   2
   3 * Support for -z noreloc-overflow in the x86-64 ELF linker to disable
   4   relocation overflow check.
   5
   6 * Add -z common/-z nocommon options for ELF targets to control whether to
   7   convert common symbols to the STT_COMMON type during a relocatable link.
   8
   9 * Support for -z nodynamic-undefined-weak in the x86 ELF linker, which
  10   avoids dynamic relocations against undefined weak symbols in executable.
  11
  12 * The NOCROSSREFSTO command was added to the linker script language.
  13
  14 * Add --no-apply-dynamic-relocs to the AArch64 linker to do not apply link-time
  15   values for dynamic relocations.
  16
  17 Changes in 2.26:
  18
  19 * Add --fix-stm32l4xx-629360 to the ARM linker to enable a link-time
  20   workaround for a bug in the bus matrix / memory controller for some of
  21   the STM32 Cortex-M4 based products (STM32L4xx)
  22
  23 * Add a configure option --enable-compressed-debug-sections={all,ld} to
  24   decide whether DWARF debug sections should be compressed by default.
  25
  26 * Add support for the ARC EM/HS, and ARC600/700 architectures.
  27
  28 * Experimental support for linker garbage collection (--gc-sections)
  29   has been enabled for COFF and PE based targets.
  30
  31 * New command line option for ELF targets to compress DWARF debug
  32   sections, --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi].
  33
  34 * New command line option, --orphan-handling=[place|warn|error|discard], to
  35   adjust how orphan sections are handled.  The default is 'place' which gives
  36   the current behaviour, 'warn' and 'error' issue a warning or error
  37   respectively when orphan sections are found, and 'discard' will discard all
  38   orphan sections.
  39
  40 * Add support for LLVM plugin.
  41
  42 * Add --print-memory-usage option to report memory blocks usage.
  43
  44 * Add --require-defined option, it's like --undefined except the new symbol
  45   must be defined by the end of the link.
  46
  47 Changes in 2.25:
  48
  49 * PE binaries now once again contain real timestamps by default.  To disable
  50   the inclusion of a timestamp in a PE binary, use the --no-insert-timestamp
  51   command line option.
  52
  53 * Replace support for openrisc and or32 with support for or1k.
  54
  55 * Add support for the --build-id command line option to COFF based targets.
  56
  57 * x86/x86_64 pe-coff now supports the --build-id option.
  58
  59 * Add support for the Andes NDS32.
  60
  61 Changes in 2.24:
  62
  63 * Add LOG2CEIL() builtin function to the linker script language
  64
  65 * Add support for the Texas Instruments MSP430X processor.
  66
  67 * Add support for Altera Nios II.
  68
  69 * Add support for the V850E3V5 architecture.
  70
  71 * Add support for the Imagination Technologies Meta processor.
  72
  73 * --enable-new-dtags no longer generates old dtags in addition to new dtags.
  74
  75 * Remove linker support for MIPS ECOFF targets.
  76
  77 * Add ALIGN_WITH_INPUT to the linker script language to force the alignment of
  78   an output section to use the maximum alignment of all its input sections.
  79
  80 Changes in 2.23:
  81
  82 * Enable compressed debug section feature for x86/x86_64 pe-coff.
  83
  84 * Add support for the 64-bit ARM architecture: AArch64.
  85
  86 * Added SORT_NONE to the linker script language to disable section sorting.
  87
  88 * Add a linker-provided symbol when producing ELF output, '__ehdr_start'
  89   to point to the ELF file header (and nearby program headers) in the
  90   program's memory image.
  91
  92 * Add support for S12X processor.
  93
  94 * Add support for the VLE extension to the PowerPC architecture.
  95
  96 * Add support for the Freescale XGATE architecture.
  97
  98 * Add option -f FILE on AIX (for response file).
  99
 100 * Add support for the Renesas RL78 architecture.
 101
 102 * Add support for the Adapteva EPIPHANY architecture.
 103
 104 Changes in 2.22:
 105
 106 * --copy-dt-needed-entries is no longer enabled by default.  Instead
 107   --no-copy-dt-needed-entries is the default.
 108
 109 * INPUT_SECTION_FLAGS has been added to the linker script language
 110   to allow selection of input sections by section header section flags.
