This delays the waitcnt for has_attr_ring_wait_bug by a few instructions. fossil-db (gfx1201): Totals from 9 (0.00% of 208640) affected shaders: Instrs: 19352 -> 19506 (+0.80%) CodeSize: 101180 -> 101716 (+0.53%) Latency: 660221 -> 678782 (+2.81%); split: -0.00%, +2.81% InvThroughput: 95106 -> 97398 (+2.41%) fossil-db (navi33): Totals from 58834 (28.20% of 208626) affected shaders: Instrs: 22424304 -> 22424571 (+0.00%) CodeSize: 110198112 -> 110199184 (+0.00%) Latency: 115894319 -> 126491124 (+9.14%); split: -0.00%, +9.14% InvThroughput: 19424631 -> 19754358 (+1.70%); split: -0.00%, +1.70% I don't think the stats are very accurate. This seems to often move the s_waitcnt down into a divergent branch, but the wait still happens later if the branch isn't taken, so the wait is counted twice.
