Ah, now thats a better question .Sorry about the earlier answer, you are
not looking in the right place. 

What is in the rodata address that you refer to. ?Is it not that the
jump tables for the switch that you refer to.  Those are addresses into
the text sections. This particular part of the rodata would have its own
reloc entries. Do a objdump -Dr and look at the reloc values in rodata.
You can see the reloc values into the text around that place. 


Look at the relocation entries in the rodata section. The relocations
for the jump addresses would be in the rodata section and those will be
modified to the right address. Are these not addresses into the text
section ? 

Now is this clear ?

cheers
