1092 Tue Aug 22 17:20:07 1995 Per Bothner <bothner@kalessin.cygnus.com>
1094 * decl2.c (flag_new_for_scope): Add a new mode that follows ANSI
1095 for-scoping, but supports (and warns about) old programs.
1096 Make the new mode (with value 1) the default.
1097 (lang_f_options): The on-value for flag_new_for_scope is now 2.
1098 * cp-tree.h (DECL_DEAD_FOR_LOCAL, DECL_ERROR_REPORTED): New macros
1099 (DECL_SHADOWED_FOR_VAR): Likewise.

1105 * lex.c (do_identifier): Handle old (non-ANSI) for scoping,
1106 and warn if conflicts.
1107 * parse.y (FOR): Call note_level_for_for.
1109 Mon Aug 21 10:28:31 1995 Jason Merrill <jason@deneb.cygnus.com>
1111 * decl2.c (import_export_inline): Class interface hackery does not
1112 apply to synthesized methods.
1114 Sun Aug 20 16:29:00 1995 Mike Stump <mrs@cygnus.com>
1116 * search.c (virtual_context): Find the right context more often.
1117 Solves a `recoverable compiler error, fixups for virtual function'
1120 Sun Aug 20 13:53:24 1995 Mike Stump <mrs@cygnus.com>
1122 * except.c (expand_start_all_catch): Ensure that we always transfer
1123 control to the right EH handler, by rethrowing the end label on the
1124 region, instead of hoping we are nested and falling through.
1125 (expand_leftover_cleanups): Ditto.
1126 (end_protect): Since we now rethrow the end label, put a
1127 nop after it, so that outer regions are recognized.
1128 * init.c (build_vec_delete_1): New routine to handle most of vector
1129 deleting, all code moved here from build_vec_delete.
1130 (build_array_eh_cleanup): Use build_vec_delete_1 to do all the real
1132 (expand_vec_init): If the array needs partial destructing, setup an
1133 EH region to handle it.
1134 (build_vec_delete): Move lots of code to build_vec_delete_1, use
1135 build_vec_delete_1 to do the grunt work.
1137 Sat Aug 19 14:25:33 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1139 Handle decl attributes properly for function definitions without
1140 previous attribute-loaded declarations.
1141 * decl.c (start_function): New arg ATTRS. Add a call to
1142 cplus_decl_attributes with it before we create the RTL.
1143 * cp-tree.h (start_function): Update prototype.
1144 * parse.y (fn.def1): Pass ATTRS into start_function instead of
1145 trying to call cplus_decl_attributes too late. Pass a NULL_TREE
1147 * decl2.c (finish_file): Pass NULL_TREE as fourth arg to
1149 * method.c (synthesize_method): Likewise.
1150 * except.c (expand_builtin_throw): Likewise for start on __throw.
1152 Sat Aug 19 13:36:08 1995 Mike Stump <mrs@cygnus.com>
1154 * class.c (set_rtti_entry): Turn on -fvtable-thunk -frtti support.
1155 This changes -fvtable-thunks vtable layout, so a recompile will be
1156 necessary, if you use -fvtable-thunks.
1157 (get_vtable_entry): Use n, instead of i to be consistent with the
1158 rest of the compiler.
1159 (get_vtable_entry_n): Ditto.

1174 * cp-tree.h (skip_rtti_stuff): New routine, declare it.
1175 * gc.c (build_headof): Support -fvtable-thunk and -frtti together.

1192 can be used for class template definitions, as well.
1193 (finish_struct_1): New function with the rest of the code.
1195 Tue Aug 15 09:46:16 1995 Mike Stump <mrs@cygnus.com>
1197 * class.c (prepare_fresh_vtable): On second though, always build the
1198 offset (see Aug 10 change), unless -fvtable-thunks is given. It
1199 does this by calling the new routine set_rtti_entry.
1200 (finish_struct): Ditto.
1201 (set_rtti_entry): New routine to update the rtti information at the
1202 start of the vtable.
1204 Mon Aug 14 12:21:22 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1206 * error.c (dump_decl, case IDENTIFIER_NODE): Only work on a dtor
1207 if it's declared in the C++ language spec.
1208 (dump_function_decl): Likewise.
1209 (dump_function_name): Likewise.
1210 (ident_fndecl): Make sure we got something back from lookup_name.
1211 * decl.c (start_function): Likewise.
1213 Fri Aug 11 16:52:15 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1215 * call.c (build_method_call): Don't call build_new when calling a
1216 constructor without an instance.
1218 Thu Aug 10 20:00:17 1995 Mike Stump <mrs@cygnus.com>
1220 * class.c (prepare_fresh_vtable): Always build the offset to the
1221 complete object, as it doesn't cost much. This allows dynamic_cast
1222 to void * to work when -frtti isn't given.
1223 (finish_struct): Ditto.
1225 Thu Aug 10 16:31:28 1995 Mike Stump <mrs@cygnus.com>
1227 * except.c (build_eh_type): Split out some functionality to new
1228 routine named build_eh_type_type.
1229 (build_eh_type_type): New routine.
1230 (expand_start_catch_block): Use build_eh_type_type, as we never want
1231 the dynamic type of the catch parameter, just the static type.
1232 Fixes core dumps when -frtti is used and one catchs pointers to
1235 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
1237 * except.c (expand_builtin_throw): Since we now use normal calling
1238 conventions for __throw, we have to remove the first layer off the
1239 stack, so that the next context we search for handlers is the outer
1240 context instead of the context that had the call to __throw, if we
1241 don't immediately find the desired context.
1243 Tue Aug 8 17:44:23 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1245 * tree.c (cp_expand_decl_cleanup): Returns int, not tree.
1246 * cp-tree.h: Update.

1258 (throw_label): Removed.
1259 (expand_builtin_throw): Changed so that EH parameters are passed by
1260 normal function call conventions. Completes Aug 4th work.
1262 Fri Aug 4 17:17:08 1995 Mike Stump <mrs@cygnus.com>
1264 * cp-tree.h (expand_builtin_throw): Declare it.
1265 * decl2.c (finish_file): Call expand_builtin_throw.
1266 * except.c (make_first_label): Remove.
1267 (init_exception_processing): Don't use a LABEL_REF for throw_label,
1268 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
1269 other functions that don't really appear in those functions. This
1270 solves a problem where cc1plus consumed exponential amounts of
1271 memory when -Wall was used.
1272 (expand_end_all_catch, expand_leftover_cleanups,
1273 expand_end_catch_block, expand_throw): Change all uses of
1274 throw_label to match new style.
1275 (do_unwind): Rename parameter to inner_throw_label, as it is now
1276 different from throw_label. Also, assume that our caller will wrap
1277 the passed label with a LABEL_REF, if needed.
1278 (expand_builtin_throw): Make external, change so that the generated
1279 throw is now a real function.
1280 (expand_exception_blocks): Never generate throw code inside another
1283 Fri Aug 4 12:20:02 1995 Mike Stump <mrs@cygnus.com>
1285 * decl.c (grokdeclarator): Move checking of mutable const objects
1286 and mutable static objects down, as we might decide during parsing
1287 to unset staticp or constp (for example, when const is part of the
1288 object being pointed to).
1290 Thu Aug 3 17:13:43 1995 Mike Stump <mrs@cygnus.com>
1292 * except.c (output_exception_table_entry): Enhance portability to
1294 (emit_exception_table): Ditto.

1314 exceptStack, exceptstack, push_except_stmts, pop_except_stmts,
1315 new_except_stack, push_last_insn, pop_last_insn, insn_save_node and
1316 InsnSave. Also, numerous speed improvements, and correctness
1317 improvements. Double faulting in all situations should now be
1319 (expand_start_all_catch): Instead of having many terminate protected
1320 regions, just have one.
1321 (expand_start_catch_block): No longer have to protect
1322 false_label_rtx, as it isn't used for EH region marking.
1323 (expand_end_catch_block): Expand out EH cleanups here by using
1324 expand_leftover_cleanups.
1325 (expand_end_all_catch): Use sequences instead of playing with insn
1327 (expand_exception_blocks): Ditto. Also protect all catch clauses
1328 with one terminate region.
1330 Mon Jul 31 13:24:30 1995 Jason Merrill <jason@phydeaux.cygnus.com>
1332 * method.c (report_type_mismatch): Don't talk about an object
1333 parameter for non-methods.

1377 * tree.c (unsave_expr): New routine to build an UNSAVE_EXPR.
1378 (unsave_expr_now): Backend routine used by tree expander.
1379 (cp_expand_decl_cleanup): Wrap second argument in an UNSAVE_EXPR to
1380 work around a limitation in the backend. The backend uses the
1381 cleanups multiple times, on disjoint control flows, so we cannot
1382 pass unsaved SAVE_EXPRs to the backend.
1383 * tree.def (UNSAVE_EXPR): New tree code.
1384 * typeck.c (c_expand_return): Move goto/return code up inside
1385 conditional, as we don't always want to do this, we only want to do
1386 this when we don't otherwise finish with this control flow.
1388 Thu Jul 27 10:38:43 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1390 * parse.y (typespec): Only complain about typeof if we're not
1391 getting it from a system header.

1413 * call.c (convert_harshness): Deal with reference conversions before
1414 others. Actually do array->pointer decay. Call comp_target_types
1415 with pointer types rather than their targets.

1419 Mon Jul 24 08:54:46 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1421 * pt.c (to_be_restored): Move decl to global scope.

1438 * decl.c (start_decl): Handle declarations of member functions
1439 outside of the class (i.e. specialization declarations).

1450 is not a parameter list (TREE_LIST).
1451 (expand_default_init): If LOOKUP_ONLYCONVERTING is set, then set
1452 LOOKUP_NO_CONVERSION so that we don't allow two-level conversions,
1453 but don't set it otherwise.

1457 * init.c (expand_default_init): Don't allow two-level conversions

1499 aligned at a 64 bit boundary on the Alpha.
1500 * sig.c (build_signature_table_constructor): Build the constructor
1501 according to the new layout. Set the vb_off field to -1 for now.
1503 * decl.c (init_decl_processing): Align sigtable_entry_type on word
1504 boundaries instead of double word boundaries to save space.

1532 * decl.c (cp_finish_decl): Only destruct local static variables if
1533 they are constructed, and only construct the first time control
1534 passes completely through its declaration (if not initialized with a
1535 constant-expression).
1536 (expand_static_init): Ditto.
1538 Wed Jul 5 14:05:04 1995 Brendan Kehoe <brendan@lisa.cygnus.com>
1540 * typeck.c (comptypes, case OFFSET_REF): If either offset basetype
1541 is a TEMPLATE_TYPE_PARM, give a match.

1869 (push_template_decls): Ditto.
1870 (grok_template_type): Deleted as template parameters are shared

3694 initializer. Also Pick up any new tdecls or vtables needed by
3695 synthesized methods.
3697 * class.c (finish_struct): Simplify. We have to do rtti scanning at
3698 end, so we might as well do all of it there.

3712 * decl2.c (finish_file): Call finish_prevtable_vardecl.
3713 * gc.c (build_generic_desc): Allow it to be called when not at the
3714 global binding layer, but behave as if we were.
3715 (build_t_desc): Rearrange a bit so that it really works and is
3717 * class.c (finish_struct): Don't decide on tdecls here, as we have
3718 to wait until the end of the file in general to decide whether or

3752 * decl2.c (finish_vtable_vardecl): Now set the
3753 interface/implementation of vtables on the first virtual function,
3754 if one exists, otherwise we use the old method. This is a major win
3755 in terms of cutting down the size of objects and executables in
3756 terms of text space and data space. Now most of the savings that
3757 #pragma interface/implementation gives is automatic in a fair number

3776 * parse.y: Add END_OF_LINE token.
3778 * lex.c (check_newline): Set linemode when we see a # directive, and
3779 unset it when we're done. Turn all 'return's into 'goto skipline'.

3781 character we read before checking for a sysv or target pragma.
3782 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.

3814 * pt.c (tsubst): When we copy a node, don't forget to copy

3819 * typeck.c (convert_for_assignment): Initialize variable before use.

5306 for the message so they know at what point it was instantiated.

7414 expand_indirect_vtbls_init. Change init_vtbl_ptrs call to

7425 DECL_CONTEXT. That is now done in a cleaner way in
7426 modify_vtable_entry and add_virtual_function.
7427 * search.c (expand_vbase_vtables_init): Rename to
7428 expand_indirect_vtbls_init. General cleanup. Use
7429 expand_direct_vtbls_init to do hard work. Ensures that _all_ vtable
7430 pointers from virtual bases are set up.
7431 * search.c (bfs_unmark_finished_struct, unmark_finished_struct):
7434 * *.[chy]: Remove support for VTABLE_USES_MASK.
7436 Tue Apr 19 12:51:59 1994 Jason Merrill (jason@deneb.cygnus.com)
7438 * cvt.c (convert_to_reference): Use NOP_EXPRs to switch between
7439 reference and pointer types instead of bashing the types directly.
7441 * call.c (build_overload_call_real): Use the TREE_CODE to determine
7442 whether the function is overloaded or not, rather than
7444 * *: Remove all uses of TREE_OVERLOADED.
7446 * decl.c (grokdeclarator): Only complain about initializing const
7447 fields when -ansi or -pedantic.

7457 (struct binding_level): Add overloads_shadowed field.
7458 (poplevel): Restore overloads_shadowed.

7488 before we get to left_curly.
7489 * pt.c (instantiate_class_template): Set TYPE_BEING_DEFINED.
7491 * error.c (dump_decl): If it's a typedef, print out the name of the
7492 decl, not just the underlying type.
7494 * decl.c (pushdecl): If the old duplicate decl was a TYPE_DECL,
7495 update the IDENTIFIER_TYPE_VALUE of its name.
7497 * decl2.c (finish_file): When processing the initializer for a
7498 static member, pretend that the dummy function is a member of the

