   3 Changes in 2.27:
   4
   5 * Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
   6
   7 * Add --no-pad-sections to stop the assembler from padding the end of output
   8   sections up to their alignment boundary.
   9
  10 * Support for the ARMv8-M architecture has been added to the ARM port.  Support
  11   for the ARMv8-M Security and DSP Extensions has also been added to the ARM
  12   port.
  13
  14 * ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
  15   .extCoreRegister pseudo-ops that allow an user to define custom
  16   instructions, conditional codes, auxiliary and core registers.
  17
  18 * Add a configure option --enable-elf-stt-common to decide whether ELF
  19   assembler should generate common symbols with the STT_COMMON type by
  20   default.  Default to no.
  21
  22 * New command line option --elf-stt-common= for ELF targets to control
  23   whether to generate common symbols with the STT_COMMON type.
  24
  25 * Add ability to set section flags and types via numeric values for ELF
  26   based targets.
  27
  28 * Add a configure option --enable-x86-relax-relocations to decide whether
  29   x86 assembler should generate relax relocations by default.  Default to
  30   yes, except for x86 Solaris targets older than Solaris 12.
  31
  32 * New command line option -mrelax-relocations= for x86 target to control
  33   whether to generate relax relocations.
  34
  35 * New command line option -mfence-as-lock-add=yes for x86 target to encode
  36   lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
  37
  38 * Add assembly-time relaxation option for ARC cpus.
  39
  40 * Add --with-cpu=TYPE configure option for ARC gas.  This allows the default
  41   cpu type to be adjusted at configure time.
  42
  43 Changes in 2.26:
  44
  45 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  46   decide whether DWARF debug sections should be compressed by default.
  47
  48 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  49   assembler support for Argonaut RISC architectures.
  50
  51 * Symbol and label names can now be enclosed in double quotes (") which allows
  52   them to contain characters that are not part of valid symbol names in high
  53   level languages.
  54
  55 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  56   previous spelling, -march=armv6zk, is still accepted.
  57
  58 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  59   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  60   extensions has also been added to the Aarch64 port.
  61
  62 * Support for the ARMv8.1 architecture has been added to the ARM port.  Support
  63   for the individual ARMv8.1 Adv.SIMD and PAN architecture extensions has also
  64   been added to the ARM port.
  65

  88   generation of DWARF .debug_line sections.
  89
  90 * Add support for Altera Nios II.
  91
  92 * Add support for the Imagination Technologies Meta processor.
  93
  94 * Add support for the v850e3v5.
  95
  96 * Remove assembler support for MIPS ECOFF targets.
  97
  98 Changes in 2.23:

 120
 121 Changes in 2.21:
 122
 123 * Gas no longer requires doubling of ampersands in macros.
 124
 125 * Add support for the TMS320C6000 (TI C6X) processor family.
 126
 127 * GAS now understands an extended syntax in the .section directive flags
 128   for COFF targets that allows the section's alignment to be specified.  This
 129   feature has also been backported to the 2.20 release series, starting with
 130   2.20.1.
 131
 132 * Add support for the Renesas RX processor.
 133
 134 * New command line option, --compress-debug-sections, which requests
 135   compression of DWARF debug information sections in the relocatable output
 136   file.  Compressed debug sections are supported by readelf, objdump, and
 137   gold, but not currently by Gnu ld.
 138
 139 Changes in 2.20:
 140
 141 * Added support for v850e2 and v850e2v3.
 142
 143 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 144   pseudo op.  It marks the symbol as being globally unique in the entire
 145   process.
 146
 147 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 148   in binary rather than text.
 149
 150 * Add support for common symbol alignment to PE formats.
 151
 152 * Add support for the new discriminator column in the DWARF line table,
 153   with a discriminator operand for the .loc directive.
 154
 155 * Add support for Sunplus score architecture.
 156
 157 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 158   indicate that if the symbol is the target of a relocation, its value should
 159   not be use.  Instead the function should be invoked and its result used as
 160   the value.
 161
 162 * Add support for Lattice Mico32 (lm32) architecture.
 163
 164 * Add support for Xilinx MicroBlaze architecture.
 165
 166 Changes in 2.19:
 167
 168 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 169   tables without runtime relocation.
 170
 171 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 172   adds compatibility with H'00 style hex constants.
 173
 174 * New command line option, -msse-check=[none|error|warning], for x86
 175   targets.
 176
 177 * New sub-option added to the assembler's -a command line switch to
 178   generate a listing output.  The 'g' sub-option will insert into the listing
 179   various information about the assembly, such as assembler version, the
 180   command line options used, and a time stamp.
 181
 182 * New command line option -msse2avx for x86 target to encode SSE
 183   instructions with VEX prefix.
 184
 185 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 186
 187 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 188   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 189   -mnaked-reg and -mold-gcc, for x86 targets.
