Sun Jan 13 17:48:13 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)

        * version.c: Bump version number to 1.38.0.  Lots of work has been
        done on GNU C++ between August and January--but that work has been
        done to version 2.0, not to version 1.

Thu Aug 23 10:30:10 1990  Michael Tiemann  (tiemann at cygnus.com)

        * cplus-tree.h (CLASSTYPE_CID): Key off of TYPE_MAIN_VARIANT.

Sun Aug 19 09:58:16 1990  Michael Tiemann  (tiemann at cygnus.com)

        * stmt.c: Fixes from 2.0 for fixup_goto incorporated here.

        * cplus-decl2.c (write_vtable_entries): Don't test TREE_EXTERNAL
        of DECL_CONTEXT (FN).  TREE_EXTERNAL is not meaningful for types.

Wed Aug 15 15:50:36 1990  Michael Tiemann  (tiemann at cygnus.com)

        * dbxout.c (dbxout_type): Skip past const and volatile qualifiers
        that might appear in method names.

Mon Aug 13 10:14:37 1990  Michael Tiemann  (tiemann at cygnus.com)

        * cplus-decl2.c (flag_minimal_debug): Now is default is
        -fflag-minimal-debug.

        * cplus-tree.c (virtual_member): Return the assoc of a non-virtual
        basetype that comes from a virtual baseclass.  Changed callers
        which used to call `value_member' to call virtual_member instead.

Mon Aug  6 06:44:07 1990  Michael Tiemann  (tiemann at cygnus.com)

        * dbxout.c (dbxout_symbol): Send out tags before sending out
        types.  Also, handle getting rtl from inline functions.
        * dbxout.c (dbxout_parms): Get rtl from inline functions.
        * dbxout.c (dbxout_reg_parms): Ditto.

Sun Aug  5 00:04:08 1990  Michael Tiemann  (tiemann at cygnus.com)

        * Merged `g++field.tar.Z' from Brown.  Thanks to Steve
        Reiss (spr@cs.brown.edu) for these changes.

        * Merged `g++-for-pmax.diffs' from foobar.colorado.edu.
        Thanks to Dirk Grunwald (grunwald@foobar.colorado.edu)
        for making G++ work on the PMAX.

        * cplus-decl2.c (grokfield): It is no longer legal to specify
        the initializer for a static const member in the class
        declaration.  Dealing with default initializers is basically
        impossible.

        * cplus-init.c (build_delete): Don't wrap `addr' in a SAVE_EXPR
        until it is in fact an address.  This allows us to call
        destructors on the return values of function calls.

        * cplus-typeck.c (commontype): Fixed bug in OFFSET_TYPE case which
        led to infinite recursion (since we did not reduce the types
        before we recursed).

        * cplus-lex.c (check_newline): Make `#pragma implementation' more
        forgiving.

        * cplus-init.c (expand_aggr_init): Changed Jan 20th change so that
        we test whether TYPE has a constructor defined, and we do not test
        at all whether INIT was from a GNU constructor expression or not.

        * cplus-typeck.c (build_modify_expr_1): Don't return
        `error_mark_node' unless there really was an error.  If there is
        no work to do, return `integer_zero_node'.

        * cplus-class.c (propagate_basetype_offsets): Count the space
        between baseclasses, not just the space they occupy.

        * cplus-typeck.c (commontype): Don't drop the exceptions that are
        raised by functions and methods.

        * cplus-cvt.c (convert_to_real): Fix if/else level problem in
        case where EXPR is of aggregate type.

        * cplus-decl.c (finish_decl): Give users a chance to set a
        breakpoint before the initialization of an object takes place.

        * cplus-class.c (build_method_call): If the function we get is not
        directly from the object we have, call `convert_pointer_to' if the
        object uses multiple inheritance or virtual baseclasses.

        * cplus-typeck.c (build_binary_op_nodefault): Don't call
        `convert_to_pointer' with an argument that might be
        the integer zero.

        * cplus-method.c (hack_identifier): Look for DECL_REFERENCE_SLOT
        in RESULT_DECLs as well.

        * cplus-init.c (build_vec_delete): Don't forget to deallocate the
        container if requested.  Really use AUTO_DELETE and
        AUTO_DELETE_VEC with the same interpretation as `build_delete'
        gives to its AUTO_DELETE parameter.

Sat Aug  4 21:24:04 1990  Michael Tiemann  (tiemann at cygnus.com)

        * varasm.c (assemble_variable): Hack our way around the problem
        that static class members look like initialized variables for the
        purposes of establishing FIRST_GLOBAL_OBJECT_NAME.

        * cplus-lex.c (reinit_parse_for_method): Give error message for
        common mistake of forgetting the function body.

        * cplus-typeck.c (build_component_ref): Make better error message
        when field is not found.

        * cplus-class.c (finish_struct): TYPE_GETS_*_INIT_REF comes from
        members as well.

        * cplus-typeck.c (c_expand_return): Give warning about returning
        non-lvalues that come from functional casts.

        * cplus-search.c (get_base_distance): Changed to follow leftmost
        path only when PARENT == TYPE_MAIN_VARIANT (PARENT).

        * cplus-class.c (modify_vtable_entries): Call get_base_distance
        with 0 path_ptr, since we do not appear to use the path computed.

Sun Jul 22 12:04:43 1990  Michael Tiemann  (tiemann at cygnus.com)

        * cplus-except.c (cplus_expand_end_except): If the user gives a
        default handler, the exception is considered caught in that
        handler.
        * cplus-parse.y (except_stmts): Rest of fix went here, in DEFAULT
        case.

        * cplus-decl.c (finish_decl): Don't emit cleanups twice.

        * cplus-class.c (finish_struct_bits): Don't call
        `fixup_vbase_offsets'.
        * cplus-tree.c (fixup_vbase_offsets): #if 0 this function.

        * expr.c (expand_expr): Bug fix from Stephen Pope in LOOP_STMT
        handling of local variables.

        * cplus-cvt.c (build_default_binary_type_conversion): Handle
        arguments which are REFERENCE_TYPE.

        * cplus-method.c (prepare_inline): Set DECL_CONTEXT of this
        function's parameters.

        * cplus-decl.c (grokfndecl): When adding a new virtual function
        entry, RAISES may change a second time.

Thu Jul  5 10:44:39 1990  Michael Tiemann  (tiemann at masham)

        * cplus-decl2.c (grokfield): Static consts need not be initialized
        in the class definition.

Mon Jul  2 06:12:49 1990  Michael Tiemann  (tiemann at masham)

        * cplus-init.c (resolve_offset_ref): If BASETYPE is not a base
        type for the current class, give error and return.

Sun Jul  1 00:18:47 1990  Michael Tiemann  (tiemann at masham)

        * cplus-decl.c (finish_function): Throw away more code if we have
        an inline function from the interface.

        * dbxout.c (dbxout_tags): Further reduce the amount of debugging
        information written out for class types.

        * cplus-class.c (add_virtual_function): Set DECL_VINDEX from the
        virtual function which comes from the vtable shared by
        CURRENT_CLASS_TYPE, if possibe.

        * cplus-typeck.c (build_binary_op): Call `default_conversion'
        after doing type instantiation.

