  20   port.
  21
  22 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  23   .extCoreRegister pseudo-ops that allow an user to define custom
  24   instructions, conditional codes, auxiliary and core registers.
  25
  26 * Add a configure option --enable-elf-stt-common to decide whether ELF
  27   assembler should generate common symbols with the STT_COMMON type by
  28   default.  Default to no.
  29
  30 * New command line option --elf-stt-common= for ELF targets to control
  31   whether to generate common symbols with the STT_COMMON type.
  32
  33 * Add ability to set section flags and types via numeric values for ELF
  34   based targets.
  35
  36 * Add a configure option --enable-x86-relax-relocations to decide whether
  37   x86 assembler should generate relax relocations by default.  Default to
  38   yes, except for x86 Solaris targets older than Solaris 12.

  60   them to contain characters that are not part of valid symbol names in high
  61   level languages.
  62
  63 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  64   previous spelling, -march=armv6zk, is still accepted.

 132
 133 * Add support for the TMS320C6000 (TI C6X) processor family.
 134
 135 * GAS now understands an extended syntax in the .section directive flags
 136   for COFF targets that allows the section's alignment to be specified.  This
 137   feature has also been backported to the 2.20 release series, starting with
 138   2.20.1.
 139
 140 * Add support for the Renesas RX processor.
 141
 142 * New command line option, --compress-debug-sections, which requests
 143   compression of DWARF debug information sections in the relocatable output
 144   file.  Compressed debug sections are supported by readelf, objdump, and
 145   gold, but not currently by Gnu ld.
 146
 147 Changes in 2.20:
 148
 149 * Added support for v850e2 and v850e2v3.
 150
 151 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 152   pseudo op.  It marks the symbol as being globally unique in the entire
 153   process.
 154
 155 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 156   in binary rather than text.
 157
 158 * Add support for common symbol alignment to PE formats.
 159
 160 * Add support for the new discriminator column in the DWARF line table,
 161   with a discriminator operand for the .loc directive.
 162
 163 * Add support for Sunplus score architecture.
 164
 165 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 166   indicate that if the symbol is the target of a relocation, its value should
 167   not be use.  Instead the function should be invoked and its result used as
 168   the value.
 169
 170 * Add support for Lattice Mico32 (lm32) architecture.
 171
 172 * Add support for Xilinx MicroBlaze architecture.
 173
 174 Changes in 2.19:
 175
 176 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 177   tables without runtime relocation.
 178
 179 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 180   adds compatibility with H'00 style hex constants.
 181
 182 * New command line option, -msse-check=[none|error|warning], for x86
 183   targets.
 184
 185 * New sub-option added to the assembler's -a command line switch to
 186   generate a listing output.  The 'g' sub-option will insert into the listing
 187   various information about the assembly, such as assembler version, the
 188   command line options used, and a time stamp.
 189
 190 * New command line option -msse2avx for x86 target to encode SSE
 191   instructions with VEX prefix.
 192
 193 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 194
 195 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 196   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 197   -mnaked-reg and -mold-gcc, for x86 targets.
 198
 199 * Support for generating wide character strings has been added via the new
 200   pseudo ops: .string16, .string32 and .string64.
 201
 202 * Support for SSE5 has been added to the i386 port.
 203
 204 Changes in 2.18:
 205
 206 * The GAS sources are now released under the GPLv3.
 207
 208 * Support for the National Semiconductor CR16 target has been added.
 209
 210 * Added gas .reloc pseudo.  This is a low-level interface for creating
 211   relocations.
 212
 213 * Add support for x86_64 PE+ target.
 214
 215 * Add support for Score target.
 216
 217 Changes in 2.17:
 218
 219 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 220
 221 * Support for ms2 architecture has been added.
 222
 223 * Support for the Z80 processor family has been added.
 224
 225 * Add support for the "@<file>" syntax to the command line, so that extra
 226   switches can be read from <file>.
 227
 228 * The SH target supports a new command line switch --enable-reg-prefix which,
 229   if enabled, will allow register names to be optionally prefixed with a $
 230   character.  This allows register names to be distinguished from label names.
 231
 232 * Macros with a variable number of arguments are now supported. See the
 233   documentation for how this works.
