 121         authors.  BFD's name is now officially "Binary File Descriptor",
 122         so remove any conflicting pejoratives.
 123         archures.h:  Consists solely of comments; remove it.
 124
 125 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 126
 127         * Makefile.in, bfd.c: Made it compile again.

 144
 145         * Everything: created some new files, core.c format.c, reloc.c,
 146         section.c and syms.c to split the functionality a bit better.

 149
 150
 151 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 152

 157
 158         * ../include/bfd.h (struct bfd_target): Added new field
 159         "align_power_min" which contains the minimum alignment for a
 160         section. This is used in coff_new_section_hook. The field
 161         insertion necessitates an update of all backends..
 162
 163         * aoutf1.h jump table field inserted
 164
 165         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 166         filenames too.
 167
 168         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 169         table field inserted.
 170
 171         * coffcode.h(just about everything) Now patches up symbol tables
 172         using a different mechanism. The Intel major bug has been fixed,
 173         and the linker can self host on the Aviion and be debugged with
 174         gdb.
 175
 176         * ecoff.c: new include and jump table patch, i386coff.c: new
 177         include and jump table patch,  icoff.c: new include and jump table
 178         patch, ieee.c: can now read archives containing ieee modules.,

 180         sections to 20, m68kcoff.c: new include and jump table patch,
 181         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 182         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
 183         srec.c: jump table patch. trad-code.c fixed #IF typeo
 184
 185 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 186
 187         * coffcode.h (coff_swap_aux_in): added else case to deal with
 188         filenames less than 9 characters.
 189
 190
 191 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 192
 193         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 194
 195         * srec.c: now allows any number of sections to be created in a
 196         file. Outputs addresses of the right length.
 197
 198 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 199
 200         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 201         target didn't match, the format got set to the attempted match,
 202         breaking a future test.
 203
 204         *../include/i386coff.h : fixed typo in type field with size
 205
 206         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 207         support in the jump table for the swapping routines exported to
 208         gdb. Now gdb works with the 386.
 209
 210 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 211
 212         * Merge in changes from gdb-3.95 release.
 213         Makefile.in:  Allow hmake and tmake files to add OFILES.
 214         aoutf1.h:
 215         bfd.c:  support specific targets as well as searching.  When
 216         searching, take default target in preference to others.
 217         bfd.doc:  typos
 218         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 219         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 220         libbfd.h:  Support specific targets as well as searching.
 221         opncls.c:  Support specific targets as well as searching.
 222         targets.c:  Search is short-circuited if default target matches.
 223         liboasys.c, libieee.c:  Undo bothner changes that make macros
 224         work to the left of assignment, but which depend on the
 225         representations of different pointer types being the same.
 226
 227 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 228
 229         * i386coff.c: created.
 230         * coffcode.h: added support for 386.
 231         * Makefile.in: added support for 386.
 232         * ../include/i386coff.h: created
 233
 234 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

 237         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 238         DEFUNS
 239
 240
 241 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 242         (bothner)
 243         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 244
 245 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 246
 247         * everything: Removed sysdep.h from bfd.h and put back into files
 248         from which it was split out. Now 64 bit version is built with a
 249         -DHOST_64_BIT="long long" on the compile line.
 250
 251
 252 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 253
 254         Changed all the [get|put][name] routines to use  [get|put]_[size
 255         in bytes].
 256
 257         Put in support for 64 bit work. Now two versions of bfd may be
 258         generated, according to the state of TARGET_64_BIT, one which is
 259         32 bit only, and one which is 64/32 bits.
 260         Created new back end 'demo64' to test 64 bit functionality.

