suggest removing type ascription in bad parsing position
Not sure how to test this with the non-nightly suggestion. Didn't add a new UI test because it already manifests in an existing UI test.
Fixes#95014
Skip a test if symlink creation is not possible
If someone running tests on Windows does not have Developer Mode enabled then creating symlinks will fail which in turn would cause this test to fail. This can be a stumbling block for contributors.
BTreeMap::entry: Avoid allocating if no insertion
This PR allows the `VacantEntry` to borrow from an empty tree with no root, and to lazily allocate a new root node when the user calls `.insert(value)`.

Provide more useful documentation of conversion methods
I thought that the documentation for these methods needed to be a bit more explanatory for new users. For advanced users, the comments are relatively unnecessary. I think it would be useful to explain precisely what the method does. As a new user, when you see the `into` method, where the type is inferred, if you are new you don't even know what you convert to, because it is implicit. I believe this can help new users understand.
Give more details in `Display` for `hir::Target`
Made because I was making a code change and got a very confusing "should be applied to a method, not a method" error.
```

With this change the error is more actionable

remove_dir_all: use fallback implementation on Miri
Fixes https://github.com/rust-lang/miri/issues/1966
The new implementation requires `openat`, `unlinkat`, and `fdopendir`. These cannot easily be shimmed in Miri since libstd does not expose APIs corresponding to them. So for now it is probably easiest to just use the fallback code in Miri. Nobody should run Miri as root anyway...
Fix debuginfo tests with GDB 11.2
GDB 11.2 added support for DW_ATE_UTF, which caused some test
failures. This fixes these tests by changing the format that is used,
and adds a new test to verify that characters are emitted as something
that GDB can print in a char-like way.
Fixes#94458
solaris build environment should include libsendfile/liblgrp
As of version 0.2.120 of the libc crate, the solaris target now requires
some additional libraries to be present in the sysroot. Note that the
solaris target doesn't really build against files from Solaris, but
rather against some files from DilOS (a platform similar to both Solaris
and illumos). Pull in the extra libraries and their compilation links
from that apt repository.
This aims to assist with rust-lang/rust#94052.

Extend --check-cfg tests to all predicate inside all/any
Now that https://github.com/rust-lang/rust/pull/94295 is merged it's time to add more tests to check that all predicate inside `all` and `any` are always checked.

Re-enable parallel debuginfo tests
Debuginfo tests are serialized due to some older version of LLDB.
However, that comment was last touched in 2014, so presumably these
older versions are long since obsolete.
Partially fixes bug #72719.
Relax tests for Windows dos device names
Windows 11 no longer turn paths ending with dos device names into device paths.
E.g. `C:\path\to\COM1.txt` used to get turned into `\\.\COM1`. Whereas now this path is left as is.
Note though that if the given path is an exact (case-insensitive) match for the string `COM1` then it'll still be converted to `\\.\COM1`.
Add a `process_group` method to UNIX `CommandExt`
- Tracking issue: #93857
- RFC: https://github.com/rust-lang/rfcs/pull/3228
Add a `process_group` method to `std::os::unix::process::CommandExt` that
allows setting the process group id (i.e. calling `setpgid`) in the child, thus
enabling users to set process groups while leveraging the `posix_spawn` fast
path.
