Thu Nov 21 19:56:40 1991  Per Bothner  (bothner at cygnus.com)

	* stab-syms.c, syms.c:  Moved bfd_stab_name() and bfd_stab_names[]
	from syms.c to new file stab-syms.c.  Also, since GNU extended
	type codes such as N_SETT are no longer in ../include/stab.def,
	include them manually.
	* stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
	bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
	* libaout.h: Added prototype for aout_stab_name().
	* Makefile.in:  Update Makefile for new stab-syms.[co].

Thu Nov 21 11:50:49 1991  John Gilmore  (gnu at cygnus.com)

	* libaout.h (WORK_OUT_FILE_POSITIONS):  One more try at this
	rather complicated seeming problem.  Eliminate LOGICAL_ versions,
	just make N_XXX work by excluding the header from the text segment.
	* aoutx.h:  Fix comments to match.

Tue Nov 19 18:49:01 1991  Per Bothner  (bothner at cygnus.com)

	* libaout.h (WORK_OUT_FILE_POSITIONS):  Use new LOGICAL_TXTADDR,
	LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
	for the "logical" text segment (i.e. never consider the exec
	header to be part of the text segment).  This change is
	needed for consistency with various other parts of bfd and ld.
	* aoutx.h (NAME(aout,soe_aout_object_p)):  Fix comment,
	and move calculation of obj_textsec(abfd)->size to libaout.h.
	* bfd-in.h:  Removed bogus ';'.

	* Makefile.in:  Add MINIMIZE flag to select lean
	or bloated target_vector.
	* targets.c:  Use new MINIMIZE macro, and add trad_core if needed.
	* newsos3.c:  Fixes to ../include/aout64.h remove need
	for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.

Mon Nov 18 12:00:59 1991  Per Bothner  (bothner at cygnus.com)

	* aout-target.h, aoutf1.h, newsos3.c:  Make aout-target.h
	handle both little and big-endian targets, with little
	the default unless TARGET_IS_BIG_ENDIAN_P is defined.
	* host-aout.c:  Add FIXME note.

Sun Nov 17 13:29:39 1991  Per Bothner  (bothner at cygnus.com)

	* targets.c:  Make the default target_vector contain
	just &DEFAULT_VECTOR.  This makes executables a lot smaller.
	Old behavior can be gotten by defining ALL_TARGETS.
	* aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
	Factored out common code into new file aout-target.h.
	Saves a lot of duplicate code for a.out variants.

Fri Nov 15 13:00:43 1991  Per Bothner  (bothner at cygnus.com)

	Get 'make headers' to work when configured with +subdirs.
	* Makefile.in: Add $(subdir) to docdir path.
	* doc/Makefile.in (protos): Add $(srcdir) prefix
	to name of sed scripts.

Thu Nov 14 19:49:10 1991  Per Bothner  (bothner at cygnus.com)

	* aoutx.h (NAME(aout,print_symbol)):  Fix thinko.
	* syms.c (bfd_stab_names):  Turn on new GNU_EXTRA_STABS macro
	to include names of N_SETT etc.

Thu Nov 14 19:11:13 1991  Fred Fish  (fnf at cygnus.com)

    	* elf.c:  Add minimal support for ELF symbol tables.  Generates
	canonical bfd symbol tables from ELF symbol tables.  Change the
	name of some functions from bfd_<name> to elf_<name>.

	* syms.c:  Trivial fix to comment to remove a redundant "to".

Wed Nov 13 17:02:01 1991  John Gilmore  (gnu at cygnus.com)

	* coff-{i386,m68k,m88k}.c:  Change name of file format to standard
	form that GDB recognizes as COFF.

Wed Nov 13 09:09:41 1991  Steve Chamberlain  (sac at cygnus.com)

	* ieee.c (ieee_object_p):  cast NULL correctly.
	* configure.in: added harris host

	* coff-a29k.c: Lots of changes, most from David Wood.

Tue Nov 12 07:21:41 1991  John Gilmore  (gnu at cygnus.com)

	* coff-m88k.c (coff_write_armap):  Just #undef it.

Mon Nov 11 20:30:18 1991  Steve Chamberlain  (sac at cygnus.com)

	* Makefile.in: standardize on MINUS_G to disable debugging
	* coff-m88k.c: create coff armaps instead of bsd ones.
	* opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
	when calling chmod.

Mon Nov 11 19:07:32 1991  Fred Fish  (fnf at cygnus.com)

	* elf.c:  Additions to support ELF format core files.
	* config/mh-amix:  Add -DHAVE_PROCFS to HDEFINES, since host
	has support for /proc (all the include files in particular).

