It will take a fair amount of time to try to figure out what the underlying dataflow problem is and then figure out how to modify it so that it is strictly monotonic (i.e. guaranteed to converge). However, given that this is just improving debugging information, it should be possible to just hack a count of the number of iterations and just stop after 20, i.e the way that flow used to do it. If this is a blocker, this is what I would do to get the release out of the door. Kenny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35065
