   1 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
   2
   3         * Makefile.in, bfd.c: Made it compile again.
   4
   5 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
   6
   7         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
   8
   9
  10 Mon Jul 15 16:27:42 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  11
  12         * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c
  13         bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on
  14         lint fixes.
  15
  16         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
  17         29k coff by David Wood (wood@lab.ultra.nyu.edu).
  18
  19 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  20
  21         * Everything: created some new files, core.c format.c, reloc.c,
  22         section.c and syms.c to split the functionality a bit better.
  23         Cleaned up the rest of the files a bit, and added some
  24         documentation.
  25
  26
  27 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
  28
  29         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
  30         really takes 3 arguments, patched code and ammended prototypes.
  31
  32 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  33
  34         * ../include/bfd.h (struct bfd_target): Added new field
  35         "align_power_min" which contains the minimum alignment for a
  36         section. This is used in coff_new_section_hook. The field
  37         insertion necessitates an update of all backends..
  38
  39         * aoutf1.h jump table field inserted
  40
  41         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
  42         filenames too.
  43
  44         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
  45         table field inserted.
  46
  47         * coffcode.h(just about everything) Now patches up symbol tables
  48         using a different mechanism. The Intel major bug has been fixed,
  49         and the linker can self host on the Aviion and be debugged with
  50         gdb.
  51
  52         * ecoff.c: new include and jump table patch, i386coff.c: new
  53         include and jump table patch,  icoff.c: new include and jump table
  54         patch, ieee.c: can now read archives containing ieee modules.,
  55         libcoff.h: added (combined_entry_type), libieee.h: uped max
  56         sections to 20, m68kcoff.c: new include and jump table patch,
  57         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
  58         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
  59         srec.c: jump table patch. trad-code.c fixed #IF typeo
  60
  61 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
  62
  63         * coffcode.h (coff_swap_aux_in): added else case to deal with
  64         filenames less than 9 characters.
  65
  66
  67 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  68
  69         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
  70
  71         * srec.c: now allows any number of sections to be created in a
  72         file. Outputs addresses of the right length.
  73
  74 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  75
  76         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
  77         target didn't match, the format got set to the attempted match,
  78         breaking a future test.
  79
  80         *../include/i386coff.h : fixed typo in type field with size
  81
  82         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
  83         support in the jump table for the swapping routines exported to
  84         gdb. Now gdb works with the 386.
  85
  86 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
  87
  88         * Merge in changes from gdb-3.95 release.
  89         Makefile.in:  Allow hmake and tmake files to add OFILES.
  90         aoutf1.h:
  91         bfd.c:  support specific targets as well as searching.  When
  92         searching, take default target in preference to others.
  93         bfd.doc:  typos
  94         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
  95         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
  96         libbfd.h:  Support specific targets as well as searching.
  97         opncls.c:  Support specific targets as well as searching.
  98         targets.c:  Search is short-circuited if default target matches.
  99         liboasys.c, libieee.c:  Undo bothner changes that make macros
 100         work to the left of assignment, but which depend on the
 101         representations of different pointer types being the same.
 102
 103 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 104
 105         * i386coff.c: created.
 106         * coffcode.h: added support for 386.
 107         * Makefile.in: added support for 386.
 108         * ../include/i386coff.h: created
 109
 110 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 111
 112         * coffcode.h: removed all put_x_<sizes>
 113         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 114         DEFUNS
 115
 116
 117 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 118         (bothner)
 119         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 120
 121 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 122
 123         * everything: Removed sysdep.h from bfd.h and put back into files
 124         from which it was split out. Now 64 bit version is built with a
 125         -DHOST_64_BIT="long long" on the compile line.
 126
 127
 128 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 129
 130         Changed all the [get|put][name] routines to use  [get|put]_[size
 131         in bytes].
 132
 133         Put in support for 64 bit work. Now two versions of bfd may be
 134         generated, according to the state of TARGET_64_BIT, one which is
 135         32 bit only, and one which is 64/32 bits.
