This looks good. Small note: I don't see skip_Replay variable usage in other
places.
Yumin, could you add replay to C1 compilations as next step?
Thanks,
Vladimir

Hi,
Please give your comments of the changes about
6830717: replay of compilations would help with debugging.

Sometime jvm crashes in the process of compilation or in compiled
method. To reproduce the compilation process in debug JVM is helpful for
quickly identifying root cause.
To do recompilation, we collect data by using of SA (Serviceability
Agent) to extract application and system class data from core file.
Those information includes nmethod, methodOop, methodDataOop,
instanceKlass and corresponding ci counterparts.
With reconfiguring similar (not exactly same) compiling environment as
in the core file, try to compile again the failed java methods.
