   2
   3 * Add support for the RISC-V architecture.
   4
   5 Changes in 2.27:
   6
   7 * Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
   8
   9 * Add --no-pad-sections to stop the assembler from padding the end of output
  10   sections up to their alignment boundary.
  11
  12 * Support for the ARMv8-M architecture has been added to the ARM port.  Support
  13   for the ARMv8-M Security and DSP Extensions has also been added to the ARM
  14   port.
  15
  16 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  17   .extCoreRegister pseudo-ops that allow an user to define custom
  18   instructions, conditional codes, auxiliary and core registers.
  19
  20 * Add a configure option --enable-elf-stt-common to decide whether ELF
  21   assembler should generate common symbols with the STT_COMMON type by
  22   default.  Default to no.
  23
  24 * New command line option --elf-stt-common= for ELF targets to control
  25   whether to generate common symbols with the STT_COMMON type.
  26
  27 * Add ability to set section flags and types via numeric values for ELF
  28   based targets.
  29
  30 * Add a configure option --enable-x86-relax-relocations to decide whether
  31   x86 assembler should generate relax relocations by default.  Default to
  32   yes, except for x86 Solaris targets older than Solaris 12.
  33
  34 * New command line option -mrelax-relocations= for x86 target to control
  35   whether to generate relax relocations.
  36
  37 * New command line option -mfence-as-lock-add=yes for x86 target to encode

  39
  40 * Add assembly-time relaxation option for ARC cpus.
  41
  42 * Add --with-cpu=TYPE configure option for ARC gas.  This allows the default
  43   cpu type to be adjusted at configure time.
  44
  45 Changes in 2.26:
  46
  47 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  48   decide whether DWARF debug sections should be compressed by default.
  49
  50 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  51   assembler support for Argonaut RISC architectures.
  52
  53 * Symbol and label names can now be enclosed in double quotes (") which allows
  54   them to contain characters that are not part of valid symbol names in high
  55   level languages.
  56
  57 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  58   previous spelling, -march=armv6zk, is still accepted.
  59
  60 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  61   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  62   extensions has also been added to the Aarch64 port.

  90   generation of DWARF .debug_line sections.
  91
  92 * Add support for Altera Nios II.
  93
  94 * Add support for the Imagination Technologies Meta processor.

 112
 113 * Add support for the Renesas RL78 architecture.
 114
 115 * Add support for the Adapteva EPIPHANY architecture.
 116

 126
 127 * Add support for the TMS320C6000 (TI C6X) processor family.
 128
 129 * GAS now understands an extended syntax in the .section directive flags
 130   for COFF targets that allows the section's alignment to be specified.  This
 131   feature has also been backported to the 2.20 release series, starting with
 132   2.20.1.
 133
 134 * Add support for the Renesas RX processor.
 135
 136 * New command line option, --compress-debug-sections, which requests
 137   compression of DWARF debug information sections in the relocatable output
 138   file.  Compressed debug sections are supported by readelf, objdump, and
 139   gold, but not currently by Gnu ld.
 140
 141 Changes in 2.20:
 142
 143 * Added support for v850e2 and v850e2v3.
 144
 145 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 146   pseudo op.  It marks the symbol as being globally unique in the entire
 147   process.
 148
 149 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 150   in binary rather than text.
 151
 152 * Add support for common symbol alignment to PE formats.
 153
 154 * Add support for the new discriminator column in the DWARF line table,
 155   with a discriminator operand for the .loc directive.
 156
 157 * Add support for Sunplus score architecture.
 158
 159 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 160   indicate that if the symbol is the target of a relocation, its value should
 161   not be use.  Instead the function should be invoked and its result used as
 162   the value.
 163
 164 * Add support for Lattice Mico32 (lm32) architecture.
 165
 166 * Add support for Xilinx MicroBlaze architecture.
 167
 168 Changes in 2.19:
 169
 170 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 171   tables without runtime relocation.
 172
 173 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 174   adds compatibility with H'00 style hex constants.
 175
 176 * New command line option, -msse-check=[none|error|warning], for x86
 177   targets.
 178
 179 * New sub-option added to the assembler's -a command line switch to
 180   generate a listing output.  The 'g' sub-option will insert into the listing
 181   various information about the assembly, such as assembler version, the
 182   command line options used, and a time stamp.
 183
 184 * New command line option -msse2avx for x86 target to encode SSE
 185   instructions with VEX prefix.
 186
 187 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 188
 189 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 190   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 191   -mnaked-reg and -mold-gcc, for x86 targets.
 192
 193 * Support for generating wide character strings has been added via the new
 194   pseudo ops: .string16, .string32 and .string64.
 195
 196 * Support for SSE5 has been added to the i386 port.
 197
 198 Changes in 2.18:
 199
 200 * The GAS sources are now released under the GPLv3.
 201
 202 * Support for the National Semiconductor CR16 target has been added.
 203
 204 * Added gas .reloc pseudo.  This is a low-level interface for creating
 205   relocations.
 206
 207 * Add support for x86_64 PE+ target.
 208
 209 * Add support for Score target.
 210
 211 Changes in 2.17:
 212
 213 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 214
 215 * Support for ms2 architecture has been added.
 216
 217 * Support for the Z80 processor family has been added.
 218
 219 * Add support for the "@<file>" syntax to the command line, so that extra
 220   switches can be read from <file>.
 221
 222 * The SH target supports a new command line switch --enable-reg-prefix which,
 223   if enabled, will allow register names to be optionally prefixed with a $
 224   character.  This allows register names to be distinguished from label names.
 225
 226 * Macros with a variable number of arguments are now supported. See the
 227   documentation for how this works.
 228
 229 * Added --reduce-memory-overheads switch to reduce the size of the hash
 230   tables used, at the expense of longer assembly times, and
 231   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 232
 233 * Macro names and macro parameter names can now be any identifier that would
 234   also be legal as a symbol elsewhere. For macro parameter names, this is
 235   known to cause problems in certain sources when the respective target uses
 236   characters inconsistently, and thus macro parameter references may no longer
 237   be recognized as such (see the documentation for details).
 238
 239 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 240   for the VAX target in order to be more compatible with the VAX MACRO
 241   assembler.
 242
 243 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 244
 245 Changes in 2.16:
 246
 247 * Redefinition of macros now results in an error.
 248
 249 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 250
 251 * New command line option -munwind-check=[warning|error] for IA64
 252   targets.
 253
 254 * The IA64 port now uses automatic dependency violation removal as its default
 255   mode.
 256
 257 * Port to MAXQ processor contributed by HCL Tech.
 258
 259 * Added support for generating unwind tables for ARM ELF targets.
 260
 261 * Add a -g command line option to generate debug information in the target's
 262   preferred debug format.
 263
 264 * Support for the crx-elf target added.
 265
 266 * Support for the sh-symbianelf target added.
 267
 268 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 269   on pe[i]-i386; required for this target's DWARF 2 support.
 270
 271 * Support for Motorola MCF521x/5249/547x/548x added.
 272
 273 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 274   instrucitons.
 275
 276 * New command line option -mno-shared for MIPS ELF targets.
 277
 278 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 279   added to enter (and leave) alternate macro syntax mode.
 280
 281 Changes in 2.15:
 282
 283 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 284   deprecated and will be removed in a future release.
 285
 286 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 287
 288 * Added support for ARM V6.
 289
 290 * Added support for sh4a and variants.
 291
 292 * Support for Renesas M32R2 added.
 293
 294 * Limited support for Mapping Symbols as specified in the ARM ELF
 295   specification has been added to the arm assembler.
 296
 297 * On ARM architectures, added a new gas directive ".unreq" that undoes
 298   definitions created by ".req".
 299
 300 * Support for Motorola ColdFire MCF528x added.
 301
 302 * Added --gstabs+ switch to enable the generation of STABS debug format
 303   information with GNU extensions.
 304
 305 * Added support for MIPS64 Release 2.
 306
 307 * Added support for v850e1.
 308
 309 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 310   multiple nop instructions used for alignment within code sections
 311   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 312   switch disables the optimization.
 313
 314 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 315   existing -non_shared option.
 316
 317 Changes in 2.14:
 318
 319 * Added support for MIPS32 Release 2.
 320
 321 * Added support for Xtensa architecture.
 322
 323 * Support for Intel's iWMMXt processor (an ARM variant) added.
 324
 325 * An assembler test generator has been contributed and an example file that
 326   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 327
 328 * Support for SH2E added.
 329
 330 * GASP has now been removed.
 331
 332 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 333   DSP's contributed by Michael Hayes and Svein E. Seldal.
 334
 335 * Support for the Ubicom IP2xxx microcontroller added.
 336
 337 Changes in 2.13:
 338
 339 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 340   and FR500 included.
 341
 342 * Support for DLX processor added.
 343
 344 * GASP has now been deprecated and will be removed in a future release.  Use
 345   the macro facilities in GAS instead.
 346
 347 * GASP now correctly parses floating point numbers. Unless the base is
 348   explicitly specified, they are interpreted as decimal numbers regardless of
 349   the currently specified base.
 350
 351 Changes in 2.12:
 352
 353 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 354
 355 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 356
 357 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 358   specifying the target instruction set.  The old method of specifying the
 359   target processor has been deprecated, but is still accepted for
 360   compatibility.
 361
 362 * Support for the VFP floating-point instruction set has been added to
 363   the ARM assembler.
