bfd/ChangeLog

   1 Tue Oct  1 12:29:44 1991  John Gilmore  (gnu at cygnus.com)
   2
   3         * Makefile.in, configure.in, targets.c, elf.c:  Add preliminary
   4         ELF support good enough for GDB.
   5         * configure.in, config/h-amix, config/t-m68k-elf:  Handle
   6         m68k-cbm-svr4 host and target.
   7         * config/t-m68k-coff, t-m88k-coff, t-m88k-aout:  Make files nonempty
   8         so `diff' and `patch' can cope.
   9
  10 Tue Oct  1 11:24:31 1991  Steve Chamberlain  (steve at cygnus.com)
  11
  12         * archures.c: removed texinfo error
  13
  14         * init.c: added texinfo hooks, and removed initialization error
  15         message.
  16
  17         * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
  18         without complaints.
  19
  20 Tue Oct  1 05:02:53 1991  John Gilmore  (gnu at cygnus.com)
  21
  22         * cpu-i960.c:  Avoid numerical count of initializers.
  23
  24         Vax Ultrix changes from David Taylor <taylor@think.com>:
  25         * host-aout.c:  Make little-endian vector really little-endian.
  26         * configure.in:  Separate vax and tahoe cases, handle ultrix.
  27         * config/t-vax:  Add trad-core.o.
  28         * config/h-vaxult:  New host system.
  29
  30 Mon Sep 30 15:13:46 1991  Steve Chamberlain  (steve at cygnus.com)
  31
  32         * bfd-in.h VERSION, change version number to 0.18, this makes a
  33         gap, but now is the same as the linker version number.
  34
  35         * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
  36         cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
  37         files will eventually contain processor specific bits for bfd,
  38         like strange relocation information and dis/assembly.  So far only
  39         the H8 has been even partially done.  This work also ties in with
  40         the change in handling architectures.
  41
  42         * amdcoff.c: (a29k_reloc) fix error message.
  43
  44         * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
  45         discover the architecture of the bfd. (sunos4_callback) calls the
  46         function bfd_set_arch_mach rather than stuffing stuff directly
  47         into the bfd. (sunos4_write_object_contents), changed names of
  48         accessor functions.
  49
  50         * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
  51         setup the environment.
  52
  53         * archive.c: (bfd_slurp_coff_armap) coff archives always have the
  54         headers in big endian format, regardless of the endianess of the
  55         host or target.
  56
  57         * archures.c: totally changed. Now an architecture is represented
  58         with a pointer to an info structure rather than an enumerated type
  59         and a long. The old info is available as two elements in the
  60         structure.  Future enhancements to architecure support will
  61         involve pointers to methods being placed into the info structure.
  62
  63         * bfd.c: changed the definition of the bfd structure for the new
  64         architecture stuff.
  65
  66         * bout.c: (b_out_set_arch_mach) changed to use the new
  67         architecture mechanism.
  68
  69         * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
  70         the new architecture mechanism.
  71
  72         * configure.in: added h8 stuff.
  73
  74         * ieee.c: too many changes to note.  Now ieee files written with
  75         bfd gas and ld can be read by gld and ieee only linkers and
  76         simulators.
  77
  78         * libbfd.c, libbfd.h: changed prototype of bfd_write.
  79
  80         * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
  81         than fixing the structure directly.
  82
  83         * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
  84         than fixing the structure directly.
  85
  86         * opncls.c: (new_bfd) makes sure that bfd_init has been called
  87         before opening a bfd.
  88
  89         * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
  90         rather than fixing the structure directly.
  91
  92         * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
  93         in the t/hmake file) a user can select which backends they want
  94         linked with bfd without changing the source.
  95
  96         * init.c: new, looks after initializing modules.
  97
  98         * howto.c: for future use, will allow an application to work out
  99         what cookie to use as a handle on a relcoatio howto.
 100
 101 Mon Sep 30 13:31:15 1991  John Gilmore  (gnu at cygnus.com)
 102
 103         * srec.c:  Better error checking, partly from Peter Schauer.
 104         (srec_object_p):  Avoid assuming any file that starts with 'S' is
 105         an S-record file!  (Check for 3 uppercase-hex digits after it.)
 106         (ISHEX):  Define new macro for checking supposedly hex characters.
 107         (pass_over):  Treat as EOF any S-record line that:
 108             *  doesn't have hex in either size character
 109             *  produces a size larger than 0x7F
 110             *  has an unrecognized type number
 111
 112 Thu Sep 26 15:27:29 1991  John Gilmore  (gnu at cygnus.com)
 113
 114         * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
 115         opncls.c:  Lint (saber actually).
 116
 117 Thu Sep 26 11:24:24 1991  Per Bothner  (bothner at cygnus.com)
 118
 119         * libaout.h (WRITE_HEADERS): Set header's a_text field always.
 120         * newsos3.c: Fixed two types: newos3 -> newsos3.
 121         * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
 122         to use correct segment.
 123
 124 Mon Sep 23 18:24:34 1991  Per Bothner  (bothner at cygnus.com)
 125
 126         * aoutx.h (print_symbol):  Handle missing symbol->name.
 127
 128 Fri Sep 20 12:26:01 1991  Stu Grossman  (grossman at cygnus.com)
 129