        * cplus-init.c (build_new): New 2.0 interpretation: `new int (10)'
        means allocate an int, and initialize it with 10.

        * cplus-init.c (emit_base_init): Completion of fix for virtual
        function table initialization.  @@ BTW, this may now cause extra
        virtual function table initializations.  They will all be correct,
        but they may also be redundant.  GCC's optimizer doesn't know how
        to remove even the simplest such redundancy.

Sat Jun 30 13:54:30 1990  Michael Tiemann  (tiemann at masham)

        * cplus-class.c (finish_base_struct): Store BASETYPE in the
        VFIELDS chain (in its TREE_TYPE).

Fri Jun 29 09:26:17 1990  Michael Tiemann  (tiemann at masham)

        * cplus-class.c (build_vtable,prepare_fresh_vtable): Stash the
        type that caused this vtable to be defined in DECL_CONTEXT
        * cplus-search.c (bfs_unmark_finished_struct): Work around
        DECL_CONTEXT conflict for vtables.  @@ NOT A SOLUTION.

        * cplus-lex.c: Extend meaning of `#pragma implementation'
        to allow files to `implement' types from general headers.

Thu Jun 28 17:35:04 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-typeck.c (build_vbase_vtables_init): Fixed typo in code
        that bashes LHS references.

Wed Jun 27 00:12:24 1990  Michael Tiemann  (tiemann at masham)

        * cplus-decl.c (pushdecl): To warn about parameter shadowing, must
        look two levels up, not one.

        * cplus-search.c (build_vbase_vtables_init): Add new parameter
        CTOR_P which says whether we can use computed offsets to store
        vtables into virtual sub-objects, or whether we should use
        existing vbase pointers.

        [Wrong fix: * cplus-cvt.c (convert_from_reference): Don't convert
        from a reference to an incomplete type.]
        * cplus-typeck.c (build_modify_expr): Give error if using a
        reference to an incomplete type.

        * cplus-class.c (pushclass): Eliminate fencepost error.  Also,
        realloc allocation unit is byte, not whatever the type of the
        array happens to be!

Tue Jun 26 04:28:00 1990  Michael Tiemann  (tiemann at masham)

        * expr.c (expand_expr): Mark all {VAR,FUNCTION,CONST}_DECL nodes
        that go through `expand_expr' as used.

        * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').

Mon Jun 25 01:39:53 1990  Michael Tiemann  (tiemann at masham)

        * dbxout.c (dbxout_type): Fix confusion that was causing
        debugging information about constructors (for classes which did
        not have destructors) to be omitted.  Also, simplify some code.

Sat Jun 23 12:32:38 1990  Michael Tiemann  (tiemann at masham)

        * cplus-lex.c (interface_strcmp): Fix braino.

        * cplus-decl.c (finish_function): Make all virtual function table
        pointers point to CURRENT_CLASS_TYPE's virtual function tables.

Fri Jun 22 08:28:07 1990  Michael Tiemann  (tiemann at masham)

        * cplus-init.c (build_member_call): Handle case where NAME refers
        to a member (instead of a member function) and try calling
        overloaded CALL_EXPR.

        * cplus-decl.c (maybe_build_cleanup): If a destructor is defined
        for the type, the destructor will take care of deleting all the
        virtual baseclasses.

        * cplus-init.c (emit_base_init,expand_recursive_init_1):
        Initialize virtual function table pointers of non-leftmost,
        non-virtual baseclasses. 

        * cplus-class.c (ideal_candidate): Each TREE_VALUE (TTA) must
        be reset from TREE_PURPOSE (TTA), whether or not that particular
        TREE_VALUE was the result of a type conversion for the particular
        candidate we are returning--the TREE_VALUE may have been trashed
        by a (failed) type conversion for some other candidate.

        * cplus-typeck.c (c_expand_result): Set TREE_VOLATILE bits of
        RESULT when initializing a temporary.

Thu Jun 21 09:14:06 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-lex.c (check_newline): Handle case where #pragma
        interface/implementation is given, but no #line precedes it.

        * cplus-decl.c (start_function): If DECL1 is an inline function
        belonging to an implemenation (as opposed to an interface), make
        it public.

Tue Jun 19 13:55:13 1990  Michael Tiemann  (tiemann at teacake)

        * version.c: Changed version number to 1.37.2 alpha 2.

Fri Jun 15 03:19:50 1990  Michael Tiemann  (tiemann at masham)

        * cplus-search.c: No longer any need for VBASE_CHAR_STAR.  Use
        VBASE_DECL_PTR in its stead.

        * cplus-search.c (dfs_init_vbase_pointers): Use values computed in
        CLASSTYPE_SEARCH_SLOT when casting to virtual baseclasses.  Only
        call `convert_pointer_to' in this function when we will *not* be
        going through a virtual baseclass pointer.  The change was needed
        because we might have a class hierarchy with multiple virtual
        baseclasses, and in an effort to initialize first the most-base
        virtual baseclass, the compiler would generate code that would
        errantly try to get there via a not-yet-initilized intermediate
        virtual baseclass pointer.

        * cplus-init.c (build_new): Don't let PENDING_SIZES be expanded
        immediately during this function.  The result of calling this
        function should only build tree nodes, not emit any insns.

        * cplus-decl.c (grok_enum_decls): If TYPE is not in scope, give
        reasonable default behavior (instead of aborting).

        * cplus-class.c (build_method_call): Fix typo in case vtable is
        not needed.

Wed Jun  6 10:13:53 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-typeck.c (build_modify_expr): Stabilize LHS and RHS if
        neccessary.

        * cplus-cvt.c (build_type_conversion): Don't convert to `void *'
        unless this is a CONVERT_EXPR.

Tue Jun  5 07:52:36 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-class.c (finish_struct): Must set CLASSTYPE_INTERFACE_ONLY
        and CLASSTYPE_VTABLE_NEEDS_WRITING bits before building the
        virtual function table.

        * cplus-lex.c (interface_strcmp): Modified to discard path
        prefixes before comparing filenames.

Mon Jun  4 06:32:59 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-decl.c (finish_function): Test HAVE_return.  Now needs
        on insn-flags.h.
        * Makefile: Depend cplus-decl.o on insn-flags.h.

        * cplus-parse.y (except_stmts): Use gotos and labels to implement
        default actions instead of wrapping it in an RTL_EXPR and emitting
        it at the end.  This is intended to cause the debugger less grief.

Sat Jun  2 13:45:45 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-class.c (build_scoped_method_call): Give error if EXP is
        not of aggregate type.

        * cplus-typeck.c (build_x_function_type): Don't be fooled by case
        where parser thinks we have a method involving `this' (when we
        really don't).

        * cplus-decl.c (pushdecl): Use `lang_printable_name' on T instead
        of printing directly from IDENTIFIER_POINTER (NAME).

        * cplus-init.c (expand_aggr_init_1): Code which is supposed to
        print error message was not, because FLAGS passed to
        build_method_call were not in synch with PARMS
        (LOOKUP_HAS_IN_CHARGE was accidently missing from FLAGS).

        * cplus-init.c (build_new): Fix obscure bug where a object needing
        larger than word alignment was getting memory at the wrong
        address.

        * expr.c (expand_expr): In LET_STMT case, expand initializers for
        VARS, whether or not their RTL has already been defined.

