--- Comment #13 from Dodji Seketeli <dodji at gcc dot gnu.org> 2011-11-07 21:28:55 UTC --- Author: dodji Date: Mon Nov 7 21:28:50 2011 New Revision: 181118 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=181118 Log: PR c++/45114 - Support C++11 alias-declaration gcc/cp/ * cp-tree.h (TYPE_DECL_ALIAS_P, TYPE_ALIAS_P) (DECL_TYPE_TEMPLATE_P, DECL_ALIAS_TEMPLATE_P): New accessor macros. (TYPE_TEMPLATE_INFO): Get template info of an alias template specializations from its TYPE_DECL. (SET_TYPE_TEMPLATE_INFO): Set template info of alias template specializations into its TYPE_DECL. (DECL_CLASS_TEMPLATE_P): Re-write using the new DECL_TYPE_TEMPLATE_P. (enum cp_decl_spec): Add new ds_alias enumerator. (alias_type_or_template_p, alias_template_specialization_p): Declare new functions. * parser.c (cp_parser_alias_declaration): New static function. (cp_parser_check_decl_spec): Add "using" name for the `alias' declspec. (cp_parser_type_name): Update comment. Support simple-template-id representing alias template specializations in c++0x mode. (cp_parser_qualifying_entity): Update comment. Use cp_parser_type_name. (cp_parser_block_declaration): Handle alias-declaration in c++11. Update comment. (cp_parser_template_id): Handle specializations of alias templates. (cp_parser_member_declaration): Add alias-declaration production to comment. Support alias-declarations. (cp_parser_template_declaration_after_export): Handle alias templates in c++11. * decl.c (make_typename_type, make_unbound_class_template): Accept alias templates. (grokdeclarator): Set TYPE_DECL_ALIAS_P on alias declarations. * decl2.c (grokfield): Move template creation after setting up the TYPE_DECL of the alias, so that the TEMPLATE_DECL of the alias template actually carries the right type-id of the alias declaration. * pt.c (alias_type_or_template_p) (alias_template_specialization_p): Define new public functions. (maybe_process_partial_specialization): Reject partial specializations of alias templates. (primary_template_instantiation_p): Consider alias template instantiations. (push_template_decl_real): Assert that TYPE_DECLs of alias templates are different from those of class template. Store template info onto the TYPE_DECL of the alias template. (convert_template_argument): Strip aliases from template arguments. (lookup_template_class_1): Handle the creation of the specialization of an alias template. (tsubst_decl): Create a substituted copy of the TYPE_DECL of an member alias template. (tsubst): Handle substituting into the type of an alias template. Handle substituting UNBOUND_CLASS_TEMPLATE into BOUND_TEMPLATE_TEMPLATE_PARM. (do_type_instantiation): Better diagnostics when trying to explicitely instantiate a non-class template. * search.c (lookup_field_1, lookup_field_r): Support looking up alias templates. * semantics.c (finish_template_type): For instantiations of alias templates, return the TYPE_DECL of the actual alias and not the one of the aliased type. * error.c (dump_alias_template_specialization): New static function. (dump_type): Handle printing of alias templates and their specializations. templates. (dump_aggr_type): For specialization of alias templates, fetch arguments from the right place. (dump_decl): Print an alias-declaration like `using decl = type;' (dump_template_decl): Support printing of alias templates. gcc/testsuite/ * g++.dg/cpp0x/alias-decl-0.C: New test case. * g++.dg/cpp0x/alias-decl-1.C: Likewise. * g++.dg/cpp0x/alias-decl-3.C: Likewise. * g++.dg/cpp0x/alias-decl-4.C: Likewise. * g++.dg/cpp0x/alias-decl-6.C: Likewise. * g++.dg/cpp0x/alias-decl-7.C: Likewise. * g++.dg/cpp0x/alias-decl-8.C: Likewise. * g++.dg/cpp0x/alias-decl-9.C: Likewise. * g++.dg/cpp0x/alias-decl-10.C: Likewise. * g++.dg/ext/alias-decl-attr1.C: Likewise. * g++.dg/ext/alias-decl-attr2.C: Likewise. * g++.dg/ext/alias-decl-attr3.C: Likewise. * g++.dg/ext/alias-decl-attr4.C: Likewise.
