ir_tarval* get_Const_tarval ( const ir_node * node )

Returns tarval attribute of a Const node.

Definition at line 3110 of file gen_irnode.c.

ir_op* get_op_Const ( void )

Returns opcode for Const nodes.

Definition at line 889 of file gen_irnode.c.

References op_Const.

int is_Const ( const ir_node * node )

Test if node is a Const.

Returns: 1 if the node is a Const node, 0 otherwise

Definition at line 3105 of file gen_irnode.c.

int is_Const_all_one ( const ir_node * node )

Returns non-zero if the given Const node represents the constant with all bits set.

int is_Const_null ( const ir_node * node )

Returns non-zero if the given Const node represents the 0 constant.

int is_Const_one ( const ir_node * node )

Returns non-zero if the given Const node represents the 1 constant.

ir_node* new_Const ( ir_tarval * tarval )

Construct a Const node.

Parameters

tarval constant value (a tarval object)

Definition at line 884 of file gen_irnode.c.

References new_d_Const().

ir_node* new_Const_long	(	ir_mode *	mode,
		long	value
	)

Make a const from a long.

This is just convenience for the usual new_Const(mode, tarval_from_long(mode, ...)) pain.

Parameters

mode	The mode for the const.
value	The value of the constant.

Returns: A new const node.

ir_node* new_d_Const	(	dbg_info *	dbgi,
		ir_tarval *	tarval
	)

Construct a Const node.

Parameters

dbgi	A pointer to debug information.
tarval	constant value (a tarval object)

ir_node* new_d_Const_long	(	dbg_info *	db,
		ir_mode *	mode,
		long	value
	)

See Also: new_rd_Const_long()

Parameters

db	A pointer for debug information.
mode	The mode of the operands and results.
value	A value from which the tarval is made.

ir_node* new_r_Const	(	ir_graph *	irg,
		ir_tarval *	tarval
	)

Construct a Const node.

Parameters

irg	The IR graph the node belongs to.
tarval	constant value (a tarval object)

References new_rd_Const().

ir_node* new_r_Const_long	(	ir_graph *	irg,
		ir_mode *	mode,
		long	value
	)

Constructor for a Const node.

Adds the node to the start block.

The constant represents a target value.

Parameters

irg	The IR graph the node belongs to.
mode	The mode of the operands and the results.
value	A value from which the tarval is made.

ir_node* new_rd_Const	(	dbg_info *	dbgi,
		ir_graph *	irg,
		ir_tarval *	tarval
	)

Construct a Const node.

Parameters

dbgi	A pointer to debug information.
irg	The IR graph the node belongs to.
tarval	constant value (a tarval object)

		ir_graph *	irg,
		ir_mode *	mode,
		long	value
	)

Constructor for a Const node.

Adds the node to the start block.

The constant represents a target value.

Parameters

db	A pointer for debug information.
irg	The IR graph the node belongs to.
mode	The mode of the operands and results.
value	A value from which the tarval is made.

void set_Const_tarval	(	ir_node *	node,
		ir_tarval *	tarval
	)

Sets tarval attribute of a Const node.
