That would be a more fundamental behavior change which at least should 
be added as a reference to the annotation below. Seems for ppc64el and 
s390x this was changed in the past but I am not sure whether this might 
break assumptions or use cases on the x86 side.
Adding a few more cc's for discussion/awareness.
