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