Member Function Documentation

getCapturesBefore()

CaptureComponents SimpleCaptureAnalysis::getCapturesBefore ( const Value * Object, const Instruction * I, bool OrAt )

overridevirtual

Return how Object may be captured before instruction I, considering only provenance captures.

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

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

Implements llvm::CaptureAnalysis.
