// The way test suites run can be modified using configuration flags,
// ignoring certain tests while running others. This test contains two
// functions, one which must run and the other which must not. The standard
// output is checked to verify that the ignore configuration is doing its job,
// and that output is successfully minimized with the --quiet flag.
// See https://github.com/rust-lang/rust/commit/f7ebe23ae185991b0fee05b32fbb3e29b89a41bf
