unsigned	getLayoutOrder () const
void	setLayoutOrder (unsigned Value)
virtual bool	hasInstructions () const
	Does this fragment have instructions emitted into it? By default this is false, but specific fragment types may set it to true.
virtual bool	alignToBundleEnd () const
	Should this fragment be placed at the end of an aligned bundle?
virtual void	setAlignToBundleEnd (bool V)
virtual uint8_t	getBundlePadding () const
	Get the padding size that must be inserted before this fragment. Used for bundling. By default, no padding is inserted. Note that padding size is restricted to 8 bits. This is an optimization to reduce the amount of space used for each fragment. In practice, larger padding should never be required.
virtual void	setBundlePadding (uint8_t N)
	Set the padding size for this fragment. By default it's a no-op, and only some fragments have a meaningful implementation.
void	dump ()
