Check that the dummy and the actual argument are both optional, and set can_be_null_ref accordingly. 2012-01-04 Mikael Morin <mikael@gcc.gnu.org> PR fortran/50981 * trans.h (struct gfc_ss_info): New field data::scalar::can_be_null_ref * trans-array.c: If the reference can be NULL, save the reference instead of the value. * trans-expr.c (gfc_conv_expr): If we have saved a reference, dereference it. 2012-01-04 Mikael Morin <mikael@gcc.gnu.org> * trans-expr.c (gfc_conv_expr): Move address taking...

PR fortran/46262 PR fortran/46328 PR fortran/51052 * interface.c(build_compcall_for_operator): Add a type to the expression. * trans-expr.c (conv_base_obj_fcn_val): New function. (gfc_conv_procedure_call): Use base_expr to detect non-variable base objects and, ensuring that there is a temporary variable, build up the typebound call using conv_base_obj_fcn_val. (gfc_trans_class_assign): Pick out class procedure pointer assignments and do the assignment with no further prcessing. (gfc_trans_class_array_init_assign, gfc_trans_class_init_assign gfc_trans_class_assign): Move to top of file. * gfortran.h : Add 'base_expr' field to gfc_expr. * resolve.c (get_declared_from_expr): Add 'types' argument to switch checking of derived types on or off. (resolve_typebound_generic_call): Set the new argument. (resolve_typebound_function, resolve_typebound_subroutine): Set 'types' argument for get_declared_from_expr appropriately. Identify base expression, if not a variable, in the argument list of class valued calls. Assign it to the 'base_expr' field of the final expression. Strip away all references after the last class reference. 2012-01-02 Tobias Burnus <burnus@net-b.de> PR fortran/51682 * trans-intrinsic.c (trans_this_image, trans_image_index, trans_num_images, conv_intrinsic_cobound): Fold_convert the caf_num_images/caf_this_images variables to the correct int kind. 2012-01-01 Jakub Jelinek <jakub@redhat.com> * gfortranspec.c (lang_specific_driver): Update copyright notice dates.
