Detailed Description

Handle function pointer.

Constructor & Destructor Documentation

BTFTypeFuncProto()

BTFTypeFuncProto::BTFTypeFuncProto	(	const DISubroutineType *	STy,
		uint32_t	VLen,
		const std::unordered_map< uint32_t, StringRef > &	FuncArgNames
	)

The Func kind represents both subprogram and pointee of function pointers.

If the FuncName is empty, it represents a pointee of function pointer. Otherwise, it represents a subprogram. The func arg names are empty for pointee of function pointer case, and are valid names for subprogram.
