   6 Invalid monomorphization of an intrinsic function was used. Erroneous code
   7 example:

   9 ```ignore (error-emitted-at-codegen-which-cannot-be-handled-by-compile_fail)
  10 #![feature(platform_intrinsics)]
  11
  12 extern "platform-intrinsic" {
  13     fn simd_add<T>(a: T, b: T) -> T;
  14 }
  15
  16 fn main() {
  17     unsafe { simd_add(0, 1); }
  18     // error: invalid monomorphization of `simd_add` intrinsic
  19 }

  22 The generic type has to be a SIMD type. Example:
