56 (gfc_conv_array_ref): Likewise.
58 2024-03-20 Jakub Jelinek <jakub@redhat.com>
60 * trans-array.cc (structure_alloc_comps): Use integer_zero_node
61 instead of build_zero_cst (integer_type_node) or
62 build_int_cst (integer_type_node, 0) and integer_one_node instead of
63 build_int_cst (integer_type_node, 1).
64 * trans-expr.cc (conv_scalar_char_value): Likewise.

93 associate names, when rank changes or a derived type is
94 produced by resolution
95 * dump-parse-tree.cc (show_code_node): Make output for SELECT
96 TYPE more comprehensible.
97 * expr.cc (find_inquiry_ref): Do not simplify expressions of
99 * gfortran.h : Add 'gfc_association_list' to structure
100 'gfc_association_list'. Add prototypes for
101 'gfc_find_derived_types', 'gfc_fixup_inferred_type_refs' and
102 'gfc_change_class'. Add macro IS_INFERRED_TYPE.
103 * match.cc (copy_ts_from_selector_to_associate): Add bolean arg
104 'select_type' with default false. If this is a select type name

109 * parse.cc (parse_associate): If the selector is inferred type
110 the associate name is too. Make sure that function selector

114 * primary.cc (resolvable_fcns): New function to check that all
115 the function references are resolvable.
116 (gfc_match_varspec): If a scalar derived type select type
117 temporary has an array reference, match the array reference,
118 treating this in the same way as an equivalence member. Do not
119 set 'inquiry' if applied to an unknown type the inquiry name
120 is ambiguous with the component of an accessible derived type.
121 Check that resolution of the target expression is OK by testing
122 if the symbol is declared or is an operator expression, then
123 using 'resolvable_fcns' recursively. If all is well, resolve
124 the expression. If this is an inferred type with a component
125 reference, call 'gfc_find_derived_types' to find a suitable
126 derived type. If there is an inquiry ref and the symbol either
127 is of unknown type or is inferred to be a derived type, set the
128 primary and symbol TKR appropriately.
129 * resolve.cc (resolve_variable): Call new function below.

134 selectors transmit the correct arrayspec to the associate name.
135 (resolve_select_type): If the selector is an associate name of

138 class array to class scalar by calling 'gfc_change_class'.
139 Make sure that a class, inferred type selector with an array
140 ref transfers the typespec from the symbol to the expression.
141 * symbol.cc (gfc_set_default_type): If an associate name with
142 unknown type has a selector expression, try resolving the expr.
143 (find_derived_types, gfc_find_derived_types): New functions
144 that search for a derived type with a given name.
145 * trans-expr.cc (gfc_conv_variable): Some inferred type exprs
146 escape resolution so call 'gfc_fixup_inferred_type_refs'.
147 * trans-stmt.cc (trans_associate_var): Tidy up expression for
148 'class_target'. Finalize and free class function results.

169 (gfc_match_omp_clauses): Add readonly modifier parsing for OpenACC
170 copyin clause, set 'n->u.map.op' and 'n->u.map.readonly' for parsed

236 PDT instance referential access to the typebound procedures
238 * gfortran.h (gfc_pdt_is_instance_of): Add prototype.
239 * resolve.cc (resolve_typebound_procedure): If the derived type
240 does not have the attribute 'pdt_template' set, compare the
241 dummy argument to the 'resolve_bindings_derived' type like usual.
242 If the derived type is a 'pdt_template', then check if the
243 dummy argument is an instance of the PDT template. If the derived
244 type is a PDT template, and the dummy argument is an instance of
245 that template, but the dummy argument 'param_list' is not
246 SPEC_ASSUMED, check if there are any LEN parameters in the
247 dummy argument. If there are no LEN parameters, then this implies
248 that there are only KIND parameters in the dummy argument.
249 If there are LEN parameters, this would be an error, for all
250 LEN parameters for the dummy argument MUST be assumed for
251 typebound procedures of PDTs.
252 (resolve_pdt): Add a check for ALLOCATABLE and POINTER attributes for
253 SPEC_DEFERRED parameters of PDT class symbols. ALLOCATABLE and
254 POINTER attributes for a PDT class symbol are stored in the

256 component respectively.

294 (gfc_trans_subcomponent_assign): Emit se.pre into block
295 before calling alloc_scalar_allocatable_subcomponent instead of
