+ (build_opfncall): Likewise.
+ * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
+ vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
+ * init.c (init_init_processing): Set up BIVN and BIVD.
+ (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
+ since it doesn't happen any more.
+ (build_new): Support vec new. Always call something.
+ (build_x_delete): Support vec delete.
+ (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,

+ new/delete.
+ (grokdeclarator): Also force vec new/delete to be static.

+ * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
+ checking for one delete or the other.
+ (lang_type): gets_new and gets_delete are now two bits long. The
+ low bit is for the non-array version. Lose gets_placed_new.
+ (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
+ delete defined by this class wants to know how much space it is
+ deleting.
+ (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
+ add a header containing the number of elements in the vector; i.e.
+ when the elements need to be destroyed or vec delete wants to know
+ the size.
+ * class.c (finish_struct_methods): Also check for overloading vec
+ delete.
+ * call.c (build_method_call): Also delete second argument for vec
+ delete.
+
+ * decl.c (grokdeclarator): Correct complaints again.
+ (grokdeclarator): Fix segfault on null declarator.

+ declarations were in C context. Bash TREE_TYPE (newdecl) here.
+ (duplicate_decls): Instead of here.
+
+ * parse.y (nested_name_specifier_1): Lose rules for dealing with

+
+ * decl.c (lookup_name): if (got_scope == current_class_type)
+ val = IDENTIFIER_CLASS_VALUE (name).
+
+ * search.c (lookup_nested_tag): Look in enclosing classes, too.

+
+ * decl.c (grokdeclarator): Don't claim that typedefs are variables
+ in warning.
+
+ * parse.y: Divide up uses of unqualified_id into
+ notype_unqualified_id and unqualified_id, so that TYPENAME can be
+ used as an identifier after an object.
+
+ * class.c (push_nested_class): Don't push into non-class scope.
+
+ * decl.c (grokdeclarator): If an identifier could be a type
+ conversion operator, but has no associated type, it's not a type
+ conversion operator.
+
+ * pt.c (unify): Check for equality of constants better.
+
+ * decl.c (grokdeclarator): Don't complain about access decls.
+
+Sun Apr 10 02:39:55 1994 Jason Merrill <jason@deneb.cygnus.com>
+
+ * decl.c (grokdeclarator): pedwarn about data definitions without
+ types here.
+
+ * parse.y (datadef): Don't pedwarn about decls without types here,
+ since that is valid for functions.
+ (fn.def2, component_decl): Support constructors with declmods again.
+ (nomods_initdecls): For decls without any mods, so that we don't try
+ to get declspecs from some arbitrary $0.
+
+ * search.c (lookup_field): Use cp_error.
+
+ * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
+ here; it breaks destructors for non-aggr types.
+
+ * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
+ a type being defined, like the comment says.
+ If got_scope is not an aggregate, just return NULL_TREE.
+
+ * pt.c (create_nested_upt): Kung's code for creating types nested
+ within uninstantiated templates now lives here (it used to live in
+ hack_more_ids). It needs to be expanded.
+
+ * parse.y: Stop calling see_typename so much.
+
+ * decl.c (lookup_name): Deal with TTPs and UPTs.
+
+ * lex.c (real_yylex): Don't set looking_for_typename just because we
+ saw a 'new'.
+ (dont_see_typename): #if 0 out.
+
+ * spew.c (yylex): Increment looking_for_typename if the next
+ character is SCOPE, rather than setting it to 1; this way, the value
+ from seeing an aggr specifier will not be lost. This kinda relies
+ on looking_for_typename never being < 0, which is now true.
+
+ * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
+ too.
+ (named_class_head_sans_basetype): Accept template types, too. Oops.
+
+Fri Apr 8 16:39:35 1994 Jason Merrill <jason@deneb.cygnus.com>
+
+ * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
+
+ * parse.y: Lose START_DECLARATOR.
+
+ * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
+ for a class.
+
+ * parse.y: Simplify fn.def2 and component_decl. Support 'enum
+ A::foo' syntax. Catch invalid scopes better.
+
+ * parse.y, lex.c: Lose TYPENAME_COLON.
+
+ * decl2.c (groktypefield): #if 0 out.
+
+ * decl.c (lookup_name): If the type denoted by got_scope is
+ currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
+
+ * class.c (push_nested_class): Don't try to push into
+ error_mark_node.
+
+Fri Apr 8 07:26:36 1994 Brendan Kehoe <brendan@lisa.cygnus.com>
+
+ * Makefile.in (stamp-parse): Update count of conflicts to 33.
+
+Thu Apr 7 17:47:53 1994 Jason Merrill <jason@deneb.cygnus.com>
+
+ A saner implementation of nested types that treats template types
+ no differently from non-template types. There are still some
+ shortcomings of our system; most notably, it is difficult to look
+ for a nested type that is hidden by another name, because of the way
+ we keep track of hidden types. But this shouldn't be a problem for
+ just about anyone. Perhaps lookup_field should be fixed up a bit.
+
+ * spew.c: Moved handling of nested types/scoping from the lexer
+ into the parser. Removed variable template_type_seen_before_scope.
+ Removed functions frob_identifier, hack_more_ids, and various cruft
+ that was #if 0'd out in the past, reducing the size of the file from
+ 1146 lines to 450 lines. We can't quite do away with spew.c yet,
+ though; we still need it for do_aggr () and checking for SCOPE after
+ the current identifier. And setting lastiddecl.
+
+ * parse.y: Moved handling of nested types/scoping from the lexer
+ into the parser, using a new global variable `got_scope'. Reduced
+ the number of states by 53. Implemented all uses of explicit global
+ scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
+ nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
+ scoped_typename. Added nonterminals nested_type,
+ qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
+ nested_name_specifier, global_scope, overqualified_id, type_name.
+ Changed many others. Added 9 new reduce/reduce conflicts, which are
+ nested type parallels of 9 that were already in the grammar for
+ non-nested types. Eight of the now 33 conflicts should be removed
+ in the process of resolving the late binding between variable and
+ function decls.
+
+ * gxxint.texi (Parser): Update.
+
+ * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
+
+ * lex.h: Add decl for got_scope.
+
+ * lex.c (see_typename): Claim to be the lexer when calling
+ lookup_name.
+
+ * decl.c (lookup_name): When called from the lexer, look at
+ got_scope and looking_at_typename; otherwise don't.
+
+Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>

+ 31th Cygnus<->FSF merge.

+Wed Apr 6 16:05:10 1994 Per Bothner <bothner@kalessin.cygnus.com>
+
+ * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
+ ch-tree.h: Every place these functions were called, the result was
+ immediately passed to expand_expr_stmt. Reduce redundancy by
+ calling expand_expr_init *inside* these functions. These
+ makes for a simpler interface, and we don't have to build
+ compound expressions. Hence, rename these function to:
+ expand_virtual_init and expand_vbase_vtables_init respectively.
+ * init.c, decl.c: Change callers of these functions.
+ * init.c, cp-tree.h (expand_virtual_init): Make static.
+

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

+ the value of strict_prototypes for DECL_LANGUAGE (oldecl).
+
+ * typeck.c (compparms): ... is only equivalent to non-promoting
+ parms if we're not being strict.
+
+ * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
+
+ * decl.c (init_decl_processing): if (flag_ansi || pedantic)

+ * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.

+ * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.

+
+ * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
+ and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
+ instead. (The rationale is that these optimizations both break binary
+ compatibility, but should become the default in a future release.)
+
+Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
+
+ * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT

+
+ * class.c (add_virtual_function): Fix bug for pure virtual, so

+ (see also Apr 4 change)
+
+Tue Apr 5 17:23:45 1994 Per Bothner <bothner@kalessin.cygnus.com>
+
+ * typeck.c (c_expand_return): Before checking that we're not

+Sat Mar 19 01:05:17 1994 Jason Merrill <jason@deneb.cygnus.com>

+
+Thu Mar 17 17:30:01 1994 Jason Merrill <jason@deneb.cygnus.com>
+
+ These changes fix the compiler's handling of the functional cast/
+ object declaration ambiguities in section 6.8 of the ARM. They also
+ add 11 reduce/reduce conflicts. Sigh.
+
+ * parse.y: Add precedence decls for OPERATOR and '~'.
+ (notype_unqualified_id): New nonterminal, encompasses all of the
+ ANSI unqualified-id nonterminal except TYPENAMEs.

+ (decl): Add typespec initdecls ';' and typespec declarator ';'
+ rules.
+ (initdcl0): Deal with the above.

+ an expr_or_declarator.
+ (complex_direct_notype_declarator): A direct_notype_declarator that
+ doesn't conflict with expr_or_declarator. Use
+ notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
+ (functional_cast): New nonterminal, for the three functional cast
+ rules. So that they can be moved after
+ complex_direct_notype_declarator.
+ (see_typename): Don't accept type_quals any more.
+
+ * decl2.c (reparse_decl_as_expr): New function to deal with parse
+ nodes for code like `int (*a)++;'.
+ (reparse_decl_as_expr1): Recursive subroutine of the above.
+ (finish_decl_parsing): New function to deal with parse nodes for
+ code like `int (*a);'. See the difference?
+
+Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
+
+ These changes break binary compatibility in code with classes
+ that use virtual bases.
+
+ * search.c (dfs_get_vbase_types): Simplify and correct to make
+ sure virtual bases are initialized in dfs ordering.
+ * search.c (get_vbase_types): Simplify and make readable.
+

+
+ * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove

+
+Tue Mar 15 20:02:35 1994 Jason Merrill <jason@deneb.cygnus.com>
+
+ * search.c (get_base_distance_recursive): Two binfos can only

+
+ * class.c (finish_base_struct): Check vbases for ambiguity, too.
+
+ * search.c (get_vbase_types): Accept binfo argument, too.

+Tue Mar 15 19:22:05 1994 Kung Hsu <kung@mexican.cygnus.com>
