  19         are not defined by the system include files.
  20         (host_aout_{32,64}_write_object_contents):  Use the WRITE_HEADERS
  21         macro used by the other a.out implementations.
  22         * Makefile.in:  Give dependencies to OPTIONAL_BACKENDS.
  23
  24 Wed Aug 21 14:33:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
  25
  26         * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
  27         texdoc and psdoc; make these depend on generated .texi's
  28
  29         * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
  30         doc

  35         * Makefile.in, awkscan-ip, awkscan-p, intobfd,
  36         libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
  37         libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
  38         libbfd.h, and libcoff.h; (b) in generated parts of same, use less
  39         obtrusive marks indicating .c origins.
  40
  41         * bfd.texinfo: generalize most references to linker
  42
  43 Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
  44
  45         * Makefile.in: include core.p in PROTOS (building better bfd.h)

  63
  64 Thu Aug  1 16:35:28 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  65
  66         * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags
  67
  68         * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT

  70         above flags.
  71
  72         * aoutx.h: made translate_from_native_sym_flags and
  73         translate_to_native_sym_flags produce the above flags.
  74
  75
  76 Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
  77
  78         * all files:  update copyright notices for GPL version 2.
  79         Install header comments and attribute most modules to their
  80         authors.  BFD's name is now officially "Binary File Descriptor",
  81         so remove any conflicting pejoratives.
  82         archures.h:  Consists solely of comments; remove it.
  83
  84 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  85
  86         * Makefile.in, bfd.c: Made it compile again.
  87
  88 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  89
  90         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
  91
  92
  93 Mon Jul 15 16:27:42 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  94
  95         * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c

  97         lint fixes.
  98
  99         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
 100         29k coff by David Wood (wood@lab.ultra.nyu.edu).
 101
 102 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 103
 104         * Everything: created some new files, core.c format.c, reloc.c,
 105         section.c and syms.c to split the functionality a bit better.
 106         Cleaned up the rest of the files a bit, and added some
 107         documentation.
 108
 109
 110 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 111
 112         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
 113         really takes 3 arguments, patched code and ammended prototypes.
 114
 115 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 116
 117         * ../include/bfd.h (struct bfd_target): Added new field
 118         "align_power_min" which contains the minimum alignment for a
 119         section. This is used in coff_new_section_hook. The field
 120         insertion necessitates an update of all backends..
 121
 122         * aoutf1.h jump table field inserted
 123
 124         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 125         filenames too.
 126
 127         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 128         table field inserted.
 129
 130         * coffcode.h(just about everything) Now patches up symbol tables
 131         using a different mechanism. The Intel major bug has been fixed,
 132         and the linker can self host on the Aviion and be debugged with
 133         gdb.
 134
 135         * ecoff.c: new include and jump table patch, i386coff.c: new
 136         include and jump table patch,  icoff.c: new include and jump table
 137         patch, ieee.c: can now read archives containing ieee modules.,
 138         libcoff.h: added (combined_entry_type), libieee.h: uped max
 139         sections to 20, m68kcoff.c: new include and jump table patch,
 140         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 141         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
 142         srec.c: jump table patch. trad-code.c fixed #IF typeo
 143
 144 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 145
 146         * coffcode.h (coff_swap_aux_in): added else case to deal with
 147         filenames less than 9 characters.
 148
 149
 150 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 151
 152         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 153
 154         * srec.c: now allows any number of sections to be created in a
 155         file. Outputs addresses of the right length.
 156
 157 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 158
 159         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 160         target didn't match, the format got set to the attempted match,
 161         breaking a future test.
 162
 163         *../include/i386coff.h : fixed typo in type field with size
 164
 165         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 166         support in the jump table for the swapping routines exported to
 167         gdb. Now gdb works with the 386.
 168
 169 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 170
 171         * Merge in changes from gdb-3.95 release.
 172         Makefile.in:  Allow hmake and tmake files to add OFILES.
 173         aoutf1.h:
 174         bfd.c:  support specific targets as well as searching.  When
 175         searching, take default target in preference to others.
 176         bfd.doc:  typos
 177         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 178         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 179         libbfd.h:  Support specific targets as well as searching.
 180         opncls.c:  Support specific targets as well as searching.
 181         targets.c:  Search is short-circuited if default target matches.
 182         liboasys.c, libieee.c:  Undo bothner changes that make macros
 183         work to the left of assignment, but which depend on the
 184         representations of different pointer types being the same.
 185
 186 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 187
 188         * i386coff.c: created.
 189         * coffcode.h: added support for 386.
 190         * Makefile.in: added support for 386.
 191         * ../include/i386coff.h: created
 192
 193 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 194
 195         * coffcode.h: removed all put_x_<sizes>
 196         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 197         DEFUNS
 198
 199
 200 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 201         (bothner)
 202         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 203
 204 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 205
 206         * everything: Removed sysdep.h from bfd.h and put back into files
 207         from which it was split out. Now 64 bit version is built with a
 208         -DHOST_64_BIT="long long" on the compile line.
 209
 210
 211 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 212
 213         Changed all the [get|put][name] routines to use  [get|put]_[size
 214         in bytes].
 215
 216         Put in support for 64 bit work. Now two versions of bfd may be
 217         generated, according to the state of TARGET_64_BIT, one which is
 218         32 bit only, and one which is 64/32 bits.
 219         Created new back end 'demo64' to test 64 bit functionality.
 220
 221         Renamed some files to work on DOS.
 222
 223         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 224         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 225         chage, 64 bit transfer. * liba.out.h: Split out common code from
 226         sunos and newsos into liba.out. Name changes and prototype mods. *
 227         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 228         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 229         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 230         change and 64bit stuff.* newsos3.c: common code removed, new jump
 231         table. * oasys.c: Name change * opncls.c: Portability fixes *
 232         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 233         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 234         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 235         64bit ized. * demo64.c: 64 bit a.out back end
 236
 237
 238
 239
 240
 241 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 242         from bothner
 243         * libieee.h: Make ieee_data and ieee_ar_data macros usable
 244         on LHS of assignment, even when using old compilers.
 245         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 246         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 247         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 248         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 249         * targets.c: Add declaration of newsos3_vec.
 250
 251
 252 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 253
 254         * aout.c: fixxed some of the problems with filepos calculation.
 255         (swap_ext_reloc): fixed problem with creation of relocs.
 256         (aout_set_section_contents): fixed filepos problem
 257
 258         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 259         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 260         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 261         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 262         cleaned up. (coff_write_object_contents) cleaned up.
 263
 264         * ecoff.c: Totally different. Now supports ecoff fully.
 265
 266         * icoff.c: fixed problems in relocation callout.
 267
 268         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 269
 270         * m68kcoff.c: updated target vector.
 271
 272         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 273         choose_reloc_size. (sunos4_write_object_contents) now calls
 274         choose_reloc_size so outputs relocs correctly, also calculates the
 275         size of the sections correctly.
 276
 277
 278
 279 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 280
 281         Merge Per Bothner's changes to modularize BFD a.out a bit.
 282
 283         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 284         * ieee.c:  Cast enums to int before comparing them, for brain-
 285         dead compilers.
 286         * coff-code.h:  Remove coff_get_section_contents, and use the
 287         generic one instead.
 288
 289         * aout.c:  Derive new module from sunos.c, containing generic
 290         support code for all kinds of a.out files.
 291
 292         * sunos.c: Remove all code that goes in aout.c.  Split out
 293         machine dependent followup in sunos4_object_p into
 294         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 295         and redefine only the names we CHANGE, not all the names.  Drop
 296         the little-endian vector, and rename the vector as sunos4 rather
 297         than generic.
 298
 299         * b.out.c:  Use aout.c routines for most of the work.  Slight
 300         changes for the new regime.  Remove close_and_cleanup and
 301         get_section_contents in favor of generics.  New transfer vector
 302         regime.
 303
 304         * newsos.c:  New support for Sony NEWS, another a.out format.
 305
 306         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 307         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 308         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 309         to tvec.
 310         * opncls.c (bfd_close):  Call format-dependent write_contents
 311         routine, if writing, before calling target-dependent
 312         close_and_cleanup routine (which is now always generic, I think).
 313         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 314         close_and_cleanup and move code from it to
 315         srec_write_object_contents.  Add write_contents to tvec.
 316         * targets.c:  Remove a.out little vector, replace a.out big
 317         vector with SunOS vector.  FIXME:  Need Vax support again now.
 318
 319         * libbfd.h:  Add write_contents format-dependent-vector to the
 320         bfd_target vector.  Supply a generic close_and_cleanup routine.
