Why do you even talk about ARM64? We have no idea how
well it will work, and how good/bad it will be. It looks
like a largely traditional RISC architecture, and we know
just how well those worked.
For all we know, it will have the same problems with
huge I$ footprints etc. There's nothing special about it,
and it throws out everything ARM learnt from Thumb2.
Sure, it may be easy to decode, but so was alpha. Nobody
cares. That's not where the problems spots tend to be.
