[deliverable/binutils-gdb.git] / bfd / ChangeLog

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.

	* 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.
	
Mon Sep 30 13:31:15 1991  John Gilmore  (gnu at cygnus.com)

	* srec.c:  Better error checking, partly from Peter Schauer.
	(srec_object_p):  Avoid assuming any file that starts with 'S' is
	an S-record file!  (Check for 3 uppercase-hex digits after it.)
	(ISHEX):  Define new macro for checking supposedly hex characters.
	(pass_over):  Treat as EOF any S-record line that:
	    *  doesn't have hex in either size character
	    *  produces a size larger than 0x7F
	    *  has an unrecognized type number

Thu Sep 26 15:27:29 1991  John Gilmore  (gnu at cygnus.com)

	* aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,

	* newsos3.c: Fixed two types: newos3 -> newsos3.
	* reloc.c (bfd_perform_relocation): Fix pc-relative relocation
	to use correct segment.

Mon Sep 23 18:24:34 1991  Per Bothner  (bothner at cygnus.com)

	* aoutx.h (print_symbol):  Handle missing symbol->name.

Fri Sep 20 12:26:01 1991  Stu Grossman  (grossman at cygnus.com)

	* aoutf1.h (swapcore_sparc):  Change name of USRSTACK, fix comment
	at top of routine.

	(wood@nyu.edu).

	* opncls.c (bfd_fdopenr):  Handle NO_FCNTL.

	* Makefile.in:  Make subdirs work by using $(INCDIR) in the
	crude dependencies.

	(coff_find_nearest_line):  obj_icof => coff_data.
	(coff_swap_sym_{in,out}):  Check that SYMNMLEN == E_SYMNMLEN.
	(coff_swap_aux_{in,out}):  Check that FILNMLEN == E_FILNMLEN
	and DIMNUM == E_DIMNUM.
	* configure.in:  Handle a29k-*-* hosts, and targets 
	a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
	* libcoff-in.h:  Add local_n_btmask, local_n_btshft,
	local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
	local_linesz to `coff_data' (tdata) struct.	
	(coff_data, coff_data_type, coff_tdata):  Rename struct icofdata.
	* config/h-ultra3:  Handle a29k-*-* hosts as Ultracomputers.

	* all files:  update copyright notices for GPL version 2.
	Install header comments and attribute most modules to their
	authors.  BFD's name is now officially "Binary File Descriptor",
	so remove any conflicting pejoratives.

Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* ../include/bfd.h (struct bfd_target): Added new field
	"align_power_min" which contains the minimum alignment for a
	section. This is used in coff_new_section_hook. The field
	insertion necessitates an update of all backends..

	* aoutf1.h jump table field inserted
	
	* archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended

Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 
 	* coffcode.h (coff_swap_aux_in): added else case to deal with
 	filenames less than 9 characters.

	* ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
	
	* srec.c: now allows any number of sections to be created in a
	file. Outputs addresses of the right length.

Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* bfd.c (bfd_check_format): Fixed problem where when a defaulted
	target didn't match, the format got set to the attempted match,
	breaking a future test.

        *../include/i386coff.h : fixed typo in type field with size

	* i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
	support in the jump table for the swapping routines exported to
	gdb. Now gdb works with the 386.

	* Merge in changes from gdb-3.95 release.
	Makefile.in:  Allow hmake and tmake files to add OFILES.
	aoutf1.h:  
	bfd.c:  support specific targets as well as searching.  When
	searching, take default target in preference to others.
	bfd.doc:  typos
	ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
	liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
	libbfd.h:  Support specific targets as well as searching.
	opncls.c:  Support specific targets as well as searching.
	targets.c:  Search is short-circuited if default target matches.
	liboasys.c, libieee.c:  Undo bothner changes that make macros
	work to the left of assignment, but which depend on the
	representations of different pointer types being the same.

Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* i386coff.c: created.
	* coffcode.h: added support for 386. 
	* Makefile.in: added support for 386. 
	* ../include/i386coff.h: created

	(bothner)
	* opncls.c: Changed obstack_chunk_alloc use xmalloc

Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* everything: Removed sysdep.h from bfd.h and put back into files
	from which it was split out. Now 64 bit version is built with a
	-DHOST_64_BIT="long long" on the compile line.


Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	Changed all the [get|put][name] routines to use  [get|put]_[size
	in bytes].  

	Put in support for 64 bit work. Now two versions of bfd may be
	generated, according to the state of TARGET_64_BIT, one which is
	32 bit only, and one which is 64/32 bits. 
	Created new back end 'demo64' to test 64 bit functionality.

	Renamed some files to work on DOS.

	* archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
	64bit transfer 	* icoff.c: added 64bit transfer * ieee.c: name
	chage, 64 bit transfer. * liba.out.h: Split out common code from

	be called b.out.c * coffcode.h: used to be called coff-code.h, now
	64bit ized. * demo64.c: 64 bit a.out back end


	


Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
	from bothner
 	* libieee.h: Make ieee_data and ieee_ar_data macros usable
	on LHS of assignment, even when using old compilers.
	* liboasys.h: Ditto for oasys_data and oasys_ar_data.
	* m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
	* newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
	* opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
	* targets.c: Add declaration of newsos3_vec.


Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

	* aout.c: fixxed some of the problems with filepos calculation.
	(swap_ext_reloc): fixed problem with creation of relocs.
	(aout_set_section_contents): fixed filepos problem

	* coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
	(swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
	(swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
	(coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
	cleaned up. (coff_write_object_contents) cleaned up. 

	* ecoff.c: Totally different. Now supports ecoff fully.

	* icoff.c: fixed problems in relocation callout.

	* libcoff.h: (struct icofdata) removed hdr structure from tdata.

	* m68kcoff.c: updated target vector.

	* sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
	choose_reloc_size. (sunos4_write_object_contents) now calls
	choose_reloc_size so outputs relocs correctly, also calculates the
	size of the sections correctly.



Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Merge Per Bothner's changes to modularize BFD a.out a bit.

	* libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
	* ieee.c:  Cast enums to int before comparing them, for brain-
	dead compilers.
	* coff-code.h:  Remove coff_get_section_contents, and use the
	generic one instead.

	* aout.c:  Derive new module from sunos.c, containing generic
	support code for all kinds of a.out files.

	* sunos.c: Remove all code that goes in aout.c.  Split out
	machine dependent followup in sunos4_object_p into
	sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
	and redefine only the names we CHANGE, not all the names.  Drop
	the little-endian vector, and rename the vector as sunos4 rather
	than generic.

	* b.out.c:  Use aout.c routines for most of the work.  Slight
	changes for the new regime.  Remove close_and_cleanup and
	get_section_contents in favor of generics.  New transfer vector
	regime.

	* newsos.c:  New support for Sony NEWS, another a.out format.

	* ecoff.c:  Remove close_and_cleanup.  New tvec regime.
	* icoff.c, m88k-bcs.c:  Add write_contents to tvec.
	* ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
	to tvec. 
	* opncls.c (bfd_close):  Call format-dependent write_contents
	routine, if writing, before calling target-dependent
	close_and_cleanup routine (which is now always generic, I think).
	* srec.c:  Use bfd_alloc instead of malloc.  Remove
	close_and_cleanup and move code from it to
	srec_write_object_contents.  Add write_contents to tvec.
	* targets.c:  Remove a.out little vector, replace a.out big
	vector with SunOS vector.  FIXME:  Need Vax support again now.

	* libbfd.h:  Add write_contents format-dependent-vector to the
	bfd_target vector.  Supply a generic close_and_cleanup routine.
	* liba.out.h:  Handle the new aout.c split.  Add prototypes for
	all routines defined in aout.c.  Rename "sunos" things to "aout"
	things.  Add a few fields where needed for various formats.
	* Makefile.in:  Add aout.c and newsos.c.

	* archive.c, ieee.c, oasys.c:  Lint.

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.

   Notes on bfd-0.5.2-patch1a, from Per Bothner:

	* a.out.vax.c: Remove two bogus "static" from prototypes.

	* ecoff.c: Got rid of lots of non-working junk (that had
	been copied directly from coff-code.h).
	Updated to be consistent with updates to icoff.c and coff-code.h.

	* libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
	if they're missing (as they are in (BDS-4.3-based) NewsOS-3).

	* sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
	but until the target_vector is automatically generated,
	it's as good as any. Note that the text offset is the only
	difference between NewsOS and SunOs (including magic numbers).
	(Most of the sunos_* routines should to renamed bsd_*
	and move to a bsd.c file. Then (and when the target_vector
	is automatically generated) it might make sense to create
	a separate Sony target.)

	* sysdep.h: Don't declare fread and fwrite. Causes trouble
	on some systems, and doesn't help on others.
	Similarly, only define X_OK if not already defined.

	* trad-core.c: Don't include sys/stat.h - at least
	on NewsOS 3, it has already been included.

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

	canonicalize_reloc entry point.

	* libbfd.c fixed includes and added some lint patches.
	
	* targets.c added both sorts of intel coff.

	canonical symbols
		
	* sysdep.h created

	* coff-code.h fixed includes. Added code to support
	big and little endian formats. Various lints. Better
	processing of symbols. Changed reloc stuff to new
	order

	* libbfd.h fixed includes


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
	acessor macros. Added bfd_symbol_same_target macro.

	(bfd_make_section) took out initialization of obsolete members.
	(bfd_print_symbol_vandf) added

	* coff-code.h (coff_new_section_hook) took away refs
	to obsolete members. (make_a_section_from_file) added
	conversion between alignment types. (coff_symbol_from)
	added. (coff_count_linenumbers) only counts linenumbers
	if symbol is of coff-type. (coff_mangle_symbols) only
	heavily mangles symbols if symbol is coff-type.
	(coff_write_symbols) various lints. (coff_write_object_contents)
	various lints and modification for alignment conversion.
	(coff_slurp_relocs) fixed for use with new asection shape.

Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com

	* b.out.c added callj relocation support, upgrated reloc howto.
	Fixed so that asymbol and reloc records are output 
	correctly.

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

	* bfd.h changed definition of asymbol to contain pointer to

Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com

	* b.out.c removed prototype of sunos4_ennativate_symtab, lots of
	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
	macros.

	* bfd.c upgraded bfd_perform_relocation, various lints.

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

	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.
