/* To help us find the components of a vtable, we build ourselves a
GDB type object representing the vtable structure. Following the
V3 ABI, it goes something like this:
struct gdb_gnu_v3_abi_vtable {
/ * An array of virtual call and virtual base offsets. The real
length of this array depends on the class hierarchy; we use
negative subscripts to access the elements. Yucky, but
better than the alternatives. * /
ptrdiff_t vcall_and_vbase_offsets[0];
/ * The offset from a virtual pointer referring to this table
to the top of the complete object. * /
ptrdiff_t offset_to_top;
/ * The type_info pointer for this class. This is really a
std::type_info *, but GDB doesn't really look at the
type_info object itself, so we don't bother to get the type
exactly right. * /
void *type_info;
/ * Virtual table pointers in objects point here. * /
/ * Virtual function pointers. Like the vcall/vbase array, the
real length of this table depends on the class hierarchy. * /
void (*virtual_functions[0]) ();

The catch, of course, is that the exact layout of this table
depends on the ABI --- word size, endianness, alignment, etc. So
the GDB type object is actually a per-architecture kind of thing.
