Practice Problem $7\mathrm{.}5($solution page $754)$

Consider the call to function swap in object file m$.$ o $($Figure $7\mathrm{.}5).$

$9$: $e800000000,$ callq $e,$swap$()$

with the following relocation entry:

$){86}_{64}{?}_{P}C32$

$r.$addend $=-4$

Now suppose that the linker relocates $.$ text in m$.$o to address $04004d0$ and swap

to address $04004e8.$ Then what is the value of the relocated reference to swap in

the callq instruction?
