Abstract
One embodiment of the present invention provides a system that merges checkpoints on a processor. The system starts by executing instructions speculatively during a speculative-execution episode. The system then generates a first checkpoint and a second checkpoint during the speculative-execution episode. Next, the system merges the first checkpoint with the second checkpoint during the speculative-execution episode, wherein merging the first and second checkpoints conserves processor resources.
