   3 * The separate debug info file options of readelf (--debug-dump=links
   4   and --debug-dump=follow) and objdump (--dwarf=links and
   5   --dwarf=follow-links) will now display and/or follow multiple links if
   6   more than one are present in a file.  (This usually happens when gcc's
   7   -gsplit-dwarf option is used).
   8
   9 Changes in 2.32:
  10
  11 * The addr2line, c++filt, nm and objdump tools now have a limit on the
  12   maximum amount of recursion that is allowed whilst demangling strings.
  13   The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
  14   constant declared in the include/demangle.h header file.  At the time
  15   of writing this constant has the value of 2048.
  16
  17   The --no-recurse-limit option can be used to remove the limit, restoring
  18   the behaviour of earlier versions of these tools.  This may be needed in
  19   order to dmangle truly complicated names, but it also leaves the tools
  20   vulnerable to stack exhaustion from maliciously constructed mangled names.
  21
  22 * Objdump's --disassemble option can now take a parameter, specifying the
  23   starting symbol for disassembly.  Disassembly will continue from this
  24   symbol up to the next symbol or the end of the function.
  25
  26 * The MIPS port now supports the Loongson 2K1000 processor which implements
  27   the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE,
  28   Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for
  29   Loongson 2K1000 processor.
  30
  31 * The MIPS port now supports the Loongson 3A2000/3A3000 processor which
  32   implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE,
  33   Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e
  34   option for Loongson 3A2000/3A3000 processor.
  35
  36 * The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a,
  37   which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE
  38   and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson
  39   3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
  40   compatibility.
  41
  42 * The size tool now has a new output format '--format=GNU' or '-G'.  The
  43   results are displayed in a similar manor to the default berkeley layout,
  44   except read-only data is counted in the data column, not the text column.
  45   Additionally the total is only included once.
  46
  47 Changes in 2.31:
  48
  49 * Add support for disassembling netronome Flow Processor (NFP) firmware files.
  50
  51 * The AArch64 port now supports showing disassembly notes which are emitted
  52   when inconsistencies are found with the instruction that may result in the
  53   instruction being invalid.  These can be turned on with the option -M notes
  54   to objdump.
  55
  56 * The AArch64 port now emits warnings when a combination of an instruction and
  57   a named register could be invalid.
  58
  59 * Added O modifier to ar to display member offsets inside an archive
  60
  61 Changes in 2.30:
  62
  63 * Add --debug-dump=links option to readelf and --dwarf=links option to objdump
  64   which displays the contents of any .gnu_debuglink or .gnu_debugaltlink
  65   sections.
  66
  67   Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links
  68   option to objdump which causes indirect links into separate debug info files
  69   to be followed when dumping other DWARF sections.
  70
  71 Changes in 2.29:
  72
  73 * The MIPS port now supports microMIPS eXtended Physical Addressing (XPA)
  74   instructions for assembly and disassembly.
  75
  76 * The MIPS port now supports the microMIPS Release 5 ISA for assembly and
  77   disassembly.
  78
  79 * The MIPS port now supports the Imagination interAptiv MR2 processor,
  80   which implements the MIPS32r3 ISA, the MIPS16e2 ASE as well as a couple
  81   of implementation-specific regular MIPS and MIPS16e2 ASE instructions.
  82
  83 * The SPARC port now supports the SPARC M8 processor, which implements the
  84   Oracle SPARC Architecture 2017.
  85
  86 * The MIPS port now supports the MIPS16e2 ASE for assembly and disassembly.
  87
  88 * Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
  89
  90 * Add support for the wasm32 ELF conversion of the WebAssembly file format.
  91
  92 * Add --inlines option to objdump, which extends the --line-numbers option
  93   so that inlined functions will display their nesting information.
  94
  95 * Add --merge-notes options to objcopy to reduce the size of notes in
  96   a binary file by merging and deleting redundant notes.
  97
  98 * Add support for locating separate debug info files using the build-id
  99   method, where the separate file has a name based upon the build-id of
 100   the original file.
