------- Comment #36 from rguenth at gcc dot gnu dot org  2008-02-10 22:36 -------
Actually the wrong types are caused by loop IM which replaces the bittest

  D.1210_17 = D.1208_13 >> 63;
  D.1211_2 = (int) D.1210_17;
  if (D.1211_1 != 0)

by

  shifttmp.48_12 = 0x8000000000000000;
  shifttmp.48_16 = shifttmp.48_12 & D.1208_13;
  if (shifttmp.48_16 != 0)

but forgets to update the type of the zero.  Testing the patch.
