PR fortran/21104 * trans.h (gfc_interface_sym_mapping, gfc_interface_mapping): Moved from trans-expr.c. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Declare. * trans-array.h (gfc_set_loop_bounds_from_array_spec): Declare. (gfc_trans_allocate_temp_array): Add pre and post block arguments. * trans-array.c (gfc_set_loop_bounds_from_array_spec): New function. (gfc_trans_allocate_array_storage): Replace loop argument with separate pre and post blocks. (gfc_trans_allocate_temp_array): Add pre and post block arguments. Update call to gfc_trans_allocate_array_storage. (gfc_trans_array_constructor, gfc_conv_loop_setup): Adjust for new interface to gfc_trans_allocate_temp_array. * trans-expr.c (gfc_interface_sym_mapping, gfc_interface_mapping): Moved to trans.h. (gfc_init_interface_mapping, gfc_free_interface_mapping) (gfc_add_interface_mapping, gfc_finish_interface_mapping) (gfc_apply_interface_mapping): Make extern. (gfc_conv_function_call): Build an interface mapping for array return values too. Call gfc_set_loop_bounds_from_array_spec. Adjust call to gfc_trans_allocate_temp_array so that code is added to SE rather than LOOP. From-SVN: r104075
