This commit is an attempt to debug #38620 since we're unable to reproduce it
locally. It follows the [advice] of those with AppVeyor to use the `handle.exe`
tool to try to debug what processes have a handle to the file open.
This won't be guaranteed to actually help us, but hopefully it'll diagnose
something at some point?

On Android we only have one test thread for supposed problems with concurrency
and the remote debugger. Not all of our suites require one concurrency, however,
and suites like compile-fail or pretty can be much faster if they're
parallelized on Travis.
This commit only sets the test threads to one on Android for suites which
actually run code, and other suites aren't tampered with.

A tweak was made to dependencies in #38451 but the makefiles weren't updated to
accompany this. Instead of trying to integerate the `build_helper` crate into
the makefiles (which currently isn't present) this commit takes the approach of
just duplicating the required logic, which should be small enough for now.

adaptation to rustbuild for openbsd
Since the switch to rustbuild, the build for openbsd is broken:
- [X] `ar` inference based on compiler name is wrong (OpenBSD usually use `egcc`, but `ear` doesn't exist)
- [X] `make` isn't GNU-make under OpenBSD (and others BSD platforms)
- [x] `stdc++` isn't the right stdc++ library to link with (it should be `estdc++`)
- [x] corrects tests that don't pass anymore (problems related to rustbuild)

A more verbose matching failure for mir tests
This makes it easier to work with mir test failures during development.
- Show which expected line was not found
- Show full expected output
- Show full actual output
|
|
the diff extends build_helper to provide an function to return the
expected name of GNU-make on the host: "make" or "gmake".
Fixes #38429

This option lists all the tests and benchmarks a binary provides. By default the listing
is sent to stdout, but if --logfile is also specified, it is written there.
If filters are specified, they're applied before the output is emitted.

Filter matching is by substring by default. This makes it impossible
to run a single test if its name is a substring of some other test.
For example, its not possible to run just "mymod::test" with these
tests:
mymod::test
mymod::test1
mymod::test_module::moretests
You could declare by convention that no test has a name that's a
substring of another test, but that's not really practical.
This PR adds the "--exact" flag, to make filter matching exactly
match the complete name.

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.

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!

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.

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.

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...
Closes #36138

Take commandline arguments into account for incr. comp.
Implements the conservative strategy described in https://github.com/rust-lang/rust/issues/33727.
From now one, every time a new commandline option is added, one has to specify if it influences the incremental compilation cache. I've tried to implement this as automatic as possible: One just has to added either the `[TRACKED]` or the `[UNTRACKED]` marker next to the field. The `Options`, `CodegenOptions`, and `DebuggingOptions` definitions in `session::config` show plenty of examples.
The PR removes some cruft from `session::config::Options`, mostly unnecessary copies of flags also present in `DebuggingOptions` or `CodeGenOptions` in the same struct.
One notable removal is the `cfg` field that contained the values passed via `--cfg` commandline arguments. I chose to remove it because (1) its content is only a subset of what later is stored in `hir::Crate::config` and it's pretty likely that reading the cfgs from `Options` would not be what you wanted, and (2) we could not incorporate it into the dep-tracking hash of the `Options` struct because of how the test framework works, leaving us with a piece of untracked but vital data.
It is now recommended (just as before) to access the crate config via the `krate()` method in the HIR map.
Because the `cfg` field is not present in the `Options` struct any more, some methods in the `CompilerCalls` trait now take the crate config as an explicit parameter -- which might constitute a breaking change for plugin authors.
