2665 add prototype for function gfc_implicit_pure.
2666 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
2667 Where decl would fail in PURE procedure, reset implicit_pure.
2668 * io.c (match_vtag, gfc_match_open, gfc_match_close,
2669 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
2670 * match.c (gfc_match_critical, gfc_match_stopcode,
2671 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
2673 * parse.c (decode_omp_directive): The same.
2674 (parse_contained): If not PURE, set implicit pure attribute.
2675 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
2676 resolve_function, resolve_ordinary_assign) : The same.
2677 (gfc_implicit_pure): New function.
2678 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
2679 to ab_attribute enum and use it in this function.
2681 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
2684 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
2685 make static and move in front of its only caller, to ...
2686 * trans-array.c (symbols_could_alias): ... here.
2687 Pass information about pointer and target status as
2688 arguments. Allocatable arrays don't alias anything
2689 unless they have the POINTER attribute.
2690 (gfc_could_be_alias): Keep track of pointer and target
2691 status when following references. Also check if typespecs
2692 of components match those of other components or symbols.
2694 2011-01-07 Tobias Burnus <burnus@net-b.de>
2697 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.
2698 * intrinsic.c (add_functions): Use simplify functions for
2699 EXTENDS_TYPE_OF and SAME_TYPE_AS.
2700 * intrinsic.h (gfc_simplify_extends_type_of,
2701 gfc_simplify_same_type_as): New prototypes.
2702 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
2703 gfc_simplify_same_type_as): New functions.
2705 2011-01-07 Janus Weil <janus@gcc.gnu.org>
2709 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
2710 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
2712 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2713 * resolve.c (resolve_deallocate_expr): _data component will be added
2714 at translation stage.
2715 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
2716 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
2718 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
2722 * parse.c (parse_interface): Remove check for procedure types.
2723 * interface.c (check_interface0): Verify that procedures are
2724 either all SUBROUTINEs or all FUNCTIONs.
2726 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2729 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2730 'vtab' is initialized).
2732 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2735 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
2736 assignment, set the _vptr component to the declared type.

2741 * resolve.c (resolve_allocate_deallocate): Follow references to
2742 check for duplicate occurence of allocation/deallocation objects.
2744 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2747 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2748 of polymorphic allocatables according to their declared type.
2750 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2753 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2754 routine to make sure it receives module name mangling.
2756 2011-01-03 Jakub Jelinek <jakub@redhat.com>
