Hi list,

I'm working on a BSD Licensed objcopy/strip rewrite(in p4) based on
libelf, I really want to know the answers to a few questions listed
below, and please do not hesitate if you have other related
suggestions. Thanks in advance!

1. Do you often use object/strip on 'ar' archives?

2. Do you often convert ELF to raw binary, iHex, S-Record or
vice versa?

3. What features do you like to add into objcopy?

4. What features would be useful for FreeBSD build system
and is currently missing in objcopy?

take a look at how we currently build firmware(9) modules (this concerns
2-4). Right now we use ld to convert a raw binary to something we can
link and have basic symbols to find the start and length of the binary.
This works, but not for all archs (ia64) and could be more comfortable.
I remember that we tried GNU objcopy at first, but it didn't give what we
were looking for - don't recall details, though. Let me know if you have
questions about this.
