2009-05-04Remove unnecessary push_back (at least, I think it's unnecessary); Eli Friedman
hopefully, this fixes PR4144 without any regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70823 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04Don't allow clients to traverse into superclass synthesized propertiesDaniel Dunbar
via CollectObjCIvars. - In places where we need them, we should have the implementation and access the properties through it. This is a fairly substantial functionality change: 1. @encode no longer encodes synthesized ivars, ever. 2. The ivar layout bitmap no longer encodes information for synthesized ivars in superclasses. Well, actually I had already broken that, but it is intentional now. We are now differing substantially from llvm-gcc and gcc here. However, in my opinion this fundamentally *must* work if non-fragile classes are to work. Without this change, the result of @encode and the ivar layout depend on the order that the implementation is seen in a file (if it is in the same file with its superclass). Since both scenarios should work the same, our behavior is now consistent with gcc behavior as if an implementation is never seen following an implementation of its superclass. Note that #2 is only a functionality change when (A) an implementation appears in the same translation unit with the implementation of its superclass, and (B) the superclass has synthesized ivars. My belief is that this situation does not occur in practice. I am not yet sure of the role/semantics of @encode when synthesized ivars are present... it's use is fairly unsound in a non-fragile world. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70822 91177308-0d34-0410-b5e6-96231b3b80d8
