--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Also, the PR has nothing to do with OpenMP:
-O2 --param max-rtl-if-conversion-unpredictable-cost=3D0 on x86_64-linux IC=
Es
too:
typedef long long int V __attribute__((vector_size (16)));

long long int
foo (V x, V y)
{
  long long int t1 =3D y[0];
  long long int t2 =3D x[0];
  long long int t3;
  if (t2 < 0)
    t3 =3D t1;
  else
    t3 =3D 0;
  return t3;
}
And that started with r8-3977-gef9eec0b599d533b58e29fe0c0bf6435e5368378 (la=
tent
before because of different costs).=
