leu, geu, ltu, and gtu: Two-operand unsigned inequality comparisons.

eq0, ne0, les0, ges0, lts0, and gts0: Single-operand comparisons against zero. As discussed

above, the unsigned comparisons against zero are degenerate.

neq, nne, nles, nges, nlts, ngts, nleu, ngeu, nltu, ngtu, neq0, nne0, nles0, nges0, nlts0,

ngts0: Same as above except that they return negative one for true and zero for false.

naeq, nane, nales, nages, nalts, nagts, naleu, nageu, naltu, nagtu, naeq0, nane0, nales0,

nages0, nalts0, and nagts0: Three-operand functions that compute the logical and of one operand

with the negated result of the comparison ...
