bfd/ChangeLog

   1 Mon Nov 11 18:36:47 1991  Per Bothner  (bothner at cygnus.com)
   2
   3         * aoutx.h (NAME(aout,find_nearest_line)):  Handle the case
   4         of two N_SO stabs, one for directory, and one for filename.
   5
   6         * bfd-in.h (print_vma):  Factor out duplicate definition.
   7
   8         Exit a little more gracefully when malloc returns NULL.
   9         * libbfd.c: New function bfd_xmalloc (malloc wrapper).
  10         * opncls.c, syms.c, bout.c, aoutx.h:  Replace malloc by bfd_xmalloc.
  11         * libbfd.h: Rre-generated due to libbfd.c update.
  12
  13 Sat Nov  9 13:45:01 1991  Fred Fish  (fnf at cygnus.com)
  14
  15         * config/mt-m68k-elf:  Define DEFAULT_VECTOR as elf_big_vec.
  16
  17         * elf.c (elf_object_p):  Don't try to create a bfd section for
  18         the first ELF section header.  It is just a placeholder.
  19
  20 Sat Nov  9 03:04:26 1991  John Gilmore  (gnu at cygnus.com)
  21
  22         * coff-rs6000.c, config/mh-rs6000:  Make it work on archive and
  23         core files, when compiling native.
  24         * hosts/h-rs6000.h:  Define FASCIST_FDOPEN for bfd_fdopenr.
  25
  26         FIXME:  The aoutf1.h change below needs to be reversed back
  27         to the way it was.
  28
  29 Thu Nov  7 11:03:55 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
  30
  31         * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
  32         manipulation of lnno fields in lineno structs in a coff-<f>.h
  33         independent way. Override it in coff-<f>.h to your favourite
  34         number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
  35         (coff_swap_lineno_out): modified to use the new macros.
  36
  37 Mon Nov  4 11:38:33 1991  Steve Chamberlain  (sac at cygnus.com)
  38
  39         * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
  40         unknown arch when the magic number doesn't specify the
  41         architecture, since some OSs (eg old sun3s) don't set the number, and
  42         020 is probably the right answer anyway.
  43
  44 Sun Nov  3 12:07:08 1991  Per Bothner  (bothner at cygnus.com)
  45
  46         * hosts/h-news.h, hosts/h-rtbsd.h:
  47         Get rid of MISSING_VFPRINTF, since libiberty provides one.
  48         * bfd-in.h (bfd_print_symbol_type_hopw enum):   Add new option
  49         bfd_print_symbol_nm, for use by nm.
  50         * aoutx.h (NAME(aout,print_symbol)):  Add code for new
  51         bfd_print_symbol_nm option, to print in nm format.
  52         * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
  53         oasys.c (oasys_print_symbol):  Provide stub implementations
  54         for bfd_print_symbol_nm.
  55         * syms.c:  New function bfd_decode_symclass, used by nm printer.
  56         New function bfd_stab_name to look up string name of stab code.
  57
  58 Sat Nov  2 14:26:03 1991  Steve Chamberlain  (steve at cygnus.com)
  59
  60         * Makefile.in: Added ctor.c
  61         * archures.c (bfd_default_arch_struct) added
  62         bfd_default_reloc_type_lookup.
  63         * coffcode.h: removed a load of #if 0ed code.
  64         (coff_compute_file_section_positions): now works out the section
  65         alignment and size correctly in all cases.
  66         (coff_get_symtab): looks for constructor symbols and calls the
  67         right function when they're found. (coff_canonicalize_reloc):
  68         knows when a section is full of constructors and does the right
  69         thing.
  70         * cpu-m88k.c: Added default_reloc_type lookup to the architecture
  71         description.
  72         * libbfd-in.h: (bfd_default_reloc_type_lookup) defun  added.
  73         * libcoff.h: removed #if 0ed code
  74         * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
  75         arch independent constructor relocation type.
  76         (bfd_reloc_type_lookup): removed the comment "this will go away"
  77         since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
  78         reloc which is used when BFD_RELOC_CTOR falls through to give a
  79         default 32bit reloc for constructors.
  80         (bfd_default_reloc_type_lookup): added.
  81         * aoutf1.h: fixed SEGMENT_SIZE typo.
  82
  83 Thu Oct 31 18:23:06 1991  John Gilmore  (gnu at cygnus.com)
  84
  85         * coff-rs6000.c:  Change name to "aixcoff-rs6000", to avoid
  86         matching prefix "coff".
  87         * coffcode.h (coff_swap_aux_in, coff_swap_aux_out):  Handle
  88         rs/6000 csect records.
  89
  90 Sun Oct 27 16:56:58 1991  Steve Chamberlain  (steve at cygnus.com)
  91
  92         * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
  93         * configure.in: add motorola delta88 cases
  94         * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
  95         write_armap prototype
  96         * libbfd.c: add doc on bfd_write_bigendian_4byte_int
  97
  98 Fri Oct 25 02:48:19 1991  John Gilmore  (gnu at cygnus.com)
  99
 100         * Rename COFF-related files in `coff-ARCH.c' form.
 101         coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
 102         coff-mips.c, coff-rs6000.c to be exact.
 103
 104         * Makefile.in:  Only supply TARGET_DEFAULTS to targets.c, reducing
 105         make output clutter.
 106         * config/mt-*:  Ditto.
 107
 108 Thu Oct 24 22:40:07 1991  John Gilmore  (gnu at cygnus.com)
 109
 110         RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
 111         John Gilmore.  Archive support from Damon A. Permezel.
 112
 113         * Makefile.in:  Add cpu-rs6000.c and rs6000coff.c.
 114         * configure.in:  Add rs6000 case.
 115         * targets.c:  Add rs6000 vector.
 116         * archures.c:  Add rs6000, fix comment on romp.
 117         * bfd-in.h (enum bfd_error):  Add no_debug_section error.
 118         * libcoff-in.h (struct coff_tdata):  Remove unused string_table.
 119         * bfd.c (bfd_errmsgs):  Add no_debug_section error message.

 122         * coffcode.h (bfd_swap_reloc_in):  Handle r_type and r_size.
 123         (bfd_swap_aouthdr_in):  Handle lots more members.
 124         (make_a_section_from_file):  If section has already been seen,
 125         just return false rather than overwriting it.
 126         (coff_real_object_p):  Understand incoming magic numbers.
 127         (coff_set_flags):  Understand outgoing magic numbers.
 128         (coff_compute_section_file_positions):  outgoing aouthdr magic #.
 129         (build_debug_section):  Add fn for reading debug string section.
