+An undefined atomic operation function was declared.
+
+Erroneous code example:
+
+```compile_fail,E0092
+#![feature(intrinsics)]
+
+extern "rust-intrinsic" {
+    fn atomic_foo(); // error: unrecognized atomic operation
+                     //        function
+}
+```
+
+Please check you didn't make a mistake in the function's name. All intrinsic
+functions are defined in `compiler/rustc_codegen_llvm/src/intrinsic.rs` and in
+`library/core/src/intrinsics.rs` in the Rust source code. Example:
+
+```
+#![feature(intrinsics)]
+
+extern "rust-intrinsic" {
+    fn atomic_fence(); // ok!
+}
+```
