bfd/ChangeLog

   1 Tue Oct  1 05:02:53 1991  John Gilmore  (gnu at cygnus.com)
   2
   3         Vax Ultrix changes from David Taylor <taylor@think.com>:
   4         * host-aout.c:  Make little-endian vector really little-endian.
   5         * configure.in:  Separate vax and tahoe cases, handle ultrix.
   6         * config/t-vax:  Add trad-core.o.
   7         * config/h-vaxult:  New host system.
   8
   9 Mon Sep 30 15:13:46 1991  Steve Chamberlain  (steve at cygnus.com)
  10
  11         * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
  12         cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
  13         files will eventually contain processor specific bits for bfd,
  14         like strange relocation information and dis/assembly.  So far only
  15         the H8 has been even partially done.  This work also ties in with
  16         the change in handling architectures.
  17
  18         * amdcoff.c: (a29k_reloc) fix error message.
  19
  20         * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
  21         discover the architecture of the bfd. (sunos4_callback) calls the
  22         function bfd_set_arch_mach rather than stuffing stuff directly
  23         into the bfd. (sunos4_write_object_contents), changed names of
  24         accessor functions.
  25
  26         * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
  27         setup the environment.
  28
  29         * archive.c: (bfd_slurp_coff_armap) coff archives always have the
  30         headers in big endian format, regardless of the endianess of the
  31         host or target.
  32
  33         * archures.c: totally changed. Now an architecture is represented
  34         with a pointer to an info structure rather than an enumerated type
  35         and a long. The old info is available as two elements in the
  36         structure.  Future enhancements to architecure support will
  37         involve pointers to methods being placed into the info structure.
  38
  39         * bfd.c: changed the definition of the bfd structure for the new
  40         architecture stuff.
  41
  42         * bout.c: (b_out_set_arch_mach) changed to use the new
  43         architecture mechanism.
  44
  45         * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
  46         the new architecture mechanism.
  47
  48         * configure.in: added h8 stuff.
  49
  50         * ieee.c: too many changes to note.  Now ieee files written with
  51         bfd gas and ld can be read by gld and ieee only linkers and
  52         simulators.
  53
  54         * libbfd.c, libbfd.h: changed prototype of bfd_write.
  55
  56         * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
  57         than fixing the structure directly.
  58
  59         * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
  60         than fixing the structure directly.
  61
  62         * opncls.c: (new_bfd) makes sure that bfd_init has been called
  63         before opening a bfd.
  64
  65         * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
  66         rather than fixing the structure directly.
  67
  68         * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
  69         in the t/hmake file) a user can select which backends they want
  70         linked with bfd without changing the source.
  71
  72         * init.c: new, looks after initializing modules.
  73
  74         * howto.c: for future use, will allow an application to work out
  75         what cookie to use as a handle on a relcoatio howto.
  76
  77 Mon Sep 30 13:31:15 1991  John Gilmore  (gnu at cygnus.com)
  78
  79         * srec.c:  Better error checking, partly from Peter Schauer.
  80         (srec_object_p):  Avoid assuming any file that starts with 'S' is
  81         an S-record file!  (Check for 3 uppercase-hex digits after it.)
  82         (ISHEX):  Define new macro for checking supposedly hex characters.
  83         (pass_over):  Treat as EOF any S-record line that:
  84             *  doesn't have hex in either size character
  85             *  produces a size larger than 0x7F
  86             *  has an unrecognized type number
  87
  88 Thu Sep 26 15:27:29 1991  John Gilmore  (gnu at cygnus.com)
  89
  90         * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,

  92
  93 Thu Sep 26 11:24:24 1991  Per Bothner  (bothner at cygnus.com)
  94
  95         * libaout.h (WRITE_HEADERS): Set header's a_text field always.
  96         * newsos3.c: Fixed two types: newos3 -> newsos3.
  97         * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
  98         to use correct segment.
  99
 100 Mon Sep 23 18:24:34 1991  Per Bothner  (bothner at cygnus.com)

 125         current file's coff symbol format to BFD via the coff_data struct.
 126         (coff_find_nearest_line):  obj_icof => coff_data.
 127         (coff_swap_sym_{in,out}):  Check that SYMNMLEN == E_SYMNMLEN.

