Now, for the second instruction mov $0x1,%ebx, we are initalising the %ebx register with the value 1. Based on the assembly code, you can see that this is being used as a counter/index for the loop.

Here, we can see that the program increments %ebx by 1, adds a 4 byte offset to %rbp (the number we will be matching now), and checks if %ebx is equal to 6. If it is, it breaks the loop and jumps to <phase_2+70> succesfully finishing this stage.

Now, given that we know the first two numbers in the sequence are 0 1, we can calculate the other numbers by following the pattern of adding the counter and the value of the previous number.
