3146 * trans-array.c (symbols_could_alias): ... here.
3147 Pass information about pointer and target status as
3148 arguments. Allocatable arrays don't alias anything
3149 unless they have the POINTER attribute.
3150 (gfc_could_be_alias): Keep track of pointer and target
3151 status when following references. Also check if typespecs
3152 of components match those of other components or symbols.

3172 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
3173 * resolve.c (resolve_deallocate_expr): _data component will be added
3174 at translation stage.

3189 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3190 'vtab' is initialized).
3192 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3195 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
3196 assignment, set the _vptr component to the declared type.

3202 check for duplicate occurence of allocation/deallocation objects.
3204 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3207 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
3208 of polymorphic allocatables according to their declared type.
3210 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3213 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3214 routine to make sure it receives module name mangling.
