  11 // A variant of the first "spike" test that serves to test the
  12 // `rustc_partition_reused` and `rustc_partition_translated` tests.
  13 // Here we change and say that the `y` module will be translated (when
  14 // in fact it will not), and then indicate that the test itself
  15 // should-fail (because an error will be reported, and hence the
  16 // revision rpass2 will not compile, despite being named rpass).
