Abstract
A computer implemented control method, article of manufacture, and computer implemented system for determining whether stack allocation is possible. The method includes: allocating an object created by a method frame to a stack. The allocation is performed in response to: calling a first and second instruction in the method frame; the first instruction causes an escape of the object, and the second instruction cancels the escape of the object; the object does not escape to a thread other than a thread to which the object has escaped, at the point in time when the escape is cancelled; the first instruction has been called before the second instruction is called; and the object does not escape in accordance with an instruction other than the first instruction in the method frame, regardless of whether the object escapes in accordance with the first instruction.
