3650 2011-01-09 Thomas Koenig <tkoenig@gcc.gnu.org>
3653 * resolve.c (is_scalar_expr_ptr): For a substring reference,
3654 use gfc_dep_compare_expr to compare start and end expession.
3655 Add FIXME for using gfc_deb_compare_expr elsewhere.
3657 2011-01-09 Janus Weil <janus@gcc.gnu.org>
3660 * class.c (get_unique_type_string): Make type name start with upper
3663 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
3666 * invoke.texi: Mention -ffree-line-length-none and
3667 -ffixed-line-length-none for preprocessing.
3669 2011-01-08 Paul Thomas <pault@gcc.gnu.org>
3672 * trans-expr.c (gfc_conv_procedure_call): With a non-copying
3673 procedure argument (eg TRANSPOSE) use a temporary if there is
3674 any chance of aliasing due to host or use association.
3675 (arrayfunc_assign_needs_temporary): Correct logic for function
3676 results and do not use a temporary for implicitly PURE
3677 variables. Use a temporary for Cray pointees.
3678 * symbol.c (gfc_add_save): Explicit SAVE not compatible with
3679 implicit pureness of containing procedure.
3680 * decl.c (match_old_style_init, gfc_match_data): Where decl
3681 would fail in PURE procedure, set implicit_pure to zero.
3682 * gfortran.h : Add implicit_pure to structure symbol_attr and
3683 add prototype for function gfc_implicit_pure.
3684 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
3685 Where decl would fail in PURE procedure, reset implicit_pure.
3686 * io.c (match_vtag, gfc_match_open, gfc_match_close,
3687 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
3688 * match.c (gfc_match_critical, gfc_match_stopcode,
3689 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
3691 * parse.c (decode_omp_directive): The same.
3692 (parse_contained): If not PURE, set implicit pure attribute.
3693 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
3694 resolve_function, resolve_ordinary_assign) : The same.
3695 (gfc_implicit_pure): New function.
3696 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
3697 to ab_attribute enum and use it in this function.
3699 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
3702 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
3703 make static and move in front of its only caller, to ...
3704 * trans-array.c (symbols_could_alias): ... here.
3705 Pass information about pointer and target status as
3706 arguments. Allocatable arrays don't alias anything
3707 unless they have the POINTER attribute.
3708 (gfc_could_be_alias): Keep track of pointer and target
3709 status when following references. Also check if typespecs
3710 of components match those of other components or symbols.
3712 2011-01-07 Tobias Burnus <burnus@net-b.de>
3715 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.
3716 * intrinsic.c (add_functions): Use simplify functions for
3717 EXTENDS_TYPE_OF and SAME_TYPE_AS.
3718 * intrinsic.h (gfc_simplify_extends_type_of,
3719 gfc_simplify_same_type_as): New prototypes.
3720 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
3721 gfc_simplify_same_type_as): New functions.
3723 2011-01-07 Janus Weil <janus@gcc.gnu.org>
3727 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
3728 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
3730 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
3731 * resolve.c (resolve_deallocate_expr): _data component will be added
3732 at translation stage.
3733 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
3734 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.

3740 * parse.c (parse_interface): Remove check for procedure types.
3741 * interface.c (check_interface0): Verify that procedures are
3742 either all SUBROUTINEs or all FUNCTIONs.
3744 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3747 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
3748 'vtab' is initialized).
3750 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3753 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
3754 assignment, set the _vptr component to the declared type.

3759 * resolve.c (resolve_allocate_deallocate): Follow references to
3760 check for duplicate occurence of allocation/deallocation objects.
3762 2011-01-05 Janus Weil <janus@gcc.gnu.org>
3765 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
3766 of polymorphic allocatables according to their declared type.
3768 2011-01-04 Janus Weil <janus@gcc.gnu.org>
3771 * class.c (gfc_find_derived_vtab): Set the module field for the copying
3772 routine to make sure it receives module name mangling.
3774 2011-01-03 Jakub Jelinek <jakub@redhat.com>

3779 2011-01-03 Janus Weil <janus@gcc.gnu.org>
