  36         refs from the vlen on struct deletion.
  37         (ctf_add_struct_sized): Populate the vlen: do it by hand if
  38         promoting forwards.  Always populate the full-size

  76         (ctf_add_enum): populate the vlen; do it by hand if promoting
  77         forwards.
  78         (ctf_add_enumerator): Set up the vlen rather than the dmd.  Expand
  79         it as needed, repointing string refs via ctf_str_move_pending. Add
  80         the enumerand names as pending strings.
  81         * ctf-serialize.c (ctf_copy_emembers): Remove.

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

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