<pre>Functions in a derived class which would otherwise be found by overload
resolution should be warned on at the call site. Eg)
(from test/SemaCXX/warn-overload-virtual.cpp)
namespace {
struct base {
void f(char) {}
};
struct derived : base {
void f(int) {}
};
void foo(derived &d) {
d.f('1'); // FIXME: this should warn about calling (anonymous
namespace)::derived::f(int)
// instead of (anonymous namespace)::base::f(char).
// Note: this should be under a new diagnostic flag and eventually
moved to a
// new test case since it's not strictly related to virtual
functions.
d.f(12); // This should not warn.
}
}
Since d.f('1') would call base::f(char) were it not hidden by derived::f(int),
that call should result in a warning and ideally a fix-it.
Note that this is not the property of the declaration so much as a property of
the call site.</pre>
