2093 * check.c (gfc_check_random_seed): Added size check for GET
2094 dummy argument, reworded error messages to follow common pattern.
2096 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2099 * trans-types.c (gfc_get_derived_type): Check for the
2100 presence of derived->ns->proc_name before
2101 accessing derived->ns->proc_name->attr.flavor .
2102 * resolve.c (resolve_symbol): Likewise.
2104 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2107 * gfortran.h : Add bit to gfc_expr 'user_operator'
2108 * interface.c (gfc_extend_expr): Set the above if the operator
2109 is substituted by a function.
2110 * resolve.c (check_host_association): Return if above is set.
2112 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2115 * ChangeLog-2008: Fix function name.
2118 * dependency.c (gfc_check_argument_var_dependency):
2119 Move the check for pointerness inside the if block
2120 so that it doesn't affect the return value.
2123 * trans-stmt.c (gfc_trans_call):
2124 Add the dependency code after the loop bounds calculation one.
2126 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2128 * intrinsic.c (do_simplify): Removed already implemented TODO.
2130 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2133 * simplify.c (gfc_simplify_merge): New.
2134 * intrinsic.h (gfc_simplify_merge): New prototype.
2135 * intrinsic.c (add_functions): Added simplification for MERGE.
2137 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2140 * gfortran.h (gfc_is_data_pointer): Added prototype
2141 * resolve.c (gfc_iso_c_func_interface):
2142 Use gfc_is_data_pointer to test for pointer attribute.
2143 * dependency.c (gfc_is_data_pointer):
2144 Support pointer-returning functions.
2146 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
2148 * symbol.c (save_symbol): Don't SAVE function results.
2150 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
2153 * resolve.c (resolve_call): When searching for proper host
2154 association, use symtree rather than symbol. For everything
2155 except generic subroutines, substitute the symtree in the call
2156 rather than the symbol.
