Given that having two identical functions in C is exceedingly rare (why
should a programmer write something like that?), I don't see that any
compiler vendor would invest his time in implementing this. There are
more interesting optimizations around.


If you're generating C code, you'll have to do this analysis yourself.
(Essentially, it's the same algorithm as the one that a C compiler would
have to employ.)
