3220 modify_all_vtables): New routines.
3221 * class.c (finish_struct): Added arguemnt to prepare_fresh_vtable
3222 call. General cleanup on how pending_hard_virtuals are handled.
3223 General cleanup on modifying vtables. Use finish_vtbls, instead of
3224 unmark_finished_struct.
3225 * cp-tree.h (init_vtbl_ptrs, expand_direct_vtbls_init,
3226 get_first_matching_virtual, get_matching_virtual,

3234 * init.c (init_vtbl_ptrs): Rename to expand_direct_vtbls_init, added
3235 two arguments to make more general. Made more general. Now can be
3236 used for vtable pointer initialization from virtual bases.
3237 * init.c (emit_base_init): Change expand_vbase_vtables_init call to
3238 expand_indirect_vtbls_init. Change init_vtbl_ptrs call to
3239 expand_direct_vtbls_init.
3240 * init.c (expand_virtual_init): General cleanup.
3241 * init.c (expand_default_init): Change expand_vbase_vtables_init
3242 call to expand_indirect_vtbls_init.

3249 DECL_CONTEXT. That is now done in a cleaner way in
3250 modify_vtable_entry and add_virtual_function.
3251 * search.c (expand_vbase_vtables_init): Rename to
3252 expand_indirect_vtbls_init. General cleanup. Use
3253 expand_direct_vtbls_init to do hard work. Ensures that _all_ vtable
3254 pointers from virtual bases are set up.
3255 * search.c (bfs_unmark_finished_struct, unmark_finished_struct):
3258 * *.[chy]: Remove support for VTABLE_USES_MASK.
3260 Tue Apr 19 12:51:59 1994 Jason Merrill <jason@deneb.cygnus.com>
3262 * cvt.c (convert_to_reference): Use NOP_EXPRs to switch between
3263 reference and pointer types instead of bashing the types directly.
3265 * call.c (build_overload_call_real): Use the TREE_CODE to determine
3266 whether the function is overloaded or not, rather than
3268 * *: Remove all uses of TREE_OVERLOADED.
3270 * decl.c (grokdeclarator): Only complain about initializing const
3271 fields when -ansi or -pedantic.

3281 (struct binding_level): Add overloads_shadowed field.
3282 (poplevel): Restore overloads_shadowed.

3312 before we get to left_curly.
3313 * pt.c (instantiate_class_template): Set TYPE_BEING_DEFINED.
3315 * error.c (dump_decl): If it's a typedef, print out the name of the
3316 decl, not just the underlying type.
3318 * decl.c (pushdecl): If the old duplicate decl was a TYPE_DECL,
3319 update the IDENTIFIER_TYPE_VALUE of its name.
3321 * decl2.c (finish_file): When processing the initializer for a
3322 static member, pretend that the dummy function is a member of the

