   2 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
   3   .extCoreRegister pseudo-ops that allow an user to define custom
   4   instructions, conditional codes, auxiliary and core registers.
   5
   6 * Add a configure option --enable-elf-stt-common to decide whether ELF
   7   assembler should generate common symbols with the STT_COMMON type by
   8   default.  Default to no.
   9
  10 * New command line option --elf-stt-common= for ELF targets to control
  11   whether to generate common symbols with the STT_COMMON type.
  12
  13 * Add ability to set section flags and types via numeric values for ELF
  14   based targets.
  15
  16 * Add a configure option --enable-x86-relax-relocations to decide whether
  17   x86 assembler should generate relax relocations by default.  Default to
  18   yes, except for x86 Solaris targets older than Solaris 12.
  19
  20 * New command line option -mrelax-relocations= for x86 target to control
  21   whether to generate relax relocations.
  22
  23 * New command line option -mfence-as-lock-add=yes for x86 target to encode
  24   lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
  25
  26 * Add assembly-time relaxation option for ARC cpus.
  27
  28 Changes in 2.26:
  29
  30 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  31   decide whether DWARF debug sections should be compressed by default.

  33 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  34   assembler support for Argonaut RISC architectures.
  35
  36 * Symbol and label names can now be enclosed in double quotes (") which allows
  37   them to contain characters that are not part of valid symbol names in high
  38   level languages.
  39
  40 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  41   previous spelling, -march=armv6zk, is still accepted.
  42
  43 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  44   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  45   extensions has also been added to the Aarch64 port.

  73   generation of DWARF .debug_line sections.
  74
  75 * Add support for Altera Nios II.
  76
  77 * Add support for the Imagination Technologies Meta processor.
  78
  79 * Add support for the v850e3v5.
  80
  81 * Remove assembler support for MIPS ECOFF targets.
  82

 109
 110 * Add support for the TMS320C6000 (TI C6X) processor family.
 111
 112 * GAS now understands an extended syntax in the .section directive flags
 113   for COFF targets that allows the section's alignment to be specified.  This
 114   feature has also been backported to the 2.20 release series, starting with
 115   2.20.1.
 116
 117 * Add support for the Renesas RX processor.
 118
 119 * New command line option, --compress-debug-sections, which requests
 120   compression of DWARF debug information sections in the relocatable output
 121   file.  Compressed debug sections are supported by readelf, objdump, and
 122   gold, but not currently by Gnu ld.
 123
 124 Changes in 2.20:
 125
 126 * Added support for v850e2 and v850e2v3.
 127
 128 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 129   pseudo op.  It marks the symbol as being globally unique in the entire
 130   process.
 131
 132 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 133   in binary rather than text.
 134
 135 * Add support for common symbol alignment to PE formats.
 136
 137 * Add support for the new discriminator column in the DWARF line table,
 138   with a discriminator operand for the .loc directive.
 139
 140 * Add support for Sunplus score architecture.
 141
 142 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 143   indicate that if the symbol is the target of a relocation, its value should
 144   not be use.  Instead the function should be invoked and its result used as
 145   the value.
 146
 147 * Add support for Lattice Mico32 (lm32) architecture.
 148
 149 * Add support for Xilinx MicroBlaze architecture.
 150
 151 Changes in 2.19:
 152
 153 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 154   tables without runtime relocation.
 155
 156 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 157   adds compatibility with H'00 style hex constants.
 158
 159 * New command line option, -msse-check=[none|error|warning], for x86
 160   targets.
 161
 162 * New sub-option added to the assembler's -a command line switch to
 163   generate a listing output.  The 'g' sub-option will insert into the listing
 164   various information about the assembly, such as assembler version, the
 165   command line options used, and a time stamp.
 166
 167 * New command line option -msse2avx for x86 target to encode SSE
 168   instructions with VEX prefix.
 169
 170 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 171
 172 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 173   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 174   -mnaked-reg and -mold-gcc, for x86 targets.
 175
 176 * Support for generating wide character strings has been added via the new
 177   pseudo ops: .string16, .string32 and .string64.
 178
 179 * Support for SSE5 has been added to the i386 port.
 180
 181 Changes in 2.18:
 182
 183 * The GAS sources are now released under the GPLv3.
 184
 185 * Support for the National Semiconductor CR16 target has been added.
 186
 187 * Added gas .reloc pseudo.  This is a low-level interface for creating
 188   relocations.
 189
 190 * Add support for x86_64 PE+ target.
 191
 192 * Add support for Score target.
 193
 194 Changes in 2.17:
 195
 196 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 197
 198 * Support for ms2 architecture has been added.
