exit: document interaction with C Cc rust-lang#126600

…youxu Leave a breadcrumb towards bootstrap config documentation in `bootstrap.toml` I was curious as to the possible bootstrap options I can put in config.toml, but had some trouble figuring it out. There is no obvious documentation in `config.toml` (obviously), the documentation in src/bootstrap/defaults is *nice*, but also rather sparse, by design. I had to dive into the parsing code, and stuble upon [a very helpful doc comment](https://github.com/rust-lang/rust/blob/30f168ef811aec63124eac677e14699baa9395bd/src/bootstrap/src/core/config/config.rs#L181) there to realize that `config.example.toml` *exists*, and that it does, indeed, answer all of my questions. So I figured it might be worth making this journey a bit easier for future contributors and add mention the `config.example.toml` directly in `config.toml`. Now, since rust-lang#137081 is in-flight which would rename `config(.example)?.toml` to `bootstrap(.example)?.toml`, I figure it's better to wait until that one lands, and submit the "new", "correct" filename upfront, instead of landing `config.toml` now and updating it to `boostrap.toml` later. `@rustbot` blocked rust-lang#137081

…rmit, r=tgross35 Implement `read_buf` for Hermit Following hermit-os/kernel#1606, it is now safe to implement `Read::read_buf` for file descriptors on Hermit. cc ```@mkroening```

…laumeGomez rustdoc-json: Add tests for `#[repr(...)]` Works towards rust-lang#137645 and rust-lang#81359 Based on rust-lang#138018, but with only the test changes. CC ```@obi1kenobi``` r? ```@GuillaumeGomez```

…ler-errors Extract `for_each_immediate_subpat` from THIR pattern visitors This is extracted from some larger changes I've been working on, trying to introduce a “THIR pattern id” to refer to THIR pattern nodes without a direct reference. The future of those changes is somewhat uncertain, due to some [proposed changes involving upvar inference](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/upvar.20inference.20on.20THIR.3F). So I'm taking my preparatory changes that make sense on their own, and extracting them into one or more independent PRs. --- This particular patch takes two different functions that were both matching on `PatKind` to traverse subpatterns, and extracts the core match into a single helper function.

Unvacation myself Feeling better now. r? ghost

…rcote Add `#[cfg(test)]` for Transition in dfa in `rustc_transmute` `Transition` is only used in the `Transitions::insert` in test after rust-lang#137776 Detected by rust-lang#128637

Hey friends of Fuchsia! This issue could use some guidance on how this should be
resolved/implemented on Fuchsia. Could one of you weigh in?

This looks very similar to #138661 (comment) but with a different git submodule missing files.
