Enumerators
| Name | Value | Comment |
|---|---|---|
| S_None | 0 | |
| S_Retain | 1 | objc_retain(x). |
| S_CanRelease | 2 | foo(x) -- x could possibly see a ref count decrement. |
| S_Use | 3 | any use of x. |
| S_Stop | 4 | like S_Release, but code motion is stopped. |
| S_Release | 5 | objc_release(x). |
| S_MovableRelease | 6 | objc_release(x), !clang.imprecise_release. |
