<pre>Example (<a href="https://clang.godbolt.org/z/66YqsGEha">https://clang.godbolt.org/z/66YqsGEha</a>):
int f(unsigned i) {
if (i < unsigned(-1)) return i;
}
int g(unsigned i) {
if (i >= 0) return i;
}
compiled with clang++ -std=c++17 (no -Wall, no -Wextra) warns with
warning: non-void function does not return a value in all control paths
[-Wreturn-type]
for both functions.
AFAICT these warnings are false positives.</pre>