 136         Created new back end 'demo64' to test 64 bit functionality.
 137
 138         Renamed some files to work on DOS.
 139
 140         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 141         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 142         chage, 64 bit transfer. * liba.out.h: Split out common code from
 143         sunos and newsos into liba.out. Name changes and prototype mods. *
 144         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 145         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 146         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 147         change and 64bit stuff.* newsos3.c: common code removed, new jump
 148         table. * oasys.c: Name change * opncls.c: Portability fixes *
 149         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 150         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 151         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 152         64bit ized. * demo64.c: 64 bit a.out back end
 153
 154
 155
 156
 157
 158 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 159         from bothner
 160         * libieee.h: Make ieee_data and ieee_ar_data macros usable
 161         on LHS of assignment, even when using old compilers.
 162         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 163         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 164         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 165         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 166         * targets.c: Add declaration of newsos3_vec.
 167
 168
 169 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 170
 171         * aout.c: fixxed some of the problems with filepos calculation.
 172         (swap_ext_reloc): fixed problem with creation of relocs.
 173         (aout_set_section_contents): fixed filepos problem
 174
 175         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 176         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 177         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 178         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 179         cleaned up. (coff_write_object_contents) cleaned up.
 180
 181         * ecoff.c: Totally different. Now supports ecoff fully.
 182
 183         * icoff.c: fixed problems in relocation callout.
 184
 185         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 186
 187         * m68kcoff.c: updated target vector.
 188
 189         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 190         choose_reloc_size. (sunos4_write_object_contents) now calls
 191         choose_reloc_size so outputs relocs correctly, also calculates the
 192         size of the sections correctly.
 193
 194
 195
 196 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 197
 198         Merge Per Bothner's changes to modularize BFD a.out a bit.
 199
 200         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 201         * ieee.c:  Cast enums to int before comparing them, for brain-
 202         dead compilers.
 203         * coff-code.h:  Remove coff_get_section_contents, and use the
 204         generic one instead.
 205
 206         * aout.c:  Derive new module from sunos.c, containing generic
 207         support code for all kinds of a.out files.
 208
 209         * sunos.c: Remove all code that goes in aout.c.  Split out
 210         machine dependent followup in sunos4_object_p into
 211         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 212         and redefine only the names we CHANGE, not all the names.  Drop
 213         the little-endian vector, and rename the vector as sunos4 rather
 214         than generic.
 215
 216         * b.out.c:  Use aout.c routines for most of the work.  Slight
 217         changes for the new regime.  Remove close_and_cleanup and
 218         get_section_contents in favor of generics.  New transfer vector
 219         regime.
 220
 221         * newsos.c:  New support for Sony NEWS, another a.out format.
 222
 223         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 224         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 225         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 226         to tvec.
 227         * opncls.c (bfd_close):  Call format-dependent write_contents
 228         routine, if writing, before calling target-dependent
 229         close_and_cleanup routine (which is now always generic, I think).
 230         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 231         close_and_cleanup and move code from it to
 232         srec_write_object_contents.  Add write_contents to tvec.
 233         * targets.c:  Remove a.out little vector, replace a.out big
 234         vector with SunOS vector.  FIXME:  Need Vax support again now.
 235
 236         * libbfd.h:  Add write_contents format-dependent-vector to the
 237         bfd_target vector.  Supply a generic close_and_cleanup routine.
 238         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 239         all routines defined in aout.c.  Rename "sunos" things to "aout"
 240         things.  Add a few fields where needed for various formats.
 241         * Makefile.in:  Add aout.c and newsos.c.
 242
 243         * archive.c, ieee.c, oasys.c:  Lint.
 244
 245 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 246
 247         * ../include/bfd.h
 248         changed forward declaration struct stat; to reduce warnings. Changed
 249         comment on bfd_h_<x>_x.
 250
 251         * ../include/m68kcoff.h, ../include/intel-coff.h,
 252         ../include/m88k-bcs.h
 253         Now there are two incarnations of relocs, linenos and syments. One for
 254         internal digestion, and one full of char arrays for I/O. The original
 255         names have gone to detect errors.
