I am trying to think of any benefit 64bit powerpc has over 32bit other
than the memory space for the process and I don't know if there is any.
After all the architecture was designed from the begining with both 32
and 64 bit in mind and hence I suspect they were meant to be as similar
as possible in terms of register count and such. So I suspect you gain
an increase the the process size along with the doubling of pointer size
which is usually considered a disadvantage of course (although how much
that matters depends on the application of course).
