   4         * ctf-open.c (ctf_bufopen): Set it.  No longer dump header offsets.
   5         * ctf-dump.c (dump_header): New function, dump the CTF header.
   6         (ctf_dump): Call it.

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

  79 2019-06-28  Nick Alcock  <nick.alcock@oracle.com>
  80
  81         * ctf-impl.h: (struct ctf_strs_writable): New, non-const version of

  84         (struct ctf_str_atom): New, disambiguated single string.
  85         (struct ctf_str_atom_ref): New, points to some other location that
  86         references this string's offset.
  87         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
  88         Remove member ctf_dtvstrlen: we no longer track the total strlen
  89         as we add strings.
  90         (ctf_str_create_atoms): Declare new function in ctf-string.c.

 100         (ctf_file_close): Destroy it.
 101         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
 102         special-case the position of the parname string.  Construct the
 103         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
 104         rest of each buffer element is constructed, not via open-coding:
 105         realloc the CTF buffer and append the strtab to it.  No longer
 106         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
 107         strtab construction.
 108         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
 109         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
 110         after buffer element construction instead.
 111         (ctf_copy_lmembers): Likewise.
 112         (ctf_copy_emembers): Likewise.

 121         * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts
 122         if there are active ctf_str_num_refs.
 123         (ctf_strraw): Move to ctf-string.c.
 124         (ctf_strptr): Likewise.

 154         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
 155         little-endian CTF archive magic.  Do not check the CTF version:
 156         ctf_simple_open does that in endian-safe ways.  Do not dereference
 157         null pointers on open failure.
 158
 159 2019-06-19  Nick Alcock  <nick.alcock@oracle.com>
