 667         string.
 668         (ctf_str_add): Adjust accordingly.
 669         (ctf_str_add_ref): Likewise.  Move up in the file.

 673         (ctf_str_write_strtab): If the csa_offset is set, update the
 674         string's refs without writing the string out, and update the

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

 679         Call ctf_simple_open_internal, not ctf_simple_open.

 730         ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
 731         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
 732         ctf_base: do not assume that it is always sizeof (ctf_header_t).
 733         Print out ctf_cuname: only print out ctf_parname if set.
 734         (ctf_free_base): Removed, ctf_base is no longer freed: free
 735         ctf_dynbase instead.
 736         (ctf_set_version): Fix spacing.
 737         (upgrade_header): New, in-place header upgrading.
 738         (upgrade_types): Rename to...
 739         (upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No
 740         longer track old and new headers separately.  No longer allow for
 741         header sizes explicitly: squeeze the headers out on upgrade (they
 742         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
 743         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.
 744         (upgrade_types): New, also handle ctf_parmax updating.
 745         (flip_header): Flip ctf_cuname.
 746         (flip_types): Flip BUF explicitly rather than deriving BUF from
 747         BASE.
 748         (ctf_bufopen): Store the header in fp->ctf_header.  Correct minimum
 749         required alignment of objtoff and funcoff.  No longer store it in
 750         the ctf_buf unless that buf is derived unmodified from the input.
 751         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
 752         that duplicate fields in ctf_file: move allocation of ctf_file
 753         further up instead.  Call upgrade_header as needed.  Move
 754         version-specific ctf_parmax initialization into upgrade_types.  More
 755         concise error handling.
 756         (ctf_file_close): No longer test for null pointers before freeing.
 757         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call
 758         ctf_free_base.
 759         (ctf_cuname): New.
 760         (ctf_cuname_set): New.
 761         * ctf-create.c (ctf_update): Populate ctf_cuname.
 762         (ctf_gzwrite): Write out the header explicitly.  Remove obsolescent
 763         comment.
 764         (ctf_write): Likewise.
 765         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
 766         Fix the compression length: fp->ctf_size never counted the CTF
 767         header.  Simplify the compress call accordingly.
 768
 769 2019-07-11  Hans-Peter Nilsson  <hp@bitrange.com>
 770
 771         * ctf-endian.h: Don't assume htole64 and le64toh are always
 772         present if HAVE_ENDIAN_H; also check if htole64 is defined.
 773         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
 774         not bswap_identity_64.

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

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

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

 880         Remember to copy in the CTF data when opening an uncompressed
 881         foreign-endian CTF file.  Prune useless variable manipulation.
