Fixed bug in loading of categories under certain special circumstances

[thirdparty/gcc.git] / libobjc / ChangeLog

Mon Dec 17 17:02:12 2001  Nicola Pero  <nicola@brainstorm.co.uk>

	* init.c (__objc_exec_class): Fixed bug in the loop on unclaimed
	categories - when an unclaimed category was found, the loop was
	doing two steps forward instead of one, so that in certain cases
	it was failing to properly load all the categories.  (Reported
	with fix by Alexander Malmberg <alexander@malmberg.org>).

2001-11-14  Aldy Hernandez  <aldyh@redhat.com>

        * encoding.c: Add target_flags.

2001-11-07  Aldy Hernandez  <aldyh@redhat.com>

	 * objc/objc-api.h (_C_VECTOR): New.

	 * encoding.c (VECTOR_TYPE): New.

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_table_insert.  (objc_lookup_class), (objc_get_class): Do not
        assert the existence of the table; do not lock the runtime; use
        class_table_get_safe.  (objc_next_class): Use class_table_next.
        (__objc_resolve_class_links): Use class_table_next.
        (class_pose_as): Use class_table_replace.

2001-09-10  Ovidiu Predescu  <ovidiu@cup.hp.com>

	* gc.c: Removed the DEBUG declaration.

Wed Jul 18 12:48:56 2001  Nicola Pero  <n.pero@mi.flashnet.it>

	* thr.c (objc_mutex_lock): Invoke __objc_thread_id directly,
	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>

	* configure.in (AC_EXEEXT): Work around in case it expands to
	nothing, as in autoconf 2.50.
	* acinclude.m4: Likewise.
	* configure: Rebuilt.

2001-06-08  Nicola Pero  <n.pero@mi.flashnet.it>

	* THREADS: Explain that when we compile libobjc inside GCC, we
	always use thr-objc.c as a backend, which uses GCC's thread code.

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.
