Comment (by MikolajKonarski):

 I should mention that the semantics of `-fexpose-all-unfoldings` is
 currently different from `INLINABLE` on each function. In particular, it
 produces much slower programs for my codebase, probably because it doesn't
 force specialization (though it makes it possible by exposing the
 unfoldings), as opposed to `INLINABLE`.
