1583 * symbol.c (generate_isocbinding_symbol): Mark c_loc and
1586 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
1589 * module.c (write_common_0): Use the name of the symtree rather
1590 than the common block, to determine if the common has been
1593 2009-01-05 Daniel Franke <franke.daniel@gmail.com>
1596 * check.c (gfc_check_random_seed): Added size check for GET
1597 dummy argument, reworded error messages to follow common pattern.
1599 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
1602 * trans-types.c (gfc_get_derived_type): Check for the
1603 presence of derived->ns->proc_name before
1604 accessing derived->ns->proc_name->attr.flavor .
1605 * resolve.c (resolve_symbol): Likewise.
1607 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
1610 * gfortran.h : Add bit to gfc_expr 'user_operator'
1611 * interface.c (gfc_extend_expr): Set the above if the operator
1612 is substituted by a function.
1613 * resolve.c (check_host_association): Return if above is set.
1615 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1618 * ChangeLog-2008: Fix function name.
1621 * dependency.c (gfc_check_argument_var_dependency):
1622 Move the check for pointerness inside the if block
1623 so that it doesn't affect the return value.
1626 * trans-stmt.c (gfc_trans_call):
1627 Add the dependency code after the loop bounds calculation one.
1629 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
1631 * intrinsic.c (do_simplify): Removed already implemented TODO.
1633 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
1636 * simplify.c (gfc_simplify_merge): New.
1637 * intrinsic.h (gfc_simplify_merge): New prototype.
1638 * intrinsic.c (add_functions): Added simplification for MERGE.
1640 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1643 * gfortran.h (gfc_is_data_pointer): Added prototype
1644 * resolve.c (gfc_iso_c_func_interface):
1645 Use gfc_is_data_pointer to test for pointer attribute.
1646 * dependency.c (gfc_is_data_pointer):
1647 Support pointer-returning functions.
1649 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
1651 * symbol.c (save_symbol): Don't SAVE function results.
1653 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
1656 * resolve.c (resolve_call): When searching for proper host
1657 association, use symtree rather than symbol. For everything
1658 except generic subroutines, substitute the symtree in the call
1659 rather than the symbol.
