+ class derived from `type', perhaps with other base classes and
+ additional members, then `type' is just a subobject of the real
+ thing, and the full object is probably larger than `type' would
+ suggest.
+
+ If `type' is a dynamic class (i.e. one with a vtable), then GDB can
+ actually determine the object's run-time type by looking at the
+ run-time type information in the vtable. When this information is
+ available, we may elect to read in the entire object, for several
+ reasons:
+
+ - When printing the value, the user would probably rather see the
+ full object, not just the limited portion apparent from the
+ compile-time type.
+
+ - If `type' has virtual base classes, then even printing `type'
+ alone may require reaching outside the `type' portion of the
+ object to wherever the virtual base class has been stored.
+
+ When we store the entire object, `enclosing_type' is the run-time
+ type -- the complete object -- and `embedded_offset' is the offset
+ of `type' within that larger type, in bytes. The value_contents()
+ macro takes `embedded_offset' into account, so most GDB code
+ continues to see the `type' portion of the value, just as the
+ inferior would.
+
+ If `type' is a pointer to an object, then `enclosing_type' is a
+ pointer to the object's run-time type, and `pointed_to_offset' is
+ the offset in bytes from the full object to the pointed-to object
+ -- that is, the value `embedded_offset' would have if we followed
+ the pointer and fetched the complete object. (I don't really see
+ the point. Why not just determine the run-time type when you
+ indirect, and avoid the special case? The contents don't matter
+ until you indirect anyway.)
+
+ If we're not doing anything fancy, `enclosing_type' is equal to
+ `type', and `embedded_offset' is zero, so everything works