 101
 102 Changes in 2.28:
 103
 104 * This version of binutils fixes a problem with PowerPC VLE 16A and 16D
 105   relocations which were functionally swapped, for example,
 106   R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
 107   performed like R_PPC_VLE_HA16A.  This could have been fixed by
 108   renumbering relocations, which would keep object files created by an
 109   older version of gas compatible with a newer ld.  However, that would
 110   require an ABI update, affecting other assemblers and linkers that
 111   create and process the relocations correctly.  It is recommended that
 112   all VLE object files be recompiled, but ld can modify the relocations
 113   if --vle-reloc-fixup is passed to ld.  If the new ld command-line
 114   option is not used, ld will ld warn on finding relocations inconsistent
 115   with the instructions being relocated.
 116
 117 * The nm program has a new command-line option (--with-version-strings)
 118   which will display a symbol's version information, if any, after the
 119   symbol's name.
 120
 121 * The ARC port of objdump now accepts a -M option to specify the extra
 122   instruction class(es) that should be disassembled.
 123
 124 * The --remove-section option for objcopy and strip now accepts section
 125   patterns starting with an exclamation point to indicate a non-matching
 126   section.  A non-matching section is removed from the set of sections
 127   matched by an earlier --remove-section pattern.
 128
 129 * The --only-section option for objcopy now accepts section patterns
 130   starting with an exclamation point to indicate a non-matching section.
 131   A non-matching section is removed from the set of sections matched by
 132   an earlier --only-section pattern.
 133
 134 * New --remove-relocations=SECTIONPATTERN option for objcopy and strip.
 135   This option can be used to remove sections containing relocations.
 136   The SECTIONPATTERN is the section to which the relocations apply, not
 137   the relocation section itself.
 138
 139 Changes in 2.27:
 140
 141 * Add a configure option, --enable-64-bit-archive, to force use of a
 142   64-bit format when creating an archive symbol index.
 143
 144 * Add --elf-stt-common= option to objcopy for ELF targets to control
 145   whether to convert common symbols to the STT_COMMON type.
 146
 147 Changes in 2.26:
 148
 149 * Add option to objcopy to insert new symbols into a file:
 150   --add-symbol <name>=[<section>:]<value>[,<flags>]
 151
 152 * Add support for the ARC EM/HS, and ARC600/700 architectures.
 153
 154 * Extend objcopy --compress-debug-sections option to support
 155   --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
 156   targets.
 157
 158 * Add --update-section option to objcopy.
 159
 160 * Add --output-separator option to strings.
 161
 162 Changes in 2.25:
 163
 164 * Add --data option to strings to only print strings in loadable, initialized
 165   data sections.  Change the default behaviour to be --all, but add a new
 166   configure time option of --disable-default-strings-all to restore the old
 167   default behaviour.
 168
 169 * Add --include-all-whitespace to strings.
 170
 171 * Add --dump-section option to objcopy.
 172
 173 * Add support for the Andes NDS32.
 174
 175 Changes in 2.24:
 176
 177 * Objcopy now supports wildcard characters in command-line options that take
 178   section names.
 179
 180 * Add support for Altera Nios II.
 181
 182 Changes in 2.23:
 183
 184 * Add support for the VLE extension to the PowerPC architecture.
 185
 186 * Add support for x64 Windows target of the delayed-load-library.
 187
 188 * Add support for the Renesas RL78 architecture.
 189
 190 Changes in 2.22:
 191
 192 * Add support for displaying the contents of .debug.macro sections.
 193
 194 * Add --preprocessor-arg option to windres to specify additional options
 195   passed to preprocessor.
 196
 197 * Add --dwarf-start and --dwarf-end to readelf and objdump.  These are used by
 198   the new Emacs mode, see dwarf-mode.el.
 199
 200 * Add support for the Tilera TILEPro and TILE-Gx architectures.
 201
 202 changes in 2.21:
 203
 204 * Add --interleave-width option to objcopy to allowing copying a range of
 205   bytes from the input to the output with the --interleave option.
 206
 207 * Add support for the TMS320C6000 (TI C6X) processor family.
 208
 209 * Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using
 210   the -u / --unwind option.
 211
 212 * Add --dyn-syms to readelf to dump dynamic symbol table.
 213
 214 * A new tool - elfedit - has been added to directly manipulate ELF format
 215   binaries.
 216
 217 * Add to dlltool .def file feature of aliasing PE internal symbol name by
 218   '== <ID>' option.
