2574 handlers of a function-try-block.
2576 (component_decl): Make sure TRY and RETURN can come after fn.def2.
2577 * spew.c (peekyylex): New routine to peek at what will come next.

2596 * parse.y (fndef): Enhance readability and maintainability. Update
2597 to include function_try_block syntax.
2598 (function_try_block): Add.

2676 Wed Aug 30 15:24:38 1995 Stephen L. Favor (sfavor@tigger.intecom.com)
2678 * except.c (expand_builtin_throw): Moved gen_label_rtx calls beyond
2679 the store_parm_decls call which does initialization in the emit_*
2680 code concerning label numbering.
2682 Thu Aug 31 09:01:07 1995 Mike Stump <mrs@cygnus.com>
2684 * except.c (expand_internal_throw): Let the frontend be responsible
2685 for managing all frontend EH parameters, the backend routine only
2686 needs to deal with backend values. type and value are no longer
2688 (init_exception_processing): Ditto.

2705 value are now trees.
2707 Mon Aug 28 17:57:45 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2709 Fix the attribute handling to make sure they get noted before we
2710 create the function's RTL, in case they can affect that.
2711 * decl.c (grokfndecl): New arg ATTRLIST. Run
2712 cplus_decl_attributes before creating the decl's rtl.

2732 * except.c: Always allow turning on exception handling. Allow cross

2759 Tue Aug 22 17:20:07 1995 Per Bothner <bothner@kalessin.cygnus.com>
2761 * decl2.c (flag_new_for_scope): Add a new mode that follows ANSI
2762 for-scoping, but supports (and warns about) old programs.
2763 Make the new mode (with value 1) the default.
2764 (lang_f_options): The on-value for flag_new_for_scope is now 2.
2765 * cp-tree.h (DECL_DEAD_FOR_LOCAL, DECL_ERROR_REPORTED): New macros
2766 (DECL_SHADOWED_FOR_VAR): Likewise.
2767 * decl.c (struct binding_level): New fields dead_vars_from_for

2776 Mon Aug 21 10:28:31 1995 Jason Merrill <jason@deneb.cygnus.com>
2778 * decl2.c (import_export_inline): Class interface hackery does not

2783 * search.c (virtual_context): Find the right context more often.
2784 Solves a `recoverable compiler error, fixups for virtual function'
2787 Sun Aug 20 13:53:24 1995 Mike Stump <mrs@cygnus.com>
2789 * except.c (expand_start_all_catch): Ensure that we always transfer
2790 control to the right EH handler, by rethrowing the end label on the
2791 region, instead of hoping we are nested and falling through.
2792 (expand_leftover_cleanups): Ditto.
2793 (end_protect): Since we now rethrow the end label, put a
2794 nop after it, so that outer regions are recognized.
2795 * init.c (build_vec_delete_1): New routine to handle most of vector
2796 deleting, all code moved here from build_vec_delete.
2797 (build_array_eh_cleanup): Use build_vec_delete_1 to do all the real

2800 EH region to handle it.

2802 build_vec_delete_1 to do the grunt work.
2804 Sat Aug 19 14:25:33 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2806 Handle decl attributes properly for function definitions without
2807 previous attribute-loaded declarations.
2808 * decl.c (start_function): New arg ATTRS. Add a call to
2809 cplus_decl_attributes with it before we create the RTL.
2810 * cp-tree.h (start_function): Update prototype.
2811 * parse.y (fn.def1): Pass ATTRS into start_function instead of

2814 * decl2.c (finish_file): Pass NULL_TREE as fourth arg to
2816 * method.c (synthesize_method): Likewise.
2817 * except.c (expand_builtin_throw): Likewise for start on __throw.
2819 Sat Aug 19 13:36:08 1995 Mike Stump <mrs@cygnus.com>
2821 * class.c (set_rtti_entry): Turn on -fvtable-thunk -frtti support.
2822 This changes -fvtable-thunks vtable layout, so a recompile will be
2823 necessary, if you use -fvtable-thunks.
2824 (get_vtable_entry): Use n, instead of i to be consistent with the
2825 rest of the compiler.
2826 (get_vtable_entry_n): Ditto.

2841 * cp-tree.h (skip_rtti_stuff): New routine, declare it.
2842 * gc.c (build_headof): Support -fvtable-thunk and -frtti together.

2852 * decl.c (start_function): Clear ctor_label and dtor_label.

