> "as binder can NOT discard a subset of a csect."?

Thanks, this does looks better!

> The linker (binder) doesn't have to discard a subset of csect, but it should ensure there are not two non-local symbols with the same name.
> The latter is what I request.



> Without section deduplication we just end up with PDP-11 a.out extended with .weak directive, it isn't too bad. Mach-O uses this model as well.
> (PE-COFF/ELF properly deduplicates in the absence of section based GC.)
> Having two non-local symbols could cause serious symbol resolution problems.

That I can definitely forward to AIX binder team, but we can't expect they implement it right away for us.
