           Summary: gfortran.dg/bessel_7.f90 failures on
                    s390-ibm-linux-gnu
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org
              Host: s390-ibm-linux-gnu
            Target: s390-ibm-linux-gnu


On s390-ibm-linux-gnu the infamous bessel_7 test fails. One probably needs to
update the epsilons a bit - but I have not really though about the correct
values - hence this bugreport.

The only failing test is:

[...]
 YN for X =    34.529999      -- Epsilon =   1.19209290E-07
[...]
26 -0.174342096E-01 -0.174342729E-01    0.63E-07-30.4717006683  T  F

Thanks to Andreas Krebbel for running the test.

Mark as regression to keep in on my radar. The test case is new thus one can
argue whether it is a regression or not.

Fixed - hopefully.

The PR can be closed if a "4.6.0 (experimental)" build for s390 does no longer
has a failing bessel_7.f90.

FIXED: http://gcc.gnu.org/ml/gcc-testresults/2010-11/msg01211.html

Failing is only gfortran.dg/allocatable_scalar_5.f90, which is PR 46485.
