2608 * except.c: Always allow turning on exception handling. Allow cross

2635 Tue Aug 22 17:20:07 1995 Per Bothner <bothner@kalessin.cygnus.com>
2637 * decl2.c (flag_new_for_scope): Add a new mode that follows ANSI
2638 for-scoping, but supports (and warns about) old programs.
2639 Make the new mode (with value 1) the default.
2640 (lang_f_options): The on-value for flag_new_for_scope is now 2.
2641 * cp-tree.h (DECL_DEAD_FOR_LOCAL, DECL_ERROR_REPORTED): New macros
2642 (DECL_SHADOWED_FOR_VAR): Likewise.

2652 Mon Aug 21 10:28:31 1995 Jason Merrill <jason@deneb.cygnus.com>
2654 * decl2.c (import_export_inline): Class interface hackery does not

2659 * search.c (virtual_context): Find the right context more often.
2660 Solves a `recoverable compiler error, fixups for virtual function'
2663 Sun Aug 20 13:53:24 1995 Mike Stump <mrs@cygnus.com>
2665 * except.c (expand_start_all_catch): Ensure that we always transfer
2666 control to the right EH handler, by rethrowing the end label on the
2667 region, instead of hoping we are nested and falling through.
2668 (expand_leftover_cleanups): Ditto.
2669 (end_protect): Since we now rethrow the end label, put a
2670 nop after it, so that outer regions are recognized.
2671 * init.c (build_vec_delete_1): New routine to handle most of vector
2672 deleting, all code moved here from build_vec_delete.
2673 (build_array_eh_cleanup): Use build_vec_delete_1 to do all the real

2676 EH region to handle it.

2678 build_vec_delete_1 to do the grunt work.
2680 Sat Aug 19 14:25:33 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2682 Handle decl attributes properly for function definitions without
2683 previous attribute-loaded declarations.

2686 * cp-tree.h (start_function): Update prototype.
2687 * parse.y (fn.def1): Pass ATTRS into start_function instead of

2690 * decl2.c (finish_file): Pass NULL_TREE as fourth arg to
2692 * method.c (synthesize_method): Likewise.
2693 * except.c (expand_builtin_throw): Likewise for start on __throw.
2695 Sat Aug 19 13:36:08 1995 Mike Stump <mrs@cygnus.com>
2697 * class.c (set_rtti_entry): Turn on -fvtable-thunk -frtti support.
2698 This changes -fvtable-thunks vtable layout, so a recompile will be
2699 necessary, if you use -fvtable-thunks.
2700 (get_vtable_entry): Use n, instead of i to be consistent with the
2701 rest of the compiler.
2702 (get_vtable_entry_n): Ditto.

2718 * gc.c (build_headof): Support -fvtable-thunk and -frtti together.

2735 can be used for class template definitions, as well.
2736 (finish_struct_1): New function with the rest of the code.
2738 Tue Aug 15 09:46:16 1995 Mike Stump <mrs@cygnus.com>
2740 * class.c (prepare_fresh_vtable): On second though, always build the
2741 offset (see Aug 10 change), unless -fvtable-thunks is given. It
2742 does this by calling the new routine set_rtti_entry.
2743 (finish_struct): Ditto.
2744 (set_rtti_entry): New routine to update the rtti information at the
2745 start of the vtable.
2747 Mon Aug 14 12:21:22 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2749 * error.c (dump_decl, case IDENTIFIER_NODE): Only work on a dtor
2750 if it's declared in the C++ language spec.
2751 (dump_function_decl): Likewise.
2752 (dump_function_name): Likewise.
2753 (ident_fndecl): Make sure we got something back from lookup_name.
2754 * decl.c (start_function): Likewise.
2756 Fri Aug 11 16:52:15 1995 Jason Merrill <jason@phydeaux.cygnus.com>
2758 * call.c (build_method_call): Don't call build_new when calling a
2759 constructor without an instance.

2763 * class.c (prepare_fresh_vtable): Always build the offset to the
2764 complete object, as it doesn't cost much. This allows dynamic_cast
2765 to void * to work when -frtti isn't given.
2766 (finish_struct): Ditto.
2768 Thu Aug 10 16:31:28 1995 Mike Stump <mrs@cygnus.com>
2770 * except.c (build_eh_type): Split out some functionality to new
2771 routine named build_eh_type_type.
2772 (build_eh_type_type): New routine.
2773 (expand_start_catch_block): Use build_eh_type_type, as we never want
2774 the dynamic type of the catch parameter, just the static type.
2775 Fixes core dumps when -frtti is used and one catchs pointers to
2778 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
2780 * except.c (expand_builtin_throw): Since we now use normal calling
2781 conventions for __throw, we have to remove the first layer off the
2782 stack, so that the next context we search for handlers is the outer
2783 context instead of the context that had the call to __throw, if we
2784 don't immediately find the desired context.
2786 Tue Aug 8 17:44:23 1995 Jason Merrill <jason@phydeaux.cygnus.com>
2788 * tree.c (cp_expand_decl_cleanup): Returns int, not tree.

2809 * except.c (make_first_label): Remove.
2810 (init_exception_processing): Don't use a LABEL_REF for throw_label,
2811 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
2812 other functions that don't really appear in those functions. This
2813 solves a problem where cc1plus consumed exponential amounts of
2814 memory when -Wall was used.
2815 (expand_end_all_catch, expand_leftover_cleanups,
2816 expand_end_catch_block, expand_throw): Change all uses of
2817 throw_label to match new style.
2818 (do_unwind): Rename parameter to inner_throw_label, as it is now
2819 different from throw_label. Also, assume that our caller will wrap
2820 the passed label with a LABEL_REF, if needed.
2821 (expand_builtin_throw): Make external, change so that the generated
2822 throw is now a real function.
2823 (expand_exception_blocks): Never generate throw code inside another

2828 * decl.c (grokdeclarator): Move checking of mutable const objects
2829 and mutable static objects down, as we might decide during parsing
2830 to unset staticp or constp (for example, when const is part of the
2831 object being pointed to).
2833 Thu Aug 3 17:13:43 1995 Mike Stump <mrs@cygnus.com>
2835 * except.c (output_exception_table_entry): Enhance portability to
2837 (emit_exception_table): Ditto.

2857 exceptStack, exceptstack, push_except_stmts, pop_except_stmts,
2858 new_except_stack, push_last_insn, pop_last_insn, insn_save_node and
2859 InsnSave. Also, numerous speed improvements, and correctness
2860 improvements. Double faulting in all situations should now be
2862 (expand_start_all_catch): Instead of having many terminate protected
2863 regions, just have one.
2864 (expand_start_catch_block): No longer have to protect
2865 false_label_rtx, as it isn't used for EH region marking.
2866 (expand_end_catch_block): Expand out EH cleanups here by using
2867 expand_leftover_cleanups.
2868 (expand_end_all_catch): Use sequences instead of playing with insn
2870 (expand_exception_blocks): Ditto. Also protect all catch clauses
2871 with one terminate region.

2923 work around a limitation in the backend. The backend uses the
2924 cleanups multiple times, on disjoint control flows, so we cannot
2925 pass unsaved SAVE_EXPRs to the backend.
2926 * tree.def (UNSAVE_EXPR): New tree code.
2927 * typeck.c (c_expand_return): Move goto/return code up inside
2928 conditional, as we don't always want to do this, we only want to do
2929 this when we don't otherwise finish with this control flow.
2931 Thu Jul 27 10:38:43 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
2933 * parse.y (typespec): Only complain about typeof if we're not

2981 * decl.c (start_decl): Handle declarations of member functions
2982 outside of the class (i.e. specialization declarations).

2993 is not a parameter list (TREE_LIST).
2994 (expand_default_init): If LOOKUP_ONLYCONVERTING is set, then set
2995 LOOKUP_NO_CONVERSION so that we don't allow two-level conversions,
2996 but don't set it otherwise.

3000 * init.c (expand_default_init): Don't allow two-level conversions

3044 according to the new layout. Set the vb_off field to -1 for now.
3046 * decl.c (init_decl_processing): Align sigtable_entry_type on word

3388 (init_decl_processing): Initialize these variables.
3389 (init_decl_processing): Use these variables to build the
3390 sigtable_entry_type structure. Rename the code and offset fields

3411 pt.c (coerce_template_parms): Ditto.
3412 (push_template_decls): Ditto.
3413 (grok_template_type): Deleted as template parameters are shared

4600 (expand_aggr_vbase_init): Simplify.

5157 (pushdecl): Remove redundant set_nested_typename
5158 (xref_tag): Split out base handling into xref_basetypes.
5160 * cp-tree.h (TYPE_INCOMPLETE): New macro; TEMPLATE_TYPE_PARMs are
5161 not considered incomplete even though their definition is unknown.
5163 * decl.c (xref_defn_tag): Lose.
5164 (xref_tag): xref_next_defn = ! globalize.
5165 (pushdecl): Don't set DECL_NESTED_TYPENAME on artificial decls. The

5167 (pushdecl_class_level): Ditto.
5168 (pushtag): Tidy up a bit.
5169 (set_nested_typename): Push a decl for the nested typename from
5170 here, rather than from xref_defn_tag.
5172 * parse.y (do_xref): Lose.
5173 (named_class_head): If we see 'class foo:' we know it's a
5174 definition, so don't worry about base lists for non-definitions.
5176 * pt.c (push_template_decls): Template parm decls are artificial.
5178 * decl.c (duplicate_decls): Restore check for qualifier
5179 disagreement for non-functions.

5191 tacking on a NOP_EXPR.
5192 (convert_to_reference): Use comp_target_types instead of comptypes
5193 so that we don't allow conversions two levels down.

5209 * except.c: Add support for mips systems that don't define __mips

5235 (finish_file): Move finish_prevtable_vardecl up to before the global
5236 initializers are done as tdecls are initialized in the global
5237 initializer. Also Pick up any new tdecls or vtables needed by
5238 synthesized methods.
5240 * class.c (finish_struct): Simplify. We have to do rtti scanning at
5241 end, so we might as well do all of it there.

5245 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

5254 in finish_prevtable_vardecl.
5255 * decl2.c (finish_file): Call finish_prevtable_vardecl.
5256 * gc.c (build_generic_desc): Allow it to be called when not at the
5257 global binding layer, but behave as if we were.
5258 (build_t_desc): Rearrange a bit so that it really works and is
5260 * class.c (finish_struct): Don't decide on tdecls here, as we have
5261 to wait until the end of the file in general to decide whether or
5264 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

5293 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
5295 * decl2.c (finish_vtable_vardecl): Now set the
5296 interface/implementation of vtables on the first virtual function,
5297 if one exists, otherwise we use the old method. This is a major win
5298 in terms of cutting down the size of objects and executables in
5299 terms of text space and data space. Now most of the savings that
5300 #pragma interface/implementation gives is automatic in a fair number

5305 * decl.c (grokdeclarator): Discard the template parameters in a

5314 * decl2.c (check_classfn): If the cname is T<int> and fn_name is T,

5319 * parse.y: Add END_OF_LINE token.
5321 * lex.c (check_newline): Set linemode when we see a # directive, and
5322 unset it when we're done. Turn all 'return's into 'goto skipline'.
5323 Fix all uses of '\n', since we won't see it anymore. Put back the
5324 character we read before checking for a sysv or target pragma.
5325 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
5326 (handle_sysv_pragma): Don't look at the input stream; quit when we
5327 see an END_OF_LINE token.