        * cplus-class.c (instantiate_type): If there's only one function
        we know about, and its global, return that.

        * cplus-decl.c (finish_decl): Check more cases for uninitialized
        consts.

        * cplus-method.c (fndecl_as_string): Get past the `in_charge' node
        if a constructor uses virtual baseclasses.

        * cplus-init.c (build_delete): If we are destroying base part of
        the object, call with ADDR and the pointer to the base type
        instead of calling with REF and the base type.  This is because
        REF may not be stable (or seemingly addressable), whereas ADDR is
        fine and dandy.

        * cplus-decl.c (grokdeclarator): Don't accept friend declarations
        not in class definitions.

        * cplus-decl2.c (grokbitfield): Don't die if user tries to declare
        a bitfield type.

        * cplus-decl.c (add_block_current_level): New function.
        * cplus-parse.y (except_stmts): In DEFAULT case, if `compstmt' was
        empty, cons up a block (a LET_STMT) and add it to the current
        level.

        * cplus-parse.y (except_stmts): Set TREE_LANG_FLAG_2 of `compstmt'
        when in the default section of the catch clauses.

        * All GNU C++ files: rename functions from expand_cplus_... to
        cplus_expand_...

        * dbxout.c (dbxout_{try,ehdecl,catch,end_catch_clauses}): New
        functions to write out symbol information for exception handling.
        (Based on TREE_LANG_FLAGs of blocks).

        * cplus-except.c: Added code to set TREE_LANG_FLAGs of blocks that
        are returned from `poplevel'.  TREE_LANG_FLAG_1 means a try block;
        TREE_LANG_FLAG_2 means a catch block; TREE_LANG_FLAG_3 means an
        except block (which also means the end of the catch blocks).
        * cplus-parse.y: Ditto.

        * cplus-typeck.c (build_binary_op): In addition to NE_EXPR
        comparison against INTEGER_ZERO_NODE, also allow EQ_EXPR for
        allowable pointer conversions.

        * cplus-cvt.c (build_type_conversion): Check that a conversion is
        not ambiguous (error_mark_node) before using it immediately.

        * cplus-class.c (ideal_candidate): Don't quit immediately if the
        parameters of the derived conversion to not match the parameters
        of the base conversion.

Tue May 22 06:06:38 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-cvt.c (convert_from_reference): No longer try to optimize
        case of pulling known value from reference.  We may want to do
        this later, but it's not worth debugging now.

        * cplus-decl.c (grok_reference_init): Only build temporary for
        reference initialization if the reference type is `const'.
        (New ANSI C++ rules).  Also, change interface to return `void',
        since it was always returning 0.  Change caller to set INIT to 0
        after calling `grok_reference_init'.

Fri May 18 14:05:38 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-class.c (build_vbase_path): Avoid crash in case syntax
        errors got things confused and we can't find our virtual
        baseclass.

Mon May 14 07:52:22 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-class.c (build_method_call): Don't use a virtual function
        table if INSTANCE is manifestly `this' in constructor or
        destructor.

        * cplus-init.c (build_delete): Major interface change.
        AUTO_DELETE now has additional possible values.  If in the
        program, (AUTO_DELETE & 1) is non-zero, then call free on our
        incoming object.  If (AUTO_DELETE & 2) is non-zero, then tear down
        virtual baseclasses as well.  All callers changed.

Sun May 13 15:57:48 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-parse.y (delete cast_expr): If the type of object being
        destroyed has a destructor, then give the destructor full
        authority to destroy the object.  This will include destroying its
        virtual base classes.  If the type does not have a destructor
        (cannot have multiple or virtual baseclasses in this case), then
        perform the two-step process of destroying and then deallocating
        the object.  Also add LOOKUP_HAS_IN_CHARGE to the flags we use in
        our call.

        * cplus-decl.c (finish_function): Make sure to call the delete
        operator when finished inside a destructor.

        * cplus-init.c (build_delete): Don't change the vtables of the
        object being deleted here.
        * cplus-decl.c (finish_function): Change them all here (not just
        virtual baseclasses).  Uses CLASSTYPE_VFIELDS to find all the
        vfield slots.

Sat May 12 08:13:44 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-typeck.c (build_x_compound_expr): New function to be
        called when syntactic ',' operator is parsed.
        * cplus-parse.y (expr): Call `build_x_compound_expr' instead of
        build_compound_expr'.
        * cplus-lex.c (init_lex): Prepare to handle operator,.

        * dbxout.c (dbxout_type_fields): Write out anonymous union
        elements.

        * cplus-typeck.c (build_modify_expr): Handle case of op= where
        operands require type conversion to some scalar reference type.

        * cplus-parse.y (do_components): Give parse error if type
        declaration in structure is not one of ENUMERAL_TYPE, UNION_TYPE,
        or RECORD_TYPE.

        * cplus-typeck.c (build_modify_expr_1): Effort to save a tree node
        by copying a subexpression and assigning its type got GNU C++ in
        trouble.  Code now assigns the baseclasses via `get_base_ref'.
        (get_base_ref): New function.

        * cplus-lex.c (interface_strcmp): New function.  Handle all files
        whose prefix matches the initial file's prefix.  A prefix in this
        case is the string of characters up to the first `.'.

        * cplus-decl.c (grok_reference_init): If the type of the
        initializer has the same code as the type of the reference,
        convert the initializer to the reference's target type.  This
        permits people to say things like `short &sr = 10;'.

        * cplus-cvt.c (convert_to_reference): Don't convert types whose
        sizes or codes are different (if both are non-aggr type).

        * cplus-typeck (build_binary_op_nodefault): Call
        `common_base_type' when comparing pointers with EQ_EXPR or
        NE_EXPR.

        * cplus-typeck.c (build_conditional_expr): if TYPE1 and TYPE2
        share a common ancestor, then convert to this type instead of
        giving type mismatch error.
        (common_base_type): New function.

Fri May  4 00:13:44 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-decl2.c (finish_file): TREE_PUBLIC is enough to cause
        vtable to be written out if WRITE_VIRTUALS > 0.

        * cplus-class.c (prepare_fresh_vtable): Set TREE_PUBLIC and
        TREE_EXTERNAL here according to CLASSTYPE_VTABLE_NEEDS_WRITING, 
        etc.

        * cplus-typeck.c (commonparms): Free space used by common
        parameter list if there were no changes needed to merge P1 and P2.

Thu May  3 22:56:46 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (expand_member_init): Don't be faked out by names
        which are both typedef'd and which are class members.  In the
        future, we need to handle the whole namespace problem better, but
        for now, if it doesn't look like a base type, treat it as a
        member.

        * cplus-typeck.c (commonparms): New function; consists of code
        split out from `commontype'.
        * cplus-decl.c (grokfndecl): Call `commonparms' to merge default
        parameter information from base class into derived class virtual
        function.

Wed May  2 22:28:51 1990  Michael Tiemann  (tiemann at teacake)

        * dbxout.c (dbxout_type): Don't convert DECL_OFFSET (TYPE_NAME (TYPE)) 
        to bits from bytes--it is already in bits.

Sun Apr 29 00:01:56 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-decl2.c (finish_file): Continue with substitution of
        `build' with `build1' where appropriate.
        * cplus-init.c (various places): Ditto.

Sat Apr 28 14:32:42 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-decl.c (maybe_build_cleanup): Call `build1' instead of
        `build'.
        * cplus-expr.c (cplus_expand_expr): Ditto.
        * expr.c (various places): Ditto.
        * cplus-typeck.c (Ditto): Ditto.

        * New strategies for saving storage and time:
        * cplus-tree.c (list_hash_lookup_or_cons): Look into VALUE to see
        if we have a list of the kind we want.  If we don't put the list
        into HASH_LIST_TABLE.
        * cplus-tree.c (build_decl_list_1): Same strategy, but cons
        a temporary node if we don't.
        * cplus-parse.y: Call `build_decl_list_1' where profitable.
        * cplus-decl.c (grokdeclarator): Handle missing declarator names
        more gracefully.
        * cplus-decl2.c (groktypefield): Handle a RECORD_TYPE in
        DECLSPECS.

Thu Apr 26 18:25:31 1990  Michael Tiemann  (tiemann at teacake)

        * Merged changes to make #pragma dump and -fundump-... work with
        #pragma interface and #pragma implementation.  Also, use mmap on
        Sun instead of reading all bits from a dumped file.

Wed Apr 25 10:06:44 1990  Michael Tiemann  (tiemann at teacake)

        * toplev.c (rest_of_compilation): Rewire inline logic to avoid
        most calls to `save_for_inline'.
        * integrate.c (save_for_outline): New function; saves functions
        which are normally inline, but may need to be outlined later.

        * cplus-tree.c (layout_basetypes): Clear CLASSTYPE_VIA_VIRTUAL if
        BASETYPE is incomplete.

        * cplus-tree.h: Change respresentation of `type_lang_specific' to
        keep conversions in array rather than in separate variables.
        * cplus-tree.h: Use enum conversion_type to index into the
        conversion array.
        * cplus-class.c: Replace random logic with loop that iterates
        across conversion types.

Tue Apr 24 00:36:02 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-decl{2}.c: Finally get #pragma interface and #pragma
        implemenetation working.

        * cplus-{decl2,lex,init,method}.c: "__user_new" is gone.  It has
        been replaced uniformly with OPERATOR_NEW_FORMAT.
        * cplus-init.c (build_new): Parameter USER_PARMS is renamed
        PLACEMENT.

        * cplus-parse.y (primary): Handle case where `operator_name' is an
        here-to-fore unknown operator.
        * cplus-class.c (build_instantiated_decl): Pass &EXP instead of
        &TREE_VALUE (EXP) to `build_operator_fnname'.  All other calls to
        that function pass the address of an OP_IDENTIFIER.

        * cplus-decl.c (finish_function): Call `convert_pointer_to_vbase'
        instead of `convert_pointer_to'; this saves an abort when the
        lattice contains both virtual and non-virtual versions of a
        baseclass we are looking for.

        * cplus-decl2.c (setup_vtable_pointer): Cast initializer to
        CURRENT_VTABLE_DECL in case it is more basic than we want it.

        * cplus-typeck.c (build_c_cast): Handle casting one reference type
        to another.

        * cplus-cvt.c (build_type_conversion): More creativity in ways of
        finding type conversions.

        * cplus-typeck.c (build_binary_op): Code simplified.

        * cplus-class.c (build_vbase_path): Incorprate Vasta's fix which
        resets CODE to PLUS_EXPR once we have used it.  Otherwise, OFFSET
        might be twice negated.

        * cplus-typeck.c (build_modify_expr): Since we don't know about
        potential aliases, unless -felide-constructors is set, treat
        "x = F(y);" as "t = F(y), x = t" if x's TREE_TYPE is
        TREE_ADDRESSABLE.

        * cplus-decl.c (finish_function): If CLEANUP_LABEL is non-zero,
        effectively do a jump to RETURN_LABEL in case the user has -Wall
        turned on.  This causes the right things to happen to
        NOTE_INSN_FUNCTION_END.

        * cplus-decl.c (grokvardecl): Give error if static member is
        multiply initialized.  `duplicate_decls' will never be called for
        this case, hence it cannot warn us.

        * cplus-decl.c (grokdeclarator): CONSTP is meaningless for
        REFERENCE_TYPEs.

        * cplus-typeck.c (actualparameterlist): Don't make an OFFSET_REF
        of something that is already an OFFSET_REF.

Sun Apr 22 18:38:35 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-method.c (build_opfncall): ARG3 holds the PLACEMENT of a
        user-defined new operator.

        * cplus-init.c (build_new): Interface change now takes
        USE_GLOBAL_NEW as parameter.  All callers changed.

Wed Apr 18 10:10:09 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-search.c (dfs_record_inheritance): Use TYPE_MAIN_VARIANT
        of BASECLASS.

        * cplus-search.c (report_ambiguous_mi_virtuals): Don't crash if
        MI_VMATRIX is not fully populated (i.e., there are zero entries in
        between non-zero ones).

Fri Apr 13 09:07:36 1990  Michael Tiemann  (tiemann at suntana)

        * expr.c (expand_call): Don't defer popping if this is a call to
        setjmp, longjmp (or a related function).

Wed Apr 11 09:49:33 1990  Michael Tiemann  (tiemann at gzilla)

        * cplus-typeck.c (build_component_ref): When taking address of
        bound member function, don't forget to convert DATUM to
        DECL_VCONTEXT of FIELD.

Sat Apr  7 12:49:13 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-search.c (get_first_matching_virtual): Don't crash if
        redeclaring a virtual function `static'.

Thu Apr  5 04:45:13 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-class.c (finish_struct): Remove warning about structures
        which have no data members.

        * expr.c (expand_expr): Do not call `use_variable' on a TYPE_DECL
        of STMT_VARs.

Tue Apr  3 07:48:47 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-typeck.c (c_expand_start_case): Make this function handle
        expressions that can be converted to integer types via type
        conversion operators.

        * cplus-decl.c (start_function): If there was a previous `extern "C"'
        declaration when a function is defined in C++ langauge scope, give
        error message if argument types line up, but return types do not.

Mon Apr  2 13:38:22 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-lex.c (check_newline): Recognize `#pragma interface'.
        * cplus-tree.c (lang_output_debug_info): Implement action for
        `#pragma interface'.
        * cplus-decl{2}.c: Various hacks to make this work.

        * cplus-class.c (finish_struct): Added new slots for
        CLASSTYPE_INT_CONVERSION and CLASSTYPE_REAL_CONVERSION to simplify
        picking up these conversions when narrower or wider conversions
        (than the default type) are provided.

        * cplus-cvt.c (build_up_reference): When building `X&' via an
        `operator X ()', build it into a temporary, and return the
        COMPOUND_EXPR which first computes the conversion and second has
        the value of the temporary's address.

Sun Apr  1 17:28:35 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-decl.c (build_enumerator): Handle case where VALUE is a
        constant VAR_DECL.

Fri Mar 30 02:16:34 1990  Michael Tiemann  (tiemann at arkesden)

        * cplus-class.c (build_{scoped_}method_call): Handle calls to
        destructor according to anticipated ANSI C++ rules.  p->X::~X ()
        should call destructor (without calling `operator delete').
        p->~X () should do likewise, but use a virtual lookup (perhaps).

