Wrappers for CTF/BTF to fetch information from GCC DWARF DIE. Used in ctfc.cc. 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.
Source location information.
CTF Types' and CTF Variables' Location Information. CTF section does not emit location information, this is provided for BTF CO-RE use-cases. These functions fetch information from DWARF Die directly, as such the location information is not buffered in the CTF container.
References dwarf_file_data::filename, get_AT_file(), and NULL.
