Grmpf.  Sorry, wrong machine used.  This was GCC 3.4.6.  4.1.0 is way
better:

..global test7
        .type   test7, @function
test7:
        rjmp .L2
..L3:
        out 59-0x20,__zero_reg__
..L2:
        sbic 57-0x20,6
        rjmp .L3
        rjmp .L12
..L5:
        out 59-0x20,__zero_reg__
..L12:
        sbis 57-0x20,6
        rjmp .L5
        rjmp .L13
..L7:
        out 59-0x20,__zero_reg__
..L13:
        sbis 57-0x20,6
        rjmp .L7
        rjmp .L14
..L9:
        out 59-0x20,__zero_reg__
..L14:
        sbis 57-0x20,6
        rjmp .L9
        ret
