2019-12-23Auto merge of #67540 - Mark-Simulacrum:fmt-the-world, r=Centrilbors-74556/+66164
Format the world This PR modifies the formatting infrastructure a bit in the first commit (to enable the forgotten 2018 edition), as well as removes most directories from the ignore list in rustfmt.toml. It then follows that up with the second commit which runs `x.py fmt` and formats the entire repository. We continue to not format the test directory (`src/test`) because of interactions with pretty printing and, in part, because re-blessing all of those files is somewhat harder to review, so is best suited for a follow up PR in my opinion.
2019-12-22Change bound order in rustfmt testMark Rousskov-2/+2
It is unclear why this changed, but since it seems like a harmless change, we're going to move forward with reformatting.

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

Fix typo in path parser name It appears that a little typo crept into the name of a path parsing method.

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-32/+267
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

2019-12-22Auto 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.

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.
