The retire() operation is brilliant!
To me, it shows the hallmark of a great invention — that it seems “simple” — but only after I fully absorbed the flash of insight.
To quasi-quote President Carter, I lust in my heart for this CPU architecture!
Not just because it’ll be fast, but because it’s fast yet clean.
(I suppose it’s irrational, but even when I don’t have to look at the assembly code, I’d much rather work on a clean machine than on something I consider ugly.)
