   2
   3 * New command line option -mfence-as-lock-add=yes for x86 target to encode
   4   lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
   5
   6 Changes in 2.26:
   7
   8 * Add a configure option --enable-compressed-debug-sections={all,gas} to
   9   decide whether DWARF debug sections should be compressed by default.
  10
  11 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  12   assembler support for Argonaut RISC architectures.
  13
  14 * Symbol and label names can now be enclosed in double quotes (") which allows
  15   them to contain characters that are not part of valid symbol names in high
  16   level languages.
  17
  18 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  19   previous spelling, -march=armv6zk, is still accepted.
  20
  21 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  22   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  23   extensions has also been added to the Aarch64 port.
  24
  25 * Support for the ARMv8.1 architecture has been added to the ARM port.  Support
  26   for the individual ARMv8.1 Adv.SIMD and PAN architecture extensions has also
  27   been added to the ARM port.
  28
  29 * Extend --compress-debug-sections option to support
  30   --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
  31   targets.
  32
  33 * --compress-debug-sections is turned on for Linux/x86 by default.
  34
  35 Changes in 2.25:
  36
  37 * Add support for the AVR Tiny microcontrollers.
  38
  39 * Replace support for openrisc and or32 with support for or1k.
  40
  41 * Enhanced the ARM port to accept the assembler output from the CodeComposer
  42   Studio tool.  Support is enabled via the new command line option -mccs.
  43
  44 * Add support for the Andes NDS32.
  45
  46 Changes in 2.24:
  47
  48 * Add support for the Texas Instruments MSP430X processor.
  49
  50 * Add -gdwarf-sections command line option to enable per-code-section
  51   generation of DWARF .debug_line sections.
  52
  53 * Add support for Altera Nios II.
  54
  55 * Add support for the Imagination Technologies Meta processor.
  56
  57 * Add support for the v850e3v5.
  58
  59 * Remove assembler support for MIPS ECOFF targets.
  60
  61 Changes in 2.23:
  62
  63 * Add support for the 64-bit ARM architecture: AArch64.
  64
  65 * Add support for S12X processor.
  66
  67 * Add support for the VLE extension to the PowerPC architecture.
  68
  69 * Add support for the Freescale XGATE architecture.
  70
  71 * Add support for .bundle_align_mode, .bundle_lock, and .bundle_unlock
  72   directives.  These are currently available only for x86 and ARM targets.
  73
  74 * Add support for the Renesas RL78 architecture.
  75
  76 * Add support for the Adapteva EPIPHANY architecture.
  77
  78 * For x86, allow 'rep bsf', 'rep bsr', and 'rep ret' syntax.
  79
  80 Changes in 2.22:
  81
  82 * Add support for the Tilera TILEPro and TILE-Gx architectures.
  83
  84 Changes in 2.21:
  85
  86 * Gas no longer requires doubling of ampersands in macros.
  87
  88 * Add support for the TMS320C6000 (TI C6X) processor family.
  89
  90 * GAS now understands an extended syntax in the .section directive flags
  91   for COFF targets that allows the section's alignment to be specified.  This
  92   feature has also been backported to the 2.20 release series, starting with
  93   2.20.1.
  94
  95 * Add support for the Renesas RX processor.
  96
  97 * New command line option, --compress-debug-sections, which requests
  98   compression of DWARF debug information sections in the relocatable output
  99   file.  Compressed debug sections are supported by readelf, objdump, and
 100   gold, but not currently by Gnu ld.
 101
 102 Changes in 2.20:
 103
 104 * Added support for v850e2 and v850e2v3.
 105
 106 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 107   pseudo op.  It marks the symbol as being globally unique in the entire
 108   process.
 109
 110 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 111   in binary rather than text.
 112
 113 * Add support for common symbol alignment to PE formats.
 114
 115 * Add support for the new discriminator column in the DWARF line table,
 116   with a discriminator operand for the .loc directive.
