--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- jump2 (which is after RA) does this for aarch64: Forwarding edge 2->3 to 5 failed. verify found no changes in insn with uid = 11. Edge 2->4 redirected to 5 scanning new insn with uid = 47. Replacing insn 11 by jump 47 deleting insn with uid = 11. deleting insn with uid = 38. deleting block 3 deleting block 4 Removing jump 47. deleting insn with uid = 47. Merging block 5 into block 2... changing bb of uid 43 changing bb of uid 44 from 5 to 2 changing bb of uid 45 from 5 to 2 Merged blocks 2 and 5. Merged 2 and 5 without moving. For x86_64 does not have this.
