   2
   3         * ctf-impl.h (ctf_dtdef_t) <dtd_vlen_alloc>: New.
   4         (ctf_str_move_pending): Declare.
   5         * ctf-string.c (ctf_str_add_ref_internal): Fix error return.
   6         (ctf_str_move_pending): New.
   7         * ctf-create.c (ctf_grow_vlen): New.
   8         (ctf_dtd_delete): Zero out the vlen_alloc after free.  Free the
   9         vlen later: iterate over it and free enum name refs first.
  10         (ctf_add_generic): Populate dtd_vlen_alloc from vlen.
  11         (ctf_add_enum): populate the vlen; do it by hand if promoting
  12         forwards.
  13         (ctf_add_enumerator): Set up the vlen rather than the dmd.  Expand
  14         it as needed, repointing string refs via ctf_str_move_pending. Add
  15         the enumerand names as pending strings.
  16         * ctf-serialize.c (ctf_copy_emembers): Remove.
  17         (ctf_emit_type_sect): Copy the vlen into place and ref the
  18         strings.
  19         * ctf-types.c (ctf_enum_next): The dynamic portion now uses
  20         the same code as the non-dynamic.
  21         (ctf_enum_name): Likewise.
  22         (ctf_enum_value): Likewise.
  23         * testsuite/libctf-lookup/enum-many-ctf.c: New test.

  40         (ctf_str_add_external): Likewise.

  42         (ctf_str_remove_ref): Also remove the potential ref if it is a
  43         pending ref.
  44         * ctf-serialize.c (ctf_serialize): Prohibit addition of strings
  45         with ctf_str_add_ref before serialization.  Ensure that the
  46         ctf_str_pending_ref set is empty before strtab finalization.
  47         (ctf_emit_type_sect): Add a ref to the ctt_name.
  48         * ctf-create.c (ctf_add_generic): Add the ctt_name as a pending

 283         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
 284         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 285         name lookup in dynamic dicts without reported symbols, which have
 286         no symtab or dynsymidx but where name lookup should still work.
 287         (ctf_lookup_by_symbol_name): New, another wrapper.
 288         * ctf-archive.c (enosym): Note that this is present in

 296         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
 297         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 298         still cache the dicts those lookups succeed in).  Add
 299         lookup-by-name support, with dicts of successful lookups cached in
 300         ctfi_symnamedicts.  Refactor the caching code a bit.
 301         (ctf_arc_lookup_symbol_name): New, another wrapper.
 302         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.

 305         * testsuite/libctf-lookup/enum-symbol.c (main): Use
 306         ctf_arc_lookup_symbol rather than looking up the name ourselves.
 307         Fish it out repeatedly, to make sure that symbol caching isn't
 308         broken.
 309         (symidx_64): Remove.
 310         (symidx_32): Remove.
 311         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
 312         in an unlinked object file (indexed symtypetab sections only).
