warn newer available version of the x tool
This PR adds a check to `tidy` to assert that the installed version of `x` is equal to the version in `src/tools/x/Cargo.toml`. It adds a `--wrapper-version` argument to `x` to determine the version at runtime, .
It does not warn if `x` has not yet been installed, on the assumption that the user isn't interested in using it.

Only include metadata for non-dynamic libraries in rustc-dev
The actual object code should be linked from librustc_driver.so, which is still included in rustc-dev. This saves on download time and disk usage.
Fixes https://github.com/rust-lang/rust/issues/103538
|
|
This allows regenerating `src/stage0.json` on changes to the tool,
without needing to hard-code the date in the source.

Fix panic on `x build --help`
Fixes https://github.com/rust-lang/rust/issues/106313. This avoids trying to run `get_help` unless we actually need to see the paths that are available for the subcommand.
This originally regressed in https://github.com/rust-lang/rust/pull/106166.

Dont use `--merge-base` during bootstrap formatting subcommand
I use a development image with Ubuntu 20.04 LTS, which has git 2.25.
Recently, `./x.py test tidy --bless` regressed in #105702 because it uses the `--merge-base` option on `diff-index`, which was only introduced in git 2.30 (git/git@0f5a1d449b9538c2765de9d6683abbb83a7fb4e2). Luckily, it can be replicated via two calls to `git merge-base` + `git diff-index`, so let's just use that.

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)

Respect --set=target.platform when building rustbuild itself
`--set=target.platform.cc` and `--set=target.platform.cxx` are ignored if target is quoted.
`--set=target.platform.linker` is ignored if RUSTFLAGS is not set.

Previously, clean only supported `--stage 0` for specific crates.
The new `crate_description` function generates a string that looks
like
```
: {rustc_query_impl}
```

Avoid quoting targets that do not contain a period.

Allow cleaning individual crates
As a bonus, this stops special casing `clean` in `Builder`.
## Motivation
Cleaning artifacts isn't strictly necessary to get cargo to rebuild; `touch compiler/rustc_driver/src/lib.rs` (for example) will also work. There's two reasons I thought making this part of bootstrap proper was a better approach:
1. `touch` does not *remove* artifacts, it just causes a rebuild. This is unhelpful for when you want to measure how long the compiler itself takes to build (e.g. for https://github.com/rust-lang/rust/issues/65031).
2. It seems a little more discoverable; and I want to extend it in the future to things like `x clean --stage 1 rustc`, which makes it easier to work around https://github.com/rust-lang/rust/issues/76720 without having to completely wipe all the stage 0 artifacts, or having to be intimately familiar with which directories to remove.
|
|

This also makes the panic message a little more informative in case it
happens again.

Improve top-level docs
See a detailed explanation in the commit messages. This is a companion PR to https://github.com/rust-lang/rustc-dev-guide/pull/1528.
* Link to other resources instead of inlining their information
* Remove ancient and outdated reference to `config.mk`
* Suggest `profile = "user"` in the README
* Add detail about dependencies from the dev-guide
* Link to CONTRIBUTING.md instead of rustc-dev-guide in the main readme
* Link to `std-dev-guide` in CONTRIBUTING.md

Avoid running the `Profile` step twice on `x setup`
Prevents runs like the following:
```
$ x setup
Welcome to the Rust project! What do you want to do with x.py?
a) library: Contribute to the standard library
b) compiler: Contribute to the compiler itself
c) codegen: Contribute to the compiler, and also modify LLVM or codegen
d) tools: Contribute to tools which depend on the compiler, but do not modify it directly (e.g. rustdoc, clippy, miri)
e) user: Install Rust from source
Please choose one (a/b/c/d/e): b
To get started, try one of the following commands:
- `x.py check`
- `x.py build`
- `x.py test`
For more suggestions, see https://rustc-dev-guide.rust-lang.org/building/suggested.html
`x.py` will now use the configuration at /home/nilsh/projects/rustfast/src/bootstrap/defaults/config.compiler.toml

Allow building std with cranelift
- Don't pass llvm-specific args when using cranelift
- Don't use `asm` in compiler_builtins when using cranelift
r? `@bjorn3` cc `@Mark-Simulacrum`

The primary motivation is to have the cargo docs show up on https://doc.rust-lang.org/nightly/nightly-rustc/cargo, but as a nice side effect this makes `x doc cargo` work locally.

Make LLD build forward-compatible with LLVM 16
Switch to using the cmake module instead of llvm-config. I believe this also removes the need for llvm-config-wrapper.
|
|
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.
|
|
LLVM does this itself since 606cb8548a1b7763e0c8489c5efe66803a7ede72,
and 14 is no longer the correct standard when building lld 16,
causing build failures.

Remove unused `check-stage2-T-arm-linux-androideabi-H-x86_64-unknown-linux-gnu` make rule
It's not used anywhere in CI, and it seems of questionable use. It was first added in 0e272de69f4a9c889e5f1a024a88b3e1f60cb6c5, which looks like it's just intended for CI, not as a user-facing feature.
