Since the stack could be any arbitrary place in memory, I'm afraid you 
don't got too many choice but set-up the content by yourself.

When a local array of char is declared in C, i.e. something like:
void foo()
{
   char s[] = "hello world";
}
The compiler does just the same thing as you by MOVL, and when the 
string is rather long, the compiler would place the string in .data and 
call memcpy() to copy it to stack.
