1329 (xref_tag): Split out base handling into xref_basetypes.
1331 * cp-tree.h (TYPE_INCOMPLETE): New macro; TEMPLATE_TYPE_PARMs are

1334 * decl.c (xref_defn_tag): Lose.
1335 (xref_tag): xref_next_defn = ! globalize.
1336 (pushdecl): Don't set DECL_NESTED_TYPENAME on artificial decls. The

1340 (set_nested_typename): Push a decl for the nested typename from
1341 here, rather than from xref_defn_tag.
1343 * parse.y (do_xref): Lose.
1344 (named_class_head): If we see 'class foo:' we know it's a
1345 definition, so don't worry about base lists for non-definitions.
1347 * pt.c (push_template_decls): Template parm decls are artificial.
1349 * decl.c (duplicate_decls): Restore check for qualifier
1350 disagreement for non-functions.

1406 (finish_file): Move finish_prevtable_vardecl up to before the global
1407 initializers are done as tdecls are initialized in the global
1408 initializer. Also Pick up any new tdecls or vtables needed by
1409 synthesized methods.
1411 * class.c (finish_struct): Simplify. We have to do rtti scanning at
1412 end, so we might as well do all of it there.

1416 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

1425 in finish_prevtable_vardecl.
1426 * decl2.c (finish_file): Call finish_prevtable_vardecl.
1427 * gc.c (build_generic_desc): Allow it to be called when not at the

1429 (build_t_desc): Rearrange a bit so that it really works and is
1431 * class.c (finish_struct): Don't decide on tdecls here, as we have
1432 to wait until the end of the file in general to decide whether or
1435 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

1445 * call.c (build_method_call): Ditto.

1464 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
1466 * decl2.c (finish_vtable_vardecl): Now set the
1467 interface/implementation of vtables on the first virtual function,
1468 if one exists, otherwise we use the old method. This is a major win
1469 in terms of cutting down the size of objects and executables in
1470 terms of text space and data space. Now most of the savings that
1471 #pragma interface/implementation gives is automatic in a fair number

1476 * decl.c (grokdeclarator): Discard the template parameters in a

1490 * parse.y: Add END_OF_LINE token.
1492 * lex.c (check_newline): Set linemode when we see a # directive, and
1493 unset it when we're done. Turn all 'return's into 'goto skipline'.
1494 Fix all uses of '\n', since we won't see it anymore. Put back the
1495 character we read before checking for a sysv or target pragma.
1496 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
1497 (handle_sysv_pragma): Don't look at the input stream; quit when we

1523 * class.c (instantiate_type): Change error message text.

1533 * typeck.c (convert_for_assignment): Initialize variable before use.

