2091 * interface.c (gfc_procedure_use): Don't warn about functions
2093 * symbol.c (generate_isocbinding_symbol): Mark c_loc and
2096 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2099 * module.c (write_common_0): Use the name of the symtree rather
2100 than the common block, to determine if the common has been
2103 2009-01-05 Daniel Franke <franke.daniel@gmail.com>
2106 * check.c (gfc_check_random_seed): Added size check for GET
2107 dummy argument, reworded error messages to follow common pattern.
2109 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2112 * trans-types.c (gfc_get_derived_type): Check for the
2113 presence of derived->ns->proc_name before
2114 accessing derived->ns->proc_name->attr.flavor .
2115 * resolve.c (resolve_symbol): Likewise.
2117 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2120 * gfortran.h : Add bit to gfc_expr 'user_operator'
2121 * interface.c (gfc_extend_expr): Set the above if the operator
2122 is substituted by a function.
2123 * resolve.c (check_host_association): Return if above is set.
2125 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2128 * ChangeLog-2008: Fix function name.
2131 * dependency.c (gfc_check_argument_var_dependency):
2132 Move the check for pointerness inside the if block
2133 so that it doesn't affect the return value.
2136 * trans-stmt.c (gfc_trans_call):
2137 Add the dependency code after the loop bounds calculation one.
2139 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2141 * intrinsic.c (do_simplify): Removed already implemented TODO.
2143 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2146 * simplify.c (gfc_simplify_merge): New.
2147 * intrinsic.h (gfc_simplify_merge): New prototype.
2148 * intrinsic.c (add_functions): Added simplification for MERGE.
2150 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2153 * gfortran.h (gfc_is_data_pointer): Added prototype
2154 * resolve.c (gfc_iso_c_func_interface):
2155 Use gfc_is_data_pointer to test for pointer attribute.
2156 * dependency.c (gfc_is_data_pointer):
2157 Support pointer-returning functions.
2159 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
2161 * symbol.c (save_symbol): Don't SAVE function results.
2163 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
2166 * resolve.c (resolve_call): When searching for proper host
2167 association, use symtree rather than symbol. For everything
2168 except generic subroutines, substitute the symtree in the call
2169 rather than the symbol.
