   3 * The addr2line, c++filt, nm and objdump tools now have a limit on the
   4   maximum amount of recursion that is allowed whilst demangling strings.
   5   The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
   6   constant declared in the include/demangle.h header file.  At the time
   7   of writing this constant has the value of 2048.
   8
   9   The --no-recurse-limit option can be used to remove the limit, restoring
  10   the behaviour of earlier versions of these tools.  This may be needed in
  11   order to dmangle truly complicated names, but it also leaves the tools
  12   vulnerable to stack exhaustion from maliciously constructed mangled names.
  13
  14 * Objdump's --disassemble option can now take a parameter, specifying the
  15   starting symbol for disassembly.  Disassembly will continue from this
  16   symbol up to the next symbol or the end of the function.
  17
  18 * The MIPS port now supports the Loongson 2K1000 processor which implements
  19   the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE,
  20   Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for
  21   Loongson 2K1000 processor.
  22
  23 * The MIPS port now supports the Loongson 3A2000/3A3000 processor which
  24   implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE,
  25   Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e
  26   option for Loongson 3A2000/3A3000 processor.
  27
  28 * The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a,
  29   which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE
  30   and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson
  31   3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
  32   compatibility.
  33
  34 Changes in 2.31:
  35
  36 * Add support for disassembling netronome Flow Processor (NFP) firmware files.
  37
  38 * The AArch64 port now supports showing disassembly notes which are emitted
  39   when inconsistencies are found with the instruction that may result in the
  40   instruction being invalid.  These can be turned on with the option -M notes
  41   to objdump.
  42
  43 * The AArch64 port now emits warnings when a combination of an instruction and
  44   a named register could be invalid.
  45
  46 * Added O modifier to ar to display member offsets inside an archive
  47
  48 Changes in 2.30:
  49
  50 * Add --debug-dump=links option to readelf and --dwarf=links option to objdump
  51   which displays the contents of any .gnu_debuglink or .gnu_debugaltlink
  52   sections.
  53
  54   Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links
  55   option to objdump which causes indirect links into separate debug info files
  56   to be followed when dumping other DWARF sections.
  57
  58 Changes in 2.29:
  59
  60 * The MIPS port now supports microMIPS eXtended Physical Addressing (XPA)
  61   instructions for assembly and disassembly.
  62
  63 * The MIPS port now supports the microMIPS Release 5 ISA for assembly and
  64   disassembly.
  65
  66 * The MIPS port now supports the Imagination interAptiv MR2 processor,
  67   which implements the MIPS32r3 ISA, the MIPS16e2 ASE as well as a couple
  68   of implementation-specific regular MIPS and MIPS16e2 ASE instructions.
  69
  70 * The SPARC port now supports the SPARC M8 processor, which implements the
  71   Oracle SPARC Architecture 2017.
  72
  73 * The MIPS port now supports the MIPS16e2 ASE for assembly and disassembly.
  74
  75 * Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
  76
  77 * Add support for the wasm32 ELF conversion of the WebAssembly file format.
  78
  79 * Add --inlines option to objdump, which extends the --line-numbers option
  80   so that inlined functions will display their nesting information.
  81
  82 * Add --merge-notes options to objcopy to reduce the size of notes in
  83   a binary file by merging and deleting redundant notes.
  84
  85 * Add support for locating separate debug info files using the build-id
  86   method, where the separate file has a name based upon the build-id of
  87   the original file.
  88
  89 Changes in 2.28:
  90
  91 * This version of binutils fixes a problem with PowerPC VLE 16A and 16D
  92   relocations which were functionally swapped, for example,
  93   R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
  94   performed like R_PPC_VLE_HA16A.  This could have been fixed by
  95   renumbering relocations, which would keep object files created by an
  96   older version of gas compatible with a newer ld.  However, that would
  97   require an ABI update, affecting other assemblers and linkers that
  98   create and process the relocations correctly.  It is recommended that
  99   all VLE object files be recompiled, but ld can modify the relocations
 100   if --vle-reloc-fixup is passed to ld.  If the new ld command-line
 101   option is not used, ld will ld warn on finding relocations inconsistent
 102   with the instructions being relocated.
