// Passing --emit=dep-info to the Rust compiler should create a .d file...
// but it failed to do so in Rust 1.69.0 when combined with -Z unpretty=expanded
// due to a bug. This test checks that -Z unpretty=expanded does not prevent the
// generation of the dep-info file, and that its -Z unpretty=normal counterpart
// does not get an unexpected dep-info file.
// See https://github.com/rust-lang/rust/issues/112898
