   2
   3         RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
   4         John Gilmore.
   5
   6         * Makefile.in:  Add cpu-rs6000.c and rs6000coff.c.
   7         * configure.in:  Add rs6000 case.
   8         * targets.c:  Add rs6000 vector.
   9         * archures.c:  Add rs6000, fix comment on romp.
  10         * bfd-in.h (enum bfd_error):  Add no_debug_section error.
  11         * libcoff-in.h (struct coff_tdata):  Remove unused string_table.
  12         * bfd.c (bfd_errmsgs):  Add no_debug_section error message.
  13         * section.c (bfd_make_section):  Return NULL on attempt to create
  14         a section twice.
  15         * coffcode.h (bfd_swap_reloc_in):  Handle r_type and r_size.
  16         (bfd_swap_aouthdr_in):  Handle lots more members.
  17         (make_a_section_from_file):  If section has already been seen,
  18         just return false rather than overwriting it.
  19         (coff_real_object_p):  Understand incoming magic numbers.
  20         (coff_set_flags):  Understand outgoing magic numbers.
  21         (coff_compute_section_file_positions):  outgoing aouthdr magic #.
  22         (build_debug_section):  Add fn for reading debug string section.
  23         (get_normalized_symtab):  Handle symbol names in debug string section.

  28
  29 Thu Oct 24 02:03:24 1991  Fred Fish  (fnf at cygnus.com)
  30
  31         * elf.c: Add partial support for ELF format corefiles. Still needs
  32         support for extracting registers from corefiles.
  33
  34         * config/t-m68k-elf:  Set DEFAULT_VECTOR to elf_big_vec.
  35
  36         * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
  37         RANLIB is defined as echo, send the output to /dev/null to help
  38         reduce clutter in the output from doing a make.
  39
  40 Mon Oct 21 17:48:48 1991  John Gilmore  (gnu at cygnus.com)
  41
  42         * hosts/h-vaxult.h:  Remove malloc/free decls covered in stdlib.h.
  43         Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE.  From David Taylor.
  44
  45 Mon Oct 21 09:34:11 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
  46
  47         * coffcode.h (coff_compute_section_file_positions): make it pad
  48         section size out if there are alignment restrictions so that the
  49         image will be ok on a system where section positions are worked
  50         out by accumulating sizes rather than from the section headers.
  51         * targets.c (proto write_armap). Changed orl_count to unsigned.
  52         * opncls.c (bfd_close_all_done). Added so that generative
  53         programs like gas can close a bfd without causing bfd confusion.
  54         * libbfd.h (changed becuase of protos)
  55         * amdcoff.c: messed with the way that jmp displacements are
  56         calcualated. This may not yet be totally correct.
  57         * archive.c (coff_write_armap): rewrote the way that ranlibs are
  58         written out.
  59         * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
  60         abs symbol has no section (like a register symbol).
  61         (coff_write_symbol) now zeros auxent before filling it up to help
  62         with sensitive applications.
  63         * libbfd.c (bfd_write_bigendian_4byte_int): added.
  64
  65 Wed Oct 16 22:58:45 1991  John Gilmore  (gnu at cygnus.com)
  66
  67         * bfd.c:  Make sure we don't get a macro strerror().
  68         * opncls.c (bfd_fdopenr):  If FASCIST_FDOPEN, use "r", not "r+".
  69         * trad-core.c (trad_unix_core_file_failing_command):  Suppress
  70         attempt to recover command, ifdef NO_CORE_COMMAND.
  71         * hosts/h-tahoe.h:  Add FASCIST_FDOPEN and NO_CORE_COMMAND;
  72         revamp HOST_*, etc.
  73         * hosts/h-i386v.h:  Use <utime.h>, not <sys/utime.h>, unlike POSIX.
  74
  75 Wed Oct 16 12:43:49 1991  Per Bothner  (bothner at cygnus.com)
  76
  77         * archive.c (bsd_write_argmap): The size of the ranlib structures
  78         should not include the size field itself.
  79         * aoutx.h, libaout.h (NAME(aout, sizeof_headers)):  Use
  80         adata(abfd)->exec_bytes_size field instead of constant macro,
  81         because aoutx.h compiles to a simple .o file shared by
  82         all 32-bits a.out targets.
  83
  84 Wed Oct 16 11:11:05 1991  John Gilmore  (gnu at cygnus.com)
  85
  86         * configure.in:  Allow i386-sco-sysv.
  87         * bout.c:  Remove unused i960_align; lint dummy core file handlers.
  88         * cpu-h8300.c:  lint.
  89
  90         * host-aout.c:  New strategy.  We use common code, include files,
  91         and data structures to handle the file, but set a few parameters
  92         from the host's config file (page size, text start addr, etc).
  93         * libaout.h:  Define HP BSD machine types.
  94         * aoutf1.h:  Handle reading a.outs with these types.
  95
  96         * trad-core.c:  Pass the u.u_ar0 value as the negative of the
  97         virtual-memory-address of the .reg section.  We can't just make a
  98         section for "all the regs and nothing else" because only GDB knows
  99         exactly where the regs are (scattered around the upage and stack).
 100         Clean up memory allocation.  Remove big- and little-endian
 101         vectors, replace with single vector; this only runs on the host,
 102         in host byte order.  Replace byteswap routines with aborts in case
 103         anyone calls them.
 104         * targets.c:  There's only one trad_core_vec now.
 105         * aoutf1.h (sunos_core_file_p):  VMA of .reg* now needs to be 0.
 106
 107 Tue Oct 15 08:29:03 1991  John Gilmore  (gnu at cygnus.com)
 108
 109         * hosts/h-amix.h (free):  Fix prototype.
 110
 111         * aoutx.h:  Don't use NULL as an integer, for braindead systems
 112         that declare it as (void *)0.  (From Peter Schauer.)
 113
 114 Mon Oct 14 17:20:47 1991  Per Bothner  (bothner at cygnus.com)
 115
 116         * opncls.c (bfd_fdopenr):  Add parentheses to avoid reported
 117         problem with bad Ultrix system headers.
 118         * aoutx.h (NAME(aout,set_section_contents)):  Try to handle the
 119         various kinds of alignments for the various kinds of
 120         magic numbers.
 121
 122 Mon Oct 14 14:23:10 1991  John Gilmore  (gnu at cygnus.com)
 123
 124         * doc/Makefile:  Don't assume . is on the path (from James Clark).
 125
 126 Fri Oct 11 22:45:14 1991  John Gilmore  (gnu at cygnus.com)
 127
 128         * Makefile.in:  Avoid Sun Make VPATH bugs.
 129         * targets.c:  Declare trad_core vectors extern.
 130
 131 Fri Oct 11 13:03:02 1991  Per Bothner  (bothner at cygnus.com)
 132
 133         * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
 134         * libbfd.h: Moved ALIGN macro here.
 135         * bout.c (b_out_callback): Replace i960_align by align_power.
 136
 137         * libaout.h (struct aoutdata):  Added fields page_size,
 138         segment_size and exec_bytes_size.  These help generic code
 139         (in aoutx.h and libaout.h) to figure out where to align
 140         the various segments in a demand paged file.
 141         * libaout.h (WRITE_HEADER):  Use new (struct aoutdata) fields
 142         to decide if the exec header counts in a_text (text segment size).
 143         Also, assume D_PAGED flag is set; don't set it here.
 144         * bout.c (b_out_callback): Add initialization of
 145         adata fields page_size, segment_size, and exec_bytes_size.
 146         * host-aout.c (NAME(host_aout, callback) and
 147         NAME(host_aout,mkobject): Ditto.
 148         * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
 149         * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
 150         * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
 151         * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
 152         EXEC_BYTES_SIZE from the a_test size; this is only appropriate
 153         for some systems (mainly sunos), so do it in the callback instead.
 154         Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
 155         * aoutx.h (NAME(aout,set_section_contents): Change the way
 156         filepos and size of sections are carried out to support
 157         older styles of demand paged executables.
 158
 159
 160 Fri Oct 11 12:33:36 1991  Steve Chamberlain  (steve at cygnus.com)
 161
 162         * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
 163         * bfd.c: Added macros to enable gas to swap coff records.
 164         * coffcode.h: Make the coff_swap_*_out routines return the number
 165         of bytes swapped, and cleaned up their prototypes.
 166         * configure.in: Added ebmon/coff support
 167         * ecoff.c: Changed null definitions of coff_swap_*_out to conform
 168         to new prototypes
 169         * targets.c: Added new entry points for coff swapping
 170
 171 Fri Oct 11 03:01:52 1991  John Gilmore  (gnu at cygnus.com)
 172
 173         Restructure configuration scheme for bfd, binutils, ld.
 174
 175         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 176         * configure.in:  Revise to symlink sysdep.h to hosts/h-xxx.h.
 177         Change some config names to match other dirs.
 178         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 179         get defined first.
 180         * Makefile.in:  Use -I. to get sysdep.h.  Remove refs to
 181         ../include/sysdep.h.
 182         * cpu-i960.c:  Strncmp needed a length arg.
 183         * ecoff.c:  Don't ever call trad_unix_core_file_p from here.
 184         * i386aout.c:  Remove dead N_TXTOFF override.
 185         * trad-core.c:  Don't disable the whole file if SUN4_SYS.
 186         * config/:  Rename some config files to match up h-*.h names.
 187         Remove all the HOST_SYS definitions from the config files.
 188         * hosts/h-amix.h, h-i386v.h:  Define POSIX_UTIME, not USG.
 189         * hosts/h-hp9000.h:  Remove USG comment.
 190         * hosts/h-rs6000.h:  Include <stdlib.h> for malloc.
 191         * hosts/h-news.h, h-sparc-64.h:  New config files that had
 192         previously been kludged in the <sysdep.h> file.
 193
 194 Thu Oct 10 17:54:08 1991  John Gilmore  (gnu at cygnus.com)
 195
 196         * config/*:  trad-core support is HOST dependent, not target
 197         dependent.  Target config files only set DEFAULT_VECTOR and/or
 198         other vector elements.  Exception:  when host-aout.c is in use,
 199         in which case we're forced to assume we're native (hp, vax,
 200         tahoe).  Rename XDEPFILES to HDEPFILES.
 201         * Makefile.in:  Rename XDEPFILES.
 202         * config/h-sun*:  Don't force static linking.
 203         * trad-core.c:  Document how to use it nowadays.
 204         * i386aout.c, newsos3.c:  Clean up.
