rust/tests/incremental/spike-neg2.rs

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

// revisions:rpass1 rpass2
// should-fail