 269         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 270         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 271         change and 64bit stuff.* newsos3.c: common code removed, new jump
 272         table. * oasys.c: Name change * opncls.c: Portability fixes *
 273         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 274         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 275         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 276         64bit ized. * demo64.c: 64 bit a.out back end
 277

 281
 282 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 283         from bothner

 285         on LHS of assignment, even when using old compilers.
 286         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 287         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 288         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 289         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 290         * targets.c: Add declaration of newsos3_vec.
 291
 292
 293 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 294
 295         * aout.c: fixxed some of the problems with filepos calculation.
 296         (swap_ext_reloc): fixed problem with creation of relocs.
 297         (aout_set_section_contents): fixed filepos problem
 298
 299         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 300         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 301         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 302         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 303         cleaned up. (coff_write_object_contents) cleaned up.
 304
 305         * ecoff.c: Totally different. Now supports ecoff fully.
 306
 307         * icoff.c: fixed problems in relocation callout.
 308
 309         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 310
 311         * m68kcoff.c: updated target vector.
 312
 313         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 314         choose_reloc_size. (sunos4_write_object_contents) now calls
 315         choose_reloc_size so outputs relocs correctly, also calculates the
 316         size of the sections correctly.
 317

 319
 320 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 321
 322         Merge Per Bothner's changes to modularize BFD a.out a bit.
 323
 324         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 325         * ieee.c:  Cast enums to int before comparing them, for brain-
 326         dead compilers.
 327         * coff-code.h:  Remove coff_get_section_contents, and use the
 328         generic one instead.
 329
 330         * aout.c:  Derive new module from sunos.c, containing generic
 331         support code for all kinds of a.out files.
 332
 333         * sunos.c: Remove all code that goes in aout.c.  Split out
 334         machine dependent followup in sunos4_object_p into
 335         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 336         and redefine only the names we CHANGE, not all the names.  Drop
 337         the little-endian vector, and rename the vector as sunos4 rather
 338         than generic.
 339
 340         * b.out.c:  Use aout.c routines for most of the work.  Slight
 341         changes for the new regime.  Remove close_and_cleanup and
 342         get_section_contents in favor of generics.  New transfer vector
 343         regime.
 344
 345         * newsos.c:  New support for Sony NEWS, another a.out format.
 346
 347         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 348         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 349         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 350         to tvec.
 351         * opncls.c (bfd_close):  Call format-dependent write_contents
 352         routine, if writing, before calling target-dependent
 353         close_and_cleanup routine (which is now always generic, I think).
 354         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 355         close_and_cleanup and move code from it to
 356         srec_write_object_contents.  Add write_contents to tvec.
 357         * targets.c:  Remove a.out little vector, replace a.out big
 358         vector with SunOS vector.  FIXME:  Need Vax support again now.
 359
 360         * libbfd.h:  Add write_contents format-dependent-vector to the
 361         bfd_target vector.  Supply a generic close_and_cleanup routine.
 362         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 363         all routines defined in aout.c.  Rename "sunos" things to "aout"
 364         things.  Add a few fields where needed for various formats.
 365         * Makefile.in:  Add aout.c and newsos.c.
 366
 367         * archive.c, ieee.c, oasys.c:  Lint.
 368
 369 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 370
 371         * ../include/bfd.h
 372         changed forward declaration struct stat; to reduce warnings. Changed
 373         comment on bfd_h_<x>_x.
 374
 375         * ../include/m68kcoff.h, ../include/intel-coff.h,
 376         ../include/m88k-bcs.h
 377         Now there are two incarnations of relocs, linenos and syments. One for
 378         internal digestion, and one full of char arrays for I/O. The original
 379         names have gone to detect errors.
 380
 381         * Makefile.in, m68kcoff.c, targets.c
 382         Test new structure code with a 68k coff implementaion
