   3 Changes in 2.26:
   4
   5 * Add a configure option --enable-compressed-debug-sections={all,gas} to
   6   decide whether DWARF debug sections should be compressed by default.
   7
   8 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
   9   assembler support for Argonaut RISC architectures.
  10
  11 * Symbol and label names can now be enclosed in double quotes (") which allows
  12   them to contain characters that are not part of valid symbol names in high
  13   level languages.
  14
  15 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  16   previous spelling, -march=armv6zk, is still accepted.
  17
  18 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  19   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  20   extensions has also been added to the Aarch64 port.
  21
  22 * Support for the ARMv8.1 architecture has been added to the ARM port.  Support
  23   for the individual ARMv8.1 Adv.SIMD and PAN architecture extensions has also
  24   been added to the ARM port.
  25
  26 * Extend --compress-debug-sections option to support
  27   --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
  28   targets.
  29
  30 * --compress-debug-sections is turned on for Linux/x86 by default.
  31
  32 Changes in 2.25:
  33
  34 * Add support for the AVR Tiny microcontrollers.
  35
  36 * Replace support for openrisc and or32 with support for or1k.
  37
  38 * Enhanced the ARM port to accept the assembler output from the CodeComposer
  39   Studio tool.  Support is enabled via the new command line option -mccs.
  40
  41 * Add support for the Andes NDS32.
  42
  43 Changes in 2.24:
  44
  45 * Add support for the Texas Instruments MSP430X processor.
  46
  47 * Add -gdwarf-sections command line option to enable per-code-section
  48   generation of DWARF .debug_line sections.
  49
  50 * Add support for Altera Nios II.
  51
  52 * Add support for the Imagination Technologies Meta processor.
  53
  54 * Add support for the v850e3v5.
  55
  56 * Remove assembler support for MIPS ECOFF targets.
  57
  58 Changes in 2.23:
  59
  60 * Add support for the 64-bit ARM architecture: AArch64.
  61
  62 * Add support for S12X processor.
  63
  64 * Add support for the VLE extension to the PowerPC architecture.
  65
  66 * Add support for the Freescale XGATE architecture.
  67
  68 * Add support for .bundle_align_mode, .bundle_lock, and .bundle_unlock
  69   directives.  These are currently available only for x86 and ARM targets.
  70
  71 * Add support for the Renesas RL78 architecture.
  72
  73 * Add support for the Adapteva EPIPHANY architecture.
  74
  75 * For x86, allow 'rep bsf', 'rep bsr', and 'rep ret' syntax.
  76
  77 Changes in 2.22:
  78
  79 * Add support for the Tilera TILEPro and TILE-Gx architectures.
  80
  81 Changes in 2.21:
  82
  83 * Gas no longer requires doubling of ampersands in macros.
  84
  85 * Add support for the TMS320C6000 (TI C6X) processor family.
  86
  87 * GAS now understands an extended syntax in the .section directive flags
  88   for COFF targets that allows the section's alignment to be specified.  This
  89   feature has also been backported to the 2.20 release series, starting with
  90   2.20.1.
  91
  92 * Add support for the Renesas RX processor.
  93
  94 * New command line option, --compress-debug-sections, which requests
  95   compression of DWARF debug information sections in the relocatable output
  96   file.  Compressed debug sections are supported by readelf, objdump, and
  97   gold, but not currently by Gnu ld.
  98
  99 Changes in 2.20:
 100
 101 * Added support for v850e2 and v850e2v3.
 102
 103 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 104   pseudo op.  It marks the symbol as being globally unique in the entire
 105   process.
 106
 107 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 108   in binary rather than text.
 109
 110 * Add support for common symbol alignment to PE formats.
 111
 112 * Add support for the new discriminator column in the DWARF line table,
 113   with a discriminator operand for the .loc directive.
 114
 115 * Add support for Sunplus score architecture.