 364
 365 * New psuedo op: .incbin to include a set of binary data at a given point
 366   in the assembly.  Contributed by Anders Norlander.
 367
 368 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 369   but still works for compatability.
 370
 371 * The MIPS assembler no longer issues a warning by default when it
 372   generates a nop instruction from a macro. The new command line option
 373   -n will turn on the warning.
 374
 375 Changes in 2.11:
 376
 377 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 378
 379 * x86 gas now supports the full Pentium4 instruction set.
 380
 381 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 382
 383 * Support for Motorola 68HC11 and 68HC12.
 384
 385 * Support for Texas Instruments TMS320C54x (tic54x).
 386
 387 * Support for IA-64.
 388
 389 * Support for i860, by Jason Eckhardt.
 390
 391 * Support for CRIS (Axis Communications ETRAX series).
 392
 393 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 394
 395 * x86 gas -q command line option quietens warnings about register size changes
 396   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 397   translating various deprecated floating point instructions.
 398
 399 Changes in 2.10:
 400
 401 * Support for the ARM msr instruction was changed to only allow an immediate
 402   operand when altering the flags field.
 403
 404 * Support for ATMEL AVR.
 405
 406 * Support for IBM 370 ELF.  Somewhat experimental.
 407
 408 * Support for numbers with suffixes.
 409
 410 * Added support for breaking to the end of repeat loops.
 411
 412 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 413
 414 * New .elseif pseudo-op added.
 415
 416 * New --fatal-warnings option.
 417
 418 * picoJava architecture support added.
 419
 420 * Motorola MCore 210 processor support added.
 421
 422 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 423   assembly programs with intel syntax.
 424
 425 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 426
 427 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 428
 429 * Full 16-bit mode support for i386.
 430
 431 * Greatly improved instruction operand checking for i386.  This change will
 432   produce errors or warnings on incorrect assembly code that previous versions
 433   of gas accepted.  If you get unexpected messages from code that worked with
 434   older versions of gas, please double check the code before reporting a bug.
 435
 436 * Weak symbol support added for COFF targets.
 437
 438 * Mitsubishi D30V support added.
 439
 440 * Texas Instruments c80 (tms320c80) support added.
 441
 442 * i960 ELF support added.
 443
 444 * ARM ELF support added.
 445
 446 Changes in 2.9:
 447
 448 * Texas Instruments c30 (tms320c30) support added.
 449
 450 * The assembler now optimizes the exception frame information generated by egcs
 451   and gcc 2.8.  The new --traditional-format option disables this optimization.
 452
 453 * Added --gstabs option to generate stabs debugging information.
 454
 455 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 456   listing.
 457
 458 * Added -MD option to print dependencies.
 459
 460 Changes in 2.8:
 461
 462 * BeOS support added.
 463
 464 * MIPS16 support added.
 465
 466 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 467
 468 * Alpha/VMS support added.
 469
 470 * m68k options --base-size-default-16, --base-size-default-32,
 471   --disp-size-default-16, and --disp-size-default-32 added.
 472
 473 * The alignment directives now take an optional third argument, which is the
 474   maximum number of bytes to skip.  If doing the alignment would require
 475   skipping more than the given number of bytes, the alignment is not done at
 476   all.
 477
 478 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 479
 480 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 481   conditionals in listings.
 482
 483 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 484   the symbol is already defined.
 485
 486 Changes in 2.7:
 487
 488 * The PowerPC assembler now allows the use of symbolic register names (r0,
 489   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 490   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 491   added.
 492
 493 * Alpha Linux (ELF) support added.
 494
 495 * PowerPC ELF support added.
 496
 497 * m68k Linux (ELF) support added.
 498
 499 * i960 Hx/Jx support added.
 500
 501 * i386/PowerPC gnu-win32 support added.
 502
 503 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 504   default is to build COFF-only support.  To get a set of tools that generate
 505   ELF (they'll understand both COFF and ELF), you must configure with
 506   target=i386-unknown-sco3.2v5elf.
 507
 508 * m88k-motorola-sysv3* support added.
 509
 510 Changes in 2.6:
 511
 512 * Gas now directly supports macros, without requiring GASP.
 513
 514 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 515   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 516   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 517
 518 * Added --defsym SYM=VALUE option.
 519
 520 * Added -mips4 support to MIPS assembler.
 521
 522 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 523
 524 Changes in 2.4:
 525
 526 * Converted this directory to use an autoconf-generated configure script.
 527
 528 * ARM support, from Richard Earnshaw.
 529
 530 * Updated VMS support, from Pat Rankin, including considerably improved
 531   debugging support.
 532
 533 * Support for the control registers in the 68060.