 117
 118 * Add support for Sunplus score architecture.
 119
 120 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 121   indicate that if the symbol is the target of a relocation, its value should
 122   not be use.  Instead the function should be invoked and its result used as
 123   the value.
 124
 125 * Add support for Lattice Mico32 (lm32) architecture.
 126
 127 * Add support for Xilinx MicroBlaze architecture.
 128
 129 Changes in 2.19:
 130
 131 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 132   tables without runtime relocation.
 133
 134 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 135   adds compatibility with H'00 style hex constants.
 136
 137 * New command line option, -msse-check=[none|error|warning], for x86
 138   targets.
 139
 140 * New sub-option added to the assembler's -a command line switch to
 141   generate a listing output.  The 'g' sub-option will insert into the listing
 142   various information about the assembly, such as assembler version, the
 143   command line options used, and a time stamp.
 144
 145 * New command line option -msse2avx for x86 target to encode SSE
 146   instructions with VEX prefix.
 147
 148 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 149
 150 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 151   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 152   -mnaked-reg and -mold-gcc, for x86 targets.
 153
 154 * Support for generating wide character strings has been added via the new
 155   pseudo ops: .string16, .string32 and .string64.
 156
 157 * Support for SSE5 has been added to the i386 port.
 158
 159 Changes in 2.18:
 160
 161 * The GAS sources are now released under the GPLv3.
 162
 163 * Support for the National Semiconductor CR16 target has been added.
 164
 165 * Added gas .reloc pseudo.  This is a low-level interface for creating
 166   relocations.
 167
 168 * Add support for x86_64 PE+ target.
 169
 170 * Add support for Score target.
 171
 172 Changes in 2.17:
 173
 174 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 175
 176 * Support for ms2 architecture has been added.
 177
 178 * Support for the Z80 processor family has been added.
 179
 180 * Add support for the "@<file>" syntax to the command line, so that extra
 181   switches can be read from <file>.
 182
 183 * The SH target supports a new command line switch --enable-reg-prefix which,
 184   if enabled, will allow register names to be optionally prefixed with a $
 185   character.  This allows register names to be distinguished from label names.
 186
 187 * Macros with a variable number of arguments are now supported. See the
 188   documentation for how this works.
 189
 190 * Added --reduce-memory-overheads switch to reduce the size of the hash
 191   tables used, at the expense of longer assembly times, and
 192   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 193
 194 * Macro names and macro parameter names can now be any identifier that would
 195   also be legal as a symbol elsewhere. For macro parameter names, this is
 196   known to cause problems in certain sources when the respective target uses
 197   characters inconsistently, and thus macro parameter references may no longer
 198   be recognized as such (see the documentation for details).
 199
 200 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 201   for the VAX target in order to be more compatible with the VAX MACRO
 202   assembler.
 203
 204 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 205
 206 Changes in 2.16:
 207
 208 * Redefinition of macros now results in an error.
 209
 210 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 211
 212 * New command line option -munwind-check=[warning|error] for IA64
 213   targets.
 214
 215 * The IA64 port now uses automatic dependency violation removal as its default
 216   mode.
 217
 218 * Port to MAXQ processor contributed by HCL Tech.
 219
 220 * Added support for generating unwind tables for ARM ELF targets.
 221
 222 * Add a -g command line option to generate debug information in the target's
 223   preferred debug format.
 224
 225 * Support for the crx-elf target added.
 226
 227 * Support for the sh-symbianelf target added.
 228
 229 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 230   on pe[i]-i386; required for this target's DWARF 2 support.
 231
 232 * Support for Motorola MCF521x/5249/547x/548x added.
 233
 234 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 235   instrucitons.
 236
 237 * New command line option -mno-shared for MIPS ELF targets.
 238
 239 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 240   added to enter (and leave) alternate macro syntax mode.
 241
 242 Changes in 2.15:
 243
 244 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 245   deprecated and will be removed in a future release.
