102
        * cp/lex.c (check_newline): If DBX_DEBUGGING_INFO and write_symbols
103
        == DBX_DEBUG, call dbxout_start_new_source_file and

714
        and is_for_scope.
715
        (note_level_for_for):  New function.

        (poplevel):  Special processing if is_for_scope.
717

723
 
724
        * decl2.c (import_export_inline): Class interface hackery does not
725
        apply to synthesized methods.
726
 
727
Sun Aug 20 16:29:00 1995  Mike Stump  
728
 
729
        * search.c (virtual_context): Find the right context more often.
730
        Solves a `recoverable compiler error, fixups for virtual function'
731
        problem.
732
 
733
Sun Aug 20 13:53:24 1995  Mike Stump  
734
 
735
        * except.c (expand_start_all_catch): Ensure that we always transfer
736
        control to the right EH handler, by rethrowing the end label on the
737
        region, instead of hoping we are nested and falling through.
738
        (expand_leftover_cleanups): Likewise.
739
        (end_protect): Since we now rethrow the end label, put a
740
        nop after it, so that outer regions are recognized.
741
        * init.c (build_vec_delete_1): New routine to handle most of vector
742
        deleting, all code moved here from build_vec_delete.
743
        (build_array_eh_cleanup): Use build_vec_delete_1 to do all the real
744
        work.
745
        (expand_vec_init): If the array needs partial destructing, setup an
746
        EH region to handle it.
747
        (build_vec_delete): Move lots of code to build_vec_delete_1, use
748
        build_vec_delete_1 to do the grunt work.
749
 
750
Sat Aug 19 14:25:33 1995  Brendan Kehoe  
751
 
752
        Handle decl attributes properly for function definitions without
753
        previous attribute-loaded declarations.
754
        * decl.c (start_function): New arg ATTRS.  Add a call to
755
        cplus_decl_attributes with it before we create the RTL.
756
        * cp-tree.h (start_function): Update prototype.
757
        * parse.y (fn.def1): Pass ATTRS into start_function instead of
758
        trying to call cplus_decl_attributes too late.  Pass a NULL_TREE
759
        for other use.
760
        * decl2.c (finish_file): Pass NULL_TREE as fourth arg to
761
        start_function.
762
        * method.c (synthesize_method): Likewise.
763
        * except.c (expand_builtin_throw): Likewise for start on __throw.
764
 
765
Sat Aug 19 13:36:08 1995  Mike Stump  
766
 
767
        * class.c (set_rtti_entry): Turn on -fvtable-thunk -frtti support.
768
        This changes -fvtable-thunks vtable layout, so a recompile will be
769
        necessary, if you use -fvtable-thunks.
770
        (get_vtable_entry): Use n, instead of i to be consistent with the
771
        rest of the compiler.
772
        (get_vtable_entry_n): Likewise.
773
        (add_virtual_function): Add a slot for the tdesc, if -fvtable-thunks
774
        are being used.
775
        (finish_struct_1): Likewise.
776
        (skip_rtti_stuff): New routine to collapse similar code from many
777
        different parts of the compiler.  I think I got them all.
778
        (modify_one_vtable): Use it.
779
        (fixup_vtable_deltas1): Likewise.
780
        (override_one_vtable): Likewise.
781
        * decl2.c (mark_vtable_entries): Likewise.

        * tree.c (debug_binfo): Likewise.
783
        * search.c (expand_upcast_fixups): Likewise.
784
        (get_abstract_virtuals_1): Likewise.  Use virtuals, instead of tmp to
785
        consistent with the rest of the compiler.
786
        (get_abstract_virtuals): Likewise.
787
        * cp-tree.h (skip_rtti_stuff): New routine, declare it.
788
        * gc.c (build_headof): Support -fvtable-thunk and -frtti together.
789
        (build_typeid): Likewise.
790
        (build_classof): Remove old style way of doing rtti.  Remove support
791
        for `classof' and `headof'.
792
        * gxx.gperf: Likewise.
793
        * hash.h: Likewise.
794
        * parse.y: Likewise.

