+#### Note: this error code is no longer emitted by the compiler.
+
+The length of the platform-intrinsic function `simd_shuffle` wasn't specified.
+
+Erroneous code example:
+
+```ignore (no longer emitted)
+#![feature(platform_intrinsics)]
+
+extern "platform-intrinsic" {
+    fn simd_shuffle<A,B>(a: A, b: A, c: [u32; 8]) -> B;
+    // error: invalid `simd_shuffle`, needs length: `simd_shuffle`
+}
+```
+
+The `simd_shuffle` function needs the length of the array passed as
+last parameter in its name. Example:
+
+```
+#![feature(platform_intrinsics)]
+
+extern "platform-intrinsic" {
+    fn simd_shuffle8<A,B>(a: A, b: A, c: [u32; 8]) -> B;
+}
+```
