This is pure refactoring. NFC. This change moves the FunctionComparator (together with the GlobalNumberState utility) in to a separate file so that it can be used by other passes. For example, the SwiftMergeFunctions pass in the Swift compiler: https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp Details of the change: *) The big part is just moving code out of MergeFunctions.cpp into FunctionComparator.h/cpp *) Make FunctionComparator member functions protected (instead of private) so that a derived comparator class can use them. Following refactoring helps to share code between the base FunctionComparator class and a derived class: *) Add a beginCompare() function *) Move some basic function property comparisons into a separate function compareSignature() *) Do the GEP comparison inside cmpOperations() which now has a new needToCmpOperands reference parameter https://reviews.llvm.org/D25385 llvm-svn: 286632 |
