摘要:
A computer-implemented method includes the following operations. A transactional lock elision transaction including a critical section is executed. The critical section is processed. After the processing of the critical section and prior to a commit point in the transactional lock elision transaction, a status of a lock is checked. Responsive to a determination that a status of the lock is free, a result of the transactional lock elision transaction is committed.
