NEG - Two's Complement Negation. Usage: NEG dest. Modifies Flags: AF CF OF PF SF ZF. Subtracts the destination from 0 and saves the 2s complement of "dest" back into "dest".
If you want to know what instructions do, consult the reference manuals. The essential reference, namely the Intel instruction set manual says this about the NEG instruction: Flags Affected The CF flag set to 0 if the source operand is 0; otherwise it is set to 1. The OF, SF, ZF, AF, and PF flags are set

neg (Negate) instruction. Purpose. Changes the arithmetic sign of the contents of a general-purpose register and places the result in another general-purpose register. Syntax
The NEG instruction negates a value by finding 2's complement of its single operand. This simply means multiply operand by -1. When a positive value is negated the result is negative. A negative value will become positive. Zero remains zero. For example, mov al, -1 ; Load register neg al ; AL now has 1
Description. Replaces the value of operand (the destination operand) with its two's complement. (This operation is equivalent to subtracting the operand from 0.) The destination operand is located in a general-purpose register or a memory location. This instruction can be used with a LOCK prefix to allow the instruction to

15 Feb 2016 Description. Replaces the value of operand (the destination operand) with its two's complement. (This operation is equivalent to subtracting the operand from 0.) reg = 0 - reg. Actually, a. neg. instruction is the result of a. not. and. add 1. as shown below: 00000101 5 11111010 not(5) 11111011 not(5)+1 = -5
NEG pseudo-instruction Negate the value in a register. Syntax NEG{cond} Rd, Rm where:cond is an optional condition code. Rd is the destination register. Rm is the register containing the value that is subtracted from zero. Usage The NEG pseudo-instruction negates the value in one register and.