 383
 384         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 385         Fixed all the places where there were problems with the size and
 386         alignments of structures on disk and structures in memory. #ifed out
 387         all the code in coffswap.c, since it should be done using the target
 388         swap routines now.
 389
 390 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 391
 392         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 393         multiple reloc command.
 394
 395         * sunos.c (sunos4_set_section_contents): Made it so that sections
 396         are always padded to their alignment size.
 397
 398 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 399
 400         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 401         Clean up types and such (saber C problems).
 402         * ecoff.c:  Clean up types and such.  Remove routines that are
 403         not used.  Fix up reading and swapping of shorts from files.
 404
 405    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 406
 407         * a.out.vax.c: Remove two bogus "static" from prototypes.
 408
 409         * ecoff.c: Got rid of lots of non-working junk (that had
 410         been copied directly from coff-code.h).
 411         Updated to be consistent with updates to icoff.c and coff-code.h.
 412
 413         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 414         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 415
 416         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 417         but until the target_vector is automatically generated,
 418         it's as good as any. Note that the text offset is the only
 419         difference between NewsOS and SunOs (including magic numbers).
 420         (Most of the sunos_* routines should to renamed bsd_*
 421         and move to a bsd.c file. Then (and when the target_vector
 422         is automatically generated) it might make sense to create
 423         a separate Sony target.)
 424
 425         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 426         on some systems, and doesn't help on others.
 427         Similarly, only define X_OK if not already defined.
 428
 429         * trad-core.c: Don't include sys/stat.h - at least
 430         on NewsOS 3, it has already been included.
 431
 432 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 433
 434         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 435         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 436         symbol tables if necessary when reading them in, so gdb can use
 437         them.  Add "bfd_coff_" to the names so they won't conflict with
 438         names in calling programs.  FIXME-soon:  if coff-code.h is
 439         included in two BFD modules, this will cause duplicate
 440         definitions; the routines should be exported to a separate,
 441         common, module (probably along with a mess of other ones).
 442
 443 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 444
 445         Improve modtime support.
 446
 447         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 448         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 449         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 450         BUG:  archive members still do not get correct mod times.
 451
 452         Improve floating point support for core files.
 453
 454         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 455         (sunos4_core_file_p):  Create a second registers section in the
 456         core file, called ".reg2", for the float registers.
 457
 458 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 459
 460         * many changes to improve archive handling; found a logic flaw in
 461           bfd_check_format which only just happened to work by cooncidence.
 462
 463 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 464
 465         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 466         correctly.
 467
 468         * bfd.h: changed type of udata in asymbol to void *, like it
 469         should be. Added bfd_reloc_dangerous enum member.
 470
 471         * coff-code.h: Fixed it so that internally generated symbols get
 472         their values relocated correctly in all cases. Removed calls to
 473         xmalloc.
 474
 475         * icoff.c: Not understanding the destination symbol of a reloc is
 476         not a failure any more, just 'dangerous'. This allows linking of
 477         b.out and coff images.
 478
 479         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 480         calculated.
 481
 482
 483 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 484
 485         * sunos.c (translate_to_native_sym_flags): fixed
 486         sym_pointer->n_value so that symbols on the way out get their
 487         section relative values calculated correctly.
 488
 489         * coff-code.h (mangle_symbols): fixed problem where tags were not
 490         being relocated for structs, enums, unions. Also various lints.
 491
 492 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 493
 494         * archive.c (get_elt_at_filepos): system_call_error returned
 495           incorrectly.
 496
 497 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 498