 534
 535 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 536   provide for possible future gcc changes, for targets where gas provides some
 537   features not available in the native assembler.  If the native assembler is
 538   used, it should become obvious pretty quickly what the problem is.
 539
 540 * Usage message is available with "--help".
 541
 542 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 543   also, but didn't get into the NEWS file.)
 544
 545 * Weak symbol support for a.out.
 546
 547 * A bug in the listing code which could cause an infinite loop has been fixed.
 548   Bugs in listings when generating a COFF object file have also been fixed.
 549
 550 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 551   Paul Kranenburg.
 552
 553 * Improved Alpha support.  Immediate constants can have a much larger range
 554   now. Support for the 21164 has been contributed by Digital.
 555
 556 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 557
 558 Changes in 2.3:
 559
 560 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 561
 562 * RS/6000 and PowerPC support by Ian Taylor.
 563
 564 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 565   based on mail received from various people.  The `-h#' option should work
 566   again too.
 567
 568 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 569   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 570   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 571   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 572   in the "dist" directory.
 573
 574 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 575   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 576   currently required for BSD 4.3 builds.)
 577
 578 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 579   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 580   the alpha-a.out support is pretty badly mangled, and much of it removed;
 581   making it work will require rewriting it as BFD support for the format anyways.
 582
 583 * Irix 5 support.
 584
 585 * The test suites have been fixed up a bit, so that they should work with a
 586   couple different versions of expect and dejagnu.
 587
 588 * Symbols' values are now handled internally as expressions, permitting more
 589   flexibility in evaluating them in some cases.  Some details of relocation
 590   handling have also changed, and simple constant pool management has been
 591   added, to make the Alpha port easier.
 592
 593 * New option "--statistics" for printing out program run times.  This is
 594   intended to be used with the gcc "-Q" option, which prints out times spent in
 595   various phases of compilation.  (You should be able to get all of them
 596   printed out with "gcc -Q -Wa,--statistics", I think.)
 597
 598 Changes in 2.2:
 599
 600 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 601
 602 * Configurations that are still in development (and therefore are convenient to
 603   have listed in configure.in) still get rejected without a minor change to
 604   gas/Makefile.in, so people not doing development work shouldn't get the
 605   impression that support for such configurations is actually believed to be
 606   reliable.
 607
 608 * The program name (usually "as") is printed when a fatal error message is
 609   displayed.  This should prevent some confusion about the source of occasional
 610   messages about "internal errors".
 611
 612 * ELF support is falling into place.  Support for the 386 should be working.
 613   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 614
 615 * Symbol values are maintained as expressions instead of being immediately
 616   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 617   more complex calculations involving symbols whose values are not alreadey
 618   known.
 619
 620 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 621   If any stabs directives are seen in the source, GAS will create two new
 622   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 623   section is nearly identical to the a.out symbol format, and .stabstr is
 624   its string table.  For this to be useful, you must have configured GCC
 625   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 626   that can use the stab sections (4.11 or later).
 627
 628 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 629   support is in progress.
 630
 631 Changes in 2.1:
 632
 633 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 634   incorporated, but not well tested yet.
 635
 636 * Altered the opcode table split for m68k; it should require less VM to compile
 637   with gcc now.
 638
 639 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 640   suggested by Ronald Cole.
 641
 642 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 643   includes improved ELF support, which I've started adapting for SPARC Solaris
 644   2.x.  Integration isn't completely, so it probably won't work.
 645
 646 * HP9000/300 support, donated by HP, has been merged in.
 647
 648 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 649
 650 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 651
 652 * Test suite framework is starting to become reasonable.
 653
 654 Changes in 2.0:
 655
 656 * Mostly bug fixes.
 657
 658 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 659
 660 Changes in 1.94:
 661
 662 * BFD merge is partly done.  Adventurous souls may try giving configure the
 663   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 664   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 665   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 666   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 667   fully merged yet.)
 668
 669 * The 68K opcode table has been split in half.  It should now compile under gcc
 670   without consuming ridiculous amounts of memory.
 671
 672 * A couple data structures have been reduced in size.  This should result in
 673   saving a little bit of space at runtime.
 674
 675 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 676   code provided ROSE format support, which I haven't merged in yet.  (I can
 677   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 678   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 679   coming.
 680
 681 * Support for the Hitachi H8/500 has been added.
 682
 683 * VMS host and target support should be working now, thanks chiefly to Eric
 684   Youngdale.
 685
 686 Changes in 1.93.01:
 687
 688 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 689
 690 * For i386, .align is now power-of-two; was number-of-bytes.
 691
 692 * For m68k, "%" is now accepted before register names.  For COFF format, which
 693   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 694   can be distinguished from the register.
 695
 696 * Last public release was 1.38.  Lots of configuration changes since then, lots
 697   of new CPUs and formats, lots of bugs fixed.
