   2
   3 * Add a configure option --enable-x86-relax-relocations to decide whether
   4   x86 assembler should generate relax relocations by default.  Default to
   5   yes, except for x86 Solaris targets older than Solaris 12.
   6
   7 * New command line option -mrelax-relocations= for x86 target to control
   8   whether to generate relax relocations.
   9
  10 * New command line option -mfence-as-lock-add=yes for x86 target to encode
  11   lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
  12
  13 Changes in 2.26:
  14
  15 * Add a configure option --enable-compressed-debug-sections={all,gas} to
  16   decide whether DWARF debug sections should be compressed by default.
  17
  18 * Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  19   assembler support for Argonaut RISC architectures.
  20
  21 * Symbol and label names can now be enclosed in double quotes (") which allows
  22   them to contain characters that are not part of valid symbol names in high
  23   level languages.
  24
  25 * Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
  26   previous spelling, -march=armv6zk, is still accepted.
  27
  28 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
  29   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
  30   extensions has also been added to the Aarch64 port.
  31
  32 * Support for the ARMv8.1 architecture has been added to the ARM port.  Support
  33   for the individual ARMv8.1 Adv.SIMD and PAN architecture extensions has also
  34   been added to the ARM port.
  35
  36 * Extend --compress-debug-sections option to support
  37   --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
  38   targets.
  39
  40 * --compress-debug-sections is turned on for Linux/x86 by default.

  49   Studio tool.  Support is enabled via the new command line option -mccs.
  50
  51 * Add support for the Andes NDS32.
  52
  53 Changes in 2.24:
  54
  55 * Add support for the Texas Instruments MSP430X processor.
  56
  57 * Add -gdwarf-sections command line option to enable per-code-section
  58   generation of DWARF .debug_line sections.
  59
  60 * Add support for Altera Nios II.
  61
  62 * Add support for the Imagination Technologies Meta processor.
  63
  64 * Add support for the v850e3v5.
  65
  66 * Remove assembler support for MIPS ECOFF targets.
  67
  68 Changes in 2.23:
  69
  70 * Add support for the 64-bit ARM architecture: AArch64.
  71
  72 * Add support for S12X processor.
  73
  74 * Add support for the VLE extension to the PowerPC architecture.
  75
  76 * Add support for the Freescale XGATE architecture.
  77
  78 * Add support for .bundle_align_mode, .bundle_lock, and .bundle_unlock

  80
  81 * Add support for the Renesas RL78 architecture.
  82
  83 * Add support for the Adapteva EPIPHANY architecture.
  84
  85 * For x86, allow 'rep bsf', 'rep bsr', and 'rep ret' syntax.
  86
  87 Changes in 2.22:
  88
  89 * Add support for the Tilera TILEPro and TILE-Gx architectures.
  90
  91 Changes in 2.21:
  92
  93 * Gas no longer requires doubling of ampersands in macros.
  94
  95 * Add support for the TMS320C6000 (TI C6X) processor family.
  96
  97 * GAS now understands an extended syntax in the .section directive flags
  98   for COFF targets that allows the section's alignment to be specified.  This
  99   feature has also been backported to the 2.20 release series, starting with
 100   2.20.1.
 101
 102 * Add support for the Renesas RX processor.
 103
 104 * New command line option, --compress-debug-sections, which requests
 105   compression of DWARF debug information sections in the relocatable output
 106   file.  Compressed debug sections are supported by readelf, objdump, and
 107   gold, but not currently by Gnu ld.
 108
 109 Changes in 2.20:
 110
 111 * Added support for v850e2 and v850e2v3.
 112
 113 * GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
 114   pseudo op.  It marks the symbol as being globally unique in the entire
 115   process.
 116
 117 * ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
 118   in binary rather than text.
 119
 120 * Add support for common symbol alignment to PE formats.
 121
 122 * Add support for the new discriminator column in the DWARF line table,
 123   with a discriminator operand for the .loc directive.