 219
 220 * Add a new command-line option -a / --addresses to addr2line to display the
 221   address before function name or source filename.
 222
 223 * Add a new command-line option -p / --pretty-print to addr2line to have
 224   a more human readable output.
 225
 226 * The hppa/som targets can now be compiled on any host.
 227
 228 Changes in 2.20:
 229
 230 * Add support for delay importing to dlltool.  Use the --output-delaylib <file>
 231   switch to create a delay-import library.  The resulting app will load the dll
 232   as soon as the first function is called.  It will link to __delayLoadHelper2()
 233   from the static delayimp library, which will import LoadLibraryA and
 234   GetProcAddress from kernel32.
 235
 236 * Add a new command-line option, --insn-width=WIDTH, to objdump to specify
 237   number of bytes to be displayed on a single line when disassembling
 238   instructions.
 239
 240 * Readelf can now display the relocated contents of a section as a sequence
 241   of bytes via the --relocated-dump=<name|number> command-line option.
 242
 243 * The gprof program has been given a new command-line option:
 244   --external-symbols-table=<filename> which reads in symbols from a specified
 245   file.
 246
 247 * The plugin target has been added to bfd. It can load the same shared objects
 248   used by gold and uses them to provide basic support for new file formats.
 249
 250 * The verilog memory hex dump file format is now supported as an output format
 251   for objcopy.
 252
 253 * Add --file-alignment, --heap, --image-base, --section-alignment,
 254   --stack and --subsystem command-line options to objcopy, which will
 255   set PE optional header.
 256
 257 * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w.
 258
 259 * --as-needed now links in a dynamic library if it satisfies undefined
 260   symbols in regular objects, or in other dynamic libraries.  In the
 261   latter case the library is not linked if it is found in a DT_NEEDED
 262   entry of one of the libraries already linked.
 263
 264 * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to
 265   add absolute paths for -S.
 266
 267 * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall-
 268   back to old import table generation with null element prefix.
 269
 270 * Added --identify-strict switch to cause --identify <implib> to
 271   report an error when the import library is associated with
 272   multiple DLLs.
 273
 274 * Added --identify <implib> option to dlltool, which determines the
 275   name of the DLL associated with the specified <implib>.
 276
 277 * Support for PowerPC booke64 instructions has been removed.  The assembler no
 278   longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts
 279   -Mbooke32 or -Mbooke64.  Instead, -mbooke and -Mbooke should be used.
 280
 281 Changes in 2.19:
 282
 283 * Added -wL switch to dump decoded contents of .debug_line.
 284
 285 * Added support for "thin" archives which contain pathnames pointing to
 286   object files rather than the files themselves and which contain a
 287   flattened symbol index for all objects, and archives, which have been
 288   added to the archive.
 289
 290 * Added -F switch to objdump to include file offsets in the disassembly.
 291
 292 * Added -c switch to readelf to allow string dumps of archive symbol index.
 293
 294 * Support for SSE5 has been added to the i386 port.
 295
 296 * Added -p switch to readelf to allow string dumps of sections.
 297
 298 Changes in 2.18:
 299
 300 * Resolved 37 coding problems in bfd including static array overruns, null
 301   pointer dereferences and use of a malloc buffer after it has been freed, as
 302   revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com).
 303
 304 * The binutils sources are now released under version 3 of the GNU General
 305   Public License.
 306
 307 * A new tool "windmc" has been added for some targets.  This is a message
 308   compiler which attempts to be compatible with the MS version.
 309
 310 * Add codepage support to the windres tool.  It now supports many new
 311   resource types (e.g. MANIFEST, TOOLBAR, etc).  The output generation
 312   for binary files is done now via bfd itself.  The endianess problems
 313   for different hosts are solved.  Dumps of .res files can now be
 314   re-compiled by windres without lossing resources or compilation errors.
 315   Some problems on dialog resource translations are corrected.
 316
 317 * Add --extract-symbol command-line option to objcopy, which will
 318   strip everything out of an ordinary object file or executable except
 319   for its symbol table.  Files containing just symbols can be useful
 320   to some OSes.
 321
 322 Changes in 2.17:
 323
 324 * Add "-x NAME" to readelf in addition to "-x NUMBER".
