Detailed Description

Calls other code.

Control flow is transfered to ptr, additional operands are passed to the called code. Called code usually performs a return operation. The operands of this return operation are the result of the Call node.


Enumeration Type Documentation

enum n_Call

Input numbers for Call node.

Function Documentation

int Call_has_callees ( const ir_node node)

Sets, get and remove the callee information for a Call node.

The callee information lists all method entities that can be called from this node. If the address expression can not be analyzed fully, e.g., as entities can be called that are not in the compilation unit, the array contains the unknown_entity. The array contains only entities with peculiarity_existent, but with all kinds of visibility. The entities not necessarily contain an irg.

The array is only accessible if callee information is valid. See flag in graph.

The memory allocated for the array is managed automatically, i.e., it must not be freed if the Call node is removed from the graph.

Parameters:
nodeA Call node.
ir_entity* get_Call_callee ( const ir_node node,
size_t  pos 
)

Returns callee number pos of Call node node.

ir_node* get_Call_mem ( const ir_node node)

size_t get_Call_n_callees ( const ir_node node)

Returns the number of callees of Call node node.

size_t get_Call_n_params ( const ir_node node)

Returns the number of parameters of a call.

ir_node* get_Call_param ( const ir_node node,
int  pos 
)

Returns type attribute of a Call node.

ir_op* get_op_Call ( void  )

Returns opcode for Call nodes.

int is_Call ( const ir_node node)
