I can confirm it on trunk and the issue is that we prefer load-lanes for f3 instead of SLP. This issue will go away when we do load-lanes from SLP, so it's intermittent (but I can't promise any timeline). I wonder if the FAIL also occurs on aarch64. There's vect_load_lanes to eventually "fix" the FAIL by adjusting the testcase expectation. ^ permalink raw reply [flat|nested] 5+ messages in thread
