However, using "-O2 -m32 -fno-omit-frame-pointer" an unnecessary stack
adjustment remains, even after r208551:

test:
        movl    bar, %eax
        movl    (%eax), %edx
        testl   %edx, %edx
        jne     .L7
        ret
        .p2align 4,,10
        .p2align 3
        pushl   %ebp
        movl    %esp, %ebp
        subl    $20, %esp
        pushl   %eax
        call    foo
        addl    $16, %esp     <<<<
        leave
        ret
