--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It looks like a mismatch of epilogue vectorization expectation? Adding
--param vect-epilogues-nomask=0 to all gets

[^\\n]* = foo\\.simdclone" 3

and dropping yields

and the logs show we see 3 all the times. If you tried to match what
targets do automatically that's a lost cause - I suggest to disable
epilog vectorization instead in all testcases.
