Before:
```
Testing ["rustc_interface"] stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```
After:
```
Testing {rustc_interface} stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```
Note there is a slight consistency between `build` and `test`: The
former doesn't print "compiler artifacts". It would be annoying to fix
and doesn't hurt anything, so I left it be.
```
; x t rustc_interface --stage 0 --dry-run
Testing {rustc_interface} stage0 (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
; x b rustc_interface --stage 0 --dry-run
Building {rustc_interface} stage0 compiler artifacts (aarch64-unknown-linux-gnu -> aarch64-unknown-linux-gnu)
```
Previously, clean only supported `--stage 0` for specific crates.
The new `crate_description` function generates a string that looks
like
```
: {rustc_query_impl}
```

LLVM_CONFIG_PATH is no longer supported as of LLVM 16, switch to
using the cmake module instead.
We separately return the llvm-config and cmake directory paths,
because llvm-config always refers to the host binary, while
the cmake directory is for the target triple.
Fix `x setup -h -v` should work

I have to convert profile to path and back in order to remove special-casing in bootstrap. I also check for `dry_run` so that `config.toml` and/ or `.git/hooks/pre-push` will not be created if `--dry-run` is specified.
Please help me see if this is ok, thanks alot!
Add prototype to generate `COPYRIGHT` from REUSE metadata
This PR adds a prototype to generate the `COPYRIGHT` file from the metadata gathered with REUSE. There are two new tools:
* `src/tools/collect-license-metadata` invokes REUSE, parses its output and stores a concise JSON representation of the metadata in `src/etc/license-metadata.json`.
* `src/tools/generate-copyright` parses the metadata generated above, (in the future will) gather crate dependencies metadata, and renders the `COPYRIGHT.md` file.
Note that since the contents of those files are currently incorrect, rather than outputting in the paths above, the files will be stored in `build/` and not committed. This will be changed once we're confident about the metadata.
Eventually, `src/etc/license-metadata.json` will be committed into the repository and verified to be up to date by CI (similar to our GitHub Actions configuration), to avoid having people install REUSE on their local machine in most cases.
You can see the (incorrect) generated files in https://gist.github.com/pietroalbini/3f3f22b6f9cc8533abf7494b6a50cf97.

copy doc output files by format
This pr provides copying doc outputs by checking output format without removing output directory on each trigger.

bootstrap: add support for running Miri on a file
This enables:
```
./x.py run src/tools/miri --stage 0 --args src/tools/miri/tests/pass/hello.rs
```
That can be super helpful for debugging.
Also avoid sharing the Miri sysroot dir with a system-wide (rustup-managed) installation of Miri.
Fixes https://github.com/rust-lang/rust/issues/76666
This allows open() to be called from other places in bootstrap (I need
this for Ferrocene), and it simplifies the callers by moving the
"was_invoked_explicitly" check into the function.
Distribute bootstrap in CI
This pre-compiles bootstrap from source and adds it to the existing `rust-dev` component. There are two main goals here:
1. Make it faster to build rust from source, both the first time and incrementally
2. Make it easier to add non-python entrypoints, since they can call out to bootstrap directly rather than having to figure out the right flags to pre-compile it. This second part is still in a bit of flux, see the tracking issue below for more information.
There are also several changes to make bootstrap able to run on a machine other than the one it was built (particularly around `config.src` and `config.out` detection). I (`@jyn514)` am slightly concerned these will regress unless tested - maybe we should add an automated test that runs bootstrap in a chroot or something? Unclear whether the effort is worth the test coverage.
Helps with https://github.com/rust-lang/rust/issues/94829.
Distribute json doc
# Overview
We add a new component, `rust-json-docs`, to distribute the JSON version of rustdoc's output for public compiler crates (i.e. `std`, `alloc`, `proc_macro`, `core` and `test`).
As discussed in #101383, we do not bundle this up as part of the existing `rust-docs` component since `rustdoc`'s JSON format is still unstable.
# Open questions / Doubts
I tried my best, but I never touched this codebase and I couldn't find much documentation on how `dist` works - I pattern-matched existing code, which might have led to some non-sensical choices in the eyes of people more familiar with the codebase. In particular, I am not sure if my choice of adding a new config flag is appropriate or if the decision to build/not build the JSON docs is more appropriately gated by one of the existing flags.
Any suggestion is more than welcome.
Closes#101383
This CL modifies the handing of env vars during the bootstrap process in
two ways:
1. Replaces '-' characters with '_' characters in target names to
increase compatibility with different shells
2. Passes Stage0 snapshot compiler related env vars to early invocations
of Cargo
- Add a new `bootstrap` component
Originally, we planned to combine this with the `rust-dev` component.
However, I realized that would force LLVM to be redownloaded whenever bootstrap is modified.
LLVM is a much larger download, so split this to get better caching.
- Build bootstrap for all tier 1 and 2 targets
This PR will fix some typos detected by [typos].
I only picked the ones I was sure were spelling errors to fix, mostly in
the comments.

session: stabilize split debuginfo on linux
Stabilize the `-Csplit-debuginfo` flag...
- ...on Linux for all values of the flag. Split DWARF has been implemented for a few months, hasn't had any bug reports and has had some promising benchmarking for incremental debug build performance.
- ..on other platforms for the default value. It doesn't make any sense that `-Csplit-debuginfo=packed` is unstable on Windows MSVC when that's the default behaviour, but keep the other values unstable.

This builds `src/tools/rust-analyzer/crates/proc-macro-srv-cli` and
ships it as part of Rustc's dist component. This allows rust-analyzer's
proc macro support to work on all rustc versions (stable, beta and
nightly) starting now.
Enable check-cfg in stage0
Now that the bootstrap cargo supports `rustc-check-cfg` we can now enable it with `-Zcheck-cfg=output` and use it in `rustc_llvm` to unblock `--check-cfg` support in stage0.
