[PATCH] D111495: [IndVars] Invalidate SCEV when IR is changed in rewriteLoopExitValue.

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

This looks like basically the same change as D82799 <https://reviews.llvm.org/D82799>, though there I thought this was just a compile-time optimization, not a correctness fix. In that patch, I also added an extra forgetValue() call in IV widening to prevent the elim-extend.ll test change.
