ABSTRACT:
A system that reduces overly optimistic program execution. During operation, the system encounters a bounded-execution block while executing a program, wherein the bounded execution block includes a primary path and a secondary path. Next, the system executes the bounded execution block. After executing the bounded execution block, the system determines whether executing instructions on the primary path is preferable to executing instructions on the secondary path based on information gathered while executing the bounded-execution block. If not, the system dynamically modifies the instructions of the bounded-execution block so that during subsequent passes through the bounded-execution block, the instructions on the secondary path are executed instead of the instructions on the primary path.
