|INITIALIZE_PASS (ObjCARCAPElim,"objc-arc-apelim","ObjC ARC autorelease pool elimination", false, false) Pass *llvm|
This file defines ObjC ARC optimizations. ARC stands for Automatic Reference Counting and is a system for managing reference counts for objects in Objective C.
This specific file implements optimizations which remove extraneous autorelease pools.
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.
