It comets from the forwprop1 pass:

;; Function floorf (floorf, funcdef_no=15, decl_uid=167, cgraph_uid=107,
symbol_
order=107)

__attribute__((nothrow, leaf, const))
floorf (float x)
{
  double _2;
  double _3;
  float _4;
  float _6;

  <bb 2>:
  _2 = (double) x_1(D);
  _6 = __builtin_floorf (x_1(D));
  _3 = (double) _6;
  _4 = _6;
  return _4;

}

Before that, we have a call to floor.\:

  _2 = (double) x_1(D);
