--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
This also wasn't seen in precommit CI. 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.

We also see it on arm --with-mode=thumb.
FWIW this is being tracked in the Linaro CI at:
