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