2017-05-18core: fix unused_macro warningJorge Aparicio-0/+1
when compiling the crate for a target with max-atomic-width = 0 fixes #42097
2017-05-02Rollup merge of #41217 - topecongiro:docs/atomic-fence, r=steveklabnikCorey Farwell-3/+52
Update docs of 'fence' This PR updates the docs for `std::sync::atomic::fence` with an example and a diagram. Part of #29377. r? @steveklabnik

2017-05-01Add an example for 'fence'topecongiro-3/+52
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.