 325
 326 * Add -i and -t switches to cxxfilt.  -i disables the display of implementation
 327   specific extra demangling information (if any) and -t disables the demangling
 328   of types.
 329
 330 * Add support for the "@<file>" syntax to the command lines of all tools, so
 331   that extra switches can be read from <file>.
 332
 333 * Add "-W/--dwarf" to objdump to display the contents of the DWARF
 334   debug sections.
 335
 336 * Add "-t/--section-details" to readelf to display section details.
 337   "-N/--full-section-name" is deprecated.
 338
 339 * powerpc-linux ld now supports a variant form of PLT and GOT for the security
 340   conscious.  This form will automatically be chosen when ld detects that all
 341   code in regular object files was generated by gcc -msecure-plt.  The old PLT
 342   and GOT may be forced by a new ld option, --bss-plt.
 343
 344 * Add "-i/--inlines" to addr2line to print enclosing scope information
 345   for inlined function chains, back to first non-inlined function.
 346
 347 * Add "-N/--full-section-name" to readelf to display full section name.
 348
 349 * Add "-M entry:<addr>" switch to objdump to specify a function entry address
 350   when disassembling VAX binaries.
 351
 352 * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches
 353   to objcopy to convert local symbols into global symbols.
 354
 355 * gprof now allows input files to have histogram records for
 356   several memory ranges, provided those ranges are disjoint.
 357
 358 Changes in 2.16:
 359
 360 * Add "-g/--section-groups" to readelf to display section groups.
 361
 362 * objcopy recognizes two new options --strip-unneeded-symbol and
 363   --strip-unneeded-symbols, namely for use together with the wildcard
 364   matching the original --strip-symbol/--strip-symbols provided, but
 365   retaining any symbols matching but needed by relocations.
 366
 367 * readelf can now display address ranges from .debug_range sections.  This
 368   happens automatically when a DW_AT_range attribute is encountered.  The
 369   command-line switch --debug-dump=Ranges (or -wR) can also be used to display
 370   the contents of the .debug_range section.
 371
 372 * nm and objdump now have a switch "--special-syms" to enable the displaying of
 373   symbols which the target considers to be special.  By default these symbols
 374   are no longer displayed.  Currently the only special symbols are the Mapping
 375   symbols used by the ARM port to mark transitions between text and data and
 376   between ARM and THUMB code.
 377
 378 * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional
 379   import and export symbols with <preifx> prepended to them.
 380
 381 Changes in 2.15:
 382
 383 * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
 384   disassembler to print the "raw" mips instruction mnemonic instead of some
 385   pseudo instruction name.  I.E. print "daddu" or "or" instead of "move",
 386   "sll" instead of "nop", etc.
 387
 388 * objcopy and strip can now take wildcard patterns in symbol names specified on
 389   the command line provided that the --wildcard switch is used to enable them.
 390
 391 * readelf can now parse archives.
 392
 393 * objdump now accepts --debugging-tags to print the debug information in a
 394   format compatible with ctags tool.
 395
 396 * objcopy and strip now accept --only-keep-debug to create a file containing
 397   those sections that would be stripped out by --strip-debug.  The idea is that
 398   this can be used in conjunction with the --add-gnu-debuglink switch to create
 399   a two part program distribution - one a stripped executable and the other the
 400   debugging info.
 401
 402 * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink
 403   section into a (presumably stripped) executable.  This allows the debug
 404   information for the file to be held in a separate file.
 405
 406 * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
 407   single-character representation.  This can be checked by running nm
 408   with the -a switch.
 409
 410 Changes in 2.14:
 411
 412 * Added --info switch to objcopy and strip.
 413
 414 * Support for Vitesse IQ2000 added by Red Hat.
 415
 416 * Added 'S' encoding to strings to allow the display of 8-bit characters.
 417
 418 * Added --prefix-symbols=<text>, --prefix-sections=<text> and
 419   --prefix-alloc-sections=<text> to objcopy.
 420
 421 * readelf can handle the extensions to the DWARF2 spec used by the Unified
 422   Parallel C compiler.
 423
 424 * BFD no longer declares a "boolean" type, to avoid clashes with other
 425   headers that declare the same.  Users of BFD should replace boolean,
 426   false and true, with int, 0 and 1, or define their own boolean type.
