3. What is your memory like? Is it byte-addressed? Then on a 64-bit machine, 7/8ths of your addresses mapped to GPRs are between registers. What do you do with those? Do you allow these unaligned reads? Good luck register-renaming that. You have to, at the very least, check for
So I'm just looking for a more in depth understanding of whether it's really the right idea to have n "phantom" addresses that don't actually map to anything as the core way that instruction streams are written...

... instead of some other potential scheme that still reflects the fact that these are special, just not necessarily "phantom".
