From a1a6f007823f203755fb54a1f3b7f53ae6cbfef0 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sun, 5 Jul 2015 19:53:10 -0400 Subject: [PATCH] freedreno/ir3/ra: fix failed assert for a0/p0 The address and predicate register are special, they don't get assigned in RA. So do a better job of ignoring them rather than hitting later asserts.
