  30         refs from the vlen on struct deletion.
  31         (ctf_add_struct_sized): Populate the vlen: do it by hand if
  32         promoting forwards.  Always populate the full-size
  33         lsizehi/lsizelo members.

  48         way here.
  49         * ctf-types.c (ctf_member_next): Remove the dmd path and always
  50         use the vlen.  Force large-structure usage for dynamic types.

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

  72         (ctf_add_enumerator): Set up the vlen rather than the dmd.  Expand
  73         it as needed, repointing string refs via ctf_str_move_pending. Add

 343         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 344         name lookup in dynamic dicts without reported symbols, which have

 356         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 357         still cache the dicts those lookups succeed in).  Add
 358         lookup-by-name support, with dicts of successful lookups cached in

 649         (ctf_dump_var): Likewise.
 650         (type_hex_digits): Migrate down in the file, to above its new user.
 651         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 652         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 653         longer generate them.  Dump enumerated types.
