2087 2009-01-10 Paul Thomas <pault@gcc.gnu.org>
2090 * resolve.c (check_host_association): Use the symtree name to
2091 search for a potential contained procedure, since this is the
2092 name by which it would be referenced.

2097 * interface.c (gfc_procedure_use): Don't warn about functions
2099 * symbol.c (generate_isocbinding_symbol): Mark c_loc and
2102 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2105 * module.c (write_common_0): Use the name of the symtree rather
2106 than the common block, to determine if the common has been
2109 2009-01-05 Daniel Franke <franke.daniel@gmail.com>
2112 * check.c (gfc_check_random_seed): Added size check for GET
2113 dummy argument, reworded error messages to follow common pattern.
2115 2009-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2118 * trans-types.c (gfc_get_derived_type): Check for the
2119 presence of derived->ns->proc_name before
2120 accessing derived->ns->proc_name->attr.flavor .
2121 * resolve.c (resolve_symbol): Likewise.
2123 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2126 * gfortran.h : Add bit to gfc_expr 'user_operator'
2127 * interface.c (gfc_extend_expr): Set the above if the operator
2128 is substituted by a function.
2129 * resolve.c (check_host_association): Return if above is set.
2131 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2134 * ChangeLog-2008: Fix function name.
2137 * dependency.c (gfc_check_argument_var_dependency):
2138 Move the check for pointerness inside the if block
2139 so that it doesn't affect the return value.
2142 * trans-stmt.c (gfc_trans_call):
2143 Add the dependency code after the loop bounds calculation one.
2145 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
2147 * intrinsic.c (do_simplify): Removed already implemented TODO.

2156 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2159 * gfortran.h (gfc_is_data_pointer): Added prototype
2160 * resolve.c (gfc_iso_c_func_interface):
2161 Use gfc_is_data_pointer to test for pointer attribute.
2162 * dependency.c (gfc_is_data_pointer):
2163 Support pointer-returning functions.
2165 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
2167 * symbol.c (save_symbol): Don't SAVE function results.
2169 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
2172 * resolve.c (resolve_call): When searching for proper host
2173 association, use symtree rather than symbol. For everything
2174 except generic subroutines, substitute the symtree in the call
2175 rather than the symbol.
