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.
[LLVM 4.0] Update LLVM global variable debug info API for 4.0
This teaches Rust about an LLVM 4.0 API change for creating debug info
for global variables.
This change was made in upstream LLVM patch https://reviews.llvm.org/D20147
This is almost a 1:1 copy of how clang did it in http://reviews.llvm.org/D20415
- The discriminant must be first in all variants.
- The loop responsible for patching enum variants when the discriminant is enlarged was nonfunctional.
Document --test-args for rustbuild
There are three changes:
* Replace --filter with --test-args
* Delete `./x.py test src/test/run-pass/assert-*` example, which doesn't work
* As driveby, update Buildbot URLs to https
Fix#38275.

Fix travis builds
After reading some articles [1] [2] yesterday about Docker and the "init"
process I got to thinking about the problems that we've been seeing on Travis.
The basic problem is that a Linux system may need an "init" process to work
properly when processes become zombies. Docker by default doesn't handle this
and the root process typically isn't an init process, so this can occasionally
cause quite a few problems.
We've been seeing spurious errors on Travis inside containers which look like
OOM and such, but my guess is that zombie processes were being reparented to the
top-level shell. The shell didn't expect the zombies and then behaved very
strangely.
This commit fixes these problems by using Yelp's "dumb-init" program [2] as the
init process in all of our containers. This ensures that there's a valid init
ready to reap children when they're reparented, which our test suite apparently
generates a bunch of throughout the tests and such.

libtest: add --exact to make filter matching exact
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.
Another round of nightly fixes
Another three separate errors happened last night:
* Race condition in save analysis failed the OX build
* Packaging docs that don't exist failed the Android build
* Packaging save-analysis that doesn't exist failed the cross host builds
It just never ends...
This commit skips a few more dist tragets during compilation which shouldn't be
necessary.
* First, when packaging std we only take action when the host target is the
build target. Otherwise we package the same artifacts a number of times, which
shouldn't be necessary.
* Next, we apply the same logic to the save-analysis build. This is actually
required for correctness as the build compiler is the only one which actually
has save analysis information. This should fix an error seen on nightlies.
The OSX bots failed last night due a race condition in save analysis where
concurrent calls to `fs::create_dir_all` conflicted with one another. This
replaces the relevant function call with `fs::create_dir_racy` which is defined
internally to the compiler.
[LLVM 4.0] Move debuginfo alignment argument
Alignment was removed from createBasicType and moved to
- createGlobalVariable
- createAutoVariable
- createStaticMemberType (unused in Rust)
- createTempGlobalVariableFwdDecl (unused in Rust)

[MSP430] Do not generate '@' character in symbol names.
MSP430 assembler does not like '@' character in symbol names, so we need
to replace it with some other character.

feat(rustdoc): harmonise error messages
Based on unix tools wording, it follows a standard format: `program_name: context: error message`, potentially prompting the user to use the `--help` option.
This is clearly meant to trigger some discussion on #38084, as messages still use `stdout` and `stderr` somewhat arbitrarily, and there are a few `error!()` calls as well.
This option is intended to be used like:
./x.py build --stage 1 --keep-stage 0
Which skips all stage 0 steps, so that stage 1 can be recompiled
directly (even if for example libcore has changes).
This is useful when working on `cfg(not(stage0))` parts of the
libraries, or when re-running stage 1 tests in libraries in general.
