llvm document on ARC
Automatic Reference Counting implements automatic memory management for Objective-C objects and blocks,freeing the programmer from the need explicitly insert retains and releases. It does not provide a cycle collector; users must explicitly manage lifetime instead.

A retainable object pointer (or retainable pointer) is a value of a retainable object pointer type (retainable type). There are three kinds of retainable object pointer types:
- block pointers (formed by applying the caret (^) declarator sigil to a function type)
- Objective-C object pointers (id,Class,NSFoo*,etc.)
- typedefs marked with __attribute__((NSObject))
Other pointer types,such as int* and CFStringRef,are not subject to ARC’s semantics and restrictions.
