Detailed Description

This file defines common definitions/declarations used by the ObjC ARC Optimizer.

ARC stands for Automatic Reference Counting and is a system for managing reference counts for objects in Objective C.

WARNING: This file knows about certain library functions. It recognizes them by name, and hardwires knowledge of their semantics.

WARNING: This file knows about how certain Objective-C library functions are used. Naive LLVM IR transformations which would otherwise be behavior-preserving may break these assumptions.
