--- Comment #30 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But at least the zone1_100 stuff is unused in #c26, so improving #c28 there
wouldn't help.
  distbb_99 = distij_98 - radij_82;
  _27 = distbb_99 < 0.0;
  # RANGE [irange] const int [0, 1] NONZERO 0x1
  zone1_100 = (const int) _27;
  if (distbb_99 < 0.0)
_27 is only used by the dead zone1_100.

So, we have 2 different testcases now for 2 different issues.
