--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
f's code gen on the trunk is the best it could be:
        movl    (%rsi), %eax
        orl     (%rdx), %eax
        orl     (%rdi), %eax
        setne   %al
        movzbl  %al, %eax
        ret

Which was fixed by r14-1597-g64d90d06d2db43 .

f1 and f2 can't be transformed into f due to trapping possibility of loading
from j and l.
So marking this as fixed.
