We aren't? We're supposed to be. Before I installed the recent
epilogue changes, I remember adding code to make absolutely sure
we got them.
I just re-checked -- I'm getting them on Alpha:
(jump_insn 65 64 66 (return) -1 (nil)
(nil))
;; End of basic block 0
(barrier 66 65 41)
I can't imagine how ARM would be different for this case.