 124
 125 * Add support for Sunplus score architecture.
 126
 127 * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
 128   indicate that if the symbol is the target of a relocation, its value should
 129   not be use.  Instead the function should be invoked and its result used as
 130   the value.
 131
 132 * Add support for Lattice Mico32 (lm32) architecture.
 133
 134 * Add support for Xilinx MicroBlaze architecture.
 135
 136 Changes in 2.19:
 137
 138 * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
 139   tables without runtime relocation.
 140
 141 * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
 142   adds compatibility with H'00 style hex constants.
 143
 144 * New command line option, -msse-check=[none|error|warning], for x86
 145   targets.
 146
 147 * New sub-option added to the assembler's -a command line switch to
 148   generate a listing output.  The 'g' sub-option will insert into the listing
 149   various information about the assembly, such as assembler version, the
 150   command line options used, and a time stamp.
 151
 152 * New command line option -msse2avx for x86 target to encode SSE
 153   instructions with VEX prefix.
 154
 155 * Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
 156
 157 * New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
 158   -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
 159   -mnaked-reg and -mold-gcc, for x86 targets.
 160
 161 * Support for generating wide character strings has been added via the new
 162   pseudo ops: .string16, .string32 and .string64.
 163
 164 * Support for SSE5 has been added to the i386 port.
 165
 166 Changes in 2.18:
 167
 168 * The GAS sources are now released under the GPLv3.
 169
 170 * Support for the National Semiconductor CR16 target has been added.
 171
 172 * Added gas .reloc pseudo.  This is a low-level interface for creating
 173   relocations.
 174
 175 * Add support for x86_64 PE+ target.
 176
 177 * Add support for Score target.
 178
 179 Changes in 2.17:
 180
 181 * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
 182
 183 * Support for ms2 architecture has been added.
 184
 185 * Support for the Z80 processor family has been added.
 186
 187 * Add support for the "@<file>" syntax to the command line, so that extra
 188   switches can be read from <file>.
 189
 190 * The SH target supports a new command line switch --enable-reg-prefix which,
 191   if enabled, will allow register names to be optionally prefixed with a $
 192   character.  This allows register names to be distinguished from label names.
 193
 194 * Macros with a variable number of arguments are now supported. See the
 195   documentation for how this works.
 196
 197 * Added --reduce-memory-overheads switch to reduce the size of the hash
 198   tables used, at the expense of longer assembly times, and
 199   --hash-size=<NUMBER> to set the size of the hash tables used by gas.
 200
 201 * Macro names and macro parameter names can now be any identifier that would
 202   also be legal as a symbol elsewhere. For macro parameter names, this is
 203   known to cause problems in certain sources when the respective target uses
 204   characters inconsistently, and thus macro parameter references may no longer
 205   be recognized as such (see the documentation for details).
 206
 207 * Support the .f_floating, .d_floating, .g_floating and .h_floating directives
 208   for the VAX target in order to be more compatible with the VAX MACRO
 209   assembler.
 210
 211 * New command line option -mtune=[itanium1|itanium2] for IA64 targets.
 212
 213 Changes in 2.16:
 214
 215 * Redefinition of macros now results in an error.
 216
 217 * New command line option -mhint.b=[ok|warning|error] for IA64 targets.
 218
 219 * New command line option -munwind-check=[warning|error] for IA64
 220   targets.
 221
 222 * The IA64 port now uses automatic dependency violation removal as its default
 223   mode.
 224
 225 * Port to MAXQ processor contributed by HCL Tech.
 226
 227 * Added support for generating unwind tables for ARM ELF targets.
 228
 229 * Add a -g command line option to generate debug information in the target's
 230   preferred debug format.
 231
 232 * Support for the crx-elf target added.
 233
 234 * Support for the sh-symbianelf target added.
 235
 236 * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
 237   on pe[i]-i386; required for this target's DWARF 2 support.