 165         to h/t-xxxx files so that everything will work on System V.
 166
 167 Fri Aug 23 13:51:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
 168
 169         * aoutx.h:  Add information on host-aout.c and how to configure
 170         to use it, to the manual.
 171         * configure.in:  Tix typo.
 172         * ecoff.c:  If compiling for DEC3100, use trad_unix core files,

 176         * coffcode.h (coff_write_symbols):  Declare buffer as bfd_bytes
 177         rather than as chars (lint).
 178

 188
 189
 190 Wed Aug 21 19:13:22 1991  John Gilmore  (gnu at cygint.cygnus.com)
 191
 192         * trad-core.c (trad_unix_core_file_p):  Use HOST_TEXT_START_ADDR,

 201
 202 Wed Aug 21 14:33:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 203
 204         * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
 205         texdoc and psdoc; make these depend on generated .texi's
 206
 207         * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
 208         doc

 215         libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
 216         libbfd.h, and libcoff.h; (b) in generated parts of same, use less
 217         obtrusive marks indicating .c origins.
 218
 219         * bfd.texinfo: generalize most references to linker
 220
 221 Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 222
 223         * Makefile.in: include core.p in PROTOS (building better bfd.h)

 225
 226 Mon Aug 19 13:48:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 227
 228         * bfd.texinfo: use @setchapternewpage on instead of lots of
 229         @page's; minor rephrasing in Introduction.

 239
 240         * coffcode.h: fixed bug where string table size wasn't being swapped.
 241
 242 Thu Aug  1 16:35:28 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 243
 244         * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags
 245
 246         * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT
 247         flags. (bfd_print_symbol_vandf) now knows what to do with the
 248         above flags.
 249
 250         * aoutx.h: made translate_from_native_sym_flags and
 251         translate_to_native_sym_flags produce the above flags.
 252
 253
 254 Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
 255
 256         * all files:  update copyright notices for GPL version 2.
 257         Install header comments and attribute most modules to their
 258         authors.  BFD's name is now officially "Binary File Descriptor",
 259         so remove any conflicting pejoratives.
 260         archures.h:  Consists solely of comments; remove it.
 261
 262 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 263
 264         * Makefile.in, bfd.c: Made it compile again.
 265
 266 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 267
 268         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
 269
 270

 275         lint fixes.
 276
 277         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
 278         29k coff by David Wood (wood@lab.ultra.nyu.edu).
 279
 280 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 281
 282         * Everything: created some new files, core.c format.c, reloc.c,
 283         section.c and syms.c to split the functionality a bit better.
 284         Cleaned up the rest of the files a bit, and added some
 285         documentation.
 286
 287
 288 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 289
 290         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
 291         really takes 3 arguments, patched code and ammended prototypes.
 292
 293 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 294
 295         * ../include/bfd.h (struct bfd_target): Added new field
 296         "align_power_min" which contains the minimum alignment for a
 297         section. This is used in coff_new_section_hook. The field
 298         insertion necessitates an update of all backends..
 299
 300         * aoutf1.h jump table field inserted
 301
 302         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 303         filenames too.
 304
 305         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 306         table field inserted.
 307
 308         * coffcode.h(just about everything) Now patches up symbol tables
 309         using a different mechanism. The Intel major bug has been fixed,
 310         and the linker can self host on the Aviion and be debugged with
 311         gdb.
 312
 313         * ecoff.c: new include and jump table patch, i386coff.c: new
 314         include and jump table patch,  icoff.c: new include and jump table
 315         patch, ieee.c: can now read archives containing ieee modules.,
 316         libcoff.h: added (combined_entry_type), libieee.h: uped max
 317         sections to 20, m68kcoff.c: new include and jump table patch,
 318         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 319         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
 320         srec.c: jump table patch. trad-code.c fixed #IF typeo
 321
 322 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 323
 324         * coffcode.h (coff_swap_aux_in): added else case to deal with
 325         filenames less than 9 characters.
 326
 327
 328 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 329
 330         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 331
 332         * srec.c: now allows any number of sections to be created in a
 333         file. Outputs addresses of the right length.
 334
 335 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 336
 337         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 338         target didn't match, the format got set to the attempted match,
 339         breaking a future test.
 340
 341         *../include/i386coff.h : fixed typo in type field with size
 342
 343         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 344         support in the jump table for the swapping routines exported to
 345         gdb. Now gdb works with the 386.

