Implement noexcept-specification (15.4)
Implement noexcept-specification (15.4)
* parser.c (cp_parser_exception_specification_opt): Parse it.
Give -Wdeprecated warning about throw() specs.
* pt.c (tsubst_exception_specification): Handle it.
* error.c (dump_exception_spec): Handle it.
* cxx-pretty-print.c (pp_cxx_exception_specification): Likewise.
* typeck.c (comp_except_specs): Handle compatibility rules.
Change exact parm to take an enum.
* typeck2.c (merge_exception_specifiers): Handle noexcept.
* except.c (nothrow_spec_p, type_noexcept_p): New fns.
(type_throw_all_p, build_noexcept_spec): New fns.
* cp-tree.h (TYPE_NOTHROW_P, TYPE_NOEXCEPT_P): Use them.
(comp_except_specs): Define ce_derived, ce_normal, ce_exact enums.
(cp_tree_index): Add CPTI_NOEXCEPT_TRUE_SPEC, CPTI_NOEXCEPT_FALSE_SPEC.
(noexcept_true_spec, noexcept_false_spec): New macros.
* name-lookup.c (pushdecl_maybe_friend): Adjust.
* search.c (check_final_overrider): Adjust.
* decl.c (check_redeclaration_exception_specification): Adjust.
(use_eh_spec_block): Use type_throw_all_p.
(cxx_init_decl_processing): Set noexcept_false_spec,noexcept_true_spec.
Give operator new a noexcept-specification in C++0x mode.
* tree.c (build_exception_variant, cxx_type_hash_eq): Adjust.
(cp_build_type_attribute_variant): Don't test TYPE_RAISES_EXCEPTIONS.
