// If a dylib is being produced, the compiler will first check to see if it can
|
|
// be created entirely statically before falling back to dynamic dependencies. This
|
|
// behavior can be overridden with `-C prefer-dynamic`.
|
|
// In this test, bar depends on foo and is compiled fully statically despite the available
|
|
// `foo` dynamic library. This allows the main binary to be executed in the final step.
