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

  29 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  30   assembler support for Argonaut RISC architectures.
  31
  32 * Symbol and label names can now be enclosed in double quotes (") which allows
  33   them to contain characters that are not part of valid symbol names in high
  34   level languages.
  35
  36 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  37   previous spelling, -march=armv6zk, is still accepted.
  38
  39 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  40   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  41   extensions has also been added to the Aarch64 port.

  69   generation of DWARF .debug_line sections.
  70
  71 * Add support for Altera Nios II.
  72
  73 * Add support for the Imagination Technologies Meta processor.
  74
  75 * Add support for the v850e3v5.
  76
  77 * Remove assembler support for MIPS ECOFF targets.
  78
  79 Changes in 2.23:

 105
 106 * Add support for the TMS320C6000 (TI C6X) processor family.
 107
 108 * GAS now understands an extended syntax in the .section directive flags
 109   for COFF targets that allows the section's alignment to be specified.  This
 110   feature has also been backported to the 2.20 release series, starting with
 111   2.20.1.
 112
 113 * Add support for the Renesas RX processor.
 114
 115 * New command line option, --compress-debug-sections, which requests
 116   compression of DWARF debug information sections in the relocatable output
 117   file.  Compressed debug sections are supported by readelf, objdump, and
 118   gold, but not currently by Gnu ld.
 119
 120 Changes in 2.20:
 121
 122 * Added support for v850e2 and v850e2v3.
 123
 124 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 125   pseudo op.  It marks the symbol as being globally unique in the entire
 126   process.
 127
 128 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 129   in binary rather than text.
 130
 131 * Add support for common symbol alignment to PE formats.
 132
 133 * Add support for the new discriminator column in the DWARF line table,
 134   with a discriminator operand for the .loc directive.
 135
 136 * Add support for Sunplus score architecture.
 137
 138 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 139   indicate that if the symbol is the target of a relocation, its value should
 140   not be use.  Instead the function should be invoked and its result used as
 141   the value.
 142
 143 * Add support for Lattice Mico32 (lm32) architecture.
 144
 145 * Add support for Xilinx MicroBlaze architecture.
 146
 147 Changes in 2.19:
 148
 149 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 150   tables without runtime relocation.
 151
 152 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 153   adds compatibility with H'00 style hex constants.
 154
 155 * New command line option, -msse-check=[none|error|warning], for x86
 156   targets.
 157
 158 * New sub-option added to the assembler's -a command line switch to
 159   generate a listing output.  The 'g' sub-option will insert into the listing
 160   various information about the assembly, such as assembler version, the
 161   command line options used, and a time stamp.
 162
 163 * New command line option -msse2avx for x86 target to encode SSE
 164   instructions with VEX prefix.
 165
 166 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 167
 168 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 169   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 170   -mnaked-reg and -mold-gcc, for x86 targets.
 171
 172 * Support for generating wide character strings has been added via the new
 173   pseudo ops: .string16, .string32 and .string64.
 174
 175 * Support for SSE5 has been added to the i386 port.
 176
 177 Changes in 2.18:
 178
 179 * The GAS sources are now released under the GPLv3.
 180
 181 * Support for the National Semiconductor CR16 target has been added.
 182
 183 * Added gas .reloc pseudo.  This is a low-level interface for creating
 184   relocations.
 185
 186 * Add support for x86_64 PE+ target.
 187
 188 * Add support for Score target.
 189
 190 Changes in 2.17:
 191
 192 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 193
 194 * Support for ms2 architecture has been added.
 195
 196 * Support for the Z80 processor family has been added.
 197
 198 * Add support for the "@<file>" syntax to the command line, so that extra
 199   switches can be read from <file>.
 200
 201 * The SH target supports a new command line switch --enable-reg-prefix which,
 202   if enabled, will allow register names to be optionally prefixed with a $
 203   character.  This allows register names to be distinguished from label names.
 204
 205 * Macros with a variable number of arguments are now supported. See the
 206   documentation for how this works.
 207
 208 * Added --reduce-memory-overheads switch to reduce the size of the hash
 209   tables used, at the expense of longer assembly times, and
 210   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 211
 212 * Macro names and macro parameter names can now be any identifier that would
 213   also be legal as a symbol elsewhere. For macro parameter names, this is
 214   known to cause problems in certain sources when the respective target uses
 215   characters inconsistently, and thus macro parameter references may no longer
 216   be recognized as such (see the documentation for details).
