Detailed Description

A cache for the CodeExtractor analysis.

The operation CodeExtractor::extractCodeRegion is guaranteed not to invalidate this object. This object should conservatively be considered invalid if any other mutating operations on the IR occur.

Constructing this object is O(n) in the size of the function.

◆ getAllocas()

ArrayRef< AllocaInst * > llvm::CodeExtractorAnalysisCache::getAllocas ( ) const

inline

Get the allocas in the function at the time the analysis was created.

Note that some of these allocas may no longer be present in the function, due to CodeExtractor::extractCodeRegion.
