        and result_type.  When checking for comparison between signed
        and unsigned, use result_type rather than the (possibly shortened)
        type of op0.  Also, don't warn about equality comparison of a
        signed operand to an unsigned constant that fits in the signed
        type.

        * method.c (emit_thunk): Let poplevel know that the last level is

        * decl2.c: Use DECL_NOT_REALLY_EXTERN to indicate that we want to
        emit an inline here.  Associated changes.

        * pt.c: Ditto.
        * typeck.c: Ditto.

        T* -> void*.
        (build_binary_op_nodefault): New variable build_type controls what

        '*instance_ptrptr', rather than having it passed in separately.
        
        * various: Change various consed-up comparison operations to have

        converting to a reference type.
        * method.c (do_build_copy_constructor): Ditto.

        * parse.y (do_xref): Lose.
        (named_class_head): If we see 'class foo:' we know it's a

        * sig.c (build_signature_pointer_or_reference_type): Don't set

        initializer.  Also Pick up any new tdecls or vtables needed by
        synthesized methods.

        * class.c (finish_struct): Simplify.  We have to do rtti scanning at
        end, so we might as well do all of it there.

Tue Jan 31 05:35:02 1995  Jason Merrill  <jason@phydeaux.cygnus.com>

        * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

        easier to follow.
        * class.c (finish_struct): Don't decide on tdecls here, as we have
        to wait until the end of the file in general to decide whether or
        not they come out.

        right.

Sat Jan 28 09:10:44 1995  Mike Stump  <mrs@cygnus.com>

        * decl2.c (finish_vtable_vardecl): Now set the
        interface/implementation of vtables on the first virtual function,
        if one exists, otherwise we use the old method.  This is a major win
        in terms of cutting down the size of objects and executables in
        terms of text space and data space.  Now most of the savings that
        #pragma interface/implementation gives is automatic in a fair number
        of cases.

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

        make sure we still match them.

        * parse.y: Add END_OF_LINE token.

        * lex.c (check_newline): Set linemode when we see a # directive, and
        unset it when we're done.  Turn all 'return's into 'goto skipline'.
        Fix all uses of '\n', since we won't see it anymore.  Put back the
        character we read before checking for a sysv or target pragma.
        (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
        (handle_sysv_pragma): Don't look at the input stream; quit when we
        see an END_OF_LINE token.

        of a line.

        will suffice to convert from integer_zero_node.

Wed Jan 25 15:02:09 1995  David S. Miller  (davem@nadzieja.rutgers.edu)

        * class.c (instantiate_type): Change error message text.

        * cp-tree.h (THUNK_DELTA):  It is normally negative, so
        use signed .i variant of frame_size rather than unsigned .u.
        * cp-tree.h (VTABLE_NAME_FORMAT):  If flag_vtable_thunks,
        use "VT" rather than "vt" due to binary incompatibility.
        * class.c (get_vtable_name):  Use strlen of VTABLE_NAME_FORMAT,
        rather than sizeof, since it is now an expression.

        Reimplement vtable building, and most vtable pointer setting.
        Allows for earier maintenance, easier understandability, and most
        importantly, correct semantics.

        * class.c (finish_base_struct): Setup BINFO_VTABLE and

        unmark_finished_struct.
        * class.c (overrides): New routine.

        expand_indirect_vtbls_init.  Change init_vtbl_ptrs call to

        expand_indirect_vtbls_init.  General cleanup.  Use

        (finish_function): Don't look at overloads_to_forget.

        Copy enum_overflow logic from c-decl.c.
        * decl.c (start_enum): Initialize enum_overflow.
        (build_enumerator): Use enum_overflow.  Also use current_scope().

        Horrible kludge to prevent templates from being instantiated by

        * parse.y (template_instantiate_once): Unset TYPE_BEING_DEFINED
        before we get to left_curly.
        * pt.c (instantiate_class_template): Set TYPE_BEING_DEFINED.

        * decl.c (pushdecl): If the old duplicate decl was a TYPE_DECL,
        update the IDENTIFIER_TYPE_VALUE of its name.

        * decl2.c (finish_file): When processing the initializer for a

Thu Apr 14 16:12:31 1994  Jason Merrill  (jason@deneb.cygnus.com)

        Improve local class support; allow classes in different blocks to
        have the same name.

        class methods.
        * method.c (do_inline_function_hair): Ditto.

        constructors to have nonstatic const and reference members.

Thu Apr 14 07:15:11 1994  Brendan Kehoe  (brendan@lisa.cygnus.com)

        * decl.c (push_overloaded_decl): Avoid giving errors about
        built-ins, since duplicate_decls will have given warnings/errors
        for them.

Thu Apr 14 03:45:12 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * cvt.c (convert_to_reference): Warn about casting pointer type to
        reference type when this is probably not what they wanted.

Wed Apr 13 13:12:35 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * decl.c (finish_decl):  Don't mindlessly set TREE_USED for
        static consts any more (toplev.c has now been modified to
        not emit warnings if they are unused).

