Error while building JVMCI enabled JDK8 on Power

Hi Doug,
Thanks for helpful response.
I have copied jvmci/jdk.vm.ci.amd64 and jvmci/jdk.vm.ci.hotspot.amd64 to create jvmci/jdk.vm.ci.ppc64 and jvmci/jdk.vm.ci.hotspot.ppc64 (as suggested by Gilles) respectively. I have modified the source code files to reflect ppc64 instead of amd64 in these folders.
Then I realized that graal-jvmci-8/mx.jvmci/suite.py also needs to be updated to incorporate these new folders. I have also added ppc64le as the supported arch for the Distributions in graal-jvmci-8/mx.jvmci/suite.py.
By default, the ppc64 is set as arch for LE versions as well, however this leads to following error. The jdk source code has jvm.cfg file under ppc64le folder:
mx --java-home /usr/lib/jvm/java-8-openjdk-ppc64el build
None
{'ppc64': {'path': 'build/product/linux/ppc64/server/jvm.tar'}, 'amd64': {'path': 'build/product/linux/amd64/server/jvm.tar'}, 'sparcv9': {'path': 'build/product/linux/sparcv9/server/jvm.tar'}}
Creating /home/deepali/Graal/graal-jvmci-8/jdk1.8.0_121/product from /usr/lib/jvm/java-8-openjdk-ppc64el
/home/deepali/Graal/graal-jvmci-8/jdk1.8.0_121/product/jre/lib/ppc64/jvm.cfg does not exist
Thus I think I need to update the arch to ppc64le in the makefiles.
Another thing that I noticed is " WARNING: hsdis with flavor 'None' not supported on this plattform or architecture". So looks like I will need to port hsdis as well because it is not available for ppc at https://lafo.ssw.uni-linz.ac.at/pub/hsdis/.
Regards
Deepali
