   3   sections up to their alignment boundary.
   4
   5 * Support for the ARMv8-M architecture has been added to the ARM port.  Support
   6   for the ARMv8-M Security and DSP Extensions has also been added to the ARM
   7   port.
   8
   9 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  10   .extCoreRegister pseudo-ops that allow an user to define custom
  11   instructions, conditional codes, auxiliary and core registers.
  12
  13 * Add a configure option --enable-elf-stt-common to decide whether ELF
  14   assembler should generate common symbols with the STT_COMMON type by
  15   default.  Default to no.
  16
  17 * New command line option --elf-stt-common= for ELF targets to control
  18   whether to generate common symbols with the STT_COMMON type.
  19
  20 * Add ability to set section flags and types via numeric values for ELF
  21   based targets.
  22
  23 * Add a configure option --enable-x86-relax-relocations to decide whether
  24   x86 assembler should generate relax relocations by default.  Default to
  25   yes, except for x86 Solaris targets older than Solaris 12.
  26
  27 * New command line option -mrelax-relocations= for x86 target to control
  28   whether to generate relax relocations.
  29
  30 * New command line option -mfence-as-lock-add=yes for x86 target to encode
  31   lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
  32

  44   them to contain characters that are not part of valid symbol names in high
  45   level languages.
  46
  47 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  48   previous spelling, -march=armv6zk, is still accepted.
  49
  50 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  51   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  52   extensions has also been added to the Aarch64 port.

  80   generation of DWARF .debug_line sections.
  81
  82 * Add support for Altera Nios II.
  83
  84 * Add support for the Imagination Technologies Meta processor.
  85
  86 * Add support for the v850e3v5.
  87
  88 * Remove assembler support for MIPS ECOFF targets.
  89

 116
 117 * Add support for the TMS320C6000 (TI C6X) processor family.
 118
 119 * GAS now understands an extended syntax in the .section directive flags
 120   for COFF targets that allows the section's alignment to be specified.  This
 121   feature has also been backported to the 2.20 release series, starting with
 122   2.20.1.
 123
 124 * Add support for the Renesas RX processor.
 125
 126 * New command line option, --compress-debug-sections, which requests
 127   compression of DWARF debug information sections in the relocatable output
 128   file.  Compressed debug sections are supported by readelf, objdump, and
 129   gold, but not currently by Gnu ld.
 130
 131 Changes in 2.20:
 132
 133 * Added support for v850e2 and v850e2v3.
 134
 135 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 136   pseudo op.  It marks the symbol as being globally unique in the entire
 137   process.
 138
 139 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 140   in binary rather than text.
 141
 142 * Add support for common symbol alignment to PE formats.
 143
 144 * Add support for the new discriminator column in the DWARF line table,
 145   with a discriminator operand for the .loc directive.
 146
 147 * Add support for Sunplus score architecture.
 148
 149 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 150   indicate that if the symbol is the target of a relocation, its value should
 151   not be use.  Instead the function should be invoked and its result used as
 152   the value.
 153
 154 * Add support for Lattice Mico32 (lm32) architecture.
 155
 156 * Add support for Xilinx MicroBlaze architecture.
 157
 158 Changes in 2.19:
 159
 160 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 161   tables without runtime relocation.
 162
 163 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 164   adds compatibility with H'00 style hex constants.
 165
 166 * New command line option, -msse-check=[none|error|warning], for x86
 167   targets.
 168
 169 * New sub-option added to the assembler's -a command line switch to
 170   generate a listing output.  The 'g' sub-option will insert into the listing
 171   various information about the assembly, such as assembler version, the
 172   command line options used, and a time stamp.
 173
 174 * New command line option -msse2avx for x86 target to encode SSE
 175   instructions with VEX prefix.
 176
 177 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 178
 179 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 180   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 181   -mnaked-reg and -mold-gcc, for x86 targets.
 182
 183 * Support for generating wide character strings has been added via the new
 184   pseudo ops: .string16, .string32 and .string64.
 185
 186 * Support for SSE5 has been added to the i386 port.
 187
 188 Changes in 2.18:
 189
 190 * The GAS sources are now released under the GPLv3.
 191
 192 * Support for the National Semiconductor CR16 target has been added.
 193
 194 * Added gas .reloc pseudo.  This is a low-level interface for creating
 195   relocations.
 196
 197 * Add support for x86_64 PE+ target.
 198
 199 * Add support for Score target.
 200
 201 Changes in 2.17:
 202
 203 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 204
 205 * Support for ms2 architecture has been added.
 206
 207 * Support for the Z80 processor family has been added.
 208
 209 * Add support for the "@<file>" syntax to the command line, so that extra
 210   switches can be read from <file>.
 211
 212 * The SH target supports a new command line switch --enable-reg-prefix which,
 213   if enabled, will allow register names to be optionally prefixed with a $
 214   character.  This allows register names to be distinguished from label names.
 215
 216 * Macros with a variable number of arguments are now supported. See the
 217   documentation for how this works.
 218
 219 * Added --reduce-memory-overheads switch to reduce the size of the hash
 220   tables used, at the expense of longer assembly times, and
 221   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 222
 223 * Macro names and macro parameter names can now be any identifier that would
 224   also be legal as a symbol elsewhere. For macro parameter names, this is
 225   known to cause problems in certain sources when the respective target uses
 226   characters inconsistently, and thus macro parameter references may no longer
 227   be recognized as such (see the documentation for details).
 228
 229 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 230   for the VAX target in order to be more compatible with the VAX MACRO
 231   assembler.
 232
 233 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 234
 235 Changes in 2.16:
 236
 237 * Redefinition of macros now results in an error.
 238
 239 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 240
 241 * New command line option -munwind-check=[warning|error] for IA64
 242   targets.
 243
 244 * The IA64 port now uses automatic dependency violation removal as its default
 245   mode.
 246
 247 * Port to MAXQ processor contributed by HCL Tech.
 248
 249 * Added support for generating unwind tables for ARM ELF targets.
 250
 251 * Add a -g command line option to generate debug information in the target's
 252   preferred debug format.
 253
 254 * Support for the crx-elf target added.
 255
 256 * Support for the sh-symbianelf target added.
 257
 258 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 259   on pe[i]-i386; required for this target's DWARF 2 support.
 260
 261 * Support for Motorola MCF521x/5249/547x/548x added.
 262
 263 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 264   instrucitons.
 265
 266 * New command line option -mno-shared for MIPS ELF targets.
 267
 268 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 269   added to enter (and leave) alternate macro syntax mode.
 270
 271 Changes in 2.15:
 272
 273 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 274   deprecated and will be removed in a future release.
 275
 276 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 277
 278 * Added support for ARM V6.
 279
 280 * Added support for sh4a and variants.
 281
 282 * Support for Renesas M32R2 added.
 283
 284 * Limited support for Mapping Symbols as specified in the ARM ELF
 285   specification has been added to the arm assembler.
 286
 287 * On ARM architectures, added a new gas directive ".unreq" that undoes
 288   definitions created by ".req".
 289
 290 * Support for Motorola ColdFire MCF528x added.
 291
 292 * Added --gstabs+ switch to enable the generation of STABS debug format
 293   information with GNU extensions.
 294
 295 * Added support for MIPS64 Release 2.
 296
 297 * Added support for v850e1.
 298
 299 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 300   multiple nop instructions used for alignment within code sections
 301   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 302   switch disables the optimization.
 303
 304 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 305   existing -non_shared option.
 306
 307 Changes in 2.14:
 308
 309 * Added support for MIPS32 Release 2.
 310
 311 * Added support for Xtensa architecture.
 312
 313 * Support for Intel's iWMMXt processor (an ARM variant) added.
 314
 315 * An assembler test generator has been contributed and an example file that
 316   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 317
 318 * Support for SH2E added.
 319
 320 * GASP has now been removed.
 321
 322 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 323   DSP's contributed by Michael Hayes and Svein E. Seldal.
 324
 325 * Support for the Ubicom IP2xxx microcontroller added.
 326
 327 Changes in 2.13:
 328
 329 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 330   and FR500 included.
 331
 332 * Support for DLX processor added.
 333
 334 * GASP has now been deprecated and will be removed in a future release.  Use
 335   the macro facilities in GAS instead.
 336
 337 * GASP now correctly parses floating point numbers. Unless the base is
 338   explicitly specified, they are interpreted as decimal numbers regardless of
 339   the currently specified base.
 340
 341 Changes in 2.12:
 342
 343 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 344
 345 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 346
 347 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 348   specifying the target instruction set.  The old method of specifying the
 349   target processor has been deprecated, but is still accepted for
 350   compatibility.
 351
 352 * Support for the VFP floating-point instruction set has been added to
 353   the ARM assembler.
 354
 355 * New psuedo op: .incbin to include a set of binary data at a given point
 356   in the assembly.  Contributed by Anders Norlander.
 357
 358 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 359   but still works for compatability.
 360
 361 * The MIPS assembler no longer issues a warning by default when it
 362   generates a nop instruction from a macro. The new command line option
 363   -n will turn on the warning.