 103
 104 * The nm program has a new command-line option (--with-version-strings)
 105   which will display a symbol's version information, if any, after the
 106   symbol's name.
 107
 108 * The ARC port of objdump now accepts a -M option to specify the extra
 109   instruction class(es) that should be disassembled.
 110
 111 * The --remove-section option for objcopy and strip now accepts section
 112   patterns starting with an exclamation point to indicate a non-matching
 113   section.  A non-matching section is removed from the set of sections
 114   matched by an earlier --remove-section pattern.
 115
 116 * The --only-section option for objcopy now accepts section patterns
 117   starting with an exclamation point to indicate a non-matching section.
 118   A non-matching section is removed from the set of sections matched by
 119   an earlier --only-section pattern.
 120
 121 * New --remove-relocations=SECTIONPATTERN option for objcopy and strip.
 122   This option can be used to remove sections containing relocations.
 123   The SECTIONPATTERN is the section to which the relocations apply, not
 124   the relocation section itself.
 125
 126 Changes in 2.27:
 127
 128 * Add a configure option, --enable-64-bit-archive, to force use of a
 129   64-bit format when creating an archive symbol index.
 130
 131 * Add --elf-stt-common= option to objcopy for ELF targets to control
 132   whether to convert common symbols to the STT_COMMON type.
 133
 134 Changes in 2.26:
 135
 136 * Add option to objcopy to insert new symbols into a file:
 137   --add-symbol <name>=[<section>:]<value>[,<flags>]
 138
 139 * Add support for the ARC EM/HS, and ARC600/700 architectures.
 140
 141 * Extend objcopy --compress-debug-sections option to support
 142   --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
 143   targets.
 144
 145 * Add --update-section option to objcopy.
 146
 147 * Add --output-separator option to strings.
 148
 149 Changes in 2.25:
 150
 151 * Add --data option to strings to only print strings in loadable, initialized
 152   data sections.  Change the default behaviour to be --all, but add a new
 153   configure time option of --disable-default-strings-all to restore the old
 154   default behaviour.
 155
 156 * Add --include-all-whitespace to strings.
 157
 158 * Add --dump-section option to objcopy.
 159
 160 * Add support for the Andes NDS32.
 161
 162 Changes in 2.24:
 163
 164 * Objcopy now supports wildcard characters in command-line options that take
 165   section names.
 166
 167 * Add support for Altera Nios II.
 168
 169 Changes in 2.23:
 170
 171 * Add support for the VLE extension to the PowerPC architecture.
 172
 173 * Add support for x64 Windows target of the delayed-load-library.
 174
 175 * Add support for the Renesas RL78 architecture.
 176
 177 Changes in 2.22:
 178
 179 * Add support for displaying the contents of .debug.macro sections.
 180
 181 * Add --preprocessor-arg option to windres to specify additional options
 182   passed to preprocessor.
 183
 184 * Add --dwarf-start and --dwarf-end to readelf and objdump.  These are used by
 185   the new Emacs mode, see dwarf-mode.el.
 186
 187 * Add support for the Tilera TILEPro and TILE-Gx architectures.
 188
 189 changes in 2.21:
 190
 191 * Add --interleave-width option to objcopy to allowing copying a range of
 192   bytes from the input to the output with the --interleave option.
 193
 194 * Add support for the TMS320C6000 (TI C6X) processor family.
 195
 196 * Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using
 197   the -u / --unwind option.
 198
 199 * Add --dyn-syms to readelf to dump dynamic symbol table.
 200
 201 * A new tool - elfedit - has been added to directly manipulate ELF format
 202   binaries.
 203
 204 * Add to dlltool .def file feature of aliasing PE internal symbol name by
 205   '== <ID>' option.
 206
 207 * Add a new command-line option -a / --addresses to addr2line to display the
 208   address before function name or source filename.
 209
 210 * Add a new command-line option -p / --pretty-print to addr2line to have
 211   a more human readable output.
 212
 213 * The hppa/som targets can now be compiled on any host.
