Support repr(simd) on ADTs containing a single array field This is a squash and rebase of `@gnzlbg's` #63531 I've never actually written code in the compiler before so just fumbled my way around until it would build 😅 I imagine there'll be some work we need to do in `rustc_codegen_cranelift` too for this now, but might need some input from `@bjorn3` to know what that is. cc `@rust-lang/project-portable-simd` ----- This PR allows using `#[repr(simd)]` on ADTs containing a single array field: ```rust #[repr(simd)] struct S0([f32; 4]); #[repr(simd)] struct S1<const N: usize>([f32; N]); #[repr(simd)] struct S2<T, const N: usize>([T; N]); ``` This should allow experimenting with portable packed SIMD abstractions on nightly that make use of const generics. |
