A spanish translation was added in rust-lang/rust-by-example#1910, but the upstream integration was never added.
…ay' in '[_]' and '*mut [_]'; Update feature gate and tracking issue for 'alloc_slice_into_array' items;
… r=Amanieu Stabilize s390x `vector` target feature and `is_s390x_feature_detected!` macro closes rust-lang#145649 closes rust-lang#135413 cc: rust-lang#130869 reference PR: rust-lang/reference#1972 # Stabilization report ## Summary This PR stabilizes the following s390x target features: - `vector` - `vector-enhancements-1` - `vector-enhancements-2` - `vector-enhancements-3` - `vector-packed-decimal` - `vector-packed-decimal-enhancement` - `vector-packed-decimal-enhancement-2` - `vector-packed-decimal-enhancement-3` - `nnp-assist` - `miscellaneous-extensions-2` - `miscellaneous-extensions-3` - `miscellaneous-extensions-4` Additionally, it stabilizes the `std::arch::is_s390x_feature_detected!` macro itself and stably accepts the target features listed above. ## Tests & ABI details Only the `vector` target feature changes the ABI, much like e.g. `avx2` it will, depending on the ABI, pass vector types in vector registers. This behavior is tested extensively: - [tests/assembly-llvm/s390x-vector-abi.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/assembly-llvm/s390x-vector-abi.rs) - [tests/codegen-llvm/s390x-simd.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/assembly-llvm/s390x-vector-abi.rs) - [tests/ui/abi/simd-abi-checks-s390x.rs ](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/ui/abi/simd-abi-checks-s390x.rs ) The remaining features don't influence the ABI, they only influence instruction selection. In stdarch we test that the expected instructions are in fact generated when the target feature is enabled. ## Implementation history For `is_s390x_feature_detected!`: - rust-lang/stdarch#1699 - rust-lang#138275 - rust-lang/stdarch#1720 - rust-lang/stdarch#1832 For `vector` and friends - rust-lang#127506 - rust-lang#135630 - rust-lang#141250 ## Unresolved questions There is a fixme in [tests/ui/abi/simd-abi-checks-s390x.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/ui/abi/simd-abi-checks-s390x.rs): ``` // FIXME: +soft-float itself doesn't set -vector //`@[z13_soft_float]` compile-flags: --target s390x-unknown-linux-gnu -C target-cpu=z13 -C target-feature=-vector,+soft-float //`@[z13_soft_float]` needs-llvm-components: systemz ``` I'm not sure whether that blocks stabilization? --- The implementation first extracts the listed target features into their own `s390x_target_feature_vector` rust feature, and then stabilizes that. best reviewed commit-by-commit r? `@Amanieu` cc `@uweigand` `@taiki-e`

Stabilise `as_array` in `[_]` and `*const [_]`; stabilise `as_mut_array` in `[_]` and `*mut [_]`. Tracking issue: rust-lang#133508 Closes: rust-lang#133508 This PR stabilises the `as_array` and `as_mut_array` associated functions from the `core_slice_as_array` feature gate: ```rust // core::slice impl<T> [T] { pub const fn as_array<const N: usize>(&self) -> Option<&[T; N]>; pub const fn as_mut_array<const N: usize>(&mut self) -> Option<&mut [T; N]>; } // core::ptr impl<T> *const [T] { pub const fn as_array<const N: usize>(self) -> Option<*const [T; N]>; } impl<T> *mut [T] { pub const fn as_mut_array<const N: usize>(self) -> Option<*mut [T; N]>; } ``` It also updates the feature gates and tracking issues for all items associated with the previous `slice_as_array` tracking issue (including these four that are being stabilised). ~~FCP missing.~~
update isolate_highest_one for NonZero<T> ## Rationale Let `x = self` and `m = (((1 as $Int) << (<$Int>::BITS - 1)).wrapping_shr(self.leading_zeros()))` Then the previous code computed `NonZero::new_unchecked(x & m)`. Since `m` has exactly one bit set (the most significant 1-bit of `x`), `(x & m) == m`. Therefore, the masking step was redundant. The shift is safe and does not need wrapping because: * `self.leading_zeros() < $Int::BITS` because `self` is non-zero. * The result of `unchecked_shr` is non-zero, satisfying the `NonZero` invariant. if wrapping happens we would be violating `NonZero` invariants. why this micro optimization? the old code was suboptimal it duplicated `$Int`’s isolate_highest_one logic instead of delegating to it. Since the type already wraps `$Int`, either delegation should be used for clarity or, if keeping a custom implementation, it should be optimized as above.

…-closure, r=JonathanBrouwer Fix suggestion for returning async closures Fixes rust-lang#148493
…, r=yotamofek [rustdoc] Replace `print` methods with functions to improve code readability We have a lot of `print` methods, making it quite tricky to know what the types we're manipulating are. We did something similar with `Clean` trait a few years ago (the first PR was rust-lang#99638, followed by a lot of them). Each commit replaces one type for easier review. r? `````@yotamofek`````
…ttrs, r=JonathanBrouwer re-use `self.get_all_attrs` result for pass indirectly attribute Could be a fix for a potential performance regression reported here rust-lang#144529 (comment). Apparently the regression later disappeared. Nevertheless, this seems like a decent refactor. r? ````@JonathanBrouwer```` (vaguely attribute-related, maybe there are other optimizations to that PR that we're missing)
