--- Comment #7 from chenglulu <chenglulu at loongson dot cn> ---
I trimmed the test case and found that the error was caused by the following
statement:

;;   basic block 8, loop depth 1
;;    pred:       7
  if (l_7 == &_rtld_globalD.3739._dl_rtld_mapD.3732)
    goto <bb 9>; [INV]
  else
    goto <bb 10>; [INV]
;;    succ:       9

The following patches can fix the problem, but I don't know the exact reason
yet.
