* Add a 'unique' method to SkRefCnt, document the usage, and add support.Gravatar bungeman@google.com2013-07-19
| | | | | | | | | | | | | | | | | | std::shared_ptr has a method called 'unique' which captures the concept that a reference count of 1 is special, and can be used to optimize copy on write. It also has some undocumented need for memory barriers in certain situations and those needs are documented here. The motivation for looking into this is crbug.com/258499 . The use of the reference count in this manner is a benign race with both ref() and unref(). By introducing sk_atomic_unprotected_read, it is possible for Chromium to annotate this read to tell ThreadSanitizer that this is known.
