2142 * parse.c (decode_omp_directive): The same.
2143 (parse_contained): If not PURE, set implicit pure attribute.
2144 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
2145 resolve_function, resolve_ordinary_assign) : The same.
2146 (gfc_implicit_pure): New function.
2147 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
2148 to ab_attribute enum and use it in this function.

2157 arguments. Allocatable arrays don't alias anything
2158 unless they have the POINTER attribute.
2159 (gfc_could_be_alias): Keep track of pointer and target
2160 status when following references. Also check if typespecs
2161 of components match those of other components or symbols.

2181 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2182 * resolve.c (resolve_deallocate_expr): _data component will be added
2183 at translation stage.
2184 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.

2191 * parse.c (parse_interface): Remove check for procedure types.
2192 * interface.c (check_interface0): Verify that procedures are
2193 either all SUBROUTINEs or all FUNCTIONs.

2198 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2199 'vtab' is initialized).

2216 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2217 of polymorphic allocatables according to their declared type.
2219 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2222 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2223 routine to make sure it receives module name mangling.
