Yes, within a loop we get the expected addressing.  Updated testcase:

/* -Os -mcpu=405 -msoft-float */
struct x
{
  int a[16];
  int b[16];
  int c[16];
};

extern void foo (int, int, int);

void
f (struct x *p, unsigned int n)
{
  foo (p->a[n], p->c[n], p->b[n]);
}

void
g (struct x *p, unsigned int n)
{
  int i;

  for (i = 0; i < n; i++)
    foo (p->a[i], p->c[i], p->b[i]);
}
