[cfe-commits] [PATCH review request] unused overloaded expression should error

[Faisal Vali]

This patch is peripherally related to my previous patch regarding bug 7505.


I stumbled upon the following test code, that should error, but doesn't.

void two() { }
void two(int) { }

int main()
{
  two; // clang emits unused variable warning, but this should be an error -
}

The attached patch ensures that clang produces an error.

Would appreciate any feedback :)
thanks!
