That is what I get on x86 also now:
f:
        movl    i.1523, %eax
        pushl   %ebp
        movl    %esp, %ebp
        testl   %eax, %eax
        jne     .L2
        movl    $2, i.1523
        movb    $2, %al
.L2:
        popl    %ebp
        ret

But just change "== 0" to "!= 0" and you get the problem still.  Also this is a
code size issue for -Os as movl with a constant takes up too much space.
