Project Proposal: PowerPC/AIX port

Hi Henri,

we have limited resources and as outlined in the proposal, we will focus on
Linux/PowerPC64 and AIX. In  particular, the PowerPC port of HotSpot
will be 64-bit
only simply because this is what we currently have.

However this is an Open Source project and anybody willing to
contribute may join the project.

I think one particularly good point in time to join the project would
be when we have
the interpreter-only version of HotSpot running on Linux/PPC64. I
suppose it should be
not to hard for an OS/X expert to merge the processor specific part
with the OS/X
OS part from the current Mac OS X port.

By the way, does OS/X only support 32-bit or both 32- and 64-bit?
