This allows compile-time configuration based on this. In the near future we should do this across all RISCV targets, probably, but this cfg is essential for building software usable on these targets.
- Improve the discussion of `unsafe` blocks within `unsafe` functions. - Fix formatting in Appendix A
Split this into two tests, one for LLVM 19 and one for LLVM 20.
LLVM 20 choses a different unroll factor for the loop.

QNX SDP 8.0 comes with newly renamed QNX OS 8.0, so update the page to talk about QNX, QNX Neutrino 7.0, QNX Neutrino 7.1 or QNX OS 8.0. Also actually add a list of target triples.
If the run fails, it should report that and return a non-zero exit status. The simplest way to do that is with `run(..., check=True)`, which raises a `CalledProcessError`.
…rt, r=workingjubilee Support QNX 7.1 with `io-sock`+libstd and QNX 8.0 (`no_std` only) Changes of this pull request: 1. Refactor code for qnx nto targets to share more code in file `nto_qnx.rs` 1. Add support for an additional network stack on nto qnx 7.1. QNX 7.1 supports two network stacks: 1. `io-pkt`, which is default 2. `io-sock`, which is optional on 7.1 but default in QNX 8.0 As one can see in the [io-sock migration notes](https://www.qnx.com/developers/docs/7.1/index.html#com.qnx.doc.neutrino.io_sock/topic/migrate_app.html), this changes the libc API in a way similar to e.g. linux-gnu vs. linux-musl. This change adds a new target which has a different value for `target_env`, so that e.g. libc can distinguish between both APIs. 2. Add initial support for QNX 8.0, thanks to AkhilTThomas. As it turned out, the problem with forking many processes still exists in QNX 8.0. Because if this, we are now using it for any QNX version (i.e. not check for `target_env` anymore).
…abi, r=fmease compiler: Set `target_abi = "ilp32e"` on all riscv32e targets This allows compile-time configuration based on this. In the near future we should do this across all RISCV targets, probably, but this cfg is essential for building software usable on these targets, and they are tier 3 so it seems less of a concern to tweak their definition thusly.
…wiser Fix tests on LLVM 20 For sparcv8plus.rs, duplicate the test for LLVM 19 and LLVM 20. LLVM 20 resolves one of the FIXME in the test. For x86_64-bigint-add.rs split the check lines for LLVM 19 and LLVM 20. The difference in codegen here is due to a difference in unroll factor, which I believe is not what the test is interested in. Fixes rust-lang#132957. Fixes rust-lang#133754.
…ulacrum Fix GDB `OsString` provider on Windows It would throw an exception due to trying to look up `Wtf8Buf.__0`. The field it actually wants is called [`bytes`](https://github.com/rust-lang/rust/blob/b605c65b6eb5fa71783f8e26df69975f9f1680ee/library/std/src/sys_common/wtf8.rs#L134).
…, r=ehuss TRPL: more backward-compatible Edition changes - Improve the discussion of `unsafe` blocks within `unsafe` functions. - Fix formatting in Appendix A - Incorporate line edits to Chapter 17 from NoStarch.
…triddle Remove extra whitespace from rustdoc breadcrumbs for copypasting The docs header used to display [item names with their full path](https://doc.rust-lang.org/1.82.0/std/os/unix/ffi/trait.OsStrExt.html), but a [recent design change](https://doc.rust-lang.org/1.83.0/std/os/unix/ffi/trait.OsStrExt.html) has split the path and added extra styling to it. The problem is the new styling affects how this text is copied to clipboard. I used to copy and paste the paths into `use` statements in the code, but the new styling has extra formatting and whitespace that makes copied text unusable in Rust source code. Instead of: > std::os::unix::ffi::OsStrExt I now get: > std > :: > os > :: > unix > :: > ffi > Trait OsStrExt This change removes extra whitespace from the markup, and removes `display: flex`. Paths (now in small text) are unlikely to be that long to wrap, and even then regular text wrapping should be sufficient.
ci.py: check the return code in `run-local` If the run fails, it should report that and return a non-zero exit status. The simplest way to do that is with `run(..., check=True)`, which raises a `CalledProcessError`.
…rk-Simulacrum Add an `unchecked_div` alias to the `Div<NonZero<_>>` impls Inspired by rust-lang/libs-team#526, if people are looking for `unchecked_div`, point them to `u32: Div<NonZero<u32>>` and friends which do no runtime checks -- and are safe! -- rather than today's behaviour of [the intrinsic being the top result](https://doc.rust-lang.org/std/?search=unchecked_div).

Hmm |
|
I don't believe anything in this rollup can lead to that failure |
|
I wouldn't think so either. I've never used C++ beyond trivial scripts, but it certainly looks like LLVM's code coverage tool itself is failing to compile. I assume that in order to run the tests altered in that PR, llvm-cov gets compiled? That's the only possible connection I could think of, which is why I I suppose we'll find out quite quickly if there's any connection, as there's another rollup being tested at the moment. That rollup is a different, non-overlapping set of PRs compared to this one. |

Ah... That is likely yes. |
|
Hopefully I'm wrong! I'm not familiar with how all of the tools are built, so that very well could be the case. |
|
Yeah, we'll find out soon enough if master is broken, lol |
|
My guess is that this is a flaky bit of memory on the CI runner. It's pointing to a variable declared as |

Damn cosmic rays… |
