--- Comment #4 from Roman Zhuykov <zhroma at gcc dot gnu.org> ---
That's great this was finally catched on trunk!
Noticed it probably a year ago, with my modulo-sched changes g++.dg/pr78088.C
compilation runs into that infinite loop. And yes, my local solution was to
organize a "regset visited = ..." to prevent visiting registers again. Now
will continue with applying Jakub's solution.
Although no failing example exist, IMO we should backport this into 8 and 9
brances.
