_bfd_elf_parse_eh_frame() should not assume relocation order?

Yes, in order to post-process the resulting object file localize the symbols 
for interfaces private to a module - limiting the exposure of interfaces.

But that was not the question:

The question was, is it allowed to do so? Why shouldn't it sort the 
relocations when writing the resulting object if it expects such ordering on 
input?

The `info ld' states the following about the -r option:

     Generate relocatable output--i.e., generate an output file that can
     in turn serve as input to 'ld'.  This is often called "partial
     linking".

I don't see how this description can be interpreted to say "`ld -r' can mess 
things up to the point ld itself will produce errors when trying to link the 
object file previously produced by ld".

So, is it a bug in BFD?