 190
 191 * Support for generating wide character strings has been added via the new
 192   pseudo ops: .string16, .string32 and .string64.
 193
 194 * Support for SSE5 has been added to the i386 port.
 195
 196 Changes in 2.18:
 197
 198 * The GAS sources are now released under the GPLv3.
 199
 200 * Support for the National Semiconductor CR16 target has been added.
 201
 202 * Added gas .reloc pseudo.  This is a low-level interface for creating
 203   relocations.
 204
 205 * Add support for x86_64 PE+ target.
 206
 207 * Add support for Score target.
 208
 209 Changes in 2.17:
 210
 211 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 212
 213 * Support for ms2 architecture has been added.
 214
 215 * Support for the Z80 processor family has been added.
 216
 217 * Add support for the "@<file>" syntax to the command line, so that extra
 218   switches can be read from <file>.
 219
 220 * The SH target supports a new command line switch --enable-reg-prefix which,
 221   if enabled, will allow register names to be optionally prefixed with a $
 222   character.  This allows register names to be distinguished from label names.
 223
 224 * Macros with a variable number of arguments are now supported. See the
 225   documentation for how this works.
 226
 227 * Added --reduce-memory-overheads switch to reduce the size of the hash
 228   tables used, at the expense of longer assembly times, and
 229   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 230
 231 * Macro names and macro parameter names can now be any identifier that would
 232   also be legal as a symbol elsewhere. For macro parameter names, this is
 233   known to cause problems in certain sources when the respective target uses
 234   characters inconsistently, and thus macro parameter references may no longer
 235   be recognized as such (see the documentation for details).
 236
 237 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 238   for the VAX target in order to be more compatible with the VAX MACRO
 239   assembler.
 240
 241 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 242
 243 Changes in 2.16:
 244
 245 * Redefinition of macros now results in an error.
 246
 247 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 248
 249 * New command line option -munwind-check=[warning|error] for IA64
 250   targets.
 251
 252 * The IA64 port now uses automatic dependency violation removal as its default
 253   mode.
 254
 255 * Port to MAXQ processor contributed by HCL Tech.
 256
 257 * Added support for generating unwind tables for ARM ELF targets.
 258
 259 * Add a -g command line option to generate debug information in the target's
 260   preferred debug format.
 261
 262 * Support for the crx-elf target added.
 263
 264 * Support for the sh-symbianelf target added.
 265
 266 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 267   on pe[i]-i386; required for this target's DWARF 2 support.
 268
 269 * Support for Motorola MCF521x/5249/547x/548x added.
 270
 271 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 272   instrucitons.
 273
 274 * New command line option -mno-shared for MIPS ELF targets.
 275
 276 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 277   added to enter (and leave) alternate macro syntax mode.
 278
 279 Changes in 2.15:
 280
 281 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 282   deprecated and will be removed in a future release.
 283
 284 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 285
 286 * Added support for ARM V6.
 287
 288 * Added support for sh4a and variants.
 289
 290 * Support for Renesas M32R2 added.
 291
 292 * Limited support for Mapping Symbols as specified in the ARM ELF
 293   specification has been added to the arm assembler.
 294
 295 * On ARM architectures, added a new gas directive ".unreq" that undoes
 296   definitions created by ".req".
 297
 298 * Support for Motorola ColdFire MCF528x added.
 299
 300 * Added --gstabs+ switch to enable the generation of STABS debug format
 301   information with GNU extensions.
 302
 303 * Added support for MIPS64 Release 2.
 304
 305 * Added support for v850e1.
 306
 307 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 308   multiple nop instructions used for alignment within code sections
 309   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 310   switch disables the optimization.
 311
 312 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 313   existing -non_shared option.
 314
 315 Changes in 2.14:
 316
 317 * Added support for MIPS32 Release 2.
 318
 319 * Added support for Xtensa architecture.
 320
 321 * Support for Intel's iWMMXt processor (an ARM variant) added.
 322
 323 * An assembler test generator has been contributed and an example file that
 324   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 325
 326 * Support for SH2E added.
 327
 328 * GASP has now been removed.
 329
 330 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 331   DSP's contributed by Michael Hayes and Svein E. Seldal.
 332
 333 * Support for the Ubicom IP2xxx microcontroller added.
 334
 335 Changes in 2.13:
 336
 337 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 338   and FR500 included.
 339
 340 * Support for DLX processor added.
 341
 342 * GASP has now been deprecated and will be removed in a future release.  Use
 343   the macro facilities in GAS instead.
 344
 345 * GASP now correctly parses floating point numbers. Unless the base is
 346   explicitly specified, they are interpreted as decimal numbers regardless of
 347   the currently specified base.
 348
 349 Changes in 2.12:
 350
 351 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 352
 353 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 354
 355 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 356   specifying the target instruction set.  The old method of specifying the
 357   target processor has been deprecated, but is still accepted for
 358   compatibility.
