1084 * cp-tree.h (expand_start_early_try_stmts): Declare it.
1085 * parse.y (function_try_block): Use it, instead of doing it here, as
1086 we don't want to include rtl.h here, as that conflicts with RETURN

1091 * lex.c (reinit_parse_for_block): Support saving inline
1092 function-try-blocks, uses peekyylex.
1093 * parse.y (eat_saved_input): New rule, permit the parser to see that
1094 END_OF_SAVED_INPUT is ok, as it can see this when parsing the
1095 handlers of a function-try-block.
1097 (component_decl): Make sure TRY and RETURN can come after fn.def2.
1098 * spew.c (peekyylex): New routine to peek at what will come next.

1118 to include function_try_block syntax.

1197 Wed Aug 30 15:24:38 1995 Stephen L. Favor (sfavor@tigger.intecom.com)
1199 * except.c (expand_builtin_throw): Moved gen_label_rtx calls beyond
1200 the store_parm_decls call which does initialization in the emit_*
1201 code concerning label numbering.
1203 Thu Aug 31 09:01:07 1995 Mike Stump <mrs@cygnus.com>
1205 * except.c (expand_internal_throw): Let the frontend be responsible
1206 for managing all frontend EH parameters, the backend routine only
1207 needs to deal with backend values. type and value are no longer

1226 value are now trees.
1228 Mon Aug 28 17:57:45 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1230 Fix the attribute handling to make sure they get noted before we
1231 create the function's RTL, in case they can affect that.

1280 Tue Aug 22 17:20:07 1995 Per Bothner <bothner@kalessin.cygnus.com>
1282 * decl2.c (flag_new_for_scope): Add a new mode that follows ANSI
1283 for-scoping, but supports (and warns about) old programs.
1284 Make the new mode (with value 1) the default.
1285 (lang_f_options): The on-value for flag_new_for_scope is now 2.
1286 * cp-tree.h (DECL_DEAD_FOR_LOCAL, DECL_ERROR_REPORTED): New macros
1287 (DECL_SHADOWED_FOR_VAR): Likewise.
1288 * decl.c (struct binding_level): New fields dead_vars_from_for

1297 Mon Aug 21 10:28:31 1995 Jason Merrill <jason@deneb.cygnus.com>
1299 * decl2.c (import_export_inline): Class interface hackery does not
1300 apply to synthesized methods.
1302 Sun Aug 20 16:29:00 1995 Mike Stump <mrs@cygnus.com>
1304 * search.c (virtual_context): Find the right context more often.
1305 Solves a `recoverable compiler error, fixups for virtual function'
1308 Sun Aug 20 13:53:24 1995 Mike Stump <mrs@cygnus.com>
1310 * except.c (expand_start_all_catch): Ensure that we always transfer
1311 control to the right EH handler, by rethrowing the end label on the
1312 region, instead of hoping we are nested and falling through.
1313 (expand_leftover_cleanups): Ditto.
1314 (end_protect): Since we now rethrow the end label, put a
1315 nop after it, so that outer regions are recognized.
1316 * init.c (build_vec_delete_1): New routine to handle most of vector
1317 deleting, all code moved here from build_vec_delete.
1318 (build_array_eh_cleanup): Use build_vec_delete_1 to do all the real

1321 EH region to handle it.
1322 (build_vec_delete): Move lots of code to build_vec_delete_1, use
1323 build_vec_delete_1 to do the grunt work.
1325 Sat Aug 19 14:25:33 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1327 Handle decl attributes properly for function definitions without
1328 previous attribute-loaded declarations.
1329 * decl.c (start_function): New arg ATTRS. Add a call to
1330 cplus_decl_attributes with it before we create the RTL.
1331 * cp-tree.h (start_function): Update prototype.
1332 * parse.y (fn.def1): Pass ATTRS into start_function instead of

1335 * decl2.c (finish_file): Pass NULL_TREE as fourth arg to
1337 * method.c (synthesize_method): Likewise.
1338 * except.c (expand_builtin_throw): Likewise for start on __throw.
1340 Sat Aug 19 13:36:08 1995 Mike Stump <mrs@cygnus.com>
1342 * class.c (set_rtti_entry): Turn on -fvtable-thunk -frtti support.
1343 This changes -fvtable-thunks vtable layout, so a recompile will be
1344 necessary, if you use -fvtable-thunks.
1345 (get_vtable_entry): Use n, instead of i to be consistent with the
1346 rest of the compiler.
1347 (get_vtable_entry_n): Ditto.

1362 * cp-tree.h (skip_rtti_stuff): New routine, declare it.
1363 * gc.c (build_headof): Support -fvtable-thunk and -frtti together.
1364 (build_typeid): Ditto.

1373 * decl.c (start_function): Clear ctor_label and dtor_label.

