UseCodeCacheUnloading question

[Xiaobin Lu]

Hi folks,

I heard Erik from AMD from the JVM language summit about his recent work to
improve Code cache. He mentioned the flag will enable eviction of unused
compiled method from code cache when it becomes full. The flag he mentioned
is -XX:+UseCodeCacheUnloading. But I can't seem to find that flag from
globals.hpp.

Would anyone please shed some light upon this?

Thanks so much!

-Jack
