test/stdlib/ReflectionHashing.swift

// RUN: %target-build-swift -module-name a %s -o %t.out
// RUN: %target-run %t.out
// REQUIRES: executable_test

// This test expects consistent hash code generation. However String instance
// generate different values on Linux depending on which version of libicu is
// installed. Therefore we run this test only on non-linux OSes, which is
// best described as having objc_interop.

// REQUIRES: objc_interop

//
// This file contains reflection tests that depend on hash values.
// Don't add other tests here.
