+ the object's compile-time type. If the object actually belongs
+ to some 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
+ normally. */
