compile error on mac ppc box

Wed Apr 3 00:41:36 PDT 2013

Hi,

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).

Regards,
Volker
