questions about overlay support in GNU ld

[Tao Zhang]

Dear all,

I am trying to fit potentially very big programs into a very limited local
storage. So we need to something like overlaying. I know GNU ld supports
overlaying, but does it support function calls between overlays, by any
means? We cannot limit our program partitioning too much so we have to
support calls between overlays. If GNU ld currently doesn't support that,
could someboy give me some pointers on how to implement it? Like related
code pieces in GNU ld I should study etc.?

Thanks so much!

Tao