5357 * pt.c (tsubst): When we copy a node, don't forget to copy

5362 * typeck.c (convert_for_assignment): Initialize variable before use.

8882 Thu Apr 21 18:27:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
8884 * cp-tree.h (THUNK_DELTA): It is normally negative, so
8885 use signed .i variant of frame_size rather than unsigned .u.
8886 * cp-tree.h (VTABLE_NAME_FORMAT): If flag_vtable_thunks,
8887 use "VT" rather than "vt" due to binary incompatibility.
8888 * class.c (get_vtable_name): Use strlen of VTABLE_NAME_FORMAT,
8889 rather than sizeof, since it is now an expression.
8890 * class.c (modify_one_vtable): Modify to skip initial element
8891 containing a count of the vtable.
8893 Thu Apr 21 00:09:02 1994 Jason Merrill (jason@deneb.cygnus.com)

8917 Tue Apr 19 22:25:41 1994 Mike Stump <mrs@cygnus.com>
8919 Reimplement vtable building, and most vtable pointer setting.

8940 * class.c (finish_struct): Added arguemnt to prepare_fresh_vtable
8941 call. General cleanup on how pending_hard_virtuals are handled.

8957 expand_indirect_vtbls_init. Change init_vtbl_ptrs call to
8958 expand_direct_vtbls_init.
8959 * init.c (expand_virtual_init): General cleanup.
8960 * init.c (expand_default_init): Change expand_vbase_vtables_init
8961 call to expand_indirect_vtbls_init.

8968 DECL_CONTEXT. That is now done in a cleaner way in
8969 modify_vtable_entry and add_virtual_function.
8970 * search.c (expand_vbase_vtables_init): Rename to
8971 expand_indirect_vtbls_init. General cleanup. Use
8972 expand_direct_vtbls_init to do hard work. Ensures that _all_ vtable
8973 pointers from virtual bases are set up.
8974 * search.c (bfs_unmark_finished_struct, unmark_finished_struct):
8977 * *.[chy]: Remove support for VTABLE_USES_MASK.
8979 Tue Apr 19 12:51:59 1994 Jason Merrill (jason@deneb.cygnus.com)
8981 * cvt.c (convert_to_reference): Use NOP_EXPRs to switch between
8982 reference and pointer types instead of bashing the types directly.
8984 * call.c (build_overload_call_real): Use the TREE_CODE to determine
8985 whether the function is overloaded or not, rather than
8987 * *: Remove all uses of TREE_OVERLOADED.
8989 * decl.c (grokdeclarator): Only complain about initializing const
8990 fields when -ansi or -pedantic.

9000 (struct binding_level): Add overloads_shadowed field.
9001 (poplevel): Restore overloads_shadowed.

9031 before we get to left_curly.
9032 * pt.c (instantiate_class_template): Set TYPE_BEING_DEFINED.
9034 * error.c (dump_decl): If it's a typedef, print out the name of the

9037 * decl.c (pushdecl): If the old duplicate decl was a TYPE_DECL,
9038 update the IDENTIFIER_TYPE_VALUE of its name.
9040 * decl2.c (finish_file): When processing the initializer for a
9041 static member, pretend that the dummy function is a member of the