1377 Tue Aug 15 19:21:54 1995 Jason Merrill <jason@phydeaux.cygnus.com>

1380 can be used for class template definitions, as well.
1381 (finish_struct_1): New function with the rest of the code.
1383 Tue Aug 15 09:46:16 1995 Mike Stump <mrs@cygnus.com>
1385 * class.c (prepare_fresh_vtable): On second though, always build the
1386 offset (see Aug 10 change), unless -fvtable-thunks is given. It
1387 does this by calling the new routine set_rtti_entry.
1388 (finish_struct): Ditto.
1389 (set_rtti_entry): New routine to update the rtti information at the
1390 start of the vtable.
1392 Mon Aug 14 12:21:22 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1394 * error.c (dump_decl, case IDENTIFIER_NODE): Only work on a dtor
1395 if it's declared in the C++ language spec.
1396 (dump_function_decl): Likewise.
1397 (dump_function_name): Likewise.
1398 (ident_fndecl): Make sure we got something back from lookup_name.
1399 * decl.c (start_function): Likewise.
1401 Fri Aug 11 16:52:15 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1403 * call.c (build_method_call): Don't call build_new when calling a
1404 constructor without an instance.
1406 Thu Aug 10 20:00:17 1995 Mike Stump <mrs@cygnus.com>
1408 * class.c (prepare_fresh_vtable): Always build the offset to the
1409 complete object, as it doesn't cost much. This allows dynamic_cast
1410 to void * to work when -frtti isn't given.
1411 (finish_struct): Ditto.
1413 Thu Aug 10 16:31:28 1995 Mike Stump <mrs@cygnus.com>
1415 * except.c (build_eh_type): Split out some functionality to new
1416 routine named build_eh_type_type.
1417 (build_eh_type_type): New routine.
1418 (expand_start_catch_block): Use build_eh_type_type, as we never want
1419 the dynamic type of the catch parameter, just the static type.
1420 Fixes core dumps when -frtti is used and one catchs pointers to
1423 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
1425 * except.c (expand_builtin_throw): Since we now use normal calling
1426 conventions for __throw, we have to remove the first layer off the
1427 stack, so that the next context we search for handlers is the outer
1428 context instead of the context that had the call to __throw, if we
1429 don't immediately find the desired context.
1431 Tue Aug 8 17:44:23 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1433 * tree.c (cp_expand_decl_cleanup): Returns int, not tree.
1434 * cp-tree.h: Update.

1446 (throw_label): Removed.
1447 (expand_builtin_throw): Changed so that EH parameters are passed by
1448 normal function call conventions. Completes Aug 4th work.

1452 * cp-tree.h (expand_builtin_throw): Declare it.
1453 * decl2.c (finish_file): Call expand_builtin_throw.
1454 * except.c (make_first_label): Remove.
1455 (init_exception_processing): Don't use a LABEL_REF for throw_label,
1456 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
1457 other functions that don't really appear in those functions. This
1458 solves a problem where cc1plus consumed exponential amounts of
1459 memory when -Wall was used.
1460 (expand_end_all_catch, expand_leftover_cleanups,
1461 expand_end_catch_block, expand_throw): Change all uses of
1462 throw_label to match new style.
1463 (do_unwind): Rename parameter to inner_throw_label, as it is now
1464 different from throw_label. Also, assume that our caller will wrap
1465 the passed label with a LABEL_REF, if needed.
1466 (expand_builtin_throw): Make external, change so that the generated
1467 throw is now a real function.
1468 (expand_exception_blocks): Never generate throw code inside another
1471 Fri Aug 4 12:20:02 1995 Mike Stump <mrs@cygnus.com>
1473 * decl.c (grokdeclarator): Move checking of mutable const objects
1474 and mutable static objects down, as we might decide during parsing
1475 to unset staticp or constp (for example, when const is part of the
1476 object being pointed to).
1478 Thu Aug 3 17:13:43 1995 Mike Stump <mrs@cygnus.com>
1480 * except.c (output_exception_table_entry): Enhance portability to
1482 (emit_exception_table): Ditto.

1502 exceptStack, exceptstack, push_except_stmts, pop_except_stmts,
1503 new_except_stack, push_last_insn, pop_last_insn, insn_save_node and
1504 InsnSave. Also, numerous speed improvements, and correctness
1505 improvements. Double faulting in all situations should now be
1507 (expand_start_all_catch): Instead of having many terminate protected
1508 regions, just have one.
1509 (expand_start_catch_block): No longer have to protect
1510 false_label_rtx, as it isn't used for EH region marking.
1511 (expand_end_catch_block): Expand out EH cleanups here by using
1512 expand_leftover_cleanups.
1513 (expand_end_all_catch): Use sequences instead of playing with insn
1515 (expand_exception_blocks): Ditto. Also protect all catch clauses
1516 with one terminate region.
1518 Mon Jul 31 13:24:30 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1520 * method.c (report_type_mismatch): Don't talk about an object
1521 parameter for non-methods.