 347 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 348
 349         * Merge in changes from gdb-3.95 release.
 350         Makefile.in:  Allow hmake and tmake files to add OFILES.
 351         aoutf1.h:
 352         bfd.c:  support specific targets as well as searching.  When
 353         searching, take default target in preference to others.
 354         bfd.doc:  typos
 355         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 356         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 357         libbfd.h:  Support specific targets as well as searching.
 358         opncls.c:  Support specific targets as well as searching.
 359         targets.c:  Search is short-circuited if default target matches.
 360         liboasys.c, libieee.c:  Undo bothner changes that make macros
 361         work to the left of assignment, but which depend on the
 362         representations of different pointer types being the same.
 363
 364 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 365
 366         * i386coff.c: created.
 367         * coffcode.h: added support for 386.
 368         * Makefile.in: added support for 386.
 369         * ../include/i386coff.h: created
 370
 371 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 372
 373         * coffcode.h: removed all put_x_<sizes>
 374         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 375         DEFUNS
 376
 377
 378 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 379         (bothner)
 380         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 381
 382 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 383
 384         * everything: Removed sysdep.h from bfd.h and put back into files
 385         from which it was split out. Now 64 bit version is built with a
 386         -DHOST_64_BIT="long long" on the compile line.
 387
 388
 389 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 390
 391         Changed all the [get|put][name] routines to use  [get|put]_[size
 392         in bytes].
 393
 394         Put in support for 64 bit work. Now two versions of bfd may be
 395         generated, according to the state of TARGET_64_BIT, one which is
 396         32 bit only, and one which is 64/32 bits.
 397         Created new back end 'demo64' to test 64 bit functionality.
 398
 399         Renamed some files to work on DOS.
 400
 401         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 402         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 403         chage, 64 bit transfer. * liba.out.h: Split out common code from
 404         sunos and newsos into liba.out. Name changes and prototype mods. *
 405         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 406         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 407         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 408         change and 64bit stuff.* newsos3.c: common code removed, new jump
 409         table. * oasys.c: Name change * opncls.c: Portability fixes *
 410         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 411         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 412         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 413         64bit ized. * demo64.c: 64 bit a.out back end

