+All types in a tuple struct aren't the same when using the `#[simd]`
+attribute.
+
+Erroneous code example:
+
+```compile_fail,E0076
+#![feature(repr_simd)]
+
+#[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:
+
+```
+#![feature(repr_simd)]
+
+#[repr(simd)]
+struct Good(u32, u32, u32, u32); // ok!
+```
