   4 Invalid monomorphization of an intrinsic function was used. Erroneous code
   5 example:
   6
   7 ```ignore (error-emitted-at-codegen-which-cannot-be-handled-by-compile_fail)
   8 #![feature(platform_intrinsics)]
   9
  10 extern "platform-intrinsic" {
  11     fn simd_add<T>(a: T, b: T) -> T;
  12 }
  13
  14 fn main() {
  15     unsafe { simd_add(0, 1); }
  16     // error: invalid monomorphization of `simd_add` intrinsic
  17 }
  18 ```
  19
  20 The generic type has to be a SIMD type. Example:
  21
  22 ```
  23 #![feature(repr_simd)]
  24 #![feature(platform_intrinsics)]
  25
  26 #[repr(simd)]
  27 #[derive(Copy, Clone)]
  28 struct i32x2(i32, i32);

  30 extern "platform-intrinsic" {
  31     fn simd_add<T>(a: T, b: T) -> T;
  32 }
  33
  34 unsafe { simd_add(i32x2(0, 0), i32x2(1, 2)); } // ok!
