1586 2009-01-05 Daniel Franke <franke.daniel@gmail.com>
1589 * check.c (gfc_check_random_seed): Added size check for GET
1590 dummy argument, reworded error messages to follow common pattern.
1592 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
1595 * trans-types.c (gfc_get_derived_type): Check for the
1596 presence of derived->ns->proc_name before
1597 accessing derived->ns->proc_name->attr.flavor .
1598 * resolve.c (resolve_symbol): Likewise.
1600 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
1603 * gfortran.h : Add bit to gfc_expr 'user_operator'
1604 * interface.c (gfc_extend_expr): Set the above if the operator

1606 * resolve.c (check_host_association): Return if above is set.
1608 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1611 * ChangeLog-2008: Fix function name.
1614 * dependency.c (gfc_check_argument_var_dependency):
1615 Move the check for pointerness inside the if block
1616 so that it doesn't affect the return value.
1619 * trans-stmt.c (gfc_trans_call):
1620 Add the dependency code after the loop bounds calculation one.
1622 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
1624 * intrinsic.c (do_simplify): Removed already implemented TODO.

1636 * gfortran.h (gfc_is_data_pointer): Added prototype
1637 * resolve.c (gfc_iso_c_func_interface):
1638 Use gfc_is_data_pointer to test for pointer attribute.
1639 * dependency.c (gfc_is_data_pointer):
1640 Support pointer-returning functions.
1642 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
1644 * symbol.c (save_symbol): Don't SAVE function results.
1646 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
1649 * resolve.c (resolve_call): When searching for proper host
1650 association, use symtree rather than symbol. For everything
1651 except generic subroutines, substitute the symtree in the call
1652 rather than the symbol.