 130         (get_normalized_symtab):  Handle symbol names in debug string section.
 131         Remove unused obj_string_table.
 132         (coff_slurp_symbol_table):  Handle rs6000-specific storage classes.
 133         * aoutx.h (translate_from_native_sym_flags, N_SET*):  Check for
 134         existing section before making one.
 135         * cpu-rs6000.c:  New file.
 136         * rs6000coff.c:  New file.
 137
 138 Thu Oct 24 02:03:24 1991  Fred Fish  (fnf at cygnus.com)
 139
 140         * elf.c: Add partial support for ELF format corefiles. Still needs
 141         support for extracting registers from corefiles.
 142
 143         * config/t-m68k-elf:  Set DEFAULT_VECTOR to elf_big_vec.
 144
 145         * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
 146         RANLIB is defined as echo, send the output to /dev/null to help
 147         reduce clutter in the output from doing a make.
 148
 149 Mon Oct 21 17:48:48 1991  John Gilmore  (gnu at cygnus.com)
 150
 151         * hosts/h-vaxult.h:  Remove malloc/free decls covered in stdlib.h.
 152         Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE.  From David Taylor.
 153
 154 Mon Oct 21 09:34:11 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
 155
 156         * coffcode.h (coff_compute_section_file_positions): make it pad
 157         section size out if there are alignment restrictions so that the
 158         image will be ok on a system where section positions are worked
 159         out by accumulating sizes rather than from the section headers.
 160         * targets.c (proto write_armap). Changed orl_count to unsigned.
 161         * opncls.c (bfd_close_all_done). Added so that generative
 162         programs like gas can close a bfd without causing bfd confusion.
 163         * libbfd.h (changed becuase of protos)
 164         * amdcoff.c: messed with the way that jmp displacements are
 165         calcualated. This may not yet be totally correct.
 166         * archive.c (coff_write_armap): rewrote the way that ranlibs are
 167         written out.
 168         * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
 169         abs symbol has no section (like a register symbol).
 170         (coff_write_symbol) now zeros auxent before filling it up to help
 171         with sensitive applications.
 172         * libbfd.c (bfd_write_bigendian_4byte_int): added.
 173
 174 Wed Oct 16 22:58:45 1991  John Gilmore  (gnu at cygnus.com)
 175
 176         * bfd.c:  Make sure we don't get a macro strerror().
 177         * opncls.c (bfd_fdopenr):  If FASCIST_FDOPEN, use "r", not "r+".
 178         * trad-core.c (trad_unix_core_file_failing_command):  Suppress
 179         attempt to recover command, ifdef NO_CORE_COMMAND.
 180         * hosts/h-tahoe.h:  Add FASCIST_FDOPEN and NO_CORE_COMMAND;
 181         revamp HOST_*, etc.
 182         * hosts/h-i386v.h:  Use <utime.h>, not <sys/utime.h>, unlike POSIX.
 183
 184 Wed Oct 16 12:43:49 1991  Per Bothner  (bothner at cygnus.com)
 185
 186         * archive.c (bsd_write_argmap): The size of the ranlib structures
 187         should not include the size field itself.
 188         * aoutx.h, libaout.h (NAME(aout, sizeof_headers)):  Use
 189         adata(abfd)->exec_bytes_size field instead of constant macro,
 190         because aoutx.h compiles to a simple .o file shared by
 191         all 32-bits a.out targets.
 192
 193 Wed Oct 16 11:11:05 1991  John Gilmore  (gnu at cygnus.com)
 194
 195         * configure.in:  Allow i386-sco-sysv.
 196         * bout.c:  Remove unused i960_align; lint dummy core file handlers.
 197         * cpu-h8300.c:  lint.
 198
 199         * host-aout.c:  New strategy.  We use common code, include files,
 200         and data structures to handle the file, but set a few parameters
 201         from the host's config file (page size, text start addr, etc).
 202         * libaout.h:  Define HP BSD machine types.
 203         * aoutf1.h:  Handle reading a.outs with these types.
 204
 205         * trad-core.c:  Pass the u.u_ar0 value as the negative of the
 206         virtual-memory-address of the .reg section.  We can't just make a
 207         section for "all the regs and nothing else" because only GDB knows
 208         exactly where the regs are (scattered around the upage and stack).
 209         Clean up memory allocation.  Remove big- and little-endian
 210         vectors, replace with single vector; this only runs on the host,
 211         in host byte order.  Replace byteswap routines with aborts in case
 212         anyone calls them.
 213         * targets.c:  There's only one trad_core_vec now.
 214         * aoutf1.h (sunos_core_file_p):  VMA of .reg* now needs to be 0.
 215
 216 Tue Oct 15 08:29:03 1991  John Gilmore  (gnu at cygnus.com)
 217
 218         * hosts/h-amix.h (free):  Fix prototype.
 219
 220         * aoutx.h:  Don't use NULL as an integer, for braindead systems
 221         that declare it as (void *)0.  (From Peter Schauer.)
 222
 223 Mon Oct 14 17:20:47 1991  Per Bothner  (bothner at cygnus.com)
 224
 225         * opncls.c (bfd_fdopenr):  Add parentheses to avoid reported
 226         problem with bad Ultrix system headers.
 227         * aoutx.h (NAME(aout,set_section_contents)):  Try to handle the
 228         various kinds of alignments for the various kinds of
 229         magic numbers.
 230
 231 Mon Oct 14 14:23:10 1991  John Gilmore  (gnu at cygnus.com)
 232
 233         * doc/Makefile:  Don't assume . is on the path (from James Clark).
 234
 235 Fri Oct 11 22:45:14 1991  John Gilmore  (gnu at cygnus.com)
 236
 237         * Makefile.in:  Avoid Sun Make VPATH bugs.
 238         * targets.c:  Declare trad_core vectors extern.
 239
 240 Fri Oct 11 13:03:02 1991  Per Bothner  (bothner at cygnus.com)
 241
 242         * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
 243         * libbfd.h: Moved ALIGN macro here.
 244         * bout.c (b_out_callback): Replace i960_align by align_power.
 245
 246         * libaout.h (struct aoutdata):  Added fields page_size,
 247         segment_size and exec_bytes_size.  These help generic code
 248         (in aoutx.h and libaout.h) to figure out where to align
 249         the various segments in a demand paged file.
 250         * libaout.h (WRITE_HEADER):  Use new (struct aoutdata) fields
 251         to decide if the exec header counts in a_text (text segment size).
 252         Also, assume D_PAGED flag is set; don't set it here.
 253         * bout.c (b_out_callback): Add initialization of
 254         adata fields page_size, segment_size, and exec_bytes_size.
 255         * host-aout.c (NAME(host_aout, callback) and
 256         NAME(host_aout,mkobject): Ditto.
 257         * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
 258         * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
 259         * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
 260         * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
 261         EXEC_BYTES_SIZE from the a_test size; this is only appropriate
 262         for some systems (mainly sunos), so do it in the callback instead.
 263         Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
 264         * aoutx.h (NAME(aout,set_section_contents): Change the way
 265         filepos and size of sections are carried out to support
 266         older styles of demand paged executables.
 267
 268
 269 Fri Oct 11 12:33:36 1991  Steve Chamberlain  (steve at cygnus.com)
 270
 271         * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
 272         * bfd.c: Added macros to enable gas to swap coff records.
 273         * coffcode.h: Make the coff_swap_*_out routines return the number
 274         of bytes swapped, and cleaned up their prototypes.
 275         * configure.in: Added ebmon/coff support
 276         * ecoff.c: Changed null definitions of coff_swap_*_out to conform
 277         to new prototypes
 278         * targets.c: Added new entry points for coff swapping
 279
 280 Fri Oct 11 03:01:52 1991  John Gilmore  (gnu at cygnus.com)
 281
 282         Restructure configuration scheme for bfd, binutils, ld.
 283
 284         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 285         * configure.in:  Revise to symlink sysdep.h to hosts/h-xxx.h.
 286         Change some config names to match other dirs.
 287         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 288         get defined first.
 289         * Makefile.in:  Use -I. to get sysdep.h.  Remove refs to
 290         ../include/sysdep.h.
 291         * cpu-i960.c:  Strncmp needed a length arg.
 292         * ecoff.c:  Don't ever call trad_unix_core_file_p from here.
 293         * i386aout.c:  Remove dead N_TXTOFF override.
 294         * trad-core.c:  Don't disable the whole file if SUN4_SYS.
 295         * config/:  Rename some config files to match up h-*.h names.
 296         Remove all the HOST_SYS definitions from the config files.
 297         * hosts/h-amix.h, h-i386v.h:  Define POSIX_UTIME, not USG.
 298         * hosts/h-hp9000.h:  Remove USG comment.
 299         * hosts/h-rs6000.h:  Include <stdlib.h> for malloc.
 300         * hosts/h-news.h, h-sparc-64.h:  New config files that had
 301         previously been kludged in the <sysdep.h> file.
 302
 303 Thu Oct 10 17:54:08 1991  John Gilmore  (gnu at cygnus.com)
 304
 305         * config/*:  trad-core support is HOST dependent, not target
 306         dependent.  Target config files only set DEFAULT_VECTOR and/or
 307         other vector elements.  Exception:  when host-aout.c is in use,
 308         in which case we're forced to assume we're native (hp, vax,
 309         tahoe).  Rename XDEPFILES to HDEPFILES.
 310         * Makefile.in:  Rename XDEPFILES.
 311         * config/h-sun*:  Don't force static linking.
 312         * trad-core.c:  Document how to use it nowadays.
 313         * i386aout.c, newsos3.c:  Clean up.
 314         * i386coff.c:  Allow 386 coff files to be used as core files too
 315         (for reading core files from embedded systems).
 316
 317 Tue Oct  8 15:30:39 1991  John Gilmore  (gnu at cygnus.com)
 318
 319         * Add i386aout.c for a.out support on the i386.
 320
 321 Tue Oct  8 12:18:54 1991  Roland H. Pesch  (pesch at cygnus.com)
 322
 323         * reloc.c, section.c, syms.c, targets.c: correct info-node
 324         structure in *doc* comments.
 325         doc/Makefile: stop hiding complaints from makeinfo.
 326
 327 Sun Oct  6 19:10:06 1991  John Gilmore  (gnu at cygnus.com)
 328
 329         * aoutx.h (...some_aout_object_p):  Take a third parameter,
 330         the internal_exec struct, and avoid ever looking at an
 331         external_exec.  All callers changed to read the entire
 332         external_exec struct, swap and check its magic number,
 333         swap in the whole structure, and pass the swapped-in version to
 334         some_aout_object_p.
 335         * bout.c:  Bring into modern era.  Use single _object_p routine
 336         for big- aand little-endian.  Provide internal and external
 337         exec header structs.  Use separate swap-in and swap-out routines.
 338
 339         * libaout.h:  Move struct internal_exec from ../include/aout64.h
 340         to here.  Add obj_symbol_entry_size to struct aoutdata.
 341         * aoutx.h (...some_aout_object_p):  Set obj_symbol_entry_size.
 342
 343         * ../include/aout64.h:  Change EXTERNAL_LIST_SIZE to
 344         EXTERNAL_NLIST_SIZE.  Callers changed.
 345
 346 Fri Oct  4 18:18:46 1991  John Gilmore  (gnu at cygnus.com)
 347
 348         * bfd.c:  Remove strerror() to libiberty.
 349
 350         * elf.c:  Remove elf_set_section_contents, use generic one.  Lint.
 351         * libbfd-in.h, libbfd.c:  Add bfd_generic_set_section_contents.
 352         * libbfd.c (bfd_generic_{get,set}_section_contents):  Check that
 353         last byte of transfer, not first byte, is within the section.
 354
 355         * host-aout.c:  Remove `BSD' archive support.  Lint.
 356
 357         * archures.c: Rename `struct bfd_arch_info_struct' to `struct
 358         bfd_arch_info'.  Rename `typedef bfd_arch_info_struct_type' to
 359         `bfd_arch_info_type'.  All uses changed.
 360         * reloc.c:  Rename `bfd_reloc_status_enum_type' to
 361         `bfd_reloc_status_type'.  Rename `bfd_reloc_code_enum_real_type'
 362         to `bfd_reloc_code_real_type'.  (This seems to be a misnomer,
 363         it needs a better name.)  All uses changed.
 364         * targets.c:  Rename `enum target_flavour_enum' to `enum
 365         target_flavour', and remove the `_enum' from all of the enum
 366         values themselves.  All uses changed.
 367
 368         * configure.in, config/h-i386mach:  i386 mach host.
 369         * config/t-i386-aout:  Use host-aout.c.
 370
 371         * trad-core.c:  Give it its own xvec's to make it independent
 372         of other file formats.
 373         * ecoff.c, host-aout.c:  Remove refs to trad-core.
 374         * config/t-dec3100, t-hp300bsd, t-tahoe, t-vax:  Define TRAD_CORE.
 375         * targets.c:  #ifdef TRAD_CORE, include it in the vector.