2859 can be used for class template definitions, as well.
2860 (finish_struct_1): New function with the rest of the code.
2862 Tue Aug 15 09:46:16 1995 Mike Stump <mrs@cygnus.com>
2864 * class.c (prepare_fresh_vtable): On second though, always build the
2865 offset (see Aug 10 change), unless -fvtable-thunks is given. It
2866 does this by calling the new routine set_rtti_entry.
2867 (finish_struct): Ditto.
2868 (set_rtti_entry): New routine to update the rtti information at the
2869 start of the vtable.
2871 Mon Aug 14 12:21:22 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2873 * error.c (dump_decl, case IDENTIFIER_NODE): Only work on a dtor
2874 if it's declared in the C++ language spec.
2875 (dump_function_decl): Likewise.
2876 (dump_function_name): Likewise.
2877 (ident_fndecl): Make sure we got something back from lookup_name.
2878 * decl.c (start_function): Likewise.
2880 Fri Aug 11 16:52:15 1995 Jason Merrill <jason@phydeaux.cygnus.com>
2882 * call.c (build_method_call): Don't call build_new when calling a
2883 constructor without an instance.
2885 Thu Aug 10 20:00:17 1995 Mike Stump <mrs@cygnus.com>
2887 * class.c (prepare_fresh_vtable): Always build the offset to the
2888 complete object, as it doesn't cost much. This allows dynamic_cast
2889 to void * to work when -frtti isn't given.
2890 (finish_struct): Ditto.
2892 Thu Aug 10 16:31:28 1995 Mike Stump <mrs@cygnus.com>
2894 * except.c (build_eh_type): Split out some functionality to new
2895 routine named build_eh_type_type.
2896 (build_eh_type_type): New routine.
2897 (expand_start_catch_block): Use build_eh_type_type, as we never want
2898 the dynamic type of the catch parameter, just the static type.
2899 Fixes core dumps when -frtti is used and one catchs pointers to
2902 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
2904 * except.c (expand_builtin_throw): Since we now use normal calling
2905 conventions for __throw, we have to remove the first layer off the
2906 stack, so that the next context we search for handlers is the outer
2907 context instead of the context that had the call to __throw, if we
2908 don't immediately find the desired context.
2910 Tue Aug 8 17:44:23 1995 Jason Merrill <jason@phydeaux.cygnus.com>
2912 * tree.c (cp_expand_decl_cleanup): Returns int, not tree.
2913 * cp-tree.h: Update.

2925 (throw_label): Removed.
2926 (expand_builtin_throw): Changed so that EH parameters are passed by
2927 normal function call conventions. Completes Aug 4th work.
2929 Fri Aug 4 17:17:08 1995 Mike Stump <mrs@cygnus.com>
2931 * cp-tree.h (expand_builtin_throw): Declare it.
2932 * decl2.c (finish_file): Call expand_builtin_throw.
2933 * except.c (make_first_label): Remove.
2934 (init_exception_processing): Don't use a LABEL_REF for throw_label,
2935 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
2936 other functions that don't really appear in those functions. This
2937 solves a problem where cc1plus consumed exponential amounts of
2938 memory when -Wall was used.
2939 (expand_end_all_catch, expand_leftover_cleanups,
2940 expand_end_catch_block, expand_throw): Change all uses of
2941 throw_label to match new style.
2942 (do_unwind): Rename parameter to inner_throw_label, as it is now
2943 different from throw_label. Also, assume that our caller will wrap
2944 the passed label with a LABEL_REF, if needed.
2945 (expand_builtin_throw): Make external, change so that the generated
2946 throw is now a real function.
2947 (expand_exception_blocks): Never generate throw code inside another

2952 * decl.c (grokdeclarator): Move checking of mutable const objects
2953 and mutable static objects down, as we might decide during parsing
2954 to unset staticp or constp (for example, when const is part of the
2955 object being pointed to).
2957 Thu Aug 3 17:13:43 1995 Mike Stump <mrs@cygnus.com>
2959 * except.c (output_exception_table_entry): Enhance portability to
2961 (emit_exception_table): Ditto.

2971 and const T all match.
2973 Wed Aug 2 11:25:33 1995 Mike Stump <mrs@cygnus.com>
2975 * except.c (build_eh_type): Strip cv qualifiers so that const T&,
2976 T&, T and const T all match.

2980 * except.c: Fix up comments, cleanup code and eliminate exceptNode,
2981 exceptStack, exceptstack, push_except_stmts, pop_except_stmts,
2982 new_except_stack, push_last_insn, pop_last_insn, insn_save_node and
2983 InsnSave. Also, numerous speed improvements, and correctness
2984 improvements. Double faulting in all situations should now be
2986 (expand_start_all_catch): Instead of having many terminate protected
2987 regions, just have one.
2988 (expand_start_catch_block): No longer have to protect
2989 false_label_rtx, as it isn't used for EH region marking.
2990 (expand_end_catch_block): Expand out EH cleanups here by using
2991 expand_leftover_cleanups.
2992 (expand_end_all_catch): Use sequences instead of playing with insn
2994 (expand_exception_blocks): Ditto. Also protect all catch clauses
2995 with one terminate region.
2997 Mon Jul 31 13:24:30 1995 Jason Merrill <jason@phydeaux.cygnus.com>
2999 * method.c (report_type_mismatch): Don't talk about an object
3000 parameter for non-methods.

