class XMMPainter
{
  float call()
  {
    return sumFloats(0.0f, 0.0f);
  }

  static float sumFloats(float a, float b)
  {
    return a + b;
  }
}

void testXMM()
{
  auto painter = new XMMPainter;
  assert(XMMPainter.sumFloats(20, painter.call()) == 20.0f);
}

---

The expression painter.call() is evaluated after 20 has been loaded into xmm1,
but the register is not saved.