 427
 428 * Support for IP2K added by Denis Chertykov.
 429
 430 Changes in 2.13:
 431
 432 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 433   and FR500 included.
 434
 435 Changes in version 2.12:
 436
 437 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 438
 439 * size: Add --totals to display summary of sizes (Berkeley format only).
 440
 441 * readelf: Add --wide option to not break section header or segment listing
 442   lines to fit into 80 columns.
 443
 444 * strings: Add --encoding to display wide character strings.  By Markus Kuhn.
 445
 446 * objcopy: Add --rename-section to change section names.
 447
 448 * readelf: Support added for DWARF 2.1 extensions.  Support added for
 449   displaying the contents of .debug.macinfo sections.
 450
 451 * New command-line switches added to objcopy to allow symbols to be kept as
 452   global symbols, and also to specify files containing lists of such symbols.
 453   by Honda Hiroki.
 454
 455 * Support for OpenRISC by Johan Rydberg.
 456
 457 * New command-line switch to objcopy --alt-machine-code which creates a binary
 458   with an alternate machine code if one is defined in the architecture
 459   description.  Only supported for ELF targets.  By Alexandre Oliva.
 460
 461 * New command-line switch to objcopy -B (or --binary-architecture) which sets
 462   the architecture of the output file to the given argument.  This option only
 463   makes sense, if the input target is binary.  Otherwise it is ignored.
 464   By Stefan Geuken.
 465
 466 * Support for PDP-11 by Lars Brinkhoff.
 467
 468 Changes in binutils 2.11:
 469
 470 * Add support for ARM v5t and v5te architectures and Intel's XScale ARM
 471   extenstions.
 472
 473 * Add --srec-len and --srec-forceS3 command-line switch to objcopy.
 474   By Luciano Gemme.
 475
 476 * Support for the MIPS32, by Anders Norlander.
 477
 478 * Support for the i860, by Jason Eckhardt.
 479
 480 * Support for CRIS (Axis Communications ETRAX series).
 481
 482 Changes in binutils 2.10:
 483
 484 * Support for 64-bit ELF on HPPA.
 485
 486 * New command-line switch to objdump --file-start-context which shows the
 487   entire file contents up to the source line first encountered for a given
 488   file.
 489
 490 * New command-line switch to objdump -M (or --disassembler-options) which takes
 491   a parameter which can then be interpreted on a per-target basis by the
 492   disassembler.  Used by ARM targets to select register name sets, ISA, APCS or
 493   raw verions.
 494
 495 * objdump support for -mi386:intel which causes disassembly to be displayed
 496   with intel syntax.
 497
 498 * New program: readelf.  This displays the contents of ELF format files,
 499   regardless of target machine.

 501 * objcopy now takes --change-section-lma, --change-section-vma, and
 502   --change-section-address options.  The old --adjust-section-vma option is
 503   equivalent to --change-section-address.  The other --adjust-* options are now
 504   renamed to --change-*, although --adjust-* continues to work.
 505
 506 * objcopy has a --redefine-sym option that lets you rename symbols.
 507
 508 * objcopy now takes a -j/--only-section option to copy only the specified
 509   sections.
 510
 511 * dlltool now supports the IMPORTS command.
 512
 513 * dlltool now takes --export-all-symbols, --no-export-all-symbols,
 514   --exclude-symbols, and --no-default-excludes options.
 515
 516 Changes in binutils 2.9:
 517
 518 * Added windres program, which can be used to manipulate resources in WIN32
 519   files as used on Windows 95 and Windows NT.
 520
 521 * The objcopy --gap-fill and --pad-to options operate on the LMA rather than
 522   the VMA of the sections.
 523
 524 * Added S modifier to ar to not build a symbol table.
 525
 526 Changes in binutils 2.8:
 527
 528 * The objdump disassembly format has been changed, and hopefully improved.  Use
 529   the new --prefix-addresses option to get the old format.  There are also new
 530   --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
 531   output.
 532
 533 * Formats may now be specified as configuration triplets.  For example,
 534   objdump -b i386-pc-linux.  The triplets are not passed through config.sub,
 535   so they must be in canonical form.
