2661 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
2662 Where decl would fail in PURE procedure, reset implicit_pure.
2663 * io.c (match_vtag, gfc_match_open, gfc_match_close,
2664 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
2665 * match.c (gfc_match_critical, gfc_match_stopcode,
2666 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
2668 * parse.c (decode_omp_directive): The same.
2669 (parse_contained): If not PURE, set implicit pure attribute.
2670 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
2671 resolve_function, resolve_ordinary_assign) : The same.
2672 (gfc_implicit_pure): New function.
2673 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
2674 to ab_attribute enum and use it in this function.

2679 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
2680 make static and move in front of its only caller, to ...
2681 * trans-array.c (symbols_could_alias): ... here.
2682 Pass information about pointer and target status as
2683 arguments. Allocatable arrays don't alias anything
2684 unless they have the POINTER attribute.
2685 (gfc_could_be_alias): Keep track of pointer and target
2686 status when following references. Also check if typespecs
2687 of components match those of other components or symbols.

2694 EXTENDS_TYPE_OF and SAME_TYPE_AS.
2695 * intrinsic.h (gfc_simplify_extends_type_of,
2696 gfc_simplify_same_type_as): New prototypes.
2697 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
2698 gfc_simplify_same_type_as): New functions.
2700 2011-01-07 Janus Weil <janus@gcc.gnu.org>
2704 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
2705 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
2707 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
2708 * resolve.c (resolve_deallocate_expr): _data component will be added
2709 at translation stage.
2710 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
2711 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
2713 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
2717 * parse.c (parse_interface): Remove check for procedure types.
2718 * interface.c (check_interface0): Verify that procedures are
2719 either all SUBROUTINEs or all FUNCTIONs.
2721 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2724 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
2725 'vtab' is initialized).

2730 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
2731 assignment, set the _vptr component to the declared type.

2736 * resolve.c (resolve_allocate_deallocate): Follow references to
2737 check for duplicate occurence of allocation/deallocation objects.
2739 2011-01-05 Janus Weil <janus@gcc.gnu.org>
2742 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
2743 of polymorphic allocatables according to their declared type.
2745 2011-01-04 Janus Weil <janus@gcc.gnu.org>
2748 * class.c (gfc_find_derived_vtab): Set the module field for the copying
2749 routine to make sure it receives module name mangling.