9052 * typeck.c (build_conditional_expr): Pedwarn on pointer/integer
9053 mismatch, and don't pedwarn on 0/function pointer mismatch.
9055 * typeck2.c (digest_init): Lose code for special handling of unions.
9056 (process_init_constructor): Since they're handled just fine here.
9057 Pedwarn on excess elements.
9059 * decl2.c (grokfield): Complain about local class method declaration
9062 Fri Apr 15 13:19:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
9064 * method.c (emit_thunk): Add extern declaration for
9065 current_call_is_indirect (needed for hppa).
9067 Thu Apr 14 16:12:31 1994 Jason Merrill (jason@deneb.cygnus.com)
9069 Improve local class support; allow classes in different blocks to
9071 * decl.c (pushtag): Support local classes better.
9072 (pushdecl_nonclass_level): New function for pushing mangled decls of
9073 nested types into the appropriate scope.
9074 (xref_defn_tag): Use pushdecl_nonclass_level instead of
9076 (grokfndecl): Don't mess with IDENTIFIER_GLOBAL_VALUE for local
9078 * method.c (do_inline_function_hair): Ditto.
9080 * class.c (finish_struct): It is legal for a class with no
9081 constructors to have nonstatic const and reference members.
9083 Thu Apr 14 07:15:11 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
9085 * decl.c (push_overloaded_decl): Avoid giving errors about
9086 built-ins, since duplicate_decls will have given warnings/errors
9089 Thu Apr 14 03:45:12 1994 Jason Merrill (jason@deneb.cygnus.com)
9091 * cvt.c (convert_to_reference): Warn about casting pointer type to
9092 reference type when this is probably not what they wanted.
9094 Wed Apr 13 13:12:35 1994 Per Bothner (bothner@kalessin.cygnus.com)
9096 * decl.c (finish_decl): Don't mindlessly set TREE_USED for
9097 static consts any more (toplev.c has now been modified to
9098 not emit warnings if they are unused).
9100 Wed Apr 13 00:22:35 1994 Jason Merrill (jason@deneb.cygnus.com)
9102 * decl.c (grok_op_properties): If op new/delete get here with
9103 METHOD_TYPEs, do a revert_static_member_fn.
9105 * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
9106 * init.c (is_aggr_typedef): Don't look at
9107 IDENTIFIER_CLASS_TYPE_VALUE.
9108 (get_aggr_from_typedef): Ditto.
9109 (get_type_value): Ditto.
9110 * call.c (build_scoped_method_call): Don't rely on overloaded
9111 template names having IDENTIFIER_CLASS_VALUE set.
9113 * parse.y (component_decl_1, fn.def2): Revert rules for
9115 (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
9118 * decl.c (start_function): Only warn about `void main()' if pedantic
9119 || warn_return_type.
9121 Tue Apr 12 02:14:17 1994 Jason Merrill (jason@deneb.cygnus.com)
9123 Clean up overloading of the template name.
9124 * class.c (pushclass): overload the template name whenever pushing
9125 into the scope of a template class, not just if it is
9127 (popclass): Correspondingly.
9128 * search.c (push_class_decls): Don't overload_template_name.
9129 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
9130 DECL_CONTEXT on things.
9131 * parse.y (left_curly): Don't overload_template_name.
9132 * class.c (finish_struct): Don't undo_template_name_overload.
9134 * method.c (build_opfncall): Only pass one argument to global op
9137 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
9138 decide how many arguments to use for vec delete.
9140 * decl.c (grok_op_properties): Be consistent in modifying
9142 (grokdeclarator): Only complain about function decls with no return
9143 type if we're being pedantic.
9145 Mon Apr 11 00:10:53 1994 Jason Merrill (jason@deneb.cygnus.com)
9147 Add support for operator new [] and operator delete [].
9149 * tree.def: Add VEC_NEW_EXPR and VEC_DELETE_EXPR.
9150 * ptree.c (print_lang_type): Indicate vec new/delete.
9151 * parse.y: Support vec new/delete.
9152 * method.c (build_decl_overload): Deal with vec new/delete.
9153 (build_opfncall): Ditto.
9154 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
9155 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
9156 * init.c (init_init_processing): Set up BIVN and BIVD.
9157 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
9158 since it doesn't happen any more.
9159 (build_new): Support vec new. Always call something.
9160 (build_x_delete): Support vec delete.
9161 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
9162 and pass it to build_x_delete.
9163 * decl2.c (delete_sanity): Don't change behavior by whether or not
9164 the type has a destructor. Pass use_global_delete to
9166 (coerce_delete_type): Make sure that the type returned has a first
9167 argument of ptr_type_node.
9168 * decl.c (init_decl_processing): Also declare the global vec
9170 (grokdeclarator): Also force vec new/delete to be static.
9171 (grok_op_properties): Note presence of vec new/delete, and play with
9172 their args. If vec delete takes the optional size_t argument, set
9173 TYPE_VEC_DELETE_TAKES_SIZE.
9174 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
9175 checking for one delete or the other.
9176 (lang_type): gets_new and gets_delete are now two bits long. The
9177 low bit is for the non-array version. Lose gets_placed_new.
9178 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
9179 delete defined by this class wants to know how much space it is
9181 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
9182 add a header containing the number of elements in the vector; i.e.
9183 when the elements need to be destroyed or vec delete wants to know
9185 * class.c (finish_struct_methods): Also check for overloading vec
9187 * call.c (build_method_call): Also delete second argument for vec
9190 * decl.c (grokdeclarator): Correct complaints again.
9191 (grokdeclarator): Fix segfault on null declarator.
9192 (decls_match): Also accept redeclaration with no arguments if both
9193 declarations were in C context. Bash TREE_TYPE (newdecl) here.
9194 (duplicate_decls): Instead of here.
9196 * parse.y (nested_name_specifier_1): Lose rules for dealing with
9197 syntax errors nicely, since they break parsing of 'const i;'.
9199 * decl.c (lookup_name): if (got_scope == current_class_type)
9200 val = IDENTIFIER_CLASS_VALUE (name).
9202 * search.c (lookup_nested_tag): Look in enclosing classes, too.
9204 * spew.c (yylex): Only look one character ahead when checking for a
9207 * lex.c (check_newline): Read first nonwhite char before
9208 incrementing lineno.
9210 * decl.c (grokdeclarator): Don't claim that typedefs are variables
9213 * parse.y: Divide up uses of unqualified_id into
9214 notype_unqualified_id and unqualified_id, so that TYPENAME can be
9215 used as an identifier after an object.
9217 * class.c (push_nested_class): Don't push into non-class scope.
9219 * decl.c (grokdeclarator): If an identifier could be a type
9220 conversion operator, but has no associated type, it's not a type
9221 conversion operator.
9223 * pt.c (unify): Check for equality of constants better.
9225 * decl.c (grokdeclarator): Don't complain about access decls.
9227 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
9229 * decl.c (grokdeclarator): pedwarn about data definitions without
9232 * parse.y (datadef): Don't pedwarn about decls without types here,
9233 since that is valid for functions.
9234 (fn.def2, component_decl): Support constructors with declmods again.
9235 (nomods_initdecls): For decls without any mods, so that we don't try
9236 to get declspecs from some arbitrary $0.
9238 * search.c (lookup_field): Use cp_error.
9240 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
9241 here; it breaks destructors for non-aggr types.
9243 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
9244 a type being defined, like the comment says.
9245 If got_scope is not an aggregate, just return NULL_TREE.
9247 * pt.c (create_nested_upt): Kung's code for creating types nested
9248 within uninstantiated templates now lives here (it used to live in
9249 hack_more_ids). It needs to be expanded.
9251 * parse.y: Stop calling see_typename so much.
9253 * decl.c (lookup_name): Deal with TTPs and UPTs.
9255 * lex.c (real_yylex): Don't set looking_for_typename just because we
9257 (dont_see_typename): #if 0 out.
9259 * spew.c (yylex): Increment looking_for_typename if the next
9260 character is SCOPE, rather than setting it to 1; this way, the value
9261 from seeing an aggr specifier will not be lost. This kinda relies
9262 on looking_for_typename never being < 0, which is now true.
9264 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
9266 (named_class_head_sans_basetype): Accept template types, too. Oops.
9268 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
9270 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
9272 * parse.y: Lose START_DECLARATOR.
9274 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
9277 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
9278 A::foo' syntax. Catch invalid scopes better.
9280 * parse.y, lex.c: lose TYPENAME_COLON.
9282 * decl2.c (groktypefield): #if 0 out.
9284 * decl.c (lookup_name): If the type denoted by got_scope is
9285 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
9287 * class.c (push_nested_class): Don't try to push into
9290 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
9292 * Makefile.in (stamp-parse): Update count of conflicts to 33.
9294 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
9296 A saner implementation of nested types that treats template types
9297 no differently from non-template types. There are still some
9298 shortcomings of our system; most notably, it is difficult to look
9299 for a nested type that is hidden by another name, because of the way
9300 we keep track of hidden types. But this shouldn't be a problem for
9301 just about anyone. Perhaps lookup_field should be fixed up a bit.
9303 * spew.c: Moved handling of nested types/scoping from the lexer
9304 into the parser. Removed variable template_type_seen_before_scope.
9305 Removed functions frob_identifier, hack_more_ids, and various cruft
9306 that was #if 0'd out in the past, reducing the size of the file from
9307 1146 lines to 450 lines. We can't quite do away with spew.c yet,
9308 though; we still need it for do_aggr () and checking for SCOPE after
9309 the current identifier. And setting lastiddecl.
9311 * parse.y: Moved handling of nested types/scoping from the lexer
9312 into the parser, using a new global variable `got_scope'. Reduced
9313 the number of states by 53. Implemented all uses of explicit global
9314 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
9315 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
9316 scoped_typename. Added nonterminals nested_type,
9317 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
9318 nested_name_specifier, global_scope, overqualified_id, type_name.
9319 Changed many others. Added 9 new reduce/reduce conflicts, which are
9320 nested type parallels of 9 that were already in the grammar for
9321 non-nested types. Eight of the now 33 conflicts should be removed
9322 in the process of resolving the late binding between variable and
9325 * gxxint.texi (Parser): Update.
9327 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
9329 * lex.h: Add decl for got_scope.
9331 * lex.c (see_typename): Claim to be the lexer when calling
9334 * decl.c (lookup_name): When called from the lexer, look at
9335 got_scope and looking_at_typename; otherwise don't.
9337 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
9339 31th Cygnus<->FSF merge.
9341 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
9343 * decl2.c (mark_vtable_entries): Call this to mark all the
9344 entries in the vtable addressable.
9345 (finish_decl_parsing): Handle SCOPE_REFs.
9347 * decl.c (decls_match): Always call compparms with strict == 1.
9348 Handle the special case of C function redecl here.
9349 (duplicate_decls): Only keep the old type if the new decl takes no
9352 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
9354 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
9356 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
9359 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
9361 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
9362 ch-tree.h: Every place these functions were called, the result was
9363 immediately passed to expand_expr_stmt. Reduce redundancy by
9364 calling expand_expr_init *inside* these functions. These
9365 makes for a simpler interface, and we don't have to build
9366 compound expressions. Hence, rename these function to:
9367 expand_virtual_init and expand_vbase_vtables_init respectively.