 499         * Resolve the use of no_error and system_call_error.
 500           The bfd library itself now will never set bfd_error to
 501           no_error.
 502
 503           The code still needs to be combed to make sure all the error
 504           codes are correct.  I suspect they are not always set correctly.
 505
 506         * The names of all the messages have _ prepended because the sun
 507           bundled compiler can't distinguish from a macro which takes an
 508           argument and the same identifier in a non-macro context.
 509
 510         * The reason for the above being that entry points which used to
 511           be trampoline functions are now just macros which expand to a
 512           direct call through the bfd's xfer vector.
 513
 514         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 515           must gas have its own version of everything (the gas version
 516           had the correct value)
 517
 518 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 519
 520         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 521         properly support i960 architecture and output correct reloc stuff.
 522
 523         * bfd.h: added prototype for bfd_printable_arch_mach, added
 524         BFD_FAIL
 525
 526         * coff-code.h: Applied patches from chrisb to support i960
 527         architecture, zero relocs and swap them correcly and conditionally
 528         compiled the timestamp.
 529
 530         * sunos.c: Made the default section alignment 2^3 so that doubles
 531         are done properly. Fixed the same reloc bug that was in b.out.c
 532
 533         * sysdep.h: Now compiles on a Posix box
 534
 535 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 536
 537         * icoff.c:  Fix comment on big-endian version.
 538         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 539         F_RELFLG).  Set F_AR32WR in output files if little endian
 540         architecture.
 541
 542 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 543
 544         * archures.c fixed =/== typo
 545
 546         * sunos.c added architecture stuff for output. Fixed
 547         bug where files where vma(data) != size(text)
 548         were processed wrong.
 549
 550         * coff-code.h added a lint cast
 551
 552         * (../include/a.out.sun4.h) fixed it so zmagic
 553         worked
 554
 555 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 556
 557         * archive.c removed loads of includes, and fixed bug where string
 558         table didn't have a null at the end.
 559
 560         * bfd.c fixed includes, added symbols argument to
 561         canonicalize_reloc entry point.
 562
 563         * libbfd.c fixed includes and added some lint patches.
 564
 565         * targets.c added both sorts of intel coff.
 566
 567         * b.out.c fixed included, changed was the canonical
 568         relocs were done.
 569
 570         * icoff.c added support for callj and big and little
 571         enidian tables.
 572
 573         * opncls.c added chmod+xing for files with EXEC_P set.
 574
 575         * sunos.c fixed includes. Changed default section
 576         alignement to words. Fixed relocation stuff to work with
 577         new scheme
 578
 579         * bfd.h various new types added, prototype for new
 580         reloc calls, changed bfd->iostream to a void *
 581         to including files don't need stdio.h.
 582
 583         * libcoff.h added conversion table to tie relocs to
 584         canonical symbols
 585
 586         * sysdep.h created
 587
 588         * coff-code.h fixed includes. Added code to support
 589         big and little endian formats. Various lints. Better
 590         processing of symbols. Changed reloc stuff to new
 591         order
 592
 593         * libbfd.h fixed includes
 594
 595
 596 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
 597
 598         * bfd.h changed name of alignment entry in sec_struct to
 599         alignment_power, because of conflicting uses within bfd.
 600         Now it should be obvious that it's a 2**n alignment
 601         specifier. Removed start_pad, end_alignment, block, minsize,
 602         output_file_alignment, subsection_alignment and original_vma fields.
 603         Added align_power() macro. Fixed bfd_section_alignment
 604         acessor macros. Added bfd_symbol_same_target macro.
 605
 606         * b.out.c (b_out_write_object_contents) fixed to use
 607         new alignment member. Fixed (callj_callback) to use section
 608         relative symbols properly.
 609
 610         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 611         Fixed (translate_from_native_sym_flags) to correctly make
 612         symbols section relative.
 613
 614         * bfd.c (bfd_errmsg) fixed various enum cast problems.
 615         (bfd_make_section) took out initialization of obsolete members.
 616         (bfd_print_symbol_vandf) added
 617
 618         * opncls.c (bfd_create) created.
 619
 620         * coff-code.h (coff_new_section_hook) took away refs
 621         to obsolete members. (make_a_section_from_file) added
 622         conversion between alignment types. (coff_symbol_from)
 623         added. (coff_count_linenumbers) only counts linenumbers
 624         if symbol is of coff-type. (coff_mangle_symbols) only