3333 * typeck.c (build_conditional_expr): Pedwarn on pointer/integer
3334 mismatch, and don't pedwarn on 0/function pointer mismatch.
3336 * typeck2.c (digest_init): Lose code for special handling of unions.
3337 (process_init_constructor): Since they're handled just fine here.
3338 Pedwarn on excess elements.
3340 * decl2.c (grokfield): Complain about local class method declaration
3343 Fri Apr 15 13:19:40 1994 Per Bothner <bothner@kalessin.cygnus.com>
3345 * method.c (emit_thunk): Add extern declaration for
3346 current_call_is_indirect (needed for hppa).
3348 Thu Apr 14 16:12:31 1994 Jason Merrill <jason@deneb.cygnus.com>
3350 Improve local class support; allow classes in different blocks to
3352 * decl.c (pushtag): Support local classes better.
3353 (pushdecl_nonclass_level): New function for pushing mangled decls of
3354 nested types into the appropriate scope.
3355 (xref_defn_tag): Use pushdecl_nonclass_level instead of
3357 (grokfndecl): Don't mess with IDENTIFIER_GLOBAL_VALUE for local
3359 * method.c (do_inline_function_hair): Likewise.
3361 * class.c (finish_struct): It is legal for a class with no
3362 constructors to have nonstatic const and reference members.
3364 Thu Apr 14 07:15:11 1994 Brendan Kehoe <brendan@lisa.cygnus.com>
3366 * decl.c (push_overloaded_decl): Avoid giving errors about
3367 built-ins, since duplicate_decls will have given warnings/errors
3370 Thu Apr 14 03:45:12 1994 Jason Merrill <jason@deneb.cygnus.com>
3372 * cvt.c (convert_to_reference): Warn about casting pointer type to
3373 reference type when this is probably not what they wanted.
3375 Wed Apr 13 13:12:35 1994 Per Bothner <bothner@kalessin.cygnus.com>
3377 * decl.c (finish_decl): Don't mindlessly set TREE_USED for
3378 static consts any more (toplev.c has now been modified to
3379 not emit warnings if they are unused).
3381 Wed Apr 13 00:22:35 1994 Jason Merrill <jason@deneb.cygnus.com>
3383 * decl.c (grok_op_properties): If op new/delete get here with
3384 METHOD_TYPEs, do a revert_static_member_fn.
3386 * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
3387 * init.c (is_aggr_typedef): Don't look at
3388 IDENTIFIER_CLASS_TYPE_VALUE.
3389 (get_aggr_from_typedef): Likewise.
3390 (get_type_value): Likewise.
3391 * call.c (build_scoped_method_call): Don't rely on overloaded
3392 template names having IDENTIFIER_CLASS_VALUE set.
3394 * parse.y (component_decl_1, fn.def2): Revert rules for
3396 (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
3399 * decl.c (start_function): Only warn about `void main()' if pedantic
3400 || warn_return_type.
3402 Tue Apr 12 02:14:17 1994 Jason Merrill <jason@deneb.cygnus.com>
3404 Clean up overloading of the template name.
3405 * class.c (pushclass): Overload the template name whenever pushing
3406 into the scope of a template class, not just if it is
3408 (popclass): Correspondingly.
3409 * search.c (push_class_decls): Don't overload_template_name.
3410 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
3411 DECL_CONTEXT on things.
3412 * parse.y (left_curly): Don't overload_template_name.
3413 * class.c (finish_struct): Don't undo_template_name_overload.
3415 * method.c (build_opfncall): Only pass one argument to global op
3418 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
3419 decide how many arguments to use for vec delete.
3421 * decl.c (grok_op_properties): Be consistent in modifying
3423 (grokdeclarator): Only complain about function decls with no return
3424 type if we're being pedantic.
3426 Mon Apr 11 00:10:53 1994 Jason Merrill <jason@deneb.cygnus.com>
3428 Add support for operator new [] and operator delete [].

