From 48de40ce9c45de154965490843f9e50407970c26 Mon Sep 17 00:00:00 2001 From: Boyan Ding Date: Wed, 26 Aug 2015 19:52:50 +0800 Subject: [PATCH] vc4: Initialize pack field of qreg to 0 in qir_get_temp This avoids generation of undefined packing in qir and qpu instructions, fixing a lot of rendering errors. Fixes 8b36d107fdd (vc4: Pack the unorm-packing bits into a src MUL instruction when possible.)
