1586 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
1589 * trans-types.c (gfc_get_derived_type): Check for the
1590 presence of derived->ns->proc_name before
1591 accessing derived->ns->proc_name->attr.flavor .
1592 * resolve.c (resolve_symbol): Likewise.
1594 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
1597 * gfortran.h : Add bit to gfc_expr 'user_operator'
1598 * interface.c (gfc_extend_expr): Set the above if the operator
1599 is substituted by a function.
1600 * resolve.c (check_host_association): Return if above is set.
1602 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1605 * ChangeLog-2008: Fix function name.
1608 * dependency.c (gfc_check_argument_var_dependency):
1609 Move the check for pointerness inside the if block
1610 so that it doesn't affect the return value.
1613 * trans-stmt.c (gfc_trans_call):
1614 Add the dependency code after the loop bounds calculation one.
1616 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
1618 * intrinsic.c (do_simplify): Removed already implemented TODO.
1620 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
1623 * simplify.c (gfc_simplify_merge): New.
1624 * intrinsic.h (gfc_simplify_merge): New prototype.
1625 * intrinsic.c (add_functions): Added simplification for MERGE.
1627 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1630 * gfortran.h (gfc_is_data_pointer): Added prototype
1631 * resolve.c (gfc_iso_c_func_interface):
1632 Use gfc_is_data_pointer to test for pointer attribute.
1633 * dependency.c (gfc_is_data_pointer):
1634 Support pointer-returning functions.
1636 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
1638 * symbol.c (save_symbol): Don't SAVE function results.
1640 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
1643 * resolve.c (resolve_call): When searching for proper host
1644 association, use symtree rather than symbol. For everything
1645 except generic subroutines, substitute the symtree in the call
1646 rather than the symbol.
