I would convert the individual object files with bin2c and load them
with IMFS_make_linfile().
We stopped using rtems-bin2c in our project, because the performance was so poor
for larger files. Both bin2c and gcc were very slow.
I have experienced this as well.
Yes, the rtems-bin2c approach is only suitable for small files. For the
RTEMS test suite it is fine.
We've replaced that
workflow with something based on GNU AS `.incbin` instead, which is fast enough
to be unnoticeable.
I have used objcopy to copy a binary format file to the support ELF object file.
Doing this scales well and is almost fully portable across architectures, I
think the i386 needs a special option.
The problem with using objcopy is that you need to know the output
target (-O option). The output target may depend on the GCC multilib
(32-bit vs. 64 bit, big-endian vs. little-endian).
