prefer `compile::stream_cargo` for building tools
Previously, we were running bare commands for `ToolBuild` step and were unable to utilize some of the flags which are already handled by `compile::stream_cargo`.
This change makes `ToolBuild` to use `compile::stream_cargo`, allowing us to benefit from the flags supported by the bootstrap cargo.

check host's libstdc++ version when using ci llvm
If the host's libstdc++ version is too old using ci-llvm may result in an ABI mismatch between the local libstdc++ and libLLVM.so. This PR adds a sanity check to immediately fail at the beginning of the bootstrap before starting the actual build. I am not sure if '8' is the best threshold, but it should be a good start and we can increase it anytime if needed.
Fixes#123037
Add translation support by mdbook-i18n-helpers to bootstrap
This PR add translation support by [mdbook-i18n-helpers](https://github.com/google/mdbook-i18n-helpers) to bootstrap.
This is draft PR because there is the dependency to my forked mdbook-i18n-helpers.
If this PR is acceptable, I'll send a PR to the original mdbook-i18n-helpers and remove draft after changing the dependency to the original.
Closes#124641
delete bootstrap build before switching to bumped rustc
Technically, wiping bootstrap builds can increase the build time. But in practice, trying to manually resolve post-bump issues and even accidentally removing the entire build directory will result in a much greater loss of time. After all, the bootstrap build process is not a particularly lengthy operation.
Workaround for #125578
Some of the bootstrap logics should be ignored during unit tests because they either
make the tests take longer or cause them to fail. Therefore we need to be able to exclude
them from the bootstrap when it's called by unit tests. This change introduces a new feature
called `bootstrap-self-test`, which is enabled on bootstrap unit tests by default. This allows
us to keep the logic separate between compiler builds and bootstrap tests without needing messy
workarounds (like checking if target names match those in the unit tests).

As of https://github.com/rust-lang/rust/pull/125408 PR,
rustbook now relies on dependencies from the "src/doc/book" submodule.
However, bootstrap does not automatically sync this submodule before reading
metadata informations. And if the submodule is not present, reading
metadata will fail because rustbook's dependencies will be missing.
This change makes "src/doc/book" to be fetched/synced automatically
before trying to read metadata.

Streamline `x fmt` and improve its output
- Removes the ability to pass paths to `x fmt`, because it's complicated and not useful, and adds `--all`.
- Improves `x fmt` output.
- Improves `x fmt`'s internal code.
r? ``@GuillaumeGomez``
Currently, `x fmt` can print two lists of files.
- The untracked files that are skipped. Always done if within a git
repo.
- The modified files that are formatted.
But if you run with `--all` (or with `GITHUB_ACTIONS=true`) it doesn't
print anything about which files are formatted.
This commit increases consistency.
- The formatted/checked files are now always printed. And it makes it clear why
a file was formatted, e.g. with "modified".
- It uses the same code for both untracked files and formatted/checked
files. This means that now if there are a lot of untracked files just
the number will be printed, which is like the old behaviour for
modified files.
Example output:
```
fmt: skipped 31 untracked files
fmt: formatted modified file compiler/rustc_mir_transform/src/instsimplify.rs
fmt: formatted modified file compiler/rustc_mir_transform/src/validate.rs
fmt: formatted modified file library/core/src/ptr/metadata.rs
fmt: formatted modified file src/bootstrap/src/core/build_steps/format.rs
```
or (with `--all`):
```
fmt: checked 3148 files
```
- Precede them all with `fmt` so it's clear where they are coming from.
- Use `error:` and `warning:` when appropriate.
- Print warnings to stderr instead of stdout
By default, `x fmt` formats/checks modified files. But it also lets you
choose one or more paths instead.
This adds significant complexity to `x fmt`. Explicit paths are
specified via `WalkBuilder::add` rather than `OverrideBuilder::add`. The
`ignore` library is not simple, and predicting the interactions between
the two mechanisms is difficult.
Here's a particularly interesting case.
- You can request a path P that is excluded by the `ignore` list in the
`rustfmt.toml`. E.g. `x fmt tests/ui/` or `x fmt tests/ui/bitwise.rs`.
- `x fmt` will add P to the walker (via `WalkBuilder::add`), traverse it
(paying no attention to the `ignore` list from the `rustfmt.toml`
file, due to the different mechanism), and call `rustfmt` on every
`.rs` file within it.
- `rustfmt` will do nothing to those `.rs` files, because it *also*
reads `rustfmt.toml` and sees that they match the `ignore` list!
It took me *ages* to debug and understand this behaviour. Not good!
`x fmt` even lets you name a path below the current directory. This was
intended to let you do things like `x fmt std` that mirror things like
`x test std`. This works by looking for `std` and finding `library/std`,
and then formatting that. Unfortuantely, this motivating case now gives
an error. When support was added in #107944, `library/std` was the only
directory named `std`. Since then, `tests/ui/std` was added, and so `x
fmt std` now gives an error.
In general, explicit paths don't seem particularly useful. The only two
cases `x fmt` really needs are:
- format/check the files I have modified (99% of uses)
- format/check all files
(While respecting the `ignore` list in `rustfmt.toml`, of course.)
So this commit moves to that model. `x fmt` will now give an error if
given an explicit path. `x fmt` now also supports a `--all` option. (And
running with `GITHUB_ACTIONS=true` also causes everything to be
formatted/checked, as before.) Much simpler!
Support `./x doc run-make-support --open`
Having easy access to the run-make-support documentation is invaluable when creating run-make tests using the new Rust recipes.
Make more of the test suite run on Mac Catalyst
Combined with https://github.com/rust-lang/rust/pull/125225, the only failing parts of the test suite are in `tests/rustdoc-js`, `tests/rustdoc-js-std` and `tests/debuginfo`. Tested with:
```console
./x test --target=aarch64-apple-ios-macabi library/std
./x test --target=aarch64-apple-ios-macabi --skip=tests/rustdoc-js --skip=tests/rustdoc-js-std --skip=tests/debuginfo tests
```
Will probably put up a PR later to enable _running_ on (not just compiling for) Mac Catalyst in CI, though not sure where exactly I should do so? `src/ci/github-actions/jobs.yml`?
Note that I've deliberately _not_ enabled stack overflow handlers on iOS/tvOS/watchOS/visionOS (see https://github.com/rust-lang/rust/issues/25872), but rather just skipped those tests, as it uses quite a few APIs that I'd be weary about getting rejected by the App Store (note that Swift doesn't do it on those platforms either).
r? ``@workingjubilee``
CC ``@thomcc``
``@rustbot`` label O-ios O-apple
This adds the `only-apple`/`ignore-apple` compiletest directive, and
uses that basically everywhere instead of `only-macos`/`ignore-macos`.
Some of the updates in `run-make` are a bit redundant, as they use
`ignore-cross-compile` and won't run on iOS - but using Apple in these
is still more correct, so I've made that change anyhow.
It's reasonable to want to, but in the current implementation this
causes multiple problems.
- All the `rmake.rs` files are formatted every time even when they
haven't changed. This is because they get whitelisted unconditionally
in the `OverrideBuilder`, before the changed files get added.
- The way `OverrideBuilder` works, if any files gets whitelisted then no
unmentioned files will get traversed. This is surprising, and means
that the `rmake.rs` entries broke the use of explicit paths to `x
fmt`, and also broke `GITHUB_ACTIONS=true git check --fmt`.
The commit removes the `rmake.rs` entries, fixes the formatting of a
couple of files that were misformatted (not previously caught due to the
`GITHUB_ACTIONS` breakage), and bans `!`-prefixed entries in
`rustfmt.toml` because they cause all these problems.
Some are too long, some aren't complete sentences, some are complete
sentences but don't bother with an upper case letter at the start. All
annoying and hurt readability.
Run rustfmt on files that need it.
Somehow these files aren't properly formatted. By default `x fmt` and `x tidy` only check files that have changed against master, so if an ill-formatted file somehow slips in it can stay that way as long as it doesn't get modified(?)
I found these when I ran `x fmt` explicitly on every `.rs` file in the repo, while working on
https://github.com/rust-lang/compiler-team/issues/750.

