--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yeah, I know. I tried to fix this for PR91178 but needed to revert. The
vectorizer issue uncovers places where we run into compile-time issues with
these large increment chains and I've fixed some but in the end a vectorizer
fix is required.
My mind tells me that at some point we limited the group gap but I didn't
find records of that. In the end it should be "easy" to avoid the bad
codegen, but vectorizable_load is kind-of a mess and hairy to adjust ...
I'll give it another try.
