2014-04-10 | benchtests: Add pthread_once common-case test. | Torvald Riegel | 1 | -0/+9 | |
We have a single thread that runs a no-op initialization once and then repeatedly runs checks of the initialization (i.e., an acquire load and conditional jump) in a tight loop. This gives us, on average, the best-case latency of pthread_once (the initialization is the exactly-once slow path, and we're not looking at initialization-related synchronization overheads in this case). |