 246
 247 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 248
 249 * Added support for ARM V6.
 250
 251 * Added support for sh4a and variants.
 252
 253 * Support for Renesas M32R2 added.
 254
 255 * Limited support for Mapping Symbols as specified in the ARM ELF
 256   specification has been added to the arm assembler.
 257
 258 * On ARM architectures, added a new gas directive ".unreq" that undoes
 259   definitions created by ".req".
 260
 261 * Support for Motorola ColdFire MCF528x added.
 262
 263 * Added --gstabs+ switch to enable the generation of STABS debug format
 264   information with GNU extensions.
 265
 266 * Added support for MIPS64 Release 2.
 267
 268 * Added support for v850e1.
 269
 270 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 271   multiple nop instructions used for alignment within code sections
 272   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 273   switch disables the optimization.
 274
 275 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 276   existing -non_shared option.
 277
 278 Changes in 2.14:
 279
 280 * Added support for MIPS32 Release 2.
 281
 282 * Added support for Xtensa architecture.
 283
 284 * Support for Intel's iWMMXt processor (an ARM variant) added.
 285
 286 * An assembler test generator has been contributed and an example file that
 287   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 288
 289 * Support for SH2E added.
 290
 291 * GASP has now been removed.
 292
 293 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 294   DSP's contributed by Michael Hayes and Svein E. Seldal.
 295
 296 * Support for the Ubicom IP2xxx microcontroller added.
 297
 298 Changes in 2.13:
 299
 300 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 301   and FR500 included.
 302
 303 * Support for DLX processor added.
 304
 305 * GASP has now been deprecated and will be removed in a future release.  Use
 306   the macro facilities in GAS instead.
 307
 308 * GASP now correctly parses floating point numbers. Unless the base is
 309   explicitly specified, they are interpreted as decimal numbers regardless of
 310   the currently specified base.
 311
 312 Changes in 2.12:
 313
 314 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 315
 316 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 317
 318 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 319   specifying the target instruction set.  The old method of specifying the
 320   target processor has been deprecated, but is still accepted for
 321   compatibility.
 322
 323 * Support for the VFP floating-point instruction set has been added to
 324   the ARM assembler.
 325
 326 * New psuedo op: .incbin to include a set of binary data at a given point
 327   in the assembly.  Contributed by Anders Norlander.
 328
 329 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 330   but still works for compatability.
 331
 332 * The MIPS assembler no longer issues a warning by default when it
 333   generates a nop instruction from a macro. The new command line option
 334   -n will turn on the warning.
 335
 336 Changes in 2.11:
 337
 338 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 339
 340 * x86 gas now supports the full Pentium4 instruction set.
 341
 342 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 343
 344 * Support for Motorola 68HC11 and 68HC12.
 345
 346 * Support for Texas Instruments TMS320C54x (tic54x).
 347
 348 * Support for IA-64.
 349
 350 * Support for i860, by Jason Eckhardt.
 351
 352 * Support for CRIS (Axis Communications ETRAX series).
 353
 354 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 355
 356 * x86 gas -q command line option quietens warnings about register size changes
 357   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 358   translating various deprecated floating point instructions.
 359
 360 Changes in 2.10:
 361
 362 * Support for the ARM msr instruction was changed to only allow an immediate
 363   operand when altering the flags field.
 364
 365 * Support for ATMEL AVR.
 366
 367 * Support for IBM 370 ELF.  Somewhat experimental.
 368
 369 * Support for numbers with suffixes.
 370
 371 * Added support for breaking to the end of repeat loops.
 372
 373 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 374
 375 * New .elseif pseudo-op added.
 376
 377 * New --fatal-warnings option.
 378
 379 * picoJava architecture support added.
 380
 381 * Motorola MCore 210 processor support added.
 382
 383 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 384   assembly programs with intel syntax.
 385
 386 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 387
 388 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 389
 390 * Full 16-bit mode support for i386.