3817 * parse.y (do_xref): Lose.
3818 (named_class_head): If we see 'class foo:' we know it's a

3823 * decl.c (duplicate_decls): Restore check for qualifier
3824 disagreement for non-functions.

3881 initializers are done as tdecls are initialized in the global
3882 initializer. Also Pick up any new tdecls or vtables needed by
3883 synthesized methods.
3885 * class.c (finish_struct): Simplify. We have to do rtti scanning at
3886 end, so we might as well do all of it there.

3890 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

3900 * decl2.c (finish_file): Call finish_prevtable_vardecl.
3901 * gc.c (build_generic_desc): Allow it to be called when not at the

3905 * class.c (finish_struct): Don't decide on tdecls here, as we have
3906 to wait until the end of the file in general to decide whether or

3940 * decl2.c (finish_vtable_vardecl): Now set the
3941 interface/implementation of vtables on the first virtual function,
3942 if one exists, otherwise we use the old method. This is a major win
3943 in terms of cutting down the size of objects and executables in
3944 terms of text space and data space. Now most of the savings that
3945 #pragma interface/implementation gives is automatic in a fair number

3967 unset it when we're done. Turn all 'return's into 'goto skipline'.

3969 character we read before checking for a sysv or target pragma.
3970 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.

4007 * typeck.c (convert_for_assignment): Initialize variable before use.

4131 they have the same precision.
4133 * decl.c (grokparms): Call convert_for_initialization to check
4136 * init.c (build_new): void_type_node has a size (of 0).

7859 notype_unqualified_id and unqualified_id, so that TYPENAME can be
7860 used as an identifier after an object.
7862 * class.c (push_nested_class): Don't push into non-class scope.
7864 * decl.c (grokdeclarator): If an identifier could be a type
7865 conversion operator, but has no associated type, it's not a type
7866 conversion operator.
7868 * pt.c (unify): Check for equality of constants better.
7870 * decl.c (grokdeclarator): Don't complain about access decls.
7872 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
7874 * decl.c (grokdeclarator): pedwarn about data definitions without
7877 * parse.y (datadef): Don't pedwarn about decls without types here,
7878 since that is valid for functions.
7879 (fn.def2, component_decl): Support constructors with declmods again.
7880 (nomods_initdecls): For decls without any mods, so that we don't try
7881 to get declspecs from some arbitrary $0.
7883 * search.c (lookup_field): Use cp_error.
7885 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
7886 here; it breaks destructors for non-aggr types.
7888 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
7889 a type being defined, like the comment says.
7890 If got_scope is not an aggregate, just return NULL_TREE.
7892 * pt.c (create_nested_upt): Kung's code for creating types nested
7893 within uninstantiated templates now lives here (it used to live in
7894 hack_more_ids). It needs to be expanded.
7896 * parse.y: Stop calling see_typename so much.
7898 * decl.c (lookup_name): Deal with TTPs and UPTs.
7900 * lex.c (real_yylex): Don't set looking_for_typename just because we
7902 (dont_see_typename): #if 0 out.
7904 * spew.c (yylex): Increment looking_for_typename if the next
7905 character is SCOPE, rather than setting it to 1; this way, the value
7906 from seeing an aggr specifier will not be lost. This kinda relies
7907 on looking_for_typename never being < 0, which is now true.
7909 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
7911 (named_class_head_sans_basetype): Accept template types, too. Oops.
7913 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7915 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
7917 * parse.y: Lose START_DECLARATOR.
7919 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
7922 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
7923 A::foo' syntax. Catch invalid scopes better.
7925 * parse.y, lex.c: lose TYPENAME_COLON.
7927 * decl2.c (groktypefield): #if 0 out.
7929 * decl.c (lookup_name): If the type denoted by got_scope is
7930 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
7932 * class.c (push_nested_class): Don't try to push into
7935 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7937 * Makefile.in (stamp-parse): Update count of conflicts to 33.
7939 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7941 A saner implementation of nested types that treats template types
7942 no differently from non-template types. There are still some
7943 shortcomings of our system; most notably, it is difficult to look
7944 for a nested type that is hidden by another name, because of the way
7945 we keep track of hidden types. But this shouldn't be a problem for
7946 just about anyone. Perhaps lookup_field should be fixed up a bit.
7948 * spew.c: Moved handling of nested types/scoping from the lexer
7949 into the parser. Removed variable template_type_seen_before_scope.
7950 Removed functions frob_identifier, hack_more_ids, and various cruft
7951 that was #if 0'd out in the past, reducing the size of the file from
7952 1146 lines to 450 lines. We can't quite do away with spew.c yet,
7953 though; we still need it for do_aggr () and checking for SCOPE after
7954 the current identifier. And setting lastiddecl.
7956 * parse.y: Moved handling of nested types/scoping from the lexer
7957 into the parser, using a new global variable `got_scope'. Reduced
7958 the number of states by 53. Implemented all uses of explicit global
7959 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
7960 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
7961 scoped_typename. Added nonterminals nested_type,
7962 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
7963 nested_name_specifier, global_scope, overqualified_id, type_name.
7964 Changed many others. Added 9 new reduce/reduce conflicts, which are
7965 nested type parallels of 9 that were already in the grammar for
7966 non-nested types. Eight of the now 33 conflicts should be removed
7967 in the process of resolving the late binding between variable and
7970 * gxxint.texi (Parser): Update.
7972 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
7974 * lex.h: Add decl for got_scope.
7976 * lex.c (see_typename): Claim to be the lexer when calling
7979 * decl.c (lookup_name): When called from the lexer, look at
7980 got_scope and looking_at_typename; otherwise don't.
7982 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
7984 31th Cygnus<->FSF merge.
7986 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7988 * decl2.c (mark_vtable_entries): Call this to mark all the
7989 entries in the vtable addressable.
7990 (finish_decl_parsing): Handle SCOPE_REFs.
7992 * decl.c (decls_match): Always call compparms with strict == 1.
7993 Handle the special case of C function redecl here.
7994 (duplicate_decls): Only keep the old type if the new decl takes no
7997 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
7999 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
8001 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
8004 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
8006 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
8007 ch-tree.h: Every place these functions were called, the result was
8008 immediately passed to expand_expr_stmt. Reduce redundancy by
8009 calling expand_expr_init *inside* these functions. These
8010 makes for a simpler interface, and we don't have to build
8011 compound expressions. Hence, rename these function to:
8012 expand_virtual_init and expand_vbase_vtables_init respectively.
8013 * init.c, decl.c: Change callers of these functions.
8014 * init.c, cp-tree.h (expand_virtual_init): Make static.
8016 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
8017 rather than DECL_SAVED_INSNS before emitting inlines.

