I do not believe that this is true in the general case (although I have
not yet discovered a proof stating as such, yet). A while back I was
looking for algorithms for for reconstructing structured loops from
arbitrary basic block graphs for Clue, and every one I found was
surrounded by caveats stating that they didn't work in some circumstances.
(Which is one reason why I get irritated by languages that don't have a
working goto --- it makes the life of madmen like me who like playing
with code translation vastly harder.)
