2012-12-19 Paul Thomas <pault@gcc.gnu.org> * array.c (resolve_array_list): Apply C4106. * check.c (gfc_check_same_type_as): Exclude polymorphic entities from check for extensible types. Improved error for disallowed argument types to name the offending type. * class.c : Update copyright date. (gfc_class_null_initializer): Add argument for initialization expression and deal with unlimited polymorphic typespecs. (get_unique_type_string): Give unlimited polymorphic entities a type string. (gfc_intrinsic_hash_value): New function. (gfc_build_class_symbol): Incorporate unlimited polymorphic entities. (gfc_find_derived_vtab): Deal with unlimited polymorphic entities. (gfc_find_intrinsic_vtab): New function. * decl.c (gfc_match_decl_type_spec): Match typespec for unlimited polymorphic type. (gfc_match_data_decl): Skip to 'ok' if unlimited polymorphic. expr.c (gfc_check_pointer_assign): Apply C717. If unlimited polymorphic lvalue, find rvalue vtable for all typespecs, except unlimited polymorphic expressions. (gfc_check_vardef_context): Handle unlimited polymorphic entities. * gfortran.h : Add unlimited polymorphic attribute. Add second arg to gfc_class_null_initializer primitive and primitive for gfc_find_intrinsic_vtab. Add UNLIMITED_POLY to detect unlimited polymorphic expressions. * interface.c (gfc_compare_types): If expr1 is unlimited polymorphic, always return 1. If expr2 is unlimited polymorphic enforce C717. (gfc_compare_interfaces): Skip past conditions that do not apply for unlimited polymorphic entities. (compare_parameter): Make sure that an unlimited polymorphic, allocatable or pointer, formal argument is matched by an unlimited polymorphic actual argument. (compare_actual_formal): Ensure that an intrinsic vtable exists to match an unlimited polymorphic formal argument. * match.c (gfc_match_allocate): Type kind parameter does not need to match an unlimited polymorphic allocate-object. (alloc_opt_list): An unlimited polymorphic allocate-object requires a typespec or a SOURCE tag. (select_intrinsic_set_tmp): New function. (select_type_set_tmp): Call new function. If it returns NULL, build a derived type or class temporary instead. (gfc_match_type_is): Remove restriction to derived types only. Bind(C) or sequence derived types not permitted. * misc (gfc_typename): Printed CLASS(*) for unlimited polymorphism. * module.c : Add AB_UNLIMITED_POLY to pass unlimited polymorphic attribute to and from modules. * resolve.c (resolve_common_vars): Unlimited polymorphic entities cannot appear in common blocks. (resolve_deallocate_expr): Deallocate unlimited polymorphic enities. (resolve_allocate_expr): Likewise for allocation. Make sure vtable exists. (gfc_type_is_extensible): Unlimited polymorphic entities are not extensible. (resolve_select_type): Handle unlimited polymorphic selectors. Ensure that length type parameters are assumed and that names for intrinsic types are generated. (resolve_fl_var_and_proc): Exclude select type temporaries from test of extensibility of type. (resolve_fl_variable): Likewise for test that assumed character length must be a dummy or a parameter. (resolve_fl_derived0): Return SUCCESS unconditionally for unlimited polymorphic entities. Also, allow unlimited polymorphic components. (resolve_fl_derived): Return SUCCESS unconditionally for unlimited polymorphic entities. (resolve_symbol): Return early with unlimited polymorphic entities. * simplifiy.c : Update copyright year. (gfc_simplify_extends_type_of): No simplification possible for unlimited polymorphic arguments. * symbol.c (gfc_use_derived): Nothing to do for unlimited polymorphic "derived type". (gfc_type_compatible): Return unity if ts1 is unlimited polymorphic. * trans-decl.c (create_function_arglist) Formal arguments without a character length should be treated in the same way as passed lengths. (gfc_trans_deferred_vars): Nullify the vptr of unlimited polymorphic pointers. Avoid unlimited polymorphic entities triggering gcc_unreachable. * trans-expr.c (gfc_conv_intrinsic_to_class): New function. (gfc_trans_class_init_assign): Make indirect reference of src.expr. (gfc_trans_class_assign): Expression NULL of unknown type should set NULL vptr on lhs. Treat C717 cases where lhs is a derived type and the rhs is unlimited polymorphic. (gfc_conv_procedure_call): Handle the conversion of a non-class actual argument to match an unlimited polymorphic formal argument. Suppress the passing of a character string length in this case. Make sure that calls to the character __copy function have two character string length arguments. (gfc_conv_initializer): Pass the initialization expression to gfc_class_null_initializer. (gfc_trans_subcomponent_assign): Ditto. (gfc_conv_structure): Move handling of _size component. trans-intrinsic.c: (gfc_conv_same_type_as): Handle conditions where unlimited polymorphic arguments have null vptr. * trans-stmt.c (trans_associate_var): Correctly treat array temporaries associated with unlimited polymorphic selectors. Recover the overwritten dtype for the descriptor. Use the _size field of the vptr for character string lengths. (gfc_trans_allocate): Cope with unlimited polymorphic allocate objects; especially with character source tags. (reset_vptr): New function. (gfc_trans_deallocate): Call it. * trans-types.c (gfc_get_derived_type): Detect unlimited polymorphic types and deal with cases where the derived type of components is null. * trans.c : Update copyright year. (trans_code): Call gfc_trans_class_assign for C717 cases where the lhs is not unlimited polymorphic. 2012-12-19 Paul Thomas <pault@gcc.gnu.org> * intrinsics/extends_type_of.c : Return correct results for null vptrs. 2012-12-19 Paul Thomas <pault@gcc.gnu.org> * gfortran.dg/unlimited_polymorphic_1.f03: New test. * gfortran.dg/unlimited_polymorphic_2.f03: New test. * gfortran.dg/unlimited_polymorphic_3.f03: New test. * gfortran.dg/same_type_as.f03: Correct for improved message.
