Thanks for the quick feedback! I understand the GCC 13 branch is currently frozen for the upcoming final release. Since this patch series is purely an ISA/target enablement backport for Arrow Lake (with no changes to standard generic x86 pipelines) and has passed all 24,000+ DejaGNU tests without regression, I would appreciate it if the Release Managers could consider it for an exception.
If an exception isn't possible at this stage, please let me know if it would be suitable to land right after the release tag is created.
