Tests in this directory are for functionality that has changed in GCC from one release to another or that is not ABI-compliant and may change in a future release. Each test header for changed behavior should indicate the version in which the behavior changed, in order to help users of these tests to determine whether a test failure is expected or not. Every test in this directory that covers behavior that is not ABI-compliant should also be covered by a test for -Wabi to ensure that there is a warning for the construct.