refactor: add rustc-perf submodule to src/tools
Currently, it's very challenging to perform a sandboxed `opt-dist`
bootstrap because the tool requires `rustc-perf` to be present, but
there is no proper management/tracking of it. Instead, a specific commit
is hardcoded where it is needed, and a non-checksummed zip is fetched
ad-hoc. This happens in two places:
`src/ci/docker/host-x86_64/dist-x86_64-linux/Dockerfile`:
```dockerfile
ENV PERF_COMMIT 4f313add609f43e928e98132358e8426ed3969ae
RUN curl -LS -o perf.zip https://ci-mirrors.rust-lang.org/rustc/rustc-perf-$PERF_COMMIT.zip && \
unzip perf.zip && \
mv rustc-perf-$PERF_COMMIT rustc-perf && \
rm perf.zip
```
`src/tools/opt-dist/src/main.rs`
```rust
// FIXME: add some mechanism for synchronization of this commit SHA with
// Linux (which builds rustc-perf in a Dockerfile)
// rustc-perf version from 2023-10-22
const PERF_COMMIT: &str = "4f313add609f43e928e98132358e8426ed3969ae";
let url = format!("https://ci-mirrors.rust-lang.org/rustc/rustc-perf-{PERF_COMMIT}.zip");
let client = reqwest::blocking::Client::builder()
.timeout(Duration::from_secs(60 * 2))
.connect_timeout(Duration::from_secs(60 * 2))
.build()?;
let response = retry_action(
|| Ok(client.get(&url).send()?.error_for_status()?.bytes()?.to_vec()),
"Download rustc-perf archive",
5,
)?;
```
This causes a few issues:
1. Maintainers need to be careful to bump PERF_COMMIT in both places
every time
2. In order to run `opt-dist` in a sandbox, you need to provide your own
`rustc-perf` (https://github.com/rust-lang/rust/pull/125125), but to
figure out which commit to provide you need to grep the Dockerfile
3. Even if you manage to provide the correct `rustc-perf`, its
dependencies are not included in the `vendor/` dir created during
`dist`, so it will fail to build from the published source tarballs
4. It is hard to provide any level of automation around updating the
`rustc-perf` in use, leading to staleness
Fundamentally, this means `rustc-src` tarballs no longer contain
everything you need to bootstrap Rust, and packagers hoping to leverage
`opt-dist` need to go out of their way to keep track of this "hidden"
dependency on `rustc-perf`.
This change adds rustc-perf as a git submodule, pinned to the current
`PERF_COMMIT` 4f313add609f43e928e98132358e8426ed3969ae. Subsequent
commits ensure the submodule is initialized when necessary, and make use
of it in `opt-dist`.
Remove unnecessary -fembed-bitcode usage now that it's deprecated
This is a partial revert of 6d819a4b8f because https://github.com/rust-lang/cc-rs/pull/812 removed this flag entirely, meaning we shouldn't have to pass this manually anymore
