// error-pattern: In non-returning function f, some control paths may return
fn f() -> ! { ret 42; fail; }
fn main() { }
Handle fail after return correctly in typestate Previously, typestate would conclude that this function was correctly diverging: fn f() -> ! { ret; fail; } even though it always returns to the caller. It wasn't handling the i_diverge and i_return bits correctly in the fail case. Fixed it.