 217
 218 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 219   for the VAX target in order to be more compatible with the VAX MACRO
 220   assembler.
 221
 222 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 223
 224 Changes in 2.16:
 225
 226 * Redefinition of macros now results in an error.
 227
 228 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 229
 230 * New command line option -munwind-check=[warning|error] for IA64
 231   targets.
 232
 233 * The IA64 port now uses automatic dependency violation removal as its default
 234   mode.
 235
 236 * Port to MAXQ processor contributed by HCL Tech.
 237
 238 * Added support for generating unwind tables for ARM ELF targets.
 239
 240 * Add a -g command line option to generate debug information in the target's
 241   preferred debug format.
 242
 243 * Support for the crx-elf target added.
 244
 245 * Support for the sh-symbianelf target added.
 246
 247 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 248   on pe[i]-i386; required for this target's DWARF 2 support.
 249
 250 * Support for Motorola MCF521x/5249/547x/548x added.
 251
 252 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 253   instrucitons.
 254
 255 * New command line option -mno-shared for MIPS ELF targets.
 256
 257 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 258   added to enter (and leave) alternate macro syntax mode.
 259
 260 Changes in 2.15:
 261
 262 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 263   deprecated and will be removed in a future release.
 264
 265 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 266
 267 * Added support for ARM V6.
 268
 269 * Added support for sh4a and variants.
 270
 271 * Support for Renesas M32R2 added.
 272
 273 * Limited support for Mapping Symbols as specified in the ARM ELF
 274   specification has been added to the arm assembler.
 275
 276 * On ARM architectures, added a new gas directive ".unreq" that undoes
 277   definitions created by ".req".
 278
 279 * Support for Motorola ColdFire MCF528x added.
 280
 281 * Added --gstabs+ switch to enable the generation of STABS debug format
 282   information with GNU extensions.
 283
 284 * Added support for MIPS64 Release 2.
 285
 286 * Added support for v850e1.
 287
 288 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 289   multiple nop instructions used for alignment within code sections
 290   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 291   switch disables the optimization.
 292
 293 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 294   existing -non_shared option.
 295
 296 Changes in 2.14:
 297
 298 * Added support for MIPS32 Release 2.
 299
 300 * Added support for Xtensa architecture.
 301
 302 * Support for Intel's iWMMXt processor (an ARM variant) added.
 303
 304 * An assembler test generator has been contributed and an example file that
 305   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 306
 307 * Support for SH2E added.
 308
 309 * GASP has now been removed.
 310
 311 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 312   DSP's contributed by Michael Hayes and Svein E. Seldal.
 313
 314 * Support for the Ubicom IP2xxx microcontroller added.
 315
 316 Changes in 2.13:
 317
 318 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 319   and FR500 included.
 320
 321 * Support for DLX processor added.
 322
 323 * GASP has now been deprecated and will be removed in a future release.  Use
 324   the macro facilities in GAS instead.
 325
 326 * GASP now correctly parses floating point numbers. Unless the base is
 327   explicitly specified, they are interpreted as decimal numbers regardless of
 328   the currently specified base.
 329
 330 Changes in 2.12:
 331
 332 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 333
 334 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 335
 336 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 337   specifying the target instruction set.  The old method of specifying the
 338   target processor has been deprecated, but is still accepted for
 339   compatibility.
 340
 341 * Support for the VFP floating-point instruction set has been added to
 342   the ARM assembler.
 343
 344 * New psuedo op: .incbin to include a set of binary data at a given point
 345   in the assembly.  Contributed by Anders Norlander.
 346
 347 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 348   but still works for compatability.
 349
 350 * The MIPS assembler no longer issues a warning by default when it
 351   generates a nop instruction from a macro. The new command line option
 352   -n will turn on the warning.
 353
 354 Changes in 2.11:
 355
 356 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 357
 358 * x86 gas now supports the full Pentium4 instruction set.
 359
 360 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 361
 362 * Support for Motorola 68HC11 and 68HC12.
 363
 364 * Support for Texas Instruments TMS320C54x (tic54x).
 365
 366 * Support for IA-64.
 367
 368 * Support for i860, by Jason Eckhardt.
 369
 370 * Support for CRIS (Axis Communications ETRAX series).