7519 Fri Apr 15 13:19:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
7521 * method.c (emit_thunk): Add extern declaration for
7522 current_call_is_indirect (needed for hppa).
7524 Thu Apr 14 16:12:31 1994 Jason Merrill (jason@deneb.cygnus.com)
7526 Improve local class support; allow classes in different blocks to
7528 * decl.c (pushtag): Support local classes better.
7529 (pushdecl_nonclass_level): New function for pushing mangled decls of
7530 nested types into the appropriate scope.
7531 (xref_defn_tag): Use pushdecl_nonclass_level instead of
7533 (grokfndecl): Don't mess with IDENTIFIER_GLOBAL_VALUE for local
7535 * method.c (do_inline_function_hair): Ditto.
7537 * class.c (finish_struct): It is legal for a class with no
7538 constructors to have nonstatic const and reference members.
7540 Thu Apr 14 07:15:11 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7542 * decl.c (push_overloaded_decl): Avoid giving errors about
7543 built-ins, since duplicate_decls will have given warnings/errors
7546 Thu Apr 14 03:45:12 1994 Jason Merrill (jason@deneb.cygnus.com)
7548 * cvt.c (convert_to_reference): Warn about casting pointer type to
7549 reference type when this is probably not what they wanted.
7551 Wed Apr 13 13:12:35 1994 Per Bothner (bothner@kalessin.cygnus.com)
7553 * decl.c (finish_decl): Don't mindlessly set TREE_USED for
7554 static consts any more (toplev.c has now been modified to
7555 not emit warnings if they are unused).
7557 Wed Apr 13 00:22:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7559 * decl.c (grok_op_properties): If op new/delete get here with
7560 METHOD_TYPEs, do a revert_static_member_fn.
7562 * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
7563 * init.c (is_aggr_typedef): Don't look at
7564 IDENTIFIER_CLASS_TYPE_VALUE.
7565 (get_aggr_from_typedef): Ditto.
7566 (get_type_value): Ditto.
7567 * call.c (build_scoped_method_call): Don't rely on overloaded
7568 template names having IDENTIFIER_CLASS_VALUE set.
7570 * parse.y (component_decl_1, fn.def2): Revert rules for
7572 (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
7575 * decl.c (start_function): Only warn about `void main()' if pedantic
7576 || warn_return_type.
7578 Tue Apr 12 02:14:17 1994 Jason Merrill (jason@deneb.cygnus.com)
7580 Clean up overloading of the template name.
7581 * class.c (pushclass): overload the template name whenever pushing
7582 into the scope of a template class, not just if it is
7584 (popclass): Correspondingly.
7585 * search.c (push_class_decls): Don't overload_template_name.
7586 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
7587 DECL_CONTEXT on things.
7588 * parse.y (left_curly): Don't overload_template_name.
7589 * class.c (finish_struct): Don't undo_template_name_overload.
7591 * method.c (build_opfncall): Only pass one argument to global op
7594 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
7595 decide how many arguments to use for vec delete.
7597 * decl.c (grok_op_properties): Be consistent in modifying
7599 (grokdeclarator): Only complain about function decls with no return
7600 type if we're being pedantic.
7602 Mon Apr 11 00:10:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7604 Add support for operator new [] and operator delete [].
7606 * tree.def: Add VEC_NEW_EXPR and VEC_DELETE_EXPR.
7607 * ptree.c (print_lang_type): Indicate vec new/delete.
7608 * parse.y: Support vec new/delete.
7609 * method.c (build_decl_overload): Deal with vec new/delete.
7610 (build_opfncall): Ditto.
7611 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
7612 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
7613 * init.c (init_init_processing): Set up BIVN and BIVD.
7614 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
7615 since it doesn't happen any more.
7616 (build_new): Support vec new. Always call something.
7617 (build_x_delete): Support vec delete.
7618 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
7619 and pass it to build_x_delete.
7620 * decl2.c (delete_sanity): Don't change behavior by whether or not
7621 the type has a destructor. Pass use_global_delete to
7623 (coerce_delete_type): Make sure that the type returned has a first
7624 argument of ptr_type_node.
7625 * decl.c (init_decl_processing): Also declare the global vec
7627 (grokdeclarator): Also force vec new/delete to be static.
7628 (grok_op_properties): Note presence of vec new/delete, and play with
7629 their args. If vec delete takes the optional size_t argument, set
7630 TYPE_VEC_DELETE_TAKES_SIZE.
7631 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
7632 checking for one delete or the other.
7633 (lang_type): gets_new and gets_delete are now two bits long. The
7634 low bit is for the non-array version. Lose gets_placed_new.
7635 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
7636 delete defined by this class wants to know how much space it is
7638 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
7639 add a header containing the number of elements in the vector; i.e.
7640 when the elements need to be destroyed or vec delete wants to know
7642 * class.c (finish_struct_methods): Also check for overloading vec
7644 * call.c (build_method_call): Also delete second argument for vec
7647 * decl.c (grokdeclarator): Correct complaints again.
7648 (grokdeclarator): Fix segfault on null declarator.
7649 (decls_match): Also accept redeclaration with no arguments if both
7650 declarations were in C context. Bash TREE_TYPE (newdecl) here.
7651 (duplicate_decls): Instead of here.
7653 * parse.y (nested_name_specifier_1): Lose rules for dealing with
7654 syntax errors nicely, since they break parsing of 'const i;'.
7656 * decl.c (lookup_name): if (got_scope == current_class_type)
7657 val = IDENTIFIER_CLASS_VALUE (name).
7659 * search.c (lookup_nested_tag): Look in enclosing classes, too.
7661 * spew.c (yylex): Only look one character ahead when checking for a
7664 * lex.c (check_newline): Read first nonwhite char before
7665 incrementing lineno.
7667 * decl.c (grokdeclarator): Don't claim that typedefs are variables
7670 * parse.y: Divide up uses of unqualified_id into
7671 notype_unqualified_id and unqualified_id, so that TYPENAME can be
7672 used as an identifier after an object.
7674 * class.c (push_nested_class): Don't push into non-class scope.
7676 * decl.c (grokdeclarator): If an identifier could be a type
7677 conversion operator, but has no associated type, it's not a type
7678 conversion operator.
7680 * pt.c (unify): Check for equality of constants better.
7682 * decl.c (grokdeclarator): Don't complain about access decls.
7684 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
7686 * decl.c (grokdeclarator): pedwarn about data definitions without
7689 * parse.y (datadef): Don't pedwarn about decls without types here,
7690 since that is valid for functions.
7691 (fn.def2, component_decl): Support constructors with declmods again.
7692 (nomods_initdecls): For decls without any mods, so that we don't try
7693 to get declspecs from some arbitrary $0.
7695 * search.c (lookup_field): Use cp_error.
7697 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
7698 here; it breaks destructors for non-aggr types.
7700 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
7701 a type being defined, like the comment says.
7702 If got_scope is not an aggregate, just return NULL_TREE.
7704 * pt.c (create_nested_upt): Kung's code for creating types nested
7705 within uninstantiated templates now lives here (it used to live in
7706 hack_more_ids). It needs to be expanded.
7708 * parse.y: Stop calling see_typename so much.
7710 * decl.c (lookup_name): Deal with TTPs and UPTs.
7712 * lex.c (real_yylex): Don't set looking_for_typename just because we
7714 (dont_see_typename): #if 0 out.
7716 * spew.c (yylex): Increment looking_for_typename if the next
7717 character is SCOPE, rather than setting it to 1; this way, the value
7718 from seeing an aggr specifier will not be lost. This kinda relies
7719 on looking_for_typename never being < 0, which is now true.
7721 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
7723 (named_class_head_sans_basetype): Accept template types, too. Oops.
7725 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7727 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
7729 * parse.y: Lose START_DECLARATOR.
7731 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
7734 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
7735 A::foo' syntax. Catch invalid scopes better.
7737 * parse.y, lex.c: lose TYPENAME_COLON.
7739 * decl2.c (groktypefield): #if 0 out.
7741 * decl.c (lookup_name): If the type denoted by got_scope is
7742 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
7744 * class.c (push_nested_class): Don't try to push into
7747 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7749 * Makefile.in (stamp-parse): Update count of conflicts to 33.
7751 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7753 A saner implementation of nested types that treats template types
7754 no differently from non-template types. There are still some
7755 shortcomings of our system; most notably, it is difficult to look
7756 for a nested type that is hidden by another name, because of the way
7757 we keep track of hidden types. But this shouldn't be a problem for
7758 just about anyone. Perhaps lookup_field should be fixed up a bit.
7760 * spew.c: Moved handling of nested types/scoping from the lexer
7761 into the parser. Removed variable template_type_seen_before_scope.
7762 Removed functions frob_identifier, hack_more_ids, and various cruft
7763 that was #if 0'd out in the past, reducing the size of the file from
7764 1146 lines to 450 lines. We can't quite do away with spew.c yet,
7765 though; we still need it for do_aggr () and checking for SCOPE after
7766 the current identifier. And setting lastiddecl.
7768 * parse.y: Moved handling of nested types/scoping from the lexer
7769 into the parser, using a new global variable `got_scope'. Reduced
7770 the number of states by 53. Implemented all uses of explicit global
7771 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
7772 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
7773 scoped_typename. Added nonterminals nested_type,
7774 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
7775 nested_name_specifier, global_scope, overqualified_id, type_name.
7776 Changed many others. Added 9 new reduce/reduce conflicts, which are
7777 nested type parallels of 9 that were already in the grammar for
7778 non-nested types. Eight of the now 33 conflicts should be removed
7779 in the process of resolving the late binding between variable and
7782 * gxxint.texi (Parser): Update.
7784 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
7786 * lex.h: Add decl for got_scope.
7788 * lex.c (see_typename): Claim to be the lexer when calling
7791 * decl.c (lookup_name): When called from the lexer, look at
7792 got_scope and looking_at_typename; otherwise don't.
7794 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
7796 31th Cygnus<->FSF merge.
7798 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7800 * decl2.c (mark_vtable_entries): Call this to mark all the
7801 entries in the vtable addressable.
7802 (finish_decl_parsing): Handle SCOPE_REFs.
7804 * decl.c (decls_match): Always call compparms with strict == 1.
7805 Handle the special case of C function redecl here.
7806 (duplicate_decls): Only keep the old type if the new decl takes no
7809 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.

7816 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
7818 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
7819 ch-tree.h: Every place these functions were called, the result was
7820 immediately passed to expand_expr_stmt. Reduce redundancy by
7821 calling expand_expr_init *inside* these functions. These
7822 makes for a simpler interface, and we don't have to build
7823 compound expressions. Hence, rename these function to:
7824 expand_virtual_init and expand_vbase_vtables_init respectively.
7825 * init.c, decl.c: Change callers of these functions.
7826 * init.c, cp-tree.h (expand_virtual_init): Make static.
7828 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
7829 rather than DECL_SAVED_INSNS before emitting inlines.

7833 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
7835 * decl.c (duplicate_decls): If this is a new declaration of an
7836 extern "C" function, keep the type (for the argtypes).
7837 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
7838 (decls_match): Call compparms with a value of strict dependent on
7839 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
7841 * typeck.c (compparms): ... is only equivalent to non-promoting
7842 parms if we're not being strict.
7844 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
7846 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
7847 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
7849 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

7861 to add delta field from vtable (there is none!).
7862 * decl.c: Add memptr_type as well as vtable_entry_type.
7863 If using thunks, the latter is just ptr_type_node.
7864 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
7865 * decl2.c (finish_vtable_vardecl): Handle thunks.

7868 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
7869 * decl.c (start_function): Set current_extern_inline based on
7870 DECL_THIS_EXTERN, not TREE_PUBLIC.

7879 * decl2.c (mark_inline_for_output): Do nothing if
7880 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
7881 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
7882 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.

7885 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
7887 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
7888 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
7889 instead. (The rationale is that these optimizations both break binary
7890 compatibility, but should become the default in a future release.)

7894 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT

7905 * typeck.c (c_expand_return): Before checking that we're not
7906 returning the address of a local, make sure it's a VAR_DECL.
7907 (And don't worry about it being a TREE_LIST.)

7911 * parse.y (YYDEBUG): Always define.
7912 * lex.c (YYDEBUG): Ditto.
7914 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)

8059 * decl.c (start_method): Methods defined in the class body are
8060 inline whether or not it's a template class.

8087 * typeck.c (comp_target_types): Call comp_target_parms with

8196 Tue Mar 22 12:44:54 1994 Jason Merrill (jason@deneb.cygnus.com)
8198 These patches implement handling of redefinition/redeclaration of
8201 * typeck.c (comptypes): Simplify. All TEMPLATE_TYPE_PARMs are
8202 considered compatible.
8204 * parse.y (template_def): Pass defn argument to end_template_decl.
8206 * pt.c (end_template_decl): Add defn argument. Check for
8207 redefinition. Simplify.
8209 * error.c (OB_UNPUT): New macro, to remove mistakes.
8210 (aggr_variety): Subroutine of dump_aggr_type.
8212 * decl.c (decls_match): Support templates.

8222 * error.c (dump_decl): Support class template decls.
8223 (dump_type): Don't adorn template type parms.
8225 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl

8232 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
8233 in FIELD context, when appropriate. Also,
8234 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
8235 Also, simplify check for bogus return specifiers.
8237 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
8239 * parse.y (after_type_declarator1): Expand type_quals.
8240 (notype_declarator1): Ditto.
8243 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
8245 * decl.c (grokdeclarator): Treat class-local typedefs like static
8246 members; i.e. 'typedef int f();' means that f is a function type,
8249 * parse.y (decl): Change direct_* back to *.
8250 (type_id): Change direct_abstract_declarator to absdcl.
8251 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.

8258 * class.c (current_lang_stacksize): No longer static.

8263 (pop_from_top_level): Restore them.
8265 * gxxint.texi (Parser): Update.
8267 These two patches finish moving the task of expr/declarator
8268 ambiguity resolution from the lexer to the parser, and add one more
8269 r/r conflict. START_DECLARATOR can now be nuked.
8271 * parse.y (decl): Add "direct_" in typespec X rules.
8272 (direct_declarator): New nonterminal for
8273 direct_after_type_declarator and direct_notype_declarator.

8276 (named_parm): Add typespec direct_declarator rule.
8278 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
8280 These two patches disable some excessive cleverness on the part of
8281 g++; a non-class declaration always hides a class declaration in the
8282 same scope, and g++ was trying to unhide it depending on the
8283 enclosing expression.
8285 * spew.c (arbitrate_lookup): #if 0 out.
8287 * decl.c (lookup_name): Never call arbitrate_lookup.
8289 * parse.y (complex_notype_declarator1): Add '*'
8290 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
8292 * parse.y (complex_direct_notype_declarator): Restore id_scope
8293 see_typename TYPENAME rule, remove all other rules beginning with
8295 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
8297 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
8299 These changes fix the compiler's handling of the functional cast/
8300 object declaration ambiguities in section 6.8 of the ARM. They also
8301 add 11 reduce/reduce conflicts. Sigh.
8303 * parse.y: Add precedence decls for OPERATOR and '~'.
8304 (notype_unqualified_id): New nonterminal, encompasses all of the
8305 ANSI unqualified-id nonterminal except TYPENAMEs.
8306 (expr_or_declarator): New nonterminal to delay parsing of code like
8308 (primary): Use notype_unqualified_id.
8309 (decl): Add typespec initdecls ';' and typespec declarator ';'
8311 (initdcl0): Deal with the above.
8312 (complex_notype_declarator1): A notype_declarator that is not also
8313 an expr_or_declarator.
8314 (complex_direct_notype_declarator): A direct_notype_declarator that
8315 doesn't conflict with expr_or_declarator. Use
8316 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
8317 (functional_cast): New nonterminal, for the three functional cast
8318 rules. So that they can be moved after
8319 complex_direct_notype_declarator.
8320 (see_typename): Don't accept type_quals any more.
8322 * decl2.c (reparse_decl_as_expr): New function to deal with parse
8323 nodes for code like `int (*a)++;'.
8324 (reparse_decl_as_expr1): Recursive subroutine of the above.
8325 (finish_decl_parsing): New function to deal with parse nodes for
8326 code like `int (*a);'. See the difference?
8328 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
8330 These changes break binary compatibility in code with classes
8331 that use virtual bases.
8333 * search.c (dfs_get_vbase_types): Simplify and correct to make
8334 sure virtual bases are initialized in dfs ordering.
8335 * search.c (get_vbase_types): Simplify and make readable.
8337 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)

8352 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
8353 all of the scoped PTYPENAME rules.
8355 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
8357 * init.c (build_offset_ref): The value of A::typedef_name is
8358 always the TYPE_DECL, and never an error.
8360 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8362 * search.c (get_base_distance_recursive): Two binfos can only
8363 represent the same object if they are both via_virtual.
8365 * class.c (finish_base_struct): Check vbases for ambiguity, too.
8367 * search.c (get_vbase_types): Accept binfo argument, too.
8369 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
8371 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
8372 initializer also, because back-end requires it.
8374 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
8376 * error.c (dump_expr): Support member functions (which show up as
8379 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>

8416 (dont_see_typename): Comment out.
8417 (bad_parm): Break out abs_or_notype_decl into two rules.

8426 * decl2.c (reparse_decl_as_expr): Recursive function to change
8427 parse nodes for `A()()' from "function returning function returning

8441 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
8442 matches Section 5.5.

8457 * gxxint.texi (Copying Objects): New section discussing default
8458 op= problems with virtual inheritance.

8501 (abs_or_notype_decl): Ditto.
8502 (absdcl): Lose empty rule.
8503 (conversion_declarator): New nonterminal for 'typename' of 'operator

8510 directly. Add rules with reserved_typespecquals.
8511 (reserved_declspecs): Don't accept typespecqual_reserved at the
8512 beginning of the list. The typed_declspecs rule will deal with this
8514 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
8517 * parse.y (direct_notype_declarator,
8518 direct_after_type_declarator, direct_abstract_declarator): Split up
8519 the declarator1 nonterminals to match the draft standard and avoid

8534 previously duplicated in get_decl_list and list_hash_lookup_or_cons.
8535 (get_decl_list): Use it.
8536 (list_hash_lookup_or_cons): Ditto.
8538 * parse.y (typed_declspecs, declmods): It's not necessary to hash
8539 the declspecs on class_obstack, so don't. This way typed_typespecs
8540 can reduce to typed_declspecs.
8542 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
8544 * cvt.c (build_up_reference): If we aren't checking visibility,
8545 also allow base->derived conversions.

8562 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
8563 * search.c (build_vbase_vtables_init): Don't assemble_external

8569 * parse.y (component_decl): Don't include "typed_declspecs

8581 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
8583 * lex.c (check_newline): #pragma interface can take a string
8584 argument, just like #pragma implementation. #pragma implementation
8585 checks for garbage on the line, line #pragma interface does. Main
8586 input files do not auto implement like named files, #pragma
8587 implementation must be used explicitly.

8601 * Makefile.in (stamp-parse): Update expected conflict count.
8603 * parse.y (various): Replace "declmods declarator" with "declmods
8604 notype_declarator". The comment saying that "declmods declarator ';'"
8605 corresponds to "int i;" was wrong; it corresponds to "const i;".
8606 (component_decl): Add "typed_declspecs declarator ';'" rule; this
8607 *does* correspond to "int i;". Change "declmods components" to
8608 "declmods notype_components".
8609 (components): Don't deal with a list of one anymore.
8610 (notype_components): New nonterminal, corresponds to notype_declarator.

8627 (after_type_declarator): Add maybe_raises to fndecl rules.
8628 (after_type_declarator_no_typename): Remove.
8631 Document remaining reduce/reduce conflicts.

8635 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
8636 (TYPE_BINFO (type)) if we care about the path.
8638 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
8641 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>

8648 * parse.y: Eliminate 20 shift/reduce conflicts.
8650 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8652 * pt.c (type_unification): Add subr argument; if set, it means
8653 that we are calling ourselves recursively, so a partial match is OK.
8654 (unify): Support pointers to methods and functions.
8655 (tsubst): Support method pointers.
8656 * decl.c (build_ptrmemfunc_type): No longer static, so that

8661 * decl2.c (build_push_scope): If cname refers to a template type
8662 parm, just grin and nod.

8666 * pt.c (do_function_instantiation): Ditto.
8667 * class.c (instantiate_type): Ditto.
8669 * search.c (get_base_distance): If BINFO is a binfo, use it and

8673 If ambiguous, return error_mark_node.
8675 * init.c (build_new): Put back some necessary code.

8701 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
8702 goes onto the same obstack as its target type.
8704 Wed Feb 16 00:34:46 1994 Jason Merrill (jason@deneb.cygnus.com)
8706 * cvt.c (convert_to_reference): If converting via constructor
8707 on local level, go back to build_cplus_new approach.
8709 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
8710 to error_mark_node to prevent expand_expr from building a cleanup
8713 * lex.c (default_assign_ref_body): Return *this from the memcpy
8716 * decl.c (grok_reference_init): Just return if called with
8717 error_mark_node, don't worry about initializing non-const reference
8720 * cvt.c (convert_to_reference): Do the right thing for
8721 non-aggregate reference conversions, pedwarn when generating a
8722 non-const reference to a temporary.
8724 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
8725 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
8728 Tue Feb 15 19:47:19 1994 Jason Merrill (jason@deneb.cygnus.com)
8730 * decl.c (grok_reference_init): Pawn off a lot of the work on
8731 convert_to_reference. Generally do the right thing.
8733 * cvt.c (convert_to_reference): Conform to the initial comment;
8734 i.e. don't create temps if decl != error_mark_node. Handle
8735 cleanups better for temps that do get created. Don't pretend
8736 that we can use an 'A' to initialize a 'const double &' just by
8737 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
8739 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

8751 (which isn't always the inner_binding_level).
8753 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
8754 It's ugly, and I don't think it's the right thing to do.
8756 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
8757 Remove NEW_CLASS_SCOPING, assuming it is always 1.
8758 * decl.c (pop_decl_level): Removed; manually inlined.

8780 with destructor names when either NO_DOLLAR_IN_LABEL or

8785 * pt.c (grok_template_type): substitute template parm types
8786 with actual types in complex type as well.
8787 (coerce_template_parms): update the grok_template_type ()
8790 * pt.c (tsubst): Traverse method list using DECL_CHAIN.
8792 * decl.c (grok_op_properties): Allow operator++/-- to have
8795 * typeck2.c (store_init_value): Don't abort when called to
8796 initialize a type that needs constructing with a CONSTRUCTOR.
8798 * init.c (expand_aggr_init_1, CONSTRUCTOR case): If

8804 * class.c (build_vbase_path): Use complete_type_p instead of
8805 resolves_to_fixed_type_p to determine if the virtual bases are in
8806 their right place for the type of expr. Cures problem of thinking a
8807 virtual base class is one place, when it is in fact someplace else.
8809 Fri Feb 11 00:26:46 1994 Mike Stump <mrs@cygnus.com>
8811 * init.c (resolve_offset_ref): Make sure we first convert to
8812 intermediate type, if given, when dealing with members off `this'.
8813 Solves an incorrrect `type `foo' is not a base type for type
8814 `multiple'' when it is infact, a base type.
8816 Thu Feb 10 21:49:35 1994 Mike Stump <mrs@cygnus.com>
8818 * class.c (modify_other_vtable_entries): Use get_binfo, instead
8819 of binfo_value. Solves problem with compiler giving a `base class
8820 `B' ambiguous in binfo_value (compiler error)' on complex MI
8821 herarchies, when a virtual function is first defied in a virtual

8866 * decl.c (grokdeclarator): Don't complain about anonymous
8869 * parse.y (simple_stmt, for loops): Move the continue point after

8873 TYPE_HAS_COMPLEX_INIT_REF.
8875 Tue Feb 8 13:21:40 1994 Jason Merrill (jason@deneb.cygnus.com)
8877 * init.c (build_new): Deal with `new double (1)'.
8879 * class.c (finish_struct): TYPE_HAS_COMPLEX_*_REF are supersets of
8880 TYPE_HAS_REAL_*_REF, but TYPE_HAS_COMPLEX_INIT_REF is independent of
8881 TYPE_NEEDS_CONSTRUCTING.
8883 * decl.c (duplicate_decls): Propagate access decls.
8885 * typeck2.c (process_init_constructor): Accept empty_init_node
8886 for initializing unions.
8888 * class.c, lex.c, cp-tree.h: Use
8889 TYPE_HAS_COMPLEX_ASSIGN_REF where TYPE_HAS_REAL_ASSIGN_REF was used
8890 before, use TYPE_HAS_COMPLEX_INIT_REF for TYPE_NEEDS_CONSTRUCTING in

8894 if it was initialized before.

9598 * cp-class.c (modify_other_vtable_entries): Use DECL_ASSEMBLER_NAME
9599 to check if two fndecls are `the same'. Sometimes this routine can
9600 modify the main vtable, and normal should be 1, in that case, so use
9601 is_normal() to determine if this is the main vtable for the class.
9602 Don't recurse down virtual bases, as they are shared, and we take
9603 care of them elsewhere.

9605 vtable with the new virtual, don't do it again.
9606 * cp-class.c (finish_struct): Set CLASSTYPE_VFIELD_PARENT as

9647 (lang_decode_option): Set warn_return_type, not explicit_*, for
9648 -Wreturn-type and -Wall. This is what rest_of_compilation uses to
9649 decide if it should go into jump_optimize or not.

9651 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
9652 (finish_function): Also complain about no return in a non-void fn if
9653 we're being pedantic (don't rely on use of -Wreturn-type).

9710 * cp-class.c (finish_base_struct): Set cant_synth_* correctly.
9711 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
9712 properly with the case where a class contains an object of an
9713 ambiguous base class which has a protected op=. Should be fixed
9714 when the access control code gets overhauled.
9715 (finish_struct_methods): Set TYPE_HAS_NONPUBLIC_* correctly.

9773 only go for setting TRIVIAL_CODE if we are dealing with types that

9871 doing anything useful. Instead, sort once, and DO NOT wipe
