Question

main.asm

%include "lib.asm"

section .text
global _start

_start:

;
; YOUR CODE HERE!
;

; SAMPLE
mov rdi, 65536 ; going to print 65536
call print_num ; print the number
call print_lf ; move to next line

exit:
mov rax, 60 ; exit
mov rdi, 0 ; return code
syscall

In the main.asm file, you are to create a few arithmetic calculations using the following
instructions:
mov
add
sub
Then after each expression is calculated, you will print the result using:
mov
rdi, XXX
call print_num
call print_lf
The value of XXX will depend on which register your final result landed.
Do this at least 3 times using only the registers ( rax, rbx, rcx and rdx).
For example, if you wanted to print the result of 32 + 5 - 10, you could do something like:
mov
rax, 32
add
rax, 5
sub
rax, 10
mov rdi, rax
call print_num
call print_lf
Remember that in order for the print_num subroutine to print your number, you must move the
result into rdi.