 536
 537 * Added new addr2line program.  This uses the debugging information to convert
 538   an address into a file name and line number within a program.
 539
 540 * Added --change-leading-char argument to objcopy.
 541
 542 * Added --weaken argument to objcopy.
 543
 544 * objdump --dynamic-reloc now works on ELF executables and shared libraries.
 545
 546 * Added --adjust-vma option to objdump.
 547
 548 * Added -C/--demangle option to objdump.
 549
 550 * Added -p/--preserve-dates option to strip and objcopy.
 551
 552 Changes in binutils 2.7:
 553
 554 * Added --enable-shared and --enable-commonbfdlib options to configure.
 555
 556 * Added --debugging argument to objdump and objcopy.
 557
 558 * Added --defined-only argument to nm.
 559
 560 * Added --remove-leading-char argument to objcopy.
 561
 562 * The objdump --line-numbers option is now meaningful with --reloc.
 563
 564 * Added --line-numbers option to nm.
 565
 566 * Added --endian/-EB/-EL option to objdump.
 567
 568 * Added support for Alpha OpenVMS/AXP.
 569
 570 Changes in binutils 2.6:
 571
 572 * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
 573
 574 * Added several arguments to objcopy to provide some control over how the new
 575   file is laid out in memory.  Also added binary output format to BFD to permit
 576   generating plain binary files.
 577
 578 * Added --start-address and --stop-address options to objdump.
 579
 580 * ar and ranlib now work on AIX.  The tools are now built by default on AIX.
 581
 582 Changes in binutils 2.5:
 583
 584 * Changed objdump -dr to dump the relocs interspersed with the assembly
 585   listing, for a more useful listing of relocatable files.
 586
 587 * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
 588   Added -D/--disassemble-all option to disassemble all sections.
 589
 590 * Added --size-sort option to nm.
 591
 592 * strip and objcopy should now be able to handle dynamically linked ELF
 593   executables.
 594
 595 Changes in binutils 2.4:
 596
 597 * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
 598   PowerPC (except ar and ranlib; by Ian Taylor).
 599
 600 * Support for Irix 5.
 601
 602 * Programs `strip' and `objcopy' will not attempt to write dynamically linked
 603   ELF output files, since BFD currently can't create them properly.
 604
 605 Changes in binutils 2.3:
 606
 607 * A new --stabs argument has been added to objdump to dump stabs sections in
 608   ELF and COFF files.
 609
 610 * A new program, nlmconv, has been added.  It can convert object files into
 611   Novell NetWare Loadable Modules.
 612
 613 * The strings program has been added.
 614
 615 Changes in binutils 2.2:
 616
 617 * The 'copy' program has been renamed to 'objcopy', for consistency with
 618   'objdump', and because 'copy' might more plausibly be used as a synonym for
 619   'cp'.
 620
 621 * The new stand-alone program c++filt is a filter that converts encoded
 622   (mangled) C++ assembly-level identifiers to user-level names.  (Note: This
 623   may get moved to the gcc distribution.)
 624
 625 * nm -o on an archive now prefixes each line with the archive name, matching
 626   the output from BSD nm.
 627
 628 * ar (and ld) can now read (but not write) BSD4.4-style archives.
 629
 630 * New support for H8500, Z8000, and the Hitach SH.
 631
 632 * Dis-assembler interface changed to allow sharing with gdb.
 633
 634 * There is new Elf code, but it is not yet ready for general use.
 635
 636 * There is the beginnings of a test suite.
 637
 638 Changes in binutils 2.1:
 639
 640 * There is now support for writing ECOFF files, so ld and the other utilities
 641   should work on Risc/Ultrix and Irix.  Please let us know how well this works.
 642
 643 * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
 644   version), if there are any object files in the archive.  So running ranlib is
 645   now redundant (unless the non-standard q command is used).  This is required
 646   for Posix.2 conformance.
 647
 648 * The archive-reading code now reads both BSD-style and SYSV-style archives
 649   independently of the selected target format.  This is to encourage people to
 650   switch to SYSV-format, which has a number of advantages.
 651
 652 * The strip and copy programs now have options to remove debug-symbols only
 653   and/or local symbols only.  They now also support long options.
