|
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
|
2005-01-27 17:45:09 +01:00
|
|
|
|
full object, not just the limited portion apparent from the
|
|
|
|
|
compile-time type.
|
2003-05-11 01:10:08 +02:00
|
|
|
|
|
|
|
|
|
- If `type' has virtual base classes, then even printing `type'
|
2005-01-27 17:45:09 +01:00
|
|
|
|
alone may require reaching outside the `type' portion of the
|
|
|
|
|
object to wherever the virtual base class has been stored.
|
2003-05-11 01:10:08 +02:00
|
|
|
|
|
|
|
|
|
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
|
2005-01-27 17:45:09 +01:00
|
|
|
|
-- 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.)
|
2003-05-11 01:10:08 +02:00
|
|
|
|
|
|
|
|
|
If we're not doing anything fancy, `enclosing_type' is equal to
|
|
|
|
|
`type', and `embedded_offset' is zero, so everything works
|
|
|
|
|
normally. */
