--- Comment #23 from Jorn Wolfgang Rennecke <amylaar at gcc dot gnu.org> ---
I see this test PASS for 16 bit esirisc and FAIL for 32 bit esirisc.
foo is last seen in pr108357.c.141t.dce3,

  if (_8 != 0)
    goto <bb 4>; [67.00%]
  else
    goto <bb 3>; [33.00%]

  <bb 3> [local count: 598933191]:
  foo ();

  <bb 4> [local count: 1073741826]:
  return 0;

and is disappeared from
pr108357.c.142t.forwprop3
