早期freebsd实现

	* coff-rs6000.c:  Move core file functions into separate
	new file rs6000-core.c.  This is needed because reading
	core files depends on native include files that conflict
	with ../include/coff/rs6000.h.
	* config/mh-rs6000:  Add rs6000-core.o to HDEPFILES.

Thu Feb 27 22:19:55 1992  Per Bothner  ([e-mail])

	* aoutx.h (NAME(aout,print_symbol)): Don't print
	symbol addresss for undefined symbols.
	* coff-rs6000.c:  Various updates (due to target-
	independent changes).
	* libbfd.h:  Ditto (tdata field is now a union).
	* hosts/h-sparc.h:  Removed prototype for bogus function
	'emset' (presumably should have been 'memset' - which is there).

Thu Feb 27 11:46:33 1992  John Gilmore  (gnu at cygnus.com)

	* configure.in (mips-big-* target):  Same is Iris.

Thu Feb 27 09:24:56 1992  Steve Chamberlain  (sac at thepub.cygnus.com)

	* aoutx.h (translate_from_native_sym_flags): when creating an
	alias symbol, fill in the section as undefined, rather than
	leaving it blank. If an output section can't be found for a
	symbol, then don't core dump.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  ([e-mail])

	* Makefile.in, configure.in: removed traces of namesubdir,
	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
	  copyrights to '92, changed some from Cygnus to FSF.

	the symbol.flags and done_lineno fields.

Tue Feb 25 14:29:24 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	reloc.c, section.c (bfd_map_over_sections), targets.c
	(bfd_target_list):  Protolint.
	* libbfd.h:  Update to match a libbfd-in.h from a month ago.

Fri Feb 21 10:57:54 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* coffcode.h (coff_swap_aux_in): lint, (coff_print_symbol): prints
	out tagndx too.
	* aoutx.h (swap_std_reloc_out, swap_ext_reloc_out): use the output
	section of a symbol rather than the section of a reffed symbol to
	determine the r_index of an emmitted reloc.

Thu Feb 13 17:22:44 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* coffcode.h (get_normalized_symtab): fixed bug where symbols
	with more than one auxent can cause nasty core dumps. 

	* coffcode.h, libcoff.c: added new fielded to coff_symbol_struct
	"done_lineno" so that a symbol which appears twice in the symbol
	table only gets it's linenumbers relocated once. Modifed

	Specify byte order.

	* bfd-in.h, libaout.h:  ANSIfy enums.

Wed Dec 18 16:12:25 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	[-.foo]bar.obj;123 into bar.obj
	(bfd_construct_extended_name_table): now writes index into an
	extended name table in decimal - the same base used to read an

Wed Dec 18 14:40:39 1991  Per Bothner  (bothner at cygnus.com)

	* aout-encap.c:  Fix to use aout-target.h.

	host-specific a.out-related parameters.
	* Makefile.in:  host-aout.o depends on aout-params.h, which is
	generated by gen-aout.
	* aout-target.h:  Make a little more flexible.
	* libaout.h, aout-target.h:  Removed WORK_OUT_FILE_POSTIONS
	macro.  Instead, inline it in aout-target.h.

	remove unused variable.

	when it is not defined.

Mon Dec 16 12:00:10 1991  Fred Fish  (fnf at cygnus.com)

	* elf.c:  Flag all sections as either code or data.  We can't
	be sure what they are anyway, since ELF doesn't fit the
	traditional model of text+data+bss very well.  Add new local
	function elf_read() to simplify code.  Record entry point in
	the bfd structure.

Thu Dec 12 21:01:22 1991  John Gilmore  (gnu at cygnus.com)
