   2 * Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
   3
   4 * Add --no-pad-sections to stop the assembler from padding the end of output
   5   sections up to their alignment boundary.
   6
   7 * Support for the ARMv8-M architecture has been added to the ARM port.  Support
   8   for the ARMv8-M Security and DSP Extensions has also been added to the ARM
   9   port.
  10
  11 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  12   .extCoreRegister pseudo-ops that allow an user to define custom
  13   instructions, conditional codes, auxiliary and core registers.
  14
  15 * Add a configure option --enable-elf-stt-common to decide whether ELF
  16   assembler should generate common symbols with the STT_COMMON type by
  17   default.  Default to no.
  18
  19 * New command line option --elf-stt-common= for ELF targets to control
  20   whether to generate common symbols with the STT_COMMON type.
  21
  22 * Add ability to set section flags and types via numeric values for ELF
  23   based targets.
  24
  25 * Add a configure option --enable-x86-relax-relocations to decide whether
  26   x86 assembler should generate relax relocations by default.  Default to
  27   yes, except for x86 Solaris targets older than Solaris 12.
  28
  29 * New command line option -mrelax-relocations= for x86 target to control
  30   whether to generate relax relocations.
  31
  32 * New command line option -mfence-as-lock-add=yes for x86 target to encode

  39
  40 Changes in 2.26:
  41
  42 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  43   decide whether DWARF debug sections should be compressed by default.

  49   them to contain characters that are not part of valid symbol names in high
  50   level languages.
  51
  52 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  53   previous spelling, -march=armv6zk, is still accepted.

  85   generation of DWARF .debug_line sections.
  86
  87 * Add support for Altera Nios II.
  88
  89 * Add support for the Imagination Technologies Meta processor.

 121
 122 * Add support for the TMS320C6000 (TI C6X) processor family.
 123
 124 * GAS now understands an extended syntax in the .section directive flags
 125   for COFF targets that allows the section's alignment to be specified.  This
 126   feature has also been backported to the 2.20 release series, starting with
 127   2.20.1.
 128
 129 * Add support for the Renesas RX processor.
 130
 131 * New command line option, --compress-debug-sections, which requests
 132   compression of DWARF debug information sections in the relocatable output
 133   file.  Compressed debug sections are supported by readelf, objdump, and
 134   gold, but not currently by Gnu ld.
 135
 136 Changes in 2.20:
 137
 138 * Added support for v850e2 and v850e2v3.
 139
 140 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 141   pseudo op.  It marks the symbol as being globally unique in the entire
 142   process.
 143
 144 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 145   in binary rather than text.
 146
 147 * Add support for common symbol alignment to PE formats.
 148
 149 * Add support for the new discriminator column in the DWARF line table,
 150   with a discriminator operand for the .loc directive.
 151
 152 * Add support for Sunplus score architecture.
 153
 154 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 155   indicate that if the symbol is the target of a relocation, its value should
 156   not be use.  Instead the function should be invoked and its result used as
 157   the value.
 158
 159 * Add support for Lattice Mico32 (lm32) architecture.
 160
 161 * Add support for Xilinx MicroBlaze architecture.
 162
 163 Changes in 2.19:
 164
 165 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 166   tables without runtime relocation.
 167
 168 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 169   adds compatibility with H'00 style hex constants.
 170
 171 * New command line option, -msse-check=[none|error|warning], for x86
 172   targets.
 173
 174 * New sub-option added to the assembler's -a command line switch to
 175   generate a listing output.  The 'g' sub-option will insert into the listing
 176   various information about the assembly, such as assembler version, the
 177   command line options used, and a time stamp.
 178
 179 * New command line option -msse2avx for x86 target to encode SSE
 180   instructions with VEX prefix.
 181
 182 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 183
 184 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 185   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 186   -mnaked-reg and -mold-gcc, for x86 targets.
 187
 188 * Support for generating wide character strings has been added via the new
 189   pseudo ops: .string16, .string32 and .string64.
 190
 191 * Support for SSE5 has been added to the i386 port.
 192
 193 Changes in 2.18:
 194
 195 * The GAS sources are now released under the GPLv3.
 196
 197 * Support for the National Semiconductor CR16 target has been added.
 198
 199 * Added gas .reloc pseudo.  This is a low-level interface for creating
 200   relocations.
 201
 202 * Add support for x86_64 PE+ target.
 203
 204 * Add support for Score target.
 205
 206 Changes in 2.17:
 207
 208 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 209
 210 * Support for ms2 architecture has been added.
 211
 212 * Support for the Z80 processor family has been added.
