   1 The length of the platform-intrinsic function `simd_shuffle`
   2 wasn't specified. Erroneous code example:
   3
   4 ```compile_fail,E0439
   5 #![feature(platform_intrinsics)]
   6
   7 extern "platform-intrinsic" {
   8     fn simd_shuffle<A,B>(a: A, b: A, c: [u32; 8]) -> B;
   9     // error: invalid `simd_shuffle`, needs length: `simd_shuffle`
  10 }
  11 ```
  12
  13 The `simd_shuffle` function needs the length of the array passed as
  14 last parameter in its name. Example:
  15
  16 ```
  17 #![feature(platform_intrinsics)]
  18
  19 extern "platform-intrinsic" {
  20     fn simd_shuffle8<A,B>(a: A, b: A, c: [u32; 8]) -> B;
  21 }
  22 ```