9369 * init.c, cp-tree.h (expand_virtual_init): Make static.
9371 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
9372 rather than DECL_SAVED_INSNS before emitting inlines.

9381 (decls_match): Call compparms with a value of strict dependent on
9382 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
9384 * typeck.c (compparms): ... is only equivalent to non-promoting
9385 parms if we're not being strict.
9387 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
9389 * decl.c (init_decl_processing): if (flag_ansi || pedantic)

9404 to add delta field from vtable (there is none!).
9405 * decl.c: Add memptr_type as well as vtable_entry_type.
9406 If using thunks, the latter is just ptr_type_node.
9407 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
9408 * decl2.c (finish_vtable_vardecl): Handle thunks.

9422 * decl2.c (mark_inline_for_output): Do nothing if
9423 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
9424 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
9425 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.

9428 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
9430 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
9431 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
9432 instead. (The rationale is that these optimizations both break binary
9433 compatibility, but should become the default in a future release.)
9435 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
9437 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
9438 of a fndecl, as we might not be from that vfield.

9442 * class.c (add_virtual_function): fix bug for pure virtual, so
9443 that DECL_VINDEX of the dummy decl copied won't be error.

9448 * typeck.c (c_expand_return): Before checking that we're not
9449 returning the address of a local, make sure it's a VAR_DECL.
9450 (And don't worry about it being a TREE_LIST.)
9452 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
9454 * parse.y (YYDEBUG): Always define.
9455 * lex.c (YYDEBUG): Ditto.
9457 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)

9480 * call.c (build_method_call): When looking at global functions,
9481 be sure to use instance_ptr for the first argument, not some version
9482 of it that has been cast to a base class. Also do this before
9483 comparing candidates.

