The WHILE instructions generate a predicate that is true while the comparison of the first scalar operand (incremented for each predicate element) with the second scalar operand is true and false thereafter. WHILELE While incrementing signed scalar less than or equal to scalar WHILELO While incrementing unsigned scalar lower than scalar WHILELS While incrementing unsigned scalar lower than or same as scalar WHILELT While incrementing signed scalar less than scalar e.g. whilele p0.s, x0, x1 generates predicate p0 (for 32bit elements) by incrementing (signed) x0 and comparing that vector to splat(x1). llvm-svn: 338211
