  21         (ctf_add_enum): Use it.
  22         (ctf_dtd_delete): Do not free the (removed) dmd; remove string
  23         refs from the vlen on struct deletion.
  24         (ctf_add_struct_sized): Populate the vlen: do it by hand if
  25         promoting forwards.  Always populate the full-size
  26         lsizehi/lsizelo members.

  32         (membadd): Remove, folding back into...
  33         (ctf_add_type_internal): ... here, adding via an ordinary

  37         (ctf_copy_lmembers): ... and this...
  38         (ctf_emit_type_sect): ... folding into here. Figure out if a
  39         ctf_stype_t is needed here, not in ctf_add_*_sized.
  40         (ctf_type_sect_size): Figure out the ctf_stype_t stuff the same
  41         way here.
  42         * ctf-types.c (ctf_member_next): Remove the dmd path and always
  43         use the vlen.  Force large-structure usage for dynamic types.
  44         (ctf_type_align): Likewise.

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

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

 646         longer generate them.  Dump enumerated types.

 658         forwards.

 664         (ctf_dump_format_type): Don't emit the size for function objects.
 665         Dump the element type of arrays like we dump the pointed-to type of