9516 * search.c (get_abstract_virtuals_1): New routine.
9518 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)

9562 * decl.c (pushdecl): If pushing a C-linkage function, only do a
9563 push_overloaded_decl.
9564 (duplicate_decls): Standard overloading does not shadow built-ins.

9597 parameters may be different.
9599 * call.c (build_method_call): Use brendan's candidate printing
9602 * decl.c (start_method): Methods defined in the class body are
9603 inline whether or not it's a template class.

9622 (start_function): Ditto.
9623 (push_overloaded_decl): Don't check for overloaded C functions.
9625 * *.c: Stop using DECL_OVERLOADED, it being archaic.
9626 TREE_OVERLOADED should probably go, too.
9628 Mon Mar 28 14:00:45 1994 Ron Guilmette (rfg@netcom.com)
9630 * typeck.c (comp_target_types): Call comp_target_parms with

9739 Tue Mar 22 12:44:54 1994 Jason Merrill (jason@deneb.cygnus.com)
9741 These patches implement handling of redefinition/redeclaration of
9744 * typeck.c (comptypes): Simplify. All TEMPLATE_TYPE_PARMs are
9745 considered compatible.
9747 * parse.y (template_def): Pass defn argument to end_template_decl.
9749 * pt.c (end_template_decl): Add defn argument. Check for
9750 redefinition. Simplify.
9752 * error.c (OB_UNPUT): New macro, to remove mistakes.
9753 (aggr_variety): Subroutine of dump_aggr_type.
9755 * decl.c (decls_match): Support templates.

9765 * error.c (dump_decl): Support class template decls.
9766 (dump_type): Don't adorn template type parms.
9768 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl

9775 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
9776 in FIELD context, when appropriate. Also,
9777 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
9778 Also, simplify check for bogus return specifiers.
9780 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
9782 * parse.y (after_type_declarator1): Expand type_quals.
9783 (notype_declarator1): Ditto.
9786 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
9788 * decl.c (grokdeclarator): Treat class-local typedefs like static
9789 members; i.e. 'typedef int f();' means that f is a function type,
9792 * parse.y (decl): Change direct_* back to *.
9793 (type_id): Change direct_abstract_declarator to absdcl.
9794 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.

9798 These two patches fix crashes on instantiating a template inside a
9799 function with C linkage or containing labels.
9801 * class.c (current_lang_stacksize): No longer static.
9803 * decl.c (struct saved_scope): Add lang_base, lang_stack,

9805 (push_to_top_level): Save them.
9806 (pop_from_top_level): Restore them.
9808 * gxxint.texi (Parser): Update.
9810 These two patches finish moving the task of expr/declarator
9811 ambiguity resolution from the lexer to the parser, and add one more
9812 r/r conflict. START_DECLARATOR can now be nuked.
9814 * parse.y (decl): Add "direct_" in typespec X rules.
9815 (direct_declarator): New nonterminal for
9816 direct_after_type_declarator and direct_notype_declarator.
9817 (direct_initdecls): Like initdecls, but uses direct_initdcl0.

9819 (named_parm): Add typespec direct_declarator rule.
9821 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
9823 These two patches disable some excessive cleverness on the part of
9824 g++; a non-class declaration always hides a class declaration in the
9825 same scope, and g++ was trying to unhide it depending on the
9826 enclosing expression.
9828 * spew.c (arbitrate_lookup): #if 0 out.
9830 * decl.c (lookup_name): Never call arbitrate_lookup.
9832 * parse.y (complex_notype_declarator1): Add '*'
9833 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
9835 * parse.y (complex_direct_notype_declarator): Restore id_scope
9836 see_typename TYPENAME rule, remove all other rules beginning with
9838 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
9840 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
9842 These changes fix the compiler's handling of the functional cast/
9843 object declaration ambiguities in section 6.8 of the ARM. They also
9844 add 11 reduce/reduce conflicts. Sigh.
9846 * parse.y: Add precedence decls for OPERATOR and '~'.
9847 (notype_unqualified_id): New nonterminal, encompasses all of the
9848 ANSI unqualified-id nonterminal except TYPENAMEs.
9849 (expr_or_declarator): New nonterminal to delay parsing of code like
9851 (primary): Use notype_unqualified_id.
9852 (decl): Add typespec initdecls ';' and typespec declarator ';'
9854 (initdcl0): Deal with the above.
9855 (complex_notype_declarator1): A notype_declarator that is not also
9856 an expr_or_declarator.
9857 (complex_direct_notype_declarator): A direct_notype_declarator that
9858 doesn't conflict with expr_or_declarator. Use
9859 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
9860 (functional_cast): New nonterminal, for the three functional cast
9861 rules. So that they can be moved after
9862 complex_direct_notype_declarator.
9863 (see_typename): Don't accept type_quals any more.
9865 * decl2.c (reparse_decl_as_expr): New function to deal with parse
9866 nodes for code like `int (*a)++;'.
9867 (reparse_decl_as_expr1): Recursive subroutine of the above.
9868 (finish_decl_parsing): New function to deal with parse nodes for
9869 code like `int (*a);'. See the difference?
9871 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
9873 These changes break binary compatibility in code with classes
9874 that use virtual bases.
9876 * search.c (dfs_get_vbase_types): Simplify and correct to make
9877 sure virtual bases are initialized in dfs ordering.
9878 * search.c (get_vbase_types): Simplify and make readable.
9880 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)
9882 * parse.y: s/ typename / type_id /g

9903 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
9905 * search.c (get_base_distance_recursive): Two binfos can only
9906 represent the same object if they are both via_virtual.
9908 * class.c (finish_base_struct): Check vbases for ambiguity, too.

9994 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
9995 so that it is like setHandler(&A::handlerFn). Cures an `invalid

10000 * gxxint.texi (Copying Objects): New section discussing default
10001 op= problems with virtual inheritance.

10024 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
10025 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid

10041 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
10042 than expanding it inline.

10044 (abs_or_notype_decl): Ditto.
10045 (absdcl): Lose empty rule.
10046 (conversion_declarator): New nonterminal for 'typename' of 'operator
10048 (operator_name): Use it instead of absdcl.
10050 * parse.y: Add precedence declarations for SCOPED_TYPENAME,
10052 (typed_declspecs): Accept typed_typespecs, rather than typespec
10053 directly. Add rules with reserved_typespecquals.
10054 (reserved_declspecs): Don't accept typespecqual_reserved at the
10055 beginning of the list. The typed_declspecs rule will deal with this
10057 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
10060 * parse.y (direct_notype_declarator,
10061 direct_after_type_declarator, direct_abstract_declarator): Split up
10062 the declarator1 nonterminals to match the draft standard and avoid
10064 (new_type_id, new_declarator, direct_new_declarator,

10078 (get_decl_list): Use it.
10079 (list_hash_lookup_or_cons): Ditto.
10081 * parse.y (typed_declspecs, declmods): It's not necessary to hash
10082 the declspecs on class_obstack, so don't. This way typed_typespecs
10083 can reduce to typed_declspecs.
10085 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
10087 * cvt.c (build_up_reference): If we aren't checking visibility,
10088 also allow base->derived conversions.
10090 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
10092 * typeck.c (build_c_cast): Remove bogus hack when converting

10104 a non-inline virtual function to control emitting of vtables.
10105 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
10106 * search.c (build_vbase_vtables_init): Don't assemble_external
10107 (yet) if flag_vtable_hack.

10110 Mon Feb 28 14:54:13 1994 Jason Merrill (jason@deneb.cygnus.com)
10112 * parse.y (component_decl): Don't include "typed_declspecs
10113 declarator ';'" speedup, since it breaks enums.
10115 Fri Feb 25 15:43:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
10117 * class.c (finish_struct): Minor optimization for building

10126 * lex.c (check_newline): #pragma interface can take a string
10127 argument, just like #pragma implementation. #pragma implementation
10128 checks for garbage on the line, line #pragma interface does. Main
10129 input files do not auto implement like named files, #pragma
10130 implementation must be used explicitly.
10132 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
10134 * parse.y (components): Handle list of one again.

10144 * Makefile.in (stamp-parse): Update expected conflict count.
10146 * parse.y (various): Replace "declmods declarator" with "declmods
10147 notype_declarator". The comment saying that "declmods declarator ';'"
10148 corresponds to "int i;" was wrong; it corresponds to "const i;".
10149 (component_decl): Add "typed_declspecs declarator ';'" rule; this
10150 *does* correspond to "int i;". Change "declmods components" to
10151 "declmods notype_components".
10152 (components): Don't deal with a list of one anymore.
10153 (notype_components): New nonterminal, corresponds to notype_declarator.
10154 ({after_,no}type_component_decl{,0}): More new nonterminals.
10155 ({after_,no}type_declarator): Fold in START_DECLARATOR token.
10156 Eliminates four reduce/reduce conflicts.

10161 (nonnull_exprlist): Depend on nontrival_exprlist.
10162 Eliminates four reduce/reduce conflicts.
10164 (named_class_head): Move intermediate code block into separate
10165 nonterminal so that we can stick %prec EMPTY on it.
10167 Add more %prec EMPTY's to eliminate remaining shift/reduce
10170 (after_type_declarator): Add maybe_raises to fndecl rules.
10171 (after_type_declarator_no_typename): Remove.

10179 (TYPE_BINFO (type)) if we care about the path.
10181 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
10184 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>
10186 * Makefile.in (mostlyclean): lex.c is a source file, don't

10191 * parse.y: Eliminate 20 shift/reduce conflicts.
10193 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
10195 * pt.c (type_unification): Add subr argument; if set, it means
10196 that we are calling ourselves recursively, so a partial match is OK.
10197 (unify): Support pointers to methods and functions.
10198 (tsubst): Support method pointers.
10199 * decl.c (build_ptrmemfunc_type): No longer static, so that
10200 tsubst can get at it.
10202 * init.c (is_aggr_typedef): Pretend template type parms are
10204 * decl2.c (build_push_scope): If cname refers to a template type
10205 parm, just grin and nod.
10207 * call.c (build_overload_call_real): Pass subr argument to
10209 * pt.c (do_function_instantiation): Ditto.
10210 * class.c (instantiate_type): Ditto.

10216 If ambiguous, return error_mark_node.
10218 * init.c (build_new): Put back some necessary code.
10220 Thu Feb 17 15:39:47 1994 Jason Merrill (jason@deneb.cygnus.com)

10226 (get_base_distance_recursive): Find the path to the via_virtual base
10227 that provides the most access.
10228 (get_base_distance): Ditto.
10230 * parse.y (explicit_instantiation): Syntax is 'template class
10231 A<int>', not 'template A<int>'.
10233 * typeck.c (convert_for_initialization): Remove bogus warning.
10235 * parse.y (datadef): Revert patch of Oct 27.
10237 Thu Feb 17 15:12:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
10239 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,
10240 rather than integer_type_node. Does wonders for the Alpha.

