1561 * resolve.c (resolve_fntype): Check that PUBLIC functions
1562 aren't of PRIVATE type.
1564 2006-01-07 Tobias Schl"uter <tobias.schlueter@physik.uni-muenchen.de>
1566 * decl.c (gfc_match_function_decl): Correctly error out in case of
1567 omitted function argument list.
1569 2006-01-07 Paul Thomas <pault@gcc.gnu.org>
1572 * trans-array.c (gfc_reverse_ss): Remove static attribute.
1573 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
1574 the function call with the corresponding gfc_actual_arglist*. Change
1576 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
1577 now requires the actual argument list instead of the expression for
1579 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
1580 and provide a prototype for gfc_reverse_ss.
1581 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
1582 where an elemental subroutine has array valued actual arguments.
1588 * resolve.c (check_assumed_size_reference): New function to check for upper
1589 bound in assumed size array references.
1590 (resolve_assumed_size_actual): New function to do a very restricted scan
1591 of actual argument expressions of those procedures for which incomplete
1592 assumed size array references are not allowed.
1593 (resolve_function, resolve_call): Switch off assumed size checking of
1594 actual arguments, except for elemental procedures and intrinsic
1595 inquiry functions, in some circumstances.
1596 (resolve_variable): Call check_assumed_size_reference.
1598 2006-01-05 Jerry DeLisle <jvdelisle@gcc.gnu.org>
1601 * io.c (next_char_not_space): New function that returns the next
1602 character that is not white space.
1603 (format_lex): Use the new function to skip whitespace within
1606 2006-01-05 Erik Edelmann <eedelman@gcc.gnu.org>
1609 * expr.c (gfc_expr_set_symbols_referenced): New function.
1610 * gfortran.h: Add a function prototype for it.
1611 * resolve.c (resolve_function): Use it for
1612 use associated character functions lengths.
1613 * expr.c, gfortran.h, resolve.c: Updated copyright years.
1615 2006-01-03 Steven G. Kargl <kargls@comcast.net>
1618 * resolve.c (resolve_forall_iterators): Check for scalar variables;
1619 Check stride is nonzero.
1621 2006-01-02 Steven G. Kargl <kargls@comcast.net>
1624 * parse.c (next_free): Check for whitespace after the label.
1625 * match.c (gfc_match_small_literal_int): Initialize cnt variable.
