Detailed Description

Out-Edges are the reverse of the edges in a firm graph (also called def-use edges)

Function Documentation

void assure_irg_outs ( ir_graph * irg )

Recomputes out edges if necessary.

void compute_irg_outs ( ir_graph * irg )

Computes the out edges.

Sets a flag in irg to "outs_consistent". If the graph is changed this flag must be set to "outs_inconsistent". Computes out edges from block to floating nodes even if graph is in state "op_pin_state_floats". Optimizes Tuple nodes.

void compute_irp_outs ( void )

Recomputes out edges for each graph where it is 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.

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
	)

Access predecessor n, honor keep-alives.

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.

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.

int get_irn_outs_computed ( const ir_node * node )

Returns 1 if outs have been computed for a node, 0 otherwise.

this is useful to detect newly created nodes that have no outs set yet

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.

Has its own visited flag, so that it can be interleaved with the other walker. node must be either op_Block or mode_X.

void irg_out_walk	(	ir_node *	node,
		irg_walk_func *	pre,
		irg_walk_func *	post,
		void *	env
	)

Walks over the graph starting at node.

Walks also if graph is in state "outs_inconsistent". Assumes current_ir_graph is set properly.

void set_irn_out	(	ir_node *	def,
		int	pos,
		ir_node *	use,
		int	in_pos
	)

Sets the User at position pos.

Parameters:

def	the Def node
pos	the number of the Def-Use edge tat is modified
use	the Use node
in_pos	the number of the corresponding Use-Def edge in the use node in array
