[PATCH] D85283: [ARM][CostModel] Implement getCFInstrCost

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Do you mean it's the cost of a phi that is altering things? They certainly sounds like they should be free most of the time. Even for codesize I would expect them to be folded away a lot of the time. You just have to get the inputs to share a register after all.
