 /// 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.
 ///
-/// The optimizations performed include elimination of redundant, partially
-/// redundant, and inconsequential reference count operations, elimination of
-/// redundant weak pointer operations, pattern-matching and replacement of
-/// low-level operations into higher-level operations, and numerous minor
-/// simplifications.
-///
-/// This file also defines a simple ARC-aware AliasAnalysis.
+/// 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.
