 914         * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
 915         ctf_base: do not assume that it is always sizeof (ctf_header_t).
 916         Print out ctf_cuname: only print out ctf_parname if set.
 917         (ctf_free_base): Removed, ctf_base is no longer freed: free

 921         (upgrade_types): Rename to...

 923         longer track old and new headers separately.  No longer allow for
 924         header sizes explicitly: squeeze the headers out on upgrade (they
 925         are preserved in fp->ctf_header).  Set ctf_dynbase, ctf_base and

 933         the ctf_buf unless that buf is derived unmodified from the input.
 934         Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
 935         that duplicate fields in ctf_file: move allocation of ctf_file
 936         further up instead.  Call upgrade_header as needed.  Move
 937         version-specific ctf_parmax initialization into upgrade_types.  More
 938         concise error handling.
 939         (ctf_file_close): No longer test for null pointers before freeing.
 940         Free ctf_dyncuname, ctf_dynbase, and ctf_header.  Do not call

 948         (ctf_compress_write): Get the header from ctf_header, not ctf_base.
 949         Fix the compression length: fp->ctf_size never counted the CTF
 950         header.  Simplify the compress call accordingly.
 951

 953
 954         * ctf-endian.h: Don't assume htole64 and le64toh are always

 956         [!WORDS_BIGENDIAN] (htole64, le64toh): Define as identity,