 364
 365 Changes in 2.11:
 366
 367 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 368
 369 * x86 gas now supports the full Pentium4 instruction set.
 370
 371 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 372
 373 * Support for Motorola 68HC11 and 68HC12.
 374
 375 * Support for Texas Instruments TMS320C54x (tic54x).
 376
 377 * Support for IA-64.
 378
 379 * Support for i860, by Jason Eckhardt.
 380
 381 * Support for CRIS (Axis Communications ETRAX series).
 382
 383 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 384
 385 * x86 gas -q command line option quietens warnings about register size changes
 386   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 387   translating various deprecated floating point instructions.
 388
 389 Changes in 2.10:
 390
 391 * Support for the ARM msr instruction was changed to only allow an immediate
 392   operand when altering the flags field.
 393
 394 * Support for ATMEL AVR.
 395
 396 * Support for IBM 370 ELF.  Somewhat experimental.
 397
 398 * Support for numbers with suffixes.
 399
 400 * Added support for breaking to the end of repeat loops.
 401
 402 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 403
 404 * New .elseif pseudo-op added.
 405
 406 * New --fatal-warnings option.
 407
 408 * picoJava architecture support added.
 409
 410 * Motorola MCore 210 processor support added.
 411
 412 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 413   assembly programs with intel syntax.
 414
 415 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 416
 417 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 418
 419 * Full 16-bit mode support for i386.
 420
 421 * Greatly improved instruction operand checking for i386.  This change will
 422   produce errors or warnings on incorrect assembly code that previous versions
 423   of gas accepted.  If you get unexpected messages from code that worked with
 424   older versions of gas, please double check the code before reporting a bug.
 425
 426 * Weak symbol support added for COFF targets.
 427
 428 * Mitsubishi D30V support added.
 429
 430 * Texas Instruments c80 (tms320c80) support added.
 431
 432 * i960 ELF support added.
 433
 434 * ARM ELF support added.
 435
 436 Changes in 2.9:
 437
 438 * Texas Instruments c30 (tms320c30) support added.
 439
 440 * The assembler now optimizes the exception frame information generated by egcs
 441   and gcc 2.8.  The new --traditional-format option disables this optimization.
 442
 443 * Added --gstabs option to generate stabs debugging information.
 444
 445 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 446   listing.
 447
 448 * Added -MD option to print dependencies.
 449
 450 Changes in 2.8:
 451
 452 * BeOS support added.
 453
 454 * MIPS16 support added.
 455
 456 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 457
 458 * Alpha/VMS support added.
 459
 460 * m68k options --base-size-default-16, --base-size-default-32,
 461   --disp-size-default-16, and --disp-size-default-32 added.
 462
 463 * The alignment directives now take an optional third argument, which is the
 464   maximum number of bytes to skip.  If doing the alignment would require
 465   skipping more than the given number of bytes, the alignment is not done at
 466   all.
 467
 468 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 469
 470 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 471   conditionals in listings.
 472
 473 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 474   the symbol is already defined.
 475
 476 Changes in 2.7:
 477
 478 * The PowerPC assembler now allows the use of symbolic register names (r0,
 479   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 480   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 481   added.
 482
 483 * Alpha Linux (ELF) support added.
 484
 485 * PowerPC ELF support added.
 486
 487 * m68k Linux (ELF) support added.
 488
 489 * i960 Hx/Jx support added.
 490
 491 * i386/PowerPC gnu-win32 support added.
 492
 493 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 494   default is to build COFF-only support.  To get a set of tools that generate
 495   ELF (they'll understand both COFF and ELF), you must configure with
 496   target=i386-unknown-sco3.2v5elf.
 497
 498 * m88k-motorola-sysv3* support added.
 499
 500 Changes in 2.6:
 501
 502 * Gas now directly supports macros, without requiring GASP.
 503
 504 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 505   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 506   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 507
 508 * Added --defsym SYM=VALUE option.
 509
 510 * Added -mips4 support to MIPS assembler.
 511
 512 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 513
 514 Changes in 2.4:
 515
 516 * Converted this directory to use an autoconf-generated configure script.
 517
 518 * ARM support, from Richard Earnshaw.
 519
 520 * Updated VMS support, from Pat Rankin, including considerably improved
 521   debugging support.
 522
 523 * Support for the control registers in the 68060.
 524
 525 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 526   provide for possible future gcc changes, for targets where gas provides some
 527   features not available in the native assembler.  If the native assembler is
 528   used, it should become obvious pretty quickly what the problem is.
 529
 530 * Usage message is available with "--help".
