  25
  26 2019-07-08  Nick Alcock  <nick.alcock@oracle.com>
  27
  28         * ctf-impl.h (ctf_file_t): New field ctf_openflags.
  29         * ctf-open.c (ctf_bufopen): Set it.  No longer dump header offsets.

  31         (ctf_dump): Call it.
  32         (ctf_dump_header_strfield): New function.
  33         (ctf_dump_header_sectfield): Likewise.
  34
  35 2019-07-06  Nick Alcock  <nick.alcock@oracle.com>
  36
  37         * ctf-impl.h (ctf_file_t): New fields ctf_header, ctf_dynbase,
  38         ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
  39         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
  40         ctf_base: do not assume that it is always sizeof (ctf_header_t).
  41         Print out ctf_cuname: only print out ctf_parname if set.
  42         (ctf_free_base): Removed, ctf_base is no longer freed: free
  43         ctf_dynbase instead.
  44         (ctf_set_version): Fix spacing.
  45         (upgrade_header): New, in-place header upgrading.
  46         (upgrade_types): Rename to...
  47         (upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No
  48         longer track old and new headers separately.  No longer allow for
  49         header sizes explicitly: squeeze the headers out on upgrade (they
  50         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
  51         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.
  52         (upgrade_types): New, also handle ctf_parmax updating.
  53         (flip_header): Flip ctf_cuname.
  54         (flip_types): Flip BUF explicitly rather than deriving BUF from
  55         BASE.
  56         (ctf_bufopen): Store the header in fp->ctf_header.  Correct minimum
  57         required alignment of objtoff and funcoff.  No longer store it in
  58         the ctf_buf unless that buf is derived unmodified from the input.
  59         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
  60         that duplicate fields in ctf_file: move allocation of ctf_file
  61         further up instead.  Call upgrade_header as needed.  Move
  62         version-specific ctf_parmax initialization into upgrade_types.  More
  63         concise error handling.
  64         (ctf_file_close): No longer test for null pointers before freeing.
  65         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call
  66         ctf_free_base.
  67         (ctf_cuname): New.
  68         (ctf_cuname_set): New.
  69         * ctf-create.c (ctf_update): Populate ctf_cuname.
  70         (ctf_gzwrite): Write out the header explicitly.  Remove obsolescent
  71         comment.
  72         (ctf_write): Likewise.
  73         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
  74         Fix the compression length: fp->ctf_size never counted the CTF
  75         header.  Simplify the compress call accordingly.
  76
  77 2019-07-11  Hans-Peter Nilsson  <hp@bitrange.com>
  78
  79         * ctf-endian.h: Don't assume htole64 and le64toh are always
  80         present if HAVE_ENDIAN_H; also check if htole64 is defined.
  81         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
  82         not bswap_identity_64.
  83
  84 2019-09-18  Alan Modra  <amodra@gmail.com>
  85
  86         * ctf-open-bfd.c: Update throughout for bfd section macro changes.

 103
 104 2019-06-28  Nick Alcock  <nick.alcock@oracle.com>
 105

 109         (struct ctf_str_atom): New, disambiguated single string.
 110         (struct ctf_str_atom_ref): New, points to some other location that
 111         references this string's offset.
 112         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
 113         Remove member ctf_dtvstrlen: we no longer track the total strlen
 114         as we add strings.
 115         (ctf_str_create_atoms): Declare new function in ctf-string.c.
 116         (ctf_str_free_atoms): Likewise.

 125         (ctf_file_close): Destroy it.
 126         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
 127         special-case the position of the parname string.  Construct the
 128         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
 129         rest of each buffer element is constructed, not via open-coding:
 130         realloc the CTF buffer and append the strtab to it.  No longer
 131         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
 132         strtab construction.
 133         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
 134         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
 135         after buffer element construction instead.
 136         (ctf_copy_lmembers): Likewise.
 137         (ctf_copy_emembers): Likewise.

 146         * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts
 147         if there are active ctf_str_num_refs.
 148         (ctf_strraw): Move to ctf-string.c.
 149         (ctf_strptr): Likewise.

 179         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
 180         little-endian CTF archive magic.  Do not check the CTF version:
 181         ctf_simple_open does that in endian-safe ways.  Do not dereference
 182         null pointers on open failure.
 183
 184 2019-06-19  Nick Alcock  <nick.alcock@oracle.com>
