Even without the volatile, it ICEs:
typedef unsigned long int ulong;
typedef struct
{
int counter;
}atomic_t;
static ulong 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));
}