3022 (pushdecl): Build up the list.
3023 (hack_incomplete_structures): Walk it and prune completed decls.
3025 Fri Jul 28 15:26:44 1995 Jason Merrill <jason@phydeaux.cygnus.com>
3027 * typeck.c (comp_target_types): Don't check const and volatile for

3044 * tree.c (unsave_expr): New routine to build an UNSAVE_EXPR.
3045 (unsave_expr_now): Backend routine used by tree expander.
3046 (cp_expand_decl_cleanup): Wrap second argument in an UNSAVE_EXPR to
3047 work around a limitation in the backend. The backend uses the
3048 cleanups multiple times, on disjoint control flows, so we cannot
3049 pass unsaved SAVE_EXPRs to the backend.
3050 * tree.def (UNSAVE_EXPR): New tree code.
3051 * typeck.c (c_expand_return): Move goto/return code up inside
3052 conditional, as we don't always want to do this, we only want to do
3053 this when we don't otherwise finish with this control flow.
3055 Thu Jul 27 10:38:43 1995 Brendan Kehoe <brendan@lisa.cygnus.com>

5296 * parse.y (do_xref): Lose.
5297 (named_class_head): If we see 'class foo:' we know it's a
5298 definition, so don't worry about base lists for non-definitions.

5360 initializers are done as tdecls are initialized in the global
5361 initializer. Also Pick up any new tdecls or vtables needed by
5362 synthesized methods.
5364 * class.c (finish_struct): Simplify. We have to do rtti scanning at
5365 end, so we might as well do all of it there.

5369 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

5379 * decl2.c (finish_file): Call finish_prevtable_vardecl.
5380 * gc.c (build_generic_desc): Allow it to be called when not at the

5382 (build_t_desc): Rearrange a bit so that it really works and is
5384 * class.c (finish_struct): Don't decide on tdecls here, as we have
5385 to wait until the end of the file in general to decide whether or

5419 * decl2.c (finish_vtable_vardecl): Now set the
5420 interface/implementation of vtables on the first virtual function,
5421 if one exists, otherwise we use the old method. This is a major win
5422 in terms of cutting down the size of objects and executables in
5423 terms of text space and data space. Now most of the savings that
5424 #pragma interface/implementation gives is automatic in a fair number

5443 * parse.y: Add END_OF_LINE token.
5445 * lex.c (check_newline): Set linemode when we see a # directive, and
5446 unset it when we're done. Turn all 'return's into 'goto skipline'.
5447 Fix all uses of '\n', since we won't see it anymore. Put back the
5448 character we read before checking for a sysv or target pragma.
5449 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.

5486 * typeck.c (convert_for_assignment): Initialize variable before use.

5610 they have the same precision.
5612 * decl.c (grokparms): Call convert_for_initialization to check
5615 * init.c (build_new): void_type_node has a size (of 0).

9281 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,

9296 their args. If vec delete takes the optional size_t argument, set
9297 TYPE_VEC_DELETE_TAKES_SIZE.
9298 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
9299 checking for one delete or the other.
9300 (lang_type): gets_new and gets_delete are now two bits long. The

9303 delete defined by this class wants to know how much space it is
9305 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must

9321 syntax errors nicely, since they break parsing of 'const i;'.

9326 * search.c (lookup_nested_tag): Look in enclosing classes, too.

9331 * lex.c (check_newline): Read first nonwhite char before
9332 incrementing lineno.
9334 * decl.c (grokdeclarator): Don't claim that typedefs are variables
9337 * parse.y: Divide up uses of unqualified_id into
9338 notype_unqualified_id and unqualified_id, so that TYPENAME can be
9339 used as an identifier after an object.
9341 * class.c (push_nested_class): Don't push into non-class scope.
9343 * decl.c (grokdeclarator): If an identifier could be a type
9344 conversion operator, but has no associated type, it's not a type
9345 conversion operator.
9347 * pt.c (unify): Check for equality of constants better.
9349 * decl.c (grokdeclarator): Don't complain about access decls.

