> once newer iterations of X86-64 drop support for legacy instructions (...) - we will have smaller, more efficient X86-64 chips. Don't get too excited about it. The old compatibility is going to be tiny in the die space compared to even basic Intel extensions. And it's not just the old code - new code may well contain a "mov al..." so you can't just drop it. All of those instructions will stay with us for decades. |