 213
 214 * Add support for the "@<file>" syntax to the command line, so that extra
 215   switches can be read from <file>.
 216
 217 * The SH target supports a new command line switch --enable-reg-prefix which,
 218   if enabled, will allow register names to be optionally prefixed with a $
 219   character.  This allows register names to be distinguished from label names.
 220
 221 * Macros with a variable number of arguments are now supported. See the
 222   documentation for how this works.
 223
 224 * Added --reduce-memory-overheads switch to reduce the size of the hash
 225   tables used, at the expense of longer assembly times, and
 226   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 227
 228 * Macro names and macro parameter names can now be any identifier that would
 229   also be legal as a symbol elsewhere. For macro parameter names, this is
 230   known to cause problems in certain sources when the respective target uses
 231   characters inconsistently, and thus macro parameter references may no longer
 232   be recognized as such (see the documentation for details).
 233
 234 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 235   for the VAX target in order to be more compatible with the VAX MACRO
 236   assembler.
 237
 238 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 239
 240 Changes in 2.16:
 241
 242 * Redefinition of macros now results in an error.
 243
 244 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 245
 246 * New command line option -munwind-check=[warning|error] for IA64
 247   targets.
 248
 249 * The IA64 port now uses automatic dependency violation removal as its default
 250   mode.
 251
 252 * Port to MAXQ processor contributed by HCL Tech.
 253
 254 * Added support for generating unwind tables for ARM ELF targets.
 255
 256 * Add a -g command line option to generate debug information in the target's
 257   preferred debug format.
 258
 259 * Support for the crx-elf target added.
 260
 261 * Support for the sh-symbianelf target added.
 262
 263 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 264   on pe[i]-i386; required for this target's DWARF 2 support.
 265
 266 * Support for Motorola MCF521x/5249/547x/548x added.
 267
 268 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 269   instrucitons.
 270
 271 * New command line option -mno-shared for MIPS ELF targets.
 272
 273 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 274   added to enter (and leave) alternate macro syntax mode.
 275
 276 Changes in 2.15:
 277
 278 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 279   deprecated and will be removed in a future release.
 280
 281 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 282
 283 * Added support for ARM V6.
 284
 285 * Added support for sh4a and variants.
 286
 287 * Support for Renesas M32R2 added.
 288
 289 * Limited support for Mapping Symbols as specified in the ARM ELF
 290   specification has been added to the arm assembler.
 291
 292 * On ARM architectures, added a new gas directive ".unreq" that undoes
 293   definitions created by ".req".
 294
 295 * Support for Motorola ColdFire MCF528x added.
 296
 297 * Added --gstabs+ switch to enable the generation of STABS debug format
 298   information with GNU extensions.
 299
 300 * Added support for MIPS64 Release 2.
 301
 302 * Added support for v850e1.
 303
 304 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 305   multiple nop instructions used for alignment within code sections
 306   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 307   switch disables the optimization.
 308
 309 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 310   existing -non_shared option.
 311
 312 Changes in 2.14:
 313
 314 * Added support for MIPS32 Release 2.
 315
 316 * Added support for Xtensa architecture.
 317
 318 * Support for Intel's iWMMXt processor (an ARM variant) added.
 319
 320 * An assembler test generator has been contributed and an example file that
 321   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 322
 323 * Support for SH2E added.
 324
 325 * GASP has now been removed.
 326
 327 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 328   DSP's contributed by Michael Hayes and Svein E. Seldal.
 329
 330 * Support for the Ubicom IP2xxx microcontroller added.
 331
 332 Changes in 2.13:
 333
 334 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 335   and FR500 included.
 336
 337 * Support for DLX processor added.
 338
 339 * GASP has now been deprecated and will be removed in a future release.  Use
 340   the macro facilities in GAS instead.
 341
 342 * GASP now correctly parses floating point numbers. Unless the base is
 343   explicitly specified, they are interpreted as decimal numbers regardless of
 344   the currently specified base.
 345
 346 Changes in 2.12:
 347
 348 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 349
 350 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 351
 352 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 353   specifying the target instruction set.  The old method of specifying the
 354   target processor has been deprecated, but is still accepted for
 355   compatibility.
 356
 357 * Support for the VFP floating-point instruction set has been added to
 358   the ARM assembler.
 359
 360 * New psuedo op: .incbin to include a set of binary data at a given point
 361   in the assembly.  Contributed by Anders Norlander.
 362
 363 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 364   but still works for compatability.
 365
 366 * The MIPS assembler no longer issues a warning by default when it
 367   generates a nop instruction from a macro. The new command line option
 368   -n will turn on the warning.
