I decided to do the fizzbuzz challange using assembly, this is the first thing I decided to do after hello world, there is deffinently room for improvements here

FizzBuzz.asm

section .data
  Fizz db 'Fizz', 10
  FizzLen equ $ - Fizz
  
  Buzz db 'Buzz', 10
  BuzzLen equ $ - Buzz

  FizzBuzz db 'FizzBuzz', 10
  FizzBuzzLen equ $ - FizzBuzz

  Three dq 3
  Five dq 5
  Fifteen dq 15

section .text
  global main
  extern printf

main:
  mov rcx, 20
  mov rax, 0

compare:
  inc rax
  push rax
  push rcx

  mov rdx, 0
  
  idiv qword [Fifteen]
  cmp rdx, 0
  je  Print_FizzBuzz

  pop rcx
  pop rax
  jmp Check_Buzz

Check_Buzz:
  push rax
  push rcx
  
  mov rdx, 0
  
  idiv qword [Five]
  cmp rdx, 0
  je Print_buzz
  
  pop rcx
  pop rax
  
  jmp Check_Fizz
Check_Fizz:
  push rax
  push rcx
  
  mov rdx, 0
  
  idiv qword [Three]
  cmp rdx, 0
  je Print_Fizz
  
  pop rcx
  pop rax
  
  jmp print

  mov rax, 1
  mov rdi, 1

  mov rdx, BuzzLen
