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 Paulo Andrade 2017-01-20 19:14:56 UTC 
Created attachment 1242970 [details]
gcc48-sfdc01776144.patch

While switching from rhel 6.7 to rhel 7.2, user noticed a very
high increase in compile time (from 32 seconds to 26 minutes).
 
  User tested attached patch, that is missing in rhel 7.2 gcc,
as fix to upstream PR middle-end/60291.

  The patch was rediffed from
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=208113
because the fuzz in the change:
248: static bool
249: mem_attrs_eq_p (const struct mem_attrs *p, const struct mem_attrs *q)

to

248: bool
249: mem_attrs_eq_p (const struct mem_attrs *p, const struct mem_attrs *q)

  User reports a gcc build with this patch corrects the problem.
