…ier 2 It is not shipped with host tools, so it was located in the wrong group.
Call out early that the results returned can differ across calls / aren't deterministic. This was already mentioned at the bottom of examples, but I think it's worth calling out early, since this caused at least one person (me!) great confusion. [ Added a comma to the docs, reflowed commit message - Trevor ]
…illot Use -Zmir-opt-level=0 in tests for MIR building The mir-opt test suite currently defaults all tests in it to `-Zmir-opt-level=4`, so if a test is trying to test MIR _building_ not optimizations and it is in that directory, it _must_ override the default mir-opt-level.
…t, r=samueltardieu Mention that casting to *const () is a way to roundtrip with from_raw_parts See discussion on rust-lang#81513
…tardieu Fix wrong cache line size of riscv64 see https://go-review.googlesource.com/c/go/+/526659, All of riscv CPU using 64B for cache-line size.
Improve std::fs::read_dir docs Call out early that the results returned can differ across calls / aren't deterministic. This was already mentioned at the bottom of examples, but I think it's worth calling out early, since this caused at least one person (me!) great confusion.
…k-Simulacrum Move WTF-8 code from std into core and alloc This is basically a small portion of rust-lang#129411 with a smaller scope. It *does not*\* affect any public APIs; this code is still internal to the standard library. It just moves the WTF-8 code into `core` and `alloc` so it can be accessed by `no_std` crates like `backtrace`. > \* The only public API this affects is by adding a `Debug` implementation to `std::os::windows::ffi::EncodeWide`, which was not present before. This is due to the fact that `core` requires `Debug` implementations for all types, but `std` does not (yet) require this. Even though this was ultimately changed to be a wrapper over the original type, not a re-export, I decided to keep the `Debug` implementation so it remains useful. Like we do with ordinary strings, the tests are still located entirely in `alloc`, rather than splitting them into `core` and `alloc`. ---- Reviewer note: for ease of review, this is split into three commits: 1. Moving the original files into their new "locations" 2. Actually modifying the code to compile. 3. Removing aesthetic changes that were made so that the diff for commit 2 was readable. You can review commits 1 and 3 to verify these claims, but commit 2 contains the majority of the changes you should care about. ---- API changes: `impl Debug for std::os::windows::ffi::EncodeWide`
…, r=jieyouxu Move `riscv64-gc-unknown-linux-musl` from Tier 2 with Host tools to Tier 2 It is not shipped with host tools, so it was located in the wrong group. The musl target is [here](https://github.com/rust-lang/rust/blob/467c89cd0b1c579edc247808c35941677918d29d/src/ci/docker/host-x86_64/dist-various-2/Dockerfile#L126) - no host tools. Noticed in rust-lang/docker-rust#247.
