What if Knuth's MMIX instructions MOR and MXOR were available? http://mmix.cs.hm.edu/doc/instructions-en.html#MOR What if we also had similar operations on entire bytes ("BMOR" and "BMXOR")? Just a small matter of wires and gates (and doubtless << IEEE 754 support). We accept quaint instruction sets much as we do the quaint rules of chess. But needn't always, and, I hope, shan't someday.