3431 * ptree.c (print_lang_type): Indicate vec new/delete.
3432 * parse.y: Support vec new/delete.
3433 * method.c (build_decl_overload): Deal with vec new/delete.
3434 (build_opfncall): Likewise.
3435 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
3436 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
3437 * init.c (init_init_processing): Set up BIVN and BIVD.
3438 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
3439 since it doesn't happen any more.
3440 (build_new): Support vec new. Always call something.
3441 (build_x_delete): Support vec delete.
3442 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
3443 and pass it to build_x_delete.
3444 * decl2.c (delete_sanity): Don't change behavior by whether or not
3445 the type has a destructor. Pass use_global_delete to
3447 (coerce_delete_type): Make sure that the type returned has a first
3448 argument of ptr_type_node.
3449 * decl.c (init_decl_processing): Also declare the global vec
3451 (grokdeclarator): Also force vec new/delete to be static.
3452 (grok_op_properties): Note presence of vec new/delete, and play with
3453 their args. If vec delete takes the optional size_t argument, set
3454 TYPE_VEC_DELETE_TAKES_SIZE.
3455 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
3456 checking for one delete or the other.
3457 (lang_type): gets_new and gets_delete are now two bits long. The
3458 low bit is for the non-array version. Lose gets_placed_new.
3459 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
3460 delete defined by this class wants to know how much space it is
3462 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
3463 add a header containing the number of elements in the vector; i.e.
3464 when the elements need to be destroyed or vec delete wants to know
3466 * class.c (finish_struct_methods): Also check for overloading vec
3468 * call.c (build_method_call): Also delete second argument for vec
3471 * decl.c (grokdeclarator): Correct complaints again.
3472 (grokdeclarator): Fix segfault on null declarator.
3473 (decls_match): Also accept redeclaration with no arguments if both
3474 declarations were in C context. Bash TREE_TYPE (newdecl) here.
3475 (duplicate_decls): Instead of here.
3477 * parse.y (nested_name_specifier_1): Lose rules for dealing with
3478 syntax errors nicely, since they break parsing of 'const i;'.
3480 * decl.c (lookup_name): if (got_scope == current_class_type)
3481 val = IDENTIFIER_CLASS_VALUE (name).
3483 * search.c (lookup_nested_tag): Look in enclosing classes, too.
3485 * spew.c (yylex): Only look one character ahead when checking for a
3488 * lex.c (check_newline): Read first nonwhite char before
3489 incrementing lineno.
3491 * decl.c (grokdeclarator): Don't claim that typedefs are variables
3494 * parse.y: Divide up uses of unqualified_id into
3495 notype_unqualified_id and unqualified_id, so that TYPENAME can be
3496 used as an identifier after an object.
3498 * class.c (push_nested_class): Don't push into non-class scope.
3500 * decl.c (grokdeclarator): If an identifier could be a type
3501 conversion operator, but has no associated type, it's not a type
3502 conversion operator.
3504 * pt.c (unify): Check for equality of constants better.
3506 * decl.c (grokdeclarator): Don't complain about access decls.
3508 Sun Apr 10 02:39:55 1994 Jason Merrill <jason@deneb.cygnus.com>
3510 * decl.c (grokdeclarator): pedwarn about data definitions without
3513 * parse.y (datadef): Don't pedwarn about decls without types here,
3514 since that is valid for functions.
3515 (fn.def2, component_decl): Support constructors with declmods again.
3516 (nomods_initdecls): For decls without any mods, so that we don't try
3517 to get declspecs from some arbitrary $0.
3519 * search.c (lookup_field): Use cp_error.
3521 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
3522 here; it breaks destructors for non-aggr types.
3524 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
3525 a type being defined, like the comment says.
