   6         (ctf_new_archive_internal): Improve comment.
   7         * ctf-archive.c (ctf_arc_close): Do not free the ctfi_strsect.
   8         * ctf-open.c (ctf_bufopen): Allow opening with a string section but
   9         no symbol section, but not vice versa.
  10
  11 2019-07-08  Nick Alcock  <nick.alcock@oracle.com>
  12
  13         * ctf-impl.h (ctf_file_t): New field ctf_openflags.
  14         * ctf-open.c (ctf_bufopen): Set it.  No longer dump header offsets.
  15         * ctf-dump.c (dump_header): New function, dump the CTF header.
  16         (ctf_dump): Call it.
  17         (ctf_dump_header_strfield): New function.
  18         (ctf_dump_header_sectfield): Likewise.
  19
  20 2019-07-06  Nick Alcock  <nick.alcock@oracle.com>
  21
  22         * ctf-impl.h (ctf_file_t): New fields ctf_header, ctf_dynbase,
  23         ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
  24         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
  25         ctf_base: do not assume that it is always sizeof (ctf_header_t).
  26         Print out ctf_cuname: only print out ctf_parname if set.
  27         (ctf_free_base): Removed, ctf_base is no longer freed: free
  28         ctf_dynbase instead.
  29         (ctf_set_version): Fix spacing.
  30         (upgrade_header): New, in-place header upgrading.
  31         (upgrade_types): Rename to...
  32         (upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No
  33         longer track old and new headers separately.  No longer allow for
  34         header sizes explicitly: squeeze the headers out on upgrade (they
  35         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
  36         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.
  37         (upgrade_types): New, also handle ctf_parmax updating.
  38         (flip_header): Flip ctf_cuname.
  39         (flip_types): Flip BUF explicitly rather than deriving BUF from
  40         BASE.
  41         (ctf_bufopen): Store the header in fp->ctf_header.  Correct minimum
  42         required alignment of objtoff and funcoff.  No longer store it in
  43         the ctf_buf unless that buf is derived unmodified from the input.
  44         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
  45         that duplicate fields in ctf_file: move allocation of ctf_file
  46         further up instead.  Call upgrade_header as needed.  Move
  47         version-specific ctf_parmax initialization into upgrade_types.  More
  48         concise error handling.
  49         (ctf_file_close): No longer test for null pointers before freeing.
  50         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call
  51         ctf_free_base.
  52         (ctf_cuname): New.
  53         (ctf_cuname_set): New.
  54         * ctf-create.c (ctf_update): Populate ctf_cuname.
  55         (ctf_gzwrite): Write out the header explicitly.  Remove obsolescent
  56         comment.
  57         (ctf_write): Likewise.
  58         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
  59         Fix the compression length: fp->ctf_size never counted the CTF
  60         header.  Simplify the compress call accordingly.
  61
  62 2019-07-11  Hans-Peter Nilsson  <hp@bitrange.com>
  63
  64         * ctf-endian.h: Don't assume htole64 and le64toh are always
  65         present if HAVE_ENDIAN_H; also check if htole64 is defined.
  66         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
  67         not bswap_identity_64.
  68
  69 2019-09-18  Alan Modra  <amodra@gmail.com>
  70
  71         * ctf-open-bfd.c: Update throughout for bfd section macro changes.
  72

  88
  89 2019-06-28  Nick Alcock  <nick.alcock@oracle.com>
  90
  91         * ctf-impl.h: (struct ctf_strs_writable): New, non-const version of

  94         (struct ctf_str_atom): New, disambiguated single string.
  95         (struct ctf_str_atom_ref): New, points to some other location that
  96         references this string's offset.
  97         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
  98         Remove member ctf_dtvstrlen: we no longer track the total strlen
  99         as we add strings.
 100         (ctf_str_create_atoms): Declare new function in ctf-string.c.

 110         (ctf_file_close): Destroy it.
 111         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
 112         special-case the position of the parname string.  Construct the
 113         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
 114         rest of each buffer element is constructed, not via open-coding:
 115         realloc the CTF buffer and append the strtab to it.  No longer
 116         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
 117         strtab construction.
 118         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
 119         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
 120         after buffer element construction instead.

 131         * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts
 132         if there are active ctf_str_num_refs.
 133         (ctf_strraw): Move to ctf-string.c.
 134         (ctf_strptr): Likewise.

 164         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
 165         little-endian CTF archive magic.  Do not check the CTF version:
 166         ctf_simple_open does that in endian-safe ways.  Do not dereference
 167         null pointers on open failure.
 168
 169 2019-06-19  Nick Alcock  <nick.alcock@oracle.com>
