pub unsafe extern "rust-intrinsic" fn atomic_or_acquire<T: Copy>(
    dst: *mut T,
    src: T,
) -> T

🔬This is a nightly-only experimental API. (core_intrinsics)

Bitwise or with the current value, returning the previous value.

The stabilized version of this intrinsic is available on the atomic types via the fetch_or method by passing Ordering::Acquire as the order. For example, AtomicBool::fetch_or.