 391
 392 * Greatly improved instruction operand checking for i386.  This change will
 393   produce errors or warnings on incorrect assembly code that previous versions
 394   of gas accepted.  If you get unexpected messages from code that worked with
 395   older versions of gas, please double check the code before reporting a bug.
 396
 397 * Weak symbol support added for COFF targets.
 398
 399 * Mitsubishi D30V support added.
 400
 401 * Texas Instruments c80 (tms320c80) support added.
 402
 403 * i960 ELF support added.
 404
 405 * ARM ELF support added.
 406
 407 Changes in 2.9:
 408
 409 * Texas Instruments c30 (tms320c30) support added.
 410
 411 * The assembler now optimizes the exception frame information generated by egcs
 412   and gcc 2.8.  The new --traditional-format option disables this optimization.
 413
 414 * Added --gstabs option to generate stabs debugging information.
 415
 416 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 417   listing.
 418
 419 * Added -MD option to print dependencies.
 420
 421 Changes in 2.8:
 422
 423 * BeOS support added.
 424
 425 * MIPS16 support added.
 426
 427 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 428
 429 * Alpha/VMS support added.
 430
 431 * m68k options --base-size-default-16, --base-size-default-32,
 432   --disp-size-default-16, and --disp-size-default-32 added.
 433
 434 * The alignment directives now take an optional third argument, which is the
 435   maximum number of bytes to skip.  If doing the alignment would require
 436   skipping more than the given number of bytes, the alignment is not done at
 437   all.
 438
 439 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 440
 441 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 442   conditionals in listings.
 443
 444 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 445   the symbol is already defined.
 446
 447 Changes in 2.7:
 448
 449 * The PowerPC assembler now allows the use of symbolic register names (r0,
 450   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 451   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 452   added.
 453
 454 * Alpha Linux (ELF) support added.
 455
 456 * PowerPC ELF support added.
 457
 458 * m68k Linux (ELF) support added.
 459
 460 * i960 Hx/Jx support added.
 461
 462 * i386/PowerPC gnu-win32 support added.
 463
 464 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 465   default is to build COFF-only support.  To get a set of tools that generate
 466   ELF (they'll understand both COFF and ELF), you must configure with
 467   target=i386-unknown-sco3.2v5elf.
 468
 469 * m88k-motorola-sysv3* support added.
 470
 471 Changes in 2.6:
 472
 473 * Gas now directly supports macros, without requiring GASP.
 474
 475 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 476   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 477   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 478
 479 * Added --defsym SYM=VALUE option.
 480
 481 * Added -mips4 support to MIPS assembler.
 482
 483 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 484
 485 Changes in 2.4:
 486
 487 * Converted this directory to use an autoconf-generated configure script.
 488
 489 * ARM support, from Richard Earnshaw.
 490
 491 * Updated VMS support, from Pat Rankin, including considerably improved
 492   debugging support.
 493
 494 * Support for the control registers in the 68060.
 495
 496 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 497   provide for possible future gcc changes, for targets where gas provides some
 498   features not available in the native assembler.  If the native assembler is
 499   used, it should become obvious pretty quickly what the problem is.
 500
 501 * Usage message is available with "--help".
 502
 503 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 504   also, but didn't get into the NEWS file.)
 505
 506 * Weak symbol support for a.out.
 507
 508 * A bug in the listing code which could cause an infinite loop has been fixed.
 509   Bugs in listings when generating a COFF object file have also been fixed.
 510
 511 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 512   Paul Kranenburg.
 513
 514 * Improved Alpha support.  Immediate constants can have a much larger range
 515   now. Support for the 21164 has been contributed by Digital.
 516
 517 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 518
 519 Changes in 2.3:
 520
 521 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 522
 523 * RS/6000 and PowerPC support by Ian Taylor.
 524
 525 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 526   based on mail received from various people.  The `-h#' option should work
 527   again too.
