+ * ctf-impl.h (ctf_dtdef_t) <dtu_members>: Remove.
+ <dtd_u>: Likewise.
+ (ctf_dmdef_t): Remove.
+ (struct ctf_next) <u.ctn_dmd>: Remove.
+ * ctf-create.c (INITIAL_VLEN): New, more-or-less arbitrary initial
+ vlen size.
+ (ctf_add_enum): Use it.
+ (ctf_dtd_delete): Do not free the (removed) dmd; remove string
+ refs from the vlen on struct deletion.
+ (ctf_add_struct_sized): Populate the vlen: do it by hand if
+ promoting forwards. Always populate the full-size
+ lsizehi/lsizelo members.
+ (ctf_add_union_sized): Likewise.
+ (ctf_add_member_offset): Set up the vlen rather than the dmd.
+ Expand it as needed, repointing string refs via
+ ctf_str_move_pending. Add the member names as pending strings.
+ Always populate the full-size lsizehi/lsizelo members.
+ (membadd): Remove, folding back into...
+ (ctf_add_type_internal): ... here, adding via an ordinary
+ ctf_add_struct_sized and _next iteration rather than doing
+ everything by hand.
+ * ctf-serialize.c (ctf_copy_smembers): Remove this...
+ (ctf_copy_lmembers): ... and this...
+ (ctf_emit_type_sect): ... folding into here. Figure out if a
+ ctf_stype_t is needed here, not in ctf_add_*_sized.
+ (ctf_type_sect_size): Figure out the ctf_stype_t stuff the same
+ way here.
+ * ctf-types.c (ctf_member_next): Remove the dmd path and always
+ use the vlen. Force large-structure usage for dynamic types.
+ (ctf_type_align): Likewise.
+ (ctf_member_info): Likewise.
+ (ctf_type_rvisit): Likewise.
+ * testsuite/libctf-regression/type-add-unnamed-struct-ctf.c: Add a
+ self-referential type to this test.
+ * testsuite/libctf-regression/type-add-unnamed-struct.c: Adjusted
