...l DSO's). The numbers are even more compelling for Swift code. 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...
