| // 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. |
