1131 in the call to the component's finalizer wrapper.
1132 (has_finalizer_component): Do not return true for procedure

1135 in the call to the final subroutine.

1141 * resolve.cc (resolve_function): Correct derived types that
1142 have an incomplete namespace.
1143 (resolve_where, gfc_resolve_where_code_in_forall,
1144 gfc_resolve_forall_body, gfc_resolve_code): Check that the op
1145 code is still EXEC_ASSIGN. If it is set lhs to must finalize.

1147 (generate_component_assignments): Set must_finalize if needed.
1148 (gfc_resolve_finalizers): Error if assumed rank finalizer is
1149 not the only one. Warning on lack of scalar finalizer modified

1151 (generate_final_call): New function.
1152 (generate_component_assignments): Enclose the outermost call in
1153 a block to capture automatic deallocation and final calls.
1154 Set must_finalize as required to satisfy the standards. Use an
1155 explicit pointer assignment for pointer components to capture
1156 finalization of the target. Likewise use explicit assignment
1157 for allocatable components. Do not use the temporary copy of
1158 the lhs in defined assignment if the component is allocatable.
1159 Put the temporary in the same namespace as the lhs symbol if
1160 the component may be finalized. Remove the leading assignment
1161 from the expansion of assignment of components that have their
1162 own defined assignment components. Suppress finalization of
1163 assignment of temporary components to the lhs. Make an explicit
1164 final call for the rhs function temporary if it exists.

1166 array constructor on the rhs.
1167 (gfc_resolve_finalizers): Ensure that an assumed rank finalizer

1173 (resolve_symbol): Set referenced an unreferenced symbol that
1175 * trans-array.cc (gfc_trans_array_constructor_value): Add code
1176 to finalize the constructor result. Warn that this feature was
1177 removed in F2018 and that it is suppressed by -std=2018.
1178 (trans_array_constructor): Add finalblock, pass to previous
1179 and apply to loop->post if filled.
1180 (gfc_add_loop_ss_code): Add se finalblock to outer loop post.
1181 (gfc_trans_array_cobounds, gfc_trans_array_bounds): Add any
1182 generated finalization code to the main block.
1183 (structure_alloc_comps): Add boolean argument to suppress
1184 finalization and use it for calls from
1185 gfc_deallocate_alloc_comp_no_caf. Otherwise it defaults to
1187 (gfc_copy_alloc_comp_no_fini): New wrapper for
1188 structure_alloc_comps.
1189 (gfc_alloc_allocatable_for_assignment): Suppress finalization
1190 by setting new arg in call to gfc_deallocate_alloc_comp_no_caf.
1191 (gfc_trans_deferred_array): Use gfc_may_be_finalized and do not
1192 deallocate the components of entities with a leading '_' in the
1193 name that are also marked as artificial.

1195 of gfc_deallocate_alloc_comp_no_caf with a default of false.
1196 Add prototype for gfc_copy_alloc_comp_no_fini.

1198 * trans-expr.cc (gfc_init_se): Initialize finalblock.
1199 (gfc_conv_procedure_call): Use gfc_finalize_tree_expr to
1200 finalize function results. Replace in-line block for class
1201 results with call to new function.
1202 (gfc_conv_expr): Finalize structure constructors for F2003 and
1203 F2008. Warn that this feature was deleted in F2018 and, unlike
1204 array constructors, is not default. Add array constructor
1205 finalblock to the post block.
1206 (gfc_trans_scalar_assign): Suppress finalization by setting new
1207 argument in call to gfc_deallocate_alloc_comp_no_caf. Add the
1208 finalization blocks to the main block.
1209 (gfc_trans_arrayfunc_assign): Use gfc_assignment_finalizer_call
1210 and ensure that finalization occurs after the evaluation of the
1211 rhs but using the initial value for the lhs. Finalize rhs
1212 function results using gfc_finalize_tree_expr.
1213 (trans_class_assignment, gfc_trans_assignment_1): As previous
1214 function, taking care to order evaluation, assignment and
1215 finalization correctly.
1216 * trans-io.cc (gfc_trans_transfer): Add the final block.
1217 * trans-stmt.cc (gfc_trans_call, gfc_trans_allocate): likewise.
1218 (trans_associate_var): Nullify derived allocatable components
1219 and finalize function targets with defined assignment
1220 components on leaving the block scope.
1221 (trans_allocate): Finalize source expressions, if required,
1222 and set init_expr artificial temporarily to suppress the
1223 finalization in gfc_trans_assignment.
1224 * trans.cc (gfc_add_finalizer_call): Do not finalize the
1225 temporaries generated in type assignment with defined
1226 assignment components.

1228 (gfc_finalize_tree_expr): New function.
