Peter Collingbourne	bc0705240e	IR: Move NumElements field from {Array,Vector}Type to SequentialType. ... Now that PointerType is no longer a SequentialType, all SequentialTypes have an associated number of elements, so we can move that information to the base class, allowing for a number of simplifications.

Erik Eckstein	c1d52e5c53	FunctionComparator: don't rely on argument evaluation order. ... This is a follow-up on the recent refactoring of the FunctionMerge pass. It should fix a fail of the new FunctionComparator unittest whe compiling with MSVC. llvm-svn: 286648	2016-11-11 22:21:39 +00:00
Erik Eckstein	4d6fb72aa9	Make the FunctionComparator of the MergeFunctions pass a stand-alone utility. ... 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	2016-11-11 21:15:13 +00:00
