Great thank you! The change should only have minimal impact on code generated on a thunderx2t99, the worst thing that could happen is that arithmetic instructions that have been fused with BCC during instruction scheduling would now be scheduled back-to-back in the PostRA MachineScheduler too, whereas before they might not have been, because the constraints weren't added for the PostRA MachineScheduler.
