// 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.
