Error while building JVMCI enabled JDK8 on Power

[Deepali Patel]

Thanks Doug and Gilles for quick response. 

Could you please throw some more light on the parts of code(folders, files etc) that will need to be updated/modified to get this working on PPC. Would we need assembly code as well? If so, could you please point me to the corresponding x86 files for reference. 

Regards
Deepali

You will also need to implement the Java side of things.
See for example the sources in jvmci/jdk.vm.ci.amd64 and jvmci/jdk.vm.ci.hotspot.amd64.
