Ian Lance Taylor
6812b6077e * targets.c (bfd_target): Rearranged fields in target vector.
Removed _bfd_debug_info_start, _bfd_debug_info_end and
	_bfd_debug_info_accumulate, which were never used.

	(BFD_JUMP_TABLE_CORE, BFD_JUMP_TABLE_ARCHIVE): Defined.
	(BFD_JUMP_TABLE_SYMBOLS, BFD_JUMP_TABLE_RELOCS): Defined.
	(BFD_JUMP_TABLE_WRITE, BFD_JUMP_TABLE_LINK): Defined.
	* All backends: Changed to use the new BFD_JUMP_TABLE_* macros
	rather than the single JUMP_TABLE macro.  Removed many of the
	weird macro definitions needed to support the monolithic
	JUMP_TABLE.

	functions, for use with the new BFD_JUMP_TABLE_* macros.

	bfd_error_nonrepresentable_section to nonrepresentable_section.

294eaca479 Some of these are guesses, if you know different, just yell.
Thu Oct  8 08:52:48 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	 Now a bfd knows whether underscores are normally prepended
	 to symbols in its file format. Helps with error messages.

	* aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c,
	coff-z8k.c: targets set so they have leading underscore
	* coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c,
	coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set
	without leading underscore flag
	* targets.c: add symbol leading char to xvec description
	* bfd-in.h (bfd_get_symbol_leading_char): new macro.

2cfd05621b * bfd-in.h: bump version to 1.96
Major change; changed calling convention for
	 bfd_get_relocated_section_contents so that caller allocates
	 memory for section data.
	* coffcode.h (bfd_coff_get_relocated_section_contents), reloc.c,
	seclet.c, targets.c, bfd.c: reflect new convention.
	* coffcode.h (styp_to_sec_flags): if styp_flags is not a special
	case, then use reasonable default values for SEC_* flags.

63ffe5ef86 Insert the incidentals and things I forgot to ci last time, same log message:
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.

	* amdcoff.c: (a29k_reloc) fix error message.

	* 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.
