I'm building a universal app to run on 10.3.9 and later. The new
fast obj-c dispatch option for Tiger seems like a good thing. I
can't use it for my PPC code since it must run on Panther, but
there doesn't seem to be any reason not to use it for Intel since
that requires Tiger. Is there any way to enable this for the Intel
compiler but not for the PPC compiler?
Is there a significant advantage to using this option? I can't
find any documentation on it?
There is no accelerated Obj-C dispatch on Intel, so there's no
advantage to turning it on. Testing showed that implementing it
would not have resulted in any performance improvement there because
the standard objc_msgSend implementation was fast enough.
