[PATCH] D28166: Properly merge K&R functions that have attributes

[Reid Kleckner via Phabricator via cfe-commits]

rnk added inline comments.


================
Comment at: lib/CodeGen/CodeGenFunction.h:3570
     for (auto *A : llvm::make_range(Arg, ArgRange.end()))
-      ArgTypes.push_back(getVarArgType(A));
+      ArgTypes.push_back(getVarArgType(A, CallArgTypeInfo == nullptr));
 
----------------
I'm testing this change:
```
$ git diff
diff --git a/lib/CodeGen/CodeGenFunction.h b/lib/CodeGen/CodeGenFunction.h

```

I'd like to fix this issue in a separate commit.
