Clang has a warning about overloading virtuals that triggers when a
derived class defines a virtual function that's an overload of
function in the base class. This kind of thing:
struct chart; // let's pretend this exists
struct Base
{
virtual void* get(char* e);
};
struct Derived: public Base {
virtual void* get(chart* e); // typo, we wanted to override the same function
};
The solution is to use
using Base::get;
to be explicit about the intention to reuse the base class virtual.
We hit this a lot with out glsl ir_hierarchical_visitor visitor
pattern, so let's adds some 'using' to calm down the compiler.