3526 If got_scope is not an aggregate, just return NULL_TREE.
3528 * pt.c (create_nested_upt): Kung's code for creating types nested
3529 within uninstantiated templates now lives here (it used to live in
3530 hack_more_ids). It needs to be expanded.
3532 * parse.y: Stop calling see_typename so much.
3534 * decl.c (lookup_name): Deal with TTPs and UPTs.
3536 * lex.c (real_yylex): Don't set looking_for_typename just because we
3538 (dont_see_typename): #if 0 out.
3540 * spew.c (yylex): Increment looking_for_typename if the next
3541 character is SCOPE, rather than setting it to 1; this way, the value
3542 from seeing an aggr specifier will not be lost. This kinda relies
3543 on looking_for_typename never being < 0, which is now true.
3545 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
3547 (named_class_head_sans_basetype): Accept template types, too. Oops.
3549 Fri Apr 8 16:39:35 1994 Jason Merrill <jason@deneb.cygnus.com>
3551 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
3553 * parse.y: Lose START_DECLARATOR.
3555 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
3558 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
3559 A::foo' syntax. Catch invalid scopes better.
3561 * parse.y, lex.c: Lose TYPENAME_COLON.
3563 * decl2.c (groktypefield): #if 0 out.
3565 * decl.c (lookup_name): If the type denoted by got_scope is
3566 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
3568 * class.c (push_nested_class): Don't try to push into
3571 Fri Apr 8 07:26:36 1994 Brendan Kehoe <brendan@lisa.cygnus.com>
3573 * Makefile.in (stamp-parse): Update count of conflicts to 33.
3575 Thu Apr 7 17:47:53 1994 Jason Merrill <jason@deneb.cygnus.com>
3577 A saner implementation of nested types that treats template types
3578 no differently from non-template types. There are still some
3579 shortcomings of our system; most notably, it is difficult to look
3580 for a nested type that is hidden by another name, because of the way
3581 we keep track of hidden types. But this shouldn't be a problem for
3582 just about anyone. Perhaps lookup_field should be fixed up a bit.
3584 * spew.c: Moved handling of nested types/scoping from the lexer
3585 into the parser. Removed variable template_type_seen_before_scope.
3586 Removed functions frob_identifier, hack_more_ids, and various cruft
3587 that was #if 0'd out in the past, reducing the size of the file from
3588 1146 lines to 450 lines. We can't quite do away with spew.c yet,
3589 though; we still need it for do_aggr () and checking for SCOPE after
3590 the current identifier. And setting lastiddecl.
3592 * parse.y: Moved handling of nested types/scoping from the lexer
3593 into the parser, using a new global variable `got_scope'. Reduced
3594 the number of states by 53. Implemented all uses of explicit global
3595 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
3596 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
3597 scoped_typename. Added nonterminals nested_type,
3598 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
3599 nested_name_specifier, global_scope, overqualified_id, type_name.
3600 Changed many others. Added 9 new reduce/reduce conflicts, which are
3601 nested type parallels of 9 that were already in the grammar for
3602 non-nested types. Eight of the now 33 conflicts should be removed
3603 in the process of resolving the late binding between variable and
3606 * gxxint.texi (Parser): Update.
3608 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
3610 * lex.h: Add decl for got_scope.
3612 * lex.c (see_typename): Claim to be the lexer when calling
3615 * decl.c (lookup_name): When called from the lexer, look at
3616 got_scope and looking_at_typename; otherwise don't.
3618 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
3620 31th Cygnus<->FSF merge.
3622 Thu Apr 7 17:47:53 1994 Jason Merrill <jason@deneb.cygnus.com>
3624 * decl2.c (mark_vtable_entries): Call this to mark all the
3625 entries in the vtable addressable.

