In fact, the swift compiler enables MergeFunctions by default when optimizing, along with an even more aggressive merging pass which handles equivalence-modulo-constant-uses (https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp <https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp>).

Is anyone actively working on enabling MergeFunctions in LLVM's default pipelines? Is there a roadmap for doing so? ISTM that preventing miscompiles when merging functions is a serious, unsolved problem. I.e., it's hard for the MergeFunctions pass to be *really sure* that two fu...
