  46         (ctf_add_struct_sized): Populate the vlen: do it by hand if
  47         promoting forwards.  Always populate the full-size

  85         (ctf_add_enum): populate the vlen; do it by hand if promoting

  87         (ctf_add_enumerator): Set up the vlen rather than the dmd.  Expand
  88         it as needed, repointing string refs via ctf_str_move_pending. Add
  89         the enumerand names as pending strings.

 653         (CTF_FT_BITFIELD): Likewise.
 654         (CTF_FT_ID): Likewise.
 655         (ctf_dump_member): Do not do indentation here. Migrate the
 656         type-printing parts of this into...
 657         (ctf_dump_format_type): ... here, to be shared by all type printers.
 658         Get the errno value for non-representable types right.  Do not print
 659         bitfield info for non-bitfields.  Improve the format and indentation
 660         of other type output.  Shuffle spacing around to make all indentation
 661         either 'width of column' or 4 chars.
 662         (ctf_dump_label): Pass CTF_FT_REFS to ctf_dump_format_type.
 663         (ctf_dump_objts): Likewise.  Spacing shuffle.
 664         (ctf_dump_var): Likewise.
 665         (type_hex_digits): Migrate down in the file, to above its new user.
 666         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 667         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 668         longer generate them.  Dump enumerated types.

 676         * ctf-create.c (ctf_add_member_offset): Yield ECTF_INCOMPLETE
 677         when adding a member without explicit offset when this member, or
 678         the previous member, is incomplete.
 679         * ctf-dump.c (ctf_dump_format_type): Do not try to print the size of
 680         forwards.

 687         Dump the element type of arrays like we dump the pointed-to type of
 688         pointers, etc.

 698         (ctf_dump_member): Align output depending on the width of the type
 699         ID being generated.  Use printf padding, not a loop, to generate
 700         indentation.