 256
 257         * Makefile.in, m68kcoff.c, targets.c
 258         Test new structure code with a 68k coff implementaion
 259
 260         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 261         Fixed all the places where there were problems with the size and
 262         alignments of structures on disk and structures in memory. #ifed out
 263         all the code in coffswap.c, since it should be done using the target
 264         swap routines now.
 265
 266 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 267
 268         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 269         multiple reloc command.
 270
 271         * sunos.c (sunos4_set_section_contents): Made it so that sections
 272         are always padded to their alignment size.
 273
 274 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 275
 276         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 277         Clean up types and such (saber C problems).
 278         * ecoff.c:  Clean up types and such.  Remove routines that are
 279         not used.  Fix up reading and swapping of shorts from files.
 280
 281    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 282
 283         * a.out.vax.c: Remove two bogus "static" from prototypes.
 284
 285         * ecoff.c: Got rid of lots of non-working junk (that had
 286         been copied directly from coff-code.h).
 287         Updated to be consistent with updates to icoff.c and coff-code.h.
 288
 289         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 290         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 291
 292         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 293         but until the target_vector is automatically generated,
 294         it's as good as any. Note that the text offset is the only
 295         difference between NewsOS and SunOs (including magic numbers).
 296         (Most of the sunos_* routines should to renamed bsd_*
 297         and move to a bsd.c file. Then (and when the target_vector
 298         is automatically generated) it might make sense to create
 299         a separate Sony target.)
 300
 301         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 302         on some systems, and doesn't help on others.
 303         Similarly, only define X_OK if not already defined.
 304
 305         * trad-core.c: Don't include sys/stat.h - at least
 306         on NewsOS 3, it has already been included.
 307
 308 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 309
 310         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 311         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 312         symbol tables if necessary when reading them in, so gdb can use
 313         them.  Add "bfd_coff_" to the names so they won't conflict with
 314         names in calling programs.  FIXME-soon:  if coff-code.h is
 315         included in two BFD modules, this will cause duplicate
 316         definitions; the routines should be exported to a separate,
 317         common, module (probably along with a mess of other ones).
 318
 319 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 320
 321         Improve modtime support.
 322
 323         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 324         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 325         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 326         BUG:  archive members still do not get correct mod times.
 327
 328         Improve floating point support for core files.
 329
 330         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 331         (sunos4_core_file_p):  Create a second registers section in the
 332         core file, called ".reg2", for the float registers.
 333
 334 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 335
 336         * many changes to improve archive handling; found a logic flaw in
 337           bfd_check_format which only just happened to work by cooncidence.
 338
 339 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 340
 341         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 342         correctly.
 343
 344         * bfd.h: changed type of udata in asymbol to void *, like it
 345         should be. Added bfd_reloc_dangerous enum member.
 346
 347         * coff-code.h: Fixed it so that internally generated symbols get
 348         their values relocated correctly in all cases. Removed calls to
 349         xmalloc.
 350
 351         * icoff.c: Not understanding the destination symbol of a reloc is
 352         not a failure any more, just 'dangerous'. This allows linking of
 353         b.out and coff images.
 354
 355         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 356         calculated.

 359 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 360
 361         * sunos.c (translate_to_native_sym_flags): fixed
 362         sym_pointer->n_value so that symbols on the way out get their
 363         section relative values calculated correctly.
 364
 365         * coff-code.h (mangle_symbols): fixed problem where tags were not
 366         being relocated for structs, enums, unions. Also various lints.
 367
 368 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 369
 370         * archive.c (get_elt_at_filepos): system_call_error returned
 371           incorrectly.
 372
 373 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 374
 375         * Resolve the use of no_error and system_call_error.
 376           The bfd library itself now will never set bfd_error to
 377           no_error.
 378
 379           The code still needs to be combed to make sure all the error
 380           codes are correct.  I suspect they are not always set correctly.