 625         heavily mangles symbols if symbol is coff-type.
 626         (coff_write_symbols) various lints. (coff_write_object_contents)
 627         various lints and modification for alignment conversion.
 628         (coff_slurp_relocs) fixed for use with new asection shape.
 629
 630 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
 631
 632         * archive.c lots of lint
 633
 634         * b.out.c added callj relocation support, upgrated reloc howto.
 635         Fixed so that asymbol and reloc records are output
 636         correctly.
 637
 638         * bfd.c lots of lint, support for new bfd entry point
 639         bfd_print_symbol.
 640
 641         * bfd.h changed definition of asymbol to contain pointer to
 642         owning bfd, removed target dependencies.
 643
 644         * cache.c took out print statements, put in BFD_ASSERT calls.
 645
 646         * coff-code.h various lints, corrected linenumber output
 647         functionality. Added support for new style asymbols and
 648         bfd_print_symbol. Fixed so that asymbol and
 649         reloc records are handled correctly. Added timestamp.
 650
 651         * icoff.c Added support for new howto shape.
 652
 653         * liba.out.h Added support for new asymbol shape
 654
 655         * libbfd.c various lints
 656
 657         * libbfd.h various lints
 658
 659         * libcoff.h added support for new asymbol shape.
 660
 661         * sunos.c  various lints. Added support for new asymbol shape
 662         and bfd_print_symbol.
 663
 664 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 665
 666         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 667         pointer lint. Added support for callj relocation. Fixed bug where
 668         the last 32 bytes of the text section were overwritten by data. Fixed bug
 669         where archives of b.out didn't work due bfd_slurp_extended_name_table
 670         returning false.
 671
 672         * sunos.c added support for n_other field. Braced the howto table so
 673         that it won't be affected by any lengthing of the howto struct typedef.
 674         Various lints
 675
 676         * bfd.h added support for n_other field, added special_function
 677         reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
 678         macros.
 679
 680         * bfd.c upgraded bfd_perform_relocation, various lints.
 681
 682 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 683
 684         * ChangeLog:  Started ChangeLog for BFD.
 685         * ToDo:  Create file for suggestions.
 686
 687         * Makefile:  Support easy loading into Saber C.
 688         Add dependencies for icoff.o and bcs88kcoff.o.
 689         Rename coff.c to coff-code.h.  Change callers.
 690
 691         * bfd.c (bfd_check_format):  Allow the check_format routines
 692         to return the desired target vector, rather than just a Boolean.
 693         bfd.h (bfd_check_format):  Change function pointer return type.
 694         archive.c (bfd_generic_archive_p):  change callee.
 695         b.out.c (b_out_little_object_p, b_out_big_object_p,
 696         b_out_real_object_p):  change callee.
 697         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 698         in check_format transfer vectors that need a filler.
 699         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 700         bcs88kcoff.c:  change callee.
 701         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 702         icoff.c:  change callee.
 703         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 704
 705         * libbfd.c (zalloc):  It should actually zero the storage!
 706         This was commented out for some reason.
 707
 708         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 709         This is so callers can avoid <stdlib.h> which doesn't exist
 710         on older systems.
 711
 712         * bfd.c (map_over_sections):  Add debugging code, since I
 713         noticed the section count for sunos core files was bad, but only
 714         GDB had detected the problem.
 715         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 716         bfd_get_section_linenos):  Remove obsolete functions.
 717         (bfd_apply_relocations):  Use longs, not ints, for the math.
 718
 719         * bfd.h:  Declare enum boolean and struct bfd_target as well
 720         as typedefs for them.  Remove obsolete
 721         bfd_get_section_lineno_size.
 722
 723         * cache.c:  Make the "fdopen" support work.  Keep better track
 724         of how many files are open.  Centralize the opening of files
 725         and be sure bfd_open[rw] actually try to open the file.  Evade
 726         linked list initialization problems.
 727
 728         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 729
 730         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 731
 732         * cplus-dem.c:  Delete file, since it is not part of BFD.
 733
 734         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 735         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 736
 737         * sunos.c (sunos4_core_file_p):  Set section count.
 738         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 739         obsolete definitions.
 740         (_write_symbol_table):  Initialize <idx> counter.
 741         (foop):  Eliminate debugging code.
