does the 'end' address on a USING statement mean?:
Are dependent USINGs referring to the same base register
allowed to overlap? There should be no objection to this
provided that they resolve to identical base and displacement
regardless which USING is used. But this introduces an
ambiguity in "DROP by address" when that address can be
resolved, albeit equivalently, by either of two dependent
USINGs.
How about allowing the use of an label on the Dependent USING and the
DROP uses that label? That way you and identify the Dependent USING
you are DROPing.