 381
 382         * The names of all the messages have _ prepended because the sun
 383           bundled compiler can't distinguish from a macro which takes an
 384           argument and the same identifier in a non-macro context.
 385
 386         * The reason for the above being that entry points which used to
 387           be trampoline functions are now just macros which expand to a
 388           direct call through the bfd's xfer vector.
 389
 390         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 391           must gas have its own version of everything (the gas version
 392           had the correct value)
 393
 394 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 395
 396         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 397         properly support i960 architecture and output correct reloc stuff.
 398
 399         * bfd.h: added prototype for bfd_printable_arch_mach, added
 400         BFD_FAIL
 401
 402         * coff-code.h: Applied patches from chrisb to support i960
 403         architecture, zero relocs and swap them correcly and conditionally
 404         compiled the timestamp.
 405
 406         * sunos.c: Made the default section alignment 2^3 so that doubles
 407         are done properly. Fixed the same reloc bug that was in b.out.c
 408
 409         * sysdep.h: Now compiles on a Posix box
 410
 411 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 412
 413         * icoff.c:  Fix comment on big-endian version.
 414         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 415         F_RELFLG).  Set F_AR32WR in output files if little endian
 416         architecture.
 417
 418 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 419
 420         * archures.c fixed =/== typo
 421
 422         * sunos.c added architecture stuff for output. Fixed
 423         bug where files where vma(data) != size(text)
 424         were processed wrong.
 425
 426         * coff-code.h added a lint cast
 427
 428         * (../include/a.out.sun4.h) fixed it so zmagic
 429         worked
 430
 431 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 432
 433         * archive.c removed loads of includes, and fixed bug where string
 434         table didn't have a null at the end.
 435
 436         * bfd.c fixed includes, added symbols argument to
 437         canonicalize_reloc entry point.
 438
 439         * libbfd.c fixed includes and added some lint patches.
 440
 441         * targets.c added both sorts of intel coff.
 442
 443         * b.out.c fixed included, changed was the canonical
 444         relocs were done.
 445
 446         * icoff.c added support for callj and big and little
 447         enidian tables.
 448
 449         * opncls.c added chmod+xing for files with EXEC_P set.
 450
 451         * sunos.c fixed includes. Changed default section
 452         alignement to words. Fixed relocation stuff to work with
 453         new scheme
 454
 455         * bfd.h various new types added, prototype for new
 456         reloc calls, changed bfd->iostream to a void *
 457         to including files don't need stdio.h.
 458
 459         * libcoff.h added conversion table to tie relocs to
 460         canonical symbols
 461
 462         * sysdep.h created
 463
 464         * coff-code.h fixed includes. Added code to support
 465         big and little endian formats. Various lints. Better
 466         processing of symbols. Changed reloc stuff to new
 467         order
 468
 469         * libbfd.h fixed includes
 470
 471
 472 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
 473
 474         * bfd.h changed name of alignment entry in sec_struct to
 475         alignment_power, because of conflicting uses within bfd.
 476         Now it should be obvious that it's a 2**n alignment
 477         specifier. Removed start_pad, end_alignment, block, minsize,
 478         output_file_alignment, subsection_alignment and original_vma fields.
 479         Added align_power() macro. Fixed bfd_section_alignment
 480         acessor macros. Added bfd_symbol_same_target macro.
 481
 482         * b.out.c (b_out_write_object_contents) fixed to use
 483         new alignment member. Fixed (callj_callback) to use section
 484         relative symbols properly.
 485
 486         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 487         Fixed (translate_from_native_sym_flags) to correctly make
 488         symbols section relative.
 489
 490         * bfd.c (bfd_errmsg) fixed various enum cast problems.
 491         (bfd_make_section) took out initialization of obsolete members.
 492         (bfd_print_symbol_vandf) added
 493
 494         * opncls.c (bfd_create) created.
