Currently it "takes control" and we have a tool similar to what llc
is, except with some small tweaks needed due to the runtime
retargetability etc. There has been plans to make it unnecessary so we
could use llc directly (mainly the generated backends that need to
be loaded as plugin modules), but you know how it is, if it works OK as is,
there're usually some more important things to spend one's time on :)

Yes.