 321         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 322         all routines defined in aout.c.  Rename "sunos" things to "aout"
 323         things.  Add a few fields where needed for various formats.
 324         * Makefile.in:  Add aout.c and newsos.c.
 325
 326         * archive.c, ieee.c, oasys.c:  Lint.
 327
 328 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 329
 330         * ../include/bfd.h
 331         changed forward declaration struct stat; to reduce warnings. Changed
 332         comment on bfd_h_<x>_x.
 333
 334         * ../include/m68kcoff.h, ../include/intel-coff.h,
 335         ../include/m88k-bcs.h
 336         Now there are two incarnations of relocs, linenos and syments. One for
 337         internal digestion, and one full of char arrays for I/O. The original
 338         names have gone to detect errors.
 339
 340         * Makefile.in, m68kcoff.c, targets.c
 341         Test new structure code with a 68k coff implementaion
 342
 343         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 344         Fixed all the places where there were problems with the size and
 345         alignments of structures on disk and structures in memory. #ifed out
 346         all the code in coffswap.c, since it should be done using the target
 347         swap routines now.
 348
 349 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 350
 351         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 352         multiple reloc command.
 353
 354         * sunos.c (sunos4_set_section_contents): Made it so that sections
 355         are always padded to their alignment size.
 356
 357 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 358
 359         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 360         Clean up types and such (saber C problems).
 361         * ecoff.c:  Clean up types and such.  Remove routines that are
 362         not used.  Fix up reading and swapping of shorts from files.
 363
 364    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 365
 366         * a.out.vax.c: Remove two bogus "static" from prototypes.
 367
 368         * ecoff.c: Got rid of lots of non-working junk (that had
 369         been copied directly from coff-code.h).
 370         Updated to be consistent with updates to icoff.c and coff-code.h.
 371
 372         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 373         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 374
 375         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 376         but until the target_vector is automatically generated,
 377         it's as good as any. Note that the text offset is the only
 378         difference between NewsOS and SunOs (including magic numbers).
 379         (Most of the sunos_* routines should to renamed bsd_*
 380         and move to a bsd.c file. Then (and when the target_vector
 381         is automatically generated) it might make sense to create
 382         a separate Sony target.)
 383
 384         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 385         on some systems, and doesn't help on others.
 386         Similarly, only define X_OK if not already defined.
 387
 388         * trad-core.c: Don't include sys/stat.h - at least
 389         on NewsOS 3, it has already been included.
 390
 391 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 392
 393         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 394         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 395         symbol tables if necessary when reading them in, so gdb can use
 396         them.  Add "bfd_coff_" to the names so they won't conflict with
 397         names in calling programs.  FIXME-soon:  if coff-code.h is
 398         included in two BFD modules, this will cause duplicate
 399         definitions; the routines should be exported to a separate,
 400         common, module (probably along with a mess of other ones).
 401
 402 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 403
 404         Improve modtime support.
 405
 406         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 407         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 408         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 409         BUG:  archive members still do not get correct mod times.
 410
 411         Improve floating point support for core files.
 412
 413         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 414         (sunos4_core_file_p):  Create a second registers section in the
 415         core file, called ".reg2", for the float registers.
 416
 417 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 418
 419         * many changes to improve archive handling; found a logic flaw in
 420           bfd_check_format which only just happened to work by cooncidence.
 421
 422 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 423
 424         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 425         correctly.
 426
 427         * bfd.h: changed type of udata in asymbol to void *, like it
 428         should be. Added bfd_reloc_dangerous enum member.
 429
 430         * coff-code.h: Fixed it so that internally generated symbols get
 431         their values relocated correctly in all cases. Removed calls to
 432         xmalloc.
 433
 434         * icoff.c: Not understanding the destination symbol of a reloc is
 435         not a failure any more, just 'dangerous'. This allows linking of
 436         b.out and coff images.
 437
 438         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 439         calculated.
 440
 441
 442 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 443
 444         * sunos.c (translate_to_native_sym_flags): fixed
 445         sym_pointer->n_value so that symbols on the way out get their
 446         section relative values calculated correctly.
 447
 448         * coff-code.h (mangle_symbols): fixed problem where tags were not
 449         being relocated for structs, enums, unions. Also various lints.
 450
 451 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 452
 453         * archive.c (get_elt_at_filepos): system_call_error returned
 454           incorrectly.
