// This test case makes sure that a change in symbol visibility is detected by
// our dependency tracking. We do this by changing a module's visibility to
// `private` in rpass2, causing the contained function to go from `default` to
// `hidden` visibility.
// The function is marked with #[no_mangle] so it is considered for exporting
// even from an executable. Plain Rust functions are only exported from Rust
// libraries, which our test infrastructure does not support.