 376
 377 Fri Oct  4 17:38:03 1991  Steve Chamberlain  (steve at cygnus.com)
 378
 379         * reloc.c: Extended NEWHOWTO macro
 380         * ieee.c: Changed the way 8bit pcrel is done
 381         * cpu-h8300.c: got the registers in the right order
 382
 383 Thu Oct  3 19:39:55 1991  John Gilmore  (gnu at cygnus.com)
 384
 385         * bfd-in.h:  enum boolean => enum bfd_boolean for SVR4.  Gumby's
 386         prediction is vindicated!
 387
 388         * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
 389         Remove refs to howto.c, since Steve forgot.
 390
 391 Thu Oct  3 07:49:21 1991  Steve Chamberlain  (steve at cygnus.com)
 392
 393         * elf.c: took the abort out of set_arch_mach so that objdump -i will
 394         still work. Now allows any architecture/machine to be set.
 395
 396 Wed Oct  2 13:50:35 1991  Steve Chamberlain  (steve at cygnus.com)
 397
 398         * howto.c deleted and moved code to reloc.c
 399
 400         * libbfd.h, libbfd-in.h removed $id stuff for real
 401
 402         * cpu-h8300.c Made it match various different spellings of h8300.
 403
 404         * archures.c: Took out the first char filter which made it only
 405         look for a cpu/arch match when the first chars of supplied and
 406         tested names were the same.
 407
 408         * targets.c removed oasys stuff, pending someone to fix the bugs
 409         in it.
 410
 411
 412 Tue Oct  1 12:29:44 1991  John Gilmore  (gnu at cygnus.com)
 413
 414         * Makefile.in, configure.in, targets.c, elf.c:  Add preliminary
 415         ELF support good enough for GDB.
 416         * configure.in, config/h-amix, config/t-m68k-elf:  Handle
 417         m68k-cbm-svr4 host and target.
 418         * config/t-m68k-coff, t-m88k-coff, t-m88k-aout:  Make files nonempty
 419         so `diff' and `patch' can cope.
 420
 421 Tue Oct  1 11:24:31 1991  Steve Chamberlain  (steve at cygnus.com)
 422
 423         * archures.c: removed texinfo error
 424
 425         * init.c: added texinfo hooks, and removed initialization error
 426         message.
 427
 428         * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
 429         without complaints.
 430
 431 Tue Oct  1 05:02:53 1991  John Gilmore  (gnu at cygnus.com)
 432
 433         * cpu-i960.c:  Avoid numerical count of initializers.
 434
 435         Vax Ultrix changes from David Taylor <taylor@think.com>:
 436         * host-aout.c:  Make little-endian vector really little-endian.
 437         * configure.in:  Separate vax and tahoe cases, handle ultrix.
 438         * config/t-vax:  Add trad-core.o.
 439         * config/h-vaxult:  New host system.
 440
 441 Mon Sep 30 15:13:46 1991  Steve Chamberlain  (steve at cygnus.com)
 442
 443         * bfd-in.h VERSION, change version number to 0.18, this makes a
 444         gap, but now is the same as the linker version number.
 445
 446         * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
 447         cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
 448         files will eventually contain processor specific bits for bfd,
 449         like strange relocation information and dis/assembly.  So far only
 450         the H8 has been even partially done.  This work also ties in with
 451         the change in handling architectures.
 452
 453         * amdcoff.c: (a29k_reloc) fix error message.
 454
 455         * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
 456         discover the architecture of the bfd. (sunos4_callback) calls the
 457         function bfd_set_arch_mach rather than stuffing stuff directly
 458         into the bfd. (sunos4_write_object_contents), changed names of
 459         accessor functions.
 460
 461         * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
 462         setup the environment.
 463
 464         * archive.c: (bfd_slurp_coff_armap) coff archives always have the
 465         headers in big endian format, regardless of the endianess of the
 466         host or target.
 467
 468         * archures.c: totally changed. Now an architecture is represented
 469         with a pointer to an info structure rather than an enumerated type
 470         and a long. The old info is available as two elements in the
 471         structure.  Future enhancements to architecure support will
 472         involve pointers to methods being placed into the info structure.
 473
 474         * bfd.c: changed the definition of the bfd structure for the new
 475         architecture stuff.
 476
 477         * bout.c: (b_out_set_arch_mach) changed to use the new
 478         architecture mechanism.
 479
 480         * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
 481         the new architecture mechanism.
 482
 483         * configure.in: added h8 stuff.
 484
 485         * ieee.c: too many changes to note.  Now ieee files written with
 486         bfd gas and ld can be read by gld and ieee only linkers and
 487         simulators.
 488
 489         * libbfd.c, libbfd.h: changed prototype of bfd_write.
 490
 491         * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
 492         than fixing the structure directly.
 493
 494         * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
 495         than fixing the structure directly.
 496
 497         * opncls.c: (new_bfd) makes sure that bfd_init has been called
 498         before opening a bfd.
 499
 500         * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
 501         rather than fixing the structure directly.
 502
 503         * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
 504         in the t/hmake file) a user can select which backends they want
 505         linked with bfd without changing the source.
 506
 507         * init.c: new, looks after initializing modules.
 508
 509         * howto.c: for future use, will allow an application to work out
 510         what cookie to use as a handle on a relcoatio howto.
 511
 512 Mon Sep 30 13:31:15 1991  John Gilmore  (gnu at cygnus.com)
 513
 514         * srec.c:  Better error checking, partly from Peter Schauer.
 515         (srec_object_p):  Avoid assuming any file that starts with 'S' is
 516         an S-record file!  (Check for 3 uppercase-hex digits after it.)
 517         (ISHEX):  Define new macro for checking supposedly hex characters.
 518         (pass_over):  Treat as EOF any S-record line that:
 519             *  doesn't have hex in either size character
 520             *  produces a size larger than 0x7F
 521             *  has an unrecognized type number
 522
 523 Thu Sep 26 15:27:29 1991  John Gilmore  (gnu at cygnus.com)
 524
 525         * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
 526         opncls.c:  Lint (saber actually).
 527
 528 Thu Sep 26 11:24:24 1991  Per Bothner  (bothner at cygnus.com)
 529
 530         * libaout.h (WRITE_HEADERS): Set header's a_text field always.
 531         * newsos3.c: Fixed two types: newos3 -> newsos3.
 532         * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
 533         to use correct segment.
 534
 535 Mon Sep 23 18:24:34 1991  Per Bothner  (bothner at cygnus.com)
 536
 537         * aoutx.h (print_symbol):  Handle missing symbol->name.