 111
 112 * Add support for the Tilera TILEPro and TILE-Gx architectures.
 113
 114 * Added SORT_BY_INIT_PRIORITY to the linker script language to permit
 115   sorting sections by numerical value of the GCC init_priority attribute
 116   encoded in the section name.
 117
 118 Changes in 2.21:
 119
 120 * Linker script expression evaluation is somewhat more sane.  This may
 121   break scripts that depend on quirks of the old expression evaluation.
 122
 123 * Turn off underscoring for x86_64 PE+-COFF targets.  For old behavior the
 124   option --enable-leading-mingw64-underscores can be used on configure of
 125   bfd.
 126
 127 * Add support for the TMS320C6000 (TI C6X) processor family.
 128
 129 * --add-needed renamed to --copy-dt-needed-entries in order to avoid confusion
 130   with --as-needed option.
 131
 132 * Extend .def file syntax by '== <ID>' for imports and exports. This allows
 133   to alias the import/export table name written in PE image.
 134
 135 * Add --exclude-all-symbols option to PE based linkers.  This prevents all
 136   symbols from automatically being exported.
 137
 138 * Add support for the Renesas RX processor.
 139
 140 * Add support for alpha-vms target.
 141
 142 Changes in 2.20:
 143
 144 * GNU/Linux targets now support the STB_GNU_UNIQUE symbol binding.  This is a
 145   GNU extension to the standard set of ELF symbol bindings.  The binding will
 146   be passed on to the dynamic linker which will make sure that in the entire
 147   process there is just one symbol with the given name and type in use.
 148
 149 * PE targets now support a GNU extension to allow the alignment of common
 150   common symbols to be specified.  This support uses custom options in
 151   the .drectve section, which will be disregarded by the native tools.
 152
 153 * PE targets now add primitive support for ELF version scripts; symbols
 154   are not versioned, but the local and global symbol visibility directives
 155   are respected when filtering symbols in auto-export mode.
 156
 157 * New option --no-export-dynamic to undo the effect of the -E and
 158   --export-dynamic options.
 159
 160 * ELF: --warn-alternate-em option to warn if an object has alternate
 161   ELF machine code.
 162
 163 * New script function REGION_ALIAS to add alias names to memory regions.
 164
 165 * PE targets no longer make use of the long section names PE extension to
 166   the COFF format when generating executable images, by default.  The old
 167   (slightly non-conformant) behaviour can still be invoked by using the
 168   new '--enable-long-section-names' command-line option.  It is also enabled
 169   automatically in the presence of un-stripped debug information, as GDB
 170   needs to be able to find the debug info sections by their full names.
 171
 172 * For GNU/Linux systems the linker will now avoid processing any relocations
 173   made against symbols of the STT_GNU_IFUNC type and instead emit them into
 174   the resulting binary for processing by the loader.
 175
 176 * --as-needed now links in a dynamic library if it satisfies undefined
 177   symbols in regular objects, or in other dynamic libraries.  In the
 178   latter case the library is not linked if it is found in a DT_NEEDED
 179   entry of one of the libraries already linked.
 180
 181 * Add a new command line option, -Ttext-segment ADDR, for ELF targets
 182   to set the address of the first byte of the text segment.
 183
 184 * Add support for Sunplus score architecture.
 185
 186 * Add new option --use-nul-prefixed-import-tables to ld for PE targets to
 187   allow fallback to old import table generation with null element prefix.
 188
 189 * Windows PE systems now support a new --exclude-modules-for-implib option,
 190   allowing users to partition object files and archive members between a DLL
 191   and its associated import library as they are generated during linking.
 192
 193 * Add support for Lattice Mico32 (lm32) architecture.
 194
 195 * Add CR16 ELF --embedded-relocs (used to embedded relocations into binaries
 196   for Embedded-PIC code) option.
 197
 198 * Add to the PE/PE+ targets the support of two different kinds of
 199   pseudo-relocations.  They can be selected by the switches
 200   --enable-runtime-pseudo-reloc-v1 and --enable-runtime-pseudo-reloc-v2.
 201   For the switch --enable-runtime-pseudo-reloc it uses for 32-bit
 202   runtime pseudo relocation version one, for 64-bit the version two.
 203
 204 Changes in 2.19:
 205
 206 * Linker scripts support a new INSERT command that makes it easier to
 207   augment the default script.
