(external_die_map): New global. (lookup_decl_die): When in LTO create DIEs lazily from the external_die_map. (lookup_block_die): New function, create DIEs lazily in LTO. (equate_block_to_die): New function. (dwarf2out_die_ref_for_decl): During WPA get the association from the external DIE map. (dwarf2out_register_external_die): Record mapping into the external DIE map. (maybe_create_die_with_external_ref): New function split out from DIE generation part of old dwarf2out_register_external_die. (add_abstract_origin_attribute): Do not return the DIE. When in LTO reference externals directly. (dwarf2out_abstract_function): When in LTO ignore calls for decls with external DIEs (already present abstract instances). (gen_call_site_die): Adjust. (add_high_low_attributes): Likewise. (gen_lexical_block_die): Likewise. (gen_inlined_subroutine_die): Likewie. (gen_block_die): Likewise. (dwarf2out_inline_entry): Likewise. (dwarf2out_early_finish): In LTRANS phase create DW_TAG_imported_unit DIEs. Modified: trunk/gcc/ChangeLog trunk/gcc/dwarf2out.c
