1076 * check.c (gfc_check_random_seed): Added size check for GET
1077 dummy argument, reworded error messages to follow common pattern.
1079 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
1082 * trans-types.c (gfc_get_derived_type): Check for the
1083 presence of derived->ns->proc_name before
1084 accessing derived->ns->proc_name->attr.flavor .
1085 * resolve.c (resolve_symbol): Likewise.
1087 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
1090 * gfortran.h : Add bit to gfc_expr 'user_operator'
1091 * interface.c (gfc_extend_expr): Set the above if the operator

1095 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
1098 * ChangeLog-2008: Fix function name.
1101 * dependency.c (gfc_check_argument_var_dependency):
1102 Move the check for pointerness inside the if block
1103 so that it doesn't affect the return value.
1106 * trans-stmt.c (gfc_trans_call):
1107 Add the dependency code after the loop bounds calculation one.

1124 * resolve.c (gfc_iso_c_func_interface):
1125 Use gfc_is_data_pointer to test for pointer attribute.
1126 * dependency.c (gfc_is_data_pointer):
1127 Support pointer-returning functions.
1129 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
1131 * symbol.c (save_symbol): Don't SAVE function results.
1133 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
1136 * resolve.c (resolve_call): When searching for proper host
1137 association, use symtree rather than symbol. For everything
1138 except generic subroutines, substitute the symtree in the call
1139 rather than the symbol.