796
Fri Aug 18 17:31:58 1995  Jason Merrill  
797
 
798
        * decl.c (start_function): Clear ctor_label and dtor_label.
799
 
800
        * class.c (finish_struct_1): Fix handling of access decls.
801
 
802
Tue Aug 15 19:21:54 1995  Jason Merrill  
803
 
804
        * class.c (finish_struct): Only do minimal processing here, so it
805
        can be used for class template definitions, as well.
806
        (finish_struct_1): New function with the rest of the code.
807
 
808
Tue Aug 15 09:46:16 1995  Mike Stump  
809
 
810
        * class.c (prepare_fresh_vtable): On second though, always build the
811
        offset (see Aug 10 change), unless -fvtable-thunks is given.  It
812
        does this by calling the new routine set_rtti_entry.
813
        (finish_struct): Likewise.
814
        (set_rtti_entry): New routine to update the rtti information at the
815
        start of the vtable.
816
 
817
Mon Aug 14 12:21:22 1995  Brendan Kehoe  
818
 
819
        * error.c (dump_decl, case IDENTIFIER_NODE): Only work on a dtor
820
        if it's declared in the C++ language spec.
821
        (dump_function_decl): Likewise.
822
        (dump_function_name): Likewise.
823
        (ident_fndecl): Make sure we got something back from lookup_name.
824
        * decl.c (start_function): Likewise.
825
 
826
Fri Aug 11 16:52:15 1995  Jason Merrill  
827
 
828
        * call.c (build_method_call): Don't call build_new when calling a
829
        constructor without an instance.
830
 
831
Thu Aug 10 20:00:17 1995  Mike Stump  
832
 
833
        * class.c (prepare_fresh_vtable): Always build the offset to the
834
        complete object, as it doesn't cost much.  This allows dynamic_cast
835
        to void * to work when -frtti isn't given.
836
        (finish_struct): Likewise.
837
 
838
Thu Aug 10 16:31:28 1995  Mike Stump  
839
 
840
        * except.c (build_eh_type): Split out some functionality to new
841
        routine named build_eh_type_type.
842
        (build_eh_type_type): New routine.
843
        (expand_start_catch_block): Use build_eh_type_type, as we never want
844
        the dynamic type of the catch parameter, just the static type.
845
        Fixes core dumps when -frtti is used and one catchs pointers to
846
        classes.
847
 
848
Thu Aug 10 14:55:29 1995  Mike Stump  
849
 
850
        * except.c (expand_builtin_throw): Since we now use normal calling
851
        conventions for __throw, we have to remove the first layer off the
852
        stack, so that the next context we search for handlers is the outer
853
        context instead of the context that had the call to __throw, if we
854
        don't immediately find the desired context.
855
 
856
Tue Aug  8 17:44:23 1995  Jason Merrill  
857
 
858
        * tree.c (cp_expand_decl_cleanup): Returns int, not tree.
859
        * cp-tree.h: Update.
860
 
861
        * parse.y (template_type_parm): Add support for `typename'.
862
 
863
Tue Aug  8 12:06:31 1995  Mike Stump  
864
 
865
        * except.c (expand_internal_throw): New internal routine to throw a
866
        value.
867
        (expand_end_all_catch, expand_leftover_cleanups): All throwers
868
        changed to use `expand_internal_throw' instead of jumping to throw
869
        label.
870
        (expand_end_catch_block, expand_throw): Likewise.
871
        (throw_label): Removed.
872
        (expand_builtin_throw): Changed so that EH parameters are passed by
873
        normal function call conventions.  Completes Aug 4th work.
874
 
875
Fri Aug  4 17:17:08 1995  Mike Stump  
876
 
877
        * cp-tree.h (expand_builtin_throw): Declare it.
878
        * decl2.c (finish_file): Call expand_builtin_throw.
879
        * except.c (make_first_label): Remove.
880
        (init_exception_processing): Don't use a LABEL_REF for throw_label,
881
        instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
882
        other functions that don't really appear in those functions.  This
883
        solves a problem where cc1plus consumed exponential amounts of
884
        memory when -Wall was used.
885
        (expand_end_all_catch, expand_leftover_cleanups,
886
        expand_end_catch_block, expand_throw): Change all uses of
887
        throw_label to match new style.
888
        (do_unwind): Rename parameter to inner_throw_label, as it is now
889
        different from throw_label.  Also, assume that our caller will wrap
890
        the passed label with a LABEL_REF, if needed.
891
        (expand_builtin_throw): Make external, change so that the generated
892
        throw is now a real function.
893
        (expand_exception_blocks): Never generate throw code inside another
894
        function.
895
 
896
Fri Aug  4 12:20:02 1995  Mike Stump  
897
 
898
        * decl.c (grokdeclarator): Move checking of mutable const objects
899
        and mutable static objects down, as we might decide during parsing
900
        to unset staticp or constp (for example, when const is part of the
901
        object being pointed to).
902
 
903
Thu Aug  3 17:13:43 1995  Mike Stump  
904
 
905
        * except.c (output_exception_table_entry): Enhance portability to
906
        weird machines.

