[PATCH] D96399: [X86][CodeGenPrepare] Try to reuse IV's incremented value instead of adding the offset

[Philip Reames via Phabricator via llvm-commits]

I think we're at the point where if we do see problematic cases due to dom tree handling, we should just fix CGP to not use the current invalidation scheme.  Doing that is not a huge amount of work, and we're spending more time avoiding it than is warranted.

If necessary, I'll even volunteer to do it.  I will put that off until we have a motivating test case though.  :)