 528
 529 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 530   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 531   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 532   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 533   in the "dist" directory.
 534
 535 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 536   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 537   currently required for BSD 4.3 builds.)
 538
 539 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 540   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 541   the alpha-a.out support is pretty badly mangled, and much of it removed;
 542   making it work will require rewriting it as BFD support for the format anyways.
 543
 544 * Irix 5 support.
 545
 546 * The test suites have been fixed up a bit, so that they should work with a
 547   couple different versions of expect and dejagnu.
 548
 549 * Symbols' values are now handled internally as expressions, permitting more
 550   flexibility in evaluating them in some cases.  Some details of relocation
 551   handling have also changed, and simple constant pool management has been
 552   added, to make the Alpha port easier.
 553
 554 * New option "--statistics" for printing out program run times.  This is
 555   intended to be used with the gcc "-Q" option, which prints out times spent in
 556   various phases of compilation.  (You should be able to get all of them
 557   printed out with "gcc -Q -Wa,--statistics", I think.)
 558
 559 Changes in 2.2:
 560
 561 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 562
 563 * Configurations that are still in development (and therefore are convenient to
 564   have listed in configure.in) still get rejected without a minor change to
 565   gas/Makefile.in, so people not doing development work shouldn't get the
 566   impression that support for such configurations is actually believed to be
 567   reliable.
 568
 569 * The program name (usually "as") is printed when a fatal error message is
 570   displayed.  This should prevent some confusion about the source of occasional
 571   messages about "internal errors".
 572
 573 * ELF support is falling into place.  Support for the 386 should be working.
 574   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 575
 576 * Symbol values are maintained as expressions instead of being immediately
 577   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 578   more complex calculations involving symbols whose values are not alreadey
 579   known.
 580
 581 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 582   If any stabs directives are seen in the source, GAS will create two new
 583   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 584   section is nearly identical to the a.out symbol format, and .stabstr is
 585   its string table.  For this to be useful, you must have configured GCC
 586   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 587   that can use the stab sections (4.11 or later).
 588
 589 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 590   support is in progress.
 591
 592 Changes in 2.1:
 593
 594 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 595   incorporated, but not well tested yet.
 596
 597 * Altered the opcode table split for m68k; it should require less VM to compile
 598   with gcc now.
 599
 600 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 601   suggested by Ronald Cole.
 602
 603 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 604   includes improved ELF support, which I've started adapting for SPARC Solaris
 605   2.x.  Integration isn't completely, so it probably won't work.
 606
 607 * HP9000/300 support, donated by HP, has been merged in.
 608
 609 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 610
 611 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 612
 613 * Test suite framework is starting to become reasonable.
 614
 615 Changes in 2.0:
 616
 617 * Mostly bug fixes.
 618
 619 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 620
 621 Changes in 1.94:
 622
 623 * BFD merge is partly done.  Adventurous souls may try giving configure the
 624   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 625   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 626   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 627   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 628   fully merged yet.)
 629
 630 * The 68K opcode table has been split in half.  It should now compile under gcc
 631   without consuming ridiculous amounts of memory.
 632
 633 * A couple data structures have been reduced in size.  This should result in
 634   saving a little bit of space at runtime.
 635
 636 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 637   code provided ROSE format support, which I haven't merged in yet.  (I can
 638   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 639   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 640   coming.
 641
 642 * Support for the Hitachi H8/500 has been added.
 643
 644 * VMS host and target support should be working now, thanks chiefly to Eric
 645   Youngdale.
 646
 647 Changes in 1.93.01:
 648
 649 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 650
 651 * For i386, .align is now power-of-two; was number-of-bytes.
 652
 653 * For m68k, "%" is now accepted before register names.  For COFF format, which
 654   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 655   can be distinguished from the register.
 656
 657 * Last public release was 1.38.  Lots of configuration changes since then, lots
 658   of new CPUs and formats, lots of bugs fixed.
