Testcase that still FAILs on the trunk:

/* PR target/94368 */
/* { dg-do compile { target fpic } } */
/* { dg-options "-fpic -O1 -fcommon" } */

int b, c, d, e, f, h;
short g;
int foo (int) __attribute__ ((__const__));

void
bar (void)
{
  while (1)
{
  while (1)
{
  __atomic_load_n (, 0);
  if (foo (2))
__sync_val_compare_and_swap (, 0, f);
  b = 1;
  if (h == e)
break;
}
  __sync_val_compare_and_swap (, -1, f);
}
}

Actually, I can, -O2 -fpie is needed.
Started with r9-3744-gd400fda3a8c3330f77eb9d51874f5482d3819a9f
