Mon Oct 29 21:29:21 2001  Nicola Pero  <n.pero@mi.flashnet.it>

	* class.c: Rewritten the class table to use optimized, lock-free
	lookup.  This more than doubles the speed of class method
	invocations.  (class_table_setup), (class_table_insert),
	(class_table_replace), (class_table_get_safe),
	(class_table_next), (class_table_print),
	(class_table_print_histogram): New functions.
	(__objc_init_class_tables): Use class_table_setup.
	(__objc_add_class_to_hash): Use class_table_get_safe and

	(class_pose_as): Use class_table_replace.

	rather than through objc_thread_id, to save a function call.
	(objc_mutex_trylock, objc_mutex_unlock, objc_condition_wait):
	Ditto.

Mon Jul 16 12:15:00 2001  Nicola Pero  <n.pero@mi.flashnet.it>

	* objc/objc-api.h (object_is_class): Fixed - buggy code was trying
	to cast an id to a Class, which can not be done.  Make the check
	by using CLS_ISMETA on the class pointer instead.
	(object_is_meta_class): Similar fix.

2001-06-09  Alexandre Oliva  <aoliva@redhat.com>, Stephen L Moshier  <moshier@mediaone.net>

2001-06-06  Richard Frith-Macdonald  <rrfm@gnu.org>

	* init.c (__objc_send_message_in_list): When setting a new entry
	in __objc_load_methods use the method IMP as key, but check to see
	if the method is in the hashtable by looking at the IMP also.
	Also ... call the method after adding it to the hashtable rather
	than before ... thus preventing an obscure possibility of infinite
	recursion if a +load method itself loads a subclass.

2001-05-25  Ovidiu Predescu  <ovidiu@cup.hp.com>

	* init.c (__objc_send_message_in_list): When setting a new entry
	in __objc_load_methods use the method name as key, not the method
	IMP (reported by Richard Frith-Macdonald <richard@brainstorm.co.uk>).

Wed Jan  3 00:49:10 2001  Ovidiu Predescu  <ovidiu@cup.hp.com>

	* sendmsg.c: Added __objc_msg_forward, a hook that allows external
	libraries to provide a function that returns the real forwarding
	function. This can alleviate problems __builtin_apply() and
	friends have on various platforms. (Solution suggested by Helge
	Hess.)

	* objc/objc-api.h: Define __objc_msg_forward.

	* sendmsg.c: Define gen_rtx_REG.
