98 object's compile-time type. If the object actually belongs to some
99 class derived from `type', perhaps with other base classes and
100 additional members, then `type' is just a subobject of the real
101 thing, and the full object is probably larger than `type' would
104 If `type' is a dynamic class (i.e. one with a vtable), then GDB can
105 actually determine the object's run-time type by looking at the
106 run-time type information in the vtable. When this information is
107 available, we may elect to read in the entire object, for several
110 - When printing the value, the user would probably rather see the
111 full object, not just the limited portion apparent from the
114 - If `type' has virtual base classes, then even printing `type'
115 alone may require reaching outside the `type' portion of the
116 object to wherever the virtual base class has been stored.
118 When we store the entire object, `enclosing_type' is the run-time
119 type -- the complete object -- and `embedded_offset' is the offset
120 of `type' within that larger type, in bytes. The value_contents()
121 macro takes `embedded_offset' into account, so most GDB code
122 continues to see the `type' portion of the value, just as the
125 If `type' is a pointer to an object, then `enclosing_type' is a
126 pointer to the object's run-time type, and `pointed_to_offset' is
127 the offset in bytes from the full object to the pointed-to object
128 -- that is, the value `embedded_offset' would have if we followed
129 the pointer and fetched the complete object. (I don't really see
130 the point. Why not just determine the run-time type when you
131 indirect, and avoid the special case? The contents don't matter
132 until you indirect anyway.)