 538
 539 Fri Sep 20 12:26:01 1991  Stu Grossman  (grossman at cygnus.com)
 540
 541         * aoutf1.h (swapcore_sparc):  Change name of USRSTACK, fix comment
 542         at top of routine.
 543
 544 Tue Sep 17 17:23:49 1991  Stu Grossman  (grossman at cygnus.com)
 545
 546         * oasys.c, configure.in, config/h-irix3, config/t-irix3:
 547         add sgi/irix support.
 548
 549 Thu Sep 12 14:29:09 1991  John Gilmore  (gnu at cygint.cygnus.com)
 550
 551         Changes for the AMD 29000 Ultracomputer port from David Wood.

 553
 554         * opncls.c (bfd_fdopenr):  Handle NO_FCNTL.
 555
 556         * Makefile.in:  Make subdirs work by using $(INCDIR) in the
 557         crude dependencies.
 558
 559         * coffcode.h (coff_real_object_p):  Pass information about the
 560         current file's coff symbol format to BFD via the coff_data struct.
 561         (coff_find_nearest_line):  obj_icof => coff_data.
 562         (coff_swap_sym_{in,out}):  Check that SYMNMLEN == E_SYMNMLEN.
 563         (coff_swap_aux_{in,out}):  Check that FILNMLEN == E_FILNMLEN
 564         and DIMNUM == E_DIMNUM.
 565         * configure.in:  Handle a29k-*-* hosts, and targets
 566         a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
 567         * libcoff-in.h:  Add local_n_btmask, local_n_btshft,
 568         local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
 569         local_linesz to `coff_data' (tdata) struct.
 570         (coff_data, coff_data_type, coff_tdata):  Rename struct icofdata.
 571         * config/h-ultra3:  Handle a29k-*-* hosts as Ultracomputers.
 572
 573 Thu Sep 12 14:07:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 574
 575         * Makefile.in: $(MAKE) for make, $(docdir) for doc
 576         * doc/Makefile: redundant dependencies for Sun-make VPATH bug
 577
 578 Tue Sep 10 20:34:12 1991  John Gilmore  (gnu at cygint.cygnus.com)
 579
 580         * aoutf1.h (sunos4_core_file_p):  Release the right storage in
 581         error case.

 604         * aoutx.h:  Add information on host-aout.c and how to configure
 605         to use it, to the manual.
 606         * configure.in:  Tix typo.
 607         * ecoff.c:  If compiling for DEC3100, use trad_unix core files,

 615
 616         * aoutx.h, coffcode.h:  saberized.

 621         bfd.doc
 622         bfd.c, targets.c: minor rewording of doc segments
 623
 624
 625 Wed Aug 21 19:13:22 1991  John Gilmore  (gnu at cygint.cygnus.com)
 626
 627         * trad-core.c (trad_unix_core_file_p):  Use HOST_TEXT_START_ADDR,
 628         etc, rather than TEXT_START_ADDR.
 629         * host-aout.c:  Remove #if 0 around whole thing.
 630         Update to modern (32/64-bit) a.out naming conventions.
 631         Include a large chunk of ../include/a.out.gnu.h to get macros that
 632         are not defined by the system include files.
 633         (host_aout_{32,64}_write_object_contents):  Use the WRITE_HEADERS
 634         macro used by the other a.out implementations.
 635         * Makefile.in:  Give dependencies to OPTIONAL_BACKENDS.
 636
 637 Wed Aug 21 14:33:06 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

 641
 642         * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
 643         doc
 644

 648         * Makefile.in, awkscan-ip, awkscan-p, intobfd,
 649         libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
 650         libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
 651         libbfd.h, and libcoff.h; (b) in generated parts of same, use less
 652         obtrusive marks indicating .c origins.
 653
 654         * bfd.texinfo: generalize most references to linker
 655
 656 Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 657
 658         * Makefile.in: include core.p in PROTOS (building better bfd.h)
 659         * archures.c: remove empty foo() definition (crept in at vn1.9)
 660
 661 Mon Aug 19 13:48:22 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
 662
 663         * bfd.texinfo: use @setchapternewpage on instead of lots of
 664         @page's; minor rephrasing in Introduction.
 665
 666         * aoutx.h, archive.c, archures.c, bfd.c, bfd.texinfo, cache.c,
 667         coffcode.h, core.c, format.c, ieee.c, libbfd.c, libbfd.h, libcoff.h,
 668         oasys.c, opncls.c, reloc.c, section.c, syms.c, targets.c (documentation
 669         segments): used BFD (caps) more consistently as a name in
 670         discourse, fixed a few other minor typos and uses of fonts
 671
 672
 673 Thu Aug  8 16:47:43 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 674
 675         * coffcode.h: fixed bug where string table size wasn't being swapped.
 676
 677 Thu Aug  1 16:35:28 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 678
 679         * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags
 680
 681         * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT
 682         flags. (bfd_print_symbol_vandf) now knows what to do with the
 683         above flags.
 684
 685         * aoutx.h: made translate_from_native_sym_flags and
 686         translate_to_native_sym_flags produce the above flags.
 687
 688
 689 Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
 690
 691         * all files:  update copyright notices for GPL version 2.
 692         Install header comments and attribute most modules to their
 693         authors.  BFD's name is now officially "Binary File Descriptor",
 694         so remove any conflicting pejoratives.
 695         archures.h:  Consists solely of comments; remove it.
 696
 697 Fri Jul 26 18:11:34 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 698
 699         * Makefile.in, bfd.c: Made it compile again.
 700
 701 Fri Jul 19 08:17:09 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 702
 703         * newsos3.c, targets.c, coffcode.h: new patches from David Wood
 704
 705
 706 Mon Jul 15 16:27:42 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 707
 708         * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c
 709         bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on
 710         lint fixes.
 711
 712         * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
 713         29k coff by David Wood (wood@lab.ultra.nyu.edu).
 714
 715 Thu Jul  4 09:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 716
 717         * Everything: created some new files, core.c format.c, reloc.c,
 718         section.c and syms.c to split the functionality a bit better.
 719         Cleaned up the rest of the files a bit, and added some
 720         documentation.
 721
 722
 723 Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)
 724
 725         * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
 726         really takes 3 arguments, patched code and ammended prototypes.
 727
 728 Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 729
 730         * ../include/bfd.h (struct bfd_target): Added new field
 731         "align_power_min" which contains the minimum alignment for a
 732         section. This is used in coff_new_section_hook. The field
 733         insertion necessitates an update of all backends..
 734
 735         * aoutf1.h jump table field inserted
 736
 737         * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
 738         filenames too.
 739
 740         * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
 741         table field inserted.
