  29
  30         * ctf-impl.h: (struct ctf_strs_writable): New, non-const version of
  31         struct ctf_strs.
  32         (struct ctf_dtdef): Note that dtd_data.ctt_name is unpopulated.
  33         (struct ctf_str_atom): New, disambiguated single string.
  34         (struct ctf_str_atom_ref): New, points to some other location that
  35         references this string's offset.
  36         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
  37         Remove member ctf_dtvstrlen: we no longer track the total strlen
  38         as we add strings.
  39         (ctf_str_create_atoms): Declare new function in ctf-string.c.

  51         special-case the position of the parname string.  Construct the
  52         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
  53         rest of each buffer element is constructed, not via open-coding:
  54         realloc the CTF buffer and append the strtab to it.  No longer
  55         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
  56         strtab construction.
  57         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
  58         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref

  70         * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts
  71         if there are active ctf_str_num_refs.
  72         (ctf_strraw): Move to ctf-string.c.
  73         (ctf_strptr): Likewise.

 103         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
 104         little-endian CTF archive magic.  Do not check the CTF version:
 105         ctf_simple_open does that in endian-safe ways.  Do not dereference
 106         null pointers on open failure.
 107
 108 2019-06-19  Nick Alcock  <nick.alcock@oracle.com>

 112         Remember to copy in the CTF data when opening an uncompressed
