2002-11-06 Klee Dienes <kdienes@apple.com>
* Makefile.am (BFD32_BACKENDS): Add mach-o.lo, pef.lo, and
xsym.lo.
(BFD32_BACKENDS_CFILES): Add mach-o.c, pef.c, and xsym.c.
(SOURCE_HFILES): Add mach-o.h, pef.h, pef-traceback.h, xsym.h
* archures.c (enum bfd_architecture): Add bfd_arch_m98k.
* 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.
* Makefile.in: Regenerate.
* doc/Makefile.in: Regenerate.
* bfd-in2.h: Regenerate.
* xsym.c: New file. Contains support for the Apple/Metrowerks
xSYM debugging format.
* xsym.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.

local symbols (static and debugging symbols) - grouped by module
defined external symbols - grouped by module (sorted by name if not lib)
undefined external symbols (sorted by name)

of symbols.

symbolic information tables:
table of contents
module table
reference symbol table
indirect symbol table

reference symbol table) are only present if the file is a dynamicly linked
shared library. For executable and object modules, which are files
containing only one module, the information that would be in these three
tables is determined as follows:
table of contents - the defined external symbols are sorted by name
module table - the file contains only one module so everything in the
file is part of the module.
reference symbol table - is the defined and undefined external symbols
For dynamicly linked shared library files this load command also contains
offsets and sizes to the pool of relocation entries for all sections

local relocation entries

entries of non-merged sections are not referenced through the section

a multiple of 4 32-bit word of zeroes in the instruction space. The traceback table is
also referred to as "procedure-end table".
The AIX traceback table representation on which this header is based is defined as a
series of bit field struct specifications. Bit fields are compiler dependent! Thus,
the definitions presented here follow the original header and the existing documentation
