objcopy --redefine-sym does not rename undefined symbols

[Nicolas Williams]

I need to be able to rename undefined symbols (don't ask :/ ).

I also would like to be able to manipulate recorded dependencies,
rpaths, etc... This last I think I can get with ld anyways, but it would
be nice if objcopy could handle it.

Having zero experience with libbfd but otherwise being able to program
C, what are my chances of being able to fix objcopy or add an option to
rename undefined symbols? What about dependency manipulation?

Would there be any patches floating around that might provide the
functionality I seek?

Also, can the output of objdump generally be re-assembled into an
object file equivalent to its input?

The version of objcopy I'm using is 2.10.1.

Thanks,

Nico

Works with current CVS and 2.12 objcopy.

No.  Some targets are quite close, eg. x86, others need quite a bit
of work in an editor.
