Editing Unreachable code (section)

===Unreachability vs. profiling===
In some cases, a practical approach may be a combination of simple unreachability criteria and use of a [[Profiler (computer science)|profiler]] to handle the more complex cases. Profiling in general can not ''prove'' anything about the unreachability of a piece of code, but may be a good [[heuristic]] for finding potentially unreachable code. Once a suspect piece of code is found, other methods, such as a more powerful code analysis tool, or even analysis by hand, could be used to decide whether the code is truly unreachable.
