 764         ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
 765         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
 766         ctf_base: do not assume that it is always sizeof (ctf_header_t).
 767         Print out ctf_cuname: only print out ctf_parname if set.
 768         (ctf_free_base): Removed, ctf_base is no longer freed: free
 769         ctf_dynbase instead.
 770         (ctf_set_version): Fix spacing.
 771         (upgrade_header): New, in-place header upgrading.
 772         (upgrade_types): Rename to...
 773         (upgrade_types_v1): ... this.  Free ctf_dynbase, not ctf_base.  No
 774         longer track old and new headers separately.  No longer allow for
 775         header sizes explicitly: squeeze the headers out on upgrade (they
 776         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and
 777         ctf_buf explicitly.  Use ctf_free, not ctf_free_base.
 778         (upgrade_types): New, also handle ctf_parmax updating.
 779         (flip_header): Flip ctf_cuname.
 780         (flip_types): Flip BUF explicitly rather than deriving BUF from
 781         BASE.
 782         (ctf_bufopen): Store the header in fp->ctf_header.  Correct minimum
 783         required alignment of objtoff and funcoff.  No longer store it in
 784         the ctf_buf unless that buf is derived unmodified from the input.
 785         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
 786         that duplicate fields in ctf_file: move allocation of ctf_file
 787         further up instead.  Call upgrade_header as needed.  Move
 788         version-specific ctf_parmax initialization into upgrade_types.  More
 789         concise error handling.
 790         (ctf_file_close): No longer test for null pointers before freeing.
 791         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call
 792         ctf_free_base.
 793         (ctf_cuname): New.
 794         (ctf_cuname_set): New.
 795         * ctf-create.c (ctf_update): Populate ctf_cuname.
 796         (ctf_gzwrite): Write out the header explicitly.  Remove obsolescent
 797         comment.
 798         (ctf_write): Likewise.
 799         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
 800         Fix the compression length: fp->ctf_size never counted the CTF
 801         header.  Simplify the compress call accordingly.
 802
 803 2019-07-11  Hans-Peter Nilsson  <hp@bitrange.com>
 804
 805         * ctf-endian.h: Don't assume htole64 and le64toh are always
 806         present if HAVE_ENDIAN_H; also check if htole64 is defined.
 807         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
 808         not bswap_identity_64.

 839         Remove member ctf_dtvstrlen: we no longer track the total strlen
 840         as we add strings.

 851         (ctf_file_close): Destroy it.
 852         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
 853         special-case the position of the parname string.  Construct the
 854         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
 855         rest of each buffer element is constructed, not via open-coding:
 856         realloc the CTF buffer and append the strtab to it.  No longer
 857         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
 858         strtab construction.
 859         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
 860         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref
 861         after buffer element construction instead.

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