Hi Everyone,
I've fixed a few clang bugs this week, and it's now capable of
compiling the entire Étoilé tree with both the GCC-compatible and non-
fragile ABIs. If anyone wants to play with it, grab the latest svn.
You need libobjc2 from GNUstep svn to use the new ABI and you need to
add -fobjc-nonfragile-abi to your OBJCFLAGS. This lets you hide
instance variables away from public headers. This is needed for the
fast forwarding (-forwardingProxyForSelector:) and non-fragile ivars
to work.
With both ABIs you get fast enumeration and declared properties. Both
of these require either libobjc2 or the ObjectiveC2 framework from
Étoilé.
You do NOT need to compile GNUstep with clang, and you can mix the two
ABIs in the same program, although if you subclass a non-fragile ABI
class with a fragile ABI class then things will break.