8021 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
8023 * decl.c (duplicate_decls): If this is a new declaration of an
8024 extern "C" function, keep the type (for the argtypes).
8025 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
8026 (decls_match): Call compparms with a value of strict dependent on
8027 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
8029 * typeck.c (compparms): ... is only equivalent to non-promoting
8030 parms if we're not being strict.
8032 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
8034 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
8035 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
8037 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

8046 * cp-tree.h (memptr_type): New variable.
8047 * class.c (build_vtable_entry): Build thunk if necessary.
8048 * class.c (build_vfn_ref): If using thunks, don't need
8049 to add delta field from vtable (there is none!).
8050 * decl.c: Add memptr_type as well as vtable_entry_type.
8051 If using thunks, the latter is just ptr_type_node.
8052 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
8053 * decl2.c (finish_vtable_vardecl): Handle thunks.
8054 * expr.c (cplus_expand_expr): Support THUNK_DECL.
8056 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
8057 * decl.c (start_function): Set current_extern_inline based on
8058 DECL_THIS_EXTERN, not TREE_PUBLIC.
8059 * decl.c (finish_function): Call mark_inline_for_output if needed,
8061 Improve intelligence about when to emit inlines.
8062 * cp-tree.h (lang_decl_flags): New field saved_inline.

8067 * decl2.c (mark_inline_for_output): Do nothing if
8068 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
8069 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
8070 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
8071 * decl2.c (finish_file): Writing out inlines later, so we can
8072 also handle the ones needed for vtbales.
8073 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
8075 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
8076 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
8077 instead. (The rationale is that these optimizations both break binary
8078 compatibility, but should become the default in a future release.)
8080 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
8082 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
8083 of a fndecl, as we might not be from that vfield.
8085 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
8087 * class.c (add_virtual_function): fix bug for pure virtual, so
8088 that DECL_VINDEX of the dummy decl copied won't be error.
8089 (see also Apr 4 change)
8091 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
8093 * typeck.c (c_expand_return): Before checking that we're not
8094 returning the address of a local, make sure it's a VAR_DECL.
8095 (And don't worry about it being a TREE_LIST.)
8097 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8099 * parse.y (YYDEBUG): Always define.
8100 * lex.c (YYDEBUG): Ditto.
8102 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
8104 * class.c (finish_struct): backup out the change below, put the
8105 new change for the same purpose. The change below breaks code.
8107 * class.c (finish_struct): if pure virtual, copy node and make
8108 RTL point to abort, then put in virtual table.
8109 * decl2.c (grok_function_iit): reinstate Mar 31 change.
8111 Sat Apr 2 03:12:58 1994 Jason Merrill (jason@deneb.cygnus.com)
8113 * init.c (build_new): pedwarn about newing const and volatile
8116 * tree.c (get_identifier_list): Only do the special handling
8117 thing if we're dealing with the main variant of the record type.
8119 * cvt.c (convert_to_reference): When converting between
8120 compatible reference types, use the pointer conversion machinery.
8121 Don't just blindly overwrite the old type.
8123 Fri Apr 1 17:14:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8125 * call.c (build_method_call): When looking at global functions,
8126 be sure to use instance_ptr for the first argument, not some version
8127 of it that has been cast to a base class. Also do this before
8128 comparing candidates.

