a05a5b64 | 375 | command-line options used, and a time stamp. |
83f10cb2 | 376 | |
a05a5b64 | 377 | * New command-line option -msse2avx for x86 target to encode SSE |
c0f3af97 L |

c0f3af97 | 381 | |
a05a5b64 | 382 | * New command-line options, -march=CPU[,+EXTENSION...], -mtune=CPU, |
ae40c993 L |
383 | -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg, |
384 | -mnaked-reg and -mold-gcc, for x86 targets. | |
385 | ||
38a57ae7 NC |
386 | * Support for generating wide character strings has been added via the new |
387 | pseudo ops: .string16, .string32 and .string64. | |
388 | ||
85f10a01 MM |
389 | * Support for SSE5 has been added to the i386 port. |
390 | ||
7c3d153f NC |
391 | Changes in 2.18: |
392 | ||
ec2655a6 NC |
393 | * The GAS sources are now released under the GPLv3. |
394 | ||
3d3d428f NC |
395 | * Support for the National Semiconductor CR16 target has been added. |
396 | ||
3f9ce309 AM |

398 | relocations. | |
399 | ||
99ad8390 NC |
400 | * Add support for x86_64 PE+ target. |
401 | ||

83518699 | 403 | |
ec2655a6 NC |
404 | Changes in 2.17: |
405 | ||
d70c5fc7 NC |
406 | * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems. |
407 | ||
08333dc4 NS |
408 | * Support for ms2 architecture has been added. |
409 | ||
b7b8fb1d NC |
410 | * Support for the Z80 processor family has been added. |
411 | ||
3e8a519c MM |
412 | * Add support for the "@<file>" syntax to the command line, so that extra |
413 | switches can be read from <file>. | |
414 | ||
a05a5b64 | 415 | * The SH target supports a new command-line switch --enable-reg-prefix which, |
37dedf66 NC |
416 | if enabled, will allow register names to be optionally prefixed with a $ |
417 | character. This allows register names to be distinguished from label names. | |
fa94de6b | 418 | |
6eaeac8a JB |
419 | * Macros with a variable number of arguments are now supported. See the |
420 | documentation for how this works. | |
421 | ||
4bdd3565 NC |
422 | * Added --reduce-memory-overheads switch to reduce the size of the hash |
423 | tables used, at the expense of longer assembly times, and | |
424 | --hash-size=<NUMBER> to set the size of the hash tables used by gas. | |
425 | ||
5e75c3ab JB |
426 | * Macro names and macro parameter names can now be any identifier that would |
427 | also be legal as a symbol elsewhere. For macro parameter names, this is | |
428 | known to cause problems in certain sources when the respective target uses | |
429 | characters inconsistently, and thus macro parameter references may no longer | |
430 | be recognized as such (see the documentation for details). | |
fa94de6b | 431 | |
d2c5f73e NC |
432 | * Support the .f_floating, .d_floating, .g_floating and .h_floating directives |
433 | for the VAX target in order to be more compatible with the VAX MACRO | |
434 | assembler. | |
435 | ||
a05a5b64 | 436 | * New command-line option -mtune=[itanium1|itanium2] for IA64 targets. |

91d777ee | 443 | |
a05a5b64 | 444 | * New command-line option -munwind-check=[warning|error] for IA64 |
970d6792 L |
445 | targets. |
446 | ||
f1dab70d JB |
447 | * The IA64 port now uses automatic dependency violation removal as its default |
448 | mode. | |
449 | ||
7499d566 NC |
450 | * Port to MAXQ processor contributed by HCL Tech. |
451 | ||
7ed4c4c5 NC |

329e276d NC |
455 | preferred debug format. |
456 | ||
1fe1f39c NC |
457 | * Support for the crx-elf target added. |
458 | ||
1a320fbb | 459 | * Support for the sh-symbianelf target added. |
1fe1f39c | 460 | |
0503b355 BF |
461 | * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations |
462 | on pe[i]-i386; required for this target's DWARF 2 support. | |
463 | ||
6b6e92f4 NC |
464 | * Support for Motorola MCF521x/5249/547x/548x added. |
465 | ||
fd99574b NC |
466 | * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC |
467 | instrucitons. | |
468 | ||
a05a5b64 | 469 | * New command-line option -mno-shared for MIPS ELF targets. |
aa6975fb | 470 | |
a05a5b64 | 471 | * New command-line option --alternate and pseudo-ops .altmacro and .noaltmacro |
caa32fe5 NC |