 116
 117 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 118   indicate that if the symbol is the target of a relocation, its value should
 119   not be use.  Instead the function should be invoked and its result used as
 120   the value.
 121
 122 * Add support for Lattice Mico32 (lm32) architecture.
 123
 124 * Add support for Xilinx MicroBlaze architecture.
 125
 126 Changes in 2.19:
 127
 128 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 129   tables without runtime relocation.
 130
 131 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 132   adds compatibility with H'00 style hex constants.
 133
 134 * New command line option, -msse-check=[none|error|warning], for x86
 135   targets.
 136
 137 * New sub-option added to the assembler's -a command line switch to
 138   generate a listing output.  The 'g' sub-option will insert into the listing
 139   various information about the assembly, such as assembler version, the
 140   command line options used, and a time stamp.
 141
 142 * New command line option -msse2avx for x86 target to encode SSE
 143   instructions with VEX prefix.
 144
 145 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 146
 147 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 148   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 149   -mnaked-reg and -mold-gcc, for x86 targets.
 150
 151 * Support for generating wide character strings has been added via the new
 152   pseudo ops: .string16, .string32 and .string64.
 153
 154 * Support for SSE5 has been added to the i386 port.
 155
 156 Changes in 2.18:
 157
 158 * The GAS sources are now released under the GPLv3.
 159
 160 * Support for the National Semiconductor CR16 target has been added.
 161
 162 * Added gas .reloc pseudo.  This is a low-level interface for creating
 163   relocations.
 164
 165 * Add support for x86_64 PE+ target.
 166
 167 * Add support for Score target.
 168
 169 Changes in 2.17:
 170
 171 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 172
 173 * Support for ms2 architecture has been added.
 174
 175 * Support for the Z80 processor family has been added.
 176
 177 * Add support for the "@<file>" syntax to the command line, so that extra
 178   switches can be read from <file>.
 179
 180 * The SH target supports a new command line switch --enable-reg-prefix which,
 181   if enabled, will allow register names to be optionally prefixed with a $
 182   character.  This allows register names to be distinguished from label names.
 183
 184 * Macros with a variable number of arguments are now supported. See the
 185   documentation for how this works.
 186
 187 * Added --reduce-memory-overheads switch to reduce the size of the hash
 188   tables used, at the expense of longer assembly times, and
 189   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 190
 191 * Macro names and macro parameter names can now be any identifier that would
 192   also be legal as a symbol elsewhere. For macro parameter names, this is
 193   known to cause problems in certain sources when the respective target uses
 194   characters inconsistently, and thus macro parameter references may no longer
 195   be recognized as such (see the documentation for details).
 196
 197 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 198   for the VAX target in order to be more compatible with the VAX MACRO
 199   assembler.
 200
 201 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 202
 203 Changes in 2.16:
 204
 205 * Redefinition of macros now results in an error.
 206
 207 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 208
 209 * New command line option -munwind-check=[warning|error] for IA64
 210   targets.
 211
 212 * The IA64 port now uses automatic dependency violation removal as its default
 213   mode.
 214
 215 * Port to MAXQ processor contributed by HCL Tech.
 216
 217 * Added support for generating unwind tables for ARM ELF targets.
 218
 219 * Add a -g command line option to generate debug information in the target's
 220   preferred debug format.
 221
 222 * Support for the crx-elf target added.
 223
 224 * Support for the sh-symbianelf target added.
 225
 226 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 227   on pe[i]-i386; required for this target's DWARF 2 support.
 228
 229 * Support for Motorola MCF521x/5249/547x/548x added.
 230
 231 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 232   instrucitons.
 233
 234 * New command line option -mno-shared for MIPS ELF targets.
 235
 236 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 237   added to enter (and leave) alternate macro syntax mode.
 238
 239 Changes in 2.15:
 240
 241 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 242   deprecated and will be removed in a future release.
 243
 244 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 245
 246 * Added support for ARM V6.