 531
 532 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 533   also, but didn't get into the NEWS file.)
 534
 535 * Weak symbol support for a.out.
 536
 537 * A bug in the listing code which could cause an infinite loop has been fixed.
 538   Bugs in listings when generating a COFF object file have also been fixed.
 539
 540 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 541   Paul Kranenburg.
 542
 543 * Improved Alpha support.  Immediate constants can have a much larger range
 544   now. Support for the 21164 has been contributed by Digital.
 545
 546 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 547
 548 Changes in 2.3:
 549
 550 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 551
 552 * RS/6000 and PowerPC support by Ian Taylor.
 553
 554 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 555   based on mail received from various people.  The `-h#' option should work
 556   again too.
 557
 558 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 559   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 560   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 561   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 562   in the "dist" directory.
 563
 564 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 565   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 566   currently required for BSD 4.3 builds.)
 567
 568 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 569   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 570   the alpha-a.out support is pretty badly mangled, and much of it removed;
 571   making it work will require rewriting it as BFD support for the format anyways.
 572
 573 * Irix 5 support.
 574
 575 * The test suites have been fixed up a bit, so that they should work with a
 576   couple different versions of expect and dejagnu.
 577
 578 * Symbols' values are now handled internally as expressions, permitting more
 579   flexibility in evaluating them in some cases.  Some details of relocation
 580   handling have also changed, and simple constant pool management has been
 581   added, to make the Alpha port easier.
 582
 583 * New option "--statistics" for printing out program run times.  This is
 584   intended to be used with the gcc "-Q" option, which prints out times spent in
 585   various phases of compilation.  (You should be able to get all of them
 586   printed out with "gcc -Q -Wa,--statistics", I think.)
 587
 588 Changes in 2.2:
 589
 590 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 591
 592 * Configurations that are still in development (and therefore are convenient to
 593   have listed in configure.in) still get rejected without a minor change to
 594   gas/Makefile.in, so people not doing development work shouldn't get the
 595   impression that support for such configurations is actually believed to be
 596   reliable.
 597
 598 * The program name (usually "as") is printed when a fatal error message is
 599   displayed.  This should prevent some confusion about the source of occasional
 600   messages about "internal errors".
 601
 602 * ELF support is falling into place.  Support for the 386 should be working.
 603   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 604
 605 * Symbol values are maintained as expressions instead of being immediately
 606   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 607   more complex calculations involving symbols whose values are not alreadey
 608   known.
 609
 610 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 611   If any stabs directives are seen in the source, GAS will create two new
 612   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 613   section is nearly identical to the a.out symbol format, and .stabstr is
 614   its string table.  For this to be useful, you must have configured GCC
 615   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 616   that can use the stab sections (4.11 or later).
 617
 618 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 619   support is in progress.
 620
 621 Changes in 2.1:
 622
 623 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 624   incorporated, but not well tested yet.
 625
 626 * Altered the opcode table split for m68k; it should require less VM to compile
 627   with gcc now.
 628
 629 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 630   suggested by Ronald Cole.
 631
 632 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 633   includes improved ELF support, which I've started adapting for SPARC Solaris
 634   2.x.  Integration isn't completely, so it probably won't work.
 635
 636 * HP9000/300 support, donated by HP, has been merged in.
 637
 638 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 639
 640 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 641
 642 * Test suite framework is starting to become reasonable.
 643
 644 Changes in 2.0:
 645
 646 * Mostly bug fixes.
 647
 648 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 649
 650 Changes in 1.94:
 651
 652 * BFD merge is partly done.  Adventurous souls may try giving configure the
 653   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 654   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 655   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 656   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 657   fully merged yet.)
 658
 659 * The 68K opcode table has been split in half.  It should now compile under gcc
 660   without consuming ridiculous amounts of memory.
 661
 662 * A couple data structures have been reduced in size.  This should result in
 663   saving a little bit of space at runtime.
 664
 665 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 666   code provided ROSE format support, which I haven't merged in yet.  (I can
 667   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 668   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 669   coming.
 670
 671 * Support for the Hitachi H8/500 has been added.
 672
 673 * VMS host and target support should be working now, thanks chiefly to Eric
 674   Youngdale.
 675
 676 Changes in 1.93.01:
 677
 678 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 679
 680 * For i386, .align is now power-of-two; was number-of-bytes.
 681
 682 * For m68k, "%" is now accepted before register names.  For COFF format, which
 683   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 684   can be distinguished from the register.
 685
 686 * Last public release was 1.38.  Lots of configuration changes since then, lots
 687   of new CPUs and formats, lots of bugs fixed.