 234
 235 * Added --reduce-memory-overheads switch to reduce the size of the hash
 236   tables used, at the expense of longer assembly times, and
 237   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 238
 239 * Macro names and macro parameter names can now be any identifier that would
 240   also be legal as a symbol elsewhere. For macro parameter names, this is
 241   known to cause problems in certain sources when the respective target uses
 242   characters inconsistently, and thus macro parameter references may no longer
 243   be recognized as such (see the documentation for details).
 244
 245 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 246   for the VAX target in order to be more compatible with the VAX MACRO
 247   assembler.
 248
 249 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 250
 251 Changes in 2.16:
 252
 253 * Redefinition of macros now results in an error.
 254
 255 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 256
 257 * New command line option -munwind-check=[warning|error] for IA64
 258   targets.
 259
 260 * The IA64 port now uses automatic dependency violation removal as its default
 261   mode.
 262
 263 * Port to MAXQ processor contributed by HCL Tech.
 264
 265 * Added support for generating unwind tables for ARM ELF targets.
 266
 267 * Add a -g command line option to generate debug information in the target's
 268   preferred debug format.
 269
 270 * Support for the crx-elf target added.
 271
 272 * Support for the sh-symbianelf target added.
 273
 274 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 275   on pe[i]-i386; required for this target's DWARF 2 support.
 276
 277 * Support for Motorola MCF521x/5249/547x/548x added.
 278
 279 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 280   instrucitons.
 281
 282 * New command line option -mno-shared for MIPS ELF targets.
 283
 284 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 285   added to enter (and leave) alternate macro syntax mode.
 286
 287 Changes in 2.15:
 288
 289 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 290   deprecated and will be removed in a future release.
 291
 292 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 293
 294 * Added support for ARM V6.
 295
 296 * Added support for sh4a and variants.
 297
 298 * Support for Renesas M32R2 added.
 299
 300 * Limited support for Mapping Symbols as specified in the ARM ELF
 301   specification has been added to the arm assembler.
 302
 303 * On ARM architectures, added a new gas directive ".unreq" that undoes
 304   definitions created by ".req".
 305
 306 * Support for Motorola ColdFire MCF528x added.
 307
 308 * Added --gstabs+ switch to enable the generation of STABS debug format
 309   information with GNU extensions.
 310
 311 * Added support for MIPS64 Release 2.
 312
 313 * Added support for v850e1.
 314
 315 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 316   multiple nop instructions used for alignment within code sections
 317   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 318   switch disables the optimization.
 319
 320 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 321   existing -non_shared option.
 322
 323 Changes in 2.14:
 324
 325 * Added support for MIPS32 Release 2.
 326
 327 * Added support for Xtensa architecture.
 328
 329 * Support for Intel's iWMMXt processor (an ARM variant) added.
 330
 331 * An assembler test generator has been contributed and an example file that
 332   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 333
 334 * Support for SH2E added.
 335
 336 * GASP has now been removed.
 337
 338 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 339   DSP's contributed by Michael Hayes and Svein E. Seldal.
 340
 341 * Support for the Ubicom IP2xxx microcontroller added.
 342
 343 Changes in 2.13:
 344
 345 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 346   and FR500 included.
 347
 348 * Support for DLX processor added.
 349
 350 * GASP has now been deprecated and will be removed in a future release.  Use
 351   the macro facilities in GAS instead.
 352
 353 * GASP now correctly parses floating point numbers. Unless the base is
 354   explicitly specified, they are interpreted as decimal numbers regardless of
 355   the currently specified base.
 356
 357 Changes in 2.12:
 358
 359 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 360
 361 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 362
 363 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 364   specifying the target instruction set.  The old method of specifying the
 365   target processor has been deprecated, but is still accepted for
 366   compatibility.
 367
 368 * Support for the VFP floating-point instruction set has been added to
 369   the ARM assembler.
 370
 371 * New psuedo op: .incbin to include a set of binary data at a given point
 372   in the assembly.  Contributed by Anders Norlander.
 373
 374 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 375   but still works for compatability.
 376
 377 * The MIPS assembler no longer issues a warning by default when it
 378   generates a nop instruction from a macro. The new command line option
 379   -n will turn on the warning.
 380
 381 Changes in 2.11:
 382
 383 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 384
 385 * x86 gas now supports the full Pentium4 instruction set.
 386
 387 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 388
 389 * Support for Motorola 68HC11 and 68HC12.
 390
 391 * Support for Texas Instruments TMS320C54x (tic54x).
 392
 393 * Support for IA-64.
 394
 395 * Support for i860, by Jason Eckhardt.
