Previous custom assembly implementations of semaphore were + difficult to reason about or ensure that they were safe. The new version + of semaphore supports machines with 64-bit or 32-bit atomic operations. + The new semaphore algorithm is used by sem_init, sem_open, sem_post, + sem_wait, sem_timedwait, sem_trywait, and sem_getvalue. * Port to Altera Nios II has been contributed by Mentor Graphics. |
