================
Comment at: tools/llvm-mca/Views/RegisterFileStatistics.cpp:25
+  RegisterFileUsage RFUEmpty = {0, 0, 0};
+  MoveEliminationInfo MEIEmpty = {0, 0, 0, 0, 0};
   if (!SM.hasExtraProcessorInfo()) {
----------------
You should be able to value initialize this RFUEmpty = {0}; MEIEmpty = {0};


================
Comment at: tools/llvm-mca/lib/HardwareUnits/RegisterFile.cpp:404
 
+void RegisterFile::addRegisterRead(ReadState &RS,
+                                   SmallVectorImpl<WriteRef> &DependentWrites) {
----------------
I think this routine can be marked const.