472 | added to enter (and leave) alternate macro syntax mode. |
473 | ||
0477af35 NC |
474 | Changes in 2.15: |
475 | ||
7a7f4e42 CD |
476 | * The MIPS -membedded-pic option (Embedded-PIC code generation) is |
477 | deprecated and will be removed in a future release. | |
478 | ||
6edf0760 NC |
479 | * Added PIC m32r Linux (ELF) and support to M32R assembler. |
480 | ||
09d92015 MM |
481 | * Added support for ARM V6. |
482 | ||
88da98f3 MS |
483 | * Added support for sh4a and variants. |
484 | ||
eb764db8 NC |
485 | * Support for Renesas M32R2 added. |
486 | ||
88da98f3 MS |
487 | * Limited support for Mapping Symbols as specified in the ARM ELF |
488 | specification has been added to the arm assembler. | |
ed769ec1 | 489 | |
0bbf2aa4 NC |
490 | * On ARM architectures, added a new gas directive ".unreq" that undoes |
491 | definitions created by ".req". | |
492 | ||
3e602632 NC |
493 | * Support for Motorola ColdFire MCF528x added. |
494 | ||
05da4302 NC |
495 | * Added --gstabs+ switch to enable the generation of STABS debug format |
496 | information with GNU extensions. | |
fa94de6b | 497 | |
6a265366 CD |
498 | * Added support for MIPS64 Release 2. |
499 | ||
8ad30312 NC |
500 | * Added support for v850e1. |
501 | ||
12b55ccc L |
502 | * Added -n switch for x86 assembler. By default, x86 GAS replaces |
503 | multiple nop instructions used for alignment within code sections | |
504 | with multi-byte nop instructions such as leal 0(%esi,1),%esi. This | |
505 | switch disables the optimization. | |
506 | ||
78849248 ILT |
507 | * Removed -n option from MIPS assembler. It was not useful, and confused the |
508 | existing -non_shared option. | |
509 | ||
43c58ae6 CD |
510 | Changes in 2.14: |
511 | ||
69be0a2b CD |
512 | * Added support for MIPS32 Release 2. |
513 | ||
e8fd7476 NC |
514 | * Added support for Xtensa architecture. |

516 | * Support for Intel's iWMMXt processor (an ARM variant) added. |
517 | ||
cce4814f NC |
518 | * An assembler test generator has been contributed and an example file that |
519 | uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c). | |
fa94de6b | 520 | |
5177500f NC |
521 | * Support for SH2E added. |
522 | ||
fea17916 NC |
523 | * GASP has now been removed. |
524 | ||
004d9caf NC |
525 | * Support for Texas Instruments TMS320C4x and TMS320C3x series of |
526 | DSP's contributed by Michael Hayes and Svein E. Seldal. | |

a40cbfa3 NC |
528 | * Support for the Ubicom IP2xxx microcontroller added. |
529 | ||
2cbb2eef NC |
530 | Changes in 2.13: |
531 | ||
a40cbfa3 NC |
532 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 |
533 | and FR500 included. | |
0ebb9a87 | 534 | |
a40cbfa3 | 535 | * Support for DLX processor added. |
52216602 | 536 | |
a40cbfa3 NC |
537 | * GASP has now been deprecated and will be removed in a future release. Use |
538 | the macro facilities in GAS instead. | |
3f965e60 | 539 | |
a40cbfa3 NC |
540 | * GASP now correctly parses floating point numbers. Unless the base is |
541 | explicitly specified, they are interpreted as decimal numbers regardless of | |
542 | the currently specified base. | |
1ac57253 | 543 | |
9a66911f NC |
544 | Changes in 2.12: |
545 | ||
a40cbfa3 | 546 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
49fda6c8 | 547 | |
a40cbfa3 | 548 | * Support for the OpenRISC 32-bit embedded processor by OpenCores. |
3b16e843 | 549 | |
fa94de6b RM |
550 | * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for |
551 | specifying the target instruction set. The old method of specifying the | |
a40cbfa3 NC |
552 | target processor has been deprecated, but is still accepted for |
553 | compatibility. | |
03b1477f | 554 | |
a40cbfa3 NC |
555 | * Support for the VFP floating-point instruction set has been added to |
556 | the ARM assembler. | |
252b5132 | 557 | |
a40cbfa3 NC |
558 | * New psuedo op: .incbin to include a set of binary data at a given point |
559 | in the assembly. Contributed by Anders Norlander. | |
7e005732 | 560 | |
a40cbfa3 NC |
561 | * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated |
562 | but still works for compatability. | |
