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