        * cplus-class.c (compute_conversion_costs): Permit conversion to
        `X&' when only `operator X' exists.

Thu Mar 29 18:14:31 1990  Michael Tiemann  (tiemann at rio)

        variables are not used before they are initialized.
        * All callers changed.

Wed Mar 28 17:27:37 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (build_new): If space is allocated for constructor,
        call `build_method_call' with flags saying that the constructor is
        in charge.

Tue Mar 27 22:20:37 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (build_virtual_init): Convert virtual function
        table address to type of virtual function table pointer.  These
        may now compare as different, since array sizes between base and
        derived classes may be different.

        * cplus-parse.y (init_parse): Make room for ENDFILE, which has the
        value (-1).

Mon Mar 26 09:00:27 1990  Michael Tiemann  (tiemann at teacake)

        * toplev.c (FLAG_INLINE_DEBUG): New flag to control whether
        inlines get debugging information or not.
        * cplus-decl2.c (LANG_F_OPTIONS): Implemented.
        * integerate.c (expand_inline_functions): Implemented.
        * cplus-except.c (init_exception_processing): Make it possible for
        user to declare `exceptionHandlerStack' her/himself.

Sun Mar 25 05:04:06 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (build_delete): Remove assertion that
        CLASSTYPE_OFFSET of BASETYPE must be non-zero for baseclasses 2
        through N.  The first non-virtual baseclass need not be the first
        baseclass, and it will be the one with a zero offset.

        * cplus-except.c (call_to_unhandled_exception): Adjust length
        argument to `build_string'.

        * cplus-dem.c: Apply James Clark's patches.

        * cplus-decl.c (start_decl): If DECL is static and non-permanent,
        and DECL needs destroying, make DECL permanent.  If there are
        components of DECL's type which need to be made permanent, make
        them permanent as well.

        * cplus-decl.c (grokdeclarator): Fix bugoid in SCOPE_REF case.

        * cplus-decl.c (finish_decl): Wait to build CLEANUP from DECL
        until after completing its array type.

        * cplus-typeck.c (build_unary_op): If ARG is an OFFSET_REF,
        resolve it before trying to increment (or decrement) it.

        * cplus-class.c (finish_struct_bits): When looking for type
        conversion operators, test METHOD_VEC against NULL_TREE (in case
        there is a conversion from a base class, and the derived class
        defines no methods).

        * cplus-cvt.c (build_up_reference): Don't try to build up a
        reference to an aggregate type which is not derived from another.

        * cplus-type2.c (build_functional_cast): Fixed typo.

        * cplus-typeck.c (comptypes): Break out code for ARRAY_TYPE case.
        * cplus-typeck.c (comp_array_types): Function for that code.
        * cplus-typeck.c (comptypes,comp_target_types): Call
        `comp_array_types' for ARRAY_TYPE case.

        * cplus-class.c (build_method_call): Don't give error if
        LOOKUP_COMPLAIN is not in FLAGS.

        * cplus-init.c (expand_aggr_init_1): When looking for
        constructors, if XXREF_INIT_POSSIBLE is LOOKUP_SPECULATIVELY,
        clear out LOOKUP_COMPLAIN, since failure of a particular
        constructor can be managed by performing X(X&) initialization.  If
        that fails, the caller of that attempted initialization will give
        the error message.

        * cplus-decl2.c (coerce_delete_type): Simplify code, and make it
        work in the presence of delete type with TYPE_ARG_TYPES (type) ==
        NULL_TREE.

        * tree.c (array_type_nelts): Give error if this function is called
        with incomplete type.

Sat Mar 24 19:23:19 1990  Michael Tiemann  (tiemann at teacake)

        * stmt.c (expand_function_start): Emit note that parms are in
        their homes.

        * cplus-typeck.c (build_unary_op): Function types can have unary
        `!' applied to them.

        * stmt.c (expand_expr_stmt): Don't warn about unused expressions
        that are explicitly cast to void.

Sat Mar 10 05:23:36 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-lex.c (reinit_parse_for_method): Try to give user some
        clue as to where the problem is if method declaration looks wrong.

        * Makefile: Better handling of cadillac vs non-cadillac
        compilation.
        * cplus-cadillac.c: Updates for latest protocol.

        * cplus-cvt.c (build_type_conversion): Don't crash if EXPR is
        ERROR_MARK_NODE.

        * cplus-class.c (build_method_call): Check for return of
        `error_mark_node' from call to `build_new'.

        * integrate.c (expand_inline_function): Forget about register
        constancy if somebody clobbers a part of the register via a
        STRICT_LOW_PART, SUBREG, SIGN_EXTRACT or ZERO_EXTRACT operation.

        * integrate.c (output_inline_function): LAST was unitialized due
        to #if 0.  Moved #if 0 inside of loop.

Sun Mar  4 04:12:53 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (build_new): Unless eliding constructors, we must
        go through constructors if they are defined.

        * cplus-decl.c (start_function): Protect binding level of parms by
        calling `pushlevel' in here...
        * cplus-decl.c (finish_function): ...instead of here.  Make sure
        we call corresponding `poplevel' on both constructor paths.

        * cplus-init.c (finish_base_init): If handling exceptions for
        Spring, must always have IN_CHARGE_IDENTIFIER doing its thing for
        constructors.

        * cplus-except.c (finish_exception_decl): Don't pretend that CTOR
        is not a constructor.

        * cplus-decl.c (start_function): Force constructors to `return'
        via CTOR_LABEL.

        * cplus-decl.c (init_decl_processing): If handling exceptions for
        Spring, set FLAG_THIS_IS_VARIABLE to 2.

        * cplus-except.c (expand_cplus_reraise): Handle case where
        EXCEPTIONS is an exception object to be reraised.

        * integrate.c (copy_decl_tree): Try latest fixes for GCC 2.0 to
        improve GNU C++'s handing of inline functions.

        * cplus-init.c (expand_aggr_vbase_init): Delete this function
        static.

        use precisely the right baseclass in the TREE_PURPOSE slot.
        * cplus-class.c (modify_vtable_entries): Add additional test of

        basetype that TREE_VALUE (VSLOTS) is.

        * cplus-decl.c (finish_decl): If ASMSPEC_TREE is non-zero, then
        zero out DECL_RTL (DECL).  Otherwise, it won't take.

        * cplus-except.c (expand_cplus_end_catch): Call `expand_end_catch'
        instead of `expand_escape_except'.

        unhandled exceptions, have the program call
        `__unhandled_exception' instead of `abort'.

        * cplus-class.c (ideal_candidate): If the best candidate requires
        a strict subset of the user-defined type conversions of all the
        other candidates, pick it as the best.

        * cplus-type2.c (build_functional_cast): If both attempts to cast

        * stor-layout.c (layout_{record,union}): For loops over fields,
        skip if TREE_CODE (field) != FIELD_DECL, instead of testing if ==
        CONST_DECL or VAR_DECL or TYPE_DECL etc.

        * cplus-decl.c (pushtag): Do gratuitous C++ typedefing even when
        in C language scope.  Sigh.

