For an operating system that supports a paging system, does a compiler need to support

relocatable addresses? Explain.

No $-$programs are virtualized so that they can start at address $0$ and the paging system will take care

of placing them in physical memory

Yes $-$otherwise it won't be possible to trigger an exception when the limit register is exceeded.

No$-$any compiler can be used to build programs for any operating system

Yes $-$a paging system cannot be implemented without relocatable address support.
