   8
   9 * Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
  10
  11 * Add --no-pad-sections to stop the assembler from padding the end of output
  12   sections up to their alignment boundary.
  13
  14 * Support for the ARMv8-M architecture has been added to the ARM port.  Support
  15   for the ARMv8-M Security and DSP Extensions has also been added to the ARM
  16   port.
  17
  18 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  19   .extCoreRegister pseudo-ops that allow an user to define custom
  20   instructions, conditional codes, auxiliary and core registers.
  21
  22 * Add a configure option --enable-elf-stt-common to decide whether ELF
  23   assembler should generate common symbols with the STT_COMMON type by
  24   default.  Default to no.
  25
  26 * New command line option --elf-stt-common= for ELF targets to control
  27   whether to generate common symbols with the STT_COMMON type.
  28
  29 * Add ability to set section flags and types via numeric values for ELF
  30   based targets.
  31
  32 * Add a configure option --enable-x86-relax-relocations to decide whether
  33   x86 assembler should generate relax relocations by default.  Default to
  34   yes, except for x86 Solaris targets older than Solaris 12.
  35
  36 * New command line option -mrelax-relocations= for x86 target to control
  37   whether to generate relax relocations.
  38

  41
  42 * Add assembly-time relaxation option for ARC cpus.
  43
  44 * Add --with-cpu=TYPE configure option for ARC gas.  This allows the default
  45   cpu type to be adjusted at configure time.
  46
  47 Changes in 2.26:
  48
  49 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  50   decide whether DWARF debug sections should be compressed by default.

  53   assembler support for Argonaut RISC architectures.
  54
  55 * Symbol and label names can now be enclosed in double quotes (") which allows
  56   them to contain characters that are not part of valid symbol names in high
  57   level languages.
  58
  59 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  60   previous spelling, -march=armv6zk, is still accepted.

 128
 129 * Add support for the TMS320C6000 (TI C6X) processor family.
 130
 131 * GAS now understands an extended syntax in the .section directive flags
 132   for COFF targets that allows the section's alignment to be specified.  This
 133   feature has also been backported to the 2.20 release series, starting with
 134   2.20.1.
 135
 136 * Add support for the Renesas RX processor.
 137
 138 * New command line option, --compress-debug-sections, which requests
 139   compression of DWARF debug information sections in the relocatable output
 140   file.  Compressed debug sections are supported by readelf, objdump, and
 141   gold, but not currently by Gnu ld.
 142
 143 Changes in 2.20:
 144
 145 * Added support for v850e2 and v850e2v3.
 146
 147 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 148   pseudo op.  It marks the symbol as being globally unique in the entire
 149   process.
 150
 151 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 152   in binary rather than text.
 153
 154 * Add support for common symbol alignment to PE formats.
 155
 156 * Add support for the new discriminator column in the DWARF line table,
 157   with a discriminator operand for the .loc directive.
 158
 159 * Add support for Sunplus score architecture.
 160
 161 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 162   indicate that if the symbol is the target of a relocation, its value should
 163   not be use.  Instead the function should be invoked and its result used as
 164   the value.
 165
 166 * Add support for Lattice Mico32 (lm32) architecture.
 167
 168 * Add support for Xilinx MicroBlaze architecture.
 169
 170 Changes in 2.19:
 171
 172 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 173   tables without runtime relocation.
 174
 175 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 176   adds compatibility with H'00 style hex constants.
 177
 178 * New command line option, -msse-check=[none|error|warning], for x86
 179   targets.
 180
 181 * New sub-option added to the assembler's -a command line switch to
 182   generate a listing output.  The 'g' sub-option will insert into the listing
 183   various information about the assembly, such as assembler version, the
 184   command line options used, and a time stamp.
 185
 186 * New command line option -msse2avx for x86 target to encode SSE
 187   instructions with VEX prefix.
 188
 189 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 190
 191 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 192   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 193   -mnaked-reg and -mold-gcc, for x86 targets.
 194
 195 * Support for generating wide character strings has been added via the new
 196   pseudo ops: .string16, .string32 and .string64.
 197
 198 * Support for SSE5 has been added to the i386 port.
 199
 200 Changes in 2.18:
 201
 202 * The GAS sources are now released under the GPLv3.
 203
 204 * Support for the National Semiconductor CR16 target has been added.
 205
 206 * Added gas .reloc pseudo.  This is a low-level interface for creating
 207   relocations.
 208
 209 * Add support for x86_64 PE+ target.
 210
 211 * Add support for Score target.
 212
 213 Changes in 2.17:
 214
 215 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 216
 217 * Support for ms2 architecture has been added.