 359
 360 * Support for the VFP floating-point instruction set has been added to
 361   the ARM assembler.
 362
 363 * New psuedo op: .incbin to include a set of binary data at a given point
 364   in the assembly.  Contributed by Anders Norlander.
 365
 366 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 367   but still works for compatability.
 368
 369 * The MIPS assembler no longer issues a warning by default when it
 370   generates a nop instruction from a macro. The new command line option
 371   -n will turn on the warning.
 372
 373 Changes in 2.11:
 374
 375 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 376
 377 * x86 gas now supports the full Pentium4 instruction set.
 378
 379 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 380
 381 * Support for Motorola 68HC11 and 68HC12.
 382
 383 * Support for Texas Instruments TMS320C54x (tic54x).
 384
 385 * Support for IA-64.
 386
 387 * Support for i860, by Jason Eckhardt.
 388
 389 * Support for CRIS (Axis Communications ETRAX series).
 390
 391 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 392
 393 * x86 gas -q command line option quietens warnings about register size changes
 394   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 395   translating various deprecated floating point instructions.
 396
 397 Changes in 2.10:
 398
 399 * Support for the ARM msr instruction was changed to only allow an immediate
 400   operand when altering the flags field.
 401
 402 * Support for ATMEL AVR.
 403
 404 * Support for IBM 370 ELF.  Somewhat experimental.
 405
 406 * Support for numbers with suffixes.
 407
 408 * Added support for breaking to the end of repeat loops.
 409
 410 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 411
 412 * New .elseif pseudo-op added.
 413
 414 * New --fatal-warnings option.
 415
 416 * picoJava architecture support added.
 417
 418 * Motorola MCore 210 processor support added.
 419
 420 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 421   assembly programs with intel syntax.
 422
 423 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 424
 425 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 426
 427 * Full 16-bit mode support for i386.
 428
 429 * Greatly improved instruction operand checking for i386.  This change will
 430   produce errors or warnings on incorrect assembly code that previous versions
 431   of gas accepted.  If you get unexpected messages from code that worked with
 432   older versions of gas, please double check the code before reporting a bug.
 433
 434 * Weak symbol support added for COFF targets.
 435
 436 * Mitsubishi D30V support added.
 437
 438 * Texas Instruments c80 (tms320c80) support added.
 439
 440 * i960 ELF support added.
 441
 442 * ARM ELF support added.
 443
 444 Changes in 2.9:
 445
 446 * Texas Instruments c30 (tms320c30) support added.
 447
 448 * The assembler now optimizes the exception frame information generated by egcs
 449   and gcc 2.8.  The new --traditional-format option disables this optimization.
 450
 451 * Added --gstabs option to generate stabs debugging information.
 452
 453 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 454   listing.
 455
 456 * Added -MD option to print dependencies.
 457
 458 Changes in 2.8:
 459
 460 * BeOS support added.
 461
 462 * MIPS16 support added.
 463
 464 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 465
 466 * Alpha/VMS support added.
 467
 468 * m68k options --base-size-default-16, --base-size-default-32,
 469   --disp-size-default-16, and --disp-size-default-32 added.
 470
 471 * The alignment directives now take an optional third argument, which is the
 472   maximum number of bytes to skip.  If doing the alignment would require
 473   skipping more than the given number of bytes, the alignment is not done at
 474   all.
 475
 476 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 477
 478 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 479   conditionals in listings.
 480
 481 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 482   the symbol is already defined.
 483
 484 Changes in 2.7:
 485
 486 * The PowerPC assembler now allows the use of symbolic register names (r0,
 487   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 488   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 489   added.
 490
 491 * Alpha Linux (ELF) support added.
 492
 493 * PowerPC ELF support added.
 494
 495 * m68k Linux (ELF) support added.
 496
 497 * i960 Hx/Jx support added.
 498
 499 * i386/PowerPC gnu-win32 support added.
 500
 501 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 502   default is to build COFF-only support.  To get a set of tools that generate
 503   ELF (they'll understand both COFF and ELF), you must configure with
 504   target=i386-unknown-sco3.2v5elf.
 505
 506 * m88k-motorola-sysv3* support added.
 507
 508 Changes in 2.6:
 509
 510 * Gas now directly supports macros, without requiring GASP.
 511
 512 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 513   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 514   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 515
 516 * Added --defsym SYM=VALUE option.
 517
 518 * Added -mips4 support to MIPS assembler.
 519
 520 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 521
 522 Changes in 2.4:
 523
 524 * Converted this directory to use an autoconf-generated configure script.
 525
 526 * ARM support, from Richard Earnshaw.
 527
 528 * Updated VMS support, from Pat Rankin, including considerably improved
 529   debugging support.
 530
 531 * Support for the control registers in the 68060.
