            Bug ID: 113005
           Summary: 'libgomp.fortran/rwlock_1.f90',
                    'libgomp.fortran/rwlock_3.f90' execution test timeouts
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: testsuite-fail
          Severity: normal
          Priority: P3
         Component: libfortran
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
            Target: powerpc64le-linux-gnu

On several of our "big iron" powerpc64le-linux-gnu systems, I'm seeing the new
test cases 'libgomp.fortran/rwlock_1.f90', 'libgomp.fortran/rwlock_3.f90' run
into execution test timeouts (300 s).  Those were added in commit
r14-6425-gb806c88fab3f9c6833563f9a44b608dd5dd14de9 "libgfortran: Replace mutex
with rwlock".
