Validates Call Frame Information across a stream of function frames.
Declared in <llvm/DWARFCFIChecker/DWARFCFIFunctionFrameAnalyzer.h>
class CFIFunctionFrameAnalyzer
: public CFIFunctionFrameReceiver
This class implements the CFIFunctionFrameReceiver interface to validate Call Frame Information in a stream of function frames. For validation, it instantiates a DWARFCFIAnalysis for each frame. The errors/warnings are emitted through the MCContext instance to the constructor. If a frame finishes without being started or if all the frames are not finished before this classes is destructed, the program fails through an assertion.
