Hello,
We found -fsigned-char is added to ppc platform, but not added to ppc64 platform. As they are different platforms, I think it is needed for ppc64 as well. Currently I just added one line modification as follow, but there may be more places to modify. If some one can give some comments, I can make a complete webrev.
The buggy scenario we found needs closed code to reproduce, so it is not reproduced with current openjdk build on ppc linux from AIX porting project. I tested with ibmjdk, the patch works.
I found CFLAGS_REQUIRED_ppc is from changeset http://hg.openjdk.java.net/jdk8/jdk8/jdk/rev/54d8193f177b . Is it enough to add ppc64 option for places ppc appears in that patch?

You should probably bring this to build-dev to discuss. If the linux-ppc64 port is a jdk8 port then you should probably be looking at the new build and we should be cutting over soon. -Alan
