        (KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.

        * c-common.h: Update prototypes.
        * c-decl.c (struct c_scope): Update commentary.  Remove names,
        names_last, parms, parms_last, tags, and shadowed fields.  Add
        bindings and depth fields.
        (scope_freelist): Move to more appropriate location.
        (c_print_identifier): Update for changes to struct lang_identifier.
        (objc_mark_locals_volatile): Update for new bindings structures.
        (global_bindings_p): Honor c_override_global_bindings_to_false.
        (pushlevel): Rename to push_scope; take no arguments; use the
        scope_freelist; initialize scope->depth and check for overflow.
        (poplevel): Rename to pop_scope; totally rewritten for new bindings
        structures.
        (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
        C_DECL_INVISIBLE, for certain decisions.  Adjust some diagnostics.
        Improve some commentary.  Adjust handling of forward parm decls.
        (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
        Preserve C_DECL_IN_EXTERNAL_SCOPE.
        (warn_if_shadowing): Correct indentation.  Improve diagnostics.

        decls.  Rewrite for new bindings structures.  Improve commentary.
        Eliminate the copy_node call.
        (implicit_decl_warning): Use the "diag" idiom (as seen in
        locate_old_decl) to reduce code duplication; call locate_old_decl
        if appropriate.  Relocate to remove need for forward declaration.
        (implicitly_declare): Adjust for new bindings structures.  Kludge
        around Objective-C not-really-builtin functions.
        (undeclared_variable): Improve diagnostics.  If current_function_decl
        is nonnull but current_function_scope is null, use current_scope.
        Use bind.
        (lookup_tag): Adjust for new bindings structures.  Kludge around
        Objective-C's tag declarations that wind up in the external scope.

        initialize current_file_decl, first_builtin_decl, last_builtin_decl.
        First scope pushed is the external scope, not the global scope.
        (builtin_function): Use bind, not pushdecl.  Adjust other bits
        for new data structures.  Keep track of builtins that should be
        made visible automatically.
        (start_decl): Adjust diagnostics.  Remove unnecessary call to
        expand_decl.
        (grokparms): Return 0 if arg_types is error_mark_node.
        (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
        reversed sense.  Rewrite for new bindings structures.  Do not
        leave any decls in the scope, to prevent pop_scope from doing
        contradictory things with them.
        (finish_struct, finish_enum): Remove redundant diagnostics.
        (build_enumerator): Don't cascade diagnostics for error_mark_node.
        Mark location where -pedantic changes the meaning of the program.

        the external scope.  Split body of the loop to...

        * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
        Warn about YYDEBUG not being defined only if -dy.  Remove no-longer-
        correct loop over multiple translation units; call fatal_error if
        requested to compile more than one file at once.  (This disables
        IMA temporarily - an up-front error being preferable to a crash.)
        * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.

        (parm_declarator_nostarttypename, notype_declarator): Remove
        commented-out productions.
        (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
        an empty TREE_LIST node.  Adjust calls to get_parm_info.
        (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
        to suppress -Wold-style-definition after this error.
        (c_parse_file): Don't clear the binding stack or call
        finish_fname_decls here.  Correct comment.
        * c-typeck.c (same_translation_unit_p): Export.
        (common_type): Use c_override_global_bindings_to_false, not
        pushlevel/poplevel/declare_parm_level.
        * c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
        LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
        and LANG_HOOKS_GETDECLS with do-nothing stubs.
        * objc/objc-lang.c: Likewise.
        * objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
        get_parm_info.
        (OBJC_VOID_AT_END): Delete; replace all uses
        with void_list_node.
        (generate_forward_declaration_to_string_table): Delete.
        * objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.

        * coverage.c (create_coverage): Don't pushdecl anything.
        * langhooks.c (lhd_clear_binding_stack): Call
        lang_hooks.decls.poplevel, not poplevel.
        * tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
        circular list rather than going into an infinite loop.

[Bug bootstrap/14829] [3.5 Regression] Bootstrap comparison failure on hppa64-hp-hpux11.11

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-04-08 20:31 -------
I am wondering if something is miscompiling part of the new code as Zack's code bootstrap just fine on 
almost every other target that I know of.  Could you maybe attach the differences of gcc.c's asm from 
the second and thrid stages?

I've attached the diff for timevar.c which is quite small.  Problem
seems to be with output for .debug_loc.

I'll do gcc.c as well.

I am not familiar with dwarf2 enough to know what these diffs might
mean.  Can someone please investigate a bit further?

Okay thanks. So this might be after all Zack's patch because he did touch the debuging info from C but 
I still spect something is being miscompilied in the sources some where.

I agree.  There must be a code diff in one of the files.
