Table 2.5  Logic Operations Instructions 
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 
Performs a logical exclusive OR operation on a general register and 
another general register or immediate data. 
NOT B/W/L ∼ (Rd) → (Rd) 
Takes the one's complement (logical complement) of general register 
contents. 
Note:  *  Size refers to the operand size. 
 B:  Byte 
    W: Word 
 L:  Longword 
Table 2.6  Shift Instructions 
Instruction Size* Function 
SHAL 
SHAR 
B/W/L Rd (shift) → Rd 
Performs an arithmetic shift on general register contents. 
1-bit or 2-bit shift is possible. 
SHLL 
SHLR 
B/W/L Rd (shift) → Rd 
Performs a logical shift on general register contents. 
1-bit or 2-bit shift is possible. 
ROTL 
ROTR 
B/W/L Rd (rotate) → Rd 
Rotates general register contents. 
1-bit or 2-bit rotation is possible. 
ROTXL 
ROTXR 
B/W/L Rd (rotate) → Rd 
Rotates general register contents through the carry flag. 
1-bit or 2-bit rotation is possible. 
Note:  *  Size refers to the operand size. 
 B:  Byte 
    W: Word 
 L:  Longword