 371
 372 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 373
 374 * x86 gas -q command line option quietens warnings about register size changes
 375   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 376   translating various deprecated floating point instructions.
 377
 378 Changes in 2.10:
 379
 380 * Support for the ARM msr instruction was changed to only allow an immediate
 381   operand when altering the flags field.
 382
 383 * Support for ATMEL AVR.
 384
 385 * Support for IBM 370 ELF.  Somewhat experimental.
 386
 387 * Support for numbers with suffixes.
 388
 389 * Added support for breaking to the end of repeat loops.
 390
 391 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 392
 393 * New .elseif pseudo-op added.
 394
 395 * New --fatal-warnings option.
 396
 397 * picoJava architecture support added.
 398
 399 * Motorola MCore 210 processor support added.
 400
 401 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 402   assembly programs with intel syntax.
 403
 404 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 405
 406 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 407
 408 * Full 16-bit mode support for i386.
 409
 410 * Greatly improved instruction operand checking for i386.  This change will
 411   produce errors or warnings on incorrect assembly code that previous versions
 412   of gas accepted.  If you get unexpected messages from code that worked with
 413   older versions of gas, please double check the code before reporting a bug.
 414
 415 * Weak symbol support added for COFF targets.
 416
 417 * Mitsubishi D30V support added.
 418
 419 * Texas Instruments c80 (tms320c80) support added.
 420
 421 * i960 ELF support added.
 422
 423 * ARM ELF support added.
 424
 425 Changes in 2.9:
 426
 427 * Texas Instruments c30 (tms320c30) support added.
 428
 429 * The assembler now optimizes the exception frame information generated by egcs
 430   and gcc 2.8.  The new --traditional-format option disables this optimization.
 431
 432 * Added --gstabs option to generate stabs debugging information.
 433
 434 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 435   listing.
 436
 437 * Added -MD option to print dependencies.
 438
 439 Changes in 2.8:
 440
 441 * BeOS support added.
 442
 443 * MIPS16 support added.
 444
 445 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 446
 447 * Alpha/VMS support added.
 448
 449 * m68k options --base-size-default-16, --base-size-default-32,
 450   --disp-size-default-16, and --disp-size-default-32 added.
 451
 452 * The alignment directives now take an optional third argument, which is the
 453   maximum number of bytes to skip.  If doing the alignment would require
 454   skipping more than the given number of bytes, the alignment is not done at
 455   all.
 456
 457 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 458
 459 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 460   conditionals in listings.
 461
 462 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 463   the symbol is already defined.
 464
 465 Changes in 2.7:
 466
 467 * The PowerPC assembler now allows the use of symbolic register names (r0,
 468   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 469   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 470   added.
 471
 472 * Alpha Linux (ELF) support added.
 473
 474 * PowerPC ELF support added.
 475
 476 * m68k Linux (ELF) support added.
 477
 478 * i960 Hx/Jx support added.
 479
 480 * i386/PowerPC gnu-win32 support added.
 481
 482 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 483   default is to build COFF-only support.  To get a set of tools that generate
 484   ELF (they'll understand both COFF and ELF), you must configure with
 485   target=i386-unknown-sco3.2v5elf.
 486
 487 * m88k-motorola-sysv3* support added.
 488
 489 Changes in 2.6:
 490
 491 * Gas now directly supports macros, without requiring GASP.
 492
 493 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 494   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 495   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 496
 497 * Added --defsym SYM=VALUE option.
 498
 499 * Added -mips4 support to MIPS assembler.
 500
 501 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 502
 503 Changes in 2.4:
 504
 505 * Converted this directory to use an autoconf-generated configure script.
 506
 507 * ARM support, from Richard Earnshaw.
 508
 509 * Updated VMS support, from Pat Rankin, including considerably improved
 510   debugging support.
 511
 512 * Support for the control registers in the 68060.
 513
 514 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 515   provide for possible future gcc changes, for targets where gas provides some
 516   features not available in the native assembler.  If the native assembler is
 517   used, it should become obvious pretty quickly what the problem is.
 518
 519 * Usage message is available with "--help".
 520
 521 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 522   also, but didn't get into the NEWS file.)
 523
 524 * Weak symbol support for a.out.
 525
 526 * A bug in the listing code which could cause an infinite loop has been fixed.
 527   Bugs in listings when generating a COFF object file have also been fixed.
 528
 529 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 530   Paul Kranenburg.
