Bug #: 50428
Summary: Consider changing semantics of +initialize so that it
is inherited
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libobjc
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: nicola@gcc.gnu.org
One of the remaining differences between the GNU Objective-C runtime and the
Apple one is that +initialize methods are inherited in the Apple runtime but
not in the GNU one.
To reduce differences, we could change the GNU runtime to inherit them too.
This
is a change in behaviour and should be clearly advertised in the release notes.
Thanks

We should also document +initialize in the GCC Manual, no matter if we keep the
existing semantics or change them.
Thanks

* sendmsg.c (__objc_send_initialize): If a class does not have an
+initialize method, search for an +initialize method in the
superclass and in the ancestor classes and execute the first one
that is found. This makes the GNU runtime behave in the same way
as the Apple/NeXT runtime with respect to +initialize methods and
subclassing.
