RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 3 Nick Clifton 2016-03-01 14:25:54 UTC 
Hi Miloš,

  The GAS failure is due to the patch that suppresses TLBIE instruction checking.  (I forgot to check that the GAS testsuite did not test the instruction, and of course it does).  I will upload a simple patch that will
fix that problem.

  The LD failures however are a mystery.  I cannot reproduce them.  I assume
therefore that they must be an artefact of running the tests natively.  I
could create a patch to just mark those tests as expected failures, but I
would prefer to get to the bottom of the problem.  (I suspect that I just need
to add a line to regexp files to skip dumps of the .data section).  Is there a
RHEL 7.3 PPC64 machine available that I can use for testing ?

Cheers
  Nick

Fix PowerPC linker tests

With access to a PP64 machine (thanks Milos), I was able to reproduce the 
failures and find the cause - the native ppc tools always create a .data section
even if one is not needed.  This patch tweaks the failing linker tests to allow
for this fact.

Once we have a QA ACK, the two patches should go in.
