I initially had this machine attribute but, when I remember correctly, but wasn't able to
communicate it down into the target code. But anyhow, the "mode" is eventually obsolete in light
of the temporarily constructed accelerators.. I will further comment on this as reply to your
comment on the cover letter to keep it in place.
