I'm not sure if this works, but give it a try:

  asm ("\n\
        push %eax               \n\
        push %ebx               \n\
        push %ecx               \n\
        movl _data, %ebx        \n\
        xorl %eax, %eax         \n\
        xorl %ecx, %ecx         \n\
L_jump_label:                   \n\
        movl $0x0, (%ebx, %eax,)\n\
        addl $0x8, %eax         \n\
        addl $0x1, %ecx         \n\
        cmp  $0xa, %ecx         \n\
        jnz  L_jump_label       \n\
        pop  %ecx               \n\
        pop  %ebx               \n\
        pop  %eax               \n\
       ");

Hope that helps,
Long.