 146         crude dependencies.
 147
 148         * coffcode.h (coff_real_object_p):  Pass information about the
 149         current file's coff symbol format to BFD via the coff_data struct.
 150         (coff_find_nearest_line):  obj_icof => coff_data.
 151         (coff_swap_sym_{in,out}):  Check that SYMNMLEN == E_SYMNMLEN.

 153         and DIMNUM == E_DIMNUM.
 154         * configure.in:  Handle a29k-*-* hosts, and targets
 155         a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
 156         * libcoff-in.h:  Add local_n_btmask, local_n_btshft,

 189         to h/t-xxxx files so that everything will work on System V.
 190
 191 Fri Aug 23 13:51:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
 192
 193         * aoutx.h:  Add information on host-aout.c and how to configure
 194         to use it, to the manual.
 195         * configure.in:  Tix typo.
 196         * ecoff.c:  If compiling for DEC3100, use trad_unix core files,

 198         * trad-core.c (trad_unix_core_file_p):  If HOST_DATA_START_ADDR is
 199         specified, use it to locate the data section.
 200         * coffcode.h (coff_write_symbols):  Declare buffer as bfd_bytes
 201         rather than as chars (lint).
 202

 204
 205         * aoutx.h, coffcode.h:  saberized.

 212
 213
 214 Wed Aug 21 19:13:22 1991  John Gilmore  (gnu at cygint.cygnus.com)
 215
 216         * trad-core.c (trad_unix_core_file_p):  Use HOST_TEXT_START_ADDR,
 217         etc, rather than TEXT_START_ADDR.
 218         * host-aout.c:  Remove #if 0 around whole thing.
 219         Update to modern (32/64-bit) a.out naming conventions.
 220         Include a large chunk of ../include/a.out.gnu.h to get macros that
 221         are not defined by the system include files.
 222         (host_aout_{32,64}_write_object_contents):  Use the WRITE_HEADERS

 225
 226 Wed Aug 21 14:33:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 227
 228         * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
 229         texdoc and psdoc; make these depend on generated .texi's

 238         libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
 239         libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
 240         libbfd.h, and libcoff.h; (b) in generated parts of same, use less
 241         obtrusive marks indicating .c origins.
 242
 243         * bfd.texinfo: generalize most references to linker
 244
 245 Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 246
 247         * Makefile.in: include core.p in PROTOS (building better bfd.h)

 249
 250 Mon Aug 19 13:48:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 251
 252         * bfd.texinfo: use @setchapternewpage on instead of lots of
 253         @page's; minor rephrasing in Introduction.

