[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak added inline comments.


================
Comment at: clang/lib/CodeGen/CGObjC.cpp:1856
+      Selector IsKindOfClassSel = C.Selectors.getSelector(
+          llvm::array_lengthof(IsKindOfClassII), &IsKindOfClassII[0]);
+      CallArgList IsKindOfClassArgs;
----------------
Can you use `GetUnarySelector` here?


================
Comment at: clang/lib/CodeGen/CGObjC.cpp:1860
+          CGM.getObjCRuntime().GetClass(*this, InterfaceTy->getDecl());
+      Args.add(RValue::get(Cls), C.getObjCClassType());
+      llvm::Value *IsClass =
----------------
It looks like `Args` should be cleared before adding the argument. Or should the argument be added to `IsKindOfClassArg`?
