Code density is one factor in a tremendously complex system. The entire design philosophy of RISC architectures for the last 35+ years is predicated on the notion that it's not the most important one, and shouldn't be focused on in isolation.
- snvzz 4y agoThe RISC paper was all about the need to strongly justify any complexity. I don't quite remember it even touching code density.
