isNotCapturedBefore()

virtual bool llvm::CaptureAnalysis::isNotCapturedBefore ( const Value *  Object, const Instruction *  I, bool  OrAt  )

pure virtual

Check whether Object is not captured before instruction I.

If OrAt is true, captures by instruction I itself are also considered.

If I is nullptr, then captures at any point will be considered.

Implemented in llvm::SimpleCaptureAnalysis, and llvm::EarliestEscapeAnalysis.
