3642 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
3644 * parse.c (decode_omp_directive): The same.
3645 (parse_contained): If not PURE, set implicit pure attribute.
3646 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
3647 resolve_function, resolve_ordinary_assign) : The same.
3648 (gfc_implicit_pure): New function.
3649 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
3650 to ab_attribute enum and use it in this function.

3655 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
3656 make static and move in front of its only caller, to ...
3657 * trans-array.c (symbols_could_alias): ... here.

3659 arguments. Allocatable arrays don't alias anything
3660 unless they have the POINTER attribute.
3661 (gfc_could_be_alias): Keep track of pointer and target
3662 status when following references. Also check if typespecs
3663 of components match those of other components or symbols.

3672 gfc_simplify_same_type_as): New prototypes.
3673 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
3674 gfc_simplify_same_type_as): New functions.
3676 2011-01-07 Janus Weil <janus@gcc.gnu.org>
3680 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
3681 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
3683 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
3684 * resolve.c (resolve_deallocate_expr): _data component will be added
3685 at translation stage.
3686 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
3687 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
3689 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
3693 * parse.c (parse_interface): Remove check for procedure types.
3694 * interface.c (check_interface0): Verify that procedures are
3695 either all SUBROUTINEs or all FUNCTIONs.
3697 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3700 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3701 'vtab' is initialized).
3703 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3706 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
3707 assignment, set the _vptr component to the declared type.

3712 * resolve.c (resolve_allocate_deallocate): Follow references to
3713 check for duplicate occurence of allocation/deallocation objects.
3715 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3718 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
3719 of polymorphic allocatables according to their declared type.
3721 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3724 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3725 routine to make sure it receives module name mangling.
3727 2011-01-03 Jakub Jelinek <jakub@redhat.com>