 418
 419 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 420         from bothner
 421         * libieee.h: Make ieee_data and ieee_ar_data macros usable
 422         on LHS of assignment, even when using old compilers.
 423         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 424         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 425         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 426         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 427         * targets.c: Add declaration of newsos3_vec.
 428
 429
 430 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 431
 432         * aout.c: fixxed some of the problems with filepos calculation.
 433         (swap_ext_reloc): fixed problem with creation of relocs.
 434         (aout_set_section_contents): fixed filepos problem
 435
 436         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 437         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 438         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 439         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 440         cleaned up. (coff_write_object_contents) cleaned up.
 441
 442         * ecoff.c: Totally different. Now supports ecoff fully.
 443
 444         * icoff.c: fixed problems in relocation callout.
 445
 446         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 447
 448         * m68kcoff.c: updated target vector.
 449
 450         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 451         choose_reloc_size. (sunos4_write_object_contents) now calls
 452         choose_reloc_size so outputs relocs correctly, also calculates the
 453         size of the sections correctly.
 454
 455
 456
 457 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 458
 459         Merge Per Bothner's changes to modularize BFD a.out a bit.
 460
 461         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 462         * ieee.c:  Cast enums to int before comparing them, for brain-
 463         dead compilers.
 464         * coff-code.h:  Remove coff_get_section_contents, and use the
 465         generic one instead.
 466
 467         * aout.c:  Derive new module from sunos.c, containing generic
 468         support code for all kinds of a.out files.
 469
 470         * sunos.c: Remove all code that goes in aout.c.  Split out
 471         machine dependent followup in sunos4_object_p into
 472         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 473         and redefine only the names we CHANGE, not all the names.  Drop
 474         the little-endian vector, and rename the vector as sunos4 rather
 475         than generic.
 476
 477         * b.out.c:  Use aout.c routines for most of the work.  Slight
 478         changes for the new regime.  Remove close_and_cleanup and
 479         get_section_contents in favor of generics.  New transfer vector
 480         regime.
 481
 482         * newsos.c:  New support for Sony NEWS, another a.out format.
 483
 484         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 485         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 486         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 487         to tvec.
 488         * opncls.c (bfd_close):  Call format-dependent write_contents
 489         routine, if writing, before calling target-dependent
 490         close_and_cleanup routine (which is now always generic, I think).
 491         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 492         close_and_cleanup and move code from it to
 493         srec_write_object_contents.  Add write_contents to tvec.
 494         * targets.c:  Remove a.out little vector, replace a.out big
 495         vector with SunOS vector.  FIXME:  Need Vax support again now.
 496
 497         * libbfd.h:  Add write_contents format-dependent-vector to the
 498         bfd_target vector.  Supply a generic close_and_cleanup routine.
 499         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 500         all routines defined in aout.c.  Rename "sunos" things to "aout"
 501         things.  Add a few fields where needed for various formats.
 502         * Makefile.in:  Add aout.c and newsos.c.
 503
 504         * archive.c, ieee.c, oasys.c:  Lint.
 505
 506 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 507
 508         * ../include/bfd.h
 509         changed forward declaration struct stat; to reduce warnings. Changed
 510         comment on bfd_h_<x>_x.
 511
 512         * ../include/m68kcoff.h, ../include/intel-coff.h,
 513         ../include/m88k-bcs.h
 514         Now there are two incarnations of relocs, linenos and syments. One for
 515         internal digestion, and one full of char arrays for I/O. The original
 516         names have gone to detect errors.
 517
 518         * Makefile.in, m68kcoff.c, targets.c
 519         Test new structure code with a 68k coff implementaion
 520
 521         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 522         Fixed all the places where there were problems with the size and
 523         alignments of structures on disk and structures in memory. #ifed out
 524         all the code in coffswap.c, since it should be done using the target
 525         swap routines now.
 526
 527 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 528
 529         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 530         multiple reloc command.
 531
 532         * sunos.c (sunos4_set_section_contents): Made it so that sections
 533         are always padded to their alignment size.
 534
 535 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 536
 537         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 538         Clean up types and such (saber C problems).
 539         * ecoff.c:  Clean up types and such.  Remove routines that are
 540         not used.  Fix up reading and swapping of shorts from files.
 541
 542    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 543
 544         * a.out.vax.c: Remove two bogus "static" from prototypes.
 545
 546         * ecoff.c: Got rid of lots of non-working junk (that had
 547         been copied directly from coff-code.h).
 548         Updated to be consistent with updates to icoff.c and coff-code.h.
 549
 550         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 551         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 552
