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 of problem:

Re "and ia64 kernels" -- since 6.0 we don't care of IA64.

Re "x86_64": I remember doc folks use somewhat suitable names for those archs (something like "Intel ET 64..."). But perhaps we don't care in devel docs that much?

Also to this paragraph: For the sake of completeness, IBM seems to support S/390 compilers (and likely POWER architecture too).

Re "Do we support Ada and Objective-C in RHEL?": There weren't much Ada bugs in the past, however we have Ada as well as ObjectiveC in main repo (i.e. not the optional one); see http://download.englab.brq.redhat.com/pub/rhel/nightly/latest-RHEL-6/6.0/Server/i386/os/Packages/.

Re "insruction length": Typo.

Re "Intel ATOM": Should be "Intel Atom".

Re "Power 7" -> "POWER7".

+ Another feature in GCC which is post upstream 4.4: See bug 538266: https://bugzilla.redhat.com/show_bug.cgi?id=538266#c4

Re compatibility with gcc-3.4: We had 4.1 in FC 6 at least, 3.4 could be there as package compat-gcc34 only, so it wasn't it's primary compiler.

Re buggy gcc-4.2.1: I guees we never shipped it in RHEL, so we should not care?

Re elfutils and "what happens if i compile without it?" A: Pretty much nothing bad. elfutils are good for object files and executables introspection, not for compilation and linking.

Paragraph starting "Compiling with GNU GCC tools..." is there twice.