ec68c924 | 563 | |
fa94de6b | 564 | * The MIPS assembler no longer issues a warning by default when it |
a05a5b64 | 565 | generates a nop instruction from a macro. The new command-line option |
a40cbfa3 | 566 | -n will turn on the warning. |
63486801 | 567 | |
2dac7317 JW |
568 | Changes in 2.11: |
569 | ||
500800ca NC |
570 | * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff. |
571 | ||
a40cbfa3 | 572 | * x86 gas now supports the full Pentium4 instruction set. |

a40cbfa3 | 582 | * Support for i860, by Jason Eckhardt. |
22b36938 | 583 | |
a40cbfa3 | 584 | * Support for CRIS (Axis Communications ETRAX series). |
5bcac8a4 | 585 | |
a40cbfa3 | 586 | * x86 gas has a new .arch pseudo op to specify the target CPU architecture. |
a38cf1db | 587 | |
a05a5b64 | 588 | * x86 gas -q command-line option quietens warnings about register size changes |
a40cbfa3 NC |
589 | due to suffix, indirect jmp/call without `*', stand-alone prefixes, and |
590 | translating various deprecated floating point instructions. | |
a38cf1db | 591 | |
252b5132 RH |
592 | Changes in 2.10: |
593 | ||
a40cbfa3 NC |
594 | * Support for the ARM msr instruction was changed to only allow an immediate |
595 | operand when altering the flags field. | |
d14442f4 | 596 | |
a40cbfa3 | 597 | * Support for ATMEL AVR. |
adde6300 | 598 | |
a40cbfa3 | 599 | * Support for IBM 370 ELF. Somewhat experimental. |
b5ebe70e | 600 | |
a40cbfa3 | 601 | * Support for numbers with suffixes. |
3fd9f047 | 602 | |
a40cbfa3 | 603 | * Added support for breaking to the end of repeat loops. |
6a6987a9 | 604 | |
a40cbfa3 | 605 | * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL). |
6a6987a9 | 606 | |
a40cbfa3 | 607 | * New .elseif pseudo-op added. |
3fd9f047 | 608 | |
a40cbfa3 | 609 | * New --fatal-warnings option. |
1f776aa5 | 610 | |
a40cbfa3 | 611 | * picoJava architecture support added. |
252b5132 | 612 | |
a40cbfa3 | 613 | * Motorola MCore 210 processor support added. |
041dd5a9 | 614 | |
fa94de6b | 615 | * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386 |
a40cbfa3 | 616 | assembly programs with intel syntax. |
252b5132 | 617 | |
a40cbfa3 | 618 | * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. |
252b5132 | 619 | |
a40cbfa3 | 620 | * Added -gdwarf2 option to generate DWARF 2 debugging information. |
041dd5a9 | 621 | |
a40cbfa3 | 622 | * Full 16-bit mode support for i386. |
252b5132 | 623 | |
fa94de6b | 624 | * Greatly improved instruction operand checking for i386. This change will |
a40cbfa3 NC |
625 | produce errors or warnings on incorrect assembly code that previous versions |
626 | of gas accepted. If you get unexpected messages from code that worked with | |
627 | older versions of gas, please double check the code before reporting a bug. | |
252b5132 | 628 | |
a40cbfa3 | 629 | * Weak symbol support added for COFF targets. |
252b5132 | 630 | |
a40cbfa3 | 631 | * Mitsubishi D30V support added. |
252b5132 | 632 | |
a40cbfa3 | 633 | * Texas Instruments c80 (tms320c80) support added. |
252b5132 | 634 | |
a40cbfa3 | 635 | * i960 ELF support added. |
bedf545c | 636 | |
a40cbfa3 | 637 | * ARM ELF support added. |
a057431b | 638 | |
252b5132 RH |
639 | Changes in 2.9: |
640 | ||
a40cbfa3 | 641 | * Texas Instruments c30 (tms320c30) support added. |
252b5132 | 642 | |
fa94de6b | 643 | * The assembler now optimizes the exception frame information generated by egcs |
a40cbfa3 | 644 | and gcc 2.8. The new --traditional-format option disables this optimization. |
252b5132 | 645 | |
a40cbfa3 | 646 | * Added --gstabs option to generate stabs debugging information. |
252b5132 | 647 | |
fa94de6b | 648 | * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a |
a40cbfa3 | 649 | listing. |
252b5132 | 650 | |
a40cbfa3 | 651 | * Added -MD option to print dependencies. |
252b5132 RH |
652 | |
653 | Changes in 2.8: | |
654 | ||
a40cbfa3 | 655 | * BeOS support added. |
252b5132 | 656 | |
a40cbfa3 | 657 | * MIPS16 support added. |
252b5132 | 658 | |
a40cbfa3 | 659 | * Motorola ColdFire 5200 support added (configure for m68k and use -m5200). |