Mon Nov 11 18:36:47 1991  Per Bothner  (bothner at cygnus.com)

	* aoutx.h (NAME(aout,find_nearest_line)):  Handle the case
	of two N_SO stabs, one for directory, and one for filename.

	* bfd-in.h (print_vma):  Factor out duplicate definition.

	Exit a little more gracefully when malloc returns NULL.
	* libbfd.c: New function bfd_xmalloc (malloc wrapper).
	* opncls.c, syms.c, bout.c, aoutx.h:  Replace malloc by bfd_xmalloc.
	* libbfd.h: Rre-generated due to libbfd.c update.

Sat Nov  9 13:45:01 1991  Fred Fish  (fnf at cygnus.com)

	* config/mt-m68k-elf:  Define DEFAULT_VECTOR as elf_big_vec.

	* elf.c (elf_object_p):  Don't try to create a bfd section for
	the first ELF section header.  It is just a placeholder.

Sat Nov  9 03:04:26 1991  John Gilmore  (gnu at cygnus.com)

	* coff-rs6000.c, config/mh-rs6000:  Make it work on archive and
	core files, when compiling native.
	* hosts/h-rs6000.h:  Define FASCIST_FDOPEN for bfd_fdopenr.

	FIXME:  The aoutf1.h change below needs to be reversed back
	to the way it was.

Thu Nov  7 11:03:55 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	* coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
	manipulation of lnno fields in lineno structs in a coff-<f>.h
	independent way. Override it in coff-<f>.h to your favourite
	number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
	(coff_swap_lineno_out): modified to use the new macros.

Mon Nov  4 11:38:33 1991  Steve Chamberlain  (sac at cygnus.com)

	* aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
	unknown arch when the magic number doesn't specify the
	architecture, since some OSs (eg old sun3s) don't set the number, and
	020 is probably the right answer anyway.

Sun Nov  3 12:07:08 1991  Per Bothner  (bothner at cygnus.com)

	* hosts/h-news.h, hosts/h-rtbsd.h:
	Get rid of MISSING_VFPRINTF, since libiberty provides one.
	* bfd-in.h (bfd_print_symbol_type_hopw enum):   Add new option
	bfd_print_symbol_nm, for use by nm.
	* aoutx.h (NAME(aout,print_symbol)):  Add code for new
	bfd_print_symbol_nm option, to print in nm format.
	* coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
	oasys.c (oasys_print_symbol):  Provide stub implementations
	for bfd_print_symbol_nm.
	* syms.c:  New function bfd_decode_symclass, used by nm printer.
	New function bfd_stab_name to look up string name of stab code.

Sat Nov  2 14:26:03 1991  Steve Chamberlain  (steve at cygnus.com)

	* Makefile.in: Added ctor.c 
	* archures.c (bfd_default_arch_struct) added
	bfd_default_reloc_type_lookup.
	* coffcode.h: removed a load of #if 0ed code.
	(coff_compute_file_section_positions): now works out the section
	alignment and size correctly in all cases.
	(coff_get_symtab): looks for constructor symbols and calls the
	right function when they're found. (coff_canonicalize_reloc):
	knows when a section is full of constructors and does the right
	thing. 
	* cpu-m88k.c: Added default_reloc_type lookup to the architecture
	description.
	* libbfd-in.h: (bfd_default_reloc_type_lookup) defun  added.
	* libcoff.h: removed #if 0ed code
	* reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
	arch independent constructor relocation type.
	(bfd_reloc_type_lookup): removed the comment "this will go away"
	since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
	reloc which is used when BFD_RELOC_CTOR falls through to give a
	default 32bit reloc for constructors.
	(bfd_default_reloc_type_lookup): added.
	* aoutf1.h: fixed SEGMENT_SIZE typo.

Thu Oct 31 18:23:06 1991  John Gilmore  (gnu at cygnus.com)

	* coff-rs6000.c:  Change name to "aixcoff-rs6000", to avoid
	matching prefix "coff".
	* coffcode.h (coff_swap_aux_in, coff_swap_aux_out):  Handle
	rs/6000 csect records.

Sun Oct 27 16:56:58 1991  Steve Chamberlain  (steve at cygnus.com)

	* coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
	* configure.in: add motorola delta88 cases
	* libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
	write_armap prototype
	* libbfd.c: add doc on bfd_write_bigendian_4byte_int

Fri Oct 25 02:48:19 1991  John Gilmore  (gnu at cygnus.com)

	* Rename COFF-related files in `coff-ARCH.c' form.
	coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
	coff-mips.c, coff-rs6000.c to be exact.

	* Makefile.in:  Only supply TARGET_DEFAULTS to targets.c, reducing
	make output clutter.
	* config/mt-*:  Ditto.
