[Bug tree-optimization/70586] [4.9/5/6 Regression] wrong code at -O2 and -O3 on x86_64-linux-gnu in 32-bit and 64-bit modes


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70586

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
int a, e, f;
short b, c, d;

int
foo (int x, int y)
{
  return (y == 0 || (x && y == 1)) ? x : x % y;
}

static short
bar (void)
{
  int i = foo (c, f);
  f = foo (d, 2);
  int g = foo (b, c);
  int h = foo (g > 0, c);
  c = (3 >= h ^ 7) <= foo (i, c);
  if (foo (e, 1))
    return a;
  return 0;
}

int
main ()
{
  bar ();
  return 0;
}

I think this goes wrong during ifcombine, will have a look tomorrow.