9359 (nomods_initdecls): For decls without any mods, so that we don't try
9360 to get declspecs from some arbitrary $0.
9362 * search.c (lookup_field): Use cp_error.
9364 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
9365 here; it breaks destructors for non-aggr types.
9367 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
9368 a type being defined, like the comment says.
9369 If got_scope is not an aggregate, just return NULL_TREE.
9371 * pt.c (create_nested_upt): Kung's code for creating types nested
9372 within uninstantiated templates now lives here (it used to live in
9373 hack_more_ids). It needs to be expanded.
9375 * parse.y: Stop calling see_typename so much.
9377 * decl.c (lookup_name): Deal with TTPs and UPTs.
9379 * lex.c (real_yylex): Don't set looking_for_typename just because we
9381 (dont_see_typename): #if 0 out.
9383 * spew.c (yylex): Increment looking_for_typename if the next
9384 character is SCOPE, rather than setting it to 1; this way, the value
9385 from seeing an aggr specifier will not be lost. This kinda relies
9386 on looking_for_typename never being < 0, which is now true.
9388 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
9390 (named_class_head_sans_basetype): Accept template types, too. Oops.
9392 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
9394 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
9396 * parse.y: Lose START_DECLARATOR.
9398 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
9401 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
9402 A::foo' syntax. Catch invalid scopes better.
9404 * parse.y, lex.c: lose TYPENAME_COLON.
9406 * decl2.c (groktypefield): #if 0 out.
9408 * decl.c (lookup_name): If the type denoted by got_scope is
9409 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
9411 * class.c (push_nested_class): Don't try to push into
9414 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
9416 * Makefile.in (stamp-parse): Update count of conflicts to 33.
9418 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
9420 A saner implementation of nested types that treats template types
9421 no differently from non-template types. There are still some
9422 shortcomings of our system; most notably, it is difficult to look
9423 for a nested type that is hidden by another name, because of the way
9424 we keep track of hidden types. But this shouldn't be a problem for
9425 just about anyone. Perhaps lookup_field should be fixed up a bit.
9427 * spew.c: Moved handling of nested types/scoping from the lexer
9428 into the parser. Removed variable template_type_seen_before_scope.
9429 Removed functions frob_identifier, hack_more_ids, and various cruft
9430 that was #if 0'd out in the past, reducing the size of the file from
9431 1146 lines to 450 lines. We can't quite do away with spew.c yet,
9432 though; we still need it for do_aggr () and checking for SCOPE after
9433 the current identifier. And setting lastiddecl.
9435 * parse.y: Moved handling of nested types/scoping from the lexer
9436 into the parser, using a new global variable `got_scope'. Reduced
9437 the number of states by 53. Implemented all uses of explicit global
9438 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
9439 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
9440 scoped_typename. Added nonterminals nested_type,
9441 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
9442 nested_name_specifier, global_scope, overqualified_id, type_name.
9443 Changed many others. Added 9 new reduce/reduce conflicts, which are
9444 nested type parallels of 9 that were already in the grammar for
9445 non-nested types. Eight of the now 33 conflicts should be removed
9446 in the process of resolving the late binding between variable and
9449 * gxxint.texi (Parser): Update.
9451 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
9453 * lex.h: Add decl for got_scope.
9455 * lex.c (see_typename): Claim to be the lexer when calling
9458 * decl.c (lookup_name): When called from the lexer, look at
9459 got_scope and looking_at_typename; otherwise don't.
9461 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
9463 31th Cygnus<->FSF merge.
9465 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
9467 * decl2.c (mark_vtable_entries): Call this to mark all the
9468 entries in the vtable addressable.

9476 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.

9480 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
9483 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
9485 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
9486 ch-tree.h: Every place these functions were called, the result was
9487 immediately passed to expand_expr_stmt. Reduce redundancy by
9488 calling expand_expr_init *inside* these functions. These
9489 makes for a simpler interface, and we don't have to build
9490 compound expressions. Hence, rename these function to:
9491 expand_virtual_init and expand_vbase_vtables_init respectively.
9492 * init.c, decl.c: Change callers of these functions.
9493 * init.c, cp-tree.h (expand_virtual_init): Make static.
9495 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
9496 rather than DECL_SAVED_INSNS before emitting inlines.

9500 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.

9503 extern "C" function, keep the type (for the argtypes).
9504 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
9505 (decls_match): Call compparms with a value of strict dependent on
9506 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
9508 * typeck.c (compparms): ... is only equivalent to non-promoting
9509 parms if we're not being strict.
9511 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
9513 * decl.c (init_decl_processing): if (flag_ansi || pedantic)

9526 * class.c (build_vtable_entry): Build thunk if necessary.
9527 * class.c (build_vfn_ref): If using thunks, don't need
9528 to add delta field from vtable (there is none!).
9529 * decl.c: Add memptr_type as well as vtable_entry_type.
9530 If using thunks, the latter is just ptr_type_node.
9531 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
9532 * decl2.c (finish_vtable_vardecl): Handle thunks.
9533 * expr.c (cplus_expand_expr): Support THUNK_DECL.
9535 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
9536 * decl.c (start_function): Set current_extern_inline based on
9537 DECL_THIS_EXTERN, not TREE_PUBLIC.
9538 * decl.c (finish_function): Call mark_inline_for_output if needed,
9540 Improve intelligence about when to emit inlines.
9541 * cp-tree.h (lang_decl_flags): New field saved_inline.