8132 * call.c (build_method_call): Constructors can be called for

8160 * search.c (get_abstract_virtuals): Reimplement.
8161 * search.c (get_abstract_virtuals_1): New routine.
8163 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)

8194 base class member should be called in some MI situations.
8196 * search.c (make_binfo): Use more the more specialized base

8238 when warning about re-friending.
8240 * pt.c (tsubst): Use comptypes rather than == to compare the
8241 types of the method as declared and as defined, since default
8242 parameters may be different.
8244 * call.c (build_method_call): Use brendan's candidate printing
8247 * decl.c (start_method): Methods defined in the class body are
8248 inline whether or not it's a template class.

8267 (start_function): Ditto.
8268 (push_overloaded_decl): Don't check for overloaded C functions.
8270 * *.c: Stop using DECL_OVERLOADED, it being archaic.

8376 * typeck.c (build_ptrmemfunc): Revamp to handle casting better, also
8377 get vtable pointer out of right subobject.
8379 Tue Mar 22 17:56:48 1994 Mike Stump <mrs@cygnus.com>
8381 * search.c (get_binfo): Return NULL instead of aborting, when
8382 passed a UNION_TYPE.
8384 Tue Mar 22 12:44:54 1994 Jason Merrill (jason@deneb.cygnus.com)
8386 These patches implement handling of redefinition/redeclaration of
8389 * typeck.c (comptypes): Simplify. All TEMPLATE_TYPE_PARMs are
8390 considered compatible.
8392 * parse.y (template_def): Pass defn argument to end_template_decl.
8394 * pt.c (end_template_decl): Add defn argument. Check for
8395 redefinition. Simplify.
8397 * error.c (OB_UNPUT): New macro, to remove mistakes.
8398 (aggr_variety): Subroutine of dump_aggr_type.
8400 * decl.c (decls_match): Support templates.
8401 (duplicate_decls): No longer static. Don't try to lay out template
8403 (pushdecl): Simplify.
8405 * cp-tree.h (DECL_TEMPLATE_MEMBERS): Use DECL_SIZE instead of
8408 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
8410 * error.c (dump_decl): Support class template decls.
8411 (dump_type): Don't adorn template type parms.
8413 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl
8414 if it was a definition.
8415 (redeclaration_error_message): Do the cp_error thang, and reject
8416 redefinition of templates.
8418 Mon Mar 21 19:36:06 1994 Per Bothner (bothner@kalessin.cygnus.com)
8420 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
8421 in FIELD context, when appropriate. Also,
8422 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
8423 Also, simplify check for bogus return specifiers.
8425 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
8427 * parse.y (after_type_declarator1): Expand type_quals.
8428 (notype_declarator1): Ditto.
8431 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
8433 * decl.c (grokdeclarator): Treat class-local typedefs like static
8434 members; i.e. 'typedef int f();' means that f is a function type,
8437 * parse.y (decl): Change direct_* back to *.
8438 (type_id): Change direct_abstract_declarator to absdcl.
8439 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.
8441 Fri Mar 18 12:47:59 1994 Jason Merrill (jason@deneb.cygnus.com)
8443 These two patches fix crashes on instantiating a template inside a
8444 function with C linkage or containing labels.
8446 * class.c (current_lang_stacksize): No longer static.
8448 * decl.c (struct saved_scope): Add lang_base, lang_stack,
8449 lang_name, lang_stacksize, and named_labels.
8450 (push_to_top_level): Save them.
8451 (pop_from_top_level): Restore them.
8453 * gxxint.texi (Parser): Update.
8455 These two patches finish moving the task of expr/declarator
8456 ambiguity resolution from the lexer to the parser, and add one more
8457 r/r conflict. START_DECLARATOR can now be nuked.
8459 * parse.y (decl): Add "direct_" in typespec X rules.
8460 (direct_declarator): New nonterminal for
8461 direct_after_type_declarator and direct_notype_declarator.
8462 (direct_initdecls): Like initdecls, but uses direct_initdcl0.