        * cplus-decl.c (xref_tag): Don't assume CODE == TREE_CODE (REF).
        It's not when the user redeclares REF as the wrong kind of tag.

        don't try for fancy constructors.

        * cplus-decl.c (build_enumerator): TREE_TYPE (VALUE) must always
        be INTEGER_TYPE_NODE before calling `build_binary_op_nodefault'.

        T uses virtual baseclasses or multiple inheritance, in addition to
        the usual cases.

        * integrate.c (copy_rtx_and_substitute): If we were needing an
        inline target (for example, a USE of the function return result),
        and we don't have one, just cons one up.

        * cplus-init.c (expand_vec_init): Comparison of HOST_I against
        zero should have been >=, not >.

        * cplus-dem.c: Fix #defines to use bcopy, bcmp instead of the str
        functions.

        * cplus-cvt.c (convert): If converting to void type, check for
        possible operator void.

        * stmt.c (fixup_cleanups): If cleanups expand to nothing, don't
        call `reorder_insns'.

        Abstracts functionality of pushing/popping objects to/from
        obstacks.
        * cplus-search.c ({push,pop}_search_level): Use new *_stack_level
        functions.

Tue Feb 13 11:32:12 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-init.c (build_delete): This function can get visibilities
        wrong if default destructors are not built (currently the case).
        As a temporary fix, pass FLAGS with LOOKUP_PROTECTED_OK for base
        destructor calls, and test LOOKUP_PROTECTED_OK when thinking about
        complaining.

Sun Feb 11 11:47:37 1990  Michael Tiemann  (tiemann at arkesden)

        * cplus-decl.c (finish_function): Don't call `build_virtual_init'
        for types which don't have virtual functions.  Similarly, don't
        call `build_delete' if it doesn't need a destructor.

        * cplus-init.c (finish_base_init,build_delete): When building up
        and tearing down objects' bases, build pointers to base objects
        directly rather than by calling through `convert_pointer_to',
        since ambiguity in the lattice causes it trouble.

        * cplus-typeck.c (build_modify_expr): Removed unneeded casts when
        building sum of base address + offset.
        * cplus-class.c (build_vbase_path): Ditto.

        * cplus-typeck.c (build_modify_expr): Fix parenthesis error for
        deciding whether to recurse through aggregates or not
        (TYPE_USES_VIRTUAL_BASECLASSES is not enough).

        * cplus-parse.y (try): Change type from TTYPE to ITYPE.
        * cplus-parse.y (stmt): Call `cplus_expand_end_try' with result of
        `try' stmt.  Now, if we wanted to, we could pass additional
        information about whether this try block is followed by an except
        stmt or a reraise clause.
        * cplus-parse.y (stmt): When processing a reraise clause, use
        ERROR_MARK_NODE as the default handler, to indicate that we
        actually have one, rather than NULL_TREE, which claims that we
        don't.
        * cplus-except.c (cplus_expand_end_except): Always try next
        handler before ending the block.

        * cplus-init.c (build_delete): Use `convert_pointer_to' when ADDR
        is TREE_LITERAL.

        * cplus-class.c (build_vfn_ref): Save intermediate result in
        SAVE_EXPR so we don't have to compute each component of virtual
        function pointer twice.  But only do this when BUILDING_CLEANUP
        is zero.
        * cplus-decl.c (maybe_build_cleanup): New global variable
        BUILD_CLEANUP is controlled by this function.

        * cplus-expr.c (cplus_expand_expr): Use separate CALL_TARGET and
        RETURN_TARGET, in case call to `expand_expr' returns something
        different than CALL_TARGET in NEW_EXPR case.

Fri Feb  9 04:00:42 1990  Michael Tiemann  (tiemann at teacake)

        * cplus-lex.c (getch): New function.  Encapsulates call to `getc'

        * cplus-lex.c (check_newline): Call `getch' instead of `getc' to
        get pragma text.

        proper initial value for OFFSET.

        * cplus-tree.c (layout_vbasetypes): Gross error was accidently
        causing storage to be exponentially counted!  Fixed...

        * cplus-decl.c (duplicate_decls): Catch case where OLDDECLS are
        some overloaded functions and NEWDECL is not a FUNCTION_DECL.

        * cplus-init.c (finish_base_init): If there are several members
        with the same name (from different baseclasses), get the topmost
        one.

        * cplus-tree.c (lang_simple_cst_equal): New function.  Callback
        for `simple_cst_equal'.
        * tree.c (simple_cst_equal): Needs new treatment for handling
        NEW_EXPR and CPLUS_NEW_EXPR.  Use call-back for latter.
        * tree.c (simple_cst_list_equal): Now non-static.

        * integrate.c (expand_inline_function): Use `convert_move' instead
        of `emit_move_insn' when we need to copy INLINE_TARGET back to
        TARGET.

Sat Feb  3 09:45:47 1990  Michael Tiemann  (tiemann at teacake)

        * version.c: version 1.36.4 released.

        * cplus-decl.c (build_enumerator): Make it impossible to lose if
        ENUM_NEXT_VALUE is something like INTEGER_ONE_NODE.

        * tree.c (build_int_2): Don't need to set TREE_LITERAL here, it is
        set in `make_node'.
        * tree.c (make_node): Increment `TREE_NODE_KINDS[C_KIND]' for
        INTEGER_CST nodes.

        * cplus-init.c (expand_aggr_init_1): NEW_EXPR now encapsulates new
        information (due to compiler merging); lossage fixed.

        * case.c (various places): Replace calls to `build_int_2 (x, 0)'
        (where x == 0 or x == 1) with INTEGER_{ZERO,ONE}_NODE as
        appropriate.

        * cplus-typeck.c (build_component_addr): Break out code to build
        the ADDR_EXPR of a COMPONENT_REF from `build_unary_op'.

        IF_STMT, or LET_STMT.

        * cplus-decl.c (build_enumerator): Prepare for fact that `fold'
        might put NOP_EXPRs around everything that is not an lvalue.

        * cplus-method.c (build_opfncall): New parameter FLAGS.
        Don't lose unless FLAGS include LOOKUP_COMPLAIN; there's always a
        chance that a type conversion will work, after all.
        * All callers changed.

        * cplus-cvt.c (build_type_conversion): Permit `operator int' to
        convert when `unsigned' is wanted (provided no `operator unsigned'
        exists).  Same for `long' and `unsigned long'.

        * cplus-expr.c: New file.  Contains definition of new function
        `cplus_expand_expr'.

        * cplus-lex.c (init_lex): Initialize LANG_EXPAND_EXPR.

        * tree.c (decl_type_context): Handle LET_STMT.

        * stmt.c (expand_catch): Renaming of function
        `expand_start_catch'.  This function no longer takes EXITFLAG or
        ESCAPEFLAG as parameters (which is just as well, since it never
        used them anyway).
        * cplus-except.c (expand_cplus_start_catch): Caller changed.
        * cplus-parse.y: Removed vestigial call to `expand_end_catch'.

        * cplus-decl.c (duplicate_decls): Use FUNCTION_SIZE as measure of
        size of FUNCTION_DECL.

        * cplus-class.c (finish_base_struct): Get a fresh assoc list for

        its assoc list for sure.

        the lowering so that we don't get multiple calls to
        `build_vbase_path' when we try to build the vbase pointer.
        @@ This could probably be solved more cleanly.

