Test case?



================
Comment at: lib/CodeGen/CGBuiltin.cpp:1563
+    Value *Result = Builder.CreateCall(F, {Tmp, Builder.getTrue()});
+    if (Result->getType() != ResultType)
+      Result = Builder.CreateIntCast(Result, ResultType, /*isSigned*/true,
----------------
CreateIntCast just does nothing if the types match, so this check isn't needed.
