This commit adds some documentation about the state of `-Cpanic=unwind` for the following wasm targets: * `wasm32-unknown-unknown` * `wasm32-wasip1` * `wasm32-wasip2` * `wasm32v1-none` Notably it's possible to use `-Cpanic=unwind` with `-Zbuild-std` and it's also mentioned that there are no concrete proposals at this time to adding a new set of targets which support unwinding. My hunch is that in a few years' time it would make sense to enable it by default on these targets (except for `wasm32v1-none`) but that's a problem for future folks to debate. For now this is an attempt to document the status quo.
…narycat,fmease [rustdoc] Correctly handle `should_panic` doctest attribute and fix `--no-run` test flag on the 2024 edition Fixes rust-lang#143009. Fixes rust-lang#143858. Since it includes fixes from rust-lang#143453, it's taking it over (commits 2, 3 and 4 are from rust-lang#143453). For `--no-run`, we forgot to check the "global" options in the 2024 edition, fixed in the first commit. For `should_panic` fix, the exit code check has been fixed. cc `@TroyKomodo` (thanks so much for providing such a complete test, made my life a lot easier!) r? `@notriddle`
…json, r=fmease Fix doctest output json Fixes rust-lang#144798. Hopefully it will work with the new changes in `libtest` without needing to do both at once. This PR moves the `rustdoc` merged doctest extra information directly into `libtest` to ensure they share the same rendering to prevent the bug uncovered in rust-lang#144798. cc `@lolbinary` (as you reviewed the first PR) And since we're making changes to `libtest`: r? `@Amanieu`
…r=jieyouxu Add documentation about unwinding to wasm targets This commit adds some documentation about the state of `-Cpanic=unwind` for the following wasm targets: * `wasm32-unknown-unknown` * `wasm32-wasip1` * `wasm32-wasip2` * `wasm32v1-none` Notably it's possible to use `-Cpanic=unwind` with `-Zbuild-std` and it's also mentioned that there are no concrete proposals at this time to adding a new set of targets which support unwinding.

Implement non-poisoning `Mutex::with_mut`, `RwLock::with` and `RwLock::with_mut` ACP: rust-lang/libs-team#497.
Make `fmt::Write` a diagnostic item I'm working on an enhancement to [`clippy::format_push_string`](https://rust-lang.github.io/rust-clippy/master/index.html#format_push_string), which would suggest an autofix to replace `push_str`/`+=` with `write!`. But that could require importing `std::fmt::Write`, and so I need this diagnostic item to check if it's already in scope. The reason I called it `FmtWrite` and not just `Write` is that there's already an `IoWrite` defined.
…=Noratrieb Improve the advice given by panic_immediate_abort Now that rust-lang#147338 is merged, users should consider using the Cargo support for immediate-aborting panics.
