Detailed Description

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 an Unknown node. Use set_irg_loc_description()/get_irg_loc_description() to assign additional informations to local variables.

Function Documentation

void add_immBlock_pred	(	ir_node *	immblock,
		ir_node *	jmp
	)

Add a control flow edge to an immature 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 must be less than 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.

void set_cur_block ( ir_node * target )

Sets the current block in which the following constructors place the nodes they construct.

Parameters

target The new current block.

void set_current_ir_graph ( ir_graph * graph )

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.

See Also: set_store()

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 )

Memorize 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
	)

Memorize a new definition of a variable.

Use this function to remember a new definition of the value associated with pos. pos must be less than the value passed as n_loc to new_ir_graph. This call is needed to automatically inserts Phi nodes.

Parameters

pos	The position/id of the local variable.
*value	The new value written to the local variable.
