- Subject: Combining SCOPE regions
Hi,
the handling of SEQUENCEs opens quite interesting problem - how do we
want to handle instruction that "belongs" to multiple regions - like
when for instance combine combines instructions from two different
regions. I am thinking about writing fucntion "combined_scope (scope1,
scope2)" that will simply choose the inner one in case they are nested
or return the first one in case it is non-NULL. Is there better way to
do so?
