This is one of the few POSIX APIs that was missing. It lets you choose a monotonic clock for your condition variables. This might improve perf on some platforms. It might also grant more flexibility with NTP configs. I know Qt is one project that believes it needs this. To introduce this, I needed to change some the *NSYNC APIs, to support passing a clock param. There's also new benchmarks, demonstrating Cosmopolitan's supremacy over many libc implementations when it comes to mutex performance. Cygwin has an alarmingly bad pthread_mutex_t implementation. It is so bad that they would have been significantly better off if they'd used naive spinlocks. |

DESCRIPTION libomp - LLVM's Compiler Runtime for Multiprocessing ORIGIN https://github.com/llvm/llvm-project/ commit 70c3e30e01bd123e87824e36b6e38a39451ac28d date Mon Jan 29 09:54:34 2024 +0800 LOCAL CHANGES - Use Cosmo's gettid() function - Ran third_party/openmp/generate.sh - Removed usage of syscall() function - Only enable hidden helper on GNU/Systemd - Made __kmp_get_load_balance() portable at runtime - Made __kmp_affinity_get_offline_cpus() portable at runtime - Turned off quad floating point support (why does openmp have it?) - Remove bloat for checking if multiple OpenMP libraries are linked
