… intrinsics. The default versions (atomic_load and atomic_store) are sequentially consistent. The atomic_load_acq intrinsic acquires as described in [1]. The atomic_store_rel intrinsic releases as described in [1]. [1]: http://llvm.org/docs/Atomics.html

It never is, it seems I neglected to remove that after copying the original definition of Load. It has been removed now. |

This pull request adds 4 atomic intrinsics to the compiler, in preparation for #5042. * `atomic_load(src: &int) -> int` performs an atomic sequentially consistent load. * `atomic_load_acq(src: &int) -> int` performs an atomic acquiring load. * `atomic_store(dst: &mut int, val: int)` performs an atomic sequentially consistent store. * `atomic_store_rel(dst: &mut int, val: int)` performs an atomic releasing store.
