--- Comment #10 from Michael Brown <mc...@ipxe.org> --- (In reply to Ed Maste from comment #8) >From looking at elfcopy/binary.c and its create_binary() function: it appears that elfcopy will use sh_offset to calculate the position within the final binary file (rather than the LMA or even the VMA). Since sh_offset is meaningless once the ELF headers have been stripped away, this behaviour is provably incorrect for anything other than extracting a single section via "-j <section>". Building elfcopy from source confirms this behaviour from the current code. So, we have three possible behaviours: 1. binutils objcopy Uses the section LMA to determine the offset within the output file. As above, I would say that this behaviour is correct. 2. FreeBSD objcopy as present in binary distributions Uses the section VMA to determine the offset within the output file. As above, I would say that this behaviour is wrong. 3. FreeBSD objcopy as built from source Uses the section sh_offset to determine the offset within the output file. This behaviour is very definitely wrong. I am puzzled why I get different behaviour from the FreeBSD binary and source distributions, particularly since the use of sh_offset appears to have been present since 2010.
