[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2006-07-30 14:44 -------
Confirmed (reduced C and C++ testcases:
typedef unsigned long int ulong;
typedef struct
{
  volatile int counter;
}atomic_t;
static ulong volatile Cversion = 0;
void
sp_cache_invalidate ()
{
  atomic_t * v1 = (atomic_t *)& Cversion;
  atomic_t * v = v1;
  __asm__ __volatile__ ("lock ; incl %0":"=m" (v->counter):"m" (v->counter));
}
