3664 * resolve.c (resolve_actual_arglist): Remove unneeded and buggy piece
3667 2011-01-09 Thomas Koenig <tkoenig@gcc.gnu.org>
3670 * resolve.c (is_scalar_expr_ptr): For a substring reference,

3689 * trans-expr.c (gfc_conv_procedure_call): With a non-copying
3690 procedure argument (eg TRANSPOSE) use a temporary if there is
3691 any chance of aliasing due to host or use association.
3692 (arrayfunc_assign_needs_temporary): Correct logic for function
3693 results and do not use a temporary for implicitly PURE
3694 variables. Use a temporary for Cray pointees.
3695 * symbol.c (gfc_add_save): Explicit SAVE not compatible with
3696 implicit pureness of containing procedure.
3697 * decl.c (match_old_style_init, gfc_match_data): Where decl
3698 would fail in PURE procedure, set implicit_pure to zero.

3700 add prototype for function gfc_implicit_pure.
3701 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
3702 Where decl would fail in PURE procedure, reset implicit_pure.
3703 * io.c (match_vtag, gfc_match_open, gfc_match_close,
3704 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
3705 * match.c (gfc_match_critical, gfc_match_stopcode,

3711 resolve_function, resolve_ordinary_assign) : The same.
3712 (gfc_implicit_pure): New function.
3713 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
3714 to ab_attribute enum and use it in this function.

3719 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
3720 make static and move in front of its only caller, to ...
3721 * trans-array.c (symbols_could_alias): ... here.
3722 Pass information about pointer and target status as
3723 arguments. Allocatable arrays don't alias anything
3724 unless they have the POINTER attribute.
3725 (gfc_could_be_alias): Keep track of pointer and target
3726 status when following references. Also check if typespecs
3727 of components match those of other components or symbols.

3740 2011-01-07 Janus Weil <janus@gcc.gnu.org>
3744 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
3745 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
3747 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
3748 * resolve.c (resolve_deallocate_expr): _data component will be added

3764 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3765 'vtab' is initialized).

3783 of polymorphic allocatables according to their declared type.
3785 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3788 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3789 routine to make sure it receives module name mangling.