3640 Wed Apr 6 16:05:10 1994 Per Bothner <bothner@kalessin.cygnus.com>
3642 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
3643 ch-tree.h: Every place these functions were called, the result was
3644 immediately passed to expand_expr_stmt. Reduce redundancy by
3645 calling expand_expr_init *inside* these functions. These
3646 makes for a simpler interface, and we don't have to build
3647 compound expressions. Hence, rename these function to:
3648 expand_virtual_init and expand_vbase_vtables_init respectively.
3649 * init.c, decl.c: Change callers of these functions.
3650 * init.c, cp-tree.h (expand_virtual_init): Make static.
3652 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE

3657 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
3659 * decl.c (duplicate_decls): If this is a new declaration of an
3660 extern "C" function, keep the type (for the argtypes).
3661 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
3662 (decls_match): Call compparms with a value of strict dependent on
3663 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
3665 * typeck.c (compparms): ... is only equivalent to non-promoting
3666 parms if we're not being strict.
3668 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
3670 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
3671 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
3673 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

3683 * class.c (build_vtable_entry): Build thunk if necessary.
3684 * class.c (build_vfn_ref): If using thunks, don't need
3685 to add delta field from vtable (there is none!).
3686 * decl.c: Add memptr_type as well as vtable_entry_type.
3687 If using thunks, the latter is just ptr_type_node.
3688 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
3689 * decl2.c (finish_vtable_vardecl): Handle thunks.
3690 * expr.c (cplus_expand_expr): Support THUNK_DECL.
3692 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
3693 * decl.c (start_function): Set current_extern_inline based on
3694 DECL_THIS_EXTERN, not TREE_PUBLIC.
3695 * decl.c (finish_function): Call mark_inline_for_output if needed,
3697 Improve intelligence about when to emit inlines.
3698 * cp-tree.h (lang_decl_flags): New field saved_inline.
3699 * cp-tree.h (DECL_SAVED_INLINE): New macro.
3700 * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.
3701 * decl.h, decl.c (pending_addressable_inlines): Removed.
3702 * decl2.c (pending_addressable_inlines): Renamed to saved_inlines.
3703 * decl2.c (mark_inline_for_output): Do nothing if
3704 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
3705 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
3706 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.

3714 compatibility, but should become the default in a future release.)

3718 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT

3729 * typeck.c (c_expand_return): Before checking that we're not
3730 returning the address of a local, make sure it's a VAR_DECL.

3735 * parse.y (YYDEBUG): Always define.

3883 * decl.c (start_method): Methods defined in the class body are
3884 inline whether or not it's a template class.

3911 * typeck.c (comp_target_types): Call comp_target_parms with

4056 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
4057 in FIELD context, when appropriate. Also,
4058 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.

4061 Mon Mar 21 11:46:55 1994 Jason Merrill <jason@deneb.cygnus.com>
4063 * parse.y (after_type_declarator1): Expand type_quals.

4075 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.

4100 (named_parm): Add typespec direct_declarator rule.
4102 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
4104 These two patches disable some excessive cleverness on the part of
4105 g++; a non-class declaration always hides a class declaration in the
4106 same scope, and g++ was trying to unhide it depending on the
4107 enclosing expression.
4109 * spew.c (arbitrate_lookup): #if 0 out.
4111 * decl.c (lookup_name): Never call arbitrate_lookup.
4113 * parse.y (complex_notype_declarator1): Add '*'

4123 These changes fix the compiler's handling of the functional cast/
4124 object declaration ambiguities in section 6.8 of the ARM. They also

4128 (notype_unqualified_id): New nonterminal, encompasses all of the
4129 ANSI unqualified-id nonterminal except TYPENAMEs.
4130 (expr_or_declarator): New nonterminal to delay parsing of code like

4137 an expr_or_declarator.
4138 (complex_direct_notype_declarator): A direct_notype_declarator that
4139 doesn't conflict with expr_or_declarator. Use
4140 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
4141 (functional_cast): New nonterminal, for the three functional cast
4142 rules. So that they can be moved after
4143 complex_direct_notype_declarator.
4144 (see_typename): Don't accept type_quals any more.
4146 * decl2.c (reparse_decl_as_expr): New function to deal with parse
4147 nodes for code like `int (*a)++;'.
4148 (reparse_decl_as_expr1): Recursive subroutine of the above.
4149 (finish_decl_parsing): New function to deal with parse nodes for
4150 code like `int (*a);'. See the difference?
4152 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
4154 These changes break binary compatibility in code with classes
4155 that use virtual bases.

4158 sure virtual bases are initialized in dfs ordering.
4159 * search.c (get_vbase_types): Simplify and make readable.
4161 Thu Mar 17 12:01:10 1994 Jason Merrill <jason@deneb.cygnus.com>

4176 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
4177 all of the scoped PTYPENAME rules.
4179 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
4181 * init.c (build_offset_ref): The value of A::typedef_name is
4182 always the TYPE_DECL, and never an error.
4184 Tue Mar 15 20:02:35 1994 Jason Merrill <jason@deneb.cygnus.com>
4186 * search.c (get_base_distance_recursive): Two binfos can only
4187 represent the same object if they are both via_virtual.
4189 * class.c (finish_base_struct): Check vbases for ambiguity, too.
4191 * search.c (get_vbase_types): Accept binfo argument, too.
4193 Tue Mar 15 19:22:05 1994 Kung Hsu <kung@mexican.cygnus.com>
4195 * decl.c (complete_array_type): Complete TYPE_DOMAIN of the
4196 initializer also, because back-end requires it.
4198 Tue Mar 15 15:33:31 1994 Jason Merrill <jason@deneb.cygnus.com>
4200 * error.c (dump_expr): Support member functions (which show up as

