Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)

	* cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
	cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
	files will eventually contain processor specific bits for bfd,
	like strange relocation information and dis/assembly.  So far only
	the H8 has been even partially done.  This work also ties in with
	the change in handling architectures.

	* aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
	discover the architecture of the bfd. (sunos4_callback) calls the
	function bfd_set_arch_mach rather than stuffing stuff directly
	into the bfd. (sunos4_write_object_contents), changed names of
	accessor functions.

	* aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
	setup the environment.

	* archive.c: (bfd_slurp_coff_armap) coff archives always have the
	headers in big endian format, regardless of the endianess of the
	host or target.

	* archures.c: totally changed. Now an architecture is represented
	with a pointer to an info structure rather than an enumerated type
	and a long. The old info is available as two elements in the
	structure.  Future enhancements to architecure support will
	involve pointers to methods being placed into the info structure.

	* bfd.c: changed the definition of the bfd structure for the new
	architecture stuff.

	* bout.c: (b_out_set_arch_mach) changed to use the new
	architecture mechanism.

	* coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
	the new architecture mechanism.

	* configure.in: added h8 stuff.

	* ieee.c: too many changes to note.  Now ieee files written with
	bfd gas and ld can be read by gld and ieee only linkers and
	simulators.

	* libbfd.c, libbfd.h: changed prototype of bfd_write.

	* newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
	than fixing the structure directly.

	* oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
	than fixing the structure directly.

	* opncls.c: (new_bfd) makes sure that bfd_init has been called
	before opening a bfd.

	* srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
	rather than fixing the structure directly.

	* targets.c: (target_vector) now by defining SELECT_VECS (perhaps
	in the t/hmake file) a user can select which backends they want
	linked with bfd without changing the source.

	* init.c: new, looks after initializing modules.

	* howto.c: for future use, will allow an application to work out
	what cookie to use as a handle on a relcoatio howto.