 396
 397 * Support for CRIS (Axis Communications ETRAX series).
 398
 399 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 400
 401 * x86 gas -q command line option quietens warnings about register size changes
 402   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 403   translating various deprecated floating point instructions.
 404
 405 Changes in 2.10:
 406
 407 * Support for the ARM msr instruction was changed to only allow an immediate
 408   operand when altering the flags field.
 409
 410 * Support for ATMEL AVR.
 411
 412 * Support for IBM 370 ELF.  Somewhat experimental.
 413
 414 * Support for numbers with suffixes.
 415
 416 * Added support for breaking to the end of repeat loops.
 417
 418 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 419
 420 * New .elseif pseudo-op added.
 421
 422 * New --fatal-warnings option.
 423
 424 * picoJava architecture support added.
 425
 426 * Motorola MCore 210 processor support added.
 427
 428 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 429   assembly programs with intel syntax.
 430
 431 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 432
 433 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 434
 435 * Full 16-bit mode support for i386.
 436
 437 * Greatly improved instruction operand checking for i386.  This change will
 438   produce errors or warnings on incorrect assembly code that previous versions
 439   of gas accepted.  If you get unexpected messages from code that worked with
 440   older versions of gas, please double check the code before reporting a bug.
 441
 442 * Weak symbol support added for COFF targets.
 443
 444 * Mitsubishi D30V support added.
 445
 446 * Texas Instruments c80 (tms320c80) support added.
 447
 448 * i960 ELF support added.
 449
 450 * ARM ELF support added.
 451
 452 Changes in 2.9:
 453
 454 * Texas Instruments c30 (tms320c30) support added.
 455
 456 * The assembler now optimizes the exception frame information generated by egcs
 457   and gcc 2.8.  The new --traditional-format option disables this optimization.
 458
 459 * Added --gstabs option to generate stabs debugging information.
 460
 461 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 462   listing.
 463
 464 * Added -MD option to print dependencies.
 465
 466 Changes in 2.8:
 467
 468 * BeOS support added.
 469
 470 * MIPS16 support added.
 471
 472 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 473
 474 * Alpha/VMS support added.
 475
 476 * m68k options --base-size-default-16, --base-size-default-32,
 477   --disp-size-default-16, and --disp-size-default-32 added.
 478
 479 * The alignment directives now take an optional third argument, which is the
 480   maximum number of bytes to skip.  If doing the alignment would require
 481   skipping more than the given number of bytes, the alignment is not done at
 482   all.
 483
 484 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 485
 486 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 487   conditionals in listings.
 488
 489 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 490   the symbol is already defined.
 491
 492 Changes in 2.7:
 493
 494 * The PowerPC assembler now allows the use of symbolic register names (r0,
 495   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 496   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 497   added.
 498
 499 * Alpha Linux (ELF) support added.
 500
 501 * PowerPC ELF support added.
 502
 503 * m68k Linux (ELF) support added.
 504
 505 * i960 Hx/Jx support added.
 506
 507 * i386/PowerPC gnu-win32 support added.
 508
 509 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 510   default is to build COFF-only support.  To get a set of tools that generate
 511   ELF (they'll understand both COFF and ELF), you must configure with
 512   target=i386-unknown-sco3.2v5elf.
 513
 514 * m88k-motorola-sysv3* support added.
 515
 516 Changes in 2.6:
 517
 518 * Gas now directly supports macros, without requiring GASP.
 519
 520 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 521   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 522   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 523
 524 * Added --defsym SYM=VALUE option.
 525
 526 * Added -mips4 support to MIPS assembler.
 527
 528 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 529
 530 Changes in 2.4:
 531
 532 * Converted this directory to use an autoconf-generated configure script.
 533
 534 * ARM support, from Richard Earnshaw.
 535
 536 * Updated VMS support, from Pat Rankin, including considerably improved
 537   debugging support.
 538
 539 * Support for the control registers in the 68060.
 540
 541 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 542   provide for possible future gcc changes, for targets where gas provides some
 543   features not available in the native assembler.  If the native assembler is
 544   used, it should become obvious pretty quickly what the problem is.
 545
 546 * Usage message is available with "--help".
 547
 548 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 549   also, but didn't get into the NEWS file.)
 550
 551 * Weak symbol support for a.out.
 552
 553 * A bug in the listing code which could cause an infinite loop has been fixed.
