A small testcase:

[hjl@gnu-6 pr53249]$ cat x.i
struct gomp_task
{
  struct gomp_task *parent;
};

struct gomp_thread
{
  int foo1;
  struct gomp_task *task;
};

extern __thread struct gomp_thread gomp_tls_data;

void
__attribute__ ((noinline))
gomp_end_task (void)
{
  struct gomp_thread *thr = &gomp_tls_data;
  struct gomp_task *task = thr->task;

  thr->task = task->parent;
}
