5e75c3ab
JB
181* Macro names and macro parameter names can now be any identifier that would
182 also be legal as a symbol elsewhere. For macro parameter names, this is
183 known to cause problems in certain sources when the respective target uses
184 characters inconsistently, and thus macro parameter references may no longer
185 be recognized as such (see the documentation for details).

257* Added -n switch for x86 assembler. By default, x86 GAS replaces
258 multiple nop instructions used for alignment within code sections
259 with multi-byte nop instructions such as leal 0(%esi,1),%esi. This
260 switch disables the optimization.
261
78849248

305* The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
306 specifying the target instruction set. The old method of specifying the
a40cbfa3
NC
307 target processor has been deprecated, but is still accepted for
308 compatibility.
03b1477f 309
a40cbfa3
NC

NC
421* The alignment directives now take an optional third argument, which is the
422 maximum number of bytes to skip. If doing the alignment would require
423 skipping more than the given number of bytes, the alignment is not done at
424 all.
252b5132 425
a40cbfa3 426* The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
252b5132 427
a40cbfa3
NC
428* The -a option takes a new suboption, c (e.g., -alc), to skip false
429 conditionals in listings.
252b5132 430
a40cbfa3
NC
431* Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
432 the symbol is already defined.
252b5132
RH
433
434Changes in 2.7:
435
a40cbfa3
NC
436* The PowerPC assembler now allows the use of symbolic register names (r0,
437 etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.)
438 can be used any time. PowerPC 860 move to/from SPR instructions have been
439 added.
252b5132 440
a40cbfa3 441* Alpha Linux (ELF) support added.
252b5132 442
a40cbfa3 443* PowerPC ELF support added.
252b5132 444
a40cbfa3 445* m68k Linux (ELF) support added.
252b5132 446
a40cbfa3 447* i960 Hx/Jx support added.
252b5132 448
a40cbfa3 449* i386/PowerPC gnu-win32 support added.
252b5132 450
a40cbfa3
NC
451* SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the
452 default is to build COFF-only support. To get a set of tools that generate
fa94de6b 453 ELF (they'll understand both COFF and ELF), you must configure with
a40cbfa3 454 target=i386-unknown-sco3.2v5elf.
252b5132 455
a40cbfa3 456* m88k-motorola-sysv3* support added.
252b5132
RH
457
458Changes in 2.6:
459
a40cbfa3 460* Gas now directly supports macros, without requiring GASP.
252b5132 461
a40cbfa3
NC
462* Gas now has an MRI assembler compatibility mode. Use -M or --mri to select
463 MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the
464 ``.mri 0'' is seen; this can be convenient for inline assembler code.
252b5132 465
a40cbfa3 466* Added --defsym SYM=VALUE option.
252b5132 467
a40cbfa3 468* Added -mips4 support to MIPS assembler.
252b5132 469
a40cbfa3 470* Added PIC support to Solaris and SPARC SunOS 4 assembler.
252b5132
RH
471
472Changes in 2.4:
473
a40cbfa3 474* Converted this directory to use an autoconf-generated configure script.
252b5132 475
a40cbfa3 476* ARM support, from Richard Earnshaw.
252b5132 477
a40cbfa3
NC
478* Updated VMS support, from Pat Rankin, including considerably improved
479 debugging support.
252b5132 480
a40cbfa3 481* Support for the control registers in the 68060.
252b5132 482
a40cbfa3 483* Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
fa94de6b
RM
484 provide for possible future gcc changes, for targets where gas provides some
485 features not available in the native assembler. If the native assembler is
a40cbfa3 486 used, it should become obvious pretty quickly what the problem is.
252b5132 487
a40cbfa3 488* Usage message is available with "--help".
252b5132 489
fa94de6b 490* The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3
a40cbfa3 491 also, but didn't get into the NEWS file.)
252b5132 492
a40cbfa3 493* Weak symbol support for a.out.
252b5132 494
fa94de6b 495* A bug in the listing code which could cause an infinite loop has been fixed.
a40cbfa3 496 Bugs in listings when generating a COFF object file have also been fixed.
252b5132 497
a40cbfa3
NC
498* Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
499 Paul Kranenburg.
252b5132 500
a40cbfa3
NC
501* Improved Alpha support. Immediate constants can have a much larger range
502 now. Support for the 21164 has been contributed by Digital.
252b5132 503
a40cbfa3 504* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
252b5132
RH
505
506Changes in 2.3:
507
a40cbfa3 508* Mach i386 support, by David Mackenzie and Ken Raeburn.
252b5132 509
a40cbfa3 510* RS/6000 and PowerPC support by Ian Taylor.
252b5132 511
a40cbfa3
NC
512* VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
513 based on mail received from various people. The `-h#' option should work
514 again too.
252b5132 515
a40cbfa3 516* HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work
fa94de6b 517 with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special
a40cbfa3
NC
518 version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve
519 this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
520 in the "dist" directory.
252b5132 521
a40cbfa3
NC
522* Vax support in gas fixed for BSD, so it builds and seems to run a couple
523 simple tests okay. I haven't put it through extensive testing. (GNU make is
524 currently required for BSD 4.3 builds.)
252b5132 525
fa94de6b 526* Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is
a40cbfa3
NC
527 based on code donated by CMU, which used an a.out-based format. I'm afraid
528 the alpha-a.out support is pretty badly mangled, and much of it removed;
529 making it work will require rewriting it as BFD support for the format anyways.
