| The type of the field in a tuple struct isn't an array when using the `#[simd]` | |
| attribute. | |
| Erroneous code example: | |
| ```compile_fail,E0076 | |
| #![feature(repr_simd)] | |
| #[repr(simd)] | |
| struct Bad(u16); // error! | |
| ``` | |
| When using the `#[simd]` attribute to automatically use SIMD operations in tuple | |
| structs, if you want a single-lane vector then the field must be a 1-element | |
| array, or the compiler will trigger this error. | |
| Fixed example: | |
| ``` | |
| #![feature(repr_simd)] | |
| #[repr(simd)] | |
| struct Good([u16; 1]); // ok! | |
| ``` |
