   1 // A variant of the first "spike" test that serves to test the
   2 // `rustc_partition_reused` and `rustc_partition_codegened` tests.
   3 // Here we change and say that the `y` module will be codegened (when
   4 // in fact it will not), and then indicate that the test itself
   5 // should-fail (because an error will be reported, and hence the
   6 // revision rpass2 will not compile, despite being named rpass).
   7
   8 // revisions:rpass1 rpass2
   9 // should-fail
