2018-04-19Auto merge of #48553 - seanmonstar:atomic-debug, r=alexcrichtonbors-5/+3
atomic: remove 'Atomic*' from Debug output For the same reason that we don't show `Vec { data: [0, 1, 2, 3] }`, but just the array, the `AtomicUsize(1000)` is noisy, and seeing just `1000` is likely better.
2018-04-16Auto merge of #49963 - llogiq:stabilize-13226, r=kennytmbors-12/+11
stabilize fetch_nand This closes #13226 and makes `Atomic*.fetch_nand` stable.

2018-04-05Rollup merge of #48658 - llogiq:no-more-cas, r=kennytmkennytm-0/+185
Add a generic CAS loop to std::sync::Atomic* This adds two new methods to both `AtomicIsize` and `AtomicUsize` with optimized safe compare-and-set loops, so users will no longer need to write their own, except in *very* strange circumstances. `update_and_fetch` will apply the function and return its result, whereas `fetch_and_update` will apply the function and return the previous value. This solves #48384 with `x.update_and_fetch(|x| x.max(y))`. It also relates to #48655 (which I misuse as tracking issue for now).. *note* This *might* need a crater run because the functions could clash with third party extension traits.
2018-03-30Add a generic CAS loop to std::sync::Atomic*Andre Bogus-0/+185
This adds a new method to all numeric `Atomic*` types with a safe compare-and-set loop, so users will no longer need to write their own, except in *very* strange circumstances. This solves #48384 with `x.fetch_max(_)`/`x.fetch_min(_)`. It also relates to #48655 (which I misuse as tracking issue for now). *note* This *might* need a crater run because the functions could clash with third party extension traits.

2017-11-29Rollup merge of #46293 - ollie27:atomic_bool_from, r=BurntSushikennytm-0/+7
impl From<bool> for AtomicBool This seems like an obvious omission from #45610. ~~I've used the same feature name and version in the hope that this can be backported to beta so it's stabilized with the other impls. If it can't be I'll change it to `1.24.0`.~~

2017-04-13Rename compiler_barrier to compiler_fenceJon Gjengset-6/+6
This addresses concerns raised following the merge of #41092. Specifically: > The naming of these seems surprising: the multithreaded functions (and > both the single and multithreaded intrinsics themselves) are fences, > but this is a barrier. It's not incorrect, but the latter is both > inconsistent with the existing functions and slightly confusing with > another type in std (e.g., `Barrier`). `compiler_fence` carries the same semantic implication that this is a compiler-only operation, while being more in line with the fence/barrier concepts already in use in `std`.
2017-04-08Auto merge of #41092 - jonhoo:std-fence-intrinsics, r=alexcrichtonbors-0/+41
Add safe wrapper for atomic_compilerfence intrinsics This PR adds a proposed safe wrapper for the `atomic_singlethreadfence_*` intrinsics introduced by [RFC #888](https://github.com/rust-lang/rfcs/pull/888). See #41091 for further discussion.

* Since the switch to pulldown-cmark reference links need a blank line before the URLs. * Reference link references are not case sensitive. * Doc comments need to be indented uniformly otherwise rustdoc gets confused.