 208
 209 * Linker script input section filespecs may now specify a file within an
 210   archive by writing "archive:file".
 211
 212 * The --sort-common switch now has an optional argument which specifies the
 213   direction of sorting.
 214
 215 * The M68K linker now supports multiple GOT generation schemes controlled via
 216   the --got=<type> command line option.
 217
 218 * The ARM EABI linker will now generate stubs for function calls to symbols
 219   that are too far away.  The placement of the stubs is controlled by a new
 220   linker command line option: --stub-group-size=N.
 221
 222 Changes in 2.18:
 223
 224 * Linker sources now released under version 3 of the GNU General Public
 225   License.
 226
 227 * ELF: New --build-id option to generate a unique per-binary identifier
 228   embedded in a note section.
 229
 230 * Added support for National Semicondutor CompactRISC (ie CR16) target.
 231
 232 * -l:foo now searches the library path for a filename called foo,
 233   without converting it to libfoo.a or libfoo.so.
 234
 235 * Add a new command line option '--default-script=FILE' or '-dT FILE'
 236   which specifies a replacement for the built in, default linker
 237   script.
 238
 239 * ELF: Add -Bsymbolic-functions, --dynamic-list-cpp-new, which puts C++
 240   operator new and delete on the dynamic list, and --dynamic-list-data,
 241   builtin list for --dynamic-list, which puts global data symbols on the
 242   dynamic list.
 243
 244 * Add support for x86_64 PE+ target.
 245
 246 * Add support for Score target.
 247
 248 * ELF: Add --dynamic-list option to specify a list of global symbols
 249   whose references shouldn't be bound to the definition within the
 250   shared library, or a list of symbols which should be added to the
 251   symbol table in the executable.
 252
 253 * The default output section LMA has changed for allocatable sections from
 254   being equal to VMA, to keeping the difference between LMA and VMA the same as
 255   the previous output section in the same region.  This is a more useful
 256   default when using overlays and other cases where you specify an LMA
 257   differing from the VMA for some sections.
 258
 259 * New switch: --print-gc-sections to list any sections removed by garabge
 260   collection.
 261
 262 * ARM: Added --vfp11-denorm-fix option to work around an erratum in current
 263   VFP11 coprocessors.
 264
 265 Changes in 2.17:
 266
 267 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 268
 269 * Modify the Linux linker search order to better match ld.so search order.
 270   Look for DT_NEEDED libraries in paths specified by ld.so.conf before
 271   searching the default directories, rather than vice versa.
 272   Use $prefix/etc/ld.so.conf if it exists, otherwise /etc/ld.so.conf.
 273
 274 * PE-COFF: Forward exports from DLL's can now be specified in .def files
 275   passed directly to ld.
 276
 277 * Support for the Z80 processor family has been added.
 278
 279 * Add support for the "@<file>" syntax to the command line, so that extra
 280   switches can be read from <file>.
 281
 282 Changes in 2.16:
 283
 284 * Support for the R_ARM_V4BX relocation as defined in the ARM AAELF
 285   specification has been added via the --fix-v4bx command-line option.
 286
 287 * New linker script construct AS_NEEDED(), which sets the --as-needed flag
 288   for input files listed inside of it.
 289
 290 * A new command-line option, --sysroot, can be used to override the
 291   default sysroot location.  It only applies to toolchains that were
 292   configured using --with-sysroot.
 293
 294 * New linker script functions: ORIGIN() and LENGTH() which return information
 295   about a specified memory region.
 296
 297 * Port to MAXQ processor contributed by HCL Tech.
 298
 299 * Added SEGMENT_START to the linker script language to permit the user to
 300   override the base address for a segment from the command-line.
 301
 302 * ELF: --warn-shared-textrel option to warn if adding a DT_TEXTREL to a shared
 303   object.
 304
 305 * Added SORT_BY_NAME and SORT_BY_ALIGNMENT to the linker script
 306   language to permit sorting sections by section name or section
 307   maximum alignment.
 308
 309 * Added a new linker command line switch, --sort-section name|alignment,
 310   to sort sections by section name or maximum alignment.
 311
 312 * ELF: --add-needed/--no-add-needed options to control if a DT_NEEDED tag
 313   should be added when a shared library comes from DT_NEEDED tags.
