- Subject: Omit output section from executable
Hi all,
For an OS kernel I have put all CPU-local data in a specific ELF section named
".cpulocal". During bootstrap the kernel allocates a memory page for each CPU
and maps it to the VMA of the ".cpulocal" section.
I would like the linker to omit the (useless) contents of that section from the
executable while still maintaining references into the section. I can achieve
the desired effect by doing an objcopy -R .cpulocal after the final link.
Any way I could do the same with only a linker script and without the objcopy?
Thanks
- Udo