Wed Apr 13 00:22:35 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl.c (grok_op_properties): If op new/delete get here with

        (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
        clobbered.

        * decl.c (start_function): Only warn about `void main()' if pedantic
        || warn_return_type.

Tue Apr 12 02:14:17 1994  Jason Merrill  (jason@deneb.cygnus.com)

        Clean up overloading of the template name.
        * class.c (pushclass): overload the template name whenever pushing
        into the scope of a template class, not just if it is
        uninstantiated.

        * search.c (push_class_decls): Don't overload_template_name.

        * method.c (build_opfncall): Only pass one argument to global op
        delete.

        * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
        decide how many arguments to use for vec delete.

        * decl.c (grok_op_properties): Be consistent in modifying
        current_class_type.
        (grokdeclarator): Only complain about function decls with no return
        type if we're being pedantic.

Mon Apr 11 00:10:53 1994  Jason Merrill  (jason@deneb.cygnus.com)

        Add support for operator new [] and operator delete [].

        * ptree.c (print_lang_type): Indicate vec new/delete.
        * parse.y: Support vec new/delete.
        * method.c (build_decl_overload): Deal with vec new/delete.
        (build_opfncall): Ditto.
        * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
        vec new/delete.  vec new uses "__vn", and vec delete uses "__vd".
        * init.c (init_init_processing): Set up BIVN and BIVD.
        (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,

        (build_x_delete): Support vec delete.
        (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
        and pass it to build_x_delete.
        * decl2.c (delete_sanity): Don't change behavior by whether or not
        the type has a destructor.  Pass use_global_delete to
        build_vec_delete.
        (coerce_delete_type): Make sure that the type returned has a first
        argument of ptr_type_node.

        new/delete.
        (grokdeclarator): Also force vec new/delete to be static.
        (grok_op_properties): Note presence of vec new/delete, and play with
        their args.  If vec delete takes the optional size_t argument, set
        TYPE_VEC_DELETE_TAKES_SIZE.
        * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
        checking for one delete or the other.
        (lang_type): gets_new and gets_delete are now two bits long.  The
        low bit is for the non-array version.  Lose gets_placed_new.
        (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
        delete defined by this class wants to know how much space it is
        deleting.
        (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
        add a header containing the number of elements in the vector; i.e.

        the size.
        * class.c (finish_struct_methods): Also check for overloading vec
        delete.
        * call.c (build_method_call): Also delete second argument for vec

        (grokdeclarator): Fix segfault on null declarator.
        (decls_match): Also accept redeclaration with no arguments if both
        declarations were in C context.  Bash TREE_TYPE (newdecl) here.
        (duplicate_decls): Instead of here.

        * parse.y (nested_name_specifier_1): Lose rules for dealing with
        syntax errors nicely, since they break parsing of 'const i;'.

        * decl.c (lookup_name): if (got_scope == current_class_type)
        val = IDENTIFIER_CLASS_VALUE (name).

        * search.c (lookup_nested_tag): Look in enclosing classes, too.

        * spew.c (yylex): Only look one character ahead when checking for a
        SCOPE.

        * lex.c (check_newline): Read first nonwhite char before

        * decl.c (grokdeclarator): Don't claim that typedefs are variables
        in warning.

        * parse.y: Divide up uses of unqualified_id into
        notype_unqualified_id and unqualified_id, so that TYPENAME can be
        used as an identifier after an object.

        * class.c (push_nested_class): Don't push into non-class scope.

        * decl.c (grokdeclarator): If an identifier could be a type
        conversion operator, but has no associated type, it's not a type
        conversion operator.

        * pt.c (unify): Check for equality of constants better.

        * decl.c (grokdeclarator): Don't complain about access decls.

Sun Apr 10 02:39:55 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl.c (grokdeclarator): pedwarn about data definitions without
        types here.

        * parse.y (datadef): Don't pedwarn about decls without types here,
        since that is valid for functions.
        (fn.def2, component_decl): Support constructors with declmods again.
        (nomods_initdecls): For decls without any mods, so that we don't try
        to get declspecs from some arbitrary $0.

        * search.c (lookup_field): Use cp_error.

        * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
        here; it breaks destructors for non-aggr types.

        * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
        a type being defined, like the comment says.
        If got_scope is not an aggregate, just return NULL_TREE.

        * pt.c (create_nested_upt): Kung's code for creating types nested
        within uninstantiated templates now lives here (it used to live in
        hack_more_ids).  It needs to be expanded.

        * parse.y: Stop calling see_typename so much.

        * decl.c (lookup_name): Deal with TTPs and UPTs.

        * lex.c (real_yylex): Don't set looking_for_typename just because we
        saw a 'new'.
        (dont_see_typename): #if 0 out.

        * spew.c (yylex): Increment looking_for_typename if the next
        character is SCOPE, rather than setting it to 1; this way, the value
        from seeing an aggr specifier will not be lost.  This kinda relies
        on looking_for_typename never being < 0, which is now true.

        * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
        too.
        (named_class_head_sans_basetype): Accept template types, too.  Oops.