 314
 315 * Support for the crx-elf target added.
 316
 317 * Support for the sh-symbianelf target added.
 318
 319 * A new linker command line switch has been added which allows the hash table
 320   size to be set to a suitable prime value near to its argument.  This switch
 321   is --hash-size=<NUMBER>.  Also if the switch --reduce-memory-overheads is
 322   used, and --hash-size has not been used, then the default value will be set
 323   to 1021.
 324
 325 * Linker map files are now generated with an O(N) algorithm for finding symbols
 326   that are defined in each section.  This uses about 40% more memory for
 327   symbols than the old O(N^2) algorithm.  You can use the new
 328   --reduce-memory-overheads option to select the old algorithm; this option
 329   might also be used in the future to select similar tradeoffs.
 330
 331 Changes in 2.15:
 332
 333 * ELF: --as-needed/--no-as-needed options to control if a DT_NEEDED tag should
 334   be added only when a shared library is referenced.
 335
 336 * PE: --large-address-aware option to indicate executables support virtual
 337   addresses greater than 2 gigabytes.
 338
 339 * DWARF 2 support for i386pe added.
 340
 341 * The linker script operator DEFINED() will now yield 1 only for a symbol that
 342   is defined before the statement where DEFINED is used.
 343
 344 * The MIPS --embedded-relocs (used to embed relocations into binaries for
 345   Embedded-PIC code) is deprecated and will be removed in a future release.
 346
 347 * cr16c support added by NSC.
 348
 349 * m32r Linux (ELF) support added by Renesas.
 350
 351 * Improved linker's handling of unresolved symbols.  The switch
 352   --unresolved-symbols=<method> has been added to tell the linker when it
 353   should report them and the switch --warn-unresolved-symbols has been added to
 354   make reports be issued as warning messages rather than errors.
 355
 356 Changes in 2.14:
 357
 358 * Added support for Xtensa architecture.
 359
 360 * Added --with-sysroot configure switch to specify a target system root, for
 361   linking against a target filesystem image.
 362
 363 * Added --accept-unknown-linker-format to restore old linker behaviour (pre
 364   2.14) of silently accepting and linking in any files in an unknown binary
 365   file format.
 366
 367 * Added --no-omagic to undo the effects of the -N option.
 368
 369 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 370   DSP's contributed by Michael Hayes and Svein E. Seldal.
 371
 372 * Added --with-lib-path configure switch to specify default value for
 373   LIB_PATH.
 374
 375 * ARM port to QNX operating system added by Graeme Peterson.
 376
 377 * IP2K support added by Denis Chertykov.
 378
 379 Changes in 2.13:
 380
 381 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 382   and FR500 included.
 383
 384 Changes in version 2.13:
 385
 386 * DEC VAX ELF support, by Matt Thomas.
 387
 388 Changes in version 2.12:
 389
 390 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 391
 392 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 393
 394 * Support for -z nocopyreloc in the x86 ELF linker, which disables
 395   production of copy relocs.  Warning: using this option may result in
 396   non-sharable applications.
 397
 398 * Support for -z combreloc in the ELF linker, which puts dynamic
 399   relocations against the same symbol together, so that dynamic linker
 400   can use an one-entry symbol lookup cache.
 401
 402 * Support for ELF SHF_MERGE section merging, by Jakub Jelinek.
 403
 404 Changes in version 2.11:
 405
 406 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 407
 408 * Support added for eliminating duplicate DWARF2 debug information by
 409   having the compiler generate the information in sections called
 410   .gnu.linkonce.wi.XXXX where XXXX is a checksum for the contents.  The
 411   linker then merges these sections together into the normal .debug_info
 412   section.
 413
 414 * The native ELF linker now searches the directories in DT_RUNPATH or
 415   DT_RPATH of a shared library for shared libraries needed by it.
 416
 417 * TI C54x support, by Timothy Wall.
 418
 419 * Added command line switch --section-start to set the start address of any
 420   specified section.
 421
 422 * Added ability to emit full relocation information in linked executables,
 423   enabled by --emit-relocs.  Some post-linkage optimization tools need
 424   this information in order to be able to correctly identify and perform
 425   symbol relative addressing in the event of changes in section contents
 426   (instructions being added or deleted, extending data sections, etc.)
