix the modes.