        @@ Note that COMPONENT_REFs used as instance variables in method
        calls lose the fact that they were of fixed type.

        virtual function tables when some baseclasses are virtual.

        whether or not PATH_PTR is non-NULL.

        DATUM to the right address.

        * cplus-typeck.c (build_unary_op): Handle case where FIELD is
        really a TYPE_DECL (which is used just for its DECL_OFFSET).

        The following changes are for merged GCC/G++.  Changes marked
        with `@' had to be backed out.
        @ cplus-init.c (expand_delete): Deleted.

        `build_delete' rather than building up structure with DELETE_EXPR.

        * cplus-decl.c (finish_function): At end of destructor, no need to
        cast down the virtual function table if there is no virtual

        * cplus-decl.c (FLAG_INT_ENUM_EQUIVALENCE): New variable, controls
        how ints and enums should interconvert.

        that flag.

        * cplus-class.c (build_method_call): alloca `harshness' field of

        * cplus-class.c (build_overload_call): Don't alloca `harshness' of
        FINAL_CP, since caller does this.  Also, use `oballoc' for
        `harshness' arrays of CP array when running the list of functions
        to try.

        * cplus-method.c (hack_identifier): Use `error', not
        `error_with_decl' to report visibility violation for static
        members.  Also, compute visibility with `compute_visibility'.

        handling NEW_EXPR.

        * cplus-init.c (expand_aggr_init): When initializing from a

        defined or not: just strip out the elements as though they were
        args to a constructor and proceed.

        * cplus-class.c (build_method_call): If we need the address of a
        CONSTRUCTOR, initialize a fresh temporary, as in the NOP_EXPR

        * cplus-decl.c (grokdeclarator): If QUALS is non-NULL, don't abort

        COMPONENT_REF, must convert the base to the pointer type of the

Sat Jan 13 00:17:25 1990  Michael Tiemann  (tiemann at apple-gunkies.ai.mit.edu)

        * cplus-class.c (compute_conversion_costs): Fixed comments and
        rearranged code that handled type instantiation.  Also handled
        case where type instantiation leaves a parameter ERROR_MARK_NODE
        (consequently making ACTUAL_TYPE ERROR_MARK_NODE).
        * cplus-method.c (report_type_mismatch): Give better error message
        when type instatiation fails and clobbers the argument type.

        * cplus-type2.c (basetype_or_else): Code factorization.
        * All places with code of the form

              if (t1 == t2 || get_base_type (t1, t2, 0))

              else
                do something else;

          now calls this function.

        * cplus-search.c (get_base_type): For jjg@sun.com: let friend
        classes TYPE have access to immediate baseclasses of TYPE.
        * cplus-search.c (get_base_distance): Same change.

        * cplus-method.c (build_opfncall): Give error messages on all
        overloaded functions which non-trivially fail except ADDR_EXPR and
        MODIFY_EXPR.
        * cplus-class.c (build_method_call): Improved error message for
        non-const member function called with const object.

        * cplus-class.c (build_vbase_path): New function.  Multi-level
        version of `build_vbase_pointer'.  Code was moved from
        `convert_to_pointer'.
        * cplus-cvt.c (convert_to_pointer): Call `build_vbase_path'.
        * cplus-cvt.c (convert_pointer_to): Ditto.
        * cplus-cvt.c (convert_to_pointer_force): Remove duplicated code
        and call `build_vbase_path'.

        * cplus-decl.c (original_result_rtx): New variable.  If named
        return value starts in register, but needs to be addressable, then
        we put the original RESULT_DECL's rtl in here.
        * cplus-typeck.c (c_expand_return): Implement this.
        * cplus-decl.c (finish_function): At end of function, if
        ORIGINAL_RESULT_RTX is non-zero, move DECL_RESULT (FNDECL) there.

Fri Jan 12 00:20:06 1990  Michael Tiemann  (tiemann at apple-gunkies.ai.mit.edu)

        * cplus-tree.h (TREE_CALLS_NEW): New meaning for TREE_LANG_FLAG_2:
        for any kind of _EXPR or _REF node, it means that underneath is a
        call to the storage allocator.  If we later find out what was
        wanting initialization, we can pitch the call to `new', and the
        subsequent copy, winning big on things like "return String (foo);".
        * cplus-init.c (build_new): Set this bit.
        * cplus-class.c (build_method_call): Ditto.
        * cplus-method.c (build_opfncall): Ditto.

        constructors.

        * cplus-cvt.c (convert_to_reference): If DECL is ERROR_MARK_NODE,
        then consider this an implicit conversion; if DECL is NULL_TREE,
        it is explicit.
        * cplus-typeck.c (convert_for_initialization): Be explicit that
        this is an implicit conversion.

        * cplus-cvt.c (convert_from_reference): Don't special-case
        converting REFERENCE_EXPRs from references.

        * cplus-cvt.c (convert_to_*): Factor out checks that EXPR is a
        REFERENCE_TYPE object.
        * cplus-cvt.c (convert{_force}): Factor it to here.

        * cplus-cvt.c (convert_pointer_to): New function.  Previously
        `convert_to_nonzero_pointer', but now takes converts to pointer-to
        TYPE, rather than to TYPE.
        * cplus-cvt.c (convert_to_nonzero_pointer): Deleted.
        * All callers changed.

        * cplus-cvt.c (build_up_reference): If LOOKUP_PROTECTED_OK is set,
        let `get_base_type' return an immediate private baseclass without
        complaining.
        * cplus-cvt.c (convert_to_reference): Don't need to check whether
        conversion violates visibilities, since FLAGS is passed to
        `convert_to_reference'.
        * cplus-search.c (get_base_type): Implement that (if PROTECT == 3).

        * stmt.c (*except*): Use ESCAPE_LABEL instead of EXIT_LABEL as
        primary means of control over exception handling nestings.
        Where EXITFLAG was passed, also pass ESCAPEFLAG.
        * All callers changed.  ESCAPEFLAG now controls behavior, not
        EXITFLAG.

        * stmt.c (expand_exit_nonexcept): Delete this function.
        * cplus-parse.y (stmt): Back out change which called
        `expand_exit_nonexcept' instead of `expand_exit_something'.

        * cplus-init.c (expand_recursive_init): Don't forget to initialize
        the vbase pointers if FOR_TYPE uses virtual baseclasses.

        * cplus-class.c (rank_for_overload): const/non-const disagreement
        is between checking EVIL and checking USER.
        * cplus-class.c (build_method_call): Don't hastily choose a method
        which has const/non-const disagreement.

        * cplus-decl.c (build_function_decl): Unify `builtin_function' and
        `auto_function'; also make it optional to push the function into
        the binding contour.
        * cplus-decl.c (init_decl_processing): Build ABORT_FNDECL.
        * cplus-decl2.c (grok_function_init): Use ABORT_FNDECL.
        * cplus-except.c (init_exception_processing): Ditto.

Thu Jan 11 10:39:31 1990  Michael Tiemann  (tiemann at apple-gunkies.ai.mit.edu)

        * cplus-decl2.c (finish_file): Merge changes from Raeburn
        (raeburn@athena.mit.edu) which name file-level initializers
        using global names declared instead of the filename containing
        the objects needing file-level initialization.
        * varasm.c (assemble_{variable,function}): Rest of changes merged.

