Functions
int	get_irn_n_outs (const ir_node *node)
	Returns the number of successors of the node:
ir_node *	get_irn_out (const ir_node *def, int pos)
	Returns the User of a node from the Def-Use edge at position pos.
ir_node *	get_irn_out_ex (const ir_node def, int pos, int in_pos)
	Returns the User and its input position from the Def-Use edge of def at position pos.
void	set_irn_out (ir_node def, int pos, ir_node use, int in_pos)
	Sets the User at position pos.
int	get_Block_n_cfg_outs (const ir_node *node)
	Returns the number of control flow successors, ignore keep-alives.
int	get_Block_n_cfg_outs_ka (const ir_node *node)
	Returns the number of control flow successors, honor keep-alives.
ir_node *	get_Block_cfg_out (const ir_node *node, int pos)
	Access predecessor n, ignore keep-alives.
ir_node *	get_Block_cfg_out_ka (const ir_node *node, int pos)

void	irg_out_walk (ir_node node, irg_walk_func pre, irg_walk_func post, void env)
	Walks over the graph starting at node.
void	irg_out_block_walk (ir_node node, irg_walk_func pre, irg_walk_func post, void env)
	Walks only over Block nodes in the graph.
int	get_irn_outs_computed (const ir_node *node)
	Returns 1 if outs have been computed for a node, 0 otherwise.
void	compute_irg_outs (ir_graph *irg)
	Computes the out edges.
void	compute_irp_outs (void)
	Recomputes out edges for each graph where it is necessary.
void	assure_irg_outs (ir_graph *irg)
	Recomputes out edges if necessary.
void	free_irg_outs (ir_graph *irg)
	Frees memory occupied by out edges datastructures.
void	free_irp_outs (void)
	Frees memory occupied by out edges datastructures in the whole program.
