Andy Wingo	dd3953ef1a	Factor trace deque out to shared-worklist.h ... Also increase alignment to account for cache line prefetcher.	2024-07-08 10:42:58 +02:00
Andy Wingo	3d2a12c684	Rework parallel tracing state machine ... Instead of sending a message to each worker, we pthread_cond_broadcast at the start. Instead of having N worker threads, we have N-1 threads and the main thread also does work. Instead of termination being detected by the worker threads, let the main thread detect it. Avoid parallelism if the mark stack is small enough, which can be the case for ephemeron chains. Let aux threads exit when they have no work instead of spinning: sharing will start them up again.	2023-10-23 11:26:33 +02:00
