commit c358979d7f45fc7624abc2f14e6f36f25ac9acc0 Author: Hui <hui.xie1990@gmail.com> Date: Sun Jul 6 09:23:19 2025 +0100 [libc++] fix atomic::wait memory order (#146267) Fixes #109290 See the GH issue for the details. In conclusion, we have two issues in the `atomic<T>::wait` when `T` does not match our `contention_t`: - We don't have a total single order which can leads to missed notification based on the Herd7 simulation on relaxed architectural like PowerPC - We assumed the platform wait (`futex_wait`/`__ulock_wait`) has seq_cst barrier internally but there is no such guarantee |
