* dwarf2out.c (debug_pubtypes_section): New static global variable.
(pubname_entry): Add DEF_VEC_O and DEF_VEC_ALLOC_O statements for
this type.
(pubname_table): Redefine as a vector.
(pubtype_table): New static global variable, defined as a vector.
(pubname_table_allocated): Remove static global variable.
(pubname_table_in_use): Remove static global variable.
(PUBNAME_TABLE_INCREMENT): Remove constant.
(size_of_pubnames): Add parameter to deal with either pubnames or
pubtypes, and change code to deal with table being a vector.
(add_pubname): Change to deal with table being a vector.
(add_pubtype): New function.
(output_pubnames): Add parameter to deal with either pubnames or
pubtypes, and change code to deal with table being a vector.
(gen_array_type_die): Add call to add_pubtype.
(gen_enumeration_type_die): Add call to add_pubtype.
(gen_struct_or_union_type_die): Add call to add_pubtype.
(gen_subroutine_type_die): Add call to add_pubtype.
(gen_typedef_die): Add call to add_pubtype.
(dwarf2out_init): Add code to initialize pubname_table and
pubtype_table vectors; also initialize debug_pubtypes_section.
(prune_unused_types): Change to deal with pubnames being a vector.
(dwarf2out_finish): Change to deal with pubnames being a vector; add
pubnames table to call to output_pubnames; Add code to output pubtypes
table if DEBUG_PUBTYPES_SECTION is defined.
* config/darwin.c (darwin_file_start): Add DEBUG_PUBTYPES_SECTION to
debugnames.
* config/darwin.h (DEBUG_PUBTYPES_SECTION): Define new global variable.