 205         * i386coff.c:  Allow 386 coff files to be used as core files too
 206         (for reading core files from embedded systems).
 207
 208 Tue Oct  8 15:30:39 1991  John Gilmore  (gnu at cygnus.com)
 209
 210         * Add i386aout.c for a.out support on the i386.
 211
 212 Tue Oct  8 12:18:54 1991  Roland H. Pesch  (pesch at cygnus.com)
 213
 214         * reloc.c, section.c, syms.c, targets.c: correct info-node
 215         structure in *doc* comments.
 216         doc/Makefile: stop hiding complaints from makeinfo.
 217
 218 Sun Oct  6 19:10:06 1991  John Gilmore  (gnu at cygnus.com)
 219
 220         * aoutx.h (...some_aout_object_p):  Take a third parameter,
 221         the internal_exec struct, and avoid ever looking at an
 222         external_exec.  All callers changed to read the entire
 223         external_exec struct, swap and check its magic number,
 224         swap in the whole structure, and pass the swapped-in version to
 225         some_aout_object_p.
 226         * bout.c:  Bring into modern era.  Use single _object_p routine
 227         for big- aand little-endian.  Provide internal and external
 228         exec header structs.  Use separate swap-in and swap-out routines.
 229
 230         * libaout.h:  Move struct internal_exec from ../include/aout64.h
 231         to here.  Add obj_symbol_entry_size to struct aoutdata.
 232         * aoutx.h (...some_aout_object_p):  Set obj_symbol_entry_size.
 233
 234         * ../include/aout64.h:  Change EXTERNAL_LIST_SIZE to
 235         EXTERNAL_NLIST_SIZE.  Callers changed.
 236
 237 Fri Oct  4 18:18:46 1991  John Gilmore  (gnu at cygnus.com)
 238
 239         * bfd.c:  Remove strerror() to libiberty.
 240
 241         * elf.c:  Remove elf_set_section_contents, use generic one.  Lint.
 242         * libbfd-in.h, libbfd.c:  Add bfd_generic_set_section_contents.
 243         * libbfd.c (bfd_generic_{get,set}_section_contents):  Check that
 244         last byte of transfer, not first byte, is within the section.
 245
 246         * host-aout.c:  Remove `BSD' archive support.  Lint.
 247
 248         * archures.c: Rename `struct bfd_arch_info_struct' to `struct
 249         bfd_arch_info'.  Rename `typedef bfd_arch_info_struct_type' to
 250         `bfd_arch_info_type'.  All uses changed.
 251         * reloc.c:  Rename `bfd_reloc_status_enum_type' to
 252         `bfd_reloc_status_type'.  Rename `bfd_reloc_code_enum_real_type'
 253         to `bfd_reloc_code_real_type'.  (This seems to be a misnomer,
 254         it needs a better name.)  All uses changed.
 255         * targets.c:  Rename `enum target_flavour_enum' to `enum
 256         target_flavour', and remove the `_enum' from all of the enum
 257         values themselves.  All uses changed.
 258
 259         * configure.in, config/h-i386mach:  i386 mach host.
 260         * config/t-i386-aout:  Use host-aout.c.
 261
 262         * trad-core.c:  Give it its own xvec's to make it independent
 263         of other file formats.
 264         * ecoff.c, host-aout.c:  Remove refs to trad-core.
 265         * config/t-dec3100, t-hp300bsd, t-tahoe, t-vax:  Define TRAD_CORE.
 266         * targets.c:  #ifdef TRAD_CORE, include it in the vector.
 267
 268 Fri Oct  4 17:38:03 1991  Steve Chamberlain  (steve at cygnus.com)
 269
 270         * reloc.c: Extended NEWHOWTO macro
 271         * ieee.c: Changed the way 8bit pcrel is done
 272         * cpu-h8300.c: got the registers in the right order
 273
 274 Thu Oct  3 19:39:55 1991  John Gilmore  (gnu at cygnus.com)
 275
 276         * bfd-in.h:  enum boolean => enum bfd_boolean for SVR4.  Gumby's
 277         prediction is vindicated!
 278
 279         * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
 280         Remove refs to howto.c, since Steve forgot.
 281
 282 Thu Oct  3 07:49:21 1991  Steve Chamberlain  (steve at cygnus.com)
 283
 284         * elf.c: took the abort out of set_arch_mach so that objdump -i will
 285         still work. Now allows any architecture/machine to be set.
 286
 287 Wed Oct  2 13:50:35 1991  Steve Chamberlain  (steve at cygnus.com)
 288
 289         * howto.c deleted and moved code to reloc.c
 290
 291         * libbfd.h, libbfd-in.h removed $id stuff for real
 292
 293         * cpu-h8300.c Made it match various different spellings of h8300.
 294
 295         * archures.c: Took out the first char filter which made it only
 296         look for a cpu/arch match when the first chars of supplied and
 297         tested names were the same.
 298
 299         * targets.c removed oasys stuff, pending someone to fix the bugs
 300         in it.
 301
 302
 303 Tue Oct  1 12:29:44 1991  John Gilmore  (gnu at cygnus.com)
 304
 305         * Makefile.in, configure.in, targets.c, elf.c:  Add preliminary
 306         ELF support good enough for GDB.
 307         * configure.in, config/h-amix, config/t-m68k-elf:  Handle
 308         m68k-cbm-svr4 host and target.
 309         * config/t-m68k-coff, t-m88k-coff, t-m88k-aout:  Make files nonempty
 310         so `diff' and `patch' can cope.
 311
 312 Tue Oct  1 11:24:31 1991  Steve Chamberlain  (steve at cygnus.com)
 313
 314         * archures.c: removed texinfo error
 315
 316         * init.c: added texinfo hooks, and removed initialization error
 317         message.
 318
 319         * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
