5e75c3ab
JB
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).

8ad30312
NC
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
78849248

312* The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
313 specifying the target instruction set. The old method of specifying the
a40cbfa3
NC
314 target processor has been deprecated, but is still accepted for
315 compatibility.
03b1477f 316
a40cbfa3
NC

a40cbfa3 423* Alpha/VMS support added.
252b5132 424
a40cbfa3
NC
425* m68k options --base-size-default-16, --base-size-default-32,
426 --disp-size-default-16, and --disp-size-default-32 added.
252b5132 427
a40cbfa3
NC
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.
252b5132 432
a40cbfa3 433* The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
252b5132 434
a40cbfa3
NC
435* The -a option takes a new suboption, c (e.g., -alc), to skip false
436 conditionals in listings.
252b5132 437
a40cbfa3
NC
438* Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
439 the symbol is already defined.
252b5132
RH
440
441Changes in 2.7:
442
a40cbfa3
NC
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.
252b5132 447
a40cbfa3 448* Alpha Linux (ELF) support added.
252b5132 449
a40cbfa3 450* PowerPC ELF support added.
252b5132 451
a40cbfa3 452* m68k Linux (ELF) support added.
252b5132 453
a40cbfa3 454* i960 Hx/Jx support added.
252b5132 455
a40cbfa3 456* i386/PowerPC gnu-win32 support added.
252b5132 457
a40cbfa3
NC
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
fa94de6b 460 ELF (they'll understand both COFF and ELF), you must configure with
a40cbfa3 461 target=i386-unknown-sco3.2v5elf.
252b5132 462
a40cbfa3 463* m88k-motorola-sysv3* support added.
252b5132
RH
464
465Changes in 2.6:
466
a40cbfa3 467* Gas now directly supports macros, without requiring GASP.
252b5132 468
a40cbfa3
NC
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.
252b5132 472
a40cbfa3 473* Added --defsym SYM=VALUE option.
252b5132 474
a40cbfa3 475* Added -mips4 support to MIPS assembler.
252b5132 476
a40cbfa3 477* Added PIC support to Solaris and SPARC SunOS 4 assembler.
252b5132
RH
478
479Changes in 2.4:
480
a40cbfa3 481* Converted this directory to use an autoconf-generated configure script.
252b5132 482
a40cbfa3 483* ARM support, from Richard Earnshaw.
252b5132 484
a40cbfa3
NC
485* Updated VMS support, from Pat Rankin, including considerably improved
486 debugging support.
252b5132 487
a40cbfa3 488* Support for the control registers in the 68060.
252b5132 489
a40cbfa3 490* Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
fa94de6b
RM
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
a40cbfa3 493 used, it should become obvious pretty quickly what the problem is.
252b5132 494
a40cbfa3 495* Usage message is available with "--help".
252b5132 496
fa94de6b 497* The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3
a40cbfa3 498 also, but didn't get into the NEWS file.)
252b5132 499
a40cbfa3 500* Weak symbol support for a.out.
252b5132 501
fa94de6b 502* A bug in the listing code which could cause an infinite loop has been fixed.
a40cbfa3 503 Bugs in listings when generating a COFF object file have also been fixed.
252b5132 504
a40cbfa3
NC
505* Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
506 Paul Kranenburg.
252b5132 507
a40cbfa3
NC
508* Improved Alpha support. Immediate constants can have a much larger range
509 now. Support for the 21164 has been contributed by Digital.
252b5132 510
a40cbfa3 511* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
252b5132
RH
512
513Changes in 2.3:
514
a40cbfa3 515* Mach i386 support, by David Mackenzie and Ken Raeburn.
252b5132 516
a40cbfa3 517* RS/6000 and PowerPC support by Ian Taylor.
252b5132 518
a40cbfa3
NC
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.
252b5132 522
a40cbfa3 523* HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work
fa94de6b 524 with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special
a40cbfa3
NC
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.
252b5132 528
a40cbfa3
NC
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.)
252b5132 532
fa94de6b 533* Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is
a40cbfa3
NC
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.
252b5132 537
a40cbfa3 538* Irix 5 support.
252b5132 539
fa94de6b 540* The test suites have been fixed up a bit, so that they should work with a
a40cbfa3 541 couple different versions of expect and dejagnu.
252b5132 542
fa94de6b
RM
543* Symbols' values are now handled internally as expressions, permitting more
544 flexibility in evaluating them in some cases. Some details of relocation
a40cbfa3
NC
545 handling have also changed, and simple constant pool management has been
546 added, to make the Alpha port easier.
252b5132 547
a40cbfa3
NC
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.)
252b5132
RH
552
553Changes in 2.2:
554
a40cbfa3 555* RS/6000 AIX and MIPS SGI Irix 5 support has been added.
252b5132 556
fa94de6b
RM
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
a40cbfa3
NC
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.
252b5132 562
fa94de6b 563* The program name (usually "as") is printed when a fatal error message is
a40cbfa3
NC
564 displayed. This should prevent some confusion about the source of occasional
565 messages about "internal errors".
252b5132 566
fa94de6b 567* ELF support is falling into place. Support for the 386 should be working.
a40cbfa3 568 Support for SPARC Solaris is in. HPPA support from Utah is being integrated.
252b5132 569
a40cbfa3
NC
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.
252b5132 574
a40cbfa3 575* DBX-style debugging info ("stabs") is now supported for COFF formats.
fa94de6b
RM
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
a40cbfa3
NC
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).
252b5132 582
fa94de6b 583* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS
a40cbfa3 584 support is in progress.
252b5132
RH
585
586Changes in 2.1:
587
fa94de6b 588* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
a40cbfa3 589 incorporated, but not well tested yet.
252b5132 590
fa94de6b 591* Altered the opcode table split for m68k; it should require less VM to compile
a40cbfa3 592 with gcc now.
252b5132 593
a40cbfa3
NC
594* Some minor adjustments to add (Convergent Technologies') Miniframe support,
595 suggested by Ronald Cole.
252b5132 596
a40cbfa3
NC
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.
252b5132 600
a40cbfa3 601* HP9000/300 support, donated by HP, has been merged in.
252b5132 602
a40cbfa3 603* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
252b5132 604
a40cbfa3 605* Better error messages for unsupported configurations (e.g., hppa-hpux).
252b5132 606
a40cbfa3 607* Test suite framework is starting to become reasonable.
252b5132
RH
608
609Changes in 2.0:
610
a40cbfa3 611* Mostly bug fixes.
252b5132 612
a40cbfa3 613* Some more merging of BFD and ELF code, but ELF still doesn't work.
252b5132
RH
614
615Changes in 1.94:
616
a40cbfa3
NC
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.)
252b5132 623
a40cbfa3
NC
624* The 68K opcode table has been split in half. It should now compile under gcc
625 without consuming ridiculous amounts of memory.
252b5132 626
a40cbfa3
NC
627* A couple data structures have been reduced in size. This should result in
628 saving a little bit of space at runtime.
252b5132 629
a40cbfa3
NC
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.
252b5132 635
a40cbfa3 636* Support for the Hitachi H8/500 has been added.
252b5132 637
a40cbfa3
NC
638* VMS host and target support should be working now, thanks chiefly to Eric
639 Youngdale.
252b5132
RH
640
641Changes in 1.93.01:
642
a40cbfa3 643* For m68k, support for more processors has been added: 68040, CPU32, 68851.
252b5132 644
a40cbfa3 645* For i386, .align is now power-of-two; was number-of-bytes.
252b5132 646
a40cbfa3
NC
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.
252b5132 650
a40cbfa3
NC
651* Last public release was 1.38. Lots of configuration changes since then, lots
652 of new CPUs and formats, lots of bugs fixed.