 238
 239 * Support for Motorola MCF521x/5249/547x/548x added.
 240
 241 * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
 242   instrucitons.
 243
 244 * New command line option -mno-shared for MIPS ELF targets.
 245
 246 * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
 247   added to enter (and leave) alternate macro syntax mode.
 248
 249 Changes in 2.15:
 250
 251 * The MIPS -membedded-pic option (Embedded-PIC code generation) is
 252   deprecated and will be removed in a future release.
 253
 254 * Added PIC m32r Linux (ELF) and support to M32R assembler.
 255
 256 * Added support for ARM V6.
 257
 258 * Added support for sh4a and variants.
 259
 260 * Support for Renesas M32R2 added.
 261
 262 * Limited support for Mapping Symbols as specified in the ARM ELF
 263   specification has been added to the arm assembler.
 264
 265 * On ARM architectures, added a new gas directive ".unreq" that undoes
 266   definitions created by ".req".
 267
 268 * Support for Motorola ColdFire MCF528x added.
 269
 270 * Added --gstabs+ switch to enable the generation of STABS debug format
 271   information with GNU extensions.
 272
 273 * Added support for MIPS64 Release 2.
 274
 275 * Added support for v850e1.
 276
 277 * Added -n switch for x86 assembler.  By default, x86 GAS replaces
 278   multiple nop instructions used for alignment within code sections
 279   with multi-byte nop instructions such as leal 0(%esi,1),%esi.  This
 280   switch disables the optimization.
 281
 282 * Removed -n option from MIPS assembler.  It was not useful, and confused the
 283   existing -non_shared option.
 284
 285 Changes in 2.14:
 286
 287 * Added support for MIPS32 Release 2.
 288
 289 * Added support for Xtensa architecture.
 290
 291 * Support for Intel's iWMMXt processor (an ARM variant) added.
 292
 293 * An assembler test generator has been contributed and an example file that
 294   uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).
 295
 296 * Support for SH2E added.
 297
 298 * GASP has now been removed.
 299
 300 * Support for Texas Instruments TMS320C4x and TMS320C3x series of
 301   DSP's contributed by Michael Hayes and Svein E. Seldal.
 302
 303 * Support for the Ubicom IP2xxx microcontroller added.
 304
 305 Changes in 2.13:
 306
 307 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
 308   and FR500 included.
 309
 310 * Support for DLX processor added.
 311
 312 * GASP has now been deprecated and will be removed in a future release.  Use
 313   the macro facilities in GAS instead.
 314
 315 * GASP now correctly parses floating point numbers. Unless the base is
 316   explicitly specified, they are interpreted as decimal numbers regardless of
 317   the currently specified base.
 318
 319 Changes in 2.12:
 320
 321 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
 322
 323 * Support for the OpenRISC 32-bit embedded processor by OpenCores.
 324
 325 * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
 326   specifying the target instruction set.  The old method of specifying the
 327   target processor has been deprecated, but is still accepted for
 328   compatibility.
 329
 330 * Support for the VFP floating-point instruction set has been added to
 331   the ARM assembler.
 332
 333 * New psuedo op: .incbin to include a set of binary data at a given point
 334   in the assembly.  Contributed by Anders Norlander.
 335
 336 * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
 337   but still works for compatability.
 338
 339 * The MIPS assembler no longer issues a warning by default when it
 340   generates a nop instruction from a macro. The new command line option
 341   -n will turn on the warning.
 342
 343 Changes in 2.11:
 344
 345 * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
 346
 347 * x86 gas now supports the full Pentium4 instruction set.
 348
 349 * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
 350
 351 * Support for Motorola 68HC11 and 68HC12.
 352
 353 * Support for Texas Instruments TMS320C54x (tic54x).
 354
 355 * Support for IA-64.
 356
 357 * Support for i860, by Jason Eckhardt.
