4372 2006-01-08 Erik Edelmann <eedelman@gcc.gnu.org>
4375 * resolve.c (resolve_fntype): Check that PUBLIC functions

4380 * decl.c (gfc_match_function_decl): Correctly error out in case of
4381 omitted function argument list.
4383 2006-01-07 Paul Thomas <pault@gcc.gnu.org>
4386 * trans-array.c (gfc_reverse_ss): Remove static attribute.
4387 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
4388 the function call with the corresponding gfc_actual_arglist*. Change
4390 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
4391 now requires the actual argument list instead of the expression for
4393 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
4394 and provide a prototype for gfc_reverse_ss.
4395 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
4396 where an elemental subroutine has array valued actual arguments.
4402 * resolve.c (check_assumed_size_reference): New function to check for upper
4403 bound in assumed size array references.
4404 (resolve_assumed_size_actual): New function to do a very restricted scan
4405 of actual argument expressions of those procedures for which incomplete
4406 assumed size array references are not allowed.
4407 (resolve_function, resolve_call): Switch off assumed size checking of
4408 actual arguments, except for elemental procedures and intrinsic
4409 inquiry functions, in some circumstances.
4410 (resolve_variable): Call check_assumed_size_reference.
4412 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
4415 * io.c (next_char_not_space): New function that returns the next
4416 character that is not white space.
4417 (format_lex): Use the new function to skip whitespace within
4420 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
4423 * expr.c (gfc_expr_set_symbols_referenced): New function.
4424 * gfortran.h: Add a function prototype for it.
4425 * resolve.c (resolve_function): Use it for
4426 use associated character functions lengths.
4427 * expr.c, gfortran.h, resolve.c: Updated copyright years.
4429 2006-01-03 Steven G. Kargl <kargls@comcast.net>
4432 * resolve.c (resolve_forall_iterators): Check for scalar variables;
4433 Check stride is nonzero.
4435 2006-01-02 Steven G. Kargl <kargls@comcast.net>
4438 * parse.c (next_free): Check for whitespace after the label.
4439 * match.c (gfc_match_small_literal_int): Initialize cnt variable.
