# ignore-cross-compile
# 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.
