2694 omitted function argument list.
2696 2006-01-07 Paul Thomas <pault@gcc.gnu.org>
2699 * trans-array.c (gfc_reverse_ss): Remove static attribute.
2700 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
2701 the function call with the corresponding gfc_actual_arglist*. Change
2703 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
2704 now requires the actual argument list instead of the expression for
2706 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
2707 and provide a prototype for gfc_reverse_ss.
2708 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
2709 where an elemental subroutine has array valued actual arguments.
2715 * resolve.c (check_assumed_size_reference): New function to check for upper
2716 bound in assumed size array references.
2717 (resolve_assumed_size_actual): New function to do a very restricted scan
2718 of actual argument expressions of those procedures for which incomplete
2719 assumed size array references are not allowed.
2720 (resolve_function, resolve_call): Switch off assumed size checking of
2721 actual arguments, except for elemental procedures and intrinsic
2722 inquiry functions, in some circumstances.
2723 (resolve_variable): Call check_assumed_size_reference.
2725 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
2728 * io.c (next_char_not_space): New function that returns the next
2729 character that is not white space.
2730 (format_lex): Use the new function to skip whitespace within
2733 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
2736 * expr.c (gfc_expr_set_symbols_referenced): New function.
2737 * gfortran.h: Add a function prototype for it.
2738 * resolve.c (resolve_function): Use it for
2739 use associated character functions lengths.
2740 * expr.c, gfortran.h, resolve.c: Updated copyright years.
2742 2006-01-03 Steven G. Kargl <kargls@comcast.net>
2745 * resolve.c (resolve_forall_iterators): Check for scalar variables;
2746 Check stride is nonzero.
2748 2006-01-02 Steven G. Kargl <kargls@comcast.net>
2751 * parse.c (next_free): Check for whitespace after the label.
2752 * match.c (gfc_match_small_literal_int): Initialize cnt variable.