252b5132 530
a40cbfa3 531* Irix 5 support.
252b5132 532
fa94de6b 533* The test suites have been fixed up a bit, so that they should work with a
a40cbfa3 534 couple different versions of expect and dejagnu.
252b5132 535
fa94de6b
RM
536* Symbols' values are now handled internally as expressions, permitting more
537 flexibility in evaluating them in some cases. Some details of relocation
a40cbfa3
NC
538 handling have also changed, and simple constant pool management has been
539 added, to make the Alpha port easier.
252b5132 540
a40cbfa3
NC
541* New option "--statistics" for printing out program run times. This is
542 intended to be used with the gcc "-Q" option, which prints out times spent in
543 various phases of compilation. (You should be able to get all of them
544 printed out with "gcc -Q -Wa,--statistics", I think.)
252b5132
RH
545
546Changes in 2.2:
547
a40cbfa3 548* RS/6000 AIX and MIPS SGI Irix 5 support has been added.
252b5132 549
fa94de6b
RM
550* Configurations that are still in development (and therefore are convenient to
551 have listed in configure.in) still get rejected without a minor change to
a40cbfa3
NC
552 gas/Makefile.in, so people not doing development work shouldn't get the
553 impression that support for such configurations is actually believed to be
554 reliable.
252b5132 555
fa94de6b 556* The program name (usually "as") is printed when a fatal error message is
a40cbfa3
NC
557 displayed. This should prevent some confusion about the source of occasional
558 messages about "internal errors".
252b5132 559
fa94de6b 560* ELF support is falling into place. Support for the 386 should be working.
a40cbfa3 561 Support for SPARC Solaris is in. HPPA support from Utah is being integrated.
252b5132 562
a40cbfa3
NC
563* Symbol values are maintained as expressions instead of being immediately
564 boiled down to add-symbol, sub-symbol, and constant. This permits slightly
565 more complex calculations involving symbols whose values are not alreadey
566 known.
252b5132 567
a40cbfa3 568* DBX-style debugging info ("stabs") is now supported for COFF formats.
fa94de6b
RM
569 If any stabs directives are seen in the source, GAS will create two new
570 sections: a ".stab" and a ".stabstr" section. The format of the .stab
a40cbfa3
NC
571 section is nearly identical to the a.out symbol format, and .stabstr is
572 its string table. For this to be useful, you must have configured GCC
573 to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
574 that can use the stab sections (4.11 or later).
252b5132 575
fa94de6b 576* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS
a40cbfa3 577 support is in progress.
252b5132
RH
578
579Changes in 2.1:
580
fa94de6b 581* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
a40cbfa3 582 incorporated, but not well tested yet.
252b5132 583
fa94de6b 584* Altered the opcode table split for m68k; it should require less VM to compile
a40cbfa3 585 with gcc now.
252b5132 586
a40cbfa3
NC
587* Some minor adjustments to add (Convergent Technologies') Miniframe support,
588 suggested by Ronald Cole.
252b5132 589
a40cbfa3
NC
590* HPPA support (running OSF only, not HPUX) has been contributed by Utah. This
591 includes improved ELF support, which I've started adapting for SPARC Solaris
592 2.x. Integration isn't completely, so it probably won't work.
252b5132 593
a40cbfa3 594* HP9000/300 support, donated by HP, has been merged in.
252b5132 595
a40cbfa3 596* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
252b5132 597
a40cbfa3 598* Better error messages for unsupported configurations (e.g., hppa-hpux).
252b5132 599
a40cbfa3 600* Test suite framework is starting to become reasonable.
252b5132
RH
601
602Changes in 2.0:
603
a40cbfa3 604* Mostly bug fixes.
252b5132 605
a40cbfa3 606* Some more merging of BFD and ELF code, but ELF still doesn't work.
252b5132
RH
607
608Changes in 1.94:
609
a40cbfa3
NC
610* BFD merge is partly done. Adventurous souls may try giving configure the
611 "--with-bfd-assembler" option. Currently, ELF format requires it, a.out
612 format accepts it; SPARC CPU accepts it. It's the default only for OS "elf"
613 or "solaris". (ELF isn't really supported yet. It needs work. I've got
614 some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
615 fully merged yet.)
252b5132 616
a40cbfa3
NC
617* The 68K opcode table has been split in half. It should now compile under gcc
618 without consuming ridiculous amounts of memory.
252b5132 619
a40cbfa3
NC
620* A couple data structures have been reduced in size. This should result in
621 saving a little bit of space at runtime.
252b5132 622
a40cbfa3
NC
623* Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF
624 code provided ROSE format support, which I haven't merged in yet. (I can
625 make it available, if anyone wants to try it out.) Ralph's code, for BSD
626 4.4, supports a.out format. We don't have ECOFF support in just yet; it's
627 coming.
252b5132 628
a40cbfa3 629* Support for the Hitachi H8/500 has been added.
252b5132 630
a40cbfa3
NC
631* VMS host and target support should be working now, thanks chiefly to Eric
632 Youngdale.
252b5132
RH
633
634Changes in 1.93.01:
635
a40cbfa3 636* For m68k, support for more processors has been added: 68040, CPU32, 68851.
252b5132 637
a40cbfa3 638* For i386, .align is now power-of-two; was number-of-bytes.
252b5132 639
a40cbfa3
NC
640* For m68k, "%" is now accepted before register names. For COFF format, which
641 doesn't use underscore prefixes for C labels, it is required, so variable "a0"
642 can be distinguished from the register.
252b5132 643
a40cbfa3
NC
644* Last public release was 1.38. Lots of configuration changes since then, lots
645 of new CPUs and formats, lots of bugs fixed.