 358
 359 * Support for CRIS (Axis Communications ETRAX series).
 360
 361 * x86 gas has a new .arch pseudo op to specify the target CPU architecture.
 362
 363 * x86 gas -q command line option quietens warnings about register size changes
 364   due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
 365   translating various deprecated floating point instructions.
 366
 367 Changes in 2.10:
 368
 369 * Support for the ARM msr instruction was changed to only allow an immediate
 370   operand when altering the flags field.
 371
 372 * Support for ATMEL AVR.
 373
 374 * Support for IBM 370 ELF.  Somewhat experimental.
 375
 376 * Support for numbers with suffixes.
 377
 378 * Added support for breaking to the end of repeat loops.
 379
 380 * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
 381
 382 * New .elseif pseudo-op added.
 383
 384 * New --fatal-warnings option.
 385
 386 * picoJava architecture support added.
 387
 388 * Motorola MCore 210 processor support added.
 389
 390 * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
 391   assembly programs with intel syntax.
 392
 393 * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
 394
 395 * Added -gdwarf2 option to generate DWARF 2 debugging information.
 396
 397 * Full 16-bit mode support for i386.
 398
 399 * Greatly improved instruction operand checking for i386.  This change will
 400   produce errors or warnings on incorrect assembly code that previous versions
 401   of gas accepted.  If you get unexpected messages from code that worked with
 402   older versions of gas, please double check the code before reporting a bug.
 403
 404 * Weak symbol support added for COFF targets.
 405
 406 * Mitsubishi D30V support added.
 407
 408 * Texas Instruments c80 (tms320c80) support added.
 409
 410 * i960 ELF support added.
 411
 412 * ARM ELF support added.
 413
 414 Changes in 2.9:
 415
 416 * Texas Instruments c30 (tms320c30) support added.
 417
 418 * The assembler now optimizes the exception frame information generated by egcs
 419   and gcc 2.8.  The new --traditional-format option disables this optimization.
 420
 421 * Added --gstabs option to generate stabs debugging information.
 422
 423 * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
 424   listing.
 425
 426 * Added -MD option to print dependencies.
 427
 428 Changes in 2.8:
 429
 430 * BeOS support added.
 431
 432 * MIPS16 support added.
 433
 434 * Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
 435
 436 * Alpha/VMS support added.
 437
 438 * m68k options --base-size-default-16, --base-size-default-32,
 439   --disp-size-default-16, and --disp-size-default-32 added.
 440
 441 * The alignment directives now take an optional third argument, which is the
 442   maximum number of bytes to skip.  If doing the alignment would require
 443   skipping more than the given number of bytes, the alignment is not done at
 444   all.
 445
 446 * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
 447
 448 * The -a option takes a new suboption, c (e.g., -alc), to skip false
 449   conditionals in listings.
 450
 451 * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
 452   the symbol is already defined.
 453
 454 Changes in 2.7:
 455
 456 * The PowerPC assembler now allows the use of symbolic register names (r0,
 457   etc.) if -mregnames is used.  Symbolic names preceded by a '%' (%r0, etc.)
 458   can be used any time.  PowerPC 860 move to/from SPR instructions have been
 459   added.
 460
 461 * Alpha Linux (ELF) support added.
 462
 463 * PowerPC ELF support added.
 464
 465 * m68k Linux (ELF) support added.
 466
 467 * i960 Hx/Jx support added.
 468
 469 * i386/PowerPC gnu-win32 support added.
 470
 471 * SCO ELF support added.  For OpenServer 5 targets (i386-unknown-sco3.2v5) the
 472   default is to build COFF-only support.  To get a set of tools that generate
 473   ELF (they'll understand both COFF and ELF), you must configure with
 474   target=i386-unknown-sco3.2v5elf.
 475
 476 * m88k-motorola-sysv3* support added.
 477
 478 Changes in 2.6:
 479
 480 * Gas now directly supports macros, without requiring GASP.
