Minimal example to compile & run assembly with gcc?

int main(int argc, char* argv[])
{
  return 0;
}

what's the shortest assembly example to do the same that can be compiled into an executable by gcc?

I came across this ex开发者_Go百科ample but there're too many tags like hi_temp:,.data etc,what's the minimal version?

.text
    .align 4
    .globl main
main:
     pushl %ebp
     movl %esp,%ebp
     xorl %eax,%eax
     leave
     ret

To compile and run:

$ gcc -m32 asm.S
$ ./a.out

.text
    .globl main
main:
     xorl %eax,%eax ;return 0
     ret

Here's an example of Hello World in assembly, along with an explanation:
