if ((unsigned) rA < (unsigned) (0x0000 : IMM16))
then rB ← 1
else rB ← 0
cmpltui rB, rA, IMM16
cmpltui r6, r7, 100
Zero-extends the 16-bit immediate value IMM16 to 32 bits and compares it to the value of rA. If
rA < (0x0000 : IMM16), then cmpltui stores 1 to rB; otherwise stores 0 to rB.
cmpltui performs the unsigned < operation of the C programming language.
