paizaでアセンブラ

Last updated at Posted at 2018-12-03

概要

思えば、paizaでアセンブラがやりたいだけの一年だった。
paizaでアセンブラ、やってみた。
pythonとgcc使った。 

サンプルコード

import subprocess
import os

def gcc():
    c_file = 'hello.s'
    test_c = """
.code64
.text
.globl main

main:
    mov   $1, %rax; 
    mov   $1, %rdi; 
    mov   $msg, %rsi; 
    mov   $12, %rdx; 
    syscall;
    mov   $0, %rax; 
    syscall;

.data
msg:
    .asciz "Hello world!"
"""
    with open(c_file, 'w') as f:
        f.write(test_c)
    os.system("gcc -no-pie %s" % c_file)
    result = subprocess.Popen('./a.out', stdout = subprocess.PIPE).communicate()[0]
    for i, v in enumerate(result[ : -1].split('\n')):
        print v

if __name__ == '__main__':
  gcc()


成果物

以上。
