Hi,

     In my view, the linker.

     The compiler normally generates absolute addresses (starting from
0), creating object code.

     Then the linker generates an executable by combining different
object files together and assigning virtual addresses.

     Finally, is CPU (MMU) job (with the kernel helping) to translate
these virtual addresses to physical ones.

     Best regards,