 320         without complaints.
 321
 322 Tue Oct  1 05:02:53 1991  John Gilmore  (gnu at cygnus.com)
 323
 324         * cpu-i960.c:  Avoid numerical count of initializers.
 325
 326         Vax Ultrix changes from David Taylor <taylor@think.com>:
 327         * host-aout.c:  Make little-endian vector really little-endian.
 328         * configure.in:  Separate vax and tahoe cases, handle ultrix.
 329         * config/t-vax:  Add trad-core.o.
 330         * config/h-vaxult:  New host system.
 331
 332 Mon Sep 30 15:13:46 1991  Steve Chamberlain  (steve at cygnus.com)
 333
 334         * bfd-in.h VERSION, change version number to 0.18, this makes a
 335         gap, but now is the same as the linker version number.
 336
 337         * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
 338         cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
 339         files will eventually contain processor specific bits for bfd,
 340         like strange relocation information and dis/assembly.  So far only
 341         the H8 has been even partially done.  This work also ties in with
 342         the change in handling architectures.
 343
 344         * amdcoff.c: (a29k_reloc) fix error message.
 345
 346         * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
 347         discover the architecture of the bfd. (sunos4_callback) calls the
 348         function bfd_set_arch_mach rather than stuffing stuff directly
 349         into the bfd. (sunos4_write_object_contents), changed names of
 350         accessor functions.
 351
 352         * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
 353         setup the environment.
 354
 355         * archive.c: (bfd_slurp_coff_armap) coff archives always have the
 356         headers in big endian format, regardless of the endianess of the
 357         host or target.
 358
 359         * archures.c: totally changed. Now an architecture is represented
 360         with a pointer to an info structure rather than an enumerated type
 361         and a long. The old info is available as two elements in the
 362         structure.  Future enhancements to architecure support will
 363         involve pointers to methods being placed into the info structure.
 364
 365         * bfd.c: changed the definition of the bfd structure for the new
 366         architecture stuff.
 367
 368         * bout.c: (b_out_set_arch_mach) changed to use the new
 369         architecture mechanism.
 370
 371         * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
 372         the new architecture mechanism.
 373
 374         * configure.in: added h8 stuff.
 375
 376         * ieee.c: too many changes to note.  Now ieee files written with
 377         bfd gas and ld can be read by gld and ieee only linkers and
 378         simulators.
 379
 380         * libbfd.c, libbfd.h: changed prototype of bfd_write.
 381
 382         * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
 383         than fixing the structure directly.
 384
 385         * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
 386         than fixing the structure directly.
 387
 388         * opncls.c: (new_bfd) makes sure that bfd_init has been called
 389         before opening a bfd.
 390
 391         * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
 392         rather than fixing the structure directly.
 393
 394         * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
 395         in the t/hmake file) a user can select which backends they want
 396         linked with bfd without changing the source.
 397
 398         * init.c: new, looks after initializing modules.
 399
 400         * howto.c: for future use, will allow an application to work out
 401         what cookie to use as a handle on a relcoatio howto.
 402
 403 Mon Sep 30 13:31:15 1991  John Gilmore  (gnu at cygnus.com)
 404
 405         * srec.c:  Better error checking, partly from Peter Schauer.
 406         (srec_object_p):  Avoid assuming any file that starts with 'S' is
 407         an S-record file!  (Check for 3 uppercase-hex digits after it.)
 408         (ISHEX):  Define new macro for checking supposedly hex characters.
 409         (pass_over):  Treat as EOF any S-record line that:
 410             *  doesn't have hex in either size character
 411             *  produces a size larger than 0x7F
 412             *  has an unrecognized type number
 413
 414 Thu Sep 26 15:27:29 1991  John Gilmore  (gnu at cygnus.com)
 415
 416         * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
 417         opncls.c:  Lint (saber actually).
 418
 419 Thu Sep 26 11:24:24 1991  Per Bothner  (bothner at cygnus.com)
 420
 421         * libaout.h (WRITE_HEADERS): Set header's a_text field always.
 422         * newsos3.c: Fixed two types: newos3 -> newsos3.
 423         * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
 424         to use correct segment.
 425
 426 Mon Sep 23 18:24:34 1991  Per Bothner  (bothner at cygnus.com)
 427
 428         * aoutx.h (print_symbol):  Handle missing symbol->name.
 429
 430 Fri Sep 20 12:26:01 1991  Stu Grossman  (grossman at cygnus.com)
 431
 432         * aoutf1.h (swapcore_sparc):  Change name of USRSTACK, fix comment
 433         at top of routine.
 434
 435 Tue Sep 17 17:23:49 1991  Stu Grossman  (grossman at cygnus.com)
 436
 437         * oasys.c, configure.in, config/h-irix3, config/t-irix3:

 448         crude dependencies.
 449
 450         * coffcode.h (coff_real_object_p):  Pass information about the
 451         current file's coff symbol format to BFD via the coff_data struct.
 452         (coff_find_nearest_line):  obj_icof => coff_data.
 453         (coff_swap_sym_{in,out}):  Check that SYMNMLEN == E_SYMNMLEN.
 454         (coff_swap_aux_{in,out}):  Check that FILNMLEN == E_FILNMLEN
 455         and DIMNUM == E_DIMNUM.
 456         * configure.in:  Handle a29k-*-* hosts, and targets
 457         a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
 458         * libcoff-in.h:  Add local_n_btmask, local_n_btshft,
 459         local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
 460         local_linesz to `coff_data' (tdata) struct.
 461         (coff_data, coff_data_type, coff_tdata):  Rename struct icofdata.
 462         * config/h-ultra3:  Handle a29k-*-* hosts as Ultracomputers.

 464 Thu Sep 12 14:07:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 465

 468
 469 Tue Sep 10 20:34:12 1991  John Gilmore  (gnu at cygint.cygnus.com)
 470
 471         * aoutf1.h (sunos4_core_file_p):  Release the right storage in
 472         error case.

 491         to h/t-xxxx files so that everything will work on System V.
 492
 493 Fri Aug 23 13:51:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
 494
 495         * aoutx.h:  Add information on host-aout.c and how to configure
 496         to use it, to the manual.
 497         * configure.in:  Tix typo.
 498         * ecoff.c:  If compiling for DEC3100, use trad_unix core files,
 499         else dummy out the core file support.
 500         * trad-core.c (trad_unix_core_file_p):  If HOST_DATA_START_ADDR is
 501         specified, use it to locate the data section.
 502         * coffcode.h (coff_write_symbols):  Declare buffer as bfd_bytes
 503         rather than as chars (lint).
 504

 506
 507         * aoutx.h, coffcode.h:  saberized.

 509 Thu Aug 22 11:27:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 510
 511         * bfd.texinfo: some cleanup, reincorporated more intro matter from
 512         bfd.doc
 513         bfd.c, targets.c: minor rewording of doc segments
 514
 515
 516 Wed Aug 21 19:13:22 1991  John Gilmore  (gnu at cygint.cygnus.com)
 517
 518         * trad-core.c (trad_unix_core_file_p):  Use HOST_TEXT_START_ADDR,

 523         are not defined by the system include files.
 524         (host_aout_{32,64}_write_object_contents):  Use the WRITE_HEADERS
 525         macro used by the other a.out implementations.

 527
 528 Wed Aug 21 14:33:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 529
 530         * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
 531         texdoc and psdoc; make these depend on generated .texi's

 534         doc
 535

 539         * Makefile.in, awkscan-ip, awkscan-p, intobfd,
 540         libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
 541         libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
 542         libbfd.h, and libcoff.h; (b) in generated parts of same, use less
 543         obtrusive marks indicating .c origins.
 544
 545         * bfd.texinfo: generalize most references to linker
 546
 547 Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 548
 549         * Makefile.in: include core.p in PROTOS (building better bfd.h)

 551
 552 Mon Aug 19 13:48:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 553
 554         * bfd.texinfo: use @setchapternewpage on instead of lots of
 555         @page's; minor rephrasing in Introduction.
 556
 557         * aoutx.h, archive.c, archures.c, bfd.c, bfd.texinfo, cache.c,
 558         coffcode.h, core.c, format.c, ieee.c, libbfd.c, libbfd.h, libcoff.h,

 565
 566         * coffcode.h: fixed bug where string table size wasn't being swapped.
 567
 568 Thu Aug  1 16:35:28 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 569
 570         * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags
 571
 572         * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT
 573         flags. (bfd_print_symbol_vandf) now knows what to do with the
 574         above flags.
 575
 576         * aoutx.h: made translate_from_native_sym_flags and
 577         translate_to_native_sym_flags produce the above flags.
 578

 580 Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
 581
 582         * all files:  update copyright notices for GPL version 2.
 583         Install header comments and attribute most modules to their
 584         authors.  BFD's name is now officially "Binary File Descriptor",
 585         so remove any conflicting pejoratives.
 586         archures.h:  Consists solely of comments; remove it.
 587
 588 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 589
 590         * Makefile.in, bfd.c: Made it compile again.
 591
 592 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 593
 594         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
 595
 596

 601         lint fixes.
 602
 603         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
 604         29k coff by David Wood (wood@lab.ultra.nyu.edu).
 605
 606 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 607
 608         * Everything: created some new files, core.c format.c, reloc.c,
 609         section.c and syms.c to split the functionality a bit better.
 610         Cleaned up the rest of the files a bit, and added some
 611         documentation.
 612
 613
 614 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 615
 616         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
 617         really takes 3 arguments, patched code and ammended prototypes.
 618
 619 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 620
 621         * ../include/bfd.h (struct bfd_target): Added new field
 622         "align_power_min" which contains the minimum alignment for a
 623         section. This is used in coff_new_section_hook. The field
 624         insertion necessitates an update of all backends..
 625
 626         * aoutf1.h jump table field inserted
 627
 628         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 629         filenames too.
 630
 631         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 632         table field inserted.
 633
 634         * coffcode.h(just about everything) Now patches up symbol tables
 635         using a different mechanism. The Intel major bug has been fixed,
 636         and the linker can self host on the Aviion and be debugged with
 637         gdb.
 638
 639         * ecoff.c: new include and jump table patch, i386coff.c: new
 640         include and jump table patch,  icoff.c: new include and jump table
 641         patch, ieee.c: can now read archives containing ieee modules.,
 642         libcoff.h: added (combined_entry_type), libieee.h: uped max
 643         sections to 20, m68kcoff.c: new include and jump table patch,
 644         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 645         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
 646         srec.c: jump table patch. trad-code.c fixed #IF typeo
 647
 648 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 649
 650         * coffcode.h (coff_swap_aux_in): added else case to deal with
 651         filenames less than 9 characters.
 652
 653
 654 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 655
 656         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 657
 658         * srec.c: now allows any number of sections to be created in a
 659         file. Outputs addresses of the right length.
 660
 661 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 662
 663         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 664         target didn't match, the format got set to the attempted match,
 665         breaking a future test.
 666
 667         *../include/i386coff.h : fixed typo in type field with size
 668
 669         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 670         support in the jump table for the swapping routines exported to
 671         gdb. Now gdb works with the 386.
 672
 673 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 674
 675         * Merge in changes from gdb-3.95 release.
 676         Makefile.in:  Allow hmake and tmake files to add OFILES.
 677         aoutf1.h:
 678         bfd.c:  support specific targets as well as searching.  When
 679         searching, take default target in preference to others.
 680         bfd.doc:  typos
 681         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 682         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 683         libbfd.h:  Support specific targets as well as searching.
 684         opncls.c:  Support specific targets as well as searching.
 685         targets.c:  Search is short-circuited if default target matches.
 686         liboasys.c, libieee.c:  Undo bothner changes that make macros
 687         work to the left of assignment, but which depend on the
 688         representations of different pointer types being the same.
 689
 690 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 691
 692         * i386coff.c: created.
 693         * coffcode.h: added support for 386.
 694         * Makefile.in: added support for 386.
 695         * ../include/i386coff.h: created
 696
 697 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 698
 699         * coffcode.h: removed all put_x_<sizes>
 700         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 701         DEFUNS
 702
 703
 704 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 705         (bothner)
 706         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 707
 708 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 709
 710         * everything: Removed sysdep.h from bfd.h and put back into files
 711         from which it was split out. Now 64 bit version is built with a
 712         -DHOST_64_BIT="long long" on the compile line.
 713
 714
 715 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 716
 717         Changed all the [get|put][name] routines to use  [get|put]_[size
 718         in bytes].
 719
 720         Put in support for 64 bit work. Now two versions of bfd may be
 721         generated, according to the state of TARGET_64_BIT, one which is
 722         32 bit only, and one which is 64/32 bits.
 723         Created new back end 'demo64' to test 64 bit functionality.
 724
 725         Renamed some files to work on DOS.
 726
 727         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 728         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 729         chage, 64 bit transfer. * liba.out.h: Split out common code from
 730         sunos and newsos into liba.out. Name changes and prototype mods. *
 731         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 732         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 733         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 734         change and 64bit stuff.* newsos3.c: common code removed, new jump
 735         table. * oasys.c: Name change * opncls.c: Portability fixes *
 736         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 737         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 738         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 739         64bit ized. * demo64.c: 64 bit a.out back end

 745 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 746         from bothner
 747         * libieee.h: Make ieee_data and ieee_ar_data macros usable
 748         on LHS of assignment, even when using old compilers.
 749         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 750         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 751         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 752         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 753         * targets.c: Add declaration of newsos3_vec.
 754
 755
 756 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 757
 758         * aout.c: fixxed some of the problems with filepos calculation.
 759         (swap_ext_reloc): fixed problem with creation of relocs.
 760         (aout_set_section_contents): fixed filepos problem
 761
 762         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 763         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 764         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 765         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 766         cleaned up. (coff_write_object_contents) cleaned up.
 767
 768         * ecoff.c: Totally different. Now supports ecoff fully.
 769
 770         * icoff.c: fixed problems in relocation callout.
 771
 772         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 773
 774         * m68kcoff.c: updated target vector.
 775
 776         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 777         choose_reloc_size. (sunos4_write_object_contents) now calls
 778         choose_reloc_size so outputs relocs correctly, also calculates the
 779         size of the sections correctly.
 780
 781
 782
 783 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 784
 785         Merge Per Bothner's changes to modularize BFD a.out a bit.
 786
 787         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 788         * ieee.c:  Cast enums to int before comparing them, for brain-
 789         dead compilers.
 790         * coff-code.h:  Remove coff_get_section_contents, and use the
 791         generic one instead.
 792
 793         * aout.c:  Derive new module from sunos.c, containing generic
 794         support code for all kinds of a.out files.
 795
 796         * sunos.c: Remove all code that goes in aout.c.  Split out
 797         machine dependent followup in sunos4_object_p into
 798         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 799         and redefine only the names we CHANGE, not all the names.  Drop
 800         the little-endian vector, and rename the vector as sunos4 rather
 801         than generic.
 802
 803         * b.out.c:  Use aout.c routines for most of the work.  Slight
 804         changes for the new regime.  Remove close_and_cleanup and
 805         get_section_contents in favor of generics.  New transfer vector
 806         regime.
 807
 808         * newsos.c:  New support for Sony NEWS, another a.out format.
 809
 810         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 811         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 812         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 813         to tvec.
 814         * opncls.c (bfd_close):  Call format-dependent write_contents
 815         routine, if writing, before calling target-dependent
 816         close_and_cleanup routine (which is now always generic, I think).
 817         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 818         close_and_cleanup and move code from it to
 819         srec_write_object_contents.  Add write_contents to tvec.
 820         * targets.c:  Remove a.out little vector, replace a.out big
 821         vector with SunOS vector.  FIXME:  Need Vax support again now.
 822
 823         * libbfd.h:  Add write_contents format-dependent-vector to the
 824         bfd_target vector.  Supply a generic close_and_cleanup routine.
 825         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 826         all routines defined in aout.c.  Rename "sunos" things to "aout"
 827         things.  Add a few fields where needed for various formats.
 828         * Makefile.in:  Add aout.c and newsos.c.
 829
 830         * archive.c, ieee.c, oasys.c:  Lint.
 831
 832 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 833
 834         * ../include/bfd.h
 835         changed forward declaration struct stat; to reduce warnings. Changed
 836         comment on bfd_h_<x>_x.
 837
 838         * ../include/m68kcoff.h, ../include/intel-coff.h,
 839         ../include/m88k-bcs.h
 840         Now there are two incarnations of relocs, linenos and syments. One for
 841         internal digestion, and one full of char arrays for I/O. The original
 842         names have gone to detect errors.
 843
 844         * Makefile.in, m68kcoff.c, targets.c
 845         Test new structure code with a 68k coff implementaion
 846
 847         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 848         Fixed all the places where there were problems with the size and
 849         alignments of structures on disk and structures in memory. #ifed out
 850         all the code in coffswap.c, since it should be done using the target
 851         swap routines now.
 852
 853 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 854
 855         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 856         multiple reloc command.
 857
 858         * sunos.c (sunos4_set_section_contents): Made it so that sections
 859         are always padded to their alignment size.
 860
 861 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 862
 863         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 864         Clean up types and such (saber C problems).
 865         * ecoff.c:  Clean up types and such.  Remove routines that are
 866         not used.  Fix up reading and swapping of shorts from files.
 867
 868    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 869
 870         * a.out.vax.c: Remove two bogus "static" from prototypes.
 871
 872         * ecoff.c: Got rid of lots of non-working junk (that had
 873         been copied directly from coff-code.h).
 874         Updated to be consistent with updates to icoff.c and coff-code.h.
 875
 876         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 877         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 878
 879         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 880         but until the target_vector is automatically generated,
 881         it's as good as any. Note that the text offset is the only
 882         difference between NewsOS and SunOs (including magic numbers).
 883         (Most of the sunos_* routines should to renamed bsd_*
 884         and move to a bsd.c file. Then (and when the target_vector
 885         is automatically generated) it might make sense to create
 886         a separate Sony target.)
 887
 888         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 889         on some systems, and doesn't help on others.
 890         Similarly, only define X_OK if not already defined.
 891
 892         * trad-core.c: Don't include sys/stat.h - at least
 893         on NewsOS 3, it has already been included.
 894
 895 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 896
 897         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 898         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 899         symbol tables if necessary when reading them in, so gdb can use
 900         them.  Add "bfd_coff_" to the names so they won't conflict with
 901         names in calling programs.  FIXME-soon:  if coff-code.h is
 902         included in two BFD modules, this will cause duplicate
 903         definitions; the routines should be exported to a separate,
 904         common, module (probably along with a mess of other ones).
 905
 906 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 907
 908         Improve modtime support.
 909
 910         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 911         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 912         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 913         BUG:  archive members still do not get correct mod times.
 914
 915         Improve floating point support for core files.
 916
 917         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 918         (sunos4_core_file_p):  Create a second registers section in the
 919         core file, called ".reg2", for the float registers.
 920
 921 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 922
 923         * many changes to improve archive handling; found a logic flaw in
 924           bfd_check_format which only just happened to work by cooncidence.
 925
 926 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 927
 928         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 929         correctly.
 930
 931         * bfd.h: changed type of udata in asymbol to void *, like it
 932         should be. Added bfd_reloc_dangerous enum member.
 933
 934         * coff-code.h: Fixed it so that internally generated symbols get
 935         their values relocated correctly in all cases. Removed calls to
 936         xmalloc.
 937
 938         * icoff.c: Not understanding the destination symbol of a reloc is
 939         not a failure any more, just 'dangerous'. This allows linking of
 940         b.out and coff images.
 941
 942         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 943         calculated.
 944
 945
 946 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 947
 948         * sunos.c (translate_to_native_sym_flags): fixed
 949         sym_pointer->n_value so that symbols on the way out get their
 950         section relative values calculated correctly.
 951
 952         * coff-code.h (mangle_symbols): fixed problem where tags were not
 953         being relocated for structs, enums, unions. Also various lints.
 954
 955 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 956
 957         * archive.c (get_elt_at_filepos): system_call_error returned
 958           incorrectly.
 959
 960 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 961
 962         * Resolve the use of no_error and system_call_error.
 963           The bfd library itself now will never set bfd_error to
 964           no_error.
 965
 966           The code still needs to be combed to make sure all the error
 967           codes are correct.  I suspect they are not always set correctly.
 968
 969         * The names of all the messages have _ prepended because the sun
 970           bundled compiler can't distinguish from a macro which takes an
 971           argument and the same identifier in a non-macro context.
 972
 973         * The reason for the above being that entry points which used to
 974           be trampoline functions are now just macros which expand to a
 975           direct call through the bfd's xfer vector.
 976
 977         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 978           must gas have its own version of everything (the gas version
 979           had the correct value)
 980
 981 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 982
 983         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 984         properly support i960 architecture and output correct reloc stuff.
 985
 986         * bfd.h: added prototype for bfd_printable_arch_mach, added
 987         BFD_FAIL
 988
 989         * coff-code.h: Applied patches from chrisb to support i960
 990         architecture, zero relocs and swap them correcly and conditionally
 991         compiled the timestamp.
 992
 993         * sunos.c: Made the default section alignment 2^3 so that doubles
 994         are done properly. Fixed the same reloc bug that was in b.out.c
 995
 996         * sysdep.h: Now compiles on a Posix box
 997
 998 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 999
1000         * icoff.c:  Fix comment on big-endian version.
1001         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
1002         F_RELFLG).  Set F_AR32WR in output files if little endian
1003         architecture.
1004
1005 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1006
1007         * archures.c fixed =/== typo
1008
1009         * sunos.c added architecture stuff for output. Fixed
1010         bug where files where vma(data) != size(text)