 214
 215 Changes in 2.20:
 216
 217 * Add support for delay importing to dlltool.  Use the --output-delaylib <file>
 218   switch to create a delay-import library.  The resulting app will load the dll
 219   as soon as the first function is called.  It will link to __delayLoadHelper2()
 220   from the static delayimp library, which will import LoadLibraryA and
 221   GetProcAddress from kernel32.
 222
 223 * Add a new command-line option, --insn-width=WIDTH, to objdump to specify
 224   number of bytes to be displayed on a single line when disassembling
 225   instructions.
 226
 227 * Readelf can now display the relocated contents of a section as a sequence
 228   of bytes via the --relocated-dump=<name|number> command-line option.
 229
 230 * The gprof program has been given a new command-line option:
 231   --external-symbols-table=<filename> which reads in symbols from a specified
 232   file.
 233
 234 * The plugin target has been added to bfd. It can load the same shared objects
 235   used by gold and uses them to provide basic support for new file formats.
 236
 237 * The verilog memory hex dump file format is now supported as an output format
 238   for objcopy.
 239
 240 * Add --file-alignment, --heap, --image-base, --section-alignment,
 241   --stack and --subsystem command-line options to objcopy, which will
 242   set PE optional header.
 243
 244 * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w.
 245
 246 * --as-needed now links in a dynamic library if it satisfies undefined
 247   symbols in regular objects, or in other dynamic libraries.  In the
 248   latter case the library is not linked if it is found in a DT_NEEDED
 249   entry of one of the libraries already linked.
 250
 251 * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to
 252   add absolute paths for -S.
 253
 254 * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall-
 255   back to old import table generation with null element prefix.
 256
 257 * Added --identify-strict switch to cause --identify <implib> to
 258   report an error when the import library is associated with
 259   multiple DLLs.
 260
 261 * Added --identify <implib> option to dlltool, which determines the
 262   name of the DLL associated with the specified <implib>.
 263
 264 * Support for PowerPC booke64 instructions has been removed.  The assembler no
 265   longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts
 266   -Mbooke32 or -Mbooke64.  Instead, -mbooke and -Mbooke should be used.
 267
 268 Changes in 2.19:
 269
 270 * Added -wL switch to dump decoded contents of .debug_line.
 271
 272 * Added support for "thin" archives which contain pathnames pointing to
 273   object files rather than the files themselves and which contain a
 274   flattened symbol index for all objects, and archives, which have been
 275   added to the archive.
 276
 277 * Added -F switch to objdump to include file offsets in the disassembly.
 278
 279 * Added -c switch to readelf to allow string dumps of archive symbol index.
 280
 281 * Support for SSE5 has been added to the i386 port.
 282
 283 * Added -p switch to readelf to allow string dumps of sections.
 284
 285 Changes in 2.18:
 286
 287 * Resolved 37 coding problems in bfd including static array overruns, null
 288   pointer dereferences and use of a malloc buffer after it has been freed, as
 289   revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com).
 290
 291 * The binutils sources are now released under version 3 of the GNU General
 292   Public License.
 293
 294 * A new tool "windmc" has been added for some targets.  This is a message
 295   compiler which attempts to be compatible with the MS version.
 296
 297 * Add codepage support to the windres tool.  It now supports many new
 298   resource types (e.g. MANIFEST, TOOLBAR, etc).  The output generation
 299   for binary files is done now via bfd itself.  The endianess problems
 300   for different hosts are solved.  Dumps of .res files can now be
 301   re-compiled by windres without lossing resources or compilation errors.
 302   Some problems on dialog resource translations are corrected.
 303
 304 * Add --extract-symbol command-line option to objcopy, which will
 305   strip everything out of an ordinary object file or executable except
 306   for its symbol table.  Files containing just symbols can be useful
 307   to some OSes.
 308
 309 Changes in 2.17:
 310
 311 * Add "-x NAME" to readelf in addition to "-x NUMBER".
 312
 313 * Add -i and -t switches to cxxfilt.  -i disables the display of implementation
 314   specific extra demangling information (if any) and -t disables the demangling
 315   of types.
 316
 317 * Add support for the "@<file>" syntax to the command lines of all tools, so
 318   that extra switches can be read from <file>.
