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