33rd Degree Conference
Kraków, 7 April, 2011
Matthias Hryniszak
The following presentation is intended for informational
purposes only.
There’s no part of it that you should consider either a
guideline, viable option or production-ready set of
instructions that could solve your problem
If you use any concepts of what you see here it is
entirely up to you to make sure it works for you.
The story
so far…
X86 asm
section .text
global _start
;must be declared for linker (ld)
_start:
;tell linker entry point
mov edx,len ;message length
mov ecx,msg ;message to write
mov ebx,1
;file descriptor (stdout)
mov eax,4
;system call number (sys_write)
int 0x80 ;call kernel
mov eax,1
;system call number (sys_exit)
int 0x80 ;call kernel
section .data
msg db 'Hello, world!',0xa ;our dear string
len equ $ - msg
;length of our dear string
C/C++
#include <stdio.h>
#include <stdlib.h>
int main() {
println("Hello, world!");
}
#include <iostream>
