In the flight controls architecture diagram in the QRH, it shows that by losing ELAC 1 and green hydraulics, you will lose the left aileron and both outermost roll spoilers, but all other roll controls will still be operational - i.e. three roll spoilers per wing and the right aileron
Additionally from the FCOM, DSC-27-10-20 Architecture/Roll control: if either an ELAC or a hydraulic service fails, the relevant aileron servojack will automatically go into damping mode, where it follows the control surface but damps its movement.
