I'll grant you immediate moves, but not addressing modes. It lacks the auto-increment/update possibilities that were in the pdp-11, vax, mc68k, and power(pc),

I'll grant you immediate moves, but not addressing modes. It lacks the auto-increment/update possibilities that were in the pdp-11, vax, mc68k, and power(pc), and are great for cutting down on instruction counts in loops. (Hell, on the CDC6600, address register updates were the only way you could do loads and stores; many good ideas didn't survive into the impoverished x86 era.)
