            Bug ID: 31428
           Summary: ptype should respect "set print vtbl"
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

With "set print vtbl on", I think ptype should also show
the vtable.

struct q {
  virtual ~q () =3D default;
  int x =3D 23;
};

q qqq;


(gdb) set print vtbl on
(gdb) ptype q
type =3D struct q {
  public:
    int x;

    ~q();
}


It would also be nice to have a ptype flag to enable this
per-use.

Finally, perhaps ptype/o should always show the vtables, since
the point of this is to understand the layout of the object in
memory.