Fri Apr  8 16:39:35 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.

        * parse.y: Lose START_DECLARATOR.

        * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
        for a class.

        * parse.y: Simplify fn.def2 and component_decl.  Support 'enum
        A::foo' syntax.  Catch invalid scopes better.

        * parse.y, lex.c: lose TYPENAME_COLON.

        * decl2.c (groktypefield): #if 0 out.

        * decl.c (lookup_name): If the type denoted by got_scope is
        currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.

        * class.c (push_nested_class): Don't try to push into
        error_mark_node.

Fri Apr  8 07:26:36 1994  Brendan Kehoe  (brendan@lisa.cygnus.com)

        * Makefile.in (stamp-parse): Update count of conflicts to 33.

Thu Apr  7 17:47:53 1994  Jason Merrill  (jason@deneb.cygnus.com)

        A saner implementation of nested types that treats template types
        no differently from non-template types.  There are still some
        shortcomings of our system; most notably, it is difficult to look
        for a nested type that is hidden by another name, because of the way
        we keep track of hidden types.  But this shouldn't be a problem for
        just about anyone.  Perhaps lookup_field should be fixed up a bit.

        * spew.c: Moved handling of nested types/scoping from the lexer
        into the parser.  Removed variable template_type_seen_before_scope.
        Removed functions frob_identifier, hack_more_ids, and various cruft
        that was #if 0'd out in the past, reducing the size of the file from
        1146 lines to 450 lines.  We can't quite do away with spew.c yet,
        though; we still need it for do_aggr () and checking for SCOPE after
        the current identifier.  And setting lastiddecl.

        * parse.y: Moved handling of nested types/scoping from the lexer
        into the parser, using a new global variable `got_scope'.  Reduced
        the number of states by 53.  Implemented all uses of explicit global
        scope.  Removed terminals SCOPED_TYPENAME and SCOPED_NAME.  Removed
        nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
        scoped_typename.  Added nonterminals nested_type,
        qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
        nested_name_specifier, global_scope, overqualified_id, type_name.
        Changed many others.  Added 9 new reduce/reduce conflicts, which are
        nested type parallels of 9 that were already in the grammar for
        non-nested types.  Eight of the now 33 conflicts should be removed
        in the process of resolving the late binding between variable and
        function decls.

        * gxxint.texi (Parser): Update.

        * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.

        * lex.h: Add decl for got_scope.

        * lex.c (see_typename): Claim to be the lexer when calling
        lookup_name.

        * decl.c (lookup_name): When called from the lexer, look at
        got_scope and looking_at_typename; otherwise don't.

        31th Cygnus<->FSF merge.

Thu Apr  7 17:47:53 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl2.c (mark_vtable_entries): Call this to mark all the

        (finish_decl_parsing): Handle SCOPE_REFs.

        * typeck.c (compparms): Also allow t1 to be ... if strict == 0.

        * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
        ch-tree.h:  Every place these functions were called, the result was
        immediately passed to expand_expr_stmt.  Reduce redundancy by
        calling expand_expr_init *inside* these functions.  These
        makes for a simpler interface, and we don't have to build
        compound expressions.  Hence, rename these function to:
        expand_virtual_init and expand_vbase_vtables_init respectively.
        * init.c, decl.c:  Change callers of these functions.
        * init.c, cp-tree.h (expand_virtual_init):  Make static.

        * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE

        * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.

        * decl.c (duplicate_decls): If this is a new declaration of an
        extern "C" function, keep the type (for the argtypes).
        (redeclaration_error_message): Don't check DECL_LANGUAGE here.
        (decls_match): Call compparms with a value of strict dependent on
        the value of strict_prototypes for DECL_LANGUAGE (oldecl).

        * typeck.c (compparms): ... is only equivalent to non-promoting
        parms if we're not being strict.

        * parse.y (empty_parms): Don't check flag_ansi || pedantic here.

        * decl.c (init_decl_processing): if (flag_ansi || pedantic)
        strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;

        * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure
        virtuals.

        * class.c (build_vfn_ref):  If using thunks, don't need
        to add delta field from vtable (there is none!).
        * decl.c: Add memptr_type as well as vtable_entry_type.
        If using thunks, the latter is just ptr_type_node.
        * gc.c, typeck.c:  Use memptr_typeChange, not vtable_entry_type.
        * decl2.c (finish_vtable_vardecl):  Handle thunks.
        * expr.c (cplus_expand_expr):  Support THUNK_DECL.

        and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
        * decl2.c (finish_file):  Writing out inlines later, so we can
        also handle the ones needed for vtbales.
        * decl2.c (write_vtable_entries, finish_vtable_typedecl):  Removed.

        * cp-tree.h, class.c, decl2.c, search.c:  Remove -fvtable-hack
        and flag_vtable_hack.   Use -fvtable-thunks and flag_vtable_thunks
        instead.  (The rationale is that these optimizations both break binary
        compatibility, but should become the default in a future release.)

