Instruction Size* Function
AND B/W/L Rd ∧ Rs → Rd, Rd ∧ #IMM → Rd
Performs a logical AND operation on a general register and another
general register or immediate data.
OR B/W/L Rd ∨ Rs → Rd, Rd ∨ #IMM → Rd
Performs a logical OR operation on a general register and another
general register or immediate data.
XOR B/W/L Rd ⊕ Rs → Rd, Rd ⊕ #IMM → Rd
