             Bug #: 11621
           Summary: Clang does not properly implement -Woverloaded-virtual
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

% cat x.cc
struct Base {
  virtual void f(int);
  virtual void f(float);
};

struct Dervied : Base {
  virtual void f(int);
};

% ./bin/clang -fsyntax-only -Woverloaded-virtual x.cc

% gcc -fsyntax-only -Woverloaded-virtual x.cc
x.cc:3:16: warning: 'virtual void Base::f(float)' was hidden
[-Woverloaded-virtual]
x.cc:7:16: warning:   by 'virtual void Dervied::f(int)' [-Woverloaded-virtual]


This warning has a very high value. I don't even know why it isn't in -Wall. =[