 455
 456 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 457
 458         * Resolve the use of no_error and system_call_error.
 459           The bfd library itself now will never set bfd_error to
 460           no_error.
 461
 462           The code still needs to be combed to make sure all the error
 463           codes are correct.  I suspect they are not always set correctly.
 464
 465         * The names of all the messages have _ prepended because the sun
 466           bundled compiler can't distinguish from a macro which takes an
 467           argument and the same identifier in a non-macro context.
 468
 469         * The reason for the above being that entry points which used to
 470           be trampoline functions are now just macros which expand to a
 471           direct call through the bfd's xfer vector.
 472
 473         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 474           must gas have its own version of everything (the gas version
 475           had the correct value)
 476
 477 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 478
 479         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 480         properly support i960 architecture and output correct reloc stuff.
 481
 482         * bfd.h: added prototype for bfd_printable_arch_mach, added
 483         BFD_FAIL
 484
 485         * coff-code.h: Applied patches from chrisb to support i960
 486         architecture, zero relocs and swap them correcly and conditionally
 487         compiled the timestamp.
 488
 489         * sunos.c: Made the default section alignment 2^3 so that doubles
 490         are done properly. Fixed the same reloc bug that was in b.out.c
 491
 492         * sysdep.h: Now compiles on a Posix box
 493
 494 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 495
 496         * icoff.c:  Fix comment on big-endian version.
 497         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 498         F_RELFLG).  Set F_AR32WR in output files if little endian
 499         architecture.
 500
 501 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 502
 503         * archures.c fixed =/== typo
 504
 505         * sunos.c added architecture stuff for output. Fixed
 506         bug where files where vma(data) != size(text)
 507         were processed wrong.
 508
 509         * coff-code.h added a lint cast
 510
 511         * (../include/a.out.sun4.h) fixed it so zmagic
 512         worked
 513
 514 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 515
 516         * archive.c removed loads of includes, and fixed bug where string
 517         table didn't have a null at the end.
 518
 519         * bfd.c fixed includes, added symbols argument to
 520         canonicalize_reloc entry point.
 521
 522         * libbfd.c fixed includes and added some lint patches.
 523
 524         * targets.c added both sorts of intel coff.
 525
 526         * b.out.c fixed included, changed was the canonical
 527         relocs were done.
 528
 529         * icoff.c added support for callj and big and little
 530         enidian tables.
 531
 532         * opncls.c added chmod+xing for files with EXEC_P set.
 533
 534         * sunos.c fixed includes. Changed default section
 535         alignement to words. Fixed relocation stuff to work with
 536         new scheme
 537
 538         * bfd.h various new types added, prototype for new
 539         reloc calls, changed bfd->iostream to a void *
 540         to including files don't need stdio.h.
 541
 542         * libcoff.h added conversion table to tie relocs to
 543         canonical symbols
 544
 545         * sysdep.h created
 546
 547         * coff-code.h fixed includes. Added code to support
 548         big and little endian formats. Various lints. Better
 549         processing of symbols. Changed reloc stuff to new
 550         order
 551
 552         * libbfd.h fixed includes
 553
 554
 555 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
 556
 557         * bfd.h changed name of alignment entry in sec_struct to
 558         alignment_power, because of conflicting uses within bfd.
 559         Now it should be obvious that it's a 2**n alignment
 560         specifier. Removed start_pad, end_alignment, block, minsize,
 561         output_file_alignment, subsection_alignment and original_vma fields.
 562         Added align_power() macro. Fixed bfd_section_alignment
 563         acessor macros. Added bfd_symbol_same_target macro.
 564
 565         * b.out.c (b_out_write_object_contents) fixed to use
 566         new alignment member. Fixed (callj_callback) to use section
 567         relative symbols properly.
 568
 569         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 570         Fixed (translate_from_native_sym_flags) to correctly make
 571         symbols section relative.
 572
 573         * bfd.c (bfd_errmsg) fixed various enum cast problems.
 574         (bfd_make_section) took out initialization of obsolete members.
 575         (bfd_print_symbol_vandf) added
 576
 577         * opncls.c (bfd_create) created.
 578
 579         * coff-code.h (coff_new_section_hook) took away refs
 580         to obsolete members. (make_a_section_from_file) added
 581         conversion between alignment types. (coff_symbol_from)
 582         added. (coff_count_linenumbers) only counts linenumbers
 583         if symbol is of coff-type. (coff_mangle_symbols) only
 584         heavily mangles symbols if symbol is coff-type.