 319
 320 * Add "-W/--dwarf" to objdump to display the contents of the DWARF
 321   debug sections.
 322
 323 * Add "-t/--section-details" to readelf to display section details.
 324   "-N/--full-section-name" is deprecated.
 325
 326 * powerpc-linux ld now supports a variant form of PLT and GOT for the security
 327   conscious.  This form will automatically be chosen when ld detects that all
 328   code in regular object files was generated by gcc -msecure-plt.  The old PLT
 329   and GOT may be forced by a new ld option, --bss-plt.
 330
 331 * Add "-i/--inlines" to addr2line to print enclosing scope information
 332   for inlined function chains, back to first non-inlined function.
 333
 334 * Add "-N/--full-section-name" to readelf to display full section name.
 335
 336 * Add "-M entry:<addr>" switch to objdump to specify a function entry address
 337   when disassembling VAX binaries.
 338
 339 * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches
 340   to objcopy to convert local symbols into global symbols.
 341
 342 * gprof now allows input files to have histogram records for
 343   several memory ranges, provided those ranges are disjoint.
 344
 345 Changes in 2.16:
 346
 347 * Add "-g/--section-groups" to readelf to display section groups.
 348
 349 * objcopy recognizes two new options --strip-unneeded-symbol and
 350   --strip-unneeded-symbols, namely for use together with the wildcard
 351   matching the original --strip-symbol/--strip-symbols provided, but
 352   retaining any symbols matching but needed by relocations.
 353
 354 * readelf can now display address ranges from .debug_range sections.  This
 355   happens automatically when a DW_AT_range attribute is encountered.  The
 356   command-line switch --debug-dump=Ranges (or -wR) can also be used to display
 357   the contents of the .debug_range section.
 358
 359 * nm and objdump now have a switch "--special-syms" to enable the displaying of
 360   symbols which the target considers to be special.  By default these symbols
 361   are no longer displayed.  Currently the only special symbols are the Mapping
 362   symbols used by the ARM port to mark transitions between text and data and
 363   between ARM and THUMB code.
 364
 365 * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional
 366   import and export symbols with <preifx> prepended to them.
 367
 368 Changes in 2.15:
 369
 370 * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
 371   disassembler to print the "raw" mips instruction mnemonic instead of some
 372   pseudo instruction name.  I.E. print "daddu" or "or" instead of "move",
 373   "sll" instead of "nop", etc.
 374
 375 * objcopy and strip can now take wildcard patterns in symbol names specified on
 376   the command line provided that the --wildcard switch is used to enable them.
 377
 378 * readelf can now parse archives.
 379
 380 * objdump now accepts --debugging-tags to print the debug information in a
 381   format compatible with ctags tool.
 382
 383 * objcopy and strip now accept --only-keep-debug to create a file containing
 384   those sections that would be stripped out by --strip-debug.  The idea is that
 385   this can be used in conjunction with the --add-gnu-debuglink switch to create
 386   a two part program distribution - one a stripped executable and the other the
 387   debugging info.
 388
 389 * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink
 390   section into a (presumably stripped) executable.  This allows the debug
 391   information for the file to be held in a separate file.
 392
 393 * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
 394   single-character representation.  This can be checked by running nm
 395   with the -a switch.
 396
 397 Changes in 2.14:
 398
 399 * Added --info switch to objcopy and strip.
 400
 401 * Support for Vitesse IQ2000 added by Red Hat.
 402
 403 * Added 'S' encoding to strings to allow the display of 8-bit characters.
 404
 405 * Added --prefix-symbols=<text>, --prefix-sections=<text> and
 406   --prefix-alloc-sections=<text> to objcopy.
 407
 408 * readelf can handle the extensions to the DWARF2 spec used by the Unified
 409   Parallel C compiler.
 410
 411 * BFD no longer declares a "boolean" type, to avoid clashes with other
 412   headers that declare the same.  Users of BFD should replace boolean,
 413   false and true, with int, 0 and 1, or define their own boolean type.
 414
 415 * Support for IP2K added by Denis Chertykov.