 247
 248 * Added support for sh4a and variants.
 249
 250 * Support for Renesas M32R2 added.
 251
 252 * Limited support for Mapping Symbols as specified in the ARM ELF
 253   specification has been added to the arm assembler.
 254
 255 * On ARM architectures, added a new gas directive ".unreq" that undoes
 256   definitions created by ".req".
 257
 258 * Support for Motorola ColdFire MCF528x added.
 259
 260 * Added --gstabs+ switch to enable the generation of STABS debug format
 261   information with GNU extensions.
 262
 263 * Added support for MIPS64 Release 2.
 264
 265 * Added support for v850e1.
 266
 267 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 268   multiple nop instructions used for alignment within code sections
 269   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 270   switch disables the optimization.
 271
 272 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 273   existing -non_shared option.
 274
 275 Changes in 2.14:
 276
 277 * Added support for MIPS32 Release 2.
 278
 279 * Added support for Xtensa architecture.
 280
 281 * Support for Intel's iWMMXt processor (an ARM variant) added.
 282
 283 * An assembler test generator has been contributed and an example file that
 284   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 285
 286 * Support for SH2E added.
 287
 288 * GASP has now been removed.
 289
 290 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 291   DSP's contributed by Michael Hayes and Svein E. Seldal.
 292
 293 * Support for the Ubicom IP2xxx microcontroller added.
 294
 295 Changes in 2.13:
 296
 297 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 298   and FR500 included.
 299
 300 * Support for DLX processor added.
 301
 302 * GASP has now been deprecated and will be removed in a future release.  Use
 303   the macro facilities in GAS instead.
 304
 305 * GASP now correctly parses floating point numbers. Unless the base is
 306   explicitly specified, they are interpreted as decimal numbers regardless of
 307   the currently specified base.
 308
 309 Changes in 2.12:
 310
 311 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 312
 313 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 314
 315 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 316   specifying the target instruction set.  The old method of specifying the
 317   target processor has been deprecated, but is still accepted for
 318   compatibility.
 319
 320 * Support for the VFP floating-point instruction set has been added to
 321   the ARM assembler.
 322
 323 * New psuedo op: .incbin to include a set of binary data at a given point
 324   in the assembly.  Contributed by Anders Norlander.
 325
 326 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 327   but still works for compatability.
 328
 329 * The MIPS assembler no longer issues a warning by default when it
 330   generates a nop instruction from a macro. The new command line option
 331   -n will turn on the warning.
 332
 333 Changes in 2.11:
 334
 335 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 336
 337 * x86 gas now supports the full Pentium4 instruction set.
 338
 339 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 340
 341 * Support for Motorola 68HC11 and 68HC12.
 342
 343 * Support for Texas Instruments TMS320C54x (tic54x).
 344
 345 * Support for IA-64.
 346
 347 * Support for i860, by Jason Eckhardt.
 348
 349 * Support for CRIS (Axis Communications ETRAX series).
 350
 351 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 352
 353 * x86 gas -q command line option quietens warnings about register size changes
 354   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 355   translating various deprecated floating point instructions.
 356
 357 Changes in 2.10:
 358
 359 * Support for the ARM msr instruction was changed to only allow an immediate
 360   operand when altering the flags field.
 361
 362 * Support for ATMEL AVR.
 363
 364 * Support for IBM 370 ELF.  Somewhat experimental.
 365
 366 * Support for numbers with suffixes.
 367
 368 * Added support for breaking to the end of repeat loops.
 369
 370 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 371
 372 * New .elseif pseudo-op added.
 373
 374 * New --fatal-warnings option.
 375
 376 * picoJava architecture support added.
 377
 378 * Motorola MCore 210 processor support added.
 379
 380 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 381   assembly programs with intel syntax.
 382
 383 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 384
 385 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 386
 387 * Full 16-bit mode support for i386.
