Function Documentation

ir_node* get_Cast_op

(

const ir_node *

node

)

Returns op input of a Cast node.

ir_type* get_Cast_type

(

const ir_node *

node

)

Returns type attribute of a Cast node.

ir_op* get_op_Cast

(

void

)

Returns opcode for Cast nodes.

int is_Cast

(

const ir_node *

node

)

Test if node is a Cast.

Returns:

1 if the node is a Cast node, 0 otherwise

int is_Cast_downcast

(

ir_node *

node

)

Checks for downcast.

Returns true if the Cast node casts a class type to a sub type. Works also for pointers to classes (recursively).

Needs typeinfo calculated.

int is_Cast_upcast

(

ir_node *

node

)

Checks for upcast.

Returns true if the Cast node casts a class type to a super type. Works also for pointers to classes (recursively).

Needs typeinfo calculated.

ir_node* new_Cast	(	ir_node *	irn_op,
		ir_type *	type
	)

Construct a Cast node.

Parameters:

irn_op	operand
type	target type of the case

ir_node* new_d_Cast	(	dbg_info *	dbgi,
		ir_node *	irn_op,
		ir_type *	type
	)

Construct a Cast node.

Parameters:

dbgi	A pointer to debug information.
irn_op	operand
type	target type of the case

ir_node* new_r_Cast	(	ir_node *	block,
		ir_node *	irn_op,
		ir_type *	type
	)

Construct a Cast node.

Parameters:

block	The IR block the node belongs to.
irn_op	operand
type	target type of the case

ir_node* new_rd_Cast	(	dbg_info *	dbgi,
		ir_node *	block,
		ir_node *	irn_op,
		ir_type *	type
	)

Construct a Cast node.

Parameters:

dbgi	A pointer to debug information.
block	The IR block the node belongs to.
irn_op	operand
type	target type of the case

void set_Cast_op	(	ir_node *	node,
		ir_node *	op
	)

Sets op input of a Cast node.

void set_Cast_type	(	ir_node *	node,
		ir_type *	type
	)

Sets type attribute of a Cast node.
