> `-XX:+SuperWordRTDepCheck` is a develop flag and misses proper implementation. But when enabled, it could change code path, resulting in the failures in [JDK-8291781](https://bugs.openjdk.org/browse/JDK-8291781) and [JDK-8291881](https://bugs.openjdk.org/browse/JDK-8291881). As @vnkozlov suggested in [JDK-8291781](https://bugs.openjdk.org/browse/JDK-8291781), the small patch converts the flag to pure debug code to avoid effect on code generation.
