2019-12-22Remove most files from format ignore listMark Rousskov-20/+23
Also moves formatting to use edition 2018, and to be done in parallel. This brings near-linear speed ups (at least with a small amount of cores).
2019-12-22Rollup merge of #67525 - Mark-Simulacrum:fix-toolstate-master, r=CentrilMazdak Farrokhzad-2/+5
Utilize rust-lang/rust commit hashes in toolstate When moving the script out of CI configuration and into a proper script we lost track of the current directory changing (and as such the parameters of the script needing to be different now).
2019-12-22Rollup merge of #67519 - Mark-Simulacrum:any-unsafe, r=CentrilMazdak Farrokhzad-0/+10
Document why Any is not an unsafe trait The added documentation is not public (i.e., not in a doc comment) but that seems appropriate for this sort of low-level detail. Fixes #62303
2019-12-22Rollup merge of #67508 - davesque:master, r=Dylan-DPCMazdak Farrokhzad-2/+2
Fix typo in path parser name It appears that a little typo crept into the name of a path parsing method.

Remove iter_private.rs The contents of this file have been moved in #56932 (520e8b0) and the file should have been removed as well.

2019-12-22Rollup merge of #67487 - GuillaumeGomez:rustdoc-mutability-removal, r=CentrilMazdak Farrokhzad-40/+23
Rustdoc mutability removal Fixes #67470. As discussed in another PR, the `clean::Mutability` type in rustdoc is useless. So let's remove it! r? @Centril

2019-12-22Rollup merge of #66877 - skinny121:const-eval-entry-points, r=oli-obkMazdak Farrokhzad-253/+195
Add simpler entry points to const eval for common usages. I found the `tcx.const_eval` API to be complex/awkward to work with, because of the inherent complexity from all of the different situations it is called from. Though it mainly used in one of the following ways: - Evaluates the value of a constant without any substitutions, e.g. evaluating a static, discriminant, etc. - Evaluates the value of a resolved instance of a constant. this happens when evaluating unevaluated constants or normalising trait constants. - Evaluates a promoted constant. This PR adds three new functions `const_eval_mono`, `const_eval_resolve`, and `const_eval_promoted` to `TyCtxt`, which each cater to one of the three ways `tcx.const_eval` is normally used.

2019-12-22Auto merge of #65939 - anp:incremental-rustfmt-rollout, r=Mark-Simulacrumbors-30/+181
Enable incremental rustfmt adoption Enables an incremental rollout of rustfmt usage within the compiler via a granular ignore configuration and automated enforcement. The decision to format the repository was approved in https://github.com/rust-lang/compiler-team/issues/80#issuecomment-491324079. This PR includes: * an `[ignore]` section to `rustfmt.toml` including most of the repository * `./x.py` downloads rustfmt from a specific nightly (we do not pin to beta or stable as we need unstable features) * an `./x.py fmt [--check]` command which runs cargo-fmt * `./x.py fmt --check` runs during the same test step as `src/tools/tidy`, on master, but not on beta or stable as we don't want to depend on nightly rustfmt there. * a commit to format `src/librustc_fs_util` as an initial target and to ensure enforcement is working from the start

2019-12-22Do not run if rustfmt.toml does not existMark Rousskov-2/+7
distcheck (and generally publishing tarballs) will not package rustfmt.toml and we for now still support running tidy etc in those tarballs.

2019-12-22Auto merge of #66931 - cjgillot:hirene-preamble, r=eddybbors-781/+856
Allocate HIR on an arena 1/4 This PR is the first in a series of 4, aiming at allocating the HIR on an arena, as a memory optimisation. 1. This first PR lays the groundwork and migrates some low-hanging fruits. 2. The second PR will migrate `hir::Expr`, `hir::Pat` and related. 3. The third PR will migrate `hir::Ty` and related. 4. The final PR will be dedicated to eventual cleanups. In order to make the transition as gradual as possible, some lowering routines receive `Box`-allocated data and move it into the arena. This is a bit wasteful, but hopefully temporary. Nonetheless, special care should be taken to avoid double arena allocations. Work mentored by @Zoxc.

2019-12-22Rollup merge of #67480 - rossmacarthur:fix-41260-avoid-issue-0-part-2, r=CentrilMazdak Farrokhzad-385/+384
Require issue = "none" over issue = "0" in unstable attributes These changes make the use of `issue = "none"` required in unstable attributes throughout the compiler. Notes: - #66299 is now in beta so `issue = "none"` is accepted. - The `tidy` tool now fails on `issue = "0"`. - Tests that used `issue = "0"` were changed to use `issue = "none"`, except for _one_ that asserts `issue = "0"` can still be used. - The compiler still allows `issue = "0"` because some submodules require it, this could be disallowed once these are updated. Resolves #41260 r? @varkor

Cleanup `lower_pattern_unadjusted` & Improve slice pat typeck Following up on https://github.com/rust-lang/rust/pull/67318, in this PR, the HAIR lowering of patterns (`lower_pattern_unadjusted`) is cleaned up with a focus on slice patterns (in particular, some dead code is removed). Moreover, `check_pat_slice` is refactored some more. r? @matthewjasper

2019-12-21Implement rustfmt running manually using ignore crateMark Rousskov-16/+48
This replaces cargo-fmt with rustfmt with --skip-children which should allow us to format code without running into rust-lang/rustfmt#3930. This also bumps up the version of rustfmt used to a more recent one.

2019-12-22Auto merge of #66932 - rust-lang:pass-check-runfail, r=petrochenkovbors-406/+613
Revamp `// run-fail` wrt. `--pass` & support `// build-fail` & `// check-fail` Revamp how `// run-fail` tests work internally by having a separate `FailMode` that does not interfere with `PassMode`. In particular, `--pass check` will now have no effect on `// *-fail` tests. Moreover, new test annotations `// check-fail` (the default) and `// build-fail` are added. The latter is useful to distinguish post-monomorphization failures from pre-monomorphization failures as seen throughout the PR. Finally, ensure that non-`Ui` tests do not listen to `--pass check` such that the flag can be used with e.g. `./x.py test --pass check` directly. Fixes #66929. Fixes #67128. r? @petrochenkov cc @RalfJung @ninjasource
