2
3 * ctf-impl.h (ctf_file_t): Improve comments.
4 <ctf_link_cu_mapping>: Split into...
5 <ctf_link_in_cu_mapping>: ... this...
6 <ctf_link_out_cu_mapping>: ... and this.
7 * ctf-create.c (ctf_serialize): Adjust.
8 * ctf-open.c (ctf_file_close): Likewise.
9 * ctf-link.c (ctf_create_per_cu): Look things up in the
10 in_cu_mapping instead of the cu_mapping.
11 (ctf_link_add_cu_mapping): The deduplicating link will define
12 what happens if many FROMs share a TO.
13 (ctf_link_add_cu_mapping): Create in_cu_mapping and
14 out_cu_mapping. Do not create ctf_link_outputs here any more, or
15 create per-CU dicts here: they are already created when needed.
16 (ctf_link_one_variable): Log a debug message if we skip a
17 variable due to its type being concealed in a CU-mapped link.
18 (This is probably too common a case to make into a warning.)
19 (ctf_link): Create empty per-CU dicts if requested.

59 (ctf_link_lazy_open): New, open a CTF archive for linking when
60 needed.
61 (ctf_link_close_one_input_archive): New, close it again.
62 (ctf_link_one_input_archive): Adjust for lazy opening, member
63 renames, and ctf_err_warn transition. Move the
64 empty_link_type_mapping call to...
65 (ctf_link): ... here. Adjut for renamings and thunk removal.
66 Don't spuriously fail if some input contains no CTF data.
67 (ctf_link_write): ctf_err_warn transition.
68 * libctf.ver: Remove not-yet-stable comment.

84 to close a pre-existing parent. Set it to zero.
85 (ctf_import_unreffed): New, as above, setting
86 ctf_parent_unreffed to 1.
87 * ctf-create.c (ctf_serialize): Do not ctf_import into the new
88 child: use direct assignment, and set unreffed on the new and
89 old children.
90 * ctf-link.c (ctf_create_per_cu): Import the parent using
91 ctf_import_unreffed.
