After enjoying coding on 680x0 in my youth and later being frustrated by x86, I acclaim that new ISA. There is a design decision I'm curious about but I could not find related information. How did they come with the names "x0, x1, x2..." for general purpose registers, instead of the more conventional "r0, r1, r2..."?
- _chris_ 9y agox for "fixed point". r for "register" is too vague.
