2             Richard Henderson  <rth@redhat.com>
4         * exception.c (__gnu_objc_personality_seh0): New function.
6 2012-05-16  H.J. Lu  <hongjiu.lu@intel.com>

35 2011-10-09  Nicola Pero  <nicola.pero@meta-innovation.com>
37         PR libobjc/49883
38         * init.c (__objc_exec_class): Work around a bug in clang's code
39         generation.  Clang sets the class->info field to values different
40         from 0x1 or 0x2 (the only allowed values in the traditional GNU
41         Objective-C runtime ABI) to store some additional information, but
42         this breaks backwards compatibility.  Wipe out all the bits in the
43         fields other than the first two upon loading a class.
45 2011-10-09  Nicola Pero  <nicola.pero@meta-innovation.com>
47         * class.c (objc_lookup_class): Added back for compatibility with

54         * sendmsg.c (__objc_send_initialize): If a class does not have an
55         +initialize method, search for an +initialize method in the
56         superclass and in the ancestor classes and execute the first one
57         that is found.  This makes the GNU runtime behave in the same way
58         as the Apple/NeXT runtime with respect to +initialize methods and
59         subclassing.
61 2011-08-06  Nicola Pero  <nicola.pero@meta-innovation.com>
63         PR libobjc/50002
64         * class.c (__objc_update_classes_with_methods): Iterate over meta
65         classes as well as normal classes when refreshing the method

68 2011-08-06  Nicola Pero  <nicola.pero@meta-innovation.com>
70         * class.c (class_getSuperclass): Fixed to work with meta classes
71         still in construction too.

87         $(srcdir)/$(MULTISRCTOP)../libgcc.

2905         Ditto.
2907 Mon Jul 16 12:15:00 2001  Nicola Pero  <n.pero@mi.flashnet.it>
2909         * objc/objc-api.h (object_is_class): Fixed - buggy code was trying
2910         to cast an id to a Class, which can not be done.  Make the check
2911         by using CLS_ISMETA on the class pointer instead.
2912         (object_is_meta_class): Similar fix.

2926 2001-06-06  Richard Frith-Macdonald  <rrfm@gnu.org>
2928         * init.c (__objc_send_message_in_list): When setting a new entry

2930         if the method is in the hashtable by looking at the IMP also.
2931         Also ... call the method after adding it to the hashtable rather
2932         than before ... thus preventing an obscure possibility of infinite
2933         recursion if a +load method itself loads a subclass.

2937         * init.c (__objc_send_message_in_list): When setting a new entry

3005         libraries to provide a function that returns the real forwarding
3006         function. This can alleviate problems __builtin_apply() and
