Detailed Description

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".

void free_irg_outs ( ir_graph * irg )

Frees memory occupied by out edges data structures.

ir_node* get_Block_cfg_out	(	const ir_node *	node,
		unsigned	pos
	)

Access predecessor n, ignore keep-alives.

ir_node* get_Block_cfg_out_ex	(	const ir_node *	node,
		unsigned	pos,
		int *	in_pos
	)

Access predecessor n, ignore keep-alives also return its input position.

ir_node* get_Block_cfg_out_ka	(	const ir_node *	node,
		unsigned	pos
	)

Access predecessor n, honor keep-alives.

unsigned get_Block_n_cfg_outs ( const ir_node * node )

Returns the number of control flow successors, ignore keep-alives.

unsigned get_Block_n_cfg_outs_ka ( const ir_node * node )

Returns the number of control flow successors, honor keep-alives.

unsigned 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,
		unsigned	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,
		unsigned	pos,
		int *	in_pos
	)

Returns the User and its input position from the Def-Use edge of def at position pos.

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".
