Are you telling us it's not a secret then?

  Don’t know if this is sarcasm, but no, doubtful it’s a secret. Or might depend on the JVM license. OpenJDK obviously has no secrets. But otherwise, assembly overrides for hot paths in execution targets that support them aren’t actually a big secret, just that they’re rarely visible. Think Go has a lot of processed architecture specific assembly for some functions, especially crypto iirc.

    Yeah, it was a sarcasm. The article (quoted in parent comment) called it a secret implementation.
