Segfault with x86 assembly -

i'm trying assemble small piece of x86 code. i'm on 32 bit machine , have written following code. should add values eax , return. realize there not output. when compile using

gcc main.s -o main

it compiles no errors. when run seg faults (gdb claims segfaults on first movl instruction). main.s has following code in it. doing wrong?

.text   .globl main   main:   pushl    %ebp   movl     %esp, %ebp   movl 0,  %eax   addl $3, %eax   addl $3, %eax   leave  ret 

not first, second movl

movl  0,%eax 

isn't using literal $0 address 0. produce segfault!
