Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* ../include/bfd.h
	changed forward declaration struct stat; to reduce warnings. Changed
	comment on bfd_h_<x>_x.

	* ../include/m68kcoff.h, ../include/intel-coff.h,
	../include/m88k-bcs.h
	Now there are two incarnations of relocs, linenos and syments. One for
	internal digestion, and one full of char arrays for I/O. The original
	names have gone to detect errors.

	* Makefile.in, m68kcoff.c, targets.c
	Test new structure code with a 68k coff implementaion

	* coff-code.h, icoff.c, coffswap.c, libcoff.h 
	Fixed all the places where there were problems with the size and
	alignments of structures on disk and structures in memory. #ifed out
	all the code in coffswap.c, since it should be done using the target
	swap routines now.


Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* ieee.c (do_one, ieee_slurp_section_data): now supports the load
	multiple reloc command.

	* sunos.c (sunos4_set_section_contents): Made it so that sections
	are always padded to their alignment size.

Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
	Clean up types and such (saber C problems).
	* ecoff.c:  Clean up types and such.  Remove routines that are
	not used.  Fix up reading and swapping of shorts from files.

Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
	bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
	symbol tables if necessary when reading them in, so gdb can use
	them.  Add "bfd_coff_" to the names so they won't conflict with
	names in calling programs.  FIXME-soon:  if coff-code.h is
	included in two BFD modules, this will cause duplicate
	definitions; the routines should be exported to a separate,
	common, module (probably along with a mess of other ones).

Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Improve modtime support.

	* bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
	Remove #define for bfd_get_mtime.  Remove gratuitous comment.
	* bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
	BUG:  archive members still do not get correct mod times.

	Improve floating point support for core files.

	* sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
	(sunos4_core_file_p):  Create a second registers section in the
	core file, called ".reg2", for the float registers.

Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

	* many changes to improve archive handling; found a logic flaw in
	  bfd_check_format which only just happened to work by cooncidence.

Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* bfd.c (bfd_perform_relocation): fixed to use output_offsets
	correctly.
	
	* bfd.h: changed type of udata in asymbol to void *, like it
	should be. Added bfd_reloc_dangerous enum member.

	* coff-code.h: Fixed it so that internally generated symbols get
	their values relocated correctly in all cases. Removed calls to
	xmalloc.

	* icoff.c: Not understanding the destination symbol of a reloc is
	not a failure any more, just 'dangerous'. This allows linking of
	b.out and coff images.

	* sunos.c: Cleaned up the way that ZMAGIC section sizes are
	calculated.


Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* sunos.c (translate_to_native_sym_flags): fixed
	sym_pointer->n_value so that symbols on the way out get their
	section relative values calculated correctly.

	* coff-code.h (mangle_symbols): fixed problem where tags were not
	being relocated for structs, enums, unions. Also various lints.

Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

	* archive.c (get_elt_at_filepos): system_call_error returned
	  incorrectly.

Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

	* Resolve the use of no_error and system_call_error.
	  The bfd library itself now will never set bfd_error to
	  no_error.

	  The code still needs to be combed to make sure all the error
	  codes are correct.  I suspect they are not always set correctly.

	* The names of all the messages have _ prepended because the sun
	  bundled compiler can't distinguish from a macro which takes an
	  argument and the same identifier in a non-macro context.

	* The reason for the above being that entry points which used to
	  be trampoline functions are now just macros which expand to a
	  direct call through the bfd's xfer vector.

	* (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
	  must gas have its own version of everything (the gas version
	  had the correct value)

Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
	properly support i960 architecture and output correct reloc stuff.

	* bfd.h: added prototype for bfd_printable_arch_mach, added
	BFD_FAIL

	* coff-code.h: Applied patches from chrisb to support i960
	architecture, zero relocs and swap them correcly and conditionally
	compiled the timestamp.

	* sunos.c: Made the default section alignment 2^3 so that doubles
	are done properly. Fixed the same reloc bug that was in b.out.c

	* sysdep.h: Now compiles on a Posix box

Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* icoff.c:  Fix comment on big-endian version.
	* coff-code.h:  Make HAS_RELOC really work (it's backwards from
	F_RELFLG).  Set F_AR32WR in output files if little endian
	architecture.

Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
	
	* archures.c fixed =/== typo
	
	* sunos.c added architecture stuff for output. Fixed
	bug where files where vma(data) != size(text) 
	were processed wrong.

	* coff-code.h added a lint cast

	* (../include/a.out.sun4.h) fixed it so zmagic
	worked

Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
	
	* bfd.h	changed name of alignment entry in sec_struct to
	alignment_power, because of conflicting uses within bfd.
	Now it should be obvious that it's a 2**n alignment
	specifier. Removed start_pad, end_alignment, block, minsize,
	output_file_alignment, subsection_alignment and original_vma fields.
	Added align_power() macro. Fixed bfd_section_alignment

	to obsolete members. (make_a_section_from_file) added
	conversion between alignment types. (coff_symbol_from)
	added. (coff_count_linenumbers) only counts linenumbers

	correctly.

	* bfd.c lots of lint, support for new bfd entry point
	bfd_print_symbol.

	pointer lint. Added support for callj relocation. Fixed bug where
	the last 32 bytes of the text section were overwritten by data. Fixed bug
	where archives of b.out didn't work due bfd_slurp_extended_name_table
	returning false.

	* sunos.c added support for n_other field. Braced the howto table so
	that it won't be affected by any lengthing of the howto struct typedef.
	Various lints

	* bfd.h added support for n_other field, added special_function 	
	reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)

	* ChangeLog:  Started ChangeLog for BFD.
	* ToDo:  Create file for suggestions.

	* Makefile:  Support easy loading into Saber C.
	Add dependencies for icoff.o and bcs88kcoff.o.
	Rename coff.c to coff-code.h.  Change callers.

	* bfd.c (bfd_check_format):  Allow the check_format routines
	to return the desired target vector, rather than just a Boolean.
	bfd.h (bfd_check_format):  Change function pointer return type.
	archive.c (bfd_generic_archive_p):  change callee.
	b.out.c (b_out_little_object_p, b_out_big_object_p,
	b_out_real_object_p):  change callee.
	libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
	in check_format transfer vectors that need a filler.
	libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
	bcs88kcoff.c:  change callee.
	coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
	icoff.c:  change callee.
	sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.

	* libbfd.c (zalloc):  It should actually zero the storage!
	This was commented out for some reason.

	* libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
	This is so callers can avoid <stdlib.h> which doesn't exist
	on older systems.

	* bfd.c (map_over_sections):  Add debugging code, since I
	noticed the section count for sunos core files was bad, but only
	GDB had detected the problem.
	(bfd_set_section_lineno_size, bfd_set_section_linenos,
	bfd_get_section_linenos):  Remove obsolete functions.

	as typedefs for them.  Remove obsolete
	bfd_get_section_lineno_size.

	* cache.c:  Make the "fdopen" support work.  Keep better track
	of how many files are open.  Centralize the opening of files
	and be sure bfd_open[rw] actually try to open the file.  Evade
	linked list initialization problems.

	* b.out.c, coff-code.h, opncls.c, sunos.c:  lint.

	* coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.

	* cplus-dem.c:  Delete file, since it is not part of BFD.

	* opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
	(bfd_openr, bfd_openw):  Actually open the file, give error now.
	
	* sunos.c (sunos4_core_file_p):  Set section count.
	(sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
	obsolete definitions.
	(_write_symbol_table):  Initialize <idx> counter.
	(foop):  Eliminate debugging code.
