    : DelayedMasm(owner, masm, root) {
    // We use the root register as an extra scratch register.
    // The root register has two advantages:
    //  - It is not in crankshaft allocatable registers list, so it can't
    //    interfere with the allocatable registers.
    //  - We don't need to push it on the stack, as we can reload it with its
    //    value once we have finish.
