This makes it dissimilar to how core is structured on disk, but
more predictable on its own.

Make the directory structure reflect the module structure. I've always
found the existing structure confusing.

Most of the Rust community agrees that the vec! macro is clearer when
called using square brackets [] instead of regular brackets (). Most of
these ocurrences are from before macros allowed using different types of
brackets.
There is one left unchanged in a pretty-print test, as the pretty
printer still wants it to have regular brackets.

Prohibit patterns in trait methods without bodies
They are not properly type checked
```rust
trait Tr {
fn f(&a: u8); // <- This compiles
}
```
, mostly rejected by the parser already and generally don't make much sense.
This PR is kind of a missing part of https://github.com/rust-lang/rust/pull/35015.
Given the [statistics from crater](https://github.com/rust-lang/rust/pull/37378#issuecomment-256154994), the effect of this PR is mostly equivalent to improving `unused_mut` lint.

Removes the `STATUSES` static which duplicates truth from the pattern
match in `collect_lang_features`.
Fixes existing duplicates by renaming:
- never_type{,_impls} on `impl`s on `!`
- concat_idents{,_macro} on `macro_rules! concat_idents`
Fixes #37013.

`git ls-files` now exits zero when called with a missing file; check
that the file is included in the output before reporting a checked-in
binary. Observed with git 2.10.1 and tripped by a symlink created by
tests:

Add AppVeyor configuration to the repo
We hope to move to AppVeyor in the near future off of Buildbot + EC2. This adds
an `appveyor.yml` configuration file which is ready to run builds on the auto
branch. This is also accompanied with a few minor fixes to the build system and
such to accomodate AppVeyor.
The intention is that we're not switching over to AppVeyor entirely just yet,
but rather we'll watch the builds for a week or so. If everything checks out
then we'll start gating on AppVeyor instead of Buildbot!

The main change is to stop using javascript to generate the URLs and use
rustdoc instead.
This also adds run buttons to the error index examples.

As the entry point for building the Rust compiler, a good user experience hinges
on this compiling quickly to get to the meat of the problem. To that end use
`#[cfg]`-specific dependencies to avoid building Windows crates on Unix and drop
the `regex` crate for now which was easily replacable with some string
searching.

Leverage Cargo workspaces in rustbuild
This is a continuation of https://github.com/rust-lang/rust/pull/36032 which implements the change to use `cargo metadata` to learn about the crate graph.
|
|
This involves hacking the code used to run cargo test on various
packages, because it reads Cargo.lock to determine which packages should
be tested. This change implements a blacklist, since that will catch new
crates when they are added in the future.

std: Minor cleanup to libtest
* Don't spawn two threads for all tests, just one now that `catch_unwind` is
stable.
* Remove usage of the unstable `box` keyword
* Remove usage of the unstable `FnBox` trait
|
|
This commit blanket renames the `rustc_macro` infrastructure to `proc_macro`,
which reflects the general consensus of #35900. A follow up PR to Cargo will be
required to purge the `rustc-macro` name as well.

This is intended to maintain existing standards of code organization
in hopes that the standard library will continue to be refactored to
isolate platform-specific bits, making porting easier; where "standard
library" roughly means "all the dependencies of the std and test
crates".
This generally means placing restrictions on where `cfg(unix)`,
`cfg(windows)`, `cfg(target_os)` and `cfg(target_env)` may appear,
the basic objective being to isolate platform-specific code to the
platform-specific `std::sys` modules, and to the allocation,
unwinding, and libc crates.
Following are the basic rules, though there are currently
exceptions:
- core may not have platform-specific code
- liballoc_system may have platform-specific code
- liballoc_jemalloc may have platform-specific code
- libpanic_abort may have platform-specific code
- libpanic_unwind may have platform-specific code
- other crates in the std facade may not
- std may have platform-specific code in the following places
- sys/unix/
- sys/windows/
- os/
There are plenty of exceptions today though, noted in the whitelist.

libtest: add a --skip flag to the test runner
This flag takes a FILTER argument and instructs the test runner to skip
the tests whose names contain the word FILTER. --skip can be used
several times.
---
My motivation for submitting this is that while using [smoke] to run `std` unit tests for cross
targets I found that a few of the tests always fail due to limitations in QEMU (it can't handle too
many threads) and I'd like to skip these problematic tests from the command line to be able to run
the rest of the unit tests.
[smoke]: https://github.com/japaric/smoke
I know there is another mechanism to skip tests: `#[ignore]` but this doesn't work in my use case
because I can't (easily) modify the source of the standard libraries to `#[ignore]` some tests. And
even if I could, the change would involve conditionally ignoring some tests for some targets but
that's not a perfect solution because those tests should pass if executed on real hardware so they
should not be `#[ignored]` in that scenario.

* Hand rebased from Niels original work on 1.9.0
|
|
While it's possible that other linux systems will include "Microsoft" in
their /proc/version, this is deemed unlikely, and since this is a tidy
check, will likely be caught by buildbot/travis either way.

Fix ICE test in compiletest fail-tests
While working on Clippy which uses *compiletest*, I noticed that as long as all expected error are found, *compile-fail* tests will be marked *ok* even if there is an ICE. One function seems to have not been updated with JSON errors because ICEs are now reported like this:
```json
{"message":"../src/librustc/ty/context.rs:161: Attempted to intern `_` which contains inference types/regions in the global type context","code":null,"level":"error: internal compiler error","spans":[],"children":[],"rendered":null}
```
I don't think I can add a test for that.
I guess:

This adds support for building the Rust compiler and standard
library for s390x-linux, allowing a full cross-bootstrap sequence
to complete. This includes:
- Makefile/configure changes to allow native s390x builds
- Full Rust compiler support for the s390x C ABI
(only the non-vector ABI is supported at this point)
- Port of the standard library to s390x
- Update the liblibc submodule to a version including s390x support
- Testsuite fixes to allow clean "make check" on s390x
Caveats:
- Resets base cpu to "z10" to bring support in sync with the default
behaviour of other compilers on the platforms. (Usually, upstream
supports all older processors; a distribution build may then chose
to require a more recent base version.) (Also, using zEC12 causes
failures in the valgrind tests since valgrind doesn't fully support
this CPU yet.)
- z13 vector ABI is not yet supported. To ensure compatible code
generation, the -vector feature is passed to LLVM. Note that this
means that even when compiling for z13, no vector instructions
will be used. In the future, support for the vector ABI should be
added (this will require common code support for different ABIs
that need different data_layout strings on the same platform).
- Two test cases are (temporarily) ignored on s390x to allow passing
the test suite. The underlying issues still need to be fixed:
* debuginfo/simd.rs fails because of incorrect debug information.
This seems to be a LLVM bug (also seen with C code).
* run-pass/union/union-basic.rs simply seems to be incorrect for
all big-endian platforms.

We've got tests which require a particular version of LLVM to run as they're
testing bug fixes. Our build system, however, supports multiple LLVM versions,
so we can't run these tests on all LLVM versions.
This adds a new `min-llvm-version` directive for tests so they can opt out of
being run on older versions of LLVM. This then namely applies that logic to the
`issue-36023.rs` test case and...

Implement synchronization scheme for incr. comp. directory
This PR implements a copy-on-write-based synchronization scheme for the incremental compilation cache directory. For technical details, see the documentation at the beginning of `rustc_incremental/persist/fs.rs`.
The PR contains unit tests for some functions but for testing whether the scheme properly handles races, a more elaborate test setup would be needed. It would probably involve a small tool that allows to manipulate the incremental compilation directory in a controlled way and then letting a compiler instance run against directories in different states. I don't know if it's worth the trouble of adding another test category to `compiletest`, but I'd be happy to do so.
Fixes #32754
Fixes #34957
