Constructor & Destructor Documentation

◆ EPCEHFrameRegistrar()

llvm::orc::EPCEHFrameRegistrar::EPCEHFrameRegistrar	(	ExecutionSession &	ES,
		ExecutorAddr	RegisterEHFrameWrapperFnAddr,
		ExecutorAddr	DeregisterEHFRameWrapperFnAddr
	)

inline

Create a EPCEHFrameRegistrar with the given ExecutorProcessControl object and registration/deregistration function addresses.

Member Function Documentation

◆ Create()

Expected< std::unique_ptr< EPCEHFrameRegistrar > > llvm::orc::EPCEHFrameRegistrar::Create	(	ExecutionSession &	ES,
		std::optional< ExecutorAddr >	RegistrationFunctionsDylib = `std::nullopt`
	)

static

Create from a ExecutorProcessControl instance alone.

This will use the EPC's lookupSymbols method to find the registration/deregistration function addresses by name.

If RegistrationFunctionsDylib is non-None then it will be searched to find the registration functions. If it is None then the process dylib will be loaded to find the registration functions.
