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 :)

2017-12-27Auto merge of #46977 - est31:column_fix, r=dtolnaybors-6/+12
Make the output of the column! macro 1 based Fixes #46868. I didn't add any regression tests as the change already had to change tests inside the codebase. r? @dtolnay

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.

2017-12-15Rollup merge of #46710 - xfix:patch-5, r=alexcrichtonSteve Klabnik-3/+0
Remove Sync and Send implementation for RawTable The implementation was introduced when changing hash storage from Unique to *mut, but it was changed back to Unique.
2017-12-14Auto merge of #45002 - oli-obk:miri, r=eddybbors-2/+2
Validate miri against the HIR const evaluator r? @eddyb cc @alexcrichton @arielb1 @RalfJung The interesting parts are the last few functions in `librustc_const_eval/eval.rs` * We warn if miri produces an error while HIR const eval does not. * We warn if miri produces a value that does not match the value produced by HIR const eval * if miri succeeds and HIR const eval fails, nothing is emitted, but we still return the HIR error * if both error, nothing is emitted and the HIR const eval error is returned So there are no actual changes, except that miri is forced to produce the same values as the old const eval. * This does **not** touch the const evaluator in trans at all. That will come in a future PR. * This does **not** cause any code to compile that didn't compile before. That will also come in the future It would be great if someone could start a crater run if travis passes
