[PATCH] D89952: [SelectionDAG] Enable CTPOP optimization fine tuning

Mon Oct 26 13:57:45 PDT 2020

spatel added a comment.

I added another IR fold for ctpop here: 5a6e66ec7238 <https://reviews.llvm.org/rG5a6e66ec72382d370046e04c415f8c3cb7e8b68d>

So now I can't tell from the test diffs what the real motivating cases are. We usually like test coverage, but I wonder if we should remove tests for all of the un-optimized IR patterns that we now expect to be folded in IR.
