3637 * parse.c (decode_omp_directive): The same.
3638 (parse_contained): If not PURE, set implicit pure attribute.
3639 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
3640 resolve_function, resolve_ordinary_assign) : The same.
3641 (gfc_implicit_pure): New function.
3642 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
3643 to ab_attribute enum and use it in this function.
3645 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
3648 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
3649 make static and move in front of its only caller, to ...
3650 * trans-array.c (symbols_could_alias): ... here.
3651 Pass information about pointer and target status as
3652 arguments. Allocatable arrays don't alias anything
3653 unless they have the POINTER attribute.
3654 (gfc_could_be_alias): Keep track of pointer and target
3655 status when following references. Also check if typespecs
3656 of components match those of other components or symbols.

3661 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.
3662 * intrinsic.c (add_functions): Use simplify functions for
3663 EXTENDS_TYPE_OF and SAME_TYPE_AS.
3664 * intrinsic.h (gfc_simplify_extends_type_of,
3665 gfc_simplify_same_type_as): New prototypes.
3666 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
3667 gfc_simplify_same_type_as): New functions.
3669 2011-01-07 Janus Weil <janus@gcc.gnu.org>
3673 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
3674 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
3676 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
3677 * resolve.c (resolve_deallocate_expr): _data component will be added
3678 at translation stage.
3679 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
3680 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
3682 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
3686 * parse.c (parse_interface): Remove check for procedure types.
3687 * interface.c (check_interface0): Verify that procedures are
3688 either all SUBROUTINEs or all FUNCTIONs.
3690 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3693 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3694 'vtab' is initialized).
3696 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3699 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
3700 assignment, set the _vptr component to the declared type.
3702 2011-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
3705 * resolve.c (resolve_allocate_deallocate): Follow references to
3706 check for duplicate occurence of allocation/deallocation objects.
3708 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3711 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
3712 of polymorphic allocatables according to their declared type.
3714 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3717 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3718 routine to make sure it receives module name mangling.
3720 2011-01-03 Jakub Jelinek <jakub@redhat.com>
3722 * gfortranspec.c (lang_specific_driver): Update copyright notice
3725 2011-01-03 Janus Weil <janus@gcc.gnu.org>
3727 * intrinsic.texi (LEADZ): Fix example.
