uint64是一种无符号64位整数类型,atomic_fetch_add是一种原子操作函数,用于对指定的内存位置进行原子加法操作。然而,有时候在使用atomic_fetch_add函数时可能会遇到一些奇怪的行为。 这种奇怪行为可能是由于多线程并发访问同一个内存位置导致的。在多线程环境下,如果多个线程同时调用atomic_fetch_add函数对同一个内存位...
I suggest CAS2 is implemented in the atomic package similar to atomic.align64, operational for hardware that supports it. possibly also: atomic OR LL/SC Load-link/store-conditional — With the 2022 memory model, go1.19 atomics became usef...
Currently this test is completely xfailed as part of the patch #106077. But this test works on A and R profile, not in v7M profile. Because the test contain cases in which m-profile will fail for ...
本文简要介绍rust语言中 std::sync::atomic::AtomicU64.fetch_add 的用法。用法pub fn fetch_add(&self, val: u64, order: Ordering) -> u64 添加到当前值,返回前一个值。 此操作在溢出时回绕。 fetch_add 采用 Ordering 参数,该参数说明了此操作的内存顺序。所有排序模式都是可能的。请注意,使用 ...
