It's also subject to how hard the compiler feels like trying in any given
release.  Many compilers have simple unreachable code warnings.

But to do a 100% accurate job of yield detection would be equivalent to the
halting problem, which is a classic problem in computer science that cannot
be solved 100% accurately in finite time.
