37 /* The structure which defines the type of a value.  It should never
89   struct type *type;
91   /* If a value represents a C++ object, then the `type' field gives
92      the object's compile-time type.  If the object actually belongs
93      to some class derived from `type', perhaps with other base
94      classes and additional members, then `type' is just a subobject
96      `type' would suggest.
98      If `type' is a dynamic class (i.e. one with a vtable), then GDB
99      can actually determine the object's run-time type by looking at
100      the run-time type information in the vtable.  When this
106        compile-time type.
108      - If `type' has virtual base classes, then even printing `type'
109        alone may require reaching outside the `type' portion of the
113      type -- the complete object -- and `embedded_offset' is the
114      offset of `type' within that larger type, in bytes.  The
116      most GDB code continues to see the `type' portion of the value,
119      If `type' is a pointer to an object, then `enclosing_type' is a
120      pointer to the object's run-time type, and `pointed_to_offset' is
124      really see the point.  Why not just determine the run-time type
129      `type', and `embedded_offset' is zero, so everything works