 369
 370 Changes in 2.11:
 371
 372 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 373
 374 * x86 gas now supports the full Pentium4 instruction set.
 375
 376 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 377
 378 * Support for Motorola 68HC11 and 68HC12.
 379
 380 * Support for Texas Instruments TMS320C54x (tic54x).
 381
 382 * Support for IA-64.
 383
 384 * Support for i860, by Jason Eckhardt.
 385
 386 * Support for CRIS (Axis Communications ETRAX series).
 387
 388 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 389
 390 * x86 gas -q command line option quietens warnings about register size changes
 391   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 392   translating various deprecated floating point instructions.
 393
 394 Changes in 2.10:
 395
 396 * Support for the ARM msr instruction was changed to only allow an immediate
 397   operand when altering the flags field.
 398
 399 * Support for ATMEL AVR.
 400
 401 * Support for IBM 370 ELF.  Somewhat experimental.
 402
 403 * Support for numbers with suffixes.
 404
 405 * Added support for breaking to the end of repeat loops.
 406
 407 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 408
 409 * New .elseif pseudo-op added.
 410
 411 * New --fatal-warnings option.
 412
 413 * picoJava architecture support added.
 414
 415 * Motorola MCore 210 processor support added.
 416
 417 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 418   assembly programs with intel syntax.
 419
 420 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 421
 422 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 423
 424 * Full 16-bit mode support for i386.
 425
 426 * Greatly improved instruction operand checking for i386.  This change will
 427   produce errors or warnings on incorrect assembly code that previous versions
 428   of gas accepted.  If you get unexpected messages from code that worked with
 429   older versions of gas, please double check the code before reporting a bug.
 430
 431 * Weak symbol support added for COFF targets.
 432
 433 * Mitsubishi D30V support added.
 434
 435 * Texas Instruments c80 (tms320c80) support added.
 436
 437 * i960 ELF support added.
 438
 439 * ARM ELF support added.
 440
 441 Changes in 2.9:
 442
 443 * Texas Instruments c30 (tms320c30) support added.
 444
 445 * The assembler now optimizes the exception frame information generated by egcs
 446   and gcc 2.8.  The new --traditional-format option disables this optimization.
 447
 448 * Added --gstabs option to generate stabs debugging information.
 449
 450 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 451   listing.
 452
 453 * Added -MD option to print dependencies.
 454
 455 Changes in 2.8:
 456
 457 * BeOS support added.
 458
 459 * MIPS16 support added.
 460
 461 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 462
 463 * Alpha/VMS support added.
 464
 465 * m68k options --base-size-default-16, --base-size-default-32,
 466   --disp-size-default-16, and --disp-size-default-32 added.
 467
 468 * The alignment directives now take an optional third argument, which is the
 469   maximum number of bytes to skip.  If doing the alignment would require
 470   skipping more than the given number of bytes, the alignment is not done at
 471   all.
 472
 473 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 474
 475 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 476   conditionals in listings.
 477
 478 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 479   the symbol is already defined.
 480
 481 Changes in 2.7:
 482
 483 * The PowerPC assembler now allows the use of symbolic register names (r0,
 484   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 485   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 486   added.
 487
 488 * Alpha Linux (ELF) support added.
 489
 490 * PowerPC ELF support added.
 491
 492 * m68k Linux (ELF) support added.
 493
 494 * i960 Hx/Jx support added.
 495
 496 * i386/PowerPC gnu-win32 support added.
 497
 498 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 499   default is to build COFF-only support.  To get a set of tools that generate
 500   ELF (they'll understand both COFF and ELF), you must configure with
 501   target=i386-unknown-sco3.2v5elf.
 502
 503 * m88k-motorola-sysv3* support added.
 504
 505 Changes in 2.6:
 506
 507 * Gas now directly supports macros, without requiring GASP.
 508
 509 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 510   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 511   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 512
 513 * Added --defsym SYM=VALUE option.
 514
 515 * Added -mips4 support to MIPS assembler.
 516
 517 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 518
 519 Changes in 2.4:
 520
 521 * Converted this directory to use an autoconf-generated configure script.
 522
 523 * ARM support, from Richard Earnshaw.
 524
 525 * Updated VMS support, from Pat Rankin, including considerably improved
 526   debugging support.
 527
 528 * Support for the control registers in the 68060.
 529
 530 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 531   provide for possible future gcc changes, for targets where gas provides some
 532   features not available in the native assembler.  If the native assembler is
 533   used, it should become obvious pretty quickly what the problem is.
 534
 535 * Usage message is available with "--help".
