--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ok, so we have an induction that's only used outside of the loop (well,
-fno-tree-scev-cprop ...) and this causes the VF to be reset to 1 as the
induction
computation is vect_unused_in_scope (should be used_by_induction I guess).
Caused by another change of mine I think.
Testing patch.
