From 73ff4c5f70286ffe72ce6a60b68a8274d7425478 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 3 Sep 2014 19:45:19 -0400 Subject: [PATCH] freedreno/ir3: fix error in bail logic all_delayed will also be true if we didn't attempt to schedule anything due to no more instructions using current addr/pred. We rely on coming in to block_sched_undelayed() to detect and clean up when there are no more uses of the current addr/pred, which isn't necessarily an error. This fixes a regression introduced in b823abed.
