> I am not yet sure how to test it, since my example case (in the commit comment) was broken by the cost model change in 0d74fd3fdf50 <https://reviews.llvm.org/rG0d74fd3fdf5013e72c9c1682a284b8de7973a805>.

Can you actually link to it? I can't find it.

> Revert that to see this bad code transform I described there in brief to happen. Suggestions would be helpful!
