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