 667         * ctf-create.c (struct ctf_sort_var_arg_cb): New.
 668         (ctf_update): Handle failure to populate the strtab.  Pass in the

 721         ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
 722         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
 723         ctf_base: do not assume that it is always sizeof (ctf_header_t).
 724         Print out ctf_cuname: only print out ctf_parname if set.
 725         (ctf_free_base): Removed, ctf_base is no longer freed: free
 726         ctf_dynbase instead.
 727         (ctf_set_version): Fix spacing.
 728         (upgrade_header): New, in-place header upgrading.
 729         (upgrade_types): Rename to...
 730         (upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No
 731         longer track old and new headers separately.  No longer allow for
 732         header sizes explicitly: squeeze the headers out on upgrade (they
 733         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
 734         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.
 735         (upgrade_types): New, also handle ctf_parmax updating.
 736         (flip_header): Flip ctf_cuname.
 737         (flip_types): Flip BUF explicitly rather than deriving BUF from
 738         BASE.
 739         (ctf_bufopen): Store the header in fp->ctf_header.  Correct minimum
 740         required alignment of objtoff and funcoff.  No longer store it in
 741         the ctf_buf unless that buf is derived unmodified from the input.
 742         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
 743         that duplicate fields in ctf_file: move allocation of ctf_file
 744         further up instead.  Call upgrade_header as needed.  Move
 745         version-specific ctf_parmax initialization into upgrade_types.  More
 746         concise error handling.
 747         (ctf_file_close): No longer test for null pointers before freeing.
 748         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call
 749         ctf_free_base.
 750         (ctf_cuname): New.
 751         (ctf_cuname_set): New.
 752         * ctf-create.c (ctf_update): Populate ctf_cuname.
 753         (ctf_gzwrite): Write out the header explicitly.  Remove obsolescent
 754         comment.
 755         (ctf_write): Likewise.
 756         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
 757         Fix the compression length: fp->ctf_size never counted the CTF
 758         header.  Simplify the compress call accordingly.
 759
 760 2019-07-11  Hans-Peter Nilsson  <hp@bitrange.com>
 761
 762         * ctf-endian.h: Don't assume htole64 and le64toh are always
 763         present if HAVE_ENDIAN_H; also check if htole64 is defined.
 764         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
 765         not bswap_identity_64.

 795         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
 796         Remove member ctf_dtvstrlen: we no longer track the total strlen
 797         as we add strings.

 808         (ctf_file_close): Destroy it.
 809         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
 810         special-case the position of the parname string.  Construct the
 811         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
 812         rest of each buffer element is constructed, not via open-coding:
 813         realloc the CTF buffer and append the strtab to it.  No longer
 814         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
 815         strtab construction.
 816         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
 817         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
 818         after buffer element construction instead.

 862         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
 863         little-endian CTF archive magic.  Do not check the CTF version:
