1 Mon Oct 29 21:29:21 2001 Nicola Pero <n.pero@mi.flashnet.it>
3 * class.c: Rewritten the class table to use optimized, lock-free
4 lookup. This more than doubles the speed of class method
5 invocations. (class_table_setup), (class_table_insert),
6 (class_table_replace), (class_table_get_safe),
7 (class_table_next), (class_table_print),
8 (class_table_print_histogram): New functions.
9 (__objc_init_class_tables): Use class_table_setup.
10 (__objc_add_class_to_hash): Use class_table_get_safe and
11 class_table_insert. (objc_lookup_class), (objc_get_class): Do not
12 assert the existence of the table; do not lock the runtime; use
13 class_table_get_safe. (objc_next_class): Use class_table_next.
14 (__objc_resolve_class_links): Use class_table_next.
15 (class_pose_as): Use class_table_replace.
17 2001-09-10 Ovidiu Predescu <ovidiu@cup.hp.com>
19 * gc.c: Removed the DEBUG declaration.
21 Wed Jul 18 12:48:56 2001 Nicola Pero <n.pero@mi.flashnet.it>
23 * thr.c (objc_mutex_lock): Invoke __objc_thread_id directly,
24 rather than through objc_thread_id, to save a function call.
25 (objc_mutex_trylock, objc_mutex_unlock, objc_condition_wait):
28 Mon Jul 16 12:15:00 2001 Nicola Pero <n.pero@mi.flashnet.it>
30 * objc/objc-api.h (object_is_class): Fixed - buggy code was trying
31 to cast an id to a Class, which can not be done. Make the check
32 by using CLS_ISMETA on the class pointer instead.
33 (object_is_meta_class): Similar fix.
35 2001-06-09 Alexandre Oliva <aoliva@redhat.com>, Stephen L Moshier <moshier@mediaone.net>

42 2001-06-08 Nicola Pero <n.pero@mi.flashnet.it>
44 * THREADS: Explain that when we compile libobjc inside GCC, we
45 always use thr-objc.c as a backend, which uses GCC's thread code.
47 2001-06-06 Richard Frith-Macdonald <rrfm@gnu.org>
49 * init.c (__objc_send_message_in_list): When setting a new entry
50 in __objc_load_methods use the method IMP as key, but check to see
51 if the method is in the hashtable by looking at the IMP also.
52 Also ... call the method after adding it to the hashtable rather
53 than before ... thus preventing an obscure possibility of infinite
54 recursion if a +load method itself loads a subclass.
56 2001-05-25 Ovidiu Predescu <ovidiu@cup.hp.com>
58 * init.c (__objc_send_message_in_list): When setting a new entry
59 in __objc_load_methods use the method name as key, not the method
60 IMP (reported by Richard Frith-Macdonald <richard@brainstorm.co.uk>).

123 Wed Jan 3 00:49:10 2001 Ovidiu Predescu <ovidiu@cup.hp.com>
125 * sendmsg.c: Added __objc_msg_forward, a hook that allows external
126 libraries to provide a function that returns the real forwarding
127 function. This can alleviate problems __builtin_apply() and
128 friends have on various platforms. (Solution suggested by Helge
131 * objc/objc-api.h: Define __objc_msg_forward.
133 * sendmsg.c: Define gen_rtx_REG.