 427
 428 * Support for i860, by Jason Eckhardt (preliminary, alpha quality).
 429
 430 * Support for CRIS (Axis Communications ETRAX series).
 431
 432 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 433
 434 Changes in version 2.10:
 435
 436 * Added AT> to the linker script language to allow load-time allocation of
 437   sections into regions.
 438
 439 * Added garbage collection of unused sections, enabled by --gc-sections.
 440   It does require a bit of backend support; currently implemented are
 441   arm-elf, avr-elf, d10v-elf, fr30-elf, i386-elf, m32r-elf, m68k-elf,
 442   mcore-elf, mips-elf, mn10300-elf, ppc-elf, sh-elf, sparc-elf, and v850-elf.
 443   Others will ignore the option.
 444
 445 * Added SORT to the linker script language to permit sorting sections by file
 446   name or section name.
 447
 448 * Added EXTERN to the linker script language as an equivalent to the -u
 449   command-line option.
 450
 451 * Added ASSERT to the linker script language.
 452
 453 * Added EXCLUDE_FILE to the linker script language for further control over
 454   wildcard file names.
 455
 456 * Added -O option to optimize linker output (as of this writing, this only
 457   affects ELF shared library generation).
 458
 459 * The -e option now accepts a number as well as a symbol name.
 460
 461 * Added --no-undefined option to disallow undefined symbols when creating a
 462   shared library.
 463
 464 * The linker now issues a warning, not an error, for an undefined symbol when
 465   using -Bsymbolic; use the new --no-undefined option to get the old
 466   behaviour.
 467
 468 * Added --demangle and --no-demangle options.
 469
 470 Changes in version 2.9:
 471
 472 * Added SQUAD to the linker script language.
 473
 474 * New option --no-warn-mismatch.
 475
 476 * The MEMORY command now parses the attributes to determine where sections that
 477   are not placed in a specific memory region are placed.
 478
 479 Changes in version 2.8:
 480
 481 * Linker scripts may now contain shell wildcard characters for file and section
 482   names.
 483
 484 * The linker now supports symbol versions in ELF.
 485
 486 * The NOCROSSREFS command was added to the linker script language.
 487
 488 * The LOADADDR expression was added to the linker script language.
 489
 490 * MAX and MIN functions were added to the linker script language.
 491
 492 * The OVERLAY construct was added to the linker script language.
 493
 494 * New option --warn-section-align to warn when the address of an output section
 495   changes due to alignment of an input section.
 496
 497 * New options --filter/-F and --auxiliary/-f.
 498
 499 Changes in version 2.7:
 500
 501 * New option --cref to print out a cross reference table.
 502
 503 * New option --wrap SYMBOL.
 504
 505 * New option --no-whole-archive, to turn off the effect of --whole-archive.
 506
 507 * Input sections assigned to the output section /DISCARD/ in the linker script
 508   are not included in the output file.
 509
 510 * The SunOS and ELF linkers now merge stabs debugging information which uses
 511   the N_BINCL and N_EINCL stab types.  This reduces the amount of debugging
 512   information generated.
 513
 514 Changes in version 2.6:
 515
 516 * When an ELF section name is representable as a C identifier (this is not true
 517 of most ELF section names), the linker will automatically define symbols
 518 __start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the
 519 beginning and the end of the section.  This is used by glibc.
 520
 521   Addendum: Current versions of the linker (at least for version 2.18 onwards
 522 and possibly much earlier as well) place two restrictions on this feature:  The
 523 symbols are only implemented for orphaned sections, not for explicitly placed
 524 sections and they are PROVIDEd rather than being defined.
 525
 526 * When an ELF section named .gnu.warning is encountered in an input file, the
 527 contents of the section are displayed as an error message, and the section is
 528 not copied into the output file.  This is used by glibc.
 529
 530 * When an ELF section named .gnu.warning.SYMBOL is encountered in an input
 531 file, and the symbol SYMBOL is referenced by some object file, the contents of
 532 the section are displayed as an error message.  The section is not copied into
 533 the output file, unless doing a relocatable or shared link.  This is used by
 534 glibc.
 535
 536 * New options -split-by-reloc and -split-by-file.
