Typedef Documentation

typedef ir_node* uninitialized_local_variable_func_t(ir_graph *irg, ir_mode *mode, int pos)

This function is called, whenever a local variable is used before definition.

Parameters:

irg	the IR graph on which this happens
mode	the mode of the local var
pos	position chosen be the frontend for this variable (n_loc)

Returns:: a firm node of mode mode that initializes the var at position pos

Note:: Do not return NULL! If this function is not set, FIRM will create a const node with tarval BAD. Use set_irg_loc_description()/get_irg_loc_description() to assign additional informations to local variables.

void add_immBlock_pred	(	ir_node *	immblock,
		ir_node *	jmp
	)

Add a control flow edge to an immature block.

int find_value ( ir_node * value )

Find the value number for a node in the current block.

Parameters:

value the searched value

Returns:: the value number of the value or -1 if this value has no value number in the current block.

ir_node* get_cur_block ( void )

Returns the current block of the current graph.

ir_graph* get_current_ir_graph ( void )

Returns graph which is currently constructed.

ir_node* get_r_cur_block ( ir_graph * irg )

Returns current block of a given graph.

ir_node* get_r_store ( ir_graph * irg )

Returns current memory state for a given graph.

See also:: get_store()

ir_node* get_r_value	(	ir_graph *	irg,
		int	pos,
		ir_mode *	mode
	)

Returns the current value of a local variable in given graph.

See also:: get_value()

ir_node* get_store ( void )

Returns the current memory state.

Use this function to obtain the last definition of the memory state. This call automatically inserts Phi nodes for the memory state value.

ir_node* get_value	(	int	pos,
		ir_mode *	mode
	)

Returns the current value of a local variable.

Use this function to obtain the last definition of the local variable associated with pos. Pos may not exceed the value passed as n_loc to new_ir_graph. This call automatically inserts Phi nodes.

Parameters:

pos	The position/id of the local variable.
*mode	The mode of the value to get.

ir_mode* ir_guess_mode ( int pos )

Try to guess the mode of a local variable.

This is done by recursively going up the control flow graph until we find a definition for the variable. The mode of the first found definition is returned. NULL in case no definition is found.

Parameters:

pos	The position/id of the local variable.

ir_mode* ir_r_guess_mode	(	ir_graph *	irg,
		int	pos
	)

Try to guess the mode of a local variable in a given graph.

void ir_set_uninitialized_local_variable_func ( uninitialized_local_variable_func_t * func )

Register a new callback for the case that the value of an uninitialized variable is requested.

void irg_finalize_cons ( ir_graph * irg )

Puts the graph into state "phase_high".

void irp_finalize_cons ( void )

Puts the program and all graphs into state phase_high.

This also remarks, the construction of types is finished, e.g., that no more subtypes will be added.

void keep_alive ( ir_node * ka )

keep this node alive even if End is not control-reachable from it

Parameters:

ka	The node to keep alive.

void mature_immBlock ( ir_node * block )

Finalize a Block node, when all control flows are known.

ir_node* new_d_immBlock ( dbg_info * db )

Create an immature Block.

An immature Block has an unknown number of predecessors. Predecessors can be added with add_immBlock_pred(). Once all predecessors are added the block must be matured.

Adds the block to the graph in current_ir_graph. This constructor can only be used if the graph is in state_building.

ir_node* new_immBlock ( void )

Create an immature Block.

An immature Block has an unknown number of predecessors. Predecessors can be added with add_immBlock_pred(). Once all predecessors are added the block must be matured.

Adds the block to the graph in current_ir_graph. This constructor can only be used if the graph is in state_building.

ir_node* new_r_immBlock ( ir_graph * irg )

Create an immature Block.

An immature Block has an unknown number of predecessors. Predecessors can be added with add_immBlock_pred(). Once all predecessors are added the block must be matured.

This constructor can only be used if the graph is in state_building.

ir_node* new_rd_immBlock	(	dbg_info *	db,
		ir_graph *	irg
	)

Create an immature Block.

An immature Block has an unknown number of predecessors. Predecessors can be added with add_immBlock_pred(). Once all predecessors are added the block must be matured.

This constructor can only be used if the graph is in state_building.

int r_find_value	(	ir_graph *	irg,

Sets graph which is currently constructed.

void set_r_cur_block	(	ir_graph *	irg,
		ir_node *	target
	)

Sets current block of a given graph.

See also:: set_cur_block()

void set_r_store	(	ir_graph *	irg,
		ir_node *	store
	)

Sets current memory state for a given graph.

void set_r_value	(	ir_graph *	irg,
		int	pos,
		ir_node *	value
	)

Sets current value of a variable in a given graph.

void set_store ( ir_node * store )

Remark a new definition of the memory state.

Use this function to remember a new definition of the memory state. This call is needed to automatically inserts Phi nodes.

Parameters:

*store The new memory state.

void set_value	(	int	pos,
		ir_node *	value
