— Add support for objc_msg_lookup_stret.
The assembly implementations of the lookup and forwarding still need to
be adjusted. Those just alias to the non-stret version for now so that
linking works, meaning the behaviour is still the same as without
support for objc_msg_lookup_stret for now. (user: js, size: 1371) [annotate] [blame] [check-ins using]