 742
 743         * coffcode.h(just about everything) Now patches up symbol tables
 744         using a different mechanism. The Intel major bug has been fixed,
 745         and the linker can self host on the Aviion and be debugged with
 746         gdb.
 747
 748         * ecoff.c: new include and jump table patch, i386coff.c: new
 749         include and jump table patch,  icoff.c: new include and jump table
 750         patch, ieee.c: can now read archives containing ieee modules.,
 751         libcoff.h: added (combined_entry_type), libieee.h: uped max
 752         sections to 20, m68kcoff.c: new include and jump table patch,
 753         m88kbcs.c: new include and jump table patch, oasys.c: various bugs
 754         fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
 755         srec.c: jump table patch. trad-code.c fixed #IF typeo
 756
 757 Fri Jun  7 12:35:46 1991  Sean Fagan  (sef at cygint.cygnus.com)
 758
 759         * coffcode.h (coff_swap_aux_in): added else case to deal with
 760         filenames less than 9 characters.
 761
 762
 763 Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 764
 765         * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
 766
 767         * srec.c: now allows any number of sections to be created in a
 768         file. Outputs addresses of the right length.
 769
 770 Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 771
 772         * bfd.c (bfd_check_format): Fixed problem where when a defaulted
 773         target didn't match, the format got set to the attempted match,
 774         breaking a future test.
 775
 776         *../include/i386coff.h : fixed typo in type field with size
 777
 778         * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
 779         support in the jump table for the swapping routines exported to
 780         gdb. Now gdb works with the 386.
 781
 782 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 783
 784         * Merge in changes from gdb-3.95 release.
 785         Makefile.in:  Allow hmake and tmake files to add OFILES.
 786         aoutf1.h:
 787         bfd.c:  support specific targets as well as searching.  When
 788         searching, take default target in preference to others.
 789         bfd.doc:  typos
 790         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
 791         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
 792         libbfd.h:  Support specific targets as well as searching.
 793         opncls.c:  Support specific targets as well as searching.
 794         targets.c:  Search is short-circuited if default target matches.
 795         liboasys.c, libieee.c:  Undo bothner changes that make macros
 796         work to the left of assignment, but which depend on the
 797         representations of different pointer types being the same.
 798
 799 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 800
 801         * i386coff.c: created.
 802         * coffcode.h: added support for 386.
 803         * Makefile.in: added support for 386.
 804         * ../include/i386coff.h: created
 805
 806 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 807
 808         * coffcode.h: removed all put_x_<sizes>
 809         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
 810         DEFUNS
 811
 812
 813 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 814         (bothner)
 815         * opncls.c: Changed obstack_chunk_alloc use xmalloc
 816
 817 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 818
 819         * everything: Removed sysdep.h from bfd.h and put back into files
 820         from which it was split out. Now 64 bit version is built with a
 821         -DHOST_64_BIT="long long" on the compile line.
 822
 823
 824 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 825
 826         Changed all the [get|put][name] routines to use  [get|put]_[size
 827         in bytes].
 828
 829         Put in support for 64 bit work. Now two versions of bfd may be
 830         generated, according to the state of TARGET_64_BIT, one which is
 831         32 bit only, and one which is 64/32 bits.
 832         Created new back end 'demo64' to test 64 bit functionality.
 833
 834         Renamed some files to work on DOS.
 835
 836         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
 837         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
 838         chage, 64 bit transfer. * liba.out.h: Split out common code from
 839         sunos and newsos into liba.out. Name changes and prototype mods. *
 840         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
 841         prototypes for new functions. * libcoff.h: lint * libieee.h: make
 842         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
 843         change and 64bit stuff.* newsos3.c: common code removed, new jump
 844         table. * oasys.c: Name change * opncls.c: Portability fixes *
 845         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
 846         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
 847         be called b.out.c * coffcode.h: used to be called coff-code.h, now
 848         64bit ized. * demo64.c: 64 bit a.out back end
 849

 853
 854 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 855         from bothner
 856         * libieee.h: Make ieee_data and ieee_ar_data macros usable
 857         on LHS of assignment, even when using old compilers.
 858         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
 859         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
 860         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
 861         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
 862         * targets.c: Add declaration of newsos3_vec.
 863
 864
 865 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 866
 867         * aout.c: fixxed some of the problems with filepos calculation.
 868         (swap_ext_reloc): fixed problem with creation of relocs.
 869         (aout_set_section_contents): fixed filepos problem
 870
 871         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
 872         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
 873         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
 874         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
 875         cleaned up. (coff_write_object_contents) cleaned up.
 876
 877         * ecoff.c: Totally different. Now supports ecoff fully.
 878
 879         * icoff.c: fixed problems in relocation callout.
 880
 881         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 882
 883         * m68kcoff.c: updated target vector.
 884
 885         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 886         choose_reloc_size. (sunos4_write_object_contents) now calls
 887         choose_reloc_size so outputs relocs correctly, also calculates the
 888         size of the sections correctly.
 889
 890
 891
 892 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 893
 894         Merge Per Bothner's changes to modularize BFD a.out a bit.
 895
 896         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 897         * ieee.c:  Cast enums to int before comparing them, for brain-
 898         dead compilers.
 899         * coff-code.h:  Remove coff_get_section_contents, and use the
 900         generic one instead.
 901
 902         * aout.c:  Derive new module from sunos.c, containing generic
 903         support code for all kinds of a.out files.
 904
 905         * sunos.c: Remove all code that goes in aout.c.  Split out
 906         machine dependent followup in sunos4_object_p into
 907         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 908         and redefine only the names we CHANGE, not all the names.  Drop
 909         the little-endian vector, and rename the vector as sunos4 rather
 910         than generic.
 911
 912         * b.out.c:  Use aout.c routines for most of the work.  Slight
 913         changes for the new regime.  Remove close_and_cleanup and
 914         get_section_contents in favor of generics.  New transfer vector
 915         regime.
 916
 917         * newsos.c:  New support for Sony NEWS, another a.out format.
 918
 919         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 920         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 921         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 922         to tvec.
 923         * opncls.c (bfd_close):  Call format-dependent write_contents
 924         routine, if writing, before calling target-dependent
 925         close_and_cleanup routine (which is now always generic, I think).
 926         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 927         close_and_cleanup and move code from it to
 928         srec_write_object_contents.  Add write_contents to tvec.
 929         * targets.c:  Remove a.out little vector, replace a.out big
 930         vector with SunOS vector.  FIXME:  Need Vax support again now.
 931
 932         * libbfd.h:  Add write_contents format-dependent-vector to the
 933         bfd_target vector.  Supply a generic close_and_cleanup routine.
