--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> ---
Makes me wonder if hot/cold splitting should use a special jump instruction
for crossing jumps which we could fixup/split very late so we see

 (parallel
    (set reg (label_ref ..))
    (set pc (reg))
    (clobber reg))

or something like that.  That is, make sure the crossing jump, if
indirect, has the destination computation easily accessible and
replaceable.