Wed Apr  6 10:53:56 1994  Mike Stump  <mrs@cygnus.com>

        * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT

Tue Apr  5 17:23:45 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * typeck.c (c_expand_return):  Before checking that we're not
        returning the address of a local, make sure it's a VAR_DECL.
        (And don't worry about it being a TREE_LIST.)

Tue Apr  5 13:26:42 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (YYDEBUG): Always define.
        * lex.c (YYDEBUG): Ditto.

Mon Apr  4 11:28:17 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * class.c (finish_struct): backup out the change below, put the
        new change for the same purpose. The change below breaks code.

        * class.c (finish_struct): if pure virtual, copy node and make
        RTL point to abort, then put in virtual table.

        * call.c (build_method_call): When looking at global functions,

        of it that has been cast to a base class.  Also do this before
        comparing candidates.

        have been overridden in a derived class.

        * decl.c (grokfndecl): Put back clearing of DECL_CHAIN for

        * parse.y (after_type_declarator1): Expand type_quals.
        (notype_declarator1): Ditto.
        (absdcl1): Ditto.

Sat Mar 19 01:05:17 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl.c (grokdeclarator): Treat class-local typedefs like static
        members; i.e. 'typedef int f();' means that f is a function type,
        not a method type.

        * parse.y (decl): Change direct_* back to *.
        (type_id): Change direct_abstract_declarator to absdcl.
        (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.

Fri Mar 18 12:47:59 1994  Jason Merrill  (jason@deneb.cygnus.com)

        These two patches fix crashes on instantiating a template inside a
        function with C linkage or containing labels.

        * class.c (current_lang_stacksize): No longer static.

        * decl.c (struct saved_scope): Add lang_base, lang_stack,
        lang_name, lang_stacksize, and named_labels.
        (push_to_top_level): Save them.
        (pop_from_top_level): Restore them.

        * gxxint.texi (Parser): Update.

        These two patches finish moving the task of expr/declarator
        ambiguity resolution from the lexer to the parser, and add one more
        r/r conflict.  START_DECLARATOR can now be nuked.

        * parse.y (decl): Add "direct_" in typespec X rules.
        (direct_declarator): New nonterminal for
        direct_after_type_declarator and direct_notype_declarator.
        (direct_initdecls): Like initdecls, but uses direct_initdcl0.
        (direct_initdcl0): Like initdcl0, but uses direct_declarator.
        (named_parm): Add typespec direct_declarator rule.

        * spew.c (yylex): #if 0 out START_DECLARATOR insertion.

        These two patches disable some excessive cleverness on the part of
        g++; a non-class declaration always hides a class declaration in the
        same scope, and g++ was trying to unhide it depending on the
        enclosing expression.

        * spew.c (arbitrate_lookup): #if 0 out.

        * decl.c (lookup_name): Never call arbitrate_lookup.

        * parse.y (complex_notype_declarator1): Add '*'
        complex_notype_declarator1 and '&' complex_notype_declarator1 rules.

        * parse.y (complex_direct_notype_declarator): Restore id_scope
        see_typename TYPENAME rule, remove all other rules beginning with
        those tokens.
        (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.

Thu Mar 17 17:30:01 1994  Jason Merrill  (jason@deneb.cygnus.com)

        These changes fix the compiler's handling of the functional cast/
        object declaration ambiguities in section 6.8 of the ARM.  They also
        add 11 reduce/reduce conflicts.  Sigh.

        * parse.y: Add precedence decls for OPERATOR and '~'.
        (notype_unqualified_id): New nonterminal, encompasses all of the
        ANSI unqualified-id nonterminal except TYPENAMEs.
        (expr_or_declarator): New nonterminal to delay parsing of code like
        `int (*a)'.
        (primary): Use notype_unqualified_id.
        (decl): Add typespec initdecls ';' and typespec declarator ';'
        rules.
        (initdcl0): Deal with the above.
        (complex_notype_declarator1): A notype_declarator that is not also
        an expr_or_declarator.
        (complex_direct_notype_declarator): A direct_notype_declarator that
        doesn't conflict with expr_or_declarator.  Use
        notype_unqualified_id.  Remove id_scope see_typename TYPENAME rule.
        (functional_cast): New nonterminal, for the three functional cast
        rules.  So that they can be moved after
        complex_direct_notype_declarator.
        (see_typename): Don't accept type_quals any more.

        * decl2.c (reparse_decl_as_expr): New function to deal with parse
        nodes for code like `int (*a)++;'.      
        (reparse_decl_as_expr1): Recursive subroutine of the above.
        (finish_decl_parsing): New function to deal with parse nodes for
        code like `int (*a);'.  See the difference?

Thu Mar 17 12:16:10 1994  Mike Stump  <mrs@cygnus.com>

        These changes break binary compatibility in code with classes
        that use virtual bases.

        * search.c (dfs_get_vbase_types): Simplify and correct to make
        sure virtual bases are initialized in dfs ordering.
        * search.c (get_vbase_types): Simplify and make readable.