 532
 533 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 534   provide for possible future gcc changes, for targets where gas provides some
 535   features not available in the native assembler.  If the native assembler is
 536   used, it should become obvious pretty quickly what the problem is.
 537
 538 * Usage message is available with "--help".
 539
 540 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 541   also, but didn't get into the NEWS file.)
 542
 543 * Weak symbol support for a.out.
 544
 545 * A bug in the listing code which could cause an infinite loop has been fixed.
 546   Bugs in listings when generating a COFF object file have also been fixed.
 547
 548 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 549   Paul Kranenburg.
 550
 551 * Improved Alpha support.  Immediate constants can have a much larger range
 552   now. Support for the 21164 has been contributed by Digital.
 553
 554 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.

 556 Changes in 2.3:
 557
 558 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 559
 560 * RS/6000 and PowerPC support by Ian Taylor.
 561
 562 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 563   based on mail received from various people.  The `-h#' option should work
 564   again too.
 565
 566 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 567   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 568   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 569   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 570   in the "dist" directory.
 571
 572 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 573   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 574   currently required for BSD 4.3 builds.)
 575
 576 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 577   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 578   the alpha-a.out support is pretty badly mangled, and much of it removed;
 579   making it work will require rewriting it as BFD support for the format anyways.
 580
 581 * Irix 5 support.
 582
 583 * The test suites have been fixed up a bit, so that they should work with a
 584   couple different versions of expect and dejagnu.
 585
 586 * Symbols' values are now handled internally as expressions, permitting more
 587   flexibility in evaluating them in some cases.  Some details of relocation
 588   handling have also changed, and simple constant pool management has been
 589   added, to make the Alpha port easier.
 590
 591 * New option "--statistics" for printing out program run times.  This is
 592   intended to be used with the gcc "-Q" option, which prints out times spent in
 593   various phases of compilation.  (You should be able to get all of them
 594   printed out with "gcc -Q -Wa,--statistics", I think.)
 595
 596 Changes in 2.2:
 597
 598 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 599
 600 * Configurations that are still in development (and therefore are convenient to
 601   have listed in configure.in) still get rejected without a minor change to
 602   gas/Makefile.in, so people not doing development work shouldn't get the
 603   impression that support for such configurations is actually believed to be
 604   reliable.
 605
 606 * The program name (usually "as") is printed when a fatal error message is
 607   displayed.  This should prevent some confusion about the source of occasional
 608   messages about "internal errors".
 609
 610 * ELF support is falling into place.  Support for the 386 should be working.
 611   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 612
 613 * Symbol values are maintained as expressions instead of being immediately
 614   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 615   more complex calculations involving symbols whose values are not alreadey
 616   known.
 617
 618 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 619   If any stabs directives are seen in the source, GAS will create two new
 620   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 621   section is nearly identical to the a.out symbol format, and .stabstr is
 622   its string table.  For this to be useful, you must have configured GCC
 623   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 624   that can use the stab sections (4.11 or later).
 625
 626 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 627   support is in progress.
 628
 629 Changes in 2.1:
 630
 631 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 632   incorporated, but not well tested yet.
 633
 634 * Altered the opcode table split for m68k; it should require less VM to compile
 635   with gcc now.
 636
 637 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 638   suggested by Ronald Cole.
 639
 640 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 641   includes improved ELF support, which I've started adapting for SPARC Solaris
 642   2.x.  Integration isn't completely, so it probably won't work.
 643
 644 * HP9000/300 support, donated by HP, has been merged in.
 645
 646 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 647
 648 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 649
 650 * Test suite framework is starting to become reasonable.
 651
 652 Changes in 2.0:
 653
 654 * Mostly bug fixes.
 655
 656 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 657
 658 Changes in 1.94:
 659
 660 * BFD merge is partly done.  Adventurous souls may try giving configure the
 661   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 662   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 663   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 664   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 665   fully merged yet.)
 666
 667 * The 68K opcode table has been split in half.  It should now compile under gcc
 668   without consuming ridiculous amounts of memory.
 669
 670 * A couple data structures have been reduced in size.  This should result in
 671   saving a little bit of space at runtime.
 672
 673 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 674   code provided ROSE format support, which I haven't merged in yet.  (I can
 675   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 676   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 677   coming.
 678
 679 * Support for the Hitachi H8/500 has been added.
 680
 681 * VMS host and target support should be working now, thanks chiefly to Eric
 682   Youngdale.
 683
 684 Changes in 1.93.01:
 685
 686 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 687
 688 * For i386, .align is now power-of-two; was number-of-bytes.
 689
 690 * For m68k, "%" is now accepted before register names.  For COFF format, which
 691   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 692   can be distinguished from the register.
 693
 694 * Last public release was 1.38.  Lots of configuration changes since then, lots
 695   of new CPUs and formats, lots of bugs fixed.
