Thanks! Can you add a test somewhere?  `grep -R W.*uninitialized test/Sema*` will probably show you the existing test for this code. (Another technique: Comment some of the existing tests, run `ninja check-clang`, and see which tests start failing.)

You can run an individual test via `bin/llvm-lit ../../llvm/tools/clang/test/Sema/mytest.cc`.



================
Comment at: clang/lib/Sema/AnalysisBasedWarnings.cpp:907
     else
       DiagUninitUse(S, VD, Use, true);
   }
----------------
Should the check be in DiagUninitUse()? Or is there a reason this one should happen for volatiles?
