Re: 64 bit addressing

You should take a look at the white papers on Apple's website dealing with the G5 processor and the PowerMac architecture. I think your questions will be answered there.

I haven't seen this asked yet nor did I find it in the archives, so sorry if it's been covered.

Now that the G5 has 64-bit addressing, how do you build your code to use 64-bit pointers with GCC3.3 (so that 'struct foo * bar' is an 8 byte pointer)?

If you already have a 32-bit addressed binary, how will the G5 deal with it and what penalties/problems will be encountered vs. 64-bit?

How does this all apply to KEXTs; are they required to be 64-bit or is 32-bit ok?
