virtual size_t	asBytes (void *buf, size_t max_size)
	Instruction classes can override this function to return a a representation of themselves as a blob of bytes, generally assumed to be that instructions ExtMachInst.

Public Member Functions inherited from gem5::RefCounted
	RefCounted ()
	We initialize the reference count to zero and the first object to take ownership of it must increment it to one.

virtual	~RefCounted ()
	We make the destructor virtual because we're likely to have virtual functions on reference counted objects.

void	incref () const
	Increment the reference count.

void	decref () const
	Decrement the reference count and destroy the object if all references are gone.
