// ArchivePtrMarker is used to mark the location of pointers embedded in a CDS archive. E.g., when an
// InstanceKlass k is dumped, we mark the location of the k->_name pointer by effectively calling
// mark_pointer(/*ptr_loc=*/&k->_name). It's required that (_prt_base <= ptr_loc < _ptr_end). _ptr_base is
// fixed, but _ptr_end can be expanded as more objects are dumped.
