Translate the following high-level language code segment to ARM assembly language. Use the registers indicated in the code.

while (R8 > 20) do

       if (R8 < 100) OR (R8 > 200) then

           R7 = R8

           R8 = R8 - 10

      else

           R8 = R8 - R7

      end if

      R7 = R6 + 4

end while
