	* cp-tree.h (VTABLE_NAME_FORMAT):  If flag_vtable_thunks,
	use "VT" rather than "vt" due to binary incompatibility.

Thu Apr 14 07:15:11 1994  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* decl.c (push_overloaded_decl): Avoid giving errors about

	* cvt.c (convert_to_reference): Warn about casting pointer type to

	* 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.
	(grok_op_properties): Note presence of vec new/delete, and play with
	their args.  If vec delete takes the optional size_t argument, set
	TYPE_VEC_DELETE_TAKES_SIZE.
	* 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
	syntax errors nicely, since they break parsing of 'const i;'.

	* 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.

	* spew.c (yylex): Only look one character ahead when checking for a
	SCOPE.

	* lex.c (check_newline): Read first nonwhite char before
	incrementing lineno.

	* 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)

	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.

Thu Apr  7 17:47:53 1994  Jason Merrill  (jason@deneb.cygnus.com)

	entries in the vtable addressable.
	(finish_decl_parsing): Handle SCOPE_REFs.

	* decl.c (decls_match): Always call compparms with strict == 1.
	Handle the special case of C function redecl here.
	(duplicate_decls): Only keep the old type if the new decl takes no
	arguments.

	* typeck.c (compparms): Also allow t1 to be ... if strict == 0.

Thu Apr  7 16:17:50 1994  Mike Stump  (mrs@cygnus.com)

	17:48:41.

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.

Sat Mar 19 01:05:17 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

	(notype_unqualified_id): New nonterminal, encompasses all of the
	ANSI unqualified-id nonterminal except TYPENAMEs.
	(expr_or_declarator): New nonterminal to delay parsing of code like
	`int (*a)'.
	(primary): Use notype_unqualified_id.

	rules.
	(initdcl0): Deal with the above.
	(complex_notype_declarator1): A notype_declarator that is not also
	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?

	default index.

Wed Mar 16 17:43:07 1994  Jason Merrill  (jason@deneb.cygnus.com)

	* cvt.c (build_up_reference): If we aren't checking visibility,

	* Makefile.in (stamp-parse): Update expected conflict count.

	* parse.y (various): Replace "declmods declarator" with "declmods
	notype_declarator".  The comment saying that "declmods declarator ';'"
	corresponds to "int i;" was wrong; it corresponds to "const i;".
	(component_decl): Add "typed_declspecs declarator ';'" rule; this
	*does* correspond to "int i;".  Change "declmods components" to
	"declmods notype_components".

	conflicts.

	(after_type_declarator): Add maybe_raises to fndecl rules.
	(after_type_declarator_no_typename): Remove.
	For correctness.

Fri Feb 18 11:49:42 1994  Jason Merrill  (jason@deneb.cygnus.com)

	* pt.c (type_unification): Add subr argument; if set, it means

	tsubst can get at it.

	that provides the most access.
	(get_base_distance): Ditto.

	* parse.y (explicit_instantiation): Syntax is 'template class
	A<int>', not 'template A<int>'.

	* decl.c (build_ptrmemfunc_type): Make sure that the pmf type
	goes onto the same obstack as its target type.

Wed Feb 16 00:34:46 1994  Jason Merrill  (jason@deneb.cygnus.com)

	* cvt.c (convert_to_reference): If converting via constructor
	on local level, go back to build_cplus_new approach.

	* tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
	to error_mark_node to prevent expand_expr from building a cleanup
	for this variable.

	* lex.c (default_assign_ref_body): Return *this from the memcpy
	version, too.

	* decl.c (grok_reference_init): Just return if called with
	error_mark_node, don't worry about initializing non-const reference
	with temporary.

	* cvt.c (convert_to_reference): Do the right thing for
	non-aggregate reference conversions, pedwarn when generating a
	non-const reference to a temporary.

	* class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
	TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
	again.

Tue Feb 15 19:47:19 1994  Jason Merrill  (jason@deneb.cygnus.com)

	* decl.c (grok_reference_init): Pawn off a lot of the work on
	convert_to_reference.  Generally do the right thing.

	* cvt.c (convert_to_reference): Conform to the initial comment;
	i.e. don't create temps if decl != error_mark_node.  Handle
	cleanups better for temps that do get created.  Don't pretend
	that we can use an 'A' to initialize a 'const double &' just by
	tacking on a NOP_EXPR.  Support LOOKUP_SPECULATIVELY.

	* call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on
	constructor calls.

	const reference from constant expression.

Mon Feb 14 11:31:31 1994  Per Bothner  (bothner@kalessin.cygnus.com)

	* cp-tree.h, decl.c (set_identifier_local_value):  Deleted function.
	* decl.c (pushdecl):  Define decl in correct binding_level
	(which isn't always the inner_binding_level).

	* cvt.c (build_up_reference):  Don't ever call expand_aggr_init.
	It's ugly, and I don't think it's the right thing to do.

	* cp-tree.h, class.c, decl.c, decl2.c, sp/search.c: 
	Remove NEW_CLASS_SCOPING, assuming it is always 1.
	* decl.c (pop_decl_level):  Removed; manually inlined.

	    with destructor names when either NO_DOLLAR_IN_LABEL or

	initialize a type that needs constructing with a CONSTRUCTOR.

	* init.c (expand_aggr_init_1, CONSTRUCTOR case): If
	store_init_value fails, build and expand an INIT_EXPR.  If

	* init.c (resolve_offset_ref): Make sure we first convert to
	intermediate type, if given, when dealing with members off `this'.

Thu Feb 10 21:49:35 1994  Mike Stump  (mrs@cygnus.com)

	* class.c (modify_other_vtable_entries): Use get_binfo, instead
	of binfo_value.  Solves problem with compiler giving a `base class

	base class.

	* init.c (build_new): Deal with `new double (1)'.

	* class.c (finish_struct): TYPE_HAS_COMPLEX_*_REF are supersets of

	* decl.c (duplicate_decls): Propagate access decls.

	* typeck2.c (process_init_constructor): Accept empty_init_node
	for initializing unions.

	vtable name.)
	* cp-class.c (modify_other_vtable_entries): Use DECL_ASSEMBLER_NAME
	to check if two fndecls are `the same'.  Sometimes this routine can
	modify the main vtable, and normal should be 1, in that case, so use

	* cp-decl2.c (explicit_warn_return_type): Deleted variable.
	(lang_decode_option): Set warn_return_type, not explicit_*, for
	-Wreturn-type and -Wall.  This is what rest_of_compilation uses to
	decide if it should go into jump_optimize or not.
	* cp-tree.h (explicit_warn_return_type): Deleted.
	* cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
	(finish_function): Also complain about no return in a non-void fn if
	we're being pedantic (don't rely on use of -Wreturn-type).

	to see if something is a method.

	update cant_synth_*, propagate TYPE_GETS_ASSIGN_REF.
	(finish_struct): Add decls for cant_synth_*, no_const_asn_ref, and
	initialize them properly.  Set no_const_asn_ref properly.  Set
	cant_synth_* in some of the situations where they should be set.
	Propagate TYPE_GETS_ASSIGN_REF.  Use cant_synth_copy_ctor.  Add call
	to cons_up_default_function for operator=.

	* cp-cvt.c (convert_force): Add code to perform casting of pointer
	to member function types.
	* cp-typeck.c (build_ptrmemfunc): Add FORCE parameter to indicate
	when the conversion should be done, regardless.
	* cp-tree.h (build_ptrmemfunc): Ditto.
	* cp-type2.c (digest_init): Ditto.
	* cp-typeck.c (convert_for_assignment): Ditto.

Tue Nov 23 18:06:58 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-error.c (dump_expr): Do the right thing for variables of
	reference type.

	* cp-decl.c (grok_op_properties): Set TYPE_HAS_ASSIGN_REF
	and its kin properly.
	(xref_tag): Propagate TYPE_GETS_ASSIGN_REF.

Tue Nov 23 12:26:13 1993  Mike Stump  (mrs@cygnus.com)

	* cp-method.c (build_opfncall): Don't count pointer to member
	functions as aggregates here, as we don't want to look up methods in
	them.  The compiler would core dump if we did, as they don't have
	normal names.
	* cp-typeck.c (build_indirect_ref): Improve wording on error
	message.

Mon Nov 22 14:22:23 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-decl.c (grok_op_properties): Allow operator?: with pedwarn
	(since it's supported in other compiler bits).

	* cp-method.c (report_type_mismatch): Use cp_error; ignore err_name
	argument.

	* cp-error.c (dump_function_decl): Don't print return type for
	constructors and destructors.

	* cp-cvt.c (cp_convert_to_pointer): Import code from
	convert_to_pointer so we can return error_mark_node in the case of an
	error, and to allow more meaningful error messages.
	(build_type_conversion): Don't go through void* when trying
	to convert to a pointer type.

	* cp-decl.c (grokfndecl): Move call to grok_op_properties back
	after grokclassfn so that it's dealing with the right decl.
        (grok_op_properties): Don't assert !methodp for op new and op delete.

	* cp-init.c (build_delete): Don't use TYPE_BUILT_IN (there are now
	no uses of it in the compiler).

	* cp-call.c (build_scoped_method_call): Fix for destructors of simple
	types.
	(build_method_call): Ditto.

Fri Nov 19 12:59:38 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-tree.c (count_functions): Abstraction function.

	* cp-call.c (build_overload_call_real): Deal with new overloading
	properly, remove dead code.

	* gcc.c (default_compilers): Generate and use .ii files in the
	intermediate stage of compiling C++ source.

Fri Nov 19 11:26:09 1993  Jim Wilson  (wilson@sphagnum.cygnus.com)

	* cp-expr.c (cplus_expand_expr): Make call_target a valid memory
	address before using it, so it can be later safely compared.

Fri Nov 12 15:30:27 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-pt.c (tsubst): Deal with new overloading.

	* cp-typeck.c (fntype_p): is the arg function type?
	(comp_target_parms): pedwarn on conversion from (anything) to (...).
	(build_x_function_call): Deal with new overloading.

	* cp-tree.c (decl_list_length): Deal with new overloading.
	(decl_value_member): Like value_member, but for DECL_CHAINs.

	* cp-decl.c (duplicate_decls): Deal with new overloading.
	(start_decl): Ditto.

	* cp-class.c (instantiate_type): Deal with new overloading.

	* cp-call.c (convert_harshness_ansi): Deal with new overloading.
	(convert_harshness_old): Deal with new overloading.
	(build_overload_call_real): Ditto.

Mon Nov  8 13:50:49 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
	if unambiguous, NULL_TREE otherwise.
	(get_first_fn): Returns the first appropriate FUNCTION_DECL.
	(is_overloaded_fn): Returns whether or not the passed tree is
	a function or list of functions.

	* cp-init.c (init_init_processing): use `get_first_fn' to find
	the FUNCTION_DEFN for new and delete.

	* cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
	code size in half (I spit on special cases).

Tue Sep  7 20:03:33 1993  Jason Merrill  (jason@deneb.cygnus.com)

	* cp-decl.c: Allow references and template type parameters as well
