 660         * configure.ac (BFD_LIBADD): Remove.
 661         (BFD_DEPENDENCIES): Likewise. Remove associated cases.
 662         (SHARED_LIBADD): Rename to...
 663         (CTF_LIBADD): ... this.  Stick in a suitable libiberty even when
 664         linking statically.
 665         * Makefile.am (libctf_nobfd_la_LIBADD): Adjust accordingly.
 666         libctf uses libintl.
 667         (libctf_la_LIBADD): Reference libbfd.la directly, not via
 668         BFD_LIBADD.
 669         (libctf_la_DEPENDENCIES): Remove.
 670         * Makefile.in: Regenerate.

 676         * ctf-types.c (ctf_type_aname): No longer deal with slices here.
 677         * ctf-dump.c (ctf_dump_membstate_t) <cdm_toplevel_indent>: Constify.
 678         (CTF_FT_REFS): New.

 680         (CTF_FT_ID): Likewise.
 681         (ctf_dump_member): Do not do indentation here. Migrate the
 682         type-printing parts of this into...
 683         (ctf_dump_format_type): ... here, to be shared by all type printers.
 684         Get the errno value for non-representable types right.  Do not print
 685         bitfield info for non-bitfields.  Improve the format and indentation
 686         of other type output.  Shuffle spacing around to make all indentation
 687         either 'width of column' or 4 chars.
 688         (ctf_dump_label): Pass CTF_FT_REFS to ctf_dump_format_type.
 689         (ctf_dump_objts): Likewise.  Spacing shuffle.
 690         (ctf_dump_var): Likewise.
 691         (type_hex_digits): Migrate down in the file, to above its new user.
 692         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 693         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 694         longer generate them.  Dump enumerated types.

 699         (ctf_type_size): Yield ECTF_INCOMPLETE when applied to forwards.
 700         Emit errors into the right dict.
 701         (ctf_type_align): Likewise.
 702         * ctf-create.c (ctf_add_member_offset): Yield ECTF_INCOMPLETE
 703         when adding a member without explicit offset when this member, or
 704         the previous member, is incomplete.
 705         * ctf-dump.c (ctf_dump_format_type): Do not try to print the size of
 706         forwards.
 707         (ctf_dump_member): Do not try to print their alignment.

 712         (ctf_dump_format_type): Don't emit the size for function objects.
 713         Dump the element type of arrays like we dump the pointed-to type of
 714         pointers, etc.

 719         (ctf_dump_header): Add 0x to the hex magic number.
 720         (ctf_dump_str): Add 0x to the hex string offsets.
 721         (ctf_dump_membstate_t) <cdm_toplevel_indent>: New.
 722         (ctf_dump_type): Adjust.  Free it when we're done.
 723         (type_hex_digits): New.
 724         (ctf_dump_member): Align output depending on the width of the type
 725         ID being generated.  Use printf padding, not a loop, to generate
 726         indentation.