Thu Mar 17 12:01:10 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y: s/ typename / type_id /g

Wed Mar 16 17:42:52 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * parse.y (typespec): add SCOPE TYPENAME for global scoped 
        type. e.g. ::B x.

        * decl.c (complete_array_type): fix a bug that in -pendantic
        mode even there's no initializer, it will continue to build
        default index.

Wed Mar 16 17:43:07 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
        all of the scoped PTYPENAME rules.

Wed Mar 16 16:39:02 1994  Mike Stump  <mrs@cygnus.com>

        * init.c (build_offset_ref): The value of A::typedef_name is
        always the TYPE_DECL, and never an error.

Tue Mar 15 20:02:35 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * search.c (get_base_distance_recursive): Two binfos can only
        represent the same object if they are both via_virtual.

        * class.c (finish_base_struct): Check vbases for ambiguity, too.

        * search.c (get_vbase_types): Accept binfo argument, too.

Tue Mar 15 19:22:05 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * decl.c (complete_array_type): complete TYPE_DOMAIN of the 
        initializer also, because back-end requires it.

Tue Mar 15 15:33:31 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * error.c (dump_expr): Support member functions (which show up as
        OFFSET_REFs).

Mon Mar 14 16:24:36 1994  Mike Stump  <mrs@cygnus.com>

        * init.c (build_new): Set the return type of multidimensional
        news correctly.

Fri Mar 11 15:35:39 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * call.c (build_method_call): if basetype not equal to type
        of the instance, use the type of the instance in building
        destructor.

Thu Mar 10 17:07:10 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * parse.y (direct_notype_declarator): add push_nested_type for
        'template_type SCOPED_NAME' rule.

Tue Mar  8 00:19:58 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (parm): Add typed_declspec1 {absdcl, epsilon} rules.

Sat Mar  5 04:47:48 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (regcast_or_absdcl): New nonterminal to implement late
        reduction of constructs like `int ((int)(int)(int))'.
        (cast_expr): Use it.
        (sub_cast_expr): Everything that can come after a cast.
        (typed_declspecs1): typed_declspecs that are not typed_typespecs.
        (direct_after_type_declarator): Lose PAREN_STAR_PAREN rule.
        (direct_abstract_declarator): Replace '(' parmlist ')' rule with
        '(' complex_parmlist ')' and regcast_or_absdcl.

        (complex_parmlist): Parmlists that are not also typenames.
        (parms_comma): Enabler.
        (named_parm): A parm that is not also a typename.  Use declarator
        rather than dont_see_typename abs_or_notype_decl.  Expand
        typed_declspecs inline.
        (abs_or_notype_decl): Lose.
        (dont_see_typename): Comment out.
        (bad_parm): Break out abs_or_notype_decl into two rules.

Fri Mar  4 18:22:39 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl2.c (reparse_decl_as_casts): New function to change parse
        nodes for `(int)(int)(int)' from "function taking int and returning
        function taking int and returning function taking int" to "... cast
        to int, cast to int, cast to int".

        * decl2.c (reparse_decl_as_expr): Recursive function to change
        parse nodes for `A()()' from "function returning function returning
        A" to "A().operator()".

        * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
        `typespec fcast_or_absdcl' rule.
        (fcast_or_absdcl): New nonterminal to implement late reduction of
        constructs like `A()()()()'.

        `typespec direct_abstract_declarator' rule.
        (direct_abstract_declarator): Replace `LEFT_RIGHT type_quals' rule
        with `fcast_or_absdcl type_quals' rule.

Fri Mar  4 16:18:03 1994  Mike Stump  <mrs@cygnus.com>

        * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
        matches Section 5.5.

Fri Mar  4 14:01:59 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * error.c (dump_type_prefix): Don't print basetype twice for
        pmfs.

        * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
        so that it is like setHandler(&A::handlerFn).  Cures an `invalid
        lvalue in unary `&''.

Fri Mar  4 11:15:59 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * gxxint.texi (Copying Objects): New section discussing default
        op= problems with virtual inheritance.

        * decl2.c (grokoptypename): Just does grokdeclarator and
        build_typename_overload, since the parser can't call grokdeclarator
        directly.

        * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
        and TREE_TYPE on generated identifiers.

        * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.

        if we can't figure out what to do.
        (dump_type*): Ditto.

        * typeck2.c (build_m_component_ref): 'component' is an expr, not
        a decl.  Also move the IS_AGGR_TYPE check after the stripping of
        REFERENCE_TYPE.

Fri Mar  4 04:46:05 1994  Mike Stump  <mrs@cygnus.com>

        * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
        so that it is like b->setHandler(&A::handlerFn).  Cures an `invalid

Thu Mar  3 12:38:15 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y: Add precedence specification for START_DECLARATOR.
        (type_quals): Move before primary.
        (typename): Move before typed_declspecs, add 'typespec absdcl1' rule.

        * decl2.c (grokoptypename): Lose.

        * decl.c (grokdeclarator): Parse TYPE_EXPRs in the initial scan,
        rather than waiting until later.