 553         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 554         but until the target_vector is automatically generated,
 555         it's as good as any. Note that the text offset is the only
 556         difference between NewsOS and SunOs (including magic numbers).
 557         (Most of the sunos_* routines should to renamed bsd_*
 558         and move to a bsd.c file. Then (and when the target_vector
 559         is automatically generated) it might make sense to create
 560         a separate Sony target.)
 561
 562         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 563         on some systems, and doesn't help on others.
 564         Similarly, only define X_OK if not already defined.
 565
 566         * trad-core.c: Don't include sys/stat.h - at least
 567         on NewsOS 3, it has already been included.
 568
 569 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 570
 571         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 572         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 573         symbol tables if necessary when reading them in, so gdb can use
 574         them.  Add "bfd_coff_" to the names so they won't conflict with
 575         names in calling programs.  FIXME-soon:  if coff-code.h is
 576         included in two BFD modules, this will cause duplicate
 577         definitions; the routines should be exported to a separate,
 578         common, module (probably along with a mess of other ones).
 579
 580 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 581
 582         Improve modtime support.
 583
 584         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 585         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 586         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 587         BUG:  archive members still do not get correct mod times.
 588
 589         Improve floating point support for core files.
 590
 591         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 592         (sunos4_core_file_p):  Create a second registers section in the
 593         core file, called ".reg2", for the float registers.
 594
 595 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 596
 597         * many changes to improve archive handling; found a logic flaw in
 598           bfd_check_format which only just happened to work by cooncidence.
 599
 600 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 601
 602         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 603         correctly.
 604
 605         * bfd.h: changed type of udata in asymbol to void *, like it
 606         should be. Added bfd_reloc_dangerous enum member.
 607
 608         * coff-code.h: Fixed it so that internally generated symbols get
 609         their values relocated correctly in all cases. Removed calls to
 610         xmalloc.
 611
 612         * icoff.c: Not understanding the destination symbol of a reloc is
 613         not a failure any more, just 'dangerous'. This allows linking of
 614         b.out and coff images.
 615
 616         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 617         calculated.
 618
 619
 620 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 621
 622         * sunos.c (translate_to_native_sym_flags): fixed
 623         sym_pointer->n_value so that symbols on the way out get their
 624         section relative values calculated correctly.
 625
 626         * coff-code.h (mangle_symbols): fixed problem where tags were not
 627         being relocated for structs, enums, unions. Also various lints.
 628
 629 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 630
 631         * archive.c (get_elt_at_filepos): system_call_error returned
 632           incorrectly.
 633
 634 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 635
 636         * Resolve the use of no_error and system_call_error.
 637           The bfd library itself now will never set bfd_error to
 638           no_error.
 639
 640           The code still needs to be combed to make sure all the error
 641           codes are correct.  I suspect they are not always set correctly.
 642
 643         * The names of all the messages have _ prepended because the sun
 644           bundled compiler can't distinguish from a macro which takes an
 645           argument and the same identifier in a non-macro context.
 646
 647         * The reason for the above being that entry points which used to
 648           be trampoline functions are now just macros which expand to a
 649           direct call through the bfd's xfer vector.
 650
 651         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 652           must gas have its own version of everything (the gas version
 653           had the correct value)
 654
 655 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 656
 657         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 658         properly support i960 architecture and output correct reloc stuff.
 659
 660         * bfd.h: added prototype for bfd_printable_arch_mach, added
 661         BFD_FAIL
 662
 663         * coff-code.h: Applied patches from chrisb to support i960
 664         architecture, zero relocs and swap them correcly and conditionally
 665         compiled the timestamp.
 666
 667         * sunos.c: Made the default section alignment 2^3 so that doubles
 668         are done properly. Fixed the same reloc bug that was in b.out.c
 669
 670         * sysdep.h: Now compiles on a Posix box
 671
 672 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 673
 674         * icoff.c:  Fix comment on big-endian version.
 675         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 676         F_RELFLG).  Set F_AR32WR in output files if little endian
 677         architecture.
 678
 679 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 680
 681         * archures.c fixed =/== typo
 682
 683         * sunos.c added architecture stuff for output. Fixed
 684         bug where files where vma(data) != size(text)
 685         were processed wrong.
 686
 687         * coff-code.h added a lint cast
 688
 689         * (../include/a.out.sun4.h) fixed it so zmagic
 690         worked
 691
 692 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 693
 694         * archive.c removed loads of includes, and fixed bug where string

