Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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: Internal compiler error generated from presumably valid code.

Cross-compiling drivers/net/ethernet/8390/ne-h8300.c for H8300 architecture provided the following:

Comment 5 Jakub Jelinek 2013-10-22 17:30:44 UTC 
The h8300 compiler isn't shipped (and thus not supported) in any RHEL.
Perhaps you want to file this against Fedora cross-gcc and CC GES people, or file it upstream?
Comment 6 DJ Delorie 2013-10-22 18:19:17 UTC 
FYI I've reproduced this with upstream gcc version 4.9.0 20131016.
Comment 7 RHEL Program Management 2013-10-25 18:35:37 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 8 Jeff Law 2014-02-04 18:57:39 UTC 
Per c#5.  

Matthew, if you want this fixed, you really need to take it upstream as we haven't and probably never will support the H8/300 compilers.