 934         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 935         all routines defined in aout.c.  Rename "sunos" things to "aout"
 936         things.  Add a few fields where needed for various formats.
 937         * Makefile.in:  Add aout.c and newsos.c.
 938
 939         * archive.c, ieee.c, oasys.c:  Lint.
 940
 941 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 942
 943         * ../include/bfd.h
 944         changed forward declaration struct stat; to reduce warnings. Changed
 945         comment on bfd_h_<x>_x.
 946
 947         * ../include/m68kcoff.h, ../include/intel-coff.h,
 948         ../include/m88k-bcs.h
 949         Now there are two incarnations of relocs, linenos and syments. One for
 950         internal digestion, and one full of char arrays for I/O. The original
 951         names have gone to detect errors.
 952
 953         * Makefile.in, m68kcoff.c, targets.c
 954         Test new structure code with a 68k coff implementaion
 955
 956         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 957         Fixed all the places where there were problems with the size and
 958         alignments of structures on disk and structures in memory. #ifed out
 959         all the code in coffswap.c, since it should be done using the target
 960         swap routines now.
 961
 962 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 963
 964         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 965         multiple reloc command.
 966
 967         * sunos.c (sunos4_set_section_contents): Made it so that sections
 968         are always padded to their alignment size.
 969
 970 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 971
 972         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 973         Clean up types and such (saber C problems).
 974         * ecoff.c:  Clean up types and such.  Remove routines that are
 975         not used.  Fix up reading and swapping of shorts from files.
 976
 977    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 978
 979         * a.out.vax.c: Remove two bogus "static" from prototypes.
 980
 981         * ecoff.c: Got rid of lots of non-working junk (that had
 982         been copied directly from coff-code.h).
 983         Updated to be consistent with updates to icoff.c and coff-code.h.
 984
 985         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 986         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 987
 988         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 989         but until the target_vector is automatically generated,
 990         it's as good as any. Note that the text offset is the only
 991         difference between NewsOS and SunOs (including magic numbers).
 992         (Most of the sunos_* routines should to renamed bsd_*
 993         and move to a bsd.c file. Then (and when the target_vector
 994         is automatically generated) it might make sense to create
 995         a separate Sony target.)
 996
 997         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 998         on some systems, and doesn't help on others.
 999         Similarly, only define X_OK if not already defined.
1000
1001         * trad-core.c: Don't include sys/stat.h - at least
1002         on NewsOS 3, it has already been included.
1003
1004 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
1005
1006         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1007         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
1008         symbol tables if necessary when reading them in, so gdb can use
1009         them.  Add "bfd_coff_" to the names so they won't conflict with
1010         names in calling programs.  FIXME-soon:  if coff-code.h is
1011         included in two BFD modules, this will cause duplicate
1012         definitions; the routines should be exported to a separate,
1013         common, module (probably along with a mess of other ones).
1014
1015 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
1016
1017         Improve modtime support.
1018
1019         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
1020         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
1021         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
1022         BUG:  archive members still do not get correct mod times.
1023
1024         Improve floating point support for core files.
1025
1026         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
1027         (sunos4_core_file_p):  Create a second registers section in the
1028         core file, called ".reg2", for the float registers.
1029
1030 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
1031
1032         * many changes to improve archive handling; found a logic flaw in
1033           bfd_check_format which only just happened to work by cooncidence.
1034
1035 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
1036
1037         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1038         correctly.
1039
1040         * bfd.h: changed type of udata in asymbol to void *, like it
1041         should be. Added bfd_reloc_dangerous enum member.
1042
1043         * coff-code.h: Fixed it so that internally generated symbols get
1044         their values relocated correctly in all cases. Removed calls to
1045         xmalloc.
1046
1047         * icoff.c: Not understanding the destination symbol of a reloc is
1048         not a failure any more, just 'dangerous'. This allows linking of
1049         b.out and coff images.
1050
1051         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1052         calculated.
1053
1054
1055 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
1056
1057         * sunos.c (translate_to_native_sym_flags): fixed
1058         sym_pointer->n_value so that symbols on the way out get their
1059         section relative values calculated correctly.
1060
1061         * coff-code.h (mangle_symbols): fixed problem where tags were not
1062         being relocated for structs, enums, unions. Also various lints.
1063
1064 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
1065
1066         * archive.c (get_elt_at_filepos): system_call_error returned
1067           incorrectly.
1068
1069 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
1070
1071         * Resolve the use of no_error and system_call_error.
1072           The bfd library itself now will never set bfd_error to
1073           no_error.
1074
1075           The code still needs to be combed to make sure all the error
1076           codes are correct.  I suspect they are not always set correctly.
1077
1078         * The names of all the messages have _ prepended because the sun
1079           bundled compiler can't distinguish from a macro which takes an
1080           argument and the same identifier in a non-macro context.
1081
1082         * The reason for the above being that entry points which used to
1083           be trampoline functions are now just macros which expand to a
1084           direct call through the bfd's xfer vector.
1085
1086         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
1087           must gas have its own version of everything (the gas version
1088           had the correct value)
1089
1090 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
1091
1092         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1093         properly support i960 architecture and output correct reloc stuff.
1094
1095         * bfd.h: added prototype for bfd_printable_arch_mach, added
1096         BFD_FAIL
1097
1098         * coff-code.h: Applied patches from chrisb to support i960
1099         architecture, zero relocs and swap them correcly and conditionally
1100         compiled the timestamp.
1101
1102         * sunos.c: Made the default section alignment 2^3 so that doubles
1103         are done properly. Fixed the same reloc bug that was in b.out.c
1104
1105         * sysdep.h: Now compiles on a Posix box
1106
1107 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
1108
1109         * icoff.c:  Fix comment on big-endian version.
1110         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
1111         F_RELFLG).  Set F_AR32WR in output files if little endian
1112         architecture.
1113
1114 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1115
1116         * archures.c fixed =/== typo
1117
1118         * sunos.c added architecture stuff for output. Fixed
1119         bug where files where vma(data) != size(text)
1120         were processed wrong.
1121
1122         * coff-code.h added a lint cast
1123
1124         * (../include/a.out.sun4.h) fixed it so zmagic
1125         worked
1126
1127 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1128
1129         * archive.c removed loads of includes, and fixed bug where string
1130         table didn't have a null at the end.
1131
1132         * bfd.c fixed includes, added symbols argument to
1133         canonicalize_reloc entry point.
1134
1135         * libbfd.c fixed includes and added some lint patches.
1136
1137         * targets.c added both sorts of intel coff.