252b5132 | 660 | |
a40cbfa3 | 661 | * Alpha/VMS support added. |
252b5132 | 662 | |
a40cbfa3 NC |
663 | * m68k options --base-size-default-16, --base-size-default-32, |
664 | --disp-size-default-16, and --disp-size-default-32 added. | |
252b5132 | 665 | |
a40cbfa3 NC |
666 | * The alignment directives now take an optional third argument, which is the |
667 | maximum number of bytes to skip. If doing the alignment would require | |
668 | skipping more than the given number of bytes, the alignment is not done at | |
669 | all. | |
252b5132 | 670 | |
a40cbfa3 | 671 | * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. |
252b5132 | 672 | |
a40cbfa3 NC |
673 | * The -a option takes a new suboption, c (e.g., -alc), to skip false |
674 | conditionals in listings. | |
252b5132 | 675 | |
a40cbfa3 NC |
676 | * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if |
677 | the symbol is already defined. | |
252b5132 RH |
678 | |
679 | Changes in 2.7: | |
680 | ||
a40cbfa3 NC |
681 | * The PowerPC assembler now allows the use of symbolic register names (r0, |
682 | etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) | |
683 | can be used any time. PowerPC 860 move to/from SPR instructions have been | |
684 | added. | |
252b5132 | 685 | |
a40cbfa3 | 686 | * Alpha Linux (ELF) support added. |
252b5132 | 687 | |
a40cbfa3 | 688 | * PowerPC ELF support added. |
252b5132 | 689 | |
a40cbfa3 | 690 | * m68k Linux (ELF) support added. |
252b5132 | 691 | |
a40cbfa3 | 692 | * i960 Hx/Jx support added. |
252b5132 | 693 | |
a40cbfa3 | 694 | * i386/PowerPC gnu-win32 support added. |
252b5132 | 695 | |
a40cbfa3 NC |
696 | * SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the |
697 | default is to build COFF-only support. To get a set of tools that generate | |
fa94de6b | 698 | ELF (they'll understand both COFF and ELF), you must configure with |
a40cbfa3 | 699 | target=i386-unknown-sco3.2v5elf. |
252b5132 | 700 | |
a40cbfa3 | 701 | * m88k-motorola-sysv3* support added. |
252b5132 RH |
702 | |
703 | Changes in 2.6: | |
704 | ||
a40cbfa3 | 705 | * Gas now directly supports macros, without requiring GASP. |
252b5132 | 706 | |
a40cbfa3 NC |
707 | * Gas now has an MRI assembler compatibility mode. Use -M or --mri to select |
708 | MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the | |
709 | ``.mri 0'' is seen; this can be convenient for inline assembler code. | |
252b5132 | 710 | |
a40cbfa3 | 711 | * Added --defsym SYM=VALUE option. |
252b5132 | 712 | |
a40cbfa3 | 713 | * Added -mips4 support to MIPS assembler. |
252b5132 | 714 | |
a40cbfa3 | 715 | * Added PIC support to Solaris and SPARC SunOS 4 assembler. |
252b5132 RH |
716 | |
717 | Changes in 2.4: | |
718 | ||
a40cbfa3 | 719 | * Converted this directory to use an autoconf-generated configure script. |

a40cbfa3 | 721 | * ARM support, from Richard Earnshaw. |
252b5132 | 722 | |
a40cbfa3 NC |
723 | * Updated VMS support, from Pat Rankin, including considerably improved |
724 | debugging support. | |
252b5132 | 725 | |
a40cbfa3 | 726 | * Support for the control registers in the 68060. |
252b5132 | 727 | |
a40cbfa3 | 728 | * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to |
fa94de6b RM |
729 | provide for possible future gcc changes, for targets where gas provides some |
730 | features not available in the native assembler. If the native assembler is | |
a40cbfa3 | 731 | used, it should become obvious pretty quickly what the problem is. |
252b5132 | 732 | |
a40cbfa3 | 733 | * Usage message is available with "--help". |
252b5132 | 734 | |
fa94de6b | 735 | * The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 |
a40cbfa3 | 736 | also, but didn't get into the NEWS file.) |
252b5132 | 737 | |
a40cbfa3 | 738 | * Weak symbol support for a.out. |
252b5132 | 739 | |
fa94de6b | 740 | * A bug in the listing code which could cause an infinite loop has been fixed. |
a40cbfa3 | 741 | Bugs in listings when generating a COFF object file have also been fixed. |
252b5132 | 742 | |
a40cbfa3 NC |
743 | * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by |
744 | Paul Kranenburg. | |
