I've looked into the objdump code, and the relevant code in BFD seems
to be the function pe_print_edata which seems to originate in
peXXigen.c. Unfortunately, this just dumps the info in text form, and
doesn't provide any kind of iterator or callback interface. On the
other hand, the BFD code looks a lot cleaner than the stuff I got out
of ld, so I'm considering copying this code instead.
Of course it would be good to share the code, but this kind of thing
won't fit into the generic BFD interface. One possibility would be to
expose a platform-specific interface from within the BFD internals.
Can anyone suggest a BFD maintainer to talk to about this?