 416
 417 Changes in 2.13:
 418
 419 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 420   and FR500 included.
 421
 422 Changes in version 2.12:
 423
 424 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 425
 426 * size: Add --totals to display summary of sizes (Berkeley format only).
 427
 428 * readelf: Add --wide option to not break section header or segment listing
 429   lines to fit into 80 columns.
 430
 431 * strings: Add --encoding to display wide character strings.  By Markus Kuhn.
 432
 433 * objcopy: Add --rename-section to change section names.
 434
 435 * readelf: Support added for DWARF 2.1 extensions.  Support added for
 436   displaying the contents of .debug.macinfo sections.
 437
 438 * New command-line switches added to objcopy to allow symbols to be kept as
 439   global symbols, and also to specify files containing lists of such symbols.
 440   by Honda Hiroki.
 441
 442 * Support for OpenRISC by Johan Rydberg.
 443
 444 * New command-line switch to objcopy --alt-machine-code which creates a binary
 445   with an alternate machine code if one is defined in the architecture
 446   description.  Only supported for ELF targets.  By Alexandre Oliva.
 447
 448 * New command-line switch to objcopy -B (or --binary-architecture) which sets
 449   the architecture of the output file to the given argument.  This option only
 450   makes sense, if the input target is binary.  Otherwise it is ignored.
 451   By Stefan Geuken.
 452
 453 * Support for PDP-11 by Lars Brinkhoff.
 454
 455 Changes in binutils 2.11:
 456
 457 * Add support for ARM v5t and v5te architectures and Intel's XScale ARM
 458   extenstions.
 459
 460 * Add --srec-len and --srec-forceS3 command-line switch to objcopy.
 461   By Luciano Gemme.
 462
 463 * Support for the MIPS32, by Anders Norlander.
 464
 465 * Support for the i860, by Jason Eckhardt.
 466
 467 * Support for CRIS (Axis Communications ETRAX series).
 468
 469 Changes in binutils 2.10:
 470
 471 * Support for 64-bit ELF on HPPA.
 472
 473 * New command-line switch to objdump --file-start-context which shows the
 474   entire file contents up to the source line first encountered for a given
 475   file.
 476
 477 * New command-line switch to objdump -M (or --disassembler-options) which takes
 478   a parameter which can then be interpreted on a per-target basis by the
 479   disassembler.  Used by ARM targets to select register name sets, ISA, APCS or
 480   raw verions.
 481
 482 * objdump support for -mi386:intel which causes disassembly to be displayed
 483   with intel syntax.
 484
 485 * New program: readelf.  This displays the contents of ELF format files,
 486   regardless of target machine.
 487
 488 * objcopy now takes --change-section-lma, --change-section-vma, and
 489   --change-section-address options.  The old --adjust-section-vma option is
 490   equivalent to --change-section-address.  The other --adjust-* options are now
 491   renamed to --change-*, although --adjust-* continues to work.
 492
 493 * objcopy has a --redefine-sym option that lets you rename symbols.
 494
 495 * objcopy now takes a -j/--only-section option to copy only the specified
 496   sections.
 497
 498 * dlltool now supports the IMPORTS command.
 499
 500 * dlltool now takes --export-all-symbols, --no-export-all-symbols,
 501   --exclude-symbols, and --no-default-excludes options.
 502
 503 Changes in binutils 2.9:
 504
 505 * Added windres program, which can be used to manipulate resources in WIN32
 506   files as used on Windows 95 and Windows NT.
 507
 508 * The objcopy --gap-fill and --pad-to options operate on the LMA rather than
 509   the VMA of the sections.
 510
 511 * Added S modifier to ar to not build a symbol table.
 512
 513 Changes in binutils 2.8:
 514
 515 * The objdump disassembly format has been changed, and hopefully improved.  Use
 516   the new --prefix-addresses option to get the old format.  There are also new
 517   --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
 518   output.
 519
 520 * Formats may now be specified as configuration triplets.  For example,
 521   objdump -b i386-pc-linux.  The triplets are not passed through config.sub,
 522   so they must be in canonical form.
 523
 524 * Added new addr2line program.  This uses the debugging information to convert
 525   an address into a file name and line number within a program.
