hmm I feel it's out of scope for this PR but I feel the warning message is a bit obfuscated. The "leads to a dead code block" is true but it's an indirect consequence. I think it would be better to try to describe the direct consequence that inner condition s.empty() is always false.
I also feel that sometimes opposite inner conditions doesn't necessarily lead to dead code.. i.e.: if (x < 0 || s.empty()) I don't know if we warn but imho it should be OK to warn if the message is clear..
