+
+       * ctf-impl.h (ctf_dict_t) <ctf_symtab_little_endian>: New.
+       (struct ctf_archive_internal) <ctfi_symsect_little_endian>: Likewise.
+       * ctf-create.c (ctf_serialize): Adjust for new field.
+       * ctf-open.c (init_symtab): Note the semantics of repeated calls.
+       (ctf_symsect_endianness): New.
+       (ctf_bufopen_internal): Set ctf_symtab_little_endian suitably for
+       the native endianness.
+       (_Static_assert): Moved...
+       (swap_thing): ... with this...
+       * swap.h: ... to here.
+       * ctf-util.c (ctf_elf32_to_link_sym): Use it, byteswapping the
+       Elf32_Sym if the ctf_symtab_little_endian demands it.
+       (ctf_elf64_to_link_sym): Likewise swap the Elf64_Sym if needed.
+       * ctf-archive.c (ctf_arc_symsect_endianness): New, set the
+       endianness of the symtab used by the dicts in an archive.
+       (ctf_archive_iter_internal): Initialize to unknown (assumed native,
+       do not call ctf_symsect_endianness).
+       (ctf_dict_open_by_offset): Call ctf_symsect_endianness if need be.
+       (ctf_dict_open_internal): Propagate the endianness down.
+       (ctf_dict_open_sections): Likewise.
+       * ctf-open-bfd.c (ctf_bfdopen_ctfsect): Get the endianness from the
+       struct bfd and pass it down to the archive.
+       * libctf.ver: Add ctf_symsect_endianness and
+       ctf_arc_symsect_endianness.
