# Instructions

1. `je <Address>`

This will jump to address if ZF is set to 1, otherwise if ZF(zero flag) is zero it won't make the jump to that address.

2.`jne <address>`

Is exact opp of earlier

3. ```
   SETNE/SETNZ register
   ```

It sets the value of register to 1 if zero flag is 0.

4. `mov rax, rbx`

Move rbx value to rax.

5. `test edi,edi`

does a bitwise AND of the EDI register with itself, and updates the CPU flags based on the result—but it does **not** store any result back into EDI.&#x20;

**ZF (Zero Flag)**:\
Set to 1 if (EDI & EDI) == 0 (i.e. if EDI == 0); cleared to 0 otherwise.
