Thanks Doug for your reply.

Is there a bug for this?  I searched but could not find one.  I filed
<rdar://problem/8107317> after WWDC10 but I'd like to have a bug in the
public llvm.org database too.

As more and more Objective-C features _require_ clang[1], Mac developers
will be forced to choose between these nice new features and being able
to measure code coverage.  I'm not looking forward to that choice. :(
