            Bug ID: 121041
           Summary: Missed tail calls for sjlj targets with empty
                    exception handling code
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: amylaar at gcc dot gnu.org
  Target Milestone: ---

testsuite/g++.dg/opt/musttail3.C and testsuite/g++.dg/opt/musttail5.C fail for
sjlj targets; the tail call optimization is rejected becasue the check for
empty exception handling code is not effective for the sjlj handling.
