Hi,
Thanks Thalinger and Volker for quick response.
Do you think that it is possible to build JVMCI for COMPILER2 only instead of building it for both. Please advise.
Regards
Deepali

No, unfortunately not :(
We're currently totally overloaded with Java 9 so we won't have time for JVMCI/Graal until after we've released that.

Looks like I will need all these files for PPC as well. However the corresponding directory - src/cpu/ppc/vm does not have these C1 files, although it does have 2 files for C2. Is there any specific reason due to which C1 implementation is not available for ppc or it is just unimplemented currently. Please advise.

The existing jvmciGlobals_ppc.hpp needs to be renamed to jvmci_globals_ppc.hpp (as you observed) and completed as part of this.
