Actually you don't need recompiling: simply set a breakpoint at the 
entry of relocate_code and once you hit the bp, look up r2: it contains 
the destination. If you want the offset rather than the absolute 
address, set the breakpoint right after the 'sub r9, r6, r0' round line 
222: r9 will then give you the offset. Unload the current symbols, 
reload the symbols with the relevant offset, and there you go.