8464 (named_parm): Add typespec direct_declarator rule.
8466 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
8468 These two patches disable some excessive cleverness on the part of
8469 g++; a non-class declaration always hides a class declaration in the
8470 same scope, and g++ was trying to unhide it depending on the
8471 enclosing expression.
8473 * spew.c (arbitrate_lookup): #if 0 out.
8475 * decl.c (lookup_name): Never call arbitrate_lookup.
8477 * parse.y (complex_notype_declarator1): Add '*'
8478 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
8480 * parse.y (complex_direct_notype_declarator): Restore id_scope
8481 see_typename TYPENAME rule, remove all other rules beginning with
8483 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
8485 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
8487 These changes fix the compiler's handling of the functional cast/
8488 object declaration ambiguities in section 6.8 of the ARM. They also
8489 add 11 reduce/reduce conflicts. Sigh.
8491 * parse.y: Add precedence decls for OPERATOR and '~'.
8492 (notype_unqualified_id): New nonterminal, encompasses all of the
8493 ANSI unqualified-id nonterminal except TYPENAMEs.
8494 (expr_or_declarator): New nonterminal to delay parsing of code like
8496 (primary): Use notype_unqualified_id.

8499 (initdcl0): Deal with the above.
8500 (complex_notype_declarator1): A notype_declarator that is not also
8501 an expr_or_declarator.
8502 (complex_direct_notype_declarator): A direct_notype_declarator that
8503 doesn't conflict with expr_or_declarator. Use
8504 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
8505 (functional_cast): New nonterminal, for the three functional cast
8506 rules. So that they can be moved after
8507 complex_direct_notype_declarator.
8508 (see_typename): Don't accept type_quals any more.
8510 * decl2.c (reparse_decl_as_expr): New function to deal with parse
8511 nodes for code like `int (*a)++;'.
8512 (reparse_decl_as_expr1): Recursive subroutine of the above.
8513 (finish_decl_parsing): New function to deal with parse nodes for
8514 code like `int (*a);'. See the difference?
8516 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
8518 These changes break binary compatibility in code with classes
8519 that use virtual bases.
8521 * search.c (dfs_get_vbase_types): Simplify and correct to make
8522 sure virtual bases are initialized in dfs ordering.
8523 * search.c (get_vbase_types): Simplify and make readable.
8525 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)
8527 * parse.y: s/ typename / type_id /g
8529 Wed Mar 16 17:42:52 1994 Kung Hsu (kung@mexican.cygnus.com)
8531 * parse.y (typespec): add SCOPE TYPENAME for global scoped
8534 * decl.c (complete_array_type): fix a bug that in -pendantic
8535 mode even there's no initializer, it will continue to build
8538 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
8540 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
8541 all of the scoped PTYPENAME rules.
8543 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
8545 * init.c (build_offset_ref): The value of A::typedef_name is
8546 always the TYPE_DECL, and never an error.
8548 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8550 * search.c (get_base_distance_recursive): Two binfos can only
8551 represent the same object if they are both via_virtual.
8553 * class.c (finish_base_struct): Check vbases for ambiguity, too.
8555 * search.c (get_vbase_types): Accept binfo argument, too.
8557 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
8559 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
8560 initializer also, because back-end requires it.
8562 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
8564 * error.c (dump_expr): Support member functions (which show up as
8567 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>
8569 * init.c (build_new): Set the return type of multidimensional
8572 Fri Mar 11 15:35:39 1994 Kung Hsu (kung@mexican.cygnus.com)
8574 * call.c (build_method_call): if basetype not equal to type
8575 of the instance, use the type of the instance in building
8578 Thu Mar 10 17:07:10 1994 Kung Hsu (kung@mexican.cygnus.com)
8580 * parse.y (direct_notype_declarator): add push_nested_type for
8581 'template_type SCOPED_NAME' rule.
8583 Tue Mar 8 00:19:58 1994 Jason Merrill (jason@deneb.cygnus.com)
8585 * parse.y (parm): Add typed_declspec1 {absdcl, epsilon} rules.
8587 Sat Mar 5 04:47:48 1994 Jason Merrill (jason@deneb.cygnus.com)
8589 * parse.y (regcast_or_absdcl): New nonterminal to implement late
8590 reduction of constructs like `int ((int)(int)(int))'.
8591 (cast_expr): Use it.
8592 (sub_cast_expr): Everything that can come after a cast.
8593 (typed_declspecs1): typed_declspecs that are not typed_typespecs.
8594 (direct_after_type_declarator): Lose PAREN_STAR_PAREN rule.
8595 (direct_abstract_declarator): Replace '(' parmlist ')' rule with
8596 '(' complex_parmlist ')' and regcast_or_absdcl.
8598 (complex_parmlist): Parmlists that are not also typenames.
8599 (parms_comma): Enabler.
8600 (named_parm): A parm that is not also a typename. Use declarator
8601 rather than dont_see_typename abs_or_notype_decl. Expand
8602 typed_declspecs inline.
8603 (abs_or_notype_decl): Lose.
8604 (dont_see_typename): Comment out.
8605 (bad_parm): Break out abs_or_notype_decl into two rules.
8607 Fri Mar 4 18:22:39 1994 Jason Merrill (jason@deneb.cygnus.com)
8609 * decl2.c (reparse_decl_as_casts): New function to change parse
8610 nodes for `(int)(int)(int)' from "function taking int and returning
8611 function taking int and returning function taking int" to "... cast
8612 to int, cast to int, cast to int".
8614 * decl2.c (reparse_decl_as_expr): Recursive function to change
8615 parse nodes for `A()()' from "function returning function returning
8616 A" to "A().operator()".
8618 * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
8619 `typespec fcast_or_absdcl' rule.
8620 (fcast_or_absdcl): New nonterminal to implement late reduction of
8621 constructs like `A()()()()'.
8622 (typename): Replace `typespec absdcl1' rule with
8623 `typespec direct_abstract_declarator' rule.
8624 (direct_abstract_declarator): Replace `LEFT_RIGHT type_quals' rule
8625 with `fcast_or_absdcl type_quals' rule.
8627 Fri Mar 4 16:18:03 1994 Mike Stump <mrs@cygnus.com>
8629 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
8630 matches Section 5.5.
8632 Fri Mar 4 14:01:59 1994 Jason Merrill (jason@deneb.cygnus.com)
8634 * error.c (dump_type_prefix): Don't print basetype twice for
8637 Fri Mar 4 13:24:33 1994 Mike Stump <mrs@cygnus.com>
8639 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
8640 so that it is like setHandler(&A::handlerFn). Cures an `invalid
8641 lvalue in unary `&''.
8643 Fri Mar 4 11:15:59 1994 Jason Merrill (jason@deneb.cygnus.com)
8645 * gxxint.texi (Copying Objects): New section discussing default
8646 op= problems with virtual inheritance.
8648 * decl2.c (grokoptypename): Just does grokdeclarator and
8649 build_typename_overload, since the parser can't call grokdeclarator
8652 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
8653 and TREE_TYPE on generated identifiers.
8655 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.
8657 * parse.y (parm): Convert `const char *' to `__opPCc' here.

