2018-01-06Rollup merge of #47165 - mbrubeck:args, r=alexcrichtonGuillaume Gomez-23/+16
[unix] Don't clone command-line args on startup Fixes part of #47164 and simplifies the `args` code on non-Apple Unix platforms. Note: This could change behavior for programs that use both `std::env::args` *and* unsafe code that mutates `argv` directly. However, these programs already behave differently on different platforms. The new behavior on non-Apple platforms is closer to the existing behavior on Apple platforms.

2018-01-05Rollup merge of #47030 - ollie27:stab, r=alexcrichtonkennytm-14/+14
Correct a few stability attributes * The extra impls for `ManuallyDrop` were added in #44310 which was only stabilised in 1.22.0. * The impls for `SliceIndex` were stabilised in #43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable. * The `From` impls for atomic integers were added in #45610 but most atomic integers are still unstable. * The `shared_from_slice2` impls were added in #45990 but they won't be stable until 1.24.0. * The `Mutex` and `RwLock` impls were added in #46082 but won't be stable until 1.24.0.

2017-12-29Auto merge of #47026 - EdSchouten:cloudabi-unwind, r=kennytmbors-1/+8
Link against -lunwind on CloudABI. CloudABI makes use of LLVM's libunwind to do stack unwinding. It is installed under the name libunwind.a.

Don't attempt to build libunwind on CloudABI, as libunwind is already provided by the system by default.
2017-12-28Remove an unused import for cfg(not(feature = "backtrace")).Ed Schouten-2/+0
The 'mem' module is not used for this specific code. This was copy-pasted in by accident when adding RFC 1937 (? in main) support.

2017-12-27Auto merge of #46479 - bkchr:termination_trait, r=arielb1bors-2/+144
Implements RFC 1937: `?` in `main` This is the first part of the RFC 1937 that supports new `Termination` trait in the rust `main` function. Thanks @nikomatsakis, @arielb1 and all other people in the gitter channel for all your help! The support for doctest and `#[test]` is still missing, bu as @nikomatsakis said, smaller pull requests are better :)

kennytm:45861-step-4-5-6-7-upload-test-result-and-remove-toolstate-toml, r=alexcrichton [auto-toolstate] Upload the toolstate result to an external git repository, and removes BuildExpectation This PR consists of 3 commits. 1. (Steps 4–6) The `toolstate.json` output previously collected is now pushed to the https://github.com/rust-lang-nursery/rust-toolstate repository. 2. (Step 7) Revert commit ab018c7, thus removing all traces of `BuildExpectation` and `toolstate.toml`. 3. (Step 8) Adjust CONTRIBUTION.md for the new procedure. These are the last steps of #45861. After this PR, the toolstate will be automatically computed and published to https://rust-lang-nursery.github.io/rust-toolstate/. There is no need to manage toolstate.toml again. Closes #45861.
2017-12-27Revert "Add a file to trivially disable tool building or testing"kennytm-6/+3
This reverts commit ab018c76e14b87f3c9e0b7384cc9b02d94779cd5. This also adds the `ToolBuild::is_ext_tool` field to replace the previous `ToolBuild::expectation` field, to indicate whether a build-failure of certain tool is essential.

2017-12-22Rollup merge of #46898 - tspiteri:int-overflow-not-underflow, r=steveklabnikkennytm-2/+2
docs: do not call integer overflows as underflows In the API docs, integer overflow is sometimes called underflow. Underflow is really when the magnitude of a floating-point number is too small so the number underflows to subnormal or zero. With integers it is always overflow, even if the expected result is less than the minimum number that can be represented.
