URL: http://llvm.org/viewvc/llvm-project?rev=162220&view=rev
Log:
Code-complete 'weak' for properties under ARC-with-weak-references (or GC)
Also, suggest 'readonly' even if the property has been given an ownership
attribute ('strong', 'weak', etc). This is used when properties are declared
readonly in the public interface but readwrite in a class extension.