 260
 261
 262 Thu Aug  8 16:47:43 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 263
 264         * coffcode.h: fixed bug where string table size wasn't being swapped.
 265
 266 Thu Aug  1 16:35:28 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 267
 268         * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags
 269
 270         * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT
 271         flags. (bfd_print_symbol_vandf) now knows what to do with the
 272         above flags.
 273
 274         * aoutx.h: made translate_from_native_sym_flags and
 275         translate_to_native_sym_flags produce the above flags.
 276
 277
 278 Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
 279
 280         * all files:  update copyright notices for GPL version 2.
 281         Install header comments and attribute most modules to their
 282         authors.  BFD's name is now officially "Binary File Descriptor",
 283         so remove any conflicting pejoratives.
 284         archures.h:  Consists solely of comments; remove it.
 285
 286 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 287
 288         * Makefile.in, bfd.c: Made it compile again.
 289
 290 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 291
 292         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
 293
 294
 295 Mon Jul 15 16:27:42 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 296
 297         * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c
 298         bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on
 299         lint fixes.
 300
 301         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
 302         29k coff by David Wood (wood@lab.ultra.nyu.edu).
 303
 304 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 305
 306         * Everything: created some new files, core.c format.c, reloc.c,
 307         section.c and syms.c to split the functionality a bit better.
 308         Cleaned up the rest of the files a bit, and added some
 309         documentation.
 310
 311
 312 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 313
 314         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
 315         really takes 3 arguments, patched code and ammended prototypes.
 316
 317 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 318
 319         * ../include/bfd.h (struct bfd_target): Added new field
 320         "align_power_min" which contains the minimum alignment for a
 321         section. This is used in coff_new_section_hook. The field
 322         insertion necessitates an update of all backends..
 323
 324         * aoutf1.h jump table field inserted
 325
 326         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 327         filenames too.
 328
 329         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 330         table field inserted.
 331
 332         * coffcode.h(just about everything) Now patches up symbol tables
 333         using a different mechanism. The Intel major bug has been fixed,
 334         and the linker can self host on the Aviion and be debugged with
 335         gdb.
 336
 337         * ecoff.c: new include and jump table patch, i386coff.c: new
 338         include and jump table patch,  icoff.c: new include and jump table
 339         patch, ieee.c: can now read archives containing ieee modules.,
 340         libcoff.h: added (combined_entry_type), libieee.h: uped max
 341         sections to 20, m68kcoff.c: new include and jump table patch,
 342         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 343         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.

 345
 346 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 347
 348         * coffcode.h (coff_swap_aux_in): added else case to deal with
 349         filenames less than 9 characters.
 350
 351
 352 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 353
 354         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 355
 356         * srec.c: now allows any number of sections to be created in a
 357         file. Outputs addresses of the right length.
 358
 359 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 360
 361         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 362         target didn't match, the format got set to the attempted match,
 363         breaking a future test.
 364
 365         *../include/i386coff.h : fixed typo in type field with size
 366
 367         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 368         support in the jump table for the swapping routines exported to
 369         gdb. Now gdb works with the 386.
 370
 371 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 372
 373         * Merge in changes from gdb-3.95 release.
 374         Makefile.in:  Allow hmake and tmake files to add OFILES.
 375         aoutf1.h:
 376         bfd.c:  support specific targets as well as searching.  When
 377         searching, take default target in preference to others.
 378         bfd.doc:  typos
 379         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 380         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 381         libbfd.h:  Support specific targets as well as searching.
 382         opncls.c:  Support specific targets as well as searching.
 383         targets.c:  Search is short-circuited if default target matches.
 384         liboasys.c, libieee.c:  Undo bothner changes that make macros
 385         work to the left of assignment, but which depend on the
 386         representations of different pointer types being the same.
 387
 388 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 389
 390         * i386coff.c: created.
 391         * coffcode.h: added support for 386.
 392         * Makefile.in: added support for 386.
 393         * ../include/i386coff.h: created
 394
 395 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 396
 397         * coffcode.h: removed all put_x_<sizes>
 398         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 399         DEFUNS
 400
 401
 402 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 403         (bothner)
 404         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 405
 406 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 407
 408         * everything: Removed sysdep.h from bfd.h and put back into files
 409         from which it was split out. Now 64 bit version is built with a
 410         -DHOST_64_BIT="long long" on the compile line.
 411
 412
 413 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 414
 415         Changed all the [get|put][name] routines to use  [get|put]_[size
 416         in bytes].
 417
 418         Put in support for 64 bit work. Now two versions of bfd may be
 419         generated, according to the state of TARGET_64_BIT, one which is
 420         32 bit only, and one which is 64/32 bits.
 421         Created new back end 'demo64' to test 64 bit functionality.
 422
 423         Renamed some files to work on DOS.
 424
 425         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 426         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 427         chage, 64 bit transfer. * liba.out.h: Split out common code from
 428         sunos and newsos into liba.out. Name changes and prototype mods. *
 429         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 430         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 431         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 432         change and 64bit stuff.* newsos3.c: common code removed, new jump
 433         table. * oasys.c: Name change * opncls.c: Portability fixes *
 434         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 435         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 436         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 437         64bit ized. * demo64.c: 64 bit a.out back end
 438
 439

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

 697
 698         * icoff.c:  Fix comment on big-endian version.
 699         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 700         F_RELFLG).  Set F_AR32WR in output files if little endian
 701         architecture.

 758
 759         * bfd.h changed name of alignment entry in sec_struct to
 760         alignment_power, because of conflicting uses within bfd.
 761         Now it should be obvious that it's a 2**n alignment
 762         specifier. Removed start_pad, end_alignment, block, minsize,

 771         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 772         Fixed (translate_from_native_sym_flags) to correctly make
 773         symbols section relative.

 783         conversion between alignment types. (coff_symbol_from)
 784         added. (coff_count_linenumbers) only counts linenumbers
 785         if symbol is of coff-type. (coff_mangle_symbols) only
 786         heavily mangles symbols if symbol is coff-type.

 800         bfd_print_symbol.
 801
 802         * bfd.h changed definition of asymbol to contain pointer to
 803         owning bfd, removed target dependencies.
 804
 805         * cache.c took out print statements, put in BFD_ASSERT calls.
 806
 807         * coff-code.h various lints, corrected linenumber output
 808         functionality. Added support for new style asymbols and

 826
 827         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 828         pointer lint. Added support for callj relocation. Fixed bug where
 829         the last 32 bytes of the text section were overwritten by data. Fixed bug
 830         where archives of b.out didn't work due bfd_slurp_extended_name_table
 831         returning false.
 832
 833         * sunos.c added support for n_other field. Braced the howto table so
 834         that it won't be affected by any lengthing of the howto struct typedef.

 843 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 844
 845         * ChangeLog:  Started ChangeLog for BFD.
 846         * ToDo:  Create file for suggestions.
 847
 848         * Makefile:  Support easy loading into Saber C.
 849         Add dependencies for icoff.o and bcs88kcoff.o.
 850         Rename coff.c to coff-code.h.  Change callers.
 851
 852         * bfd.c (bfd_check_format):  Allow the check_format routines
 853         to return the desired target vector, rather than just a Boolean.
 854         bfd.h (bfd_check_format):  Change function pointer return type.
 855         archive.c (bfd_generic_archive_p):  change callee.
 856         b.out.c (b_out_little_object_p, b_out_big_object_p,
 857         b_out_real_object_p):  change callee.
 858         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 859         in check_format transfer vectors that need a filler.
 860         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 861         bcs88kcoff.c:  change callee.
 862         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 863         icoff.c:  change callee.
 864         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 865
 866         * libbfd.c (zalloc):  It should actually zero the storage!
 867         This was commented out for some reason.
 868
 869         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 870         This is so callers can avoid <stdlib.h> which doesn't exist
 871         on older systems.
 872
 873         * bfd.c (map_over_sections):  Add debugging code, since I
 874         noticed the section count for sunos core files was bad, but only
 875         GDB had detected the problem.
 876         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 877         bfd_get_section_linenos):  Remove obsolete functions.
 878         (bfd_apply_relocations):  Use longs, not ints, for the math.
 879
 880         * bfd.h:  Declare enum boolean and struct bfd_target as well
 881         as typedefs for them.  Remove obsolete
 882         bfd_get_section_lineno_size.
 883
 884         * cache.c:  Make the "fdopen" support work.  Keep better track
 885         of how many files are open.  Centralize the opening of files
 886         and be sure bfd_open[rw] actually try to open the file.  Evade
 887         linked list initialization problems.
 888
 889         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 890
 891         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 892
 893         * cplus-dem.c:  Delete file, since it is not part of BFD.
 894
 895         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 896         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 897
 898         * sunos.c (sunos4_core_file_p):  Set section count.
 899         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 900         obsolete definitions.
 901         (_write_symbol_table):  Initialize <idx> counter.
 902         (foop):  Eliminate debugging code.
