[PATCH] D87399: Revert "[InstCombine] erase instructions leading up to unreachable"

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Just to be clear, it **is** okay to revert this, but you need to adjust your rationale in the description to be one of two things:

- This broke BigProject due to reliance on undefined behavior, we need a day to fix it. Will reapply once done.
- I plan to (expeditiously) submit an RFC to llvm-dev that changes the behavior of volatile operations in LLVM, undoing the decision from D53184 <https://reviews.llvm.org/D53184>. Will reapply once that discussion is finished.
