Question

I have a simple assembly code file called exit.s that looks like the following:

.text
.globl _start
_start:
        xor %eax, %eax
        mov %al, 1
        xor %ebx, %ebx

I would like to get the hex byte code of this. How would I do this on a linux machine? What commands would I use?

Answer 1

Use gcc to compile it into an executable, then use objdump -d to print out the code:

gcc -c -o my_file.o my_file.s
objdump -d my_file.o
