[llvm-dev] [LV] [ScalarEvolution] Feedback on bug 34965 - After r311849 Loop Vectorizer crashes with "The instruction should be scalarized"

[Caballero, Diego via llvm-dev]

Hi!

I uploaded a tentative patch for the following bug in LV (https://bugs.llvm.org/show_bug.cgi?id=34965) but I have some concerns about it. I would appreciate if someone with more experience in SE/PSE can provide some feedback about current tentative fix and alternative solutions described in the comments.

Thanks!
