2132 * parse.c (decode_omp_directive): The same.
2133 (parse_contained): If not PURE, set implicit pure attribute.
2134 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
2135 resolve_function, resolve_ordinary_assign) : The same.
2136 (gfc_implicit_pure): New function.
2137 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
2138 to ab_attribute enum and use it in this function.
2140 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
2143 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
2144 make static and move in front of its only caller, to ...
2145 * trans-array.c (symbols_could_alias): ... here.
2146 Pass information about pointer and target status as
2147 arguments. Allocatable arrays don't alias anything
2148 unless they have the POINTER attribute.
2149 (gfc_could_be_alias): Keep track of pointer and target
2150 status when following references. Also check if typespecs
2151 of components match those of other components or symbols.

2156 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.

2158 EXTENDS_TYPE_OF and SAME_TYPE_AS.
2159 * intrinsic.h (gfc_simplify_extends_type_of,
2160 gfc_simplify_same_type_as): New prototypes.
2161 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
2162 gfc_simplify_same_type_as): New functions.
2164 2011-01-07 Janus Weil <janus@gcc.gnu.org>
2168 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
2169 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
2171 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2172 * resolve.c (resolve_deallocate_expr): _data component will be added
2173 at translation stage.
2174 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
2175 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
2177 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
2181 * parse.c (parse_interface): Remove check for procedure types.
2182 * interface.c (check_interface0): Verify that procedures are
2183 either all SUBROUTINEs or all FUNCTIONs.
2185 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2188 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2189 'vtab' is initialized).
2191 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2194 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
2195 assignment, set the _vptr component to the declared type.
2197 2011-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2200 * resolve.c (resolve_allocate_deallocate): Follow references to
2201 check for duplicate occurence of allocation/deallocation objects.
2203 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2206 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2207 of polymorphic allocatables according to their declared type.
2209 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2212 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2213 routine to make sure it receives module name mangling.
2215 2011-01-03 Jakub Jelinek <jakub@redhat.com>
2217 * gfortranspec.c (lang_specific_driver): Update copyright notice
2220 2011-01-03 Janus Weil <janus@gcc.gnu.org>
2222 * intrinsic.texi (LEADZ): Fix example.
