Hi Arun,
Thanks for your response.
I will elaborate my question.Assume I have test.c file, I compiled test.c and generated the a.out ( Executable for linux ), when I do objdump of a.out, we can see addresses( virtual address ) associated with each instruction, these instructions are generated by whom?
Thanks

I didn't really get your question.
Linux kernel starts at a fixed location in virtual space. This is
called PAGE_OFFSET. On a kernel split of 3GB/1GB, 32 system, its is
0xC000_0000. You can have a look at system.map file after compiling
your kernel.
When cpu runs with MMU on, your cpu generates virtual address.

Arun
