--- Comment #1 from Avi Kivity <avi at scylladb dot com> ---
btw, I see that the equivalent bool_and generates optimal code.

bool_and(bool, bool):
        movl    %esi, %eax
        andl    %edi, %eax
        ret

Perhaps bool is written with the expectation that any non-zero value is true?
But aren't non-zero values other than 1 undefined behavior?