 495
 496         * coff-code.h (coff_new_section_hook) took away refs
 497         to obsolete members. (make_a_section_from_file) added
 498         conversion between alignment types. (coff_symbol_from)
 499         added. (coff_count_linenumbers) only counts linenumbers
 500         if symbol is of coff-type. (coff_mangle_symbols) only
 501         heavily mangles symbols if symbol is coff-type.
 502         (coff_write_symbols) various lints. (coff_write_object_contents)
 503         various lints and modification for alignment conversion.
 504         (coff_slurp_relocs) fixed for use with new asection shape.
 505

 507
 508         * archive.c lots of lint
 509
 510         * b.out.c added callj relocation support, upgrated reloc howto.
 511         Fixed so that asymbol and reloc records are output
 512         correctly.
 513
 514         * bfd.c lots of lint, support for new bfd entry point
 515         bfd_print_symbol.
 516
 517         * bfd.h changed definition of asymbol to contain pointer to
 518         owning bfd, removed target dependencies.
 519
 520         * cache.c took out print statements, put in BFD_ASSERT calls.
 521
 522         * coff-code.h various lints, corrected linenumber output
 523         functionality. Added support for new style asymbols and
 524         bfd_print_symbol. Fixed so that asymbol and
 525         reloc records are handled correctly. Added timestamp.
 526
 527         * icoff.c Added support for new howto shape.
 528

 539
 540 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 541
 542         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 543         pointer lint. Added support for callj relocation. Fixed bug where
 544         the last 32 bytes of the text section were overwritten by data. Fixed bug
 545         where archives of b.out didn't work due bfd_slurp_extended_name_table
 546         returning false.
 547
 548         * sunos.c added support for n_other field. Braced the howto table so
 549         that it won't be affected by any lengthing of the howto struct typedef.
 550         Various lints
 551
 552         * bfd.h added support for n_other field, added special_function

 557
 558 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 559
 560         * ChangeLog:  Started ChangeLog for BFD.
 561         * ToDo:  Create file for suggestions.
 562
 563         * Makefile:  Support easy loading into Saber C.
 564         Add dependencies for icoff.o and bcs88kcoff.o.
 565         Rename coff.c to coff-code.h.  Change callers.
 566
 567         * bfd.c (bfd_check_format):  Allow the check_format routines
 568         to return the desired target vector, rather than just a Boolean.
 569         bfd.h (bfd_check_format):  Change function pointer return type.
 570         archive.c (bfd_generic_archive_p):  change callee.
 571         b.out.c (b_out_little_object_p, b_out_big_object_p,
 572         b_out_real_object_p):  change callee.
 573         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 574         in check_format transfer vectors that need a filler.
 575         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 576         bcs88kcoff.c:  change callee.
 577         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 578         icoff.c:  change callee.
 579         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 580
 581         * libbfd.c (zalloc):  It should actually zero the storage!
 582         This was commented out for some reason.
 583
 584         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 585         This is so callers can avoid <stdlib.h> which doesn't exist
 586         on older systems.
 587
 588         * bfd.c (map_over_sections):  Add debugging code, since I
 589         noticed the section count for sunos core files was bad, but only
 590         GDB had detected the problem.
 591         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 592         bfd_get_section_linenos):  Remove obsolete functions.
 593         (bfd_apply_relocations):  Use longs, not ints, for the math.
 594
 595         * bfd.h:  Declare enum boolean and struct bfd_target as well
 596         as typedefs for them.  Remove obsolete
 597         bfd_get_section_lineno_size.
 598
 599         * cache.c:  Make the "fdopen" support work.  Keep better track
 600         of how many files are open.  Centralize the opening of files
 601         and be sure bfd_open[rw] actually try to open the file.  Evade
 602         linked list initialization problems.
 603
 604         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 605
 606         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 607
 608         * cplus-dem.c:  Delete file, since it is not part of BFD.
 609
 610         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 611         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 612
 613         * sunos.c (sunos4_core_file_p):  Set section count.
 614         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 615         obsolete definitions.
 616         (_write_symbol_table):  Initialize <idx> counter.
 617         (foop):  Eliminate debugging code.
 618
 619
 620
 621
