            Bug ID: 69528
           Summary: s/s390: ext/special_functions/hyperg lots of failures
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vogt at linux dot vnet.ibm.com
                CC: krebbel at gcc dot gnu.org
  Target Milestone: ---
            Target: s390x

The hyperg functions fails to stay inside the tolerance allowed by the new
test.  Either the function's precision is not good enough on s390x, or the
allowed tolerance is too small (or both).
