compile error on mac ppc box

Using the AIX-Linux-PPC project I've started to add BSD/Mac/PPC support in. I've been able to identify PPC boxes and in particular the 64 bit cpu (ppc970) and have gotten to the point where the build makes it into the hotspot project. Looking at the AIX hotspot code it appears that things are coded for the xlc compiler tool set whereas the Linux/PPC code appears to be coded for the gcc tool set. The last version of tools from Apple for PPC (Mac OS 10.5.8 and XCode 3.1.4) included the gcc and LLVM tool sets. Based on this I'm going to guess that I should use the Linux/PPC code (hotspot/src/os_cpu/linux_ppc/vm) as the starting point for BSD/PPC support and not the AIX code? Searching around on the web I did find references to xlc tools for Mac OS but it doesn't appear to be available and I'm not sure if that would be the best way to go since it wasn't part of the Apple provided tools.

I just want to mention that the current ppc-aix code is 64-bit only. Unfortunately I'm not familiar at all with Mac/PPC and I don't know if it supports 64-bit PPC binaries. If it does I think it should be possible to combine our port with the bits from the MacOS port to get C2-JIT support on Mac/PPC. If not it would be a considerable effort to implement 32-bit PPC support for the ppc-aix port and we don't plan to do that.
We've just lifted the JDK7 version of the ppc-aix port to hsx24 (with the new JSR292 implementation) and it builds and runs fairly well on Linux and AIX (if not please let me know:).
For the next month will now concentrate on JDK8 (we already have a running hsx25 for PPC64 but still have to do all the other class-library, build, etc.. stuff).

Kurt & others,
Thanks for your time and feedback. I'll take a look at the ppc-aix code and see what I can do to get started.

Based on the information provided so far, if I were to start working
on ppc for OS X now, I'd start with ppc-aix-port. Zero while functional,
was extreemly slow. Native support would be best.
Looking at this tree:
I see that it is following jdk7u and has tags for jdk7u14 so it has
MacOS x86 support that was merged in around 7u6.
The hardest part of the work will be in taking the code here:
and porting it to
