2130 * trans-array.c (symbols_could_alias): ... here.
2131 Pass information about pointer and target status as
2132 arguments. Allocatable arrays don't alias anything
2133 unless they have the POINTER attribute.
2134 (gfc_could_be_alias): Keep track of pointer and target
2135 status when following references. Also check if typespecs
2136 of components match those of other components or symbols.

2153 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
2154 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
2156 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2157 * resolve.c (resolve_deallocate_expr): _data component will be added
2158 at translation stage.
2159 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.

2166 * parse.c (parse_interface): Remove check for procedure types.
2167 * interface.c (check_interface0): Verify that procedures are
2168 either all SUBROUTINEs or all FUNCTIONs.

2173 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2174 'vtab' is initialized).
2176 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2179 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
2180 assignment, set the _vptr component to the declared type.
2182 2011-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
2185 * resolve.c (resolve_allocate_deallocate): Follow references to
2186 check for duplicate occurence of allocation/deallocation objects.
2188 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2191 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2192 of polymorphic allocatables according to their declared type.
2194 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2197 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2198 routine to make sure it receives module name mangling.
