早期freebsd实现

	  nows works in objdir always so make file existence checks
	  against ${srcdir}.

Thu Dec  5 22:46:19 1991  K. Richard Pixley  (rich at rtl.cygnus.com)

	* Makefile.in: idestdir and ddestdir go away.  Added copyrights
	  and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
	  and mandir now keyed off datadir by default.

Wed Dec  4 10:14:17 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	* aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
	computation of arch and machine type so it's worked out before
	some_aout_object_p is called. 
	* aoutx.h: (some_aout_object_p): don't set arch and mach to
	unknown.
	* archures.c: add extra field 'section_align_power' to hold
	default section alignment in object files.
	* cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
	cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
	initialize the new field.
	* bout.c (b_out_callback): replace the text size, since aout
	fries them.
	* aoutx.h: Documentation in the new style

Wed Dec  4 02:00:30 1991  John Gilmore  (gnu at cygnus.com)

	* bfd.c (bfd_get_mtime):  Don't cache mtime any more; only
	use the saved value if mtime_set is already set (intended
	for archive files, though apparently not used yet).

Tue Dec  3 22:54:50 1991  John Gilmore  (gnu at cygnus.com)

	* targets.c:  Revise comments about how to configure the target
	vector, to match reality.  Remove mention of obsolete methods.
	Remove long lists of capitalized macros that turn into the same
	thing in lowercase.  Normal vector simply lists all known
	lowercase xvec names; all other cases are handled by SELECT_VECS.

	* config/mt-i386-coff:  Set DEFAULT_VECTOR to real identifier,
	not macro name.

	* config/mt-i960-{coff,bout}:  Use SELECT_VECS to make a short
	list of supported targets.

Tue Dec  3 14:06:15 1991  Per Bothner  (bothner at cygnus.com)

	* archive.c (bsd_write_armap):  The pad byte sometimes added to
	the string table in a __.SYMDEF member is now
	counted as part of the size of the string table.
	This is compatible with the old ranlib, as well as Sun's.

Tue Dec  3 10:53:30 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	* srec.c: Rewrote to fix many bugs; now gets the record type
	right, doesn't choke on input, sets the start address in an S9 and
	fills in the filename on an S0.

Sat Nov 30 21:19:15 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	* cpu-h8300.c: Add support for MEMIND addressing mode

	* coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
	coffcode.h
	* coffcode.h: use the new macro if available

	* elf.c (elf_corefile_note): cast malloc to avoid warning.
	* Makefile.in: Fixed dependencies due to file rename

	* aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
	coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
	coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
	newos3.c, stab-syms.c, syms.c: All these files have had their
	#includes altered to point to the new places.

Fri Nov 29 20:04:49 1991  Fred Fish  (fnf at cygnus.com)

	* config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h:  New files.

	* configure.in:  Add vendor "ncr" as supported per-target vendor.
	Add svr4 case for i386 per-host case.

	* elf.c (elf_object_p, elf_core_file_p):  Add missing "break" to
	ELFDATA2LSB cases.

Fri Nov 29 12:16:51 1991  Per Bothner  (bothner at cygnus.com)

	* syms.c (bfd_decode_symclass):  Return 'A'
	for symbols that are both absolute and global.
	* archive.c (bfd_special_undocumented_glue):  Return NULL
	if bfd_ar_hdr_from_filesystem returns NULL.

Tue Nov 26 09:10:55 1991  Steve Chamberlain  (sac at cygnus.com)

	* Makefile.in: added coff-h8300
	* configure.in: now h8 is a coff target
	* cpu-h8300.c: fix various disassembly problems
	* libcoff.h: took out some code which has been #0ed for a long
	time.
	* targets.c: added h8 coff 
	* coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
	added new macro RTYPE2HOWTO to take a load of #ifdefs out of
	coffcode.h
	* coffcode.h: Started to change the way machine dependencies are
	handled, from the nest of #ifdefs to macros defined in the
	including coff-<foo>.c

Fri Nov 22 08:11:42 1991  John Gilmore  (gnu at cygnus.com)

	* aoutx.h (some_aout_object_p):  Set the `executable' bit
	if the entry point is contained in the text segment, even if the
	text segment is at location 0.

	* coff-mips.c, coffcode.h:  Peter Schauer's patch to kludge in
	nonstandard MIPS sections (.rdata, .sdata, etc).

	* aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
	* libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
	Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
	* libbfd.c:  Lint.
	* host-aout.c, trad-core.c:  Fix write_armap prototypes.  Lint.

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.

Thu Oct 24 22:40:07 1991  John Gilmore  (gnu at cygnus.com)

	RS/6000 support, by Metin G. Ozisik, Mimi Ph