252b5132 | 745 | |
a40cbfa3 NC |
746 | * Improved Alpha support. Immediate constants can have a much larger range |
747 | now. Support for the 21164 has been contributed by Digital. | |
252b5132 | 748 | |
a40cbfa3 | 749 | * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. |
252b5132 RH |
750 | |
751 | Changes in 2.3: | |
752 | ||
a40cbfa3 | 753 | * Mach i386 support, by David Mackenzie and Ken Raeburn. |
252b5132 | 754 | |
a40cbfa3 | 755 | * RS/6000 and PowerPC support by Ian Taylor. |
252b5132 | 756 | |
a40cbfa3 NC |
757 | * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, |
758 | based on mail received from various people. The `-h#' option should work | |
759 | again too. | |
252b5132 | 760 | |
a40cbfa3 | 761 | * HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work |
fa94de6b | 762 | with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special |
a40cbfa3 NC |
763 | version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve |
764 | this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu | |
765 | in the "dist" directory. | |
252b5132 | 766 | |
a40cbfa3 NC |
767 | * Vax support in gas fixed for BSD, so it builds and seems to run a couple |
768 | simple tests okay. I haven't put it through extensive testing. (GNU make is | |
769 | currently required for BSD 4.3 builds.) | |
252b5132 | 770 | |
fa94de6b | 771 | * Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is |
a40cbfa3 NC |
772 | based on code donated by CMU, which used an a.out-based format. I'm afraid |
773 | the alpha-a.out support is pretty badly mangled, and much of it removed; | |
774 | making it work will require rewriting it as BFD support for the format anyways. | |
252b5132 | 775 | |
a40cbfa3 | 776 | * Irix 5 support. |
252b5132 | 777 | |
fa94de6b | 778 | * The test suites have been fixed up a bit, so that they should work with a |
a40cbfa3 | 779 | couple different versions of expect and dejagnu. |
252b5132 | 780 | |
fa94de6b RM |
781 | * Symbols' values are now handled internally as expressions, permitting more |
782 | flexibility in evaluating them in some cases. Some details of relocation | |
a40cbfa3 NC |
783 | handling have also changed, and simple constant pool management has been |
784 | added, to make the Alpha port easier. | |
252b5132 | 785 | |
a40cbfa3 NC |
786 | * New option "--statistics" for printing out program run times. This is |
787 | intended to be used with the gcc "-Q" option, which prints out times spent in | |
788 | various phases of compilation. (You should be able to get all of them | |
789 | printed out with "gcc -Q -Wa,--statistics", I think.) | |
252b5132 RH |
790 | |
791 | Changes in 2.2: | |
792 | ||
a40cbfa3 | 793 | * RS/6000 AIX and MIPS SGI Irix 5 support has been added. |
252b5132 | 794 | |
fa94de6b RM |
795 | * Configurations that are still in development (and therefore are convenient to |
796 | have listed in configure.in) still get rejected without a minor change to | |
a40cbfa3 NC |
797 | gas/Makefile.in, so people not doing development work shouldn't get the |
798 | impression that support for such configurations is actually believed to be | |
799 | reliable. | |
252b5132 | 800 | |
fa94de6b | 801 | * The program name (usually "as") is printed when a fatal error message is |
a40cbfa3 NC |
802 | displayed. This should prevent some confusion about the source of occasional |
803 | messages about "internal errors". | |
252b5132 | 804 | |
fa94de6b | 805 | * ELF support is falling into place. Support for the 386 should be working. |
a40cbfa3 | 806 | Support for SPARC Solaris is in. HPPA support from Utah is being integrated. |
252b5132 | 807 | |
a40cbfa3 NC |
808 | * Symbol values are maintained as expressions instead of being immediately |
809 | boiled down to add-symbol, sub-symbol, and constant. This permits slightly | |
810 | more complex calculations involving symbols whose values are not alreadey | |
811 | known. | |
252b5132 | 812 | |
a40cbfa3 | 813 | * DBX-style debugging info ("stabs") is now supported for COFF formats. |
fa94de6b RM |
814 | If any stabs directives are seen in the source, GAS will create two new |
815 | sections: a ".stab" and a ".stabstr" section. The format of the .stab | |
a40cbfa3 NC |
816 | section is nearly identical to the a.out symbol format, and .stabstr is |
817 | its string table. For this to be useful, you must have configured GCC | |
818 | to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB | |
819 | that can use the stab sections (4.11 or later). | |
252b5132 | 820 | |
fa94de6b | 821 | * LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS |
a40cbfa3 | 822 | support is in progress. |
252b5132 RH |
823 | |
824 | Changes in 2.1: | |
825 | ||
fa94de6b | 826 | * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been |
a40cbfa3 | 827 | incorporated, but not well tested yet. |
252b5132 | 828 | |
fa94de6b | 829 | * Altered the opcode table split for m68k; it should require less VM to compile |
a40cbfa3 | 830 | with gcc now. |
252b5132 | 831 | |
a40cbfa3 NC |
832 | * Some minor adjustments to add (Convergent Technologies') Miniframe support, |
833 | suggested by Ronald Cole. | |
252b5132 | 834 | |
a40cbfa3 NC |
835 | * HPPA support (running OSF only, not HPUX) has been contributed by Utah. This |
836 | includes improved ELF support, which I've started adapting for SPARC Solaris | |
837 | 2.x. Integration isn't completely, so it probably won't work. | |
252b5132 | 838 | |
a40cbfa3 | 839 | * HP9000/300 support, donated by HP, has been merged in. |
252b5132 | 840 | |
a40cbfa3 | 841 | * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. |
252b5132 | 842 | |
a40cbfa3 | 843 | * Better error messages for unsupported configurations (e.g., hppa-hpux). |
252b5132 | 844 | |
a40cbfa3 | 845 | * Test suite framework is starting to become reasonable. |
252b5132 RH |
846 | |
847 | Changes in 2.0: | |
848 | ||
a40cbfa3 | 849 | * Mostly bug fixes. |
252b5132 | 850 | |
a40cbfa3 | 851 | * Some more merging of BFD and ELF code, but ELF still doesn't work. |
252b5132 RH |
852 | |
853 | Changes in 1.94: | |
854 | ||
a40cbfa3 NC |
855 | * BFD merge is partly done. Adventurous souls may try giving configure the |
856 | "--with-bfd-assembler" option. Currently, ELF format requires it, a.out | |
857 | format accepts it; SPARC CPU accepts it. It's the default only for OS "elf" | |
858 | or "solaris". (ELF isn't really supported yet. It needs work. I've got | |
859 | some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not | |
860 | fully merged yet.) | |
252b5132 | 861 | |
a40cbfa3 NC |
862 | * The 68K opcode table has been split in half. It should now compile under gcc |
863 | without consuming ridiculous amounts of memory. | |
252b5132 | 864 | |
a40cbfa3 NC |
865 | * A couple data structures have been reduced in size. This should result in |
866 | saving a little bit of space at runtime. | |
252b5132 | 867 | |
a40cbfa3 NC |
868 | * Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF |
869 | code provided ROSE format support, which I haven't merged in yet. (I can | |
870 | make it available, if anyone wants to try it out.) Ralph's code, for BSD | |
871 | 4.4, supports a.out format. We don't have ECOFF support in just yet; it's | |
872 | coming. | |
252b5132 | 873 | |
a40cbfa3 | 874 | * Support for the Hitachi H8/500 has been added. |
252b5132 | 875 | |
a40cbfa3 NC |
876 | * VMS host and target support should be working now, thanks chiefly to Eric |
877 | Youngdale. | |
252b5132 RH |
878 | |
879 | Changes in 1.93.01: | |
880 | ||
a40cbfa3 | 881 | * For m68k, support for more processors has been added: 68040, CPU32, 68851. |
252b5132 | 882 | |
a40cbfa3 | 883 | * For i386, .align is now power-of-two; was number-of-bytes. |
252b5132 | 884 | |
a40cbfa3 NC |
885 | * For m68k, "%" is now accepted before register names. For COFF format, which |
886 | doesn't use underscore prefixes for C labels, it is required, so variable "a0" | |
887 | can be distinguished from the register. | |
252b5132 | 888 | |
a40cbfa3 NC |
889 | * Last public release was 1.38. Lots of configuration changes since then, lots |
890 | of new CPUs and formats, lots of bugs fixed. | |