1059 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1060
1061         * bfd.h changed name of alignment entry in sec_struct to
1062         alignment_power, because of conflicting uses within bfd.
1063         Now it should be obvious that it's a 2**n alignment
1064         specifier. Removed start_pad, end_alignment, block, minsize,

1085         conversion between alignment types. (coff_symbol_from)
1086         added. (coff_count_linenumbers) only counts linenumbers
1087         if symbol is of coff-type. (coff_mangle_symbols) only

1102         bfd_print_symbol.
1103
1104         * bfd.h changed definition of asymbol to contain pointer to
1105         owning bfd, removed target dependencies.
1106
1107         * cache.c took out print statements, put in BFD_ASSERT calls.

1129         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1130         pointer lint. Added support for callj relocation. Fixed bug where
1131         the last 32 bytes of the text section were overwritten by data. Fixed bug
1132         where archives of b.out didn't work due bfd_slurp_extended_name_table
1133         returning false.
1134
1135         * sunos.c added support for n_other field. Braced the howto table so
1136         that it won't be affected by any lengthing of the howto struct typedef.

1145 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
1146
1147         * ChangeLog:  Started ChangeLog for BFD.
1148         * ToDo:  Create file for suggestions.
1149
1150         * Makefile:  Support easy loading into Saber C.
1151         Add dependencies for icoff.o and bcs88kcoff.o.
1152         Rename coff.c to coff-code.h.  Change callers.
1153
1154         * bfd.c (bfd_check_format):  Allow the check_format routines
1155         to return the desired target vector, rather than just a Boolean.
1156         bfd.h (bfd_check_format):  Change function pointer return type.
1157         archive.c (bfd_generic_archive_p):  change callee.
1158         b.out.c (b_out_little_object_p, b_out_big_object_p,
1159         b_out_real_object_p):  change callee.
1160         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
1161         in check_format transfer vectors that need a filler.
1162         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
1163         bcs88kcoff.c:  change callee.
1164         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
1165         icoff.c:  change callee.
1166         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
1167
1168         * libbfd.c (zalloc):  It should actually zero the storage!
1169         This was commented out for some reason.
1170
1171         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
1172         This is so callers can avoid <stdlib.h> which doesn't exist
1173         on older systems.
1174
1175         * bfd.c (map_over_sections):  Add debugging code, since I
1176         noticed the section count for sunos core files was bad, but only
1177         GDB had detected the problem.
1178         (bfd_set_section_lineno_size, bfd_set_section_linenos,
1179         bfd_get_section_linenos):  Remove obsolete functions.
1180         (bfd_apply_relocations):  Use longs, not ints, for the math.
1181
1182         * bfd.h:  Declare enum boolean and struct bfd_target as well
1183         as typedefs for them.  Remove obsolete
1184         bfd_get_section_lineno_size.
1185
1186         * cache.c:  Make the "fdopen" support work.  Keep better track
1187         of how many files are open.  Centralize the opening of files
1188         and be sure bfd_open[rw] actually try to open the file.  Evade
1189         linked list initialization problems.
1190
1191         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
1192
1193         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
1194
1195         * cplus-dem.c:  Delete file, since it is not part of BFD.
1196
1197         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
1198         (bfd_openr, bfd_openw):  Actually open the file, give error now.
1199
1200         * sunos.c (sunos4_core_file_p):  Set section count.
1201         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
1202         obsolete definitions.
1203         (_write_symbol_table):  Initialize <idx> counter.
1204         (foop):  Eliminate debugging code.
