| # This test makes sure all generic instances get re-exported from Rust dylibs for use by |
| # `-Zshare-generics`. There are two rlibs (`instance_provider_a` and `instance_provider_b`) |
| # which both provide an instance of `Cell<i32>::set`. There is `instance_user_dylib` which is |
| # supposed to re-export both these instances, and then there are `instance_user_a_rlib` and |
| # `instance_user_b_rlib` which each rely on a specific instance to be available. |
| # |
| # In the end everything is linked together into `linked_leaf`. If `instance_user_dylib` does |
| # not export both then we'll get an `undefined reference` error for one of the instances. |
| # |
| # This is regression test for https://github.com/rust-lang/rust/issues/67276. |