 388
 389 * Greatly improved instruction operand checking for i386.  This change will
 390   produce errors or warnings on incorrect assembly code that previous versions
 391   of gas accepted.  If you get unexpected messages from code that worked with
 392   older versions of gas, please double check the code before reporting a bug.
 393
 394 * Weak symbol support added for COFF targets.
 395
 396 * Mitsubishi D30V support added.
 397
 398 * Texas Instruments c80 (tms320c80) support added.
 399
 400 * i960 ELF support added.
 401
 402 * ARM ELF support added.
 403
 404 Changes in 2.9:
 405
 406 * Texas Instruments c30 (tms320c30) support added.
 407
 408 * The assembler now optimizes the exception frame information generated by egcs
 409   and gcc 2.8.  The new --traditional-format option disables this optimization.
 410
 411 * Added --gstabs option to generate stabs debugging information.
 412
 413 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 414   listing.
 415
 416 * Added -MD option to print dependencies.
 417
 418 Changes in 2.8:
 419
 420 * BeOS support added.
 421
 422 * MIPS16 support added.
 423
 424 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 425
 426 * Alpha/VMS support added.
 427
 428 * m68k options --base-size-default-16, --base-size-default-32,
 429   --disp-size-default-16, and --disp-size-default-32 added.
 430
 431 * The alignment directives now take an optional third argument, which is the
 432   maximum number of bytes to skip.  If doing the alignment would require
 433   skipping more than the given number of bytes, the alignment is not done at
 434   all.
 435
 436 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 437
 438 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 439   conditionals in listings.
 440
 441 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 442   the symbol is already defined.
 443
 444 Changes in 2.7:
 445
 446 * The PowerPC assembler now allows the use of symbolic register names (r0,
 447   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 448   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 449   added.
 450
 451 * Alpha Linux (ELF) support added.
 452
 453 * PowerPC ELF support added.
 454
 455 * m68k Linux (ELF) support added.
 456
 457 * i960 Hx/Jx support added.
 458
 459 * i386/PowerPC gnu-win32 support added.
 460
 461 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 462   default is to build COFF-only support.  To get a set of tools that generate
 463   ELF (they'll understand both COFF and ELF), you must configure with
 464   target=i386-unknown-sco3.2v5elf.
 465
 466 * m88k-motorola-sysv3* support added.
 467
 468 Changes in 2.6:
 469
 470 * Gas now directly supports macros, without requiring GASP.
 471
 472 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 473   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 474   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 475
 476 * Added --defsym SYM=VALUE option.
 477
 478 * Added -mips4 support to MIPS assembler.
 479
 480 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 481
 482 Changes in 2.4:
 483
 484 * Converted this directory to use an autoconf-generated configure script.
 485
 486 * ARM support, from Richard Earnshaw.
 487
 488 * Updated VMS support, from Pat Rankin, including considerably improved
 489   debugging support.
 490
 491 * Support for the control registers in the 68060.
 492
 493 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 494   provide for possible future gcc changes, for targets where gas provides some
 495   features not available in the native assembler.  If the native assembler is
 496   used, it should become obvious pretty quickly what the problem is.
 497
 498 * Usage message is available with "--help".
 499
 500 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 501   also, but didn't get into the NEWS file.)
 502
 503 * Weak symbol support for a.out.
 504
 505 * A bug in the listing code which could cause an infinite loop has been fixed.
 506   Bugs in listings when generating a COFF object file have also been fixed.
 507
 508 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 509   Paul Kranenburg.
 510
 511 * Improved Alpha support.  Immediate constants can have a much larger range
 512   now. Support for the 21164 has been contributed by Digital.
 513
 514 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 515
 516 Changes in 2.3:
 517
 518 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 519
 520 * RS/6000 and PowerPC support by Ian Taylor.
 521
 522 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 523   based on mail received from various people.  The `-h#' option should work
 524   again too.
