117 | switches can be read from <file>. | |
118 | ||
37dedf66 NC |
119 | * The SH target supports a new command line switch --enable-reg-prefix which, |
120 | if enabled, will allow register names to be optionally prefixed with a $ | |
121 | character. This allows register names to be distinguished from label names. | |
fa94de6b | 122 | |
6eaeac8a JB |
123 | * Macros with a variable number of arguments are now supported. See the |
124 | documentation for how this works. | |
125 | ||
4bdd3565 NC |
126 | * Added --reduce-memory-overheads switch to reduce the size of the hash |
127 | tables used, at the expense of longer assembly times, and | |
128 | --hash-size=<NUMBER> to set the size of the hash tables used by gas. | |
129 | ||
5e75c3ab JB |
130 | * Macro names and macro parameter names can now be any identifier that would |
131 | also be legal as a symbol elsewhere. For macro parameter names, this is | |
132 | known to cause problems in certain sources when the respective target uses | |
133 | characters inconsistently, and thus macro parameter references may no longer | |
134 | be recognized as such (see the documentation for details). | |
fa94de6b | 135 | |
d2c5f73e NC |
136 | * Support the .f_floating, .d_floating, .g_floating and .h_floating directives |

174 | ||
caa32fe5 NC |
175 | * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro |
176 | added to enter (and leave) alternate macro syntax mode. | |
177 | ||
0477af35 NC |
178 | Changes in 2.15: |
179 | ||
7a7f4e42 CD |
180 | * The MIPS -membedded-pic option (Embedded-PIC code generation) is |
181 | deprecated and will be removed in a future release. | |

8ad30312 NC |
204 | * Added support for v850e1. |
205 | ||
12b55ccc L |
206 | * Added -n switch for x86 assembler. By default, x86 GAS replaces |
207 | multiple nop instructions used for alignment within code sections | |
208 | with multi-byte nop instructions such as leal 0(%esi,1),%esi. This | |
209 | switch disables the optimization. | |
210 | ||
78849248 ILT |
211 | * Removed -n option from MIPS assembler. It was not useful, and confused the |
212 | existing -non_shared option. | |
213 | ||
43c58ae6 CD |
214 | Changes in 2.14: |
215 | ||
69be0a2b CD |

237 | and FR500 included. | |
0ebb9a87 | 238 | |
a40cbfa3 | 239 | * Support for DLX processor added. |
52216602 | 240 | |
a40cbfa3 NC |
241 | * GASP has now been deprecated and will be removed in a future release. Use |
242 | the macro facilities in GAS instead. | |
3f965e60 | 243 | |
a40cbfa3 NC |
244 | * GASP now correctly parses floating point numbers. Unless the base is |
245 | explicitly specified, they are interpreted as decimal numbers regardless of | |
246 | the currently specified base. | |
1ac57253 | 247 | |
9a66911f NC |
248 | Changes in 2.12: |
249 | ||

49fda6c8 | 251 | |
a40cbfa3 | 252 | * Support for the OpenRISC 32-bit embedded processor by OpenCores. |
3b16e843 | 253 | |
fa94de6b RM |
254 | * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for |
255 | specifying the target instruction set. The old method of specifying the | |
a40cbfa3 NC |
256 | target processor has been deprecated, but is still accepted for |
257 | compatibility. | |
03b1477f | 258 | |
a40cbfa3 NC |
259 | * Support for the VFP floating-point instruction set has been added to |
260 | the ARM assembler. | |
252b5132 | 261 | |
a40cbfa3 NC |
262 | * New psuedo op: .incbin to include a set of binary data at a given point |
263 | in the assembly. Contributed by Anders Norlander. | |
7e005732 | 264 | |
a40cbfa3 NC |
265 | * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated |
266 | but still works for compatability. | |
ec68c924 | 267 | |
fa94de6b | 268 | * The MIPS assembler no longer issues a warning by default when it |
a40cbfa3 NC |
269 | generates a nop instruction from a macro. The new command line option |
270 | -n will turn on the warning. | |
63486801 | 271 | |
2dac7317 JW |
272 | Changes in 2.11: |
273 | ||
500800ca NC |

293 | due to suffix, indirect jmp/call without `*', stand-alone prefixes, and | |
294 | translating various deprecated floating point instructions. | |
a38cf1db | 295 | |
252b5132 RH |
296 | Changes in 2.10: |
297 | ||
a40cbfa3 NC |

a40cbfa3 | 320 | assembly programs with intel syntax. |
252b5132 | 321 | |
a40cbfa3 | 322 | * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. |
252b5132 | 323 | |
a40cbfa3 | 324 | * Added -gdwarf2 option to generate DWARF 2 debugging information. |
041dd5a9 | 325 | |
a40cbfa3 | 326 | * Full 16-bit mode support for i386. |
252b5132 | 327 | |
fa94de6b | 328 | * Greatly improved instruction operand checking for i386. This change will |
a40cbfa3 NC |
329 | produce errors or warnings on incorrect assembly code that previous versions |
330 | of gas accepted. If you get unexpected messages from code that worked with | |
331 | older versions of gas, please double check the code before reporting a bug. | |
252b5132 | 332 | |
a40cbfa3 | 333 | * Weak symbol support added for COFF targets. |
252b5132 | 334 | |

252b5132 RH |
343 | Changes in 2.9: |
344 | ||
a40cbfa3 | 345 | * