Is it possible to suppress the prolog and epilog code emitted by gcc in an
extern function just consisting of asm statements?  E.g in:

extern void foo( void)
{
  __asm__ __volatile ( "...");
}

Even in an optimised (-O3) build the compiler emits:

 pushl %ebp
 movl %esp,%ebp
 ...
 movl %ebp,%esp
 popl %ebp
 ret

TIA
