// Splatter test case. This is gross, but it works for now. For the
// driver, just getting coverage of the tool code and checking the

// output. Intended changes should add more reasonable test cases, and
// just update this test to match the expected behavior.
//
// Note that at conception, this exactly matches gcc.
