```c
// Type your code here, or load an example.
unsigned square() { return -1.0; }
unsigned cube() { return (unsigned)-1.0; }
unsigned tesseract() { double num = -1.0; return num; }
```
Expected: All three compile to a single `ret` with -O2 (https://godbolt.org/z/bYjovz9nM), so I would quite like to see three warnings.
Actual: Only the first one warns.