        * cplus-cvt.c (convert_from_reference): When converting a
        REFERENCE_EXPR, wrap TREE_OPERAND (VAL, 0) in the NOP_EXPR
        instead of VAL--to save work later in `expand_expr'.

        * cplus-tree.h (LOOKUP_NO_CONVERSION): New flag which inhibits
        looking for user-defined type conversions.
        * cplus-type2.c (build_functional_cast): Use LOOKUP_NO_CONVERSION
        when calling constructor since if a type conversion applied, we
        don't want "two-level" conversions to take place.
        * cplus-class.c (build_method_call): Test this flag when PASS == 2
        and cp->user is non-zero.

        * cplus-decl.c (grokdeclarator): Don't set TYPE_HAS_DESTRUCTOR
        here.
        * cplus-decl2.c (grokclassfn): Set it here instead.

Wed Jan 10 07:42:39 1990  Michael Tiemann  (tiemann at apple-gunkies.ai.mit.edu)

        * cplus-class.c (build_method_call): -fall-virtual implies that
        2nd argument to operator->() is an int, not a T (C::*X)(...).

        * cplus-decl.c (finish_function): Keep named return values from
        catching warnings from jump.c about functions which appear to not
        return a value.

        * cplus-type2.c (process_init_constructor): Test INIT before
        copying TREE_HAS_CONSTRUCTOR flag to RESULT.

        * cplus-decl.c (pushdecl): If we had ANON_AGGRNAME_P in "C"
        language scope, and if we get a better name, fix that up as well.
        (Was only doing fixup for "C++" language scope).

        * cplus-method.c (dump_init): Handle CONSTRUCTOR as
        initialization.
        * cplus-typeck.c (actualparameterlist): Here, too.

        * cplus-decl.c (grokdeclarator): Move test of friend functions
        with method qualifiers to `grokfndecl'.
        * cplus-decl.c (grokfndecl): If QUALS is non-zero, then the
        TREE_CODE of TYPE must be METHOD_TYPE.

        * integrate.c (expand_inline_function): Code using
        THIS_STRUCT_VALUE_RTX was (blatantly) incorrect in case where
        STRUCT_VALUE_INCOMING_RTX was MEM.  Code that looked right was
        #if 0'd out, but don't know why.  Changed back to original code.

Tue Jan  9 22:56:22 1990  Michael Tiemann  (tiemann at apple-gunkies.ai.mit.edu)

        * cplus-parse.y (stmt): Exception contour is transparent to BREAK
        statement.  Call `expand_exit_nonexcept' instead of
        `expand_exit_something'.
        * stmt.c (expand_exit_nonexcept): New function.

        * cplus-decl.c (build_enumerator): Accidently shared INTEGER_CST
        nodes which should not have been shared.

Sun Jan  7 00:13:39 1990  Michael Tiemann  (tiemann at g.oswego.edu)

        * cplus-init.c (expand_aggr_init_1): Use CONST0_RTX as TARGET for
        call to `expand_expr' in case of COND_EXPR.
        Similar changes made elsewhere in compiler where `expand_expr' was
        called.

        * cplus-typeck.c (build_modify_expr_1): When CODE is INIT_EXPR,
        and we call a constructor, remember to dereference the result we
        return.

        * cplus-init.c (expand_vec_init): Goto of init_by_default was
        accidently circumventing initialization of variable BASE2.
        Also fixed to handle initialization by default in more cases.

        * cplus-typeck.c (build_modify_expr_1): Typo.  Use "<" instead of
        "<=" for CLASSTYPE_N_BASECLASS loop.
        * cplus-search.c (get_base_type_1): Same typo (but this function
        is never called).

Sat Jan  6 21:55:31 1990  Michael Tiemann  (tiemann at g.oswego.edu)

        * cplus-tree.h (TREE_HAS_CONSTRUCTOR): For CONSTRUCTOR, means that
        it was a GNU C constructor expression.
        * cplus-parse.y (cast_expr): Set that bit.
        * cplus-type2.c (process_init_constructor): Propagate this bit.
        * cplus-init.c (expand_aggr_init_1): Test that bit and call
        `store_init_value' if set.

        * cplus-lex.c: Handle strrchr/rindex problem in one place instead
        of two.

        * cplus-init.c (expand_aggr_init_1): Convert INIT to type for EXP
        treating INIT as compound expr.

        * cplus-decl.c (grokparms): Can't use `error_with_decl' on a
        PARM_DECL here because DECL_CONTEXT is not set up yet.  Fixed in 2
        places.

        * cplus-init.c (resolve_member_ref): Check that member is
        FIELD_DECL before bothering about use of non-static member in
        static function context.

        * cplus-init.c (embrace_waiting_friends): If TYPE_NAME (TYPE) is
        not a TYPE_DECL, it has no friends waiting.

        * cplus-dem.c (optable): Filled in ommissions found by Ron
        Guilmette.

        * cplus-decl2.c (grokopexpr): If IS_DECL tells us we have a static
        member function, but TYPE is a METHOD_TYPE, we must send the right
        argument list to build_operator_fnname.

        * Makefile: Explicitly link all the gen*.o and insn-*.? files.
        Otherwise, we get symbolic links to "gen*.o", etc.

        * make-links.g++: Added symout.c to BORROWED_FILES.

Tue Jan  2 00:39:40 1990    (tiemann at calvin)

        says whether to exit current exception contour and try the next
        one.
        * cplus-parse.y: Callers changed.

        * cplus-decl.c (pushdecl): Clear TREE_PUBLIC only if VAR_DECL is
        TREE_READONLY and not DECL_EXTERNAL.  DECL_EXTERNAL is meaningless
        for other than VAR_DECLs.
        * cplus-decl.c (duplicate_decls): Same change.
        @@ Maybe we can eliminate some duplicated code here!

        * cplus-tree.c (copy_to_permanent): If T is NULL_TREE, return it.

        * cplus-cvt.c (convert_to_aggr): Deal with "in charge" parameter
        if BASETYPE uses virtual baseclasses.

        * cplus-class.c (build_overload_call): Change name of DECL to
        OVERLOAD_NAME.  Also, append VOID_LIST_NODE to end of PARMTYPES,
        to build more accurate overload name.

        * cplus-decl.c (store_parm_decls): No need for PRESERVE flag, so
        deleted.  All callers changed.

        * cplus-parse.y (member_init): De-implement keeping virtual
        baseclass initializers on the permanent obstack.  Now handled by
        "in charge" parameter to constructor.

        * cplus-cvt.c (convert_to_reference): Convert EXPR from reference
        if it came in as a reference and its conversion to TYPE& may
        change its value (i.e., if it uses MI or VB).

        * cplus-class.c (build_method_call): Use DECL_CONTEXT, not
        DECL_VCONTEXT of FUNCTION when LOOKUP_NONVIRTUAL is in effect.
        Factored out duplicated code in the process.

        * cplus-class.c (build_method_call): Constructors called when
        `this' is logically zero must perform any virtual baseclass
        initialization.  Other constructors (which are used for
        initialization of sub-ojbects), never perform virtual baseclass
        initialization.
