For types that track whether or not there extant waiters (e.g. semaphore) internally, the __atomic_notify_address_bare() call was introduced to avoid the overhead of loading the atomic count of waiters. For platforms that don't have Futex, however, there was still a check for waiters, and seeing that there are none (because in the bare case, the count is not incremented), the notification is dropped. This commit addresses that case. libstdc++-v3/ChangeLog: * include/bits/atomic_wait.h: Always notify waiters in the case of 'bare' address notification. |