 554   Bugs in listings when generating a COFF object file have also been fixed.
 555
 556 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 557   Paul Kranenburg.
 558
 559 * Improved Alpha support.  Immediate constants can have a much larger range
 560   now. Support for the 21164 has been contributed by Digital.
 561
 562 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 563
 564 Changes in 2.3:
 565
 566 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 567
 568 * RS/6000 and PowerPC support by Ian Taylor.
 569
 570 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 571   based on mail received from various people.  The `-h#' option should work
 572   again too.
 573
 574 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 575   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 576   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 577   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 578   in the "dist" directory.
 579
 580 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 581   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 582   currently required for BSD 4.3 builds.)
 583
 584 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 585   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 586   the alpha-a.out support is pretty badly mangled, and much of it removed;
 587   making it work will require rewriting it as BFD support for the format anyways.
 588
 589 * Irix 5 support.
 590
 591 * The test suites have been fixed up a bit, so that they should work with a
 592   couple different versions of expect and dejagnu.
 593
 594 * Symbols' values are now handled internally as expressions, permitting more
 595   flexibility in evaluating them in some cases.  Some details of relocation
 596   handling have also changed, and simple constant pool management has been
 597   added, to make the Alpha port easier.
 598
 599 * New option "--statistics" for printing out program run times.  This is
 600   intended to be used with the gcc "-Q" option, which prints out times spent in
 601   various phases of compilation.  (You should be able to get all of them
 602   printed out with "gcc -Q -Wa,--statistics", I think.)
 603
 604 Changes in 2.2:
 605
 606 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 607
 608 * Configurations that are still in development (and therefore are convenient to
 609   have listed in configure.in) still get rejected without a minor change to
 610   gas/Makefile.in, so people not doing development work shouldn't get the
 611   impression that support for such configurations is actually believed to be
 612   reliable.
 613
 614 * The program name (usually "as") is printed when a fatal error message is
 615   displayed.  This should prevent some confusion about the source of occasional
 616   messages about "internal errors".
 617
 618 * ELF support is falling into place.  Support for the 386 should be working.
 619   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 620
 621 * Symbol values are maintained as expressions instead of being immediately
 622   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 623   more complex calculations involving symbols whose values are not alreadey
 624   known.
 625
 626 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 627   If any stabs directives are seen in the source, GAS will create two new
 628   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 629   section is nearly identical to the a.out symbol format, and .stabstr is
 630   its string table.  For this to be useful, you must have configured GCC
 631   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 632   that can use the stab sections (4.11 or later).
 633
 634 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 635   support is in progress.
 636
 637 Changes in 2.1:
 638
 639 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 640   incorporated, but not well tested yet.
 641
 642 * Altered the opcode table split for m68k; it should require less VM to compile
 643   with gcc now.
 644
 645 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 646   suggested by Ronald Cole.
 647
 648 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 649   includes improved ELF support, which I've started adapting for SPARC Solaris
 650   2.x.  Integration isn't completely, so it probably won't work.
 651
 652 * HP9000/300 support, donated by HP, has been merged in.
 653
 654 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 655
 656 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 657
 658 * Test suite framework is starting to become reasonable.
 659
 660 Changes in 2.0:
 661
 662 * Mostly bug fixes.
 663
 664 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 665
 666 Changes in 1.94:
 667
 668 * BFD merge is partly done.  Adventurous souls may try giving configure the
 669   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 670   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 671   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 672   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 673   fully merged yet.)
 674
 675 * The 68K opcode table has been split in half.  It should now compile under gcc
 676   without consuming ridiculous amounts of memory.
 677
 678 * A couple data structures have been reduced in size.  This should result in
 679   saving a little bit of space at runtime.
 680
 681 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 682   code provided ROSE format support, which I haven't merged in yet.  (I can
 683   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 684   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 685   coming.
 686
 687 * Support for the Hitachi H8/500 has been added.
 688
 689 * VMS host and target support should be working now, thanks chiefly to Eric
 690   Youngdale.
 691
 692 Changes in 1.93.01:
 693
 694 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 695
 696 * For i386, .align is now power-of-two; was number-of-bytes.
 697
 698 * For m68k, "%" is now accepted before register names.  For COFF format, which
 699   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 700   can be distinguished from the register.
 701
 702 * Last public release was 1.38.  Lots of configuration changes since then, lots
 703   of new CPUs and formats, lots of bugs fixed.