 199
 200 * Support for the Z80 processor family has been added.
 201
 202 * Add support for the "@<file>" syntax to the command line, so that extra
 203   switches can be read from <file>.
 204
 205 * The SH target supports a new command line switch --enable-reg-prefix which,
 206   if enabled, will allow register names to be optionally prefixed with a $
 207   character.  This allows register names to be distinguished from label names.
 208
 209 * Macros with a variable number of arguments are now supported. See the
 210   documentation for how this works.
 211
 212 * Added --reduce-memory-overheads switch to reduce the size of the hash
 213   tables used, at the expense of longer assembly times, and
 214   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 215
 216 * Macro names and macro parameter names can now be any identifier that would
 217   also be legal as a symbol elsewhere. For macro parameter names, this is
 218   known to cause problems in certain sources when the respective target uses
 219   characters inconsistently, and thus macro parameter references may no longer
 220   be recognized as such (see the documentation for details).
 221
 222 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 223   for the VAX target in order to be more compatible with the VAX MACRO
 224   assembler.
 225
 226 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 227
 228 Changes in 2.16:
 229
 230 * Redefinition of macros now results in an error.
 231
 232 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 233
 234 * New command line option -munwind-check=[warning|error] for IA64
 235   targets.
 236
 237 * The IA64 port now uses automatic dependency violation removal as its default
 238   mode.
 239
 240 * Port to MAXQ processor contributed by HCL Tech.
 241
 242 * Added support for generating unwind tables for ARM ELF targets.
 243
 244 * Add a -g command line option to generate debug information in the target's
 245   preferred debug format.
 246
 247 * Support for the crx-elf target added.
 248
 249 * Support for the sh-symbianelf target added.
 250
 251 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 252   on pe[i]-i386; required for this target's DWARF 2 support.
 253
 254 * Support for Motorola MCF521x/5249/547x/548x added.
 255
 256 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 257   instrucitons.
 258
 259 * New command line option -mno-shared for MIPS ELF targets.
 260
 261 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 262   added to enter (and leave) alternate macro syntax mode.
 263
 264 Changes in 2.15:
 265
 266 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 267   deprecated and will be removed in a future release.
 268
 269 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 270
 271 * Added support for ARM V6.
 272
 273 * Added support for sh4a and variants.
 274
 275 * Support for Renesas M32R2 added.
 276
 277 * Limited support for Mapping Symbols as specified in the ARM ELF
 278   specification has been added to the arm assembler.
 279
 280 * On ARM architectures, added a new gas directive ".unreq" that undoes
 281   definitions created by ".req".
 282
 283 * Support for Motorola ColdFire MCF528x added.
 284
 285 * Added --gstabs+ switch to enable the generation of STABS debug format
 286   information with GNU extensions.
 287
 288 * Added support for MIPS64 Release 2.
 289
 290 * Added support for v850e1.
 291
 292 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 293   multiple nop instructions used for alignment within code sections
 294   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 295   switch disables the optimization.
 296
 297 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 298   existing -non_shared option.
 299
 300 Changes in 2.14:
 301
 302 * Added support for MIPS32 Release 2.
 303
 304 * Added support for Xtensa architecture.
 305
 306 * Support for Intel's iWMMXt processor (an ARM variant) added.
 307
 308 * An assembler test generator has been contributed and an example file that
 309   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 310
 311 * Support for SH2E added.
 312
 313 * GASP has now been removed.
 314
 315 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 316   DSP's contributed by Michael Hayes and Svein E. Seldal.
 317
 318 * Support for the Ubicom IP2xxx microcontroller added.
 319
 320 Changes in 2.13:
 321
 322 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 323   and FR500 included.
 324
 325 * Support for DLX processor added.
 326
 327 * GASP has now been deprecated and will be removed in a future release.  Use
 328   the macro facilities in GAS instead.
 329
 330 * GASP now correctly parses floating point numbers. Unless the base is
 331   explicitly specified, they are interpreted as decimal numbers regardless of
 332   the currently specified base.
 333
 334 Changes in 2.12:
 335
 336 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 337
 338 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 339
 340 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 341   specifying the target instruction set.  The old method of specifying the
 342   target processor has been deprecated, but is still accepted for
 343   compatibility.
 344
 345 * Support for the VFP floating-point instruction set has been added to
 346   the ARM assembler.
 347
 348 * New psuedo op: .incbin to include a set of binary data at a given point
 349   in the assembly.  Contributed by Anders Norlander.
 350
 351 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 352   but still works for compatability.
 353
 354 * The MIPS assembler no longer issues a warning by default when it
 355   generates a nop instruction from a macro. The new command line option
 356   -n will turn on the warning.
