lebedev.ri added inline comments.

================
Comment at: cfe/trunk/lib/CodeGen/BackendUtil.cpp:1426-1431
   EmitAssemblyHelper AsmHelper(Diags, HeaderOpts, CGOpts, TOpts, LOpts, M);
 
   if (CGOpts.ExperimentalNewPassManager)
     AsmHelper.EmitAssemblyWithNewPassManager(Action, std::move(OS));
   else
     AsmHelper.EmitAssembly(Action, std::move(OS));
----------------
This isn't covered by any timer; if you look in `BackendUtil.cpp`,
`EmitAssemblyHelper` actually has `CodeGenerationTime("codegen", "Code 
Generation Time")` timer.


================
Comment at: llvm/trunk/lib/IR/LegacyPassManager.cpp:1686
 
+  llvm::TimeTraceScope TimeScope("OptModule", M.getName());
   for (Function &F : M)
----------------
I think this may be the wrong place for this.
This includes the entirety of the pipeline, including all of llvm back-end 
stuff.
