3 # Test to make sure that reachable extern fns are always available in final
4 # productcs, including when LTO is used. In this test, the `foo` crate has a
5 # reahable symbol, and is a dependency of the `bar` crate. When the `bar` crate
6 # is compiled with LTO, it shouldn't strip the symbol from `foo`, and that's the
7 # only way that `foo.c` will successfully compile.