9546 * decl2.c (mark_inline_for_output): Do nothing if
9547 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
9548 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
9549 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
9550 * decl2.c (finish_file): Writing out inlines later, so we can
9551 also handle the ones needed for vtbales.
9552 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
9554 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
9555 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
9556 instead. (The rationale is that these optimizations both break binary
9557 compatibility, but should become the default in a future release.)
9559 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
9561 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
9562 of a fndecl, as we might not be from that vfield.
9564 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
9566 * class.c (add_virtual_function): fix bug for pure virtual, so
9567 that DECL_VINDEX of the dummy decl copied won't be error.
9568 (see also Apr 4 change)
9570 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
9572 * typeck.c (c_expand_return): Before checking that we're not
9573 returning the address of a local, make sure it's a VAR_DECL.
9574 (And don't worry about it being a TREE_LIST.)
9576 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
9578 * parse.y (YYDEBUG): Always define.
9579 * lex.c (YYDEBUG): Ditto.
9581 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
9583 * class.c (finish_struct): backup out the change below, put the
9584 new change for the same purpose. The change below breaks code.
9586 * class.c (finish_struct): if pure virtual, copy node and make
9587 RTL point to abort, then put in virtual table.
9588 * decl2.c (grok_function_iit): reinstate Mar 31 change.

9592 * init.c (build_new): pedwarn about newing const and volatile
9595 * tree.c (get_identifier_list): Only do the special handling
9596 thing if we're dealing with the main variant of the record type.
9598 * cvt.c (convert_to_reference): When converting between
9599 compatible reference types, use the pointer conversion machinery.
9600 Don't just blindly overwrite the old type.

9604 * call.c (build_method_call): When looking at global functions,
9605 be sure to use instance_ptr for the first argument, not some version
9606 of it that has been cast to a base class. Also do this before
9607 comparing candidates.

9611 * call.c (build_method_call): Constructors can be called for

9717 when warning about re-friending.
9719 * pt.c (tsubst): Use comptypes rather than == to compare the
9720 types of the method as declared and as defined, since default
9721 parameters may be different.
9723 * call.c (build_method_call): Use brendan's candidate printing
9726 * decl.c (start_method): Methods defined in the class body are
9727 inline whether or not it's a template class.

9746 (start_function): Ditto.
9747 (push_overloaded_decl): Don't check for overloaded C functions.
9749 * *.c: Stop using DECL_OVERLOADED, it being archaic.