 218
 219 * Support for the Z80 processor family has been added.
 220
 221 * Add support for the "@<file>" syntax to the command line, so that extra
 222   switches can be read from <file>.
 223
 224 * The SH target supports a new command line switch --enable-reg-prefix which,
 225   if enabled, will allow register names to be optionally prefixed with a $
 226   character.  This allows register names to be distinguished from label names.
 227
 228 * Macros with a variable number of arguments are now supported. See the
 229   documentation for how this works.
 230
 231 * Added --reduce-memory-overheads switch to reduce the size of the hash
 232   tables used, at the expense of longer assembly times, and
 233   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 234
 235 * Macro names and macro parameter names can now be any identifier that would
 236   also be legal as a symbol elsewhere. For macro parameter names, this is
 237   known to cause problems in certain sources when the respective target uses
 238   characters inconsistently, and thus macro parameter references may no longer
 239   be recognized as such (see the documentation for details).
 240
 241 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 242   for the VAX target in order to be more compatible with the VAX MACRO
 243   assembler.
 244
 245 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 246
 247 Changes in 2.16:
 248
 249 * Redefinition of macros now results in an error.
 250
 251 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 252
 253 * New command line option -munwind-check=[warning|error] for IA64
 254   targets.
 255
 256 * The IA64 port now uses automatic dependency violation removal as its default
 257   mode.
 258
 259 * Port to MAXQ processor contributed by HCL Tech.
 260
 261 * Added support for generating unwind tables for ARM ELF targets.
 262
 263 * Add a -g command line option to generate debug information in the target's
 264   preferred debug format.
 265
 266 * Support for the crx-elf target added.
 267
 268 * Support for the sh-symbianelf target added.
 269
 270 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 271   on pe[i]-i386; required for this target's DWARF 2 support.
 272
 273 * Support for Motorola MCF521x/5249/547x/548x added.
 274
 275 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 276   instrucitons.
 277
 278 * New command line option -mno-shared for MIPS ELF targets.
 279
 280 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 281   added to enter (and leave) alternate macro syntax mode.
 282
 283 Changes in 2.15:
 284
 285 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 286   deprecated and will be removed in a future release.
 287
 288 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 289
 290 * Added support for ARM V6.
 291
 292 * Added support for sh4a and variants.
 293
 294 * Support for Renesas M32R2 added.
 295
 296 * Limited support for Mapping Symbols as specified in the ARM ELF
 297   specification has been added to the arm assembler.
 298
 299 * On ARM architectures, added a new gas directive ".unreq" that undoes
 300   definitions created by ".req".
 301
 302 * Support for Motorola ColdFire MCF528x added.
 303
 304 * Added --gstabs+ switch to enable the generation of STABS debug format
 305   information with GNU extensions.
 306
 307 * Added support for MIPS64 Release 2.
 308
 309 * Added support for v850e1.
 310
 311 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 312   multiple nop instructions used for alignment within code sections
 313   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 314   switch disables the optimization.
 315
 316 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 317   existing -non_shared option.
 318
 319 Changes in 2.14:
 320
 321 * Added support for MIPS32 Release 2.
 322
 323 * Added support for Xtensa architecture.
 324
 325 * Support for Intel's iWMMXt processor (an ARM variant) added.
 326
 327 * An assembler test generator has been contributed and an example file that
 328   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 329
 330 * Support for SH2E added.
 331
 332 * GASP has now been removed.
 333
 334 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 335   DSP's contributed by Michael Hayes and Svein E. Seldal.
 336
 337 * Support for the Ubicom IP2xxx microcontroller added.
 338
 339 Changes in 2.13:
 340
 341 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 342   and FR500 included.
 343
 344 * Support for DLX processor added.
 345
 346 * GASP has now been deprecated and will be removed in a future release.  Use
 347   the macro facilities in GAS instead.
 348
 349 * GASP now correctly parses floating point numbers. Unless the base is
 350   explicitly specified, they are interpreted as decimal numbers regardless of
 351   the currently specified base.
 352
 353 Changes in 2.12:
 354
 355 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 356
 357 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 358
 359 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 360   specifying the target instruction set.  The old method of specifying the
 361   target processor has been deprecated, but is still accepted for
 362   compatibility.
 363
 364 * Support for the VFP floating-point instruction set has been added to
 365   the ARM assembler.
 366
 367 * New psuedo op: .incbin to include a set of binary data at a given point
 368   in the assembly.  Contributed by Anders Norlander.
 369
 370 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 371   but still works for compatability.
 372
 373 * The MIPS assembler no longer issues a warning by default when it
 374   generates a nop instruction from a macro. The new command line option
 375   -n will turn on the warning.
 376
 377 Changes in 2.11:
 378
 379 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 380
 381 * x86 gas now supports the full Pentium4 instruction set.
 382
 383 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 384
 385 * Support for Motorola 68HC11 and 68HC12.
 386
 387 * Support for Texas Instruments TMS320C54x (tic54x).
 388
 389 * Support for IA-64.
 390
 391 * Support for i860, by Jason Eckhardt.
 392
 393 * Support for CRIS (Axis Communications ETRAX series).
 394
 395 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 396
 397 * x86 gas -q command line option quietens warnings about register size changes
 398   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 399   translating various deprecated floating point instructions.
 400
 401 Changes in 2.10:
 402
 403 * Support for the ARM msr instruction was changed to only allow an immediate
 404   operand when altering the flags field.
 405
 406 * Support for ATMEL AVR.
 407
 408 * Support for IBM 370 ELF.  Somewhat experimental.
 409
 410 * Support for numbers with suffixes.
 411
 412 * Added support for breaking to the end of repeat loops.
 413
 414 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 415
 416 * New .elseif pseudo-op added.
 417
 418 * New --fatal-warnings option.
 419
 420 * picoJava architecture support added.
 421
 422 * Motorola MCore 210 processor support added.
 423
 424 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 425   assembly programs with intel syntax.
 426
 427 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 428
 429 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 430
 431 * Full 16-bit mode support for i386.
 432
 433 * Greatly improved instruction operand checking for i386.  This change will
 434   produce errors or warnings on incorrect assembly code that previous versions
 435   of gas accepted.  If you get unexpected messages from code that worked with
 436   older versions of gas, please double check the code before reporting a bug.
 437
 438 * Weak symbol support added for COFF targets.
 439
 440 * Mitsubishi D30V support added.
 441
 442 * Texas Instruments c80 (tms320c80) support added.
 443
 444 * i960 ELF support added.
 445
 446 * ARM ELF support added.
 447
 448 Changes in 2.9:
 449
 450 * Texas Instruments c30 (tms320c30) support added.
 451
 452 * The assembler now optimizes the exception frame information generated by egcs
 453   and gcc 2.8.  The new --traditional-format option disables this optimization.
 454
 455 * Added --gstabs option to generate stabs debugging information.
 456
 457 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 458   listing.
 459
 460 * Added -MD option to print dependencies.
 461
 462 Changes in 2.8:
 463
 464 * BeOS support added.
 465
 466 * MIPS16 support added.
 467
 468 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 469
 470 * Alpha/VMS support added.
 471
 472 * m68k options --base-size-default-16, --base-size-default-32,
 473   --disp-size-default-16, and --disp-size-default-32 added.
 474
 475 * The alignment directives now take an optional third argument, which is the
 476   maximum number of bytes to skip.  If doing the alignment would require
 477   skipping more than the given number of bytes, the alignment is not done at
 478   all.
 479
 480 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 481
 482 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 483   conditionals in listings.
 484
 485 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 486   the symbol is already defined.
 487
 488 Changes in 2.7:
 489
 490 * The PowerPC assembler now allows the use of symbolic register names (r0,
 491   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 492   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 493   added.
 494
 495 * Alpha Linux (ELF) support added.
 496
 497 * PowerPC ELF support added.
 498
 499 * m68k Linux (ELF) support added.
 500
 501 * i960 Hx/Jx support added.
 502
 503 * i386/PowerPC gnu-win32 support added.
 504
 505 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 506   default is to build COFF-only support.  To get a set of tools that generate
 507   ELF (they'll understand both COFF and ELF), you must configure with
 508   target=i386-unknown-sco3.2v5elf.
 509
 510 * m88k-motorola-sysv3* support added.
 511
 512 Changes in 2.6:
 513
 514 * Gas now directly supports macros, without requiring GASP.
 515
 516 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 517   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 518   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 519
 520 * Added --defsym SYM=VALUE option.
 521
 522 * Added -mips4 support to MIPS assembler.
 523
 524 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 525
 526 Changes in 2.4:
 527
 528 * Converted this directory to use an autoconf-generated configure script.
 529
 530 * ARM support, from Richard Earnshaw.
 531
 532 * Updated VMS support, from Pat Rankin, including considerably improved
 533   debugging support.
 534
 535 * Support for the control registers in the 68060.
 536
 537 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 538   provide for possible future gcc changes, for targets where gas provides some
 539   features not available in the native assembler.  If the native assembler is
 540   used, it should become obvious pretty quickly what the problem is.
 541
 542 * Usage message is available with "--help".
 543
 544 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 545   also, but didn't get into the NEWS file.)
 546
 547 * Weak symbol support for a.out.
 548
 549 * A bug in the listing code which could cause an infinite loop has been fixed.
 550   Bugs in listings when generating a COFF object file have also been fixed.
 551
 552 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 553   Paul Kranenburg.
 554
 555 * Improved Alpha support.  Immediate constants can have a much larger range
 556   now. Support for the 21164 has been contributed by Digital.
 557
 558 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 559
 560 Changes in 2.3:
 561
 562 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 563
 564 * RS/6000 and PowerPC support by Ian Taylor.
 565
 566 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 567   based on mail received from various people.  The `-h#' option should work
 568   again too.
 569
 570 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 571   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 572   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 573   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 574   in the "dist" directory.
 575
 576 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 577   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 578   currently required for BSD 4.3 builds.)
 579
 580 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 581   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 582   the alpha-a.out support is pretty badly mangled, and much of it removed;
 583   making it work will require rewriting it as BFD support for the format anyways.
 584
 585 * Irix 5 support.
 586
 587 * The test suites have been fixed up a bit, so that they should work with a
 588   couple different versions of expect and dejagnu.
 589
 590 * Symbols' values are now handled internally as expressions, permitting more
 591   flexibility in evaluating them in some cases.  Some details of relocation
 592   handling have also changed, and simple constant pool management has been
 593   added, to make the Alpha port easier.
 594
 595 * New option "--statistics" for printing out program run times.  This is
 596   intended to be used with the gcc "-Q" option, which prints out times spent in
 597   various phases of compilation.  (You should be able to get all of them
 598   printed out with "gcc -Q -Wa,--statistics", I think.)
 599
 600 Changes in 2.2:
 601
 602 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 603
 604 * Configurations that are still in development (and therefore are convenient to
 605   have listed in configure.in) still get rejected without a minor change to
 606   gas/Makefile.in, so people not doing development work shouldn't get the
 607   impression that support for such configurations is actually believed to be
 608   reliable.
 609
 610 * The program name (usually "as") is printed when a fatal error message is
 611   displayed.  This should prevent some confusion about the source of occasional
 612   messages about "internal errors".
 613
 614 * ELF support is falling into place.  Support for the 386 should be working.
 615   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 616
 617 * Symbol values are maintained as expressions instead of being immediately
 618   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 619   more complex calculations involving symbols whose values are not alreadey
 620   known.
 621
 622 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 623   If any stabs directives are seen in the source, GAS will create two new
 624   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 625   section is nearly identical to the a.out symbol format, and .stabstr is
 626   its string table.  For this to be useful, you must have configured GCC
 627   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 628   that can use the stab sections (4.11 or later).
 629
 630 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 631   support is in progress.
 632
 633 Changes in 2.1:
 634
 635 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 636   incorporated, but not well tested yet.
 637
 638 * Altered the opcode table split for m68k; it should require less VM to compile
 639   with gcc now.
 640
 641 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 642   suggested by Ronald Cole.
 643
 644 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 645   includes improved ELF support, which I've started adapting for SPARC Solaris
 646   2.x.  Integration isn't completely, so it probably won't work.
 647
 648 * HP9000/300 support, donated by HP, has been merged in.
 649
 650 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 651
 652 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 653
 654 * Test suite framework is starting to become reasonable.
 655
 656 Changes in 2.0:
 657
 658 * Mostly bug fixes.
 659
 660 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 661
 662 Changes in 1.94:
 663
 664 * BFD merge is partly done.  Adventurous souls may try giving configure the
 665   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 666   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 667   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 668   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 669   fully merged yet.)
 670
 671 * The 68K opcode table has been split in half.  It should now compile under gcc
 672   without consuming ridiculous amounts of memory.
 673
 674 * A couple data structures have been reduced in size.  This should result in
 675   saving a little bit of space at runtime.
 676
 677 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 678   code provided ROSE format support, which I haven't merged in yet.  (I can
 679   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 680   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 681   coming.
 682
 683 * Support for the Hitachi H8/500 has been added.
 684
 685 * VMS host and target support should be working now, thanks chiefly to Eric
 686   Youngdale.
 687
 688 Changes in 1.93.01:
 689
 690 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 691
 692 * For i386, .align is now power-of-two; was number-of-bytes.
 693
 694 * For m68k, "%" is now accepted before register names.  For COFF format, which
 695   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 696   can be distinguished from the register.
 697
 698 * Last public release was 1.38.  Lots of configuration changes since then, lots
 699   of new CPUs and formats, lots of bugs fixed.
