2693 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
2694 now requires the actual argument list instead of the expression for
2696 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
2697 and provide a prototype for gfc_reverse_ss.
2698 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
2699 where an elemental subroutine has array valued actual arguments.
2705 * resolve.c (check_assumed_size_reference): New function to check for upper
2706 bound in assumed size array references.
2707 (resolve_assumed_size_actual): New function to do a very restricted scan
2708 of actual argument expressions of those procedures for which incomplete
2709 assumed size array references are not allowed.
2710 (resolve_function, resolve_call): Switch off assumed size checking of
2711 actual arguments, except for elemental procedures and intrinsic
2712 inquiry functions, in some circumstances.
2713 (resolve_variable): Call check_assumed_size_reference.
2715 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
2718 * io.c (next_char_not_space): New function that returns the next
2719 character that is not white space.
2720 (format_lex): Use the new function to skip whitespace within
2723 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
2726 * expr.c (gfc_expr_set_symbols_referenced): New function.
2727 * gfortran.h: Add a function prototype for it.
2728 * resolve.c (resolve_function): Use it for
2729 use associated character functions lengths.
2730 * expr.c, gfortran.h, resolve.c: Updated copyright years.
2732 2006-01-03 Steven G. Kargl <kargls@comcast.net>

2736 Check stride is nonzero.
