[PATCH] D99249: [PassManager] Run additional LICM before LoopRotate

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

> I.e. we end up with less instructions, more LICM activity (+30% more sunks out of loops!),

This sounds too good to be true ... and it is. The statistic was closer to counting sinking candidates than actually sunk instructions. I've fixed it in 8a168d2d70678164004fca8de78e98bfb6e1272d <https://reviews.llvm.org/rG8a168d2d70678164004fca8de78e98bfb6e1272d> and would expect this patch to have a much more limited impact on it now.
