// 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.