4231 (direct_abstract_declarator): Replace '(' parmlist ')' rule with
4232 '(' complex_parmlist ')' and regcast_or_absdcl.
4234 (complex_parmlist): Parmlists that are not also typenames.
4235 (parms_comma): Enabler.
4236 (named_parm): A parm that is not also a typename. Use declarator
4237 rather than dont_see_typename abs_or_notype_decl. Expand

4245 * decl2.c (reparse_decl_as_casts): New function to change parse
4246 nodes for `(int)(int)(int)' from "function taking int and returning
4247 function taking int and returning function taking int" to "... cast
4248 to int, cast to int, cast to int".
4250 * decl2.c (reparse_decl_as_expr): Recursive function to change
4251 parse nodes for `A()()' from "function returning function returning
4252 A" to "A().operator()".

4255 `typespec fcast_or_absdcl' rule.

4265 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
4266 matches Section 5.5.
4268 Fri Mar 4 14:01:59 1994 Jason Merrill <jason@deneb.cygnus.com>
4270 * error.c (dump_type_prefix): Don't print basetype twice for

4275 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
4276 so that it is like setHandler(&A::handlerFn). Cures an `invalid

4281 * gxxint.texi (Copying Objects): New section discussing default
4282 op= problems with virtual inheritance.
4284 * decl2.c (grokoptypename): Just does grokdeclarator and
4285 build_typename_overload, since the parser can't call grokdeclarator
4288 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
4289 and TREE_TYPE on generated identifiers.
4291 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.

4296 if we can't figure out what to do.
4297 (dump_type*): Likewise.
4299 * typeck2.c (build_m_component_ref): 'component' is an expr, not
4300 a decl. Also move the IS_AGGR_TYPE check after the stripping of
4303 Fri Mar 4 04:46:05 1994 Mike Stump <mrs@cygnus.com>
4305 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
4306 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid
4307 lvalue in unary `&''.

4311 * parse.y: Add precedence specification for START_DECLARATOR.

4317 * decl.c (grokdeclarator): Parse TYPE_EXPRs in the initial scan,
4318 rather than waiting until later.
4320 Wed Mar 2 14:12:23 1994 Jason Merrill <jason@deneb.cygnus.com>
4322 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather

4324 (typename): Expand empty option of (former) absdcl inline.
4325 (abs_or_notype_decl): Likewise.
4326 (absdcl): Lose empty rule.
4327 (conversion_declarator): New nonterminal for 'typename' of 'operator

4334 directly. Add rules with reserved_typespecquals.
4335 (reserved_declspecs): Don't accept typespecqual_reserved at the
4336 beginning of the list. The typed_declspecs rule will deal with this
4338 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
4341 * parse.y (direct_notype_declarator,
4342 direct_after_type_declarator, direct_abstract_declarator): Split up
4343 the declarator1 nonterminals to match the draft standard and avoid

4357 * tree.c (get_identifier_list): New function, containing code
4358 previously duplicated in get_decl_list and list_hash_lookup_or_cons.
4359 (get_decl_list): Use it.
4360 (list_hash_lookup_or_cons): Likewise.
4362 * parse.y (typed_declspecs, declmods): It's not necessary to hash
4363 the declspecs on class_obstack, so don't. This way typed_typespecs
4364 can reduce to typed_declspecs.
4366 Wed Mar 2 14:29:18 1994 Jason Merrill <jason@cygnus.com>
4368 * cvt.c (build_up_reference): If we aren't checking visibility,
4369 also allow base->derived conversions.

