    rust-lang#120675 introduced a new mechanism to declare intrinsics which will potentially replace the rust-intrinsic ABI. The new mechanism introduces a placeholder body and mark the intrinsic with #[rustc_intrinsic_must_be_overridden]. In practice, this means that backends should not generate code for the placeholder, and shim the intrinsic. The new annotation is an internal compiler implementation, and it doesn't need to be exposed to StableMIR users. In this PR, intrinsics marked with `rustc_intrinsic_must_be_overridden` are handled the same way as intrinsics that do not have a body.
I didn't find `crt-static` at first (for `x86_64-unknown-linux-gnu`), because it was put at the bottom the large and otherwise sorted list. Fully sort the list before we print it. Note that `llvm_target_features` starts out sorted and does not need to be sorted an extra time.
This excludes casting, which needs more tests.
Add a spot that was missed in <rust-lang#121997>.
Const eval negation was added. This test is now covered by Miri tests, and merged into an existing UI test. Fixes <rust-lang#124583>
These changes bring it closer to other standard library documentation and, in particular, `std::fs::canonicalize`, which it will often be compared with. * Add `# Platform-specific behavior` section, with content moved from Examples section. * Create `# Errors` section. * Phrase error description to allow future platforms to have new syntactic errors, rather than only emptiness. * Add missing commas. * Indent example code 4 spaces.

…not-hide, r=Kobzol Migrate `inaccessible-temp-dir`, `output-with-hyphens` and `issue-10971-temps-dir` `run-make` tests to `rmake` Part of rust-lang#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
…li-obk Unify intrinsics body handling in StableMIR rust-lang#120675 introduced a new mechanism to declare intrinsics which will potentially replace the rust-intrinsic ABI. The new mechanism introduces a placeholder body and mark the intrinsic with `#[rustc_intrinsic_must_be_overridden]`. In practice, this means that a backend should not generate code for the placeholder, and shim the intrinsic. The new annotation is an internal compiler implementation, and it doesn't need to be exposed to StableMIR users. In this PR, we unify the interface for intrinsics marked with `rustc_intrinsic_must_be_overridden` and intrinsics that do not have a body.

…r=Amanieu Add `f16` and `f128` inline ASM support for `x86` and `x86-64` This PR adds `f16` and `f128` input and output support to inline ASM on `x86` and `x86-64`. `f16` vector sizes are taken from [here](https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html). Relevant issue: rust-lang#125398 Tracking issue: rust-lang#116909 `@rustbot` label +F-f16_and_f128
 Also sort `crt-static` in `--print target-features` output
I didn't find `crt-static` at first (for `x86_64-unknown-linux-gnu`), because it was put at the bottom of the large and otherwise sorted list.
Fully sort the list before we print it.
Note that `llvm_target_features` starts out and remains sorted and does not need to be sorted an extra time.

End support for Python 3.8 in tidy Python 3.8 will reach its end of support in October 2024. You can find more details [here](https://devguide.python.org/versions/). ### NixOS NixOS has already discontinued provide Python 3.8.