        (emit_exception_table): Likewise.
908
 
909
Thu Aug  3 16:41:38 1995  Mike Stump  
910
 
911
        * typeck.c (build_ptrmemfunc): Handle casting of pointer to
912
        non-virtual member functions.
913
 
914
Wed Aug  2 11:58:25 1995  Mike Stump  
915
 
916
        * gc.c (build_typeid): Strip cv qualifiers so that const T&, T&, T
917
        and const T all match.
918
 
919
Wed Aug  2 11:25:33 1995  Mike Stump  
920
 
921
        * except.c (build_eh_type): Strip cv qualifiers so that const T&,
922
        T&, T and const T all match.
923
 
924
Tue Aug  1 14:20:16 1995  Mike Stump  
925
 
926
        * except.c: Fix up comments, cleanup code and eliminate exceptNode,
927
        exceptStack, exceptstack, push_except_stmts, pop_except_stmts,
928
        new_except_stack, push_last_insn, pop_last_insn, insn_save_node and
929
        InsnSave.  Also, numerous speed improvements, and correctness
930
        improvements.  Double faulting in all situations should now be
931
        handled correctly.
932
        (expand_start_all_catch): Instead of having many terminate protected
933
        regions, just have one.
934
        (expand_start_catch_block): No longer have to protect
935
        false_label_rtx, as it isn't used for EH region marking.
936
        (expand_end_catch_block): Expand out EH cleanups here by using
937
        expand_leftover_cleanups.
938
        (expand_end_all_catch): Use sequences instead of playing with insn
939
        links directly.
940
        (expand_exception_blocks): Likewise.  Also protect all catch clauses
941
        with one terminate region.
942
 
943
Mon Jul 31 13:24:30 1995  Jason Merrill  
944

949
 
950

951
        anonymous unions here.

959
 
960
        * method.c (report_type_mismatch): Deal with a bad_arg of 0.

965
 
966
        * decl.c (struct binding_level): Keep list of incomplete decls.
967

968
        (pushdecl): Build up the list.
969
        (hack_incomplete_structures): Walk it and prune completed decls.
970

976
 
977
Thu Jul 27 15:40:48 1995  Jason Merrill

        * tree.c (unsave_expr): New routine to build an UNSAVE_EXPR.
991
        (unsave_expr_now): Backend routine used by tree expander.
992
        (cp_expand_decl_cleanup): Wrap second argument in an UNSAVE_EXPR to
993
        work around a limitation in the backend.  The backend uses the
994
        cleanups multiple times, on disjoint control flows, so we cannot
995
        pass unsaved SAVE_EXPRs to the backend.
996
        * tree.def (UNSAVE_EXPR): New tree code.
997
        * typeck.c (c_expand_return): Move goto/return code up inside
998
        conditional, as we don't always want to do this, we only want to do
999
        this when we don't otherwise finish with this control flow.

Thu Jul 27 10:38:43 1995  Brendan Kehoe  
1002

        * parse.y (reserved_declspecs): Link prefix attributes with declspecs.
1010
        (declmods): Likewise.
1011

        split_specs_attrs or strip_attrs to separate declspecs and attrs.
1013
        (lang_extdef): Delete resetting of prefix_attributes.
1014

        (condition): Use NULL_TREE for prefix_attributes.

1025
 
1026
        * call.c (convert_harshness): Deal with reference conversions before
1027
        others.  Actually do array->pointer decay.  Call comp_target_types
1028
        with pointer types rather than their targets.
1029
 
1030
        * typeck.c (comp_target_types): Avoid assigning D const * to B *.
1031
 
1032

1400
        abstract virtual functions are handled correctly.
1401
 
1402
        * sig.c (build_signature_table_constructor): Store the correct
1403
        delta in signature table entries.  It does not yet work for
1404
        classes with virtual base classes as implementations of signatures.
1405
        (build_signature_method_call): Add the delta to the object_ptr
1406
        before generating the function call.
1407

1409
        pointer itself instead of dereferencing the optr.

1411
        direct and virtual calls.

        default implementations -1 instead of 2.

1416
        expression correspondingly.
1417

1419
        message that said we can't handle multiple inheritance for
1420
        implementations of signatures
1421
        (build_signature_method_call): Use the offset from the sigtable
1422
        entry instead of the vptr field from the signature pointer for
1423
        building a virtual function call.
1424
 
1425
        * class.c (build_vfn_ref): Deleted signature specific code, we don't

        call this function anymore from build_signature_method_call.
1427
 
1428

1429
        field in the object now instead of in the signature pointer/ref.
1430
        (build_vptr_ref): Deleted extern declaration.

