Functions
void	compute_cdep (ir_graph *irg)
	Computes the control dependence graph for a graph.
void	free_cdep (ir_graph *irg)
	Frees the control dependence info.
ir_node *	get_cdep_node (const ir_cdep *cdep)
	Returns control dependent block.
ir_cdep *	get_cdep_next (const ir_cdep *cdep)
	Returns next entry in a list of cdeps.
ir_cdep *	find_cdep (const ir_node *block)
