The following patch adds support for the PEF, Mach-O, and xSYM file
formats. I've appended the patch to the existing code, as well as
attached a .tgz containing the new files.

-------------- next part --------------
Two cautions:
* Support for writing binaries is not provided for PEF or xSYM, and
has had only light use in the Mach-O target.
* Mach-O supports "fat" binaries with support for multiple platforms.
We've represented a fat binary as an archive (where each architecture
is a sub-file), which can lead to problems if you try to process an
archive of fat binaries (the current BFD code can only handle one level
of archive-ness). (We've got internal patches to BFD to support
infinite nesting of archives, but that's a matter for a different
patch.)
2002-10-07 Klee Dienes <kdienes@apple.com>
* Makefile.am (BFD32_BACKENDS): Add mach-o.lo, pef.lo, and
sym.lo.
(BFD32_BACKENDS_CFILES): Add mach-o.c, pef.c, and sym.lo.
archures.c (enum bfd_architecture): Add bfd_arch_m98k.
bfd-in2.h: Regenerate.
bfd.c (struct bfd): Add private data for mach-o, pef, and sym.
targets.c (enum bfd_flavour): Add flavours for mach-o, pef, and
sym.
(_bfd_target_vector): Add target vectors for mach-o, pef, and
sym.
sym.c: New file. Contains support for the Apple/Metrowerks xSYM
debugging format.
sym.h: New file.
pef.c: New file. Contains support for the Apple Code Fragment
Manager Preferred Executable Format
pef.h: New file.
pef-traceback.h: New file. Contains support for parsing PowerPC
traceback tables as used by PEF executables (and perhaps other
systems as well).
mach-o.c: New file. Contains support for the Mach-O object
file format.
mach-o.h: New file.
mach-o-target.c: New file. Declares the mach-o targets
themselves. Included three times by mach-o.c; each time with a
different set of macros set.
