In general, C semantics require that a function invocation's value
parameters be unique to the activation record.  They cannot be shared.

Your particular example would allow that optimization, IF all users of
the function were known to the compiler at the point that it was
deciding what form of function linkage to use for that function.
However, it is doubtful that the extra analysis and irregular linkage
mechanism would be worthwhile for such an unlikely case.
