[PATCH] D125299: [ValueTracking] Enable -branch-on-poison-as-ub by default

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Sounds good to me in general. I think there are at least 2 known issues with SimplifyCFG & LoopUnroll introducing branches on poison/undef. Linked to https://github.com/llvm/llvm-project/issues/45489. If you know of other issues in that area it might be good to all link them to that issue, so it is easier to keep track of the outstanding issues
