[PATCH] D99718: [LoopVectorize] Simplify scalar cost calculation in getInstructionCost

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.
Herald added a project: All.

Unfortunately another case surfaced where we a scalarized instruction requiring multiple copies reaches getInstructionCost and triggers the assert: https://github.com/llvm/llvm-project/issues/55096. I don't think this can be handled easily, so I put up a patch to undo the changes: D125533 <https://reviews.llvm.org/D125533>. Not sure if there are any better alternatives.
