   1 An undefined atomic operation function was declared.
   2
   3 Erroneous code example:
   4
   5 ```compile_fail,E0092
   6 #![feature(intrinsics)]
   7
   8 extern "rust-intrinsic" {
   9     fn atomic_foo(); // error: unrecognized atomic operation
  10                      //        function
  11 }
  12 ```
  13
  14 Please check you didn't make a mistake in the function's name. All intrinsic
  15 functions are defined in `librustc_codegen_llvm/intrinsic.rs` and in
  16 `libcore/intrinsics.rs` in the Rust source code. Example:
  17
  18 ```
  19 #![feature(intrinsics)]
  20
  21 extern "rust-intrinsic" {
  22     fn atomic_fence(); // ok!
  23 }
  24 ```
