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.

Sourceware 26406 0 P2 RESOLVED Extreme assembling time regression with 2.35 and master 2021-06-24 13:24:11 UTC

Description Josh Coopman 2021-06-24 13:24:12 UTC
Description of problem:
Customer is seeing some large performance differences when compiling/assembling certain code from toolset6 vs. toolset10.  The code assembles in around 25 seconds on toolset6 and about 29 minutes on toolset10.  They did some research and found a bugfix that they thought applied:

https://sourceware.org/bugzilla/show_bug.cgi?id=26406

They compiled in the fix and showed an improvement down to 23 seconds with the binutils they patched from toolset10.  They'd like this put in an updated binutils package.


Version-Release number of selected component (if applicable):
RHEL 8.3 

How reproducible:
Always

Steps to Reproduce:
1. (in linked sourceware BZ)
