Hello Rick,

Since nobody responded, I'll try.  :-)

rick shelton <thatrickguy@yahoo.com> a =C3=A9crit:

Let's say the type "A" is represented by type_a.  Foo is then
represented by a FUNCTION_DECL tree node that is accessible from the
list of methods of type_a, that you can get from TYPE_METHODS (type_a).

You can walk these methods by doing:

    {
      /*  method is going to be a tree node
          of FUNCTION_DECL kind.  */
      tree method;
      for (method =3D TYPE_METHOD (type_a);
           method;
           method =3D DECL_CHAIN (method))
        /* Do something with method*/;
    }

Then the body of the function can be accessed from the=20
DECL_INITIAL (method) accessor.

I hope this helps.
