question about switch table

[ligang]

Hi,

Now, i wanna generate a switch table just like ARM tbb instruction.
The switch table should be located at .rdata section, so I should use 
.L3-.L8_1, but not .L3-.L8.
How could i implement this? Any target macro can do it?

Please look at the following code fragment. (.L3-.L8_1)/2 is what i want, 
but not .L3-.L8.

          la      r7, $L8
          tbb     [r7, r6]
  .L8_1
          .rdata
  .L8:
          .byte (.L3-.L8)/2 
          .byte (.L4-.L8)/2
          .byte (.L5-.L8)/2
          .byte (.L6-.L8)/2
          .byte (.L7-.L8)/2
          .text

Best regards
                     Ligang