 357
 358 Changes in 2.11:
 359
 360 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 361
 362 * x86 gas now supports the full Pentium4 instruction set.
 363
 364 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 365
 366 * Support for Motorola 68HC11 and 68HC12.
 367
 368 * Support for Texas Instruments TMS320C54x (tic54x).
 369
 370 * Support for IA-64.
 371
 372 * Support for i860, by Jason Eckhardt.
 373
 374 * Support for CRIS (Axis Communications ETRAX series).
 375
 376 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 377
 378 * x86 gas -q command line option quietens warnings about register size changes
 379   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 380   translating various deprecated floating point instructions.
 381
 382 Changes in 2.10:
 383
 384 * Support for the ARM msr instruction was changed to only allow an immediate
 385   operand when altering the flags field.
 386
 387 * Support for ATMEL AVR.
 388
 389 * Support for IBM 370 ELF.  Somewhat experimental.
 390
 391 * Support for numbers with suffixes.
 392
 393 * Added support for breaking to the end of repeat loops.
 394
 395 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 396
 397 * New .elseif pseudo-op added.
 398
 399 * New --fatal-warnings option.
 400
 401 * picoJava architecture support added.
 402
 403 * Motorola MCore 210 processor support added.
 404
 405 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 406   assembly programs with intel syntax.
 407
 408 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 409
 410 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 411
 412 * Full 16-bit mode support for i386.
 413
 414 * Greatly improved instruction operand checking for i386.  This change will
 415   produce errors or warnings on incorrect assembly code that previous versions
 416   of gas accepted.  If you get unexpected messages from code that worked with
 417   older versions of gas, please double check the code before reporting a bug.
 418
 419 * Weak symbol support added for COFF targets.
 420
 421 * Mitsubishi D30V support added.
 422
 423 * Texas Instruments c80 (tms320c80) support added.
 424
 425 * i960 ELF support added.
 426
 427 * ARM ELF support added.
 428
 429 Changes in 2.9:
 430
 431 * Texas Instruments c30 (tms320c30) support added.
 432
 433 * The assembler now optimizes the exception frame information generated by egcs
 434   and gcc 2.8.  The new --traditional-format option disables this optimization.
 435
 436 * Added --gstabs option to generate stabs debugging information.
 437
 438 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 439   listing.
 440
 441 * Added -MD option to print dependencies.
 442
 443 Changes in 2.8:
 444
 445 * BeOS support added.
 446
 447 * MIPS16 support added.
 448
 449 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 450
 451 * Alpha/VMS support added.
 452
 453 * m68k options --base-size-default-16, --base-size-default-32,
 454   --disp-size-default-16, and --disp-size-default-32 added.
 455
 456 * The alignment directives now take an optional third argument, which is the
 457   maximum number of bytes to skip.  If doing the alignment would require
 458   skipping more than the given number of bytes, the alignment is not done at
 459   all.
 460
 461 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 462
 463 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 464   conditionals in listings.
 465
 466 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 467   the symbol is already defined.
 468
 469 Changes in 2.7:
 470
 471 * The PowerPC assembler now allows the use of symbolic register names (r0,
 472   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 473   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 474   added.
 475
 476 * Alpha Linux (ELF) support added.
 477
 478 * PowerPC ELF support added.
 479
 480 * m68k Linux (ELF) support added.
 481
 482 * i960 Hx/Jx support added.
 483
 484 * i386/PowerPC gnu-win32 support added.
 485
 486 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 487   default is to build COFF-only support.  To get a set of tools that generate
 488   ELF (they'll understand both COFF and ELF), you must configure with
 489   target=i386-unknown-sco3.2v5elf.
 490
 491 * m88k-motorola-sysv3* support added.
 492
 493 Changes in 2.6:
 494
 495 * Gas now directly supports macros, without requiring GASP.
 496
 497 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 498   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 499   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 500
 501 * Added --defsym SYM=VALUE option.
 502
 503 * Added -mips4 support to MIPS assembler.
 504
 505 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 506
 507 Changes in 2.4:
 508
 509 * Converted this directory to use an autoconf-generated configure script.
 510
 511 * ARM support, from Richard Earnshaw.
 512
 513 * Updated VMS support, from Pat Rankin, including considerably improved
 514   debugging support.
 515
 516 * Support for the control registers in the 68060.
 517
 518 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 519   provide for possible future gcc changes, for targets where gas provides some
 520   features not available in the native assembler.  If the native assembler is
 521   used, it should become obvious pretty quickly what the problem is.
 522
 523 * Usage message is available with "--help".
 524
 525 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 526   also, but didn't get into the NEWS file.)
 527
 528 * Weak symbol support for a.out.
 529
 530 * A bug in the listing code which could cause an infinite loop has been fixed.
 531   Bugs in listings when generating a COFF object file have also been fixed.
 532
 533 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 534   Paul Kranenburg.
 535
 536 * Improved Alpha support.  Immediate constants can have a much larger range
 537   now. Support for the 21164 has been contributed by Digital.
 538
 539 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 540
 541 Changes in 2.3:
 542
 543 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 544
 545 * RS/6000 and PowerPC support by Ian Taylor.
 546
 547 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 548   based on mail received from various people.  The `-h#' option should work
 549   again too.
 550
 551 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 552   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 553   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 554   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 555   in the "dist" directory.
 556
 557 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 558   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 559   currently required for BSD 4.3 builds.)
 560
 561 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 562   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 563   the alpha-a.out support is pretty badly mangled, and much of it removed;
 564   making it work will require rewriting it as BFD support for the format anyways.
 565
 566 * Irix 5 support.
 567
 568 * The test suites have been fixed up a bit, so that they should work with a
 569   couple different versions of expect and dejagnu.
 570
 571 * Symbols' values are now handled internally as expressions, permitting more
 572   flexibility in evaluating them in some cases.  Some details of relocation
 573   handling have also changed, and simple constant pool management has been
 574   added, to make the Alpha port easier.
 575
 576 * New option "--statistics" for printing out program run times.  This is
 577   intended to be used with the gcc "-Q" option, which prints out times spent in
 578   various phases of compilation.  (You should be able to get all of them
 579   printed out with "gcc -Q -Wa,--statistics", I think.)
 580
 581 Changes in 2.2:
 582
 583 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 584
 585 * Configurations that are still in development (and therefore are convenient to
 586   have listed in configure.in) still get rejected without a minor change to
 587   gas/Makefile.in, so people not doing development work shouldn't get the
 588   impression that support for such configurations is actually believed to be
 589   reliable.
 590
 591 * The program name (usually "as") is printed when a fatal error message is
 592   displayed.  This should prevent some confusion about the source of occasional
 593   messages about "internal errors".
 594
 595 * ELF support is falling into place.  Support for the 386 should be working.
 596   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 597
 598 * Symbol values are maintained as expressions instead of being immediately
 599   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 600   more complex calculations involving symbols whose values are not alreadey
 601   known.
 602
 603 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 604   If any stabs directives are seen in the source, GAS will create two new
 605   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 606   section is nearly identical to the a.out symbol format, and .stabstr is
 607   its string table.  For this to be useful, you must have configured GCC
 608   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 609   that can use the stab sections (4.11 or later).
 610
 611 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 612   support is in progress.
 613
 614 Changes in 2.1:
 615
 616 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 617   incorporated, but not well tested yet.
 618
 619 * Altered the opcode table split for m68k; it should require less VM to compile
 620   with gcc now.
 621
 622 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 623   suggested by Ronald Cole.
 624
 625 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 626   includes improved ELF support, which I've started adapting for SPARC Solaris
 627   2.x.  Integration isn't completely, so it probably won't work.
 628
 629 * HP9000/300 support, donated by HP, has been merged in.
 630
 631 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 632
 633 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 634
 635 * Test suite framework is starting to become reasonable.
 636
 637 Changes in 2.0:
 638
 639 * Mostly bug fixes.
 640
 641 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 642
 643 Changes in 1.94:
 644
 645 * BFD merge is partly done.  Adventurous souls may try giving configure the
 646   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 647   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 648   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 649   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 650   fully merged yet.)
 651
 652 * The 68K opcode table has been split in half.  It should now compile under gcc
 653   without consuming ridiculous amounts of memory.
 654
 655 * A couple data structures have been reduced in size.  This should result in
 656   saving a little bit of space at runtime.
 657
 658 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 659   code provided ROSE format support, which I haven't merged in yet.  (I can
 660   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 661   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 662   coming.
 663
 664 * Support for the Hitachi H8/500 has been added.
 665
 666 * VMS host and target support should be working now, thanks chiefly to Eric
 667   Youngdale.
 668
 669 Changes in 1.93.01:
 670
 671 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 672
 673 * For i386, .align is now power-of-two; was number-of-bytes.
 674
 675 * For m68k, "%" is now accepted before register names.  For COFF format, which
 676   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 677   can be distinguished from the register.
 678
 679 * Last public release was 1.38.  Lots of configuration changes since then, lots
 680   of new CPUs and formats, lots of bugs fixed.