5334 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
5335 checking for one delete or the other.
5336 (lang_type): gets_new and gets_delete are now two bits long. The
5337 low bit is for the non-array version. Lose gets_placed_new.
5338 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
5339 delete defined by this class wants to know how much space it is
5341 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
5342 add a header containing the number of elements in the vector; i.e.
5343 when the elements need to be destroyed or vec delete wants to know
5345 * class.c (finish_struct_methods): Also check for overloading vec
5347 * call.c (build_method_call): Also delete second argument for vec
5350 * decl.c (grokdeclarator): Correct complaints again.
5351 (grokdeclarator): Fix segfault on null declarator.
5352 (decls_match): Also accept redeclaration with no arguments if both
5353 declarations were in C context. Bash TREE_TYPE (newdecl) here.
5354 (duplicate_decls): Instead of here.
5356 * parse.y (nested_name_specifier_1): Lose rules for dealing with
5357 syntax errors nicely, since they break parsing of 'const i;'.
5359 * decl.c (lookup_name): if (got_scope == current_class_type)
5360 val = IDENTIFIER_CLASS_VALUE (name).
5362 * search.c (lookup_nested_tag): Look in enclosing classes, too.
5364 * spew.c (yylex): Only look one character ahead when checking for a
5367 * lex.c (check_newline): Read first nonwhite char before
5368 incrementing lineno.
5370 * decl.c (grokdeclarator): Don't claim that typedefs are variables
5373 * parse.y: Divide up uses of unqualified_id into
5374 notype_unqualified_id and unqualified_id, so that TYPENAME can be
5375 used as an identifier after an object.
5377 * class.c (push_nested_class): Don't push into non-class scope.
5379 * decl.c (grokdeclarator): If an identifier could be a type
5380 conversion operator, but has no associated type, it's not a type
5381 conversion operator.
5383 * pt.c (unify): Check for equality of constants better.
5385 * decl.c (grokdeclarator): Don't complain about access decls.
5387 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
5389 * decl.c (grokdeclarator): pedwarn about data definitions without
5392 * parse.y (datadef): Don't pedwarn about decls without types here,
5393 since that is valid for functions.
5394 (fn.def2, component_decl): Support constructors with declmods again.
5395 (nomods_initdecls): For decls without any mods, so that we don't try
5396 to get declspecs from some arbitrary $0.
5398 * search.c (lookup_field): Use cp_error.
5400 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
5401 here; it breaks destructors for non-aggr types.
5403 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
5404 a type being defined, like the comment says.
5405 If got_scope is not an aggregate, just return NULL_TREE.
5407 * pt.c (create_nested_upt): Kung's code for creating types nested
5408 within uninstantiated templates now lives here (it used to live in
5409 hack_more_ids). It needs to be expanded.
5411 * parse.y: Stop calling see_typename so much.
5413 * decl.c (lookup_name): Deal with TTPs and UPTs.
5415 * lex.c (real_yylex): Don't set looking_for_typename just because we
5417 (dont_see_typename): #if 0 out.
5419 * spew.c (yylex): Increment looking_for_typename if the next
5420 character is SCOPE, rather than setting it to 1; this way, the value
5421 from seeing an aggr specifier will not be lost. This kinda relies
5422 on looking_for_typename never being < 0, which is now true.
5424 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
5426 (named_class_head_sans_basetype): Accept template types, too. Oops.
5428 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
5430 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
5432 * parse.y: Lose START_DECLARATOR.
5434 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
5437 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
5438 A::foo' syntax. Catch invalid scopes better.
5440 * parse.y, lex.c: lose TYPENAME_COLON.
5442 * decl2.c (groktypefield): #if 0 out.
5444 * decl.c (lookup_name): If the type denoted by got_scope is
5445 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
5447 * class.c (push_nested_class): Don't try to push into
5450 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
5452 * Makefile.in (stamp-parse): Update count of conflicts to 33.
5454 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
5456 A saner implementation of nested types that treats template types
5457 no differently from non-template types. There are still some
5458 shortcomings of our system; most notably, it is difficult to look
5459 for a nested type that is hidden by another name, because of the way
5460 we keep track of hidden types. But this shouldn't be a problem for
5461 just about anyone. Perhaps lookup_field should be fixed up a bit.
5463 * spew.c: Moved handling of nested types/scoping from the lexer
5464 into the parser. Removed variable template_type_seen_before_scope.
5465 Removed functions frob_identifier, hack_more_ids, and various cruft
5466 that was #if 0'd out in the past, reducing the size of the file from
5467 1146 lines to 450 lines. We can't quite do away with spew.c yet,
5468 though; we still need it for do_aggr () and checking for SCOPE after
5469 the current identifier. And setting lastiddecl.
5471 * parse.y: Moved handling of nested types/scoping from the lexer
5472 into the parser, using a new global variable `got_scope'. Reduced
5473 the number of states by 53. Implemented all uses of explicit global
5474 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
5475 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
5476 scoped_typename. Added nonterminals nested_type,
5477 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
5478 nested_name_specifier, global_scope, overqualified_id, type_name.
5479 Changed many others. Added 9 new reduce/reduce conflicts, which are
5480 nested type parallels of 9 that were already in the grammar for
5481 non-nested types. Eight of the now 33 conflicts should be removed
5482 in the process of resolving the late binding between variable and
5485 * gxxint.texi (Parser): Update.
5487 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
5489 * lex.h: Add decl for got_scope.
5491 * lex.c (see_typename): Claim to be the lexer when calling
5494 * decl.c (lookup_name): When called from the lexer, look at
5495 got_scope and looking_at_typename; otherwise don't.
5497 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
5499 31th Cygnus<->FSF merge.
5501 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
5503 * decl2.c (mark_vtable_entries): Call this to mark all the
5504 entries in the vtable addressable.
5505 (finish_decl_parsing): Handle SCOPE_REFs.
5507 * decl.c (decls_match): Always call compparms with strict == 1.
5508 Handle the special case of C function redecl here.
5509 (duplicate_decls): Only keep the old type if the new decl takes no
5512 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
5514 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
5516 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
5519 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5521 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
5522 ch-tree.h: Every place these functions were called, the result was
5523 immediately passed to expand_expr_stmt. Reduce redundancy by
5524 calling expand_expr_init *inside* these functions. These
5525 makes for a simpler interface, and we don't have to build
5526 compound expressions. Hence, rename these function to:
5527 expand_virtual_init and expand_vbase_vtables_init respectively.
5528 * init.c, decl.c: Change callers of these functions.
5529 * init.c, cp-tree.h (expand_virtual_init): Make static.
5531 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
5532 rather than DECL_SAVED_INSNS before emitting inlines.

5536 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
5538 * decl.c (duplicate_decls): If this is a new declaration of an
5539 extern "C" function, keep the type (for the argtypes).
5540 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
5541 (decls_match): Call compparms with a value of strict dependent on
5542 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
5544 * typeck.c (compparms): ... is only equivalent to non-promoting
5545 parms if we're not being strict.
5547 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
5549 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
5550 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
5552 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

5561 * cp-tree.h (memptr_type): New variable.
5562 * class.c (build_vtable_entry): Build thunk if necessary.
5563 * class.c (build_vfn_ref): If using thunks, don't need
5564 to add delta field from vtable (there is none!).
5565 * decl.c: Add memptr_type as well as vtable_entry_type.
5566 If using thunks, the latter is just ptr_type_node.
5567 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
5568 * decl2.c (finish_vtable_vardecl): Handle thunks.
5569 * expr.c (cplus_expand_expr): Support THUNK_DECL.
5571 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
5572 * decl.c (start_function): Set current_extern_inline based on
5573 DECL_THIS_EXTERN, not TREE_PUBLIC.
5574 * decl.c (finish_function): Call mark_inline_for_output if needed,
5576 Improve intelligence about when to emit inlines.
5577 * cp-tree.h (lang_decl_flags): New field saved_inline.
5578 * cp-tree.h (DECL_SAVED_INLINE): New macro.

5582 * decl2.c (mark_inline_for_output): Do nothing if
5583 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
5584 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
5585 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
5586 * decl2.c (finish_file): Writing out inlines later, so we can
5587 also handle the ones needed for vtbales.
5588 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
5590 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
5591 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
5592 instead. (The rationale is that these optimizations both break binary
5593 compatibility, but should become the default in a future release.)
5595 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
5597 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
5598 of a fndecl, as we might not be from that vfield.
5600 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
5602 * class.c (add_virtual_function): fix bug for pure virtual, so
5603 that DECL_VINDEX of the dummy decl copied won't be error.
5604 (see also Apr 4 change)
5606 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
5608 * typeck.c (c_expand_return): Before checking that we're not
5609 returning the address of a local, make sure it's a VAR_DECL.
5610 (And don't worry about it being a TREE_LIST.)
5612 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
5614 * parse.y (YYDEBUG): Always define.
5615 * lex.c (YYDEBUG): Ditto.
5617 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
5619 * class.c (finish_struct): backup out the change below, put the
5620 new change for the same purpose. The change below breaks code.
5622 * class.c (finish_struct): if pure virtual, copy node and make
5623 RTL point to abort, then put in virtual table.
5624 * decl2.c (grok_function_iit): reinstate Mar 31 change.
5626 Sat Apr 2 03:12:58 1994 Jason Merrill (jason@deneb.cygnus.com)
5628 * init.c (build_new): pedwarn about newing const and volatile
5631 * tree.c (get_identifier_list): Only do the special handling
5632 thing if we're dealing with the main variant of the record type.
5634 * cvt.c (convert_to_reference): When converting between
5635 compatible reference types, use the pointer conversion machinery.
5636 Don't just blindly overwrite the old type.
5638 Fri Apr 1 17:14:42 1994 Jason Merrill (jason@deneb.cygnus.com)
5640 * call.c (build_method_call): When looking at global functions,
5641 be sure to use instance_ptr for the first argument, not some version
5642 of it that has been cast to a base class. Also do this before
5643 comparing candidates.
5645 Thu Mar 31 19:50:35 1994 Jason Merrill (jason@deneb.cygnus.com)
5647 * call.c (build_method_call): Constructors can be called for

5670 Wed Mar 30 21:29:25 1994 Mike Stump <mrs@cygnus.com>
5672 Cures incorrect errors about pure virtuals in a class, when they
5673 have been overridden in a derived class.
5675 * search.c (get_abstract_virtuals): Reimplement.
5676 * search.c (get_abstract_virtuals_1): New routine.
5678 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)
5680 * pt.c (push_template_decls): Make the pushed level pseudo

5708 Cures calling a more base base class function, when a more derived
5709 base class member should be called in some MI situations.
5711 * search.c (make_binfo): Use more the more specialized base
5712 binfos from the binfo given as the second argument to make_binfo,

5753 when warning about re-friending.
5755 * pt.c (tsubst): Use comptypes rather than == to compare the
5756 types of the method as declared and as defined, since default
5757 parameters may be different.
5759 * call.c (build_method_call): Use brendan's candidate printing
5762 * decl.c (start_method): Methods defined in the class body are
5763 inline whether or not it's a template class.

5782 (start_function): Ditto.
5783 (push_overloaded_decl): Don't check for overloaded C functions.
5785 * *.c: Stop using DECL_OVERLOADED, it being archaic.
5786 TREE_OVERLOADED should probably go, too.
5788 Mon Mar 28 14:00:45 1994 Ron Guilmette (rfg@netcom.com)
5790 * typeck.c (comp_target_types): Call comp_target_parms with

5796 sections if we're compiling with -ansi or -pedantic.

5857 Wed Mar 23 00:46:24 1994 Mike Stump <mrs@cygnus.com>
5859 * class.c (modify_vtable_entries): Avoid running off the end of the
5860 virtuals list when processing a virtual destructor.

5889 instance, before fetching vtable pointer.
5890 * typeck.c (get_delta_difference): New routine.
5891 * typeck.c (build_ptrmemfunc): Revamp to handle casting better, also
5892 get vtable pointer out of right subobject.
5894 Tue Mar 22 17:56:48 1994 Mike Stump <mrs@cygnus.com>
5896 * search.c (get_binfo): Return NULL instead of aborting, when
5897 passed a UNION_TYPE.
5899 Tue Mar 22 12:44:54 1994 Jason Merrill (jason@deneb.cygnus.com)
5901 These patches implement handling of redefinition/redeclaration of
5904 * typeck.c (comptypes): Simplify. All TEMPLATE_TYPE_PARMs are
5905 considered compatible.
5907 * parse.y (template_def): Pass defn argument to end_template_decl.
5909 * pt.c (end_template_decl): Add defn argument. Check for
5910 redefinition. Simplify.
5912 * error.c (OB_UNPUT): New macro, to remove mistakes.
5913 (aggr_variety): Subroutine of dump_aggr_type.
5915 * decl.c (decls_match): Support templates.

5918 (pushdecl): Simplify.
5920 * cp-tree.h (DECL_TEMPLATE_MEMBERS): Use DECL_SIZE instead of
5923 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
5925 * error.c (dump_decl): Support class template decls.
5926 (dump_type): Don't adorn template type parms.
5928 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl
5929 if it was a definition.
5930 (redeclaration_error_message): Do the cp_error thang, and reject
5931 redefinition of templates.
5933 Mon Mar 21 19:36:06 1994 Per Bothner (bothner@kalessin.cygnus.com)
5935 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
5936 in FIELD context, when appropriate. Also,
5937 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
5938 Also, simplify check for bogus return specifiers.
5940 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
5942 * parse.y (after_type_declarator1): Expand type_quals.
5943 (notype_declarator1): Ditto.
5946 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
5948 * decl.c (grokdeclarator): Treat class-local typedefs like static
5949 members; i.e. 'typedef int f();' means that f is a function type,
5952 * parse.y (decl): Change direct_* back to *.
5953 (type_id): Change direct_abstract_declarator to absdcl.
5954 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.
5956 Fri Mar 18 12:47:59 1994 Jason Merrill (jason@deneb.cygnus.com)
5958 These two patches fix crashes on instantiating a template inside a
5959 function with C linkage or containing labels.
5961 * class.c (current_lang_stacksize): No longer static.
5963 * decl.c (struct saved_scope): Add lang_base, lang_stack,
5964 lang_name, lang_stacksize, and named_labels.
5965 (push_to_top_level): Save them.
5966 (pop_from_top_level): Restore them.
5968 * gxxint.texi (Parser): Update.
5970 These two patches finish moving the task of expr/declarator
5971 ambiguity resolution from the lexer to the parser, and add one more
5972 r/r conflict. START_DECLARATOR can now be nuked.
5974 * parse.y (decl): Add "direct_" in typespec X rules.
5975 (direct_declarator): New nonterminal for
5976 direct_after_type_declarator and direct_notype_declarator.

5979 (named_parm): Add typespec direct_declarator rule.
5981 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
5983 These two patches disable some excessive cleverness on the part of
5984 g++; a non-class declaration always hides a class declaration in the
5985 same scope, and g++ was trying to unhide it depending on the
5986 enclosing expression.
5988 * spew.c (arbitrate_lookup): #if 0 out.
5990 * decl.c (lookup_name): Never call arbitrate_lookup.
5992 * parse.y (complex_notype_declarator1): Add '*'
5993 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
5995 * parse.y (complex_direct_notype_declarator): Restore id_scope
5996 see_typename TYPENAME rule, remove all other rules beginning with
5998 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
6000 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
6002 These changes fix the compiler's handling of the functional cast/
6003 object declaration ambiguities in section 6.8 of the ARM. They also
6004 add 11 reduce/reduce conflicts. Sigh.
6006 * parse.y: Add precedence decls for OPERATOR and '~'.
6007 (notype_unqualified_id): New nonterminal, encompasses all of the
6008 ANSI unqualified-id nonterminal except TYPENAMEs.

6015 (complex_notype_declarator1): A notype_declarator that is not also
6016 an expr_or_declarator.
6017 (complex_direct_notype_declarator): A direct_notype_declarator that
6018 doesn't conflict with expr_or_declarator. Use
6019 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
6020 (functional_cast): New nonterminal, for the three functional cast
6021 rules. So that they can be moved after
6022 complex_direct_notype_declarator.
6023 (see_typename): Don't accept type_quals any more.
6025 * decl2.c (reparse_decl_as_expr): New function to deal with parse
6026 nodes for code like `int (*a)++;'.
6027 (reparse_decl_as_expr1): Recursive subroutine of the above.
6028 (finish_decl_parsing): New function to deal with parse nodes for
6029 code like `int (*a);'. See the difference?
6031 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
6033 These changes break binary compatibility in code with classes
6034 that use virtual bases.
6036 * search.c (dfs_get_vbase_types): Simplify and correct to make
6037 sure virtual bases are initialized in dfs ordering.
6038 * search.c (get_vbase_types): Simplify and make readable.
6040 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)
6042 * parse.y: s/ typename / type_id /g
6044 Wed Mar 16 17:42:52 1994 Kung Hsu (kung@mexican.cygnus.com)
6046 * parse.y (typespec): add SCOPE TYPENAME for global scoped
6049 * decl.c (complete_array_type): fix a bug that in -pendantic
6050 mode even there's no initializer, it will continue to build
6053 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
6055 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
6056 all of the scoped PTYPENAME rules.
6058 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
6060 * init.c (build_offset_ref): The value of A::typedef_name is
6061 always the TYPE_DECL, and never an error.
6063 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
6065 * search.c (get_base_distance_recursive): Two binfos can only
6066 represent the same object if they are both via_virtual.
6068 * class.c (finish_base_struct): Check vbases for ambiguity, too.
6070 * search.c (get_vbase_types): Accept binfo argument, too.
6072 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
6074 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
6075 initializer also, because back-end requires it.
6077 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
6079 * error.c (dump_expr): Support member functions (which show up as
6082 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>
6084 * init.c (build_new): Set the return type of multidimensional

6113 (complex_parmlist): Parmlists that are not also typenames.
6114 (parms_comma): Enabler.
6115 (named_parm): A parm that is not also a typename. Use declarator
6116 rather than dont_see_typename abs_or_notype_decl. Expand
6117 typed_declspecs inline.
6118 (abs_or_notype_decl): Lose.
6119 (dont_see_typename): Comment out.
6120 (bad_parm): Break out abs_or_notype_decl into two rules.

6124 * decl2.c (reparse_decl_as_casts): New function to change parse
6125 nodes for `(int)(int)(int)' from "function taking int and returning
6126 function taking int and returning function taking int" to "... cast
6127 to int, cast to int, cast to int".
6129 * decl2.c (reparse_decl_as_expr): Recursive function to change
6130 parse nodes for `A()()' from "function returning function returning
6131 A" to "A().operator()".
6133 * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
6134 `typespec fcast_or_absdcl' rule.
6135 (fcast_or_absdcl): New nonterminal to implement late reduction of

6142 Fri Mar 4 16:18:03 1994 Mike Stump <mrs@cygnus.com>
6144 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
6145 matches Section 5.5.
6147 Fri Mar 4 14:01:59 1994 Jason Merrill (jason@deneb.cygnus.com)
6149 * error.c (dump_type_prefix): Don't print basetype twice for

6154 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
6155 so that it is like setHandler(&A::handlerFn). Cures an `invalid
6156 lvalue in unary `&''.
6158 Fri Mar 4 11:15:59 1994 Jason Merrill (jason@deneb.cygnus.com)
6160 * gxxint.texi (Copying Objects): New section discussing default
6161 op= problems with virtual inheritance.
6163 * decl2.c (grokoptypename): Just does grokdeclarator and
6164 build_typename_overload, since the parser can't call grokdeclarator
6167 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
6168 and TREE_TYPE on generated identifiers.
6170 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.
6172 * parse.y (parm): Convert `const char *' to `__opPCc' here.

6184 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
6185 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid
6186 lvalue in unary `&''.

6197 rather than waiting until later.
6199 Wed Mar 2 14:12:23 1994 Jason Merrill (jason@deneb.cygnus.com)
6201 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather

6203 (typename): Expand empty option of (former) absdcl inline.
6204 (abs_or_notype_decl): Ditto.
6205 (absdcl): Lose empty rule.
6206 (conversion_declarator): New nonterminal for 'typename' of 'operator
6208 (operator_name): Use it instead of absdcl.

6213 directly. Add rules with reserved_typespecquals.
6214 (reserved_declspecs): Don't accept typespecqual_reserved at the
6215 beginning of the list. The typed_declspecs rule will deal with this
6217 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
6220 * parse.y (direct_notype_declarator,
6221 direct_after_type_declarator, direct_abstract_declarator): Split up
6222 the declarator1 nonterminals to match the draft standard and avoid
6224 (new_type_id, new_declarator, direct_new_declarator,
6225 new_member_declarator): New nonterminals to implement the subset of

6238 (get_decl_list): Use it.
6239 (list_hash_lookup_or_cons): Ditto.
6241 * parse.y (typed_declspecs, declmods): It's not necessary to hash
6242 the declspecs on class_obstack, so don't. This way typed_typespecs
6243 can reduce to typed_declspecs.
6245 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
6247 * cvt.c (build_up_reference): If we aren't checking visibility,
6248 also allow base->derived conversions.
6250 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
6252 * typeck.c (build_c_cast): Remove bogus hack when converting
6253 to a reference type.
6255 * cp-tree.h (lang_decl::vbase_init_list, DECL_VBASE_INIT_LIST):
6257 (lang_stype::methods, lang_decl::next_method): New fields.
6258 (CLASSTYPE_METHODS, DECL_NEXT_METHOD): New macros.
6259 * decl.c (duplicate_decls): Preserve DECL_NEXT_METHOD.
6261 * cp-tree.h, decl2.c (flag_vtable_hack): New flag.
6262 * decl2.c (finish_vtable_vardecl): If flag_vtable_hack,

6264 a non-inline virtual function to control emitting of vtables.
6265 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
6266 * search.c (build_vbase_vtables_init): Don't assemble_external
6267 (yet) if flag_vtable_hack.

6272 * parse.y (component_decl): Don't include "typed_declspecs
6273 declarator ';'" speedup, since it breaks enums.
6275 Fri Feb 25 15:43:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
6277 * class.c (finish_struct): Minor optimization for building

6284 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
6286 * lex.c (check_newline): #pragma interface can take a string
6287 argument, just like #pragma implementation. #pragma implementation
6288 checks for garbage on the line, line #pragma interface does. Main
6289 input files do not auto implement like named files, #pragma
6290 implementation must be used explicitly.
6292 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
6294 * parse.y (components): Handle list of one again.

6304 * Makefile.in (stamp-parse): Update expected conflict count.
6306 * parse.y (various): Replace "declmods declarator" with "declmods
6307 notype_declarator". The comment saying that "declmods declarator ';'"
6308 corresponds to "int i;" was wrong; it corresponds to "const i;".
6309 (component_decl): Add "typed_declspecs declarator ';'" rule; this
6310 *does* correspond to "int i;". Change "declmods components" to
6311 "declmods notype_components".
6312 (components): Don't deal with a list of one anymore.
6313 (notype_components): New nonterminal, corresponds to notype_declarator.

6319 (nontrivial_exprlist): New nonterminal: A list of at least two
6321 (nonnull_exprlist): Depend on nontrival_exprlist.
6322 Eliminates four reduce/reduce conflicts.
6324 (named_class_head): Move intermediate code block into separate
6325 nonterminal so that we can stick %prec EMPTY on it.
6327 Add more %prec EMPTY's to eliminate remaining shift/reduce
6330 (after_type_declarator): Add maybe_raises to fndecl rules.
6331 (after_type_declarator_no_typename): Remove.
6334 Document remaining reduce/reduce conflicts.
6336 Tue Feb 22 12:10:32 1994 Jason Merrill (jason@deneb.cygnus.com)
6338 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
6339 (TYPE_BINFO (type)) if we care about the path.
6341 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
6344 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>

6349 Sat Feb 19 01:27:14 1994 Jason Merrill (jason@deneb.cygnus.com)
6351 * parse.y: Eliminate 20 shift/reduce conflicts.
6353 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
6355 * pt.c (type_unification): Add subr argument; if set, it means
6356 that we are calling ourselves recursively, so a partial match is OK.
6357 (unify): Support pointers to methods and functions.
6358 (tsubst): Support method pointers.
6359 * decl.c (build_ptrmemfunc_type): No longer static, so that
6360 tsubst can get at it.
6362 * init.c (is_aggr_typedef): Pretend template type parms are
6364 * decl2.c (build_push_scope): If cname refers to a template type
6365 parm, just grin and nod.
6367 * call.c (build_overload_call_real): Pass subr argument to
6369 * pt.c (do_function_instantiation): Ditto.

6460 Remove NEW_CLASS_SCOPING, assuming it is always 1.

6957 current_class_type and current_function_decl is the most nested.
6958 (compute_access): Total overhaul to make it clearer and more

7302 to check if two fndecls are `the same'. Sometimes this routine can
7303 modify the main vtable, and normal should be 1, in that case, so use
7304 is_normal() to determine if this is the main vtable for the class.
7305 Don't recurse down virtual bases, as they are shared, and we take
7306 care of them elsewhere.

7308 vtable with the new virtual, don't do it again.
7309 * cp-class.c (finish_struct): Set CLASSTYPE_VFIELD_PARENT as

7350 (lang_decode_option): Set warn_return_type, not explicit_*, for
7351 -Wreturn-type and -Wall. This is what rest_of_compilation uses to
7352 decide if it should go into jump_optimize or not.

7354 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
7355 (finish_function): Also complain about no return in a non-void fn if
7356 we're being pedantic (don't rely on use of -Wreturn-type).

7414 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
7415 properly with the case where a class contains an object of an
7416 ambiguous base class which has a protected op=. Should be fixed
7417 when the access control code gets overhauled.
7418 (finish_struct_methods): Set TYPE_HAS_NONPUBLIC_* correctly.

7423 __FUNCTION__ and __PRETTY_FUNCTION__. Don't use lookup_name, to
7424 avoid the ambiguity problems that led to it being turned off in the
