Abstract
Methods and apparatus for reducing a control flow graph are disclosed. A disclosed method comprises: creating a points-to set associated with a function in a computer program; determining if a control flow edge between: (1) a call-site associated with a restore and return instruction and (2) a successor block following the call-site is removable from a control flow graph representing the computer program; and removing the control flow edge if it is determined that the control flow edge is removable.
