Public Member Functions
bool isFDE () const
Returns true if this frame is an FDE, false for a CIE.
bool isCIE () const
Returns true if this frame is a CIE, false for an FDE.
Edge * getPersonalityEdge () const
If this is a CIE record, returns the Edge pointing at the personality function, if any.
Edge * getCIEEdge () const
If this is an FDE record, returns the Edge pointing to the CIE.
Edge * getPCBeginEdge () const
If this is an FDE record, returns the Edge pointing at the PC-begin symbol.

◆ FromEdgeScan()

Identify CFI record type and edges based on number and order of edges in the given block only.

This assumes that the block contains one CFI record that has already been split out and fixed by the DWARFRecordSplitter and EHFrameEdgeFixer passes.

Zero or one outgoing edges: Record is CIE. If present, edge points to personality.

Two or three outgoing edges: Record is an FDE. First edge points to CIE, second to PC-begin, third (if present) to LSDA.

It is illegal to call this function on a block with four or more edges.

◆ getCIEEdge()

Edge * llvm::jitlink::EHFrameCFIBlockInspector::getCIEEdge ( ) const inline

If this is an FDE record, returns the Edge pointing to the CIE.

If this is a CIE record, returns null.

The result is not valid if any modification has been made to the block after parsing.

◆ getLSDAEdge()

Edge * llvm::jitlink::EHFrameCFIBlockInspector::getLSDAEdge ( ) const inline

◆ getPCBeginEdge()

Edge * llvm::jitlink::EHFrameCFIBlockInspector::getPCBeginEdge ( ) const inline

If this is an FDE record, returns the Edge pointing at the PC-begin symbol.

If this a CIE record, returns null.