 733 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
 734
 735         * bfd.h changed name of alignment entry in sec_struct to
 736         alignment_power, because of conflicting uses within bfd.
 737         Now it should be obvious that it's a 2**n alignment
 738         specifier. Removed start_pad, end_alignment, block, minsize,
 739         output_file_alignment, subsection_alignment and original_vma fields.

 748         Fixed (translate_from_native_sym_flags) to correctly make
 749         symbols section relative.
 750
 751         * bfd.c (bfd_errmsg) fixed various enum cast problems.
 752         (bfd_make_section) took out initialization of obsolete members.

 755         * opncls.c (bfd_create) created.
 756

 758         to obsolete members. (make_a_section_from_file) added
 759         conversion between alignment types. (coff_symbol_from)
 760         added. (coff_count_linenumbers) only counts linenumbers
 761         if symbol is of coff-type. (coff_mangle_symbols) only
 762         heavily mangles symbols if symbol is coff-type.

 775         * bfd.c lots of lint, support for new bfd entry point
 776         bfd_print_symbol.
 777
 778         * bfd.h changed definition of asymbol to contain pointer to
 779         owning bfd, removed target dependencies.
 780
 781         * cache.c took out print statements, put in BFD_ASSERT calls.
 782
 783         * coff-code.h various lints, corrected linenumber output
 784         functionality. Added support for new style asymbols and

 801 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 802
 803         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 804         pointer lint. Added support for callj relocation. Fixed bug where
 805         the last 32 bytes of the text section were overwritten by data. Fixed bug
 806         where archives of b.out didn't work due bfd_slurp_extended_name_table
 807         returning false.
 808
 809         * sunos.c added support for n_other field. Braced the howto table so
 810         that it won't be affected by any lengthing of the howto struct typedef.
 811         Various lints
 812
 813         * bfd.h added support for n_other field, added special_function

 819 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 820
 821         * ChangeLog:  Started ChangeLog for BFD.
 822         * ToDo:  Create file for suggestions.
 823
 824         * Makefile:  Support easy loading into Saber C.
 825         Add dependencies for icoff.o and bcs88kcoff.o.
 826         Rename coff.c to coff-code.h.  Change callers.
 827
 828         * bfd.c (bfd_check_format):  Allow the check_format routines
 829         to return the desired target vector, rather than just a Boolean.
 830         bfd.h (bfd_check_format):  Change function pointer return type.
 831         archive.c (bfd_generic_archive_p):  change callee.
 832         b.out.c (b_out_little_object_p, b_out_big_object_p,
 833         b_out_real_object_p):  change callee.
 834         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 835         in check_format transfer vectors that need a filler.
 836         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 837         bcs88kcoff.c:  change callee.
 838         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 839         icoff.c:  change callee.
 840         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 841
 842         * libbfd.c (zalloc):  It should actually zero the storage!
 843         This was commented out for some reason.
 844
 845         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 846         This is so callers can avoid <stdlib.h> which doesn't exist
 847         on older systems.
 848
 849         * bfd.c (map_over_sections):  Add debugging code, since I
 850         noticed the section count for sunos core files was bad, but only
 851         GDB had detected the problem.
 852         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 853         bfd_get_section_linenos):  Remove obsolete functions.
 854         (bfd_apply_relocations):  Use longs, not ints, for the math.
 855
 856         * bfd.h:  Declare enum boolean and struct bfd_target as well
 857         as typedefs for them.  Remove obsolete
 858         bfd_get_section_lineno_size.
 859
 860         * cache.c:  Make the "fdopen" support work.  Keep better track
 861         of how many files are open.  Centralize the opening of files
 862         and be sure bfd_open[rw] actually try to open the file.  Evade
 863         linked list initialization problems.
 864
 865         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 866
 867         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 868
 869         * cplus-dem.c:  Delete file, since it is not part of BFD.
 870
 871         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 872         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 873
 874         * sunos.c (sunos4_core_file_p):  Set section count.
 875         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 876         obsolete definitions.
 877         (_write_symbol_table):  Initialize <idx> counter.
 878         (foop):  Eliminate debugging code.
