================
Comment at: llvm/lib/Transforms/Instrumentation/InstrProfiling.cpp:849
   // discarded.
+  bool ValueProfiling = enablesValueProfiling(*M);
   bool NeedComdat = needsComdatForCounter(*Fn, *M);
----------------
Probably define a helper : profDataReferencedInCode(). Currently it is the same as enablesValueProfiling, but may change in the future. It also makes code more readable.


================
Comment at: llvm/lib/Transforms/Instrumentation/InstrProfiling.cpp:857
+      auto GroupName = TT.isOSBinFormatCOFF() && ValueProfiling ? GV->getName()
+                                                                : CntsVarName;
       Comdat *C = M->getOrInsertComdat(GroupName);
----------------
why changing behavior on ELF?
