#### Note: this error code is no longer emitted by the compiler.
An intrinsic was declared without being a function.
Erroneous code example:
```ignore (no longer emitted)
#![feature(intrinsics)]
#![allow(internal_features)]
extern "C" {
#[rustc_intrinsic]
pub static atomic_singlethreadfence_seqcst: unsafe fn();
// error: intrinsic must be a function
}
fn main() { unsafe { atomic_singlethreadfence_seqcst(); } }
```
An intrinsic is a function available for use in a given programming language
whose implementation is handled specially by the compiler. In order to fix this
error, just declare a function. Example:
```ignore (no longer emitted)
#![feature(intrinsics)]
#![allow(internal_features)]
#[rustc_intrinsic]
pub unsafe fn atomic_singlethreadfence_seqcst(); // ok!
fn main() { unsafe { atomic_singlethreadfence_seqcst(); } }
```
