I think the reason at least for Inline Asm is that Hexagon does not use 
the ScoreboardHazardRecognizer for ScheduleDAGVLIW, therefore this 
backend cannot run into this assertion (and the ScheduleDAG stuff is 
going to be replaced with the MIScheduler anyway in the future, as I 
gathered from the mailinglists (?)).

Kind Regards,
