-// RUN: fir-opt %s | tco | FileCheck %s
+// RUN: fir-opt %s | tco -disable-external-name-interop | FileCheck %s
 
----------------
I don't understand why running a `fir-opt` nullary execution is needed.

That's not the right premise. `tco` doesn't need to be in lock-step with the official compiler because it is intended to solve separable problems. I don't want artificial barriers and specious objectives introduced into the test tool. The fact they can be used independently and may produce differing output is actually a good thing.
