E0442: r##"
Intrinsic argument(s) and/or return value have the wrong length.
Erroneous code example:
```
#[repr(simd)]
struct i8x16(i8, i8, i8, i8, i8, i8, i8, i8,
i8, i8, i8, i8, i8, i8, i8, i8);
#[repr(simd)]
struct i32x4(i32, i32, i32, i32);
#[repr(simd)]
struct i64x2(i64, i64);
extern "platform-intrinsic" {
fn x86_mm_adds_epi16(x: i8x16, y: i32x4) -> i64x2;
// error: intrinsic arguments/return value have wrong length
}
```
To fix this error, please refer to the function declaration to give
it the awaited types with the awaited length. Example:
```
#[repr(simd)]
struct i16x8(i16, i16, i16, i16, i16, i16, i16, i16);
extern "platform-intrinsic" {
fn x86_mm_adds_epi16(x: i16x8, y: i16x8) -> i16x8; // ok!
}