8660 if we can't figure out what to do.
8661 (dump_type*): Ditto.
8663 * typeck2.c (build_m_component_ref): 'component' is an expr, not
8664 a decl. Also move the IS_AGGR_TYPE check after the stripping of
8667 Fri Mar 4 04:46:05 1994 Mike Stump <mrs@cygnus.com>
8669 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
8670 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid
8671 lvalue in unary `&''.

8682 rather than waiting until later.
8684 Wed Mar 2 14:12:23 1994 Jason Merrill (jason@deneb.cygnus.com)
8686 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
8687 than expanding it inline.
8688 (typename): Expand empty option of (former) absdcl inline.
8689 (abs_or_notype_decl): Ditto.
8690 (absdcl): Lose empty rule.
8691 (conversion_declarator): New nonterminal for 'typename' of 'operator
8693 (operator_name): Use it instead of absdcl.
8695 * parse.y: Add precedence declarations for SCOPED_TYPENAME,

8698 directly. Add rules with reserved_typespecquals.
8699 (reserved_declspecs): Don't accept typespecqual_reserved at the
8700 beginning of the list. The typed_declspecs rule will deal with this
8702 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
8705 * parse.y (direct_notype_declarator,
8706 direct_after_type_declarator, direct_abstract_declarator): Split up
8707 the declarator1 nonterminals to match the draft standard and avoid
8709 (new_type_id, new_declarator, direct_new_declarator,
8710 new_member_declarator): New nonterminals to implement the subset of
8711 'typename' allowed in new expressions.
8712 (unary_expr): Use new_type_id instead of typename.

8722 previously duplicated in get_decl_list and list_hash_lookup_or_cons.
8723 (get_decl_list): Use it.
8724 (list_hash_lookup_or_cons): Ditto.
8726 * parse.y (typed_declspecs, declmods): It's not necessary to hash
8727 the declspecs on class_obstack, so don't. This way typed_typespecs
8728 can reduce to typed_declspecs.
8730 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
8732 * cvt.c (build_up_reference): If we aren't checking visibility,
8733 also allow base->derived conversions.
8735 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
8737 * typeck.c (build_c_cast): Remove bogus hack when converting
8738 to a reference type.
8740 * cp-tree.h (lang_decl::vbase_init_list, DECL_VBASE_INIT_LIST):
8742 (lang_stype::methods, lang_decl::next_method): New fields.
8743 (CLASSTYPE_METHODS, DECL_NEXT_METHOD): New macros.
8744 * decl.c (duplicate_decls): Preserve DECL_NEXT_METHOD.

8749 a non-inline virtual function to control emitting of vtables.
8750 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
8751 * search.c (build_vbase_vtables_init): Don't assemble_external
8752 (yet) if flag_vtable_hack.