 531
 532 * Improved Alpha support.  Immediate constants can have a much larger range
 533   now. Support for the 21164 has been contributed by Digital.
 534
 535 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 536
 537 Changes in 2.3:
 538
 539 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 540
 541 * RS/6000 and PowerPC support by Ian Taylor.
 542
 543 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 544   based on mail received from various people.  The `-h#' option should work
 545   again too.
 546
 547 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 548   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 549   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 550   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 551   in the "dist" directory.
 552
 553 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 554   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 555   currently required for BSD 4.3 builds.)
 556
 557 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 558   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 559   the alpha-a.out support is pretty badly mangled, and much of it removed;
 560   making it work will require rewriting it as BFD support for the format anyways.
 561
 562 * Irix 5 support.
 563
 564 * The test suites have been fixed up a bit, so that they should work with a
 565   couple different versions of expect and dejagnu.
 566
 567 * Symbols' values are now handled internally as expressions, permitting more
 568   flexibility in evaluating them in some cases.  Some details of relocation
 569   handling have also changed, and simple constant pool management has been
 570   added, to make the Alpha port easier.
 571
 572 * New option "--statistics" for printing out program run times.  This is
 573   intended to be used with the gcc "-Q" option, which prints out times spent in
 574   various phases of compilation.  (You should be able to get all of them
 575   printed out with "gcc -Q -Wa,--statistics", I think.)
 576
 577 Changes in 2.2:
 578
 579 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 580
 581 * Configurations that are still in development (and therefore are convenient to
 582   have listed in configure.in) still get rejected without a minor change to
 583   gas/Makefile.in, so people not doing development work shouldn't get the
 584   impression that support for such configurations is actually believed to be
 585   reliable.
 586
 587 * The program name (usually "as") is printed when a fatal error message is
 588   displayed.  This should prevent some confusion about the source of occasional
 589   messages about "internal errors".
 590
 591 * ELF support is falling into place.  Support for the 386 should be working.
 592   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 593
 594 * Symbol values are maintained as expressions instead of being immediately
 595   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 596   more complex calculations involving symbols whose values are not alreadey
 597   known.
 598
 599 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 600   If any stabs directives are seen in the source, GAS will create two new
 601   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 602   section is nearly identical to the a.out symbol format, and .stabstr is
 603   its string table.  For this to be useful, you must have configured GCC
 604   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 605   that can use the stab sections (4.11 or later).
 606
 607 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 608   support is in progress.
 609
 610 Changes in 2.1:
 611
 612 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 613   incorporated, but not well tested yet.
 614
 615 * Altered the opcode table split for m68k; it should require less VM to compile
 616   with gcc now.
 617
 618 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 619   suggested by Ronald Cole.
 620
 621 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 622   includes improved ELF support, which I've started adapting for SPARC Solaris
 623   2.x.  Integration isn't completely, so it probably won't work.
 624
 625 * HP9000/300 support, donated by HP, has been merged in.
 626
 627 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 628
 629 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 630
 631 * Test suite framework is starting to become reasonable.
 632
 633 Changes in 2.0:
 634
 635 * Mostly bug fixes.
 636
 637 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 638
 639 Changes in 1.94:
 640
 641 * BFD merge is partly done.  Adventurous souls may try giving configure the
 642   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 643   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 644   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 645   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 646   fully merged yet.)
 647
 648 * The 68K opcode table has been split in half.  It should now compile under gcc
 649   without consuming ridiculous amounts of memory.
 650
 651 * A couple data structures have been reduced in size.  This should result in
 652   saving a little bit of space at runtime.
 653
 654 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 655   code provided ROSE format support, which I haven't merged in yet.  (I can
 656   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 657   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 658   coming.
 659
 660 * Support for the Hitachi H8/500 has been added.
 661
 662 * VMS host and target support should be working now, thanks chiefly to Eric
 663   Youngdale.
 664
 665 Changes in 1.93.01:
 666
 667 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 668
 669 * For i386, .align is now power-of-two; was number-of-bytes.
 670
 671 * For m68k, "%" is now accepted before register names.  For COFF format, which
 672   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 673   can be distinguished from the register.
 674
 675 * Last public release was 1.38.  Lots of configuration changes since then, lots
 676   of new CPUs and formats, lots of bugs fixed.
