2024-07-24Do not use question as labelEsteban Küber-2/+2
We don't want to have questions in the diagnostic output. Instead, we use wording that communicates uncertainty, like "might": ``` error[E0432]: unresolved import `spam` --> $DIR/import-from-missing-star-3.rs:2:9 | LL | use spam::*; | ^^^^ you might be missing crate `spam` | = help: consider adding `extern crate spam` to use the `spam` crate ```

r=workingjubilee Make repr(packed) vectors work with SIMD intrinsics In #117116 I fixed `#[repr(packed, simd)]` by doing the expected thing and removing padding from the layout. This should be the last step in providing a solution to rust-lang/portable-simd#319

2024-04-03rename `expose_addr` to `expose_provenance`joboet-2/+2
2024-04-02Rollup merge of #122935 - RalfJung:with-exposed-provenance, r=AmanieuJacob Pratt-3/+3
rename ptr::from_exposed_addr -> ptr::with_exposed_provenance As discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/To.20expose.20or.20not.20to.20expose/near/427757066). The old name, `from_exposed_addr`, makes little sense as it's not the address that is exposed, it's the provenance. (`ptr.expose_addr()` stays unchanged as we haven't found a better option yet. The intended interpretation is "expose the provenance and return the address".) The new name nicely matches `ptr::without_provenance`.

2024-03-14Rollup merge of #122287 - RalfJung:simd-static-assert, r=pnkfelixMatthias Krüger-0/+41
add test ensuring simd codegen checks don't run when a static assertion failed stdarch relies on this to ensure that SIMD indices are in bounds. I would love to know why this works, but I can't figure out where codegen decides to not codegen a function if a required-const does not evaluate. `@oli-obk` `@bjorn3` do you have any idea?
2024-03-11Update test directives for `wasm32-wasip1`Alex Crichton-1/+1
* The WASI targets deal with the `main` symbol a bit differently than native so some `codegen` and `assembly` tests have been ignored. * All `ignore-emscripten` directives have been updated to `ignore-wasm32` to be more clear that all wasm targets are ignored and it's not just Emscripten. * Most `ignore-wasm32-bare` directives are now gone. * Some ignore directives for wasm were switched to `needs-unwind` instead. * Many `ignore-wasm32*` directives are removed as the tests work with WASI as opposed to `wasm32-unknown-unknown`.

2024-02-22Auto merge of #121225 - RalfJung:simd-extract-insert-const-idx, ↵bors-33/+8
r=oli-obk,Amanieu require simd_insert, simd_extract indices to be constants As discussed in https://github.com/rust-lang/rust/issues/77477 (see in particular [here](https://github.com/rust-lang/rust/issues/77477#issuecomment-703149102)). This PR doesn't touch codegen yet -- the first step is to ensure that the indices are always constants; the second step is to then make use of this fact in backends. Blocked on https://github.com/rust-lang/stdarch/pull/1530 propagating to the rustc repo.
