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.

Description Jakub Jelinek 2014-05-20 15:10:36 UTC

+++ This bug was initially created as a clone of Bug #1099547 +++

GCC 4.9 to be included in DTS 3.0 has OpenMP 4.0 support.
For DTS we are using libstdc++_nonshared.a (similarly for libgfortran) + system shared libraries, but for libgomp that is not possible, on the other side the backport isn't large and has minimal risks on OpenMP 3.1 and earlier programs compiled by GCC 4.8 and earlier.

A test build of the backport has been performed (scratch on RHEL 6.x).

For testing, make check in libgomp (performed during gcc build) and make check in DTS 3.0 gcc libgomp (with the GCC 4.9.* built libgomp.so.* replaced with the updated system one) is needed.

Comment 1 Jakub Jelinek 2014-05-20 15:22:07 UTC

Note, in RHEL 6, a similar thing has been done already in March 2012 (backport of OpenMP 3.1 support).
