--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
These warnings were fixed by richi's r13-6905 for Bug 107087:

  tree-optimization/107087 - missed CCP after forwprop

  When forwprop simplifies the CFG the 2nd order opportunities by
  exposed degenerate PHIs are not realized.  The following improves
  this by properly tracking executable edges and thus handling this
  for non-cyclic CFGs at least.

  This avoids the bogus diagnostic reported for the testcase in this PR.
