Add `--no-capture`/`--nocapture` as bootstrap arguments
I often try `x test ... --nocapture` => 'unknown argument' => `x test ... -- --nocapture`. As we forward several other compiletest flags, let's recognise this one in bootstrap as well.
compiletest: Remove empty 'expected' files when blessing
Fixes#134793Fixes#134196
This also refactors `compare_output` to return an enum; returning a usize was done for convenience but is misleading
Sort triples by name in platform_support.md
When looking for riscv32emc support, I missed it at first because it was at the end of the tier3 target list [here](https://doc.rust-lang.org/rustc/platform-support.html#tier-3). These lists are *mostly* dictionary sorted so I assumed it should be near the riscv32i* targets.
This PR puts all targets back in dictionary order. There were only a few outside of tier3.
I ended up writing a small program to sort them because I did not trust myself to do it manually, but I stopped short of fully automating it.
I have manually reviewed the output to confirm it still has the same number of entries, and that the changed values do follow the ordering I would expect.
For folks who would prefer to review code than manual textual changes, the sorting program (including inputs) is [here.](https://github.com/9names/platform_sort_arch/blob/main/src/main.rs)
rustdoc: use shorter paths as preferred canonical paths
This is a solution to [the `std::sync::poison` linking problem](https://github.com/rust-lang/rust/pull/134692#issuecomment-2560373308), and, in general, makes intra-doc links shorter and clearer.
> Done. This helped with the search, but not with the things like `MutexGuard`'s doc's reference to `Mutex::lock` being converted to the absolute (unstable) `std::sync::poison::Mutex` path.

Migrate `incr-add-rust-src-component` to rmake
This PR partially supersedes #128562, and ports the Makefile-based `tests/run-make/incr-add-rust-src-component` to use rmake.rs infra.
Part of #121876.
This run-make test is a regression test for https://github.com/rust-lang/rust/issues/70924. It (tries to) checks that if we add the `rust-src` component in between two incremental compiles, that the compiler doesn't ICE on the second invocation.
- Original issue:https://github.com/rust-lang/rust/issues/70924
- Fix PR: https://github.com/rust-lang/rust/pull/72767
- PR adding this regression test: https://github.com/rust-lang/rust/pull/72952
However, the Makefile version of this used `$SYSROOT/lib/rustlib/src/rust/src/libstd/lib.rs`, but that actually got moved around and reorganized over the years. As of Dec 2024, the `rust-src` component is more like (specific for our purposes):
```
$SYSROOT/lib/rustlib/src/rust/
library/std/src/lib.rs
src/
```
However, this run-make test is ancient and it exercises incr-comp system logic. I'm not sure if this test would actually catch the original regression.

compiletest: Support `forbid-output` in UI tests
The `forbid-output` directive is currently only run in incremental tests (although no incremental tests use it). There are some UI tests 'using' it, but it's doing nothing 😄 Let's fix this
Will also PR the dev guide to note this.

Begin to implement type system layer of unsafe binders
Mostly TODOs, but there's a lot of match arms that are basically just noops so I wanted to split these out before I put up the MIR lowering/projection part of this logic.

Generate shell completions for x as well
It would be nice to be have shell completions for both `./x` and `x` (installed with `cargo install --path src/tools/x`) instead of just `x.py`. This pr generates the corresponding completions for each shell in a similar way to `x.py` but under `x.<shell>` instead.

Document the `--dev` flag for `src/ci/docker/run.sh`
This flag is very helpful for debugging CI issues locally, but it's not documented anywhere and I wasn't aware of it until `@jieyouxu` pointed it out. Add a note to the CI Docker readme to make this more discoverable
opt-dist: propagate channel info to bootstrap
Fixes#133503.
Previously, `tests/ui/bootstrap/rustc_bootstap.rs` [sic] failed during [beta bump](https://github.com/rust-lang/rust/pull/133447#issuecomment-2501298794) in opt-dist tests. This is because:
- `opt-dist` tried to run `./x test` against beta-channel dist `rustc` through `bootstrap`.
- The dist build produced during the beta bump produces a `rustc` which correctly thinks that it is a beta compiler based on `src/ci/channel` info.
- `opt-dist` tries to run `./x test` on the beta `rustc` from the dist build, but without specifying channel through a synthetic `config.toml`, so `bootstrap` tells `compiletest` that we're on the `nightly` channel (by default).
- Now there's a channel mismatch: `compiletest` believes the `rustc` under test is a *nightly* rustc, but the `rustc` under test actually considers itself a *beta* rustc. This means that `//@ only-nightly` will be satisfied yet the test will fail as the *beta* rustc is not a *nightly* rustc.
This PR:
- Fixes the test failure during beta bump (i.e. #133503) by having `opt-dist` faithfully report the channel of the dist `rustc` being tested (i.e. "beta" in a beta bump PR). This will properly make the test be ignored during beta bump as the `rustc` under test is not a *nightly* rustc.
- Fixes the test name `rustc_bootstap.rs` -> `rustc_bootstrap.rs`. No more stapping.
- Slightly adjusts the doc comment in the test to make it more clear.
I ran a try-job against the beta branch (explicitly running the opt-dist tests by modifying the job definition) with these changes in #134131, and it appears that the try-job was [successful](https://github.com/rust-lang/rust/pull/134131#issuecomment-2555492215). The two commits in this PR are cherry-picked from #134131, with the test commit slightly modified (to also adjust the test comments).
