The Power 9 regression tests match the expected results. The Power 8 regression tests have improved with none/tests/fdleak_ipv4 (stderr) no longer failing. Other then that the results are the same. The Power 7 regression tests are as expected. The valgrind 3.16.0.RC1 looks good on Power. Carl Love |