 525
 526 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 527   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 528   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 529   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 530   in the "dist" directory.
 531
 532 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 533   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 534   currently required for BSD 4.3 builds.)
 535
 536 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 537   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 538   the alpha-a.out support is pretty badly mangled, and much of it removed;
 539   making it work will require rewriting it as BFD support for the format anyways.
 540
 541 * Irix 5 support.
 542
 543 * The test suites have been fixed up a bit, so that they should work with a
 544   couple different versions of expect and dejagnu.
 545
 546 * Symbols' values are now handled internally as expressions, permitting more
 547   flexibility in evaluating them in some cases.  Some details of relocation
 548   handling have also changed, and simple constant pool management has been
 549   added, to make the Alpha port easier.
 550
 551 * New option "--statistics" for printing out program run times.  This is
 552   intended to be used with the gcc "-Q" option, which prints out times spent in
 553   various phases of compilation.  (You should be able to get all of them
 554   printed out with "gcc -Q -Wa,--statistics", I think.)
 555
 556 Changes in 2.2:
 557
 558 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 559
 560 * Configurations that are still in development (and therefore are convenient to
 561   have listed in configure.in) still get rejected without a minor change to
 562   gas/Makefile.in, so people not doing development work shouldn't get the
 563   impression that support for such configurations is actually believed to be
 564   reliable.
 565
 566 * The program name (usually "as") is printed when a fatal error message is
 567   displayed.  This should prevent some confusion about the source of occasional
 568   messages about "internal errors".
 569
 570 * ELF support is falling into place.  Support for the 386 should be working.
 571   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 572
 573 * Symbol values are maintained as expressions instead of being immediately
 574   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 575   more complex calculations involving symbols whose values are not alreadey
 576   known.
 577
 578 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 579   If any stabs directives are seen in the source, GAS will create two new
 580   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 581   section is nearly identical to the a.out symbol format, and .stabstr is
 582   its string table.  For this to be useful, you must have configured GCC
 583   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 584   that can use the stab sections (4.11 or later).
 585
 586 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 587   support is in progress.
 588
 589 Changes in 2.1:
 590
 591 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 592   incorporated, but not well tested yet.
 593
 594 * Altered the opcode table split for m68k; it should require less VM to compile
 595   with gcc now.
 596
 597 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 598   suggested by Ronald Cole.
 599
 600 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 601   includes improved ELF support, which I've started adapting for SPARC Solaris
 602   2.x.  Integration isn't completely, so it probably won't work.
 603
 604 * HP9000/300 support, donated by HP, has been merged in.
 605
 606 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 607
 608 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 609
 610 * Test suite framework is starting to become reasonable.
 611
 612 Changes in 2.0:
 613
 614 * Mostly bug fixes.
 615
 616 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 617
 618 Changes in 1.94:
 619
 620 * BFD merge is partly done.  Adventurous souls may try giving configure the
 621   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 622   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 623   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 624   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 625   fully merged yet.)
 626
 627 * The 68K opcode table has been split in half.  It should now compile under gcc
 628   without consuming ridiculous amounts of memory.
 629
 630 * A couple data structures have been reduced in size.  This should result in
 631   saving a little bit of space at runtime.
 632
 633 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 634   code provided ROSE format support, which I haven't merged in yet.  (I can
 635   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 636   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 637   coming.
 638
 639 * Support for the Hitachi H8/500 has been added.
 640
 641 * VMS host and target support should be working now, thanks chiefly to Eric
 642   Youngdale.
 643
 644 Changes in 1.93.01:
 645
 646 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 647
 648 * For i386, .align is now power-of-two; was number-of-bytes.
 649
 650 * For m68k, "%" is now accepted before register names.  For COFF format, which
 651   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 652   can be distinguished from the register.
 653
 654 * Last public release was 1.38.  Lots of configuration changes since then, lots
 655   of new CPUs and formats, lots of bugs fixed.
