> In some (many?) cases the null test is eliminated by
> -fdelete-null-pointer-checks as a consequence of the pointer having been
> dereferenced. What remains is the cases where GCC doesn't see any such
> dereferences. It would be interesting to get an idea of what proportion
> they constitute and how much they or their removal might contribute to the
> size and efficiency of code. David Malcolm's remarks could help reveal some
> of these data points.
