2019-10-13Rollup merge of #65214 - Amanieu:cfg_atomic, r=alexcrichtonMazdak Farrokhzad-1/+1
Split non-CAS atomic support off into target_has_atomic_load_store This PR implements my proposed changes in https://github.com/rust-lang/rust/issues/32976#issuecomment-518542029 by removing `target_has_atomic = "cas"` and splitting `target_has_atomic` into two separate `cfg`s: * `target_has_atomic = 8/16/32/64/128`: This indicates the largest width that the target can atomically CAS (which implies support for all atomic operations). * ` target_has_atomic_load_store = 8/16/32/64/128`: This indicates the largest width that the target can support loading or storing atomically (but may not support CAS). cc #32976 r? @alexcrichton

2019-07-30Rollup merge of #63095 - Centril:incomplete-features-lint, r=varkorMazdak Farrokhzad-0/+1
Turn `INCOMPLETE_FEATURES` into lint We do this because it is annoying to see the warning when building rustc and because this is better from a "separation of concerns" POV. The drawback to this change is that this will respect `--cap-lints`. Also note that this is not a buffered lint so if there are fatal parser errors then the lint will not trigger. r? @varkor

2019-07-13Auto merge of #61953 - Centril:shared-from-iter, r=RalfJungbors-0/+1
Add `impl<T> FromIterator<T> for Arc/Rc<[T]>` Add implementations of `FromIterator<T> for Arc/Rc<[T]>` with symmetrical logic. This also takes advantage of specialization in the case of iterators with known length (`TrustedLen`) to elide the final allocation/copying from a `Vec<T>` into `Rc<[T]>` because we can allocate the space for the `Rc<[T]>` directly when the size is known. This is the primary motivation and why this is to be preferred over `iter.collect::<Vec<_>>().into(): Rc<[T]>`. Moreover, this PR does some refactoring in some places. r? @RalfJung for the code cc @alexcrichton from T-libs

Implement specialized nth_back() for Box and Windows. Hi there, this is my first pull request to rust :-) I started implementing some specializations for DoubleEndedIterator::nth_back() and these are the first two. The problem has been discussed in #54054 and nth_back() is tracked in #56995. I'm stuck with the next implementation so I though I do a PR for the ones I'm confident with to get some feedback.

2019-02-16Rollup merge of #58468 - RalfJung:maybe-uninit-split, r=Centrilkennytm-1/+1
split MaybeUninit into several features, expand docs a bit This splits the `maybe_uninit` feature gate into several: * `maybe_uninit` for what we will hopefully stabilize soon-ish. * `maybe_uninit_ref` for creating references into `MaybeUninit`, for which the rules are not yet clear. * `maybe_uninit_slice` for handling slices of `MaybeUninit`, which needs more API design work. * `maybe_uninit_array` for creating arrays of `MaybeUninit` using a macro (because we don't have https://github.com/rust-lang/rust/issues/49147 yet). Is that an okay thing to do? The goal is to help people avoid APIs we do not want to stabilize yet. I used this to make sure rustc itself does not use `get_ref` and `get_mut`. I also extended the docs to advise against uninitialized integers -- again this is something for which the rules are still being discussed.

2019-02-03Auto merge of #58081 - Centril:liballoc-2018, r=oli-obkbors-3/+4
Transition liballoc to Rust 2018 This transitions liballoc to Rust 2018 edition and applies relevant idiom lints. I also did a small bit of drive-by cleanup along the way. r? @oli-obk I started with liballoc since it seemed easiest. In particular, adding `edition = "2018"` to libcore gave me way too many errors due to stdsimd. Ideally we should be able to continue this crate-by-crate until all crates use 2018.