1138
1139         * b.out.c fixed included, changed was the canonical
1140         relocs were done.
1141
1142         * icoff.c added support for callj and big and little
1143         enidian tables.
1144
1145         * opncls.c added chmod+xing for files with EXEC_P set.
1146
1147         * sunos.c fixed includes. Changed default section
1148         alignement to words. Fixed relocation stuff to work with
1149         new scheme
1150
1151         * bfd.h various new types added, prototype for new
1152         reloc calls, changed bfd->iostream to a void *
1153         to including files don't need stdio.h.
1154
1155         * libcoff.h added conversion table to tie relocs to
1156         canonical symbols
1157
1158         * sysdep.h created
1159
1160         * coff-code.h fixed includes. Added code to support
1161         big and little endian formats. Various lints. Better
1162         processing of symbols. Changed reloc stuff to new
1163         order
1164
1165         * libbfd.h fixed includes
1166
1167
1168 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1169
1170         * bfd.h changed name of alignment entry in sec_struct to
1171         alignment_power, because of conflicting uses within bfd.
1172         Now it should be obvious that it's a 2**n alignment
1173         specifier. Removed start_pad, end_alignment, block, minsize,
1174         output_file_alignment, subsection_alignment and original_vma fields.
1175         Added align_power() macro. Fixed bfd_section_alignment
1176         acessor macros. Added bfd_symbol_same_target macro.
1177
1178         * b.out.c (b_out_write_object_contents) fixed to use
1179         new alignment member. Fixed (callj_callback) to use section
1180         relative symbols properly.
1181
1182         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1183         Fixed (translate_from_native_sym_flags) to correctly make
1184         symbols section relative.
1185
1186         * bfd.c (bfd_errmsg) fixed various enum cast problems.
1187         (bfd_make_section) took out initialization of obsolete members.
1188         (bfd_print_symbol_vandf) added
1189
1190         * opncls.c (bfd_create) created.
1191
1192         * coff-code.h (coff_new_section_hook) took away refs
1193         to obsolete members. (make_a_section_from_file) added
1194         conversion between alignment types. (coff_symbol_from)
1195         added. (coff_count_linenumbers) only counts linenumbers
1196         if symbol is of coff-type. (coff_mangle_symbols) only
1197         heavily mangles symbols if symbol is coff-type.
1198         (coff_write_symbols) various lints. (coff_write_object_contents)
1199         various lints and modification for alignment conversion.
1200         (coff_slurp_relocs) fixed for use with new asection shape.
1201
1202 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1203
1204         * archive.c lots of lint
1205
1206         * b.out.c added callj relocation support, upgrated reloc howto.
1207         Fixed so that asymbol and reloc records are output
1208         correctly.
1209
1210         * bfd.c lots of lint, support for new bfd entry point
1211         bfd_print_symbol.
1212
1213         * bfd.h changed definition of asymbol to contain pointer to
1214         owning bfd, removed target dependencies.
1215
1216         * cache.c took out print statements, put in BFD_ASSERT calls.
1217
1218         * coff-code.h various lints, corrected linenumber output
1219         functionality. Added support for new style asymbols and
1220         bfd_print_symbol. Fixed so that asymbol and
1221         reloc records are handled correctly. Added timestamp.
1222
1223         * icoff.c Added support for new howto shape.
1224
1225         * liba.out.h Added support for new asymbol shape
1226
1227         * libbfd.c various lints
1228
1229         * libbfd.h various lints
1230
1231         * libcoff.h added support for new asymbol shape.
1232
1233         * sunos.c  various lints. Added support for new asymbol shape
1234         and bfd_print_symbol.
1235
1236 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1237
1238         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1239         pointer lint. Added support for callj relocation. Fixed bug where
1240         the last 32 bytes of the text section were overwritten by data. Fixed bug
1241         where archives of b.out didn't work due bfd_slurp_extended_name_table
1242         returning false.
1243
1244         * sunos.c added support for n_other field. Braced the howto table so
1245         that it won't be affected by any lengthing of the howto struct typedef.
1246         Various lints
1247
1248         * bfd.h added support for n_other field, added special_function
1249         reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
1250         macros.
1251
1252         * bfd.c upgraded bfd_perform_relocation, various lints.
1253
1254 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
1255
1256         * ChangeLog:  Started ChangeLog for BFD.
1257         * ToDo:  Create file for suggestions.
1258
1259         * Makefile:  Support easy loading into Saber C.
1260         Add dependencies for icoff.o and bcs88kcoff.o.
1261         Rename coff.c to coff-code.h.  Change callers.
1262
1263         * bfd.c (bfd_check_format):  Allow the check_format routines
1264         to return the desired target vector, rather than just a Boolean.
1265         bfd.h (bfd_check_format):  Change function pointer return type.
1266         archive.c (bfd_generic_archive_p):  change callee.
1267         b.out.c (b_out_little_object_p, b_out_big_object_p,
1268         b_out_real_object_p):  change callee.
1269         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
1270         in check_format transfer vectors that need a filler.
1271         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
1272         bcs88kcoff.c:  change callee.
1273         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
1274         icoff.c:  change callee.
1275         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
1276
1277         * libbfd.c (zalloc):  It should actually zero the storage!
1278         This was commented out for some reason.
1279
1280         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
1281         This is so callers can avoid <stdlib.h> which doesn't exist
1282         on older systems.
1283
1284         * bfd.c (map_over_sections):  Add debugging code, since I
1285         noticed the section count for sunos core files was bad, but only
1286         GDB had detected the problem.
1287         (bfd_set_section_lineno_size, bfd_set_section_linenos,
1288         bfd_get_section_linenos):  Remove obsolete functions.
1289         (bfd_apply_relocations):  Use longs, not ints, for the math.
1290
1291         * bfd.h:  Declare enum boolean and struct bfd_target as well
1292         as typedefs for them.  Remove obsolete
1293         bfd_get_section_lineno_size.
1294
1295         * cache.c:  Make the "fdopen" support work.  Keep better track
1296         of how many files are open.  Centralize the opening of files
1297         and be sure bfd_open[rw] actually try to open the file.  Evade
1298         linked list initialization problems.
1299
1300         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
1301
1302         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
1303
1304         * cplus-dem.c:  Delete file, since it is not part of BFD.
1305
1306         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
1307         (bfd_openr, bfd_openw):  Actually open the file, give error now.
1308
1309         * sunos.c (sunos4_core_file_p):  Set section count.
1310         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
1311         obsolete definitions.
1312         (_write_symbol_table):  Initialize <idx> counter.
1313         (foop):  Eliminate debugging code.
1314
1315
1316
1317