 537
 538 * The linker now supports linking PIC compiled code on SPARC SunOS.  It can
 539 also create SPARC SunOS shared libraries, and, like the native SunOS linker,
 540 will do so whenever there is an undefined symbol in the link and neither the -e
 541 nor the -r option was used.
 542
 543 * The -rpath option may be used on SunOS to set the list of directories to be
 544 searched at run time.  This overrides the default of building the list from the
 545 -L options.
 546
 547 * The COFF linker now combines debugging information for structs, unions, and
 548 enums, so that even if the same type is defined in multiple input files it will
 549 only be defined once in the output file.  The --traditional-format switch will
 550 prevent this optimization.
 551
 552 Changes in version 2.5:
 553
 554 * The linker now supports linking against SunOS shared libraries.  It still can
 555 not link SunOS PIC (Position Independent Code) files, so it can not be used to
 556 generate shared libraries.
 557
 558 * The linker now supports linking against ELF shared libraries for the i386
 559 (UnixWare) and SPARC (Solaris).  It can also link ELF PIC files, and can be
 560 used to generate shared libraries.  Shared library generation is not well
 561 tested; please report any problems encountered.  The linker is now enabled for
 562 Solaris again.
 563
 564 * Eric Youngdale has contributed Linux support code, including linking against
 565 Linux a.out shared libraries.  The linker produces Linux QMAGIC binaries.
 566
 567 * The ELF backend has been converted to the new linker code.  To use the new
 568 ELF linker, each particular target requires a relocation function.  So far,
 569 this function has been written for i386 (UnixWare), SPARC (Solaris) MIPS (Irix
 570 5), and HPPA ELF targets.
 571
 572 * The -( (--start-group) and -) (--end-group) options have been added to
 573 support searching a group of archives as though they were a single archive.
 574 This can also be used in a linker script, as GROUP ( files ).
 575
 576 * When a file is named on the command line, and the linker does not recognize
 577 it as an object file, the linker will now treat the file as a linker script
 578 file.  A linker script named in this way augments, but does not replace, the
 579 default linker script.
 580
 581 * The -warn-once option was added.  It causes the linker to only warn once per
 582 undefined symbol, rather than once per reference.
 583
 584 * The COFF backend has been converted to the new linker code.  As with ELF, to
 585 use the new linker, each particular target requires a relocation function.  So
 586 far, this function has been written for the i386, m68k, a29k and SH targets.
 587
 588 * The -V flag was made a synonym for -v, for SVR4 compatibility.  The old -V
 589 behaviour is available via --verbose.
 590
 591 Changes in version 2.4:
 592
 593 * New linker code, by Steve Chamberlain and Ian Taylor.  For a.out and ecoff
 594   formats (so far), this should result in considerable savings in time
 595   and memory used while linking; slightly poorer performance than
 596   before for formats not converted yet.
 597
 598 * Command-line parsing is no longer done with flex.  This means
 599   oddball characters in filenames won't get treated as argument
 600   separators.
 601
 602 * HP-PA ELF support, by Jeff Law.  (No SOM support yet.)
 603
 604 * Mach i386 support, by David Mackenzie.
 605
 606 * Irix 4 shared libraries are now supported (Irix 5 uses ELF, and ELF shared
 607   libraries are not yet supported).
 608
 609 * COFF shared libraries (as on SCO) should work as well.
 610
 611 * The linker is disabled for Solaris.  (Actually, it was in 2.3 also, I just
 612   forgot to note it.)  Some of their C library routines don't work when
 613   statically linked, and the GNU linker doesn't support dynamic linking yet.
 614
 615 Changes in version 2.3:
 616
 617 * Weak symbols are now supported.
 618
 619 * ELF support has been added.  The linker has been bootstrapped on
 620   UnixWare and Solaris.
 621
 622 * Alpha OSF/1 support has been added (non dynamic linking only).
 623
 624 Changes in version 2.2:
 625
 626 * The `bfd' library has been updated to reduce a.out-format string
 627   table size.  The effect of this is that files linked from many input
 628   files with duplicate symbols (`-g' debugging records, or identical
 629   static symbols) should be much smaller.
 630
 631 Changes in version 2.1:
 632
 633 * The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented.
 634
 635 * There is now support for writing ECOFF files, so ld and the
 636   other utilities should work on Risc/Ultrix and Irix.
