/* Wrappers for CTF/BTF to fetch information from GCC DWARF DIE.  Used in

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

   These functions will be used by the CTF container to give access to its
   consumers (CTF/BTF) to various debug information available in DWARF DIE.
   Direct access to debug information in GCC dwarf structures by the consumers
   of CTF/BTF information is not ideal.  */