Wed Mar  2 14:12:23 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
        than expanding it inline.
        (typename): Expand empty option of (former) absdcl inline.
        (abs_or_notype_decl): Ditto.
        (absdcl): Lose empty rule.
        (conversion_declarator): New nonterminal for 'typename' of 'operator
        typename'.
        (operator_name): Use it instead of absdcl.

        * parse.y: Add precedence declarations for SCOPED_TYPENAME,
        TYPEOF, and SIGOF.
        (typed_declspecs): Accept typed_typespecs, rather than typespec
        directly.  Add rules with reserved_typespecquals.
        (reserved_declspecs): Don't accept typespecqual_reserved at the
        beginning of the list.  The typed_declspecs rule will deal with this
        omission.
        (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
        directly.

        * parse.y (direct_notype_declarator,
        direct_after_type_declarator, direct_abstract_declarator): Split up
        the declarator1 nonterminals to match the draft standard and avoid
        ambiguities.
        (new_type_id, new_declarator, direct_new_declarator,
        new_member_declarator): New nonterminals to implement the subset of
        'typename' allowed in new expressions.
        (unary_expr): Use new_type_id instead of typename.
        (after_type_declarator1, absdcl1): Fix semantics of member pointers.
        (abs_member_declarator, after_type_member_declarator): Lose.

        * parse.y (absdcl1): Don't require parens around
        abs_member_declarator.
        (abs_member_declarator): Lose see_typename from rules.
        (after_type_member_declarator): Ditto.

        * tree.c (get_identifier_list): New function, containing code
        previously duplicated in get_decl_list and list_hash_lookup_or_cons.
        (get_decl_list): Use it.
        (list_hash_lookup_or_cons): Ditto.

        * parse.y (typed_declspecs, declmods): It's not necessary to hash
        the declspecs on class_obstack, so don't.  This way typed_typespecs
        can reduce to typed_declspecs.

Wed Mar  2 14:29:18 1994  Jason Merrill (jason@cygnus.com)

        * cvt.c (build_up_reference): If we aren't checking visibility,
        also allow base->derived conversions.

        * typeck.c (build_c_cast): Remove bogus hack when converting

        Removed, not used.
        (lang_stype::methods, lang_decl::next_method): New fields.

        * decl.c (duplicate_decls):  Preserve DECL_NEXT_METHOD.

        * cp-tree.h, decl2.c (flag_vtable_hack):  New flag.
        * decl2.c (finish_vtable_vardecl):  If flag_vtable_hack,
        and  !CLASSTYPE_INTERFACE_KNOWN, try to use the presence of
        a non-inline virtual function to control emitting of vtables.
        * class.c (finish_struct):  Build CLASSTYPE_METHODS list.
        * search.c (build_vbase_vtables_init):  Don't assemble_external
        (yet) if flag_vtable_hack.
        * class.c (build_vfn_ref):  Ditto.

Mon Feb 28 14:54:13 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (component_decl): Don't include "typed_declspecs
        declarator ';'" speedup, since it breaks enums.

Fri Feb 25 15:43:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * class.c (finish_struct):  Minor optimization for building

Thu Feb 24 22:26:19 1994  Mike Stump  <mrs@cygnus.com>

        * lex.c (check_newline): #pragma interface can take a string
        argument, just like #pragma implementation.  #pragma implementation
        checks for garbage on the line, line #pragma interface does.  Main
        input files do not auto implement like named files, #pragma
        implementation must be used explicitly.

Thu Feb 24 17:09:01 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y (components): Handle list of one again.
        (notype_components): Ditto.

        * Makefile.in (stamp-parse): Update expected conflict count.

        * parse.y (various): Replace "declmods declarator" with "declmods
        notype_declarator".  The comment saying that "declmods declarator ';'"
        corresponds to "int i;" was wrong; it corresponds to "const i;".
        (component_decl): Add "typed_declspecs declarator ';'" rule; this
        *does* correspond to "int i;".  Change "declmods components" to
        "declmods notype_components".
        (components): Don't deal with a list of one anymore.
        (notype_components): New nonterminal, corresponds to notype_declarator.
        ({after_,no}type_component_decl{,0}): More new nonterminals.
        ({after_,no}type_declarator): Fold in START_DECLARATOR token.
        Eliminates four reduce/reduce conflicts.

        (expr): Depend on nontrivial_exprlist instead of nonnull_exprlist.
        (nontrivial_exprlist): New nonterminal: A list of at least two
        expr_no_commas's.
        (nonnull_exprlist): Depend on nontrival_exprlist.
        Eliminates four reduce/reduce conflicts.

        (named_class_head): Move intermediate code block into separate
        nonterminal so that we can stick %prec EMPTY on it.

        Add more %prec EMPTY's to eliminate remaining shift/reduce
        conflicts.

        (after_type_declarator): Add maybe_raises to fndecl rules.
        (after_type_declarator_no_typename): Remove.

        (TYPE_BINFO (type)) if we care about the path.

        * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
        options are.

