--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, load-lane support should be unaffected (but I didn't test obviously).  I
hope aarch64 folks can investigate - eventually the permute check done in
vectorizable_load needs adjustment / moving.

I've reproduced this failure on arm-none-eabi, aarch64-none-elf, and
aarch64-linux-gnu.

I believe this was introduced in bc484e250990393e887f7239157cc85ce6fadcce.

Re-testing with a cross shows exactly one "permutation requires at least three
vectors" so I assume fixed.
