2613 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2616 * module.c (write_common_0): Use the name of the symtree rather

2620 2009-01-05 Daniel Franke <franke.daniel@gmail.com>
2623 * check.c (gfc_check_random_seed): Added size check for GET
2624 dummy argument, reworded error messages to follow common pattern.
2626 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2629 * trans-types.c (gfc_get_derived_type): Check for the
2630 presence of derived->ns->proc_name before
2631 accessing derived->ns->proc_name->attr.flavor .
2632 * resolve.c (resolve_symbol): Likewise.
2634 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2637 * gfortran.h : Add bit to gfc_expr 'user_operator'
2638 * interface.c (gfc_extend_expr): Set the above if the operator
2639 is substituted by a function.
2640 * resolve.c (check_host_association): Return if above is set.
2642 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2645 * ChangeLog-2008: Fix function name.
2648 * dependency.c (gfc_check_argument_var_dependency):
2649 Move the check for pointerness inside the if block
2650 so that it doesn't affect the return value.
2653 * trans-stmt.c (gfc_trans_call):
2654 Add the dependency code after the loop bounds calculation one.
2656 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2658 * intrinsic.c (do_simplify): Removed already implemented TODO.

2667 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2670 * gfortran.h (gfc_is_data_pointer): Added prototype
2671 * resolve.c (gfc_iso_c_func_interface):
2672 Use gfc_is_data_pointer to test for pointer attribute.
2673 * dependency.c (gfc_is_data_pointer):
2674 Support pointer-returning functions.
2676 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
2678 * symbol.c (save_symbol): Don't SAVE function results.
2680 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
2683 * resolve.c (resolve_call): When searching for proper host
2684 association, use symtree rather than symbol. For everything
2685 except generic subroutines, substitute the symtree in the call
2686 rather than the symbol.
