Comment (by bgamari):

 Replying to [comment:30 altaic]:
 > I pointed out two shortcomings of the current semantics already. Even
 with the proposed symbol offsets, the prefix data must start with a
 target-dependent frontend-constructed instruction, which is subsequently
 not used. I.e. it requires carefully constructed garbage bytes. To me,
 that sounds kind of... not good.

 I could be mistaken but I don't believe this should be necessary with
 symbol offsets as the inliner won't see the info table at all (since the
 symbol points to the entrypoint of the function as it should).
