# Error code E0076

All types in a tuple struct aren't the same when using the `#[simd]` attribute.

Erroneous code example:

    #![allow(unused)]
    #![feature(repr_simd)]

    fn main() {
    #[repr(simd)]
    struct Bad(u16, u32, u32 u32); // error!
    }

When using the `#[simd]` attribute to automatically use SIMD operations in tuple struct, the types in the struct must all be of the same type, or the compiler will trigger this error.

Fixed example:

    #![allow(unused)]
    #![feature(repr_simd)]

    fn main() {
    #[repr(simd)]
    struct Good(u32, u32, u32, u32); // ok!
    }
