Here is an XCore patch to lower FRAME_TO_ARGS_OFFSET:

    XCore target: Lower FRAME_TO_ARGS_OFFSET

    This requires a knowledge of the stack size which is not known until
    the frame is complete, hence the need for the XCoreFTAOElim pass
    which lowers the XCoreISD::FRAME_TO_ARGS_OFFSET instrution into its
    final form.
