Legend
- In the "Opcode" column:
/digitmeans that the opcode has 3 extra bits stored in the REG field of the ModR/M byte. ex:F6 /3meansNEG r/m8./rmeans that the instruction's register operand is stored in the REG field of ModR/M. - In the "x" column,
Lmeans the instruction can use aLOCKprefix.smeans that an additionalpush.pmeans an additionalpop. P means twopop's. - In the operands columns, operands with
!are implicit, operands with*are modified. - In the "Flags" column, only the flags affected are represented (in the set
odiszapc). - The column "Ref." points to the corresponding chapter & page in Intel's manual reference vol. 2. (or in the HTML version here
Operand types
rel8(8 bits, signed. Represents a relative address from -128 to +127).rel16,rel32(16 / 32-bit, signed. Represents a relative address from –32,768 to +32,767 / –2,147,483,648 to +2,147,483,647 according to the operand size).imm8(8-bit, signed, Represents an immediate value. It is sign-extended to form a 16 or 32-bit immediate if it's combined with a 16 or 32-bit operand).imm16,imm32(16 / 32-bit, signed. Immediate value).r/m8(8-bit register or a byte from memory).r/m16,r/m32(16 / 32-bit register or value in memory, according to the operand size).m,m8,m16,m32,m64,m128(an operand in memory, expressed as a variable or array name, but pointed to by the DS:(E)SI or ES:(E)DI registers).m16int,m32int,m64int(integer operand in memory).ST(i)(the i'th element from the top of the FPU register stack (0 to 7), 0 by default).