4373 * typeck.c (build_c_cast): Remove bogus hack when converting

4385 a non-inline virtual function to control emitting of vtables.
4386 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
4387 * search.c (build_vbase_vtables_init): Don't assemble_external
4388 (yet) if flag_vtable_hack.

4391 Mon Feb 28 14:54:13 1994 Jason Merrill <jason@deneb.cygnus.com>
4393 * parse.y (component_decl): Don't include "typed_declspecs
4394 declarator ';'" speedup, since it breaks enums.

4405 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
4407 * lex.c (check_newline): #pragma interface can take a string
4408 argument, just like #pragma implementation. #pragma implementation
4409 checks for garbage on the line, line #pragma interface does. Main
4410 input files do not auto implement like named files, #pragma
4411 implementation must be used explicitly.
4413 Thu Feb 24 17:09:01 1994 Jason Merrill <jason@deneb.cygnus.com>
4415 * parse.y (components): Handle list of one again.

4425 * Makefile.in (stamp-parse): Update expected conflict count.
4427 * parse.y (various): Replace "declmods declarator" with "declmods
4428 notype_declarator". The comment saying that "declmods declarator ';'"
4429 corresponds to "int i;" was wrong; it corresponds to "const i;".
4430 (component_decl): Add "typed_declspecs declarator ';'" rule; this
4431 *does* correspond to "int i;". Change "declmods components" to
4432 "declmods notype_components".
4433 (components): Don't deal with a list of one anymore.
4434 (notype_components): New nonterminal, corresponds to notype_declarator.

4446 nonterminal so that we can stick %prec EMPTY on it.
4448 Add more %prec EMPTY's to eliminate remaining shift/reduce
4451 (after_type_declarator): Add maybe_raises to fndecl rules.
4452 (after_type_declarator_no_typename): Remove.
4455 Document remaining reduce/reduce conflicts.

4459 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
4460 (TYPE_BINFO (type)) if we care about the path.
4462 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
4465 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>

4472 * parse.y: Eliminate 20 shift/reduce conflicts.
4474 Fri Feb 18 11:49:42 1994 Jason Merrill <jason@deneb.cygnus.com>
4476 * pt.c (type_unification): Add subr argument; if set, it means
4477 that we are calling ourselves recursively, so a partial match is OK.
4478 (unify): Support pointers to methods and functions.
4479 (tsubst): Support method pointers.
4480 * decl.c (build_ptrmemfunc_type): No longer static, so that

4485 * decl2.c (build_push_scope): If cname refers to a template type
4486 parm, just grin and nod.

4490 * pt.c (do_function_instantiation): Likewise.
4491 * class.c (instantiate_type): Likewise.
4493 * search.c (get_base_distance): If BINFO is a binfo, use it and
4494 don't mess with its BINFO_INHERITANCE_CHAIN.
4496 * cvt.c (convert_to_reference): Fix temporary generation.
4497 If ambiguous, return error_mark_node.
4499 * init.c (build_new): Put back some necessary code.

4518 Thu Feb 17 15:12:29 1994 Per Bothner <bothner@kalessin.cygnus.com>
4520 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,
4521 rather than integer_type_node. Does wonders for the Alpha.

4525 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
4526 goes onto the same obstack as its target type.
4528 Wed Feb 16 00:34:46 1994 Jason Merrill <jason@deneb.cygnus.com>
4530 * cvt.c (convert_to_reference): If converting via constructor
4531 on local level, go back to build_cplus_new approach.
4533 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
4534 to error_mark_node to prevent expand_expr from building a cleanup
4537 * lex.c (default_assign_ref_body): Return *this from the memcpy
4540 * decl.c (grok_reference_init): Just return if called with
4541 error_mark_node, don't worry about initializing non-const reference
4544 * cvt.c (convert_to_reference): Do the right thing for
4545 non-aggregate reference conversions, pedwarn when generating a
4546 non-const reference to a temporary.
4548 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
4549 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
4552 Tue Feb 15 19:47:19 1994 Jason Merrill <jason@deneb.cygnus.com>
4554 * decl.c (grok_reference_init): Pawn off a lot of the work on
4555 convert_to_reference. Generally do the right thing.
4557 * cvt.c (convert_to_reference): Conform to the initial comment;
4558 i.e. don't create temps if decl != error_mark_node. Handle
4559 cleanups better for temps that do get created. Don't pretend
4560 that we can use an 'A' to initialize a 'const double &' just by
4561 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
4563 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

4574 * decl.c (pushdecl): Define decl in correct binding_level
4575 (which isn't always the inner_binding_level).
4577 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
4578 It's ugly, and I don't think it's the right thing to do.
4580 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
4581 Remove NEW_CLASS_SCOPING, assuming it is always 1.
4582 * decl.c (pop_decl_level): Removed; manually inlined.
4584 Sun Feb 13 19:04:56 1994 Jason Merrill <jason@deneb.cygnus.com>

4604 with destructor names when either NO_DOLLAR_IN_LABEL or

4609 * pt.c (grok_template_type): Substitute template parm types
4610 with actual types in complex type as well.
4611 (coerce_template_parms): Update the grok_template_type ()
4614 * pt.c (tsubst): Traverse method list using DECL_CHAIN.
4616 * decl.c (grok_op_properties): Allow operator++/-- to have
4619 * typeck2.c (store_init_value): Don't abort when called to
4620 initialize a type that needs constructing with a CONSTRUCTOR.
4622 * init.c (expand_aggr_init_1, CONSTRUCTOR case): If
4623 store_init_value fails, build and expand an INIT_EXPR. If

4628 * class.c (build_vbase_path): Use complete_type_p instead of
4629 resolves_to_fixed_type_p to determine if the virtual bases are in
4630 their right place for the type of expr. Cures problem of thinking a
4631 virtual base class is one place, when it is in fact someplace else.
4633 Fri Feb 11 00:26:46 1994 Mike Stump <mrs@cygnus.com>
4635 * init.c (resolve_offset_ref): Make sure we first convert to
4636 intermediate type, if given, when dealing with members off `this'.
4637 Solves an incorrrect `type `foo' is not a base type for type
4638 `multiple'' when it is infact, a base type.
4640 Thu Feb 10 21:49:35 1994 Mike Stump <mrs@cygnus.com>
4642 * class.c (modify_other_vtable_entries): Use get_binfo, instead
4643 of binfo_value. Solves problem with compiler giving a `base class
4644 `B' ambiguous in binfo_value (compiler error)' on complex MI
4645 herarchies, when a virtual function is first defied in a virtual

4685 delete, make static virtuals unvirtual instead of unstatic.

4690 * decl.c (grokdeclarator): Don't complain about anonymous
4693 * parse.y (simple_stmt, for loops): Move the continue point after

4697 TYPE_HAS_COMPLEX_INIT_REF.
4699 Tue Feb 8 13:21:40 1994 Jason Merrill <jason@deneb.cygnus.com>

4703 * class.c (finish_struct): TYPE_HAS_COMPLEX_*_REF are supersets of
4704 TYPE_HAS_REAL_*_REF, but TYPE_HAS_COMPLEX_INIT_REF is independent of
4705 TYPE_NEEDS_CONSTRUCTING.
4707 * decl.c (duplicate_decls): Propagate access decls.
4709 * typeck2.c (process_init_constructor): Accept empty_init_node
4710 for initializing unions.
4712 * class.c, lex.c, cp-tree.h: Use
4713 TYPE_HAS_COMPLEX_ASSIGN_REF where TYPE_HAS_REAL_ASSIGN_REF was used
4714 before, use TYPE_HAS_COMPLEX_INIT_REF for TYPE_NEEDS_CONSTRUCTING in
4717 * decl.c (finish_decl): Don't complain about uninitialized const
4718 if it was initialized before.
4720 Mon Feb 7 18:12:34 1994 Jason Merrill <jason@deneb.cygnus.com>