 481
 482 * Gas now has an MRI assembler compatibility mode.  Use -M or --mri to select
 483   MRI mode.  The pseudo-op ``.mri 1'' will switch into the MRI mode until the
 484   ``.mri 0'' is seen; this can be convenient for inline assembler code.
 485
 486 * Added --defsym SYM=VALUE option.
 487
 488 * Added -mips4 support to MIPS assembler.
 489
 490 * Added PIC support to Solaris and SPARC SunOS 4 assembler.
 491
 492 Changes in 2.4:
 493
 494 * Converted this directory to use an autoconf-generated configure script.
 495
 496 * ARM support, from Richard Earnshaw.
 497
 498 * Updated VMS support, from Pat Rankin, including considerably improved
 499   debugging support.
 500
 501 * Support for the control registers in the 68060.
 502
 503 * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
 504   provide for possible future gcc changes, for targets where gas provides some
 505   features not available in the native assembler.  If the native assembler is
 506   used, it should become obvious pretty quickly what the problem is.
 507
 508 * Usage message is available with "--help".
 509
 510 * The GNU Assembler Preprocessor (gasp) is included.  (Actually, it was in 2.3
 511   also, but didn't get into the NEWS file.)
 512
 513 * Weak symbol support for a.out.
 514
 515 * A bug in the listing code which could cause an infinite loop has been fixed.
 516   Bugs in listings when generating a COFF object file have also been fixed.
 517
 518 * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
 519   Paul Kranenburg.
 520
 521 * Improved Alpha support.  Immediate constants can have a much larger range
 522   now. Support for the 21164 has been contributed by Digital.
 523
 524 * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
 525
 526 Changes in 2.3:
 527
 528 * Mach i386 support, by David Mackenzie and Ken Raeburn.
 529
 530 * RS/6000 and PowerPC support by Ian Taylor.
 531
 532 * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
 533   based on mail received from various people.  The `-h#' option should work
 534   again too.
 535
 536 * HP-PA work, by Jeff Law.  Note, for the PA, gas-2.3 has been designed to work
 537   with gdb-4.12 and gcc-2.6.  As gcc-2.6 has not been released yet, a special
 538   version of gcc-2.5.8 has been patched to work with gas-2.3.  You can retrieve
 539   this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
 540   in the "dist" directory.
 541
 542 * Vax support in gas fixed for BSD, so it builds and seems to run a couple
 543   simple tests okay.  I haven't put it through extensive testing.  (GNU make is
 544   currently required for BSD 4.3 builds.)
 545
 546 * Support for the DEC Alpha, running OSF/1 (ECOFF format).  The gas support is
 547   based on code donated by CMU, which used an a.out-based format.  I'm afraid
 548   the alpha-a.out support is pretty badly mangled, and much of it removed;
 549   making it work will require rewriting it as BFD support for the format anyways.
 550
 551 * Irix 5 support.
 552
 553 * The test suites have been fixed up a bit, so that they should work with a
 554   couple different versions of expect and dejagnu.
 555
 556 * Symbols' values are now handled internally as expressions, permitting more
 557   flexibility in evaluating them in some cases.  Some details of relocation
 558   handling have also changed, and simple constant pool management has been
 559   added, to make the Alpha port easier.
 560
 561 * New option "--statistics" for printing out program run times.  This is
 562   intended to be used with the gcc "-Q" option, which prints out times spent in
 563   various phases of compilation.  (You should be able to get all of them
 564   printed out with "gcc -Q -Wa,--statistics", I think.)
 565
 566 Changes in 2.2:
 567
 568 * RS/6000 AIX and MIPS SGI Irix 5 support has been added.
 569
 570 * Configurations that are still in development (and therefore are convenient to
 571   have listed in configure.in) still get rejected without a minor change to
 572   gas/Makefile.in, so people not doing development work shouldn't get the
 573   impression that support for such configurations is actually believed to be
 574   reliable.