1438
        table entry fields to their correct types.
1439
 
1440
        * sig.c (build_signature_table_constructor): Don't call digest_init
1441
        for the fields of a sigtable entry, it's wasted time.
1442
 
1443
        * sig.c (build_signature_table_constructor): Correctly set the
1444
        offset and index fields of a sigtable entry.  Build the constructor
1445
        the way digest_init does, digest_init can't handle initializing an
1446
        anonymous union inside a struct.
1447
        (build_signature_method_call): Use the index field instead of the
1448
        delta field to get the vtable index.
1449

1458
        (init_decl_processing): Initialize these variables.

        (init_decl_processing): Use these variables to build the
1460
        sigtable_entry_type structure.  Rename the code and offset fields
1461
        to tag and delta, respectively; add offset and index fields. Changed
1462
        types of fields from short_integer_type_node to delta_type_node.
1463
        * sig.c (build_signature_table_constructor): Rename code and offset
1464
        to tag and delta, respectively.

        (build_overload_value): Handle pointer to member functions as value
1477
        parameters for templates.
1478
        (build_overload_identifier): Since template parameters are shared
1479
        among all instantiations, we have to substitute in the real types
1480
        in TREE_TYPE (parm).
1481

2620
        * pt.c (tsubst): Don't bother calling cp_build_type_variant, since it

3183
 
3184
        * cvt.c (cp_convert): Don't call convert_to_reference, or

3188
 
3189

3241

        here, rather than from xref_defn_tag.
3243
 
3244
        * parse.y (do_xref): Lose.
3245
        (named_class_head): If we see 'class foo:' we know it's a
3246

3247
 
3248
        * pt.c (push_template_decls): Template parm decls are artificial.

3264

3265

3294
        * sig.c (build_signature_pointer_or_reference_type): Don't set
3295
        IS_AGGR_TYPE for signature pointers/reference so expand_default_init

3297
        * call.c (build_method_call): Treat signature pointers/reference

3307
        (finish_file): Move finish_prevtable_vardecl up to before the global
3308
        initializers are done as tdecls are initialized in the global
3309
        initializer.  Also Pick up any new tdecls or vtables needed by
3310
        synthesized methods.
3311
 
3312
        * class.c (finish_struct): Simplify.  We have to do rtti scanning at
3313
        end, so we might as well do all of it there.
3314

3321
 
3322
        * decl2.c (finish_prevtable_vardecl): New routine, mostly split from
3323
        finish_vtable_vardecl.  It has the first half functionality from

        that routine.
3325
        * decl2.c (finish_vtable_vardecl): Update to not include stuff not
3326

        * decl2.c (finish_file): Call finish_prevtable_vardecl.
3328
        * gc.c (build_generic_desc): Allow it to be called when not at the
3329
        global binding layer, but behave as if we were.
3330
        (build_t_desc): Rearrange a bit so that it really works and is
3331
        easier to follow.
3332
        * class.c (finish_struct): Don't decide on tdecls here, as we have
3333
        to wait until the end of the file in general to decide whether or
3334
        not they come out.
3335
 
3336

3339
        calling the destructor.
3340

        return error_mark_node.
3342
        * call.c (build_method_call): Use the one-argument op delete even if
3343
        it's an error.

3345
        * init.c (build_new): Fix -fthis-is-variable support.
3346
        * call.c (build_method_call): Likewise.
3347
 
3348
        * call.c (convert_harshness): Make conversion from a pointer to bool
3349
        worse than conversion to another pointer.

        vtables whereever they go.
3361
 
3362
        * gc.c (build_t_desc): Remove old way of setting it up, as it wasn't

        right.

Sat Jan 28 09:10:44 1995  Mike Stump  
3366
 
3367
        * decl2.c (finish_vtable_vardecl): Now set the
3368
        interface/implementation of vtables on the first virtual function,
3369
        if one exists, otherwise we use the old method.  This is a major win
3370
        in terms of cutting down the size of objects and executables in
3371
        terms of text space and data space.  Now most of the savings that
3372
        #pragma interface/implementation gives is automatic in a fair number
3373
        of cases.
3374

3376
 
3377
        * decl.c (grokdeclarator): Discard the template parameters in a

3392
 
3393
        * lex.c (check_newline): Set linemode when we see a # directive, and
3394
        unset it when we're done.  Turn all 'return's into 'goto skipline'.
3395
        Fix all uses of '\n', since we won't see it anymore.  Put back the
3396
        character we read before checking for a sysv or target pragma.

3407
        * except.c (expand_throw): Do the newing of the exception object

3458
 
3459
        * class.c (instantiate_type): Use DECL_CHAIN to walk lists instead,
3460
