640 Add FIXME for using gfc_deb_compare_expr elsewhere.
642 2011-01-09 Janus Weil <janus@gcc.gnu.org>
645 * class.c (get_unique_type_string): Make type name start with upper
648 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
651 * invoke.texi: Mention -ffree-line-length-none and
652 -ffixed-line-length-none for preprocessing.
654 2011-01-08 Paul Thomas <pault@gcc.gnu.org>
657 * trans-expr.c (gfc_conv_procedure_call): With a non-copying
658 procedure argument (eg TRANSPOSE) use a temporary if there is
659 any chance of aliasing due to host or use association.
660 (arrayfunc_assign_needs_temporary): Correct logic for function
661 results and do not use a temporary for implicitly PURE
662 variables. Use a temporary for Cray pointees.
663 * symbol.c (gfc_add_save): Explicit SAVE not compatible with
664 implicit pureness of containing procedure.
665 * decl.c (match_old_style_init, gfc_match_data): Where decl
666 would fail in PURE procedure, set implicit_pure to zero.
667 * gfortran.h : Add implicit_pure to structure symbol_attr and
668 add prototype for function gfc_implicit_pure.
669 * expr.c (gfc_check_pointer_assign, gfc_check_vardef_context):
670 Where decl would fail in PURE procedure, reset implicit_pure.
671 * io.c (match_vtag, gfc_match_open, gfc_match_close,
672 gfc_match_print, gfc_match_inquire, gfc_match_wait): The same.
673 * match.c (gfc_match_critical, gfc_match_stopcode,
674 sync_statement, gfc_match_allocate, gfc_match_deallocate): The
676 * parse.c (decode_omp_directive): The same.
677 (parse_contained): If not PURE, set implicit pure attribute.
678 * resolve.c (resolve_formal_arglist, resolve_structure_cons,
679 resolve_function, resolve_ordinary_assign) : The same.
680 (gfc_implicit_pure): New function.
681 * module.c (mio_symbol_attribute): Introduce AB_IMPLICIT_PURE
682 to ab_attribute enum and use it in this function.
684 2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
687 * symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
688 make static and move in front of its only caller, to ...
689 * trans-array.c (symbols_could_alias): ... here.
690 Pass information about pointer and target status as
691 arguments. Allocatable arrays don't alias anything
692 unless they have the POINTER attribute.
693 (gfc_could_be_alias): Keep track of pointer and target
694 status when following references. Also check if typespecs
695 of components match those of other components or symbols.
697 2011-01-07 Tobias Burnus <burnus@net-b.de>
700 * class.c (gfc_build_class_symbol): Mark __vtab as attr.vtab.
701 * intrinsic.c (add_functions): Use simplify functions for
702 EXTENDS_TYPE_OF and SAME_TYPE_AS.
703 * intrinsic.h (gfc_simplify_extends_type_of,
704 gfc_simplify_same_type_as): New prototypes.
705 * simplify.c (is_last_ref_vtab, gfc_simplify_extends_type_of,
706 gfc_simplify_same_type_as): New functions.
708 2011-01-07 Janus Weil <janus@gcc.gnu.org>
712 * gfortran.h (gfc_lval_expr_from_sym): Moved prototype.
713 * class.c (gfc_class_null_initializer): Initialize _vptr to declared
715 * expr.c (gfc_lval_expr_from_sym): Moved here from symbol.c.
716 * resolve.c (resolve_deallocate_expr): _data component will be added
717 at translation stage.
718 * symbol.c (gfc_lval_expr_from_sym): Moved to expr.c.
719 * trans-stmt.c (gfc_trans_deallocate): Reset _vptr to declared type.
721 2011-01-06 Daniel Franke <franke.daniel@gmail.com>
725 * parse.c (parse_interface): Remove check for procedure types.
726 * interface.c (check_interface0): Verify that procedures are
727 either all SUBROUTINEs or all FUNCTIONs.
729 2011-01-05 Janus Weil <janus@gcc.gnu.org>
732 * trans-expr.c (gfc_trans_class_assign): Bugfix for r168524 (make sure
733 'vtab' is initialized).
735 2011-01-05 Janus Weil <janus@gcc.gnu.org>
738 * trans-expr.c (gfc_trans_class_assign): For a polymorphic NULL pointer
739 assignment, set the _vptr component to the declared type.
741 2011-01-05 Thomas Koenig <tkoenig@gcc.gnu.org>
744 * resolve.c (resolve_allocate_deallocate): Follow references to
745 check for duplicate occurence of allocation/deallocation objects.
747 2011-01-05 Janus Weil <janus@gcc.gnu.org>
750 * trans-decl.c (gfc_trans_deferred_vars): Initialize the _vpr component
751 of polymorphic allocatables according to their declared type.
753 2011-01-04 Janus Weil <janus@gcc.gnu.org>
756 * class.c (gfc_find_derived_vtab): Set the module field for the copying
757 routine to make sure it receives module name mangling.
759 2011-01-03 Jakub Jelinek <jakub@redhat.com>
761 * gfortranspec.c (lang_specific_driver): Update copyright notice
764 2011-01-03 Janus Weil <janus@gcc.gnu.org>