 575
 576 * The program name (usually "as") is printed when a fatal error message is
 577   displayed.  This should prevent some confusion about the source of occasional
 578   messages about "internal errors".
 579
 580 * ELF support is falling into place.  Support for the 386 should be working.
 581   Support for SPARC Solaris is in.  HPPA support from Utah is being integrated.
 582
 583 * Symbol values are maintained as expressions instead of being immediately
 584   boiled down to add-symbol, sub-symbol, and constant.  This permits slightly
 585   more complex calculations involving symbols whose values are not alreadey
 586   known.
 587
 588 * DBX-style debugging info ("stabs") is now supported for COFF formats.
 589   If any stabs directives are seen in the source, GAS will create two new
 590   sections: a ".stab" and a ".stabstr" section.  The format of the .stab
 591   section is nearly identical to the a.out symbol format, and .stabstr is
 592   its string table.  For this to be useful, you must have configured GCC
 593   to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
 594   that can use the stab sections (4.11 or later).
 595
 596 * LynxOS, on i386 and m68k platforms, is now supported.  SPARC LynxOS
 597   support is in progress.
 598
 599 Changes in 2.1:
 600
 601 * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
 602   incorporated, but not well tested yet.
 603
 604 * Altered the opcode table split for m68k; it should require less VM to compile
 605   with gcc now.
 606
 607 * Some minor adjustments to add (Convergent Technologies') Miniframe support,
 608   suggested by Ronald Cole.
 609
 610 * HPPA support (running OSF only, not HPUX) has been contributed by Utah.  This
 611   includes improved ELF support, which I've started adapting for SPARC Solaris
 612   2.x.  Integration isn't completely, so it probably won't work.
 613
 614 * HP9000/300 support, donated by HP, has been merged in.
 615
 616 * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
 617
 618 * Better error messages for unsupported configurations (e.g., hppa-hpux).
 619
 620 * Test suite framework is starting to become reasonable.
 621
 622 Changes in 2.0:
 623
 624 * Mostly bug fixes.
 625
 626 * Some more merging of BFD and ELF code, but ELF still doesn't work.
 627
 628 Changes in 1.94:
 629
 630 * BFD merge is partly done.  Adventurous souls may try giving configure the
 631   "--with-bfd-assembler" option.  Currently, ELF format requires it, a.out
 632   format accepts it; SPARC CPU accepts it.  It's the default only for OS "elf"
 633   or "solaris".  (ELF isn't really supported yet.  It needs work.  I've got
 634   some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
 635   fully merged yet.)
 636
 637 * The 68K opcode table has been split in half.  It should now compile under gcc
 638   without consuming ridiculous amounts of memory.
 639
 640 * A couple data structures have been reduced in size.  This should result in
 641   saving a little bit of space at runtime.
 642
 643 * Support for MIPS, from OSF and Ralph Campbell, has been merged in.  The OSF
 644   code provided ROSE format support, which I haven't merged in yet.  (I can
 645   make it available, if anyone wants to try it out.)  Ralph's code, for BSD
 646   4.4, supports a.out format.  We don't have ECOFF support in just yet; it's
 647   coming.
 648
 649 * Support for the Hitachi H8/500 has been added.
 650
 651 * VMS host and target support should be working now, thanks chiefly to Eric
 652   Youngdale.
 653
 654 Changes in 1.93.01:
 655
 656 * For m68k, support for more processors has been added: 68040, CPU32, 68851.
 657
 658 * For i386, .align is now power-of-two; was number-of-bytes.
 659
 660 * For m68k, "%" is now accepted before register names.  For COFF format, which
 661   doesn't use underscore prefixes for C labels, it is required, so variable "a0"
 662   can be distinguished from the register.
 663
 664 * Last public release was 1.38.  Lots of configuration changes since then, lots
 665   of new CPUs and formats, lots of bugs fixed.
