$ gcc -S buffer-overflow.c && cat buffer-overflow.s
_foo:
pushl %ebp ;2
movl %esp, %ebp ;3
subl $16, %esp ;4
movl LC1, %eax ;5
movl %eax, -4(%ebp) ;6
leal -4(%ebp), %eax ;7
leal 8(%eax), %edx ;8
movl $_bad, %eax ;9
movl %eax, (%edx) ;10
leave
ret
_main:
...
call _foo ;1

The help information says it should not compile nor assemble:
-S Compile only; do not assemble or link
Why are they contradictory?