Mon Feb 21 19:59:40 1994  Mike Stump  <mrs@cygnus.com>

        * Makefile.in (mostlyclean): lex.c is a source file, don't
        remove.

Sat Feb 19 01:27:14 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * parse.y: Eliminate 20 shift/reduce conflicts.

Fri Feb 18 11:49:42 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * pt.c (type_unification): Add subr argument; if set, it means
        that we are calling ourselves recursively, so a partial match is OK.
        (unify): Support pointers to methods and functions.
        (tsubst): Support method pointers.
        * decl.c (build_ptrmemfunc_type): No longer static, so that
        tsubst can get at it.

        * init.c (is_aggr_typedef): Pretend template type parms are
        aggregates.
        * decl2.c (build_push_scope): If cname refers to a template type
        parm, just grin and nod.

        * pt.c (do_function_instantiation): Ditto.
        * class.c (instantiate_type): Ditto.

        * search.c (get_base_distance): If BINFO is a binfo, use it and
        don't mess with its BINFO_INHERITANCE_CHAIN.

        * cvt.c (convert_to_reference): Fix temporary generation.
        If ambiguous, return error_mark_node.

        * init.c (build_new): Put back some necessary code.

Thu Feb 17 15:39:47 1994  Jason Merrill  (jason@deneb.cygnus.com)

        that provides the most access.
        (get_base_distance): Ditto.

        * parse.y (explicit_instantiation): Syntax is 'template class
        A<int>', not 'template A<int>'.

        * typeck.c (convert_for_initialization): Remove bogus warning.

        * parse.y (datadef): Revert patch of Oct 27.

Thu Feb 17 15:12:29 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * class.c (build_vfn_ref):  Cast delta field to ptrdiff_type_node,
        rather than integer_type_node.  Does wonders for the Alpha.

        on local level, go back to build_cplus_new approach.

        * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
        to error_mark_node to prevent expand_expr from building a cleanup
        for this variable.

        * lex.c (default_assign_ref_body): Return *this from the memcpy
        version, too.

        * decl.c (grok_reference_init): Just return if called with

        with temporary.

        * cvt.c (convert_to_reference): Do the right thing for
        non-aggregate reference conversions, pedwarn when generating a
        non-const reference to a temporary.

        * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
        TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
        again.

Tue Feb 15 19:47:19 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * decl.c (grok_reference_init): Pawn off a lot of the work on
        convert_to_reference.  Generally do the right thing.

        * cvt.c (convert_to_reference): Conform to the initial comment;
        i.e. don't create temps if decl != error_mark_node.  Handle
        cleanups better for temps that do get created.  Don't pretend
        that we can use an 'A' to initialize a 'const double &' just by
        tacking on a NOP_EXPR.  Support LOOKUP_SPECULATIVELY.

        * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

        (which isn't always the inner_binding_level).

        * cvt.c (build_up_reference):  Don't ever call expand_aggr_init.
        It's ugly, and I don't think it's the right thing to do.

        * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c: 
        Remove NEW_CLASS_SCOPING, assuming it is always 1.
        * decl.c (pop_decl_level):  Removed; manually inlined.

            with destructor names when either NO_DOLLAR_IN_LABEL or

            Now `template <class T, T f(T&), const T*> class A {...}' works.

            * pt.c (grok_template_type): substitute template parm types
            with actual types in complex type as well.

        * class.c (build_vbase_path): Use complete_type_p instead of
        resolves_to_fixed_type_p to determine if the virtual bases are in
        their right place for the type of expr.  Cures problem of thinking a
        virtual base class is one place, when it is in fact someplace else.

Fri Feb 11 00:26:46 1994  Mike Stump  <mrs@cygnus.com>

        * init.c (resolve_offset_ref): Make sure we first convert to
        intermediate type, if given, when dealing with members off `this'.
        Solves an incorrrect `type `foo' is not a base type for type
        `multiple'' when it is infact, a base type.

        argument complain to flags to match style of rest of code.

        Stick in flags argument.

        current_class_type and current_function_decl is the most nested.
        (compute_access): Total overhaul to make it clearer and more
        correct.  Don't use the cache for now; in the only situation where
        it was used before, it gained nothing.  This frees up three of the
        DECL_LANG_FLAGs for possible other use!

        * cp-tree.h: #if 0 out DECL_PUBLIC & friends.

        * typeck.c (build_component_ref_1): Don't check DECL_PUBLIC.

        * call.c (build_method_call): Use convert_force to cast `this' --

        * cvt.c (convert_to_reference): Add 8.4.3 checking so that one

        * cp-class.c (is_normal): New routine, use to determine when the

        * cp-class.c (modify_other_vtable_entries): Use DECL_ASSEMBLER_NAME
        to check if two fndecls are `the same'.  Sometimes this routine can
        modify the main vtable, and normal should be 1, in that case, so use
        is_normal() to determine if this is the main vtable for the class.
        Don't recurse down virtual bases, as they are shared, and we take
        care of them elsewhere.
        * cp-class.c (modify_vtable_entries): If we have already updated the
        vtable with the new virtual, don't do it again.

        Use DECL_ASSEMBLER_NAME to check if two fndecls are `the same'.
        Make sure we pass the right address into modify_vtable_entries.
        * cp-tree.h (CLASSTYPE_VFIELD_PARENT): New field to indicate which
        binfo is the one that has the vtable that we based our vtable on.

        (unary_complex_lvalue): Use it.
        (build_modify_expr): Use it, since trying to do an ADDR_EXPR of it
        with build_unary_op won't cut it.  Don't wrap the COND_EXPR with a
        SAVE_EXPR either.

        * cp-decl2.c (explicit_warn_return_type): Deleted variable.
        (lang_decode_option): Set warn_return_type, not explicit_*, for

        * cp-class.c (finish_base_struct): Set cant_synth_* correctly.

        properly with the case where a class contains an object of an
        ambiguous base class which has a protected op=.  Should be fixed
        when the access control code gets overhauled.
        (finish_struct_methods): Set TYPE_HAS_NONPUBLIC_* correctly.

        marker for the end of the list of candidates.

        * cp-cvt.c (convert_to_aggr): Make sure to always set H_LEN.

        when the conversion should be done, regardless.
        * cp-tree.h (build_ptrmemfunc): Ditto.
        * cp-type2.c (digest_init): Ditto.
        * cp-typeck.c (convert_for_assignment): Ditto.

Tue Nov 23 18:06:58 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-error.c (dump_expr): Do the right thing for variables of
        reference type.

        * cp-decl.c (grok_op_properties): Set TYPE_HAS_ASSIGN_REF
        and its kin properly.
        (xref_tag): Propagate TYPE_GETS_ASSIGN_REF.

Tue Nov 23 12:26:13 1993  Mike Stump  <mrs@cygnus.com>

        * cp-method.c (build_opfncall): Don't count pointer to member
        functions as aggregates here, as we don't want to look up methods in
        them.  The compiler would core dump if we did, as they don't have
        normal names.
        * cp-typeck.c (build_indirect_ref): Improve wording on error
        message.

Mon Nov 22 14:22:23 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-decl.c (grok_op_properties): Allow operator?: with pedwarn
        (since it's supported in other compiler bits).

        * cp-method.c (report_type_mismatch): Use cp_error; ignore err_name
        argument.

        * cp-error.c (dump_function_decl): Don't print return type for
        constructors and destructors.

        * cp-cvt.c (cp_convert_to_pointer): Import code from
        convert_to_pointer so we can return error_mark_node in the case of an
        error, and to allow more meaningful error messages.
        (build_type_conversion): Don't go through void* when trying
        to convert to a pointer type.

        * cp-decl.c (grokfndecl): Move call to grok_op_properties back
        after grokclassfn so that it's dealing with the right decl.
        (grok_op_properties): Don't assert !methodp for op new and op delete.

        * cp-init.c (build_delete): Don't use TYPE_BUILT_IN (there are now
        no uses of it in the compiler).

        * cp-call.c (build_scoped_method_call): Fix for destructors of simple
        types.
        (build_method_call): Ditto.

Fri Nov 19 12:59:38 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-tree.c (count_functions): Abstraction function.

        * cp-call.c (build_overload_call_real): Deal with new overloading
        properly, remove dead code.

        * gcc.c (default_compilers): Generate and use .ii files in the
        intermediate stage of compiling C++ source.

Fri Nov 19 11:26:09 1993  Jim Wilson  (wilson@sphagnum.cygnus.com)

        * cp-expr.c (cplus_expand_expr): Make call_target a valid memory
        address before using it, so it can be later safely compared.

Fri Nov 12 15:30:27 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-pt.c (tsubst): Deal with new overloading.

        * cp-typeck.c (fntype_p): is the arg function type?
        (comp_target_parms): pedwarn on conversion from (anything) to (...).
        (build_x_function_call): Deal with new overloading.

        * cp-tree.c (decl_list_length): Deal with new overloading.
        (decl_value_member): Like value_member, but for DECL_CHAINs.

        * cp-decl.c (duplicate_decls): Deal with new overloading.
        (start_decl): Ditto.

        * cp-class.c (instantiate_type): Deal with new overloading.

        * cp-call.c (convert_harshness_ansi): Deal with new overloading.
        (convert_harshness_old): Deal with new overloading.
        (build_overload_call_real): Ditto.

Mon Nov  8 13:50:49 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
        if unambiguous, NULL_TREE otherwise.
        (get_first_fn): Returns the first appropriate FUNCTION_DECL.
        (is_overloaded_fn): Returns whether or not the passed tree is
        a function or list of functions.

        * cp-init.c (init_init_processing): use `get_first_fn' to find
        the FUNCTION_DEFN for new and delete.

        * cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
        code size in half (I spit on special cases).

Tue Sep  7 20:03:33 1993  Jason Merrill  (jason@deneb.cygnus.com)

        * cp-decl.c: Allow references and template type parameters as well
