4 of...
5 (ctf_arc_write_fd): ... this new function.
6 * ctf-create.c (ctf_write_mem): New.
7
8 2019-07-13 Nick Alcock <nick.alcock@oracle.com>
9
10 * ctf-impl.h (ctf_str_atom_t) <csa_offset>: New field.
11 (ctf_file_t) <ctf_syn_ext_strtab>: Likewise.
12 (ctf_str_add_ref): Name the last arg.
13 (ctf_str_add_external) New.
14 (ctf_str_add_strraw_explicit): Likewise.
15 (ctf_simple_open_internal): Likewise.
16 (ctf_bufopen_internal): Likewise.
17
18 * ctf-string.c (ctf_strraw_explicit): Split from...
19 (ctf_strraw): ... here, with new support for ctf_syn_ext_strtab.
20 (ctf_str_add_ref_internal): Return the atom, not the
21 string.
22 (ctf_str_add): Adjust accordingly.
23 (ctf_str_add_ref): Likewise. Move up in the file.
24 (ctf_str_add_external): New: update the csa_offset.
25 (ctf_str_count_strtab): Only account for strings with no csa_offset
26 in the internal strtab length.
27 (ctf_str_write_strtab): If the csa_offset is set, update the
28 string's refs without writing the string out, and update the
29 ctf_syn_ext_strtab. Make OOM handling less ugly.
30 * ctf-create.c (struct ctf_sort_var_arg_cb): New.
31 (ctf_update): Handle failure to populate the strtab. Pass in the
32 new ctf_sort_var arg. Adjust for ctf_syn_ext_strtab addition.
33 Call ctf_simple_open_internal, not ctf_simple_open.
34 (ctf_sort_var): Call ctf_strraw_explicit rather than looking up
35 strings by hand.
36 * ctf-hash.c (ctf_hash_insert_type): Likewise (but using
37 ctf_strraw). Adjust to diagnose ECTF_STRTAB nonetheless.

44 (ctf_bufopen_internal): ... this new function, which sets
45 ctf_syn_ext_strtab.
46

52
53 * ctf-open.c (init_symtab): Check for overflow against the right
54 section.

56 (upgrade_types_v1): Note that these sections are not checked.
57 (flip_header): Endian-swap the header fields.
58 (flip_ctf): Endian-swap the sections.

62 2019-07-13 Nick Alcock <nick.alcock@oracle.com>
63
64 * ctf-open-bfd.c: Add <assert.h>.
65 (ctf_bfdopen_ctfsect): Open string and symbol tables using
66 techniques borrowed from bfd_elf_sym_name.
67 (ctf_new_archive_internal): Improve comment.
68 * ctf-archive.c (ctf_arc_close): Do not free the ctfi_strsect.
69 * ctf-open.c (ctf_bufopen): Allow opening with a string section but
70 no symbol section, but not vice versa.
71
72 2019-07-08 Nick Alcock <nick.alcock@oracle.com>
73
74 * ctf-impl.h (ctf_file_t): New field ctf_openflags.
75 * ctf-open.c (ctf_bufopen): Set it. No longer dump header offsets.
76 * ctf-dump.c (dump_header): New function, dump the CTF header.
77 (ctf_dump): Call it.
78 (ctf_dump_header_strfield): New function.
79 (ctf_dump_header_sectfield): Likewise.
80
81 2019-07-06 Nick Alcock <nick.alcock@oracle.com>
82
83 * ctf-impl.h (ctf_file_t): New fields ctf_header, ctf_dynbase,
84 ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
85 * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
86 ctf_base: do not assume that it is always sizeof (ctf_header_t).
87 Print out ctf_cuname: only print out ctf_parname if set.
88 (ctf_free_base): Removed, ctf_base is no longer freed: free
89 ctf_dynbase instead.
90 (ctf_set_version): Fix spacing.
91 (upgrade_header): New, in-place header upgrading.
92 (upgrade_types): Rename to...
93 (upgrade_types_v1): ... this. Free ctf_dynbase, not ctf_base. No
94 longer track old and new headers separately. No longer allow for
95 header sizes explicitly: squeeze the headers out on upgrade (they
96 are preserved in fp->ctf_header). Set ctf_dynbase, ctf_base and
97 ctf_buf explicitly. Use ctf_free, not ctf_free_base.
98 (upgrade_types): New, also handle ctf_parmax updating.
99 (flip_header): Flip ctf_cuname.
100 (flip_types): Flip BUF explicitly rather than deriving BUF from
101 BASE.
102 (ctf_bufopen): Store the header in fp->ctf_header. Correct minimum
103 required alignment of objtoff and funcoff. No longer store it in
104 the ctf_buf unless that buf is derived unmodified from the input.
105 Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
106 that duplicate fields in ctf_file: move allocation of ctf_file
107 further up instead. Call upgrade_header as needed. Move
108 version-specific ctf_parmax initialization into upgrade_types. More
109 concise error handling.
110 (ctf_file_close): No longer test for null pointers before freeing.
111 Free ctf_dyncuname, ctf_dynbase, and ctf_header. Do not call
112 ctf_free_base.
113 (ctf_cuname): New.
114 (ctf_cuname_set): New.
115 * ctf-create.c (ctf_update): Populate ctf_cuname.
116 (ctf_gzwrite): Write out the header explicitly. Remove obsolescent
117 comment.
118 (ctf_write): Likewise.
119 (ctf_compress_write): Get the header from ctf_header, not ctf_base.
120 Fix the compression length: fp->ctf_size never counted the CTF
121 header. Simplify the compress call accordingly.
122
123 2019-07-11 Hans-Peter Nilsson <hp@bitrange.com>
124
125 * ctf-endian.h: Don't assume htole64 and le64toh are always
126 present if HAVE_ENDIAN_H; also check if htole64 is defined.
127 [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
128 not bswap_identity_64.
129
130 2019-09-18 Alan Modra <amodra@gmail.com>
131
132 * ctf-open-bfd.c: Update throughout for bfd section macro changes.

155 (struct ctf_str_atom): New, disambiguated single string.
156 (struct ctf_str_atom_ref): New, points to some other location that
157 references this string's offset.
158 (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
159 Remove member ctf_dtvstrlen: we no longer track the total strlen
160 as we add strings.

171 (ctf_file_close): Destroy it.
172 * ctf-create.c (ctf_update): Copy-and-free it on update. No longer
173 special-case the position of the parname string. Construct the
174 strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
175 rest of each buffer element is constructed, not via open-coding:
176 realloc the CTF buffer and append the strtab to it. No longer
177 maintain ctf_dtvstrlen. Sort the variable entry table later, after
178 strtab construction.
179 (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
180 (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref

225 (ctf_fdopen): Check for endian-swapped raw CTF magic, and
226 little-endian CTF archive magic. Do not check the CTF version:
227 ctf_simple_open does that in endian-safe ways. Do not dereference
228 null pointers on open failure.

231
232 * ctf-open.c (get_vbytes_common): Return the new slice size.

257 the buffer again on compression error.
