            Bug ID: 34221
           Summary: Objective-C: annotation for copy-like methods
           Product: clang
           Version: unspecified
          Hardware: Macintosh
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com

                CC: llvm-bugs at lists.llvm.org

I wrote a deepMutableCopy method, and clang's static analyzer reports that I'm
autoreleasing objects too many times, because it doesn't know that my
deepMutableCopy method acts like copy, and needs a matching release or
autorelease. It would be nice if I could annotate this method so that clang
treats it like copy.