 585         (coff_write_symbols) various lints. (coff_write_object_contents)
 586         various lints and modification for alignment conversion.
 587         (coff_slurp_relocs) fixed for use with new asection shape.
 588
 589 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
 590
 591         * archive.c lots of lint
 592
 593         * b.out.c added callj relocation support, upgrated reloc howto.
 594         Fixed so that asymbol and reloc records are output
 595         correctly.
 596
 597         * bfd.c lots of lint, support for new bfd entry point
 598         bfd_print_symbol.
 599
 600         * bfd.h changed definition of asymbol to contain pointer to
 601         owning bfd, removed target dependencies.
 602
 603         * cache.c took out print statements, put in BFD_ASSERT calls.
 604
 605         * coff-code.h various lints, corrected linenumber output
 606         functionality. Added support for new style asymbols and
 607         bfd_print_symbol. Fixed so that asymbol and
 608         reloc records are handled correctly. Added timestamp.
 609
 610         * icoff.c Added support for new howto shape.
 611
 612         * liba.out.h Added support for new asymbol shape
 613
 614         * libbfd.c various lints
 615
 616         * libbfd.h various lints
 617
 618         * libcoff.h added support for new asymbol shape.
 619
 620         * sunos.c  various lints. Added support for new asymbol shape
 621         and bfd_print_symbol.
 622
 623 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 624
 625         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 626         pointer lint. Added support for callj relocation. Fixed bug where
 627         the last 32 bytes of the text section were overwritten by data. Fixed bug
 628         where archives of b.out didn't work due bfd_slurp_extended_name_table
 629         returning false.
 630
 631         * sunos.c added support for n_other field. Braced the howto table so
 632         that it won't be affected by any lengthing of the howto struct typedef.
 633         Various lints
 634
 635         * bfd.h added support for n_other field, added special_function
 636         reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
 637         macros.
 638
 639         * bfd.c upgraded bfd_perform_relocation, various lints.
 640
 641 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 642
 643         * ChangeLog:  Started ChangeLog for BFD.
 644         * ToDo:  Create file for suggestions.
 645
 646         * Makefile:  Support easy loading into Saber C.
 647         Add dependencies for icoff.o and bcs88kcoff.o.
 648         Rename coff.c to coff-code.h.  Change callers.
 649
 650         * bfd.c (bfd_check_format):  Allow the check_format routines
 651         to return the desired target vector, rather than just a Boolean.
 652         bfd.h (bfd_check_format):  Change function pointer return type.
 653         archive.c (bfd_generic_archive_p):  change callee.
 654         b.out.c (b_out_little_object_p, b_out_big_object_p,
 655         b_out_real_object_p):  change callee.
 656         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 657         in check_format transfer vectors that need a filler.
 658         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 659         bcs88kcoff.c:  change callee.
 660         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 661         icoff.c:  change callee.
 662         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 663
 664         * libbfd.c (zalloc):  It should actually zero the storage!
 665         This was commented out for some reason.
 666
 667         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 668         This is so callers can avoid <stdlib.h> which doesn't exist
 669         on older systems.
 670
 671         * bfd.c (map_over_sections):  Add debugging code, since I
 672         noticed the section count for sunos core files was bad, but only
 673         GDB had detected the problem.
 674         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 675         bfd_get_section_linenos):  Remove obsolete functions.
 676         (bfd_apply_relocations):  Use longs, not ints, for the math.
 677
 678         * bfd.h:  Declare enum boolean and struct bfd_target as well
 679         as typedefs for them.  Remove obsolete
 680         bfd_get_section_lineno_size.
 681
 682         * cache.c:  Make the "fdopen" support work.  Keep better track
 683         of how many files are open.  Centralize the opening of files
 684         and be sure bfd_open[rw] actually try to open the file.  Evade
 685         linked list initialization problems.
 686
 687         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 688
 689         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 690
 691         * cplus-dem.c:  Delete file, since it is not part of BFD.
 692
 693         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 694         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 695
 696         * sunos.c (sunos4_core_file_p):  Set section count.
 697         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 698         obsolete definitions.
 699         (_write_symbol_table):  Initialize <idx> counter.
 700         (foop):  Eliminate debugging code.
 701
 702
 703
 704
