[PATCH] D76500: WIP: GlobalISel: Lower funnel shifts

[Jay Foad via Phabricator via llvm-commits]

Reverse ping! We are now seeing funnel shifts in the wild, because InstCombine has started generating them. Can this patch go in as-is? Are there correctness problems or is it just a matter of optimizing the udiv/urem into shifts?
