40 A CTF container does not store all debug information internally. Some of
41 the info is fetched indirectly via the DIE reference available in each CTF
42 container entry.

44 These functions will be used by the CTF container to give access to its
45 consumers (CTF/BTF) to various debug information available in DWARF DIE.

47 of CTF/BTF information is not ideal. */