 536
 537 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 538   also, but didn't get into the NEWS file.)
 539
 540 * Weak symbol support for a.out.
 541
 542 * A bug in the listing code which could cause an infinite loop has been fixed.
 543   Bugs in listings when generating a COFF object file have also been fixed.
 544
 545 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 546   Paul Kranenburg.
 547
 548 * Improved Alpha support.  Immediate constants can have a much larger range
 549   now. Support for the 21164 has been contributed by Digital.
 550
 551 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 552
 553 Changes in 2.3:
 554
 555 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 556
 557 * RS/6000 and PowerPC support by Ian Taylor.
 558
 559 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 560   based on mail received from various people.  The `-h#' option should work
 561   again too.
 562
 563 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 564   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 565   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 566   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 567   in the "dist" directory.
 568
 569 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 570   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 571   currently required for BSD 4.3 builds.)
 572
 573 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 574   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 575   the alpha-a.out support is pretty badly mangled, and much of it removed;
 576   making it work will require rewriting it as BFD support for the format anyways.
 577
 578 * Irix 5 support.
 579
 580 * The test suites have been fixed up a bit, so that they should work with a
 581   couple different versions of expect and dejagnu.
 582
 583 * Symbols' values are now handled internally as expressions, permitting more
 584   flexibility in evaluating them in some cases.  Some details of relocation
 585   handling have also changed, and simple constant pool management has been
 586   added, to make the Alpha port easier.
 587
 588 * New option "--statistics" for printing out program run times.  This is
 589   intended to be used with the gcc "-Q" option, which prints out times spent in
 590   various phases of compilation.  (You should be able to get all of them
 591   printed out with "gcc -Q -Wa,--statistics", I think.)
 592
 593 Changes in 2.2:
 594
 595 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 596
 597 * Configurations that are still in development (and therefore are convenient to
 598   have listed in configure.in) still get rejected without a minor change to
 599   gas/Makefile.in, so people not doing development work shouldn't get the
 600   impression that support for such configurations is actually believed to be
 601   reliable.
 602
 603 * The program name (usually "as") is printed when a fatal error message is
 604   displayed.  This should prevent some confusion about the source of occasional
 605   messages about "internal errors".
 606
 607 * ELF support is falling into place.  Support for the 386 should be working.
 608   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 609
 610 * Symbol values are maintained as expressions instead of being immediately
 611   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 612   more complex calculations involving symbols whose values are not alreadey
 613   known.
 614
 615 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 616   If any stabs directives are seen in the source, GAS will create two new
 617   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 618   section is nearly identical to the a.out symbol format, and .stabstr is
 619   its string table.  For this to be useful, you must have configured GCC
 620   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 621   that can use the stab sections (4.11 or later).
 622
 623 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 624   support is in progress.
 625
 626 Changes in 2.1:
 627
 628 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 629   incorporated, but not well tested yet.
 630
 631 * Altered the opcode table split for m68k; it should require less VM to compile
 632   with gcc now.
 633
 634 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 635   suggested by Ronald Cole.
 636
 637 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 638   includes improved ELF support, which I've started adapting for SPARC Solaris
 639   2.x.  Integration isn't completely, so it probably won't work.
 640
 641 * HP9000/300 support, donated by HP, has been merged in.
 642
 643 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 644
 645 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 646
 647 * Test suite framework is starting to become reasonable.
 648
 649 Changes in 2.0:
 650
 651 * Mostly bug fixes.
 652
 653 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 654
 655 Changes in 1.94:
 656
 657 * BFD merge is partly done.  Adventurous souls may try giving configure the
 658   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 659   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 660   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 661   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 662   fully merged yet.)
 663
 664 * The 68K opcode table has been split in half.  It should now compile under gcc
 665   without consuming ridiculous amounts of memory.
 666
 667 * A couple data structures have been reduced in size.  This should result in
 668   saving a little bit of space at runtime.
 669
 670 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 671   code provided ROSE format support, which I haven't merged in yet.  (I can
 672   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 673   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 674   coming.
 675
 676 * Support for the Hitachi H8/500 has been added.
 677
 678 * VMS host and target support should be working now, thanks chiefly to Eric
 679   Youngdale.
 680
 681 Changes in 1.93.01:
 682
 683 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 684
 685 * For i386, .align is now power-of-two; was number-of-bytes.
 686
 687 * For m68k, "%" is now accepted before register names.  For COFF format, which
 688   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 689   can be distinguished from the register.
 690
 691 * Last public release was 1.38.  Lots of configuration changes since then, lots
 692   of new CPUs and formats, lots of bugs fixed.
