Nick Alcock 143dce8481 libctf: ELF file opening via BFD ... These functions let you open an ELF file with a customarily-named CTF section in it, automatically opening the CTF file or archive and associating the symbol and string tables in the ELF file with the CTF container, so that you can look up the types of symbols in the ELF file via ctf_lookup_by_symbol(), and so that strings can be shared between the ELF file and CTF container, to save space. It uses BFD machinery to do so. This has now been lightly tested and seems to work. In particular, if you already have a bfd you can pass it in to ctf_bfdopen(), and if you want a bfd made for you you can call ctf_open() or ctf_fdopen(), optionally specifying a target (or try once without a target and then again with one if you get ECTF_BFD_AMBIGUOUS back). We use a forward declaration for the struct bfd in ctf-api.h, so that ctf-api.h users are not required to pull in <bfd.h>. (This is mostly for the sake of readelf.) libctf/ * ctf-open-bfd.c: New file. * ctf-open.c (ctf_close): New. * ctf-impl.h: Include bfd.h. (ctf_file): New members ctf_data_mmapped, ctf_data_mmapped_len. (ctf_archive_internal): New members ctfi_abfd, ctfi_data, ctfi_bfd_close. (ctf_bfdopen_ctfsect): New declaration. (_CTF_SECTION): likewise. include/ * ctf-api.h (struct bfd): New forward. (ctf_fdopen): New. (ctf_bfdopen): Likewise. (ctf_open): Likewise. (ctf_arc_open): Likewise.		2019-05-28 17:08:08 +01:00
