            Bug ID: 81206
           Summary: missed tail recursion
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

We do not handle the tail-recursion in gcc.dg/torture/pr81203.c because there's
a stmt in the way (see PR81203).  A proper fix is to re-do tail-recursion
elimination isolating the individual paths to the return I think.
