            Bug ID: 114482
           Summary: remove_unreachable_eh_regions could use a work queue
                    instead of being recusive
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: internal-improvement
          Severity: enhancement
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Noticed while looking PR 114480, remove_unreachable_eh_regions uses
remove_unreachable_eh_regions_worker which does a huge recusive work but maybe
we should remove this recusiveness behavior, especially if the number of
regions is huge.
