Detailed Description

This file defines a simple ARC-aware AliasAnalysis using special knowledge of Objective C to enhance other optimization passes which rely on the Alias Analysis infrastructure.

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.
