           Summary: Compilation failure, ambiguous fisttp
           Product: gcc
           Version: 13.0

          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: simon at pushface dot org
  Target Milestone: ---