9892 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl
9893 if it was a definition.
9894 (redeclaration_error_message): Do the cp_error thang, and reject
9895 redefinition of templates.
9897 Mon Mar 21 19:36:06 1994 Per Bothner (bothner@kalessin.cygnus.com)
9899 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
9900 in FIELD context, when appropriate. Also,
9901 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
9902 Also, simplify check for bogus return specifiers.
9904 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
9906 * parse.y (after_type_declarator1): Expand type_quals.
9907 (notype_declarator1): Ditto.
9910 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
9912 * decl.c (grokdeclarator): Treat class-local typedefs like static
9913 members; i.e. 'typedef int f();' means that f is a function type,
9916 * parse.y (decl): Change direct_* back to *.
9917 (type_id): Change direct_abstract_declarator to absdcl.
9918 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.
9920 Fri Mar 18 12:47:59 1994 Jason Merrill (jason@deneb.cygnus.com)
9922 These two patches fix crashes on instantiating a template inside a
9923 function with C linkage or containing labels.
9925 * class.c (current_lang_stacksize): No longer static.
9927 * decl.c (struct saved_scope): Add lang_base, lang_stack,
9928 lang_name, lang_stacksize, and named_labels.
9929 (push_to_top_level): Save them.
9930 (pop_from_top_level): Restore them.
9932 * gxxint.texi (Parser): Update.
9934 These two patches finish moving the task of expr/declarator
9935 ambiguity resolution from the lexer to the parser, and add one more
9936 r/r conflict. START_DECLARATOR can now be nuked.
9938 * parse.y (decl): Add "direct_" in typespec X rules.
9939 (direct_declarator): New nonterminal for
9940 direct_after_type_declarator and direct_notype_declarator.
9941 (direct_initdecls): Like initdecls, but uses direct_initdcl0.
9942 (direct_initdcl0): Like initdcl0, but uses direct_declarator.
9943 (named_parm): Add typespec direct_declarator rule.
9945 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
9947 These two patches disable some excessive cleverness on the part of
9948 g++; a non-class declaration always hides a class declaration in the
9949 same scope, and g++ was trying to unhide it depending on the
9950 enclosing expression.
9952 * spew.c (arbitrate_lookup): #if 0 out.
9954 * decl.c (lookup_name): Never call arbitrate_lookup.
9956 * parse.y (complex_notype_declarator1): Add '*'
9957 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
9959 * parse.y (complex_direct_notype_declarator): Restore id_scope
9960 see_typename TYPENAME rule, remove all other rules beginning with
9962 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
9964 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
9966 These changes fix the compiler's handling of the functional cast/
9967 object declaration ambiguities in section 6.8 of the ARM. They also
9968 add 11 reduce/reduce conflicts. Sigh.
9970 * parse.y: Add precedence decls for OPERATOR and '~'.
9971 (notype_unqualified_id): New nonterminal, encompasses all of the
9972 ANSI unqualified-id nonterminal except TYPENAMEs.
9973 (expr_or_declarator): New nonterminal to delay parsing of code like
9975 (primary): Use notype_unqualified_id.
9976 (decl): Add typespec initdecls ';' and typespec declarator ';'
9978 (initdcl0): Deal with the above.
9979 (complex_notype_declarator1): A notype_declarator that is not also
9980 an expr_or_declarator.
9981 (complex_direct_notype_declarator): A direct_notype_declarator that
9982 doesn't conflict with expr_or_declarator. Use
9983 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
9984 (functional_cast): New nonterminal, for the three functional cast
9985 rules. So that they can be moved after
9986 complex_direct_notype_declarator.
9987 (see_typename): Don't accept type_quals any more.
9989 * decl2.c (reparse_decl_as_expr): New function to deal with parse
9990 nodes for code like `int (*a)++;'.
9991 (reparse_decl_as_expr1): Recursive subroutine of the above.
9992 (finish_decl_parsing): New function to deal with parse nodes for
9993 code like `int (*a);'. See the difference?
9995 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
9997 These changes break binary compatibility in code with classes
9998 that use virtual bases.
10000 * search.c (dfs_get_vbase_types): Simplify and correct to make
10001 sure virtual bases are initialized in dfs ordering.
10002 * search.c (get_vbase_types): Simplify and make readable.
10004 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)
10006 * parse.y: s/ typename / type_id /g
10008 Wed Mar 16 17:42:52 1994 Kung Hsu (kung@mexican.cygnus.com)
10010 * parse.y (typespec): add SCOPE TYPENAME for global scoped
10013 * decl.c (complete_array_type): fix a bug that in -pendantic
10014 mode even there's no initializer, it will continue to build
10017 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
10019 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
10020 all of the scoped PTYPENAME rules.
10022 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
10024 * init.c (build_offset_ref): The value of A::typedef_name is
10025 always the TYPE_DECL, and never an error.
10027 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
10029 * search.c (get_base_distance_recursive): Two binfos can only
10030 represent the same object if they are both via_virtual.
10032 * class.c (finish_base_struct): Check vbases for ambiguity, too.
10034 * search.c (get_vbase_types): Accept binfo argument, too.
10036 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
10038 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
10039 initializer also, because back-end requires it.
10041 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
10043 * error.c (dump_expr): Support member functions (which show up as
10046 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>
10048 * init.c (build_new): Set the return type of multidimensional
10051 Fri Mar 11 15:35:39 1994 Kung Hsu (kung@mexican.cygnus.com)
10053 * call.c (build_method_call): if basetype not equal to type
10054 of the instance, use the type of the instance in building
10057 Thu Mar 10 17:07:10 1994 Kung Hsu (kung@mexican.cygnus.com)
10059 * parse.y (direct_notype_declarator): add push_nested_type for
10060 'template_type SCOPED_NAME' rule.
10062 Tue Mar 8 00:19:58 1994 Jason Merrill (jason@deneb.cygnus.com)
10064 * parse.y (parm): Add typed_declspec1 {absdcl, epsilon} rules.
10066 Sat Mar 5 04:47:48 1994 Jason Merrill (jason@deneb.cygnus.com)
10068 * parse.y (regcast_or_absdcl): New nonterminal to implement late
10069 reduction of constructs like `int ((int)(int)(int))'.
10070 (cast_expr): Use it.
10071 (sub_cast_expr): Everything that can come after a cast.
10072 (typed_declspecs1): typed_declspecs that are not typed_typespecs.
10073 (direct_after_type_declarator): Lose PAREN_STAR_PAREN rule.
10074 (direct_abstract_declarator): Replace '(' parmlist ')' rule with
10075 '(' complex_parmlist ')' and regcast_or_absdcl.
10077 (complex_parmlist): Parmlists that are not also typenames.
10078 (parms_comma): Enabler.
10079 (named_parm): A parm that is not also a typename. Use declarator
10080 rather than dont_see_typename abs_or_notype_decl. Expand
10081 typed_declspecs inline.
10082 (abs_or_notype_decl): Lose.
10083 (dont_see_typename): Comment out.
10084 (bad_parm): Break out abs_or_notype_decl into two rules.
10086 Fri Mar 4 18:22:39 1994 Jason Merrill (jason@deneb.cygnus.com)
10088 * decl2.c (reparse_decl_as_casts): New function to change parse
10089 nodes for `(int)(int)(int)' from "function taking int and returning
10090 function taking int and returning function taking int" to "... cast
10091 to int, cast to int, cast to int".
10093 * decl2.c (reparse_decl_as_expr): Recursive function to change
10094 parse nodes for `A()()' from "function returning function returning
10095 A" to "A().operator()".
10097 * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
10098 `typespec fcast_or_absdcl' rule.
10099 (fcast_or_absdcl): New nonterminal to implement late reduction of
10100 constructs like `A()()()()'.
10101 (typename): Replace `typespec absdcl1' rule with
10102 `typespec direct_abstract_declarator' rule.
10103 (direct_abstract_declarator): Replace `LEFT_RIGHT type_quals' rule
10104 with `fcast_or_absdcl type_quals' rule.
10106 Fri Mar 4 16:18:03 1994 Mike Stump <mrs@cygnus.com>
10108 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
10109 matches Section 5.5.
10111 Fri Mar 4 14:01:59 1994 Jason Merrill (jason@deneb.cygnus.com)
10113 * error.c (dump_type_prefix): Don't print basetype twice for
10116 Fri Mar 4 13:24:33 1994 Mike Stump <mrs@cygnus.com>
10118 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
10119 so that it is like setHandler(&A::handlerFn). Cures an `invalid
10120 lvalue in unary `&''.
10122 Fri Mar 4 11:15:59 1994 Jason Merrill (jason@deneb.cygnus.com)
10124 * gxxint.texi (Copying Objects): New section discussing default
10125 op= problems with virtual inheritance.
10127 * decl2.c (grokoptypename): Just does grokdeclarator and
10128 build_typename_overload, since the parser can't call grokdeclarator
10131 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
10132 and TREE_TYPE on generated identifiers.
10134 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.
10136 * parse.y (parm): Convert `const char *' to `__opPCc' here.

10139 if we can't figure out what to do.
10140 (dump_type*): Ditto.
10142 * typeck2.c (build_m_component_ref): 'component' is an expr, not
10143 a decl. Also move the IS_AGGR_TYPE check after the stripping of

10148 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
10149 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid

10154 * parse.y: Add precedence specification for START_DECLARATOR.
10155 (type_quals): Move before primary.
10156 (typename): Move before typed_declspecs, add 'typespec absdcl1' rule.
10158 * decl2.c (grokoptypename): Lose.
10160 * decl.c (grokdeclarator): Parse TYPE_EXPRs in the initial scan,
10161 rather than waiting until later.
10163 Wed Mar 2 14:12:23 1994 Jason Merrill (jason@deneb.cygnus.com)
10165 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
10166 than expanding it inline.
10167 (typename): Expand empty option of (former) absdcl inline.
10168 (abs_or_notype_decl): Ditto.
10169 (absdcl): Lose empty rule.
10170 (conversion_declarator): New nonterminal for 'typename' of 'operator
10172 (operator_name): Use it instead of absdcl.
10174 * parse.y: Add precedence declarations for SCOPED_TYPENAME,
10176 (typed_declspecs): Accept typed_typespecs, rather than typespec
10177 directly. Add rules with reserved_typespecquals.
10178 (reserved_declspecs): Don't accept typespecqual_reserved at the
10179 beginning of the list. The typed_declspecs rule will deal with this
10181 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
10184 * parse.y (direct_notype_declarator,
10185 direct_after_type_declarator, direct_abstract_declarator): Split up
10186 the declarator1 nonterminals to match the draft standard and avoid
10188 (new_type_id, new_declarator, direct_new_declarator,
10189 new_member_declarator): New nonterminals to implement the subset of
10190 'typename' allowed in new expressions.

10202 (get_decl_list): Use it.
10203 (list_hash_lookup_or_cons): Ditto.
10205 * parse.y (typed_declspecs, declmods): It's not necessary to hash
10206 the declspecs on class_obstack, so don't. This way typed_typespecs
10207 can reduce to typed_declspecs.
10209 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
10211 * cvt.c (build_up_reference): If we aren't checking visibility,
10212 also allow base->derived conversions.
10214 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
10216 * typeck.c (build_c_cast): Remove bogus hack when converting

10227 and !CLASSTYPE_INTERFACE_KNOWN, try to use the presence of
10228 a non-inline virtual function to control emitting of vtables.
10229 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
10230 * search.c (build_vbase_vtables_init): Don't assemble_external
10231 (yet) if flag_vtable_hack.
10232 * class.c (build_vfn_ref): Ditto.
10234 Mon Feb 28 14:54:13 1994 Jason Merrill (jason@deneb.cygnus.com)
10236 * parse.y (component_decl): Don't include "typed_declspecs
10237 declarator ';'" speedup, since it breaks enums.

10241 * class.c (finish_struct): Minor optimization for building

10248 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
10250 * lex.c (check_newline): #pragma interface can take a string
10251 argument, just like #pragma implementation. #pragma implementation
10252 checks for garbage on the line, line #pragma interface does. Main
10253 input files do not auto implement like named files, #pragma
10254 implementation must be used explicitly.
10256 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
10258 * parse.y (components): Handle list of one again.

10268 * Makefile.in (stamp-parse): Update expected conflict count.
10270 * parse.y (various): Replace "declmods declarator" with "declmods
10271 notype_declarator". The comment saying that "declmods declarator ';'"
10272 corresponds to "int i;" was wrong; it corresponds to "const i;".
10273 (component_decl): Add "typed_declspecs declarator ';'" rule; this
10274 *does* correspond to "int i;". Change "declmods components" to
10275 "declmods notype_components".
10276 (components): Don't deal with a list of one anymore.
10277 (notype_components): New nonterminal, corresponds to notype_declarator.

10286 Eliminates four reduce/reduce conflicts.
10288 (named_class_head): Move intermediate code block into separate
10289 nonterminal so that we can stick %prec EMPTY on it.
10291 Add more %prec EMPTY's to eliminate remaining shift/reduce
10294 (after_type_declarator): Add maybe_raises to fndecl rules.
10295 (after_type_declarator_no_typename): Remove.
10298 Document remaining reduce/reduce conflicts.

10302 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
10303 (TYPE_BINFO (type)) if we care about the path.
10305 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
10308 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>
10310 * Makefile.in (mostlyclean): lex.c is a source file, don't
10313 Sat Feb 19 01:27:14 1994 Jason Merrill (jason@deneb.cygnus.com)
10315 * parse.y: Eliminate 20 shift/reduce conflicts.
10317 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
10319 * pt.c (type_unification): Add subr argument; if set, it means
10320 that we are calling ourselves recursively, so a partial match is OK.
10321 (unify): Support pointers to methods and functions.
10322 (tsubst): Support method pointers.
10323 * decl.c (build_ptrmemfunc_type): No longer static, so that
10324 tsubst can get at it.
10326 * init.c (is_aggr_typedef): Pretend template type parms are
10328 * decl2.c (build_push_scope): If cname refers to a template type
10329 parm, just grin and nod.
10331 * call.c (build_overload_call_real): Pass subr argument to
10333 * pt.c (do_function_instantiation): Ditto.
10334 * class.c (instantiate_type): Ditto.
10336 * search.c (get_base_distance): If BINFO is a binfo, use it and
10337 don't mess with its BINFO_INHERITANCE_CHAIN.
10339 * cvt.c (convert_to_reference): Fix temporary generation.
10340 If ambiguous, return error_mark_node.
10342 * init.c (build_new): Put back some necessary code.
10344 Thu Feb 17 15:39:47 1994 Jason Merrill (jason@deneb.cygnus.com)
10346 * init.c (build_new): Deal with array types properly.

10352 (get_base_distance): Ditto.
10354 * parse.y (explicit_instantiation): Syntax is 'template class
10355 A<int>', not 'template A<int>'.
10357 * typeck.c (convert_for_initialization): Remove bogus warning.
10359 * parse.y (datadef): Revert patch of Oct 27.
10361 Thu Feb 17 15:12:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
10363 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,
10364 rather than integer_type_node. Does wonders for the Alpha.
10366 Thu Feb 17 13:36:21 1994 Jason Merrill (jason@deneb.cygnus.com)
10368 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
10369 goes onto the same obstack as its target type.
10371 Wed Feb 16 00:34:46 1994 Jason Merrill (jason@deneb.cygnus.com)
10373 * cvt.c (convert_to_reference): If converting via constructor
10374 on local level, go back to build_cplus_new approach.
10376 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
10377 to error_mark_node to prevent expand_expr from building a cleanup
10380 * lex.c (default_assign_ref_body): Return *this from the memcpy
10383 * decl.c (grok_reference_init): Just return if called with
10384 error_mark_node, don't worry about initializing non-const reference
10387 * cvt.c (convert_to_reference): Do the right thing for
10388 non-aggregate reference conversions, pedwarn when generating a
10389 non-const reference to a temporary.

10398 convert_to_reference. Generally do the right thing.
10400 * cvt.c (convert_to_reference): Conform to the initial comment;
10401 i.e. don't create temps if decl != error_mark_node. Handle
10402 cleanups better for temps that do get created. Don't pretend

10424 Remove NEW_CLASS_SCOPING, assuming it is always 1.

10921 current_class_type and current_function_decl is the most nested.
10922 (compute_access): Total overhaul to make it clearer and more
10923 correct. Don't use the cache for now; in the only situation where
10924 it was used before, it gained nothing. This frees up three of the
10925 DECL_LANG_FLAGs for possible other use!

11266 to check if two fndecls are `the same'. Sometimes this routine can
11267 modify the main vtable, and normal should be 1, in that case, so use
11268 is_normal() to determine if this is the main vtable for the class.

11270 care of them elsewhere.

11314 (lang_decode_option): Set warn_return_type, not explicit_*, for
11315 -Wreturn-type and -Wall. This is what rest_of_compilation uses to

11318 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
11319 (finish_function): Also complain about no return in a non-void fn if
11320 we're being pedantic (don't rely on use of -Wreturn-type).

11377 * cp-class.c (finish_base_struct): Set cant_synth_* correctly.
11378 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
11379 properly with the case where a class contains an object of an
11380 ambiguous base class which has a protected op=. Should be fixed
11381 when the access control code gets overhauled.
11382 (finish_struct_methods): Set TYPE_HAS_NONPUBLIC_* correctly.