10244 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type

10249 * cvt.c (convert_to_reference): If converting via constructor
10250 on local level, go back to build_cplus_new approach.
10252 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
10253 to error_mark_node to prevent expand_expr from building a cleanup
10256 * lex.c (default_assign_ref_body): Return *this from the memcpy
10259 * decl.c (grok_reference_init): Just return if called with
10260 error_mark_node, don't worry about initializing non-const reference
10263 * cvt.c (convert_to_reference): Do the right thing for
10264 non-aggregate reference conversions, pedwarn when generating a
10265 non-const reference to a temporary.
10267 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
10268 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
10271 Tue Feb 15 19:47:19 1994 Jason Merrill (jason@deneb.cygnus.com)
10273 * decl.c (grok_reference_init): Pawn off a lot of the work on
10274 convert_to_reference. Generally do the right thing.
10276 * cvt.c (convert_to_reference): Conform to the initial comment;
10277 i.e. don't create temps if decl != error_mark_node. Handle
10278 cleanups better for temps that do get created. Don't pretend
10279 that we can use an 'A' to initialize a 'const double &' just by
10280 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
10282 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

10293 * decl.c (pushdecl): Define decl in correct binding_level
10294 (which isn't always the inner_binding_level).
10296 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
10297 It's ugly, and I don't think it's the right thing to do.
10299 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
10300 Remove NEW_CLASS_SCOPING, assuming it is always 1.
10301 * decl.c (pop_decl_level): Removed; manually inlined.
10303 Sun Feb 13 19:04:56 1994 Jason Merrill (jason@deneb.cygnus.com)
10305 * class.h (candidate): Add basetypes field.
10307 * call.c (build_method_call): Do access checking after choosing a

10316 of a base class if a local field has the same name.
10318 * error.c (dump_type_prefix): Output basetype for METHOD_TYPEs.

10322 * cp-tree.h (DESTRUCTOR_NAME_P): do not confuse AUTO_TEMP names
10323 with destructor names when either NO_DOLLAR_IN_LABEL or
10324 NO_DOT_IN_LABEL are not defined.
10326 Now `template <class T, T f(T&), const T*> class A {...}' works.
10328 * pt.c (grok_template_type): substitute template parm types
10329 with actual types in complex type as well.
10330 (coerce_template_parms): update the grok_template_type ()
10333 * pt.c (tsubst): Traverse method list using DECL_CHAIN.
10335 * decl.c (grok_op_properties): Allow operator++/-- to have
10338 * typeck2.c (store_init_value): Don't abort when called to
10339 initialize a type that needs constructing with a CONSTRUCTOR.
10341 * init.c (expand_aggr_init_1, CONSTRUCTOR case): If
10342 store_init_value fails, build and expand an INIT_EXPR. If
10343 store_init_value succeeds, call expand_decl_init.
10345 Fri Feb 11 02:49:23 1994 Mike Stump <mrs@cygnus.com>
10347 * class.c (build_vbase_path): Use complete_type_p instead of
10348 resolves_to_fixed_type_p to determine if the virtual bases are in
10349 their right place for the type of expr. Cures problem of thinking a
10350 virtual base class is one place, when it is in fact someplace else.
10352 Fri Feb 11 00:26:46 1994 Mike Stump <mrs@cygnus.com>
10354 * init.c (resolve_offset_ref): Make sure we first convert to
10355 intermediate type, if given, when dealing with members off `this'.
10356 Solves an incorrrect `type `foo' is not a base type for type
10357 `multiple'' when it is infact, a base type.
10359 Thu Feb 10 21:49:35 1994 Mike Stump <mrs@cygnus.com>
10361 * class.c (modify_other_vtable_entries): Use get_binfo, instead
10362 of binfo_value. Solves problem with compiler giving a `base class
10363 `B' ambiguous in binfo_value (compiler error)' on complex MI
10364 herarchies, when a virtual function is first defied in a virtual
10367 Thu Feb 10 17:19:32 1994 Mike Stump <mrs@cygnus.com>
10369 * class.c (build_vbase_path): Don't complain about ambiguous
10370 intermediate conversion when converting down to a virtual base
10371 class, even if they might seem to be ambiguous.
10373 Thu Feb 10 12:18:26 1994 Jason Merrill (jason@deneb.cygnus.com)
10375 * typeck2.c (build_functional_cast): #if 0 out constructor

10379 non-default constructors in derived class with no constructors.
10381 * decl.c (grokdeclarator): Fix detection of virtual new/delete.

11142 to check if two fndecls are `the same'. Sometimes this routine can
11143 modify the main vtable, and normal should be 1, in that case, so use
11144 is_normal() to determine if this is the main vtable for the class.

11146 care of them elsewhere.
11147 * cp-class.c (modify_vtable_entries): If we have already updated the
11148 vtable with the new virtual, don't do it again.

11189 * cp-decl2.c (explicit_warn_return_type): Deleted variable.
11190 (lang_decode_option): Set warn_return_type, not explicit_*, for

11194 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
11195 (finish_function): Also complain about no return in a non-void fn if
11196 we're being pedantic (don't rely on use of -Wreturn-type).

11253 * cp-class.c (finish_base_struct): Set cant_synth_* correctly.
11254 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
11255 properly with the case where a class contains an object of an
11256 ambiguous base class which has a protected op=. Should be fixed
11257 when the access control code gets overhauled.
11258 (finish_struct_methods): Set TYPE_HAS_NONPUBLIC_* correctly.
11260 Thu Dec 16 12:17:06 1993 Brendan Kehoe (brendan@lisa.cygnus.com)

11416 marker for the end of the list of candidates.
11418 * cp-cvt.c (convert_to_aggr): Make sure to always set H_LEN.

11583 (build_method_call): When we had some candidates, but didn't get a

11587 clear out ever_seen, so we can accurately count the number of