 526
 527 * Added --change-leading-char argument to objcopy.
 528
 529 * Added --weaken argument to objcopy.
 530
 531 * objdump --dynamic-reloc now works on ELF executables and shared libraries.
 532
 533 * Added --adjust-vma option to objdump.
 534
 535 * Added -C/--demangle option to objdump.
 536
 537 * Added -p/--preserve-dates option to strip and objcopy.
 538
 539 Changes in binutils 2.7:
 540
 541 * Added --enable-shared and --enable-commonbfdlib options to configure.
 542
 543 * Added --debugging argument to objdump and objcopy.
 544
 545 * Added --defined-only argument to nm.
 546
 547 * Added --remove-leading-char argument to objcopy.
 548
 549 * The objdump --line-numbers option is now meaningful with --reloc.
 550
 551 * Added --line-numbers option to nm.
 552
 553 * Added --endian/-EB/-EL option to objdump.
 554
 555 * Added support for Alpha OpenVMS/AXP.
 556
 557 Changes in binutils 2.6:
 558
 559 * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
 560
 561 * Added several arguments to objcopy to provide some control over how the new
 562   file is laid out in memory.  Also added binary output format to BFD to permit
 563   generating plain binary files.
 564
 565 * Added --start-address and --stop-address options to objdump.
 566
 567 * ar and ranlib now work on AIX.  The tools are now built by default on AIX.
 568
 569 Changes in binutils 2.5:
 570
 571 * Changed objdump -dr to dump the relocs interspersed with the assembly
 572   listing, for a more useful listing of relocatable files.
 573
 574 * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
 575   Added -D/--disassemble-all option to disassemble all sections.
 576
 577 * Added --size-sort option to nm.
 578
 579 * strip and objcopy should now be able to handle dynamically linked ELF
 580   executables.
 581
 582 Changes in binutils 2.4:
 583
 584 * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
 585   PowerPC (except ar and ranlib; by Ian Taylor).
 586
 587 * Support for Irix 5.
 588
 589 * Programs `strip' and `objcopy' will not attempt to write dynamically linked
 590   ELF output files, since BFD currently can't create them properly.
 591
 592 Changes in binutils 2.3:
 593
 594 * A new --stabs argument has been added to objdump to dump stabs sections in
 595   ELF and COFF files.
 596
 597 * A new program, nlmconv, has been added.  It can convert object files into
 598   Novell NetWare Loadable Modules.
 599
 600 * The strings program has been added.
 601
 602 Changes in binutils 2.2:
 603
 604 * The 'copy' program has been renamed to 'objcopy', for consistency with
 605   'objdump', and because 'copy' might more plausibly be used as a synonym for
 606   'cp'.
 607
 608 * The new stand-alone program c++filt is a filter that converts encoded
 609   (mangled) C++ assembly-level identifiers to user-level names.  (Note: This
 610   may get moved to the gcc distribution.)
 611
 612 * nm -o on an archive now prefixes each line with the archive name, matching
 613   the output from BSD nm.
 614
 615 * ar (and ld) can now read (but not write) BSD4.4-style archives.
 616
 617 * New support for H8500, Z8000, and the Hitach SH.
 618
 619 * Dis-assembler interface changed to allow sharing with gdb.
 620
 621 * There is new Elf code, but it is not yet ready for general use.
 622
 623 * There is the beginnings of a test suite.
 624
 625 Changes in binutils 2.1:
 626
 627 * There is now support for writing ECOFF files, so ld and the other utilities
 628   should work on Risc/Ultrix and Irix.  Please let us know how well this works.
 629
 630 * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
 631   version), if there are any object files in the archive.  So running ranlib is
 632   now redundant (unless the non-standard q command is used).  This is required
 633   for Posix.2 conformance.
 634
 635 * The archive-reading code now reads both BSD-style and SYSV-style archives
 636   independently of the selected target format.  This is to encourage people to
 637   switch to SYSV-format, which has a number of advantages.
 638
 639 * The strip and copy programs now have options to remove debug-symbols only
 640   and/or local symbols only.  They now also support long options.
