 // FIXME(workingjubilee): add revisions and generalize to other platform-specific varargs ABIs,
 // preferably after the only-arch directive is enhanced with an "or pattern" syntax
+// NOTE: This deliberately tests an ABI that supports varargs, so no `extern "rust-invalid"`
 //@ only-x86_64
 
 // We have to use this flag to force ABI computation of an invalid ABI
