[PATCH] D50488: [Analyzer] Checker for non-determinism caused by sorting of pointer-like keys

[Artem Dergachev via Phabricator via cfe-commits]

NoQ added a comment.

I guess one of the things the analyzer could find with path-sensitive analysis is direct comparison of non-aliasing pointers. Not only this is non-deterministic, but there's a related problem that comparison for equality would always yield false and is therefore useless. However, there will be many false negatives because most of the time it's hard to figure out if pointers alias by looking at a small part of the program (a call stack of at most 3-4 functions in the middle of nowhere), as the analyzer does.
