Oops... I forgot the last chunk:

FirstOne:
        add     %sp, -120, %sp
        std     %o0, [%sp+96]
        sllx    %o0, 32, %o0
        srl     %o1, 0, %o1
        or      %o1, %o0, %o0
        srlx    %o0, 48, %o1
        srlx    %o1, 32, %o0
        orcc    %o0, %o1, %g0
        be,pt   %icc, .LL2
         nop
        sethi   %hi(first_one), %g1
        sub     %sp, -120, %sp
        or      %g1, %lo(first_one), %g1
        jmp     %o7+8
         ldub   [%g1+%o1], %o0
.LL2:
        ld      [%sp+96], %o0
        jmp     %o7+8
         sub    %sp, -120, %sp
