PVS-Studio warning V524 for Clang

MapTy PerPtrTopDown;
MapTy PerPtrBottomUp;

void clearBottomUpPointers() {
  PerPtrTopDown.clear();
}

void clearTopDownPointers() {
  PerPtrTopDown.clear();
}

Most likely this is what should be written in clearBottomUpPointers(): PerPtrBottomUp.clear();

This suspicious code was found in Clang project by PVS-Studio static code analyzer.
Warning message is:
V524 It is odd that the body of 'clearTopDownPointers' function is fully equivalent to the body of 'clearBottomUpPointers' function (ObjCARC.cpp, line 1318). LLVMScalarOpts objcarc.cpp 1322
