Just noting, even if instructions were 100000000000000 bits long, reserving a single bit for 16-bit encoding would waste 50% of the instruction space.

- brucehoult 2mo agoIt's not wasted when it makes programs overall smaller, as it does.
- chrisjj 2mo agoIt is wasted if its reduction is less than that of alternative uses for that instruction space.
- brucehoult 2mo agoSuch as? There is still plenty of unused 32 bit (30 bit) opcode space.