8757 * parse.y (component_decl): Don't include "typed_declspecs
8758 declarator ';'" speedup, since it breaks enums.
8760 Fri Feb 25 15:43:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
8762 * class.c (finish_struct): Minor optimization for building

8769 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
8771 * lex.c (check_newline): #pragma interface can take a string
8772 argument, just like #pragma implementation. #pragma implementation
8773 checks for garbage on the line, line #pragma interface does. Main
8774 input files do not auto implement like named files, #pragma
8775 implementation must be used explicitly.
8777 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
8779 * parse.y (components): Handle list of one again.

8789 * Makefile.in (stamp-parse): Update expected conflict count.
8791 * parse.y (various): Replace "declmods declarator" with "declmods
8792 notype_declarator". The comment saying that "declmods declarator ';'"
8793 corresponds to "int i;" was wrong; it corresponds to "const i;".
8794 (component_decl): Add "typed_declspecs declarator ';'" rule; this
8795 *does* correspond to "int i;". Change "declmods components" to
8796 "declmods notype_components".
8797 (components): Don't deal with a list of one anymore.
8798 (notype_components): New nonterminal, corresponds to notype_declarator.

8804 (nontrivial_exprlist): New nonterminal: A list of at least two
8806 (nonnull_exprlist): Depend on nontrival_exprlist.
8807 Eliminates four reduce/reduce conflicts.
8809 (named_class_head): Move intermediate code block into separate
8810 nonterminal so that we can stick %prec EMPTY on it.
8812 Add more %prec EMPTY's to eliminate remaining shift/reduce
8815 (after_type_declarator): Add maybe_raises to fndecl rules.
8816 (after_type_declarator_no_typename): Remove.
8819 Document remaining reduce/reduce conflicts.

8823 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
8824 (TYPE_BINFO (type)) if we care about the path.
8826 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
8829 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>

8834 Sat Feb 19 01:27:14 1994 Jason Merrill (jason@deneb.cygnus.com)
8836 * parse.y: Eliminate 20 shift/reduce conflicts.
8838 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8840 * pt.c (type_unification): Add subr argument; if set, it means
8841 that we are calling ourselves recursively, so a partial match is OK.
8842 (unify): Support pointers to methods and functions.
8843 (tsubst): Support method pointers.
8844 * decl.c (build_ptrmemfunc_type): No longer static, so that
8845 tsubst can get at it.
8847 * init.c (is_aggr_typedef): Pretend template type parms are
8849 * decl2.c (build_push_scope): If cname refers to a template type
8850 parm, just grin and nod.
8852 * call.c (build_overload_call_real): Pass subr argument to
8854 * pt.c (do_function_instantiation): Ditto.
8855 * class.c (instantiate_type): Ditto.
8857 * search.c (get_base_distance): If BINFO is a binfo, use it and
8858 don't mess with its BINFO_INHERITANCE_CHAIN.
8860 * cvt.c (convert_to_reference): Fix temporary generation.
8861 If ambiguous, return error_mark_node.
8863 * init.c (build_new): Put back some necessary code.
8865 Thu Feb 17 15:39:47 1994 Jason Merrill (jason@deneb.cygnus.com)
8867 * init.c (build_new): Deal with array types properly.
8869 * search.c (get_binfo): Become a shell for get_base_distance.

8872 that provides the most access.
8873 (get_base_distance): Ditto.
8875 * parse.y (explicit_instantiation): Syntax is 'template class
8876 A<int>', not 'template A<int>'.
8878 * typeck.c (convert_for_initialization): Remove bogus warning.
8880 * parse.y (datadef): Revert patch of Oct 27.
8882 Thu Feb 17 15:12:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
8884 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,
8885 rather than integer_type_node. Does wonders for the Alpha.
8887 Thu Feb 17 13:36:21 1994 Jason Merrill (jason@deneb.cygnus.com)
8889 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
8890 goes onto the same obstack as its target type.
8892 Wed Feb 16 00:34:46 1994 Jason Merrill (jason@deneb.cygnus.com)
8894 * cvt.c (convert_to_reference): If converting via constructor
8895 on local level, go back to build_cplus_new approach.
8897 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
8898 to error_mark_node to prevent expand_expr from building a cleanup
8901 * lex.c (default_assign_ref_body): Return *this from the memcpy
8904 * decl.c (grok_reference_init): Just return if called with
8905 error_mark_node, don't worry about initializing non-const reference

8919 convert_to_reference. Generally do the right thing.
8921 * cvt.c (convert_to_reference): Conform to the initial comment;
8922 i.e. don't create temps if decl != error_mark_node. Handle
8923 cleanups better for temps that do get created. Don't pretend

8945 Remove NEW_CLASS_SCOPING, assuming it is always 1.

9787 to check if two fndecls are `the same'. Sometimes this routine can

9835 (lang_decode_option): Set warn_return_type, not explicit_*, for

9839 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.

9899 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
9900 properly with the case where a class contains an object of an
9901 ambiguous base class which has a protected op=. Should be fixed
9902 when the access control code gets overhauled.
