XOR.LT
Less Than Accumulating
XOR.LT.U
Less Than Accumulating Unsigned
Description
Calculate the logical XOR of D[c][0] and the Boolean result of the LT or LT.U operation on the contents of data
register D[a] and either data register D[b] (instruction format RR) or const9 (instruction format RC). Put the result
in D[c][0]. All other bits in D[c] are unchanged. D[a] and D[b] are treated as 32-bit signed (XOR.LT) or unsigned
(XOR.LT.U) integers. The value const9 is sign-extended (XOR.LT) or zero-extended (XOR.LT.U).
XOR.LTD[c], D[a], const9 (RC)
D[c] = {D[c][31:1], D[c][0] XOR (D[a] < sign_ext(const9))};
XOR.LTD[c], D[a], D[b] (RR)
D[c] = {D[c][31:1], D[c][0] XOR (D[a] < D[b])};
XOR.LT.UD[c], D[a], const9 (RC)
D[c] = {D[c][31:1], D[c][0] XOR (D[a] < zero_ext(const9))}; // unsigned
XOR.LT.UD[c], D[a], D[b] (RR)
D[c] = {D[c][31:1], D[c][0] XOR (D[a] < D[b])}; // unsigned
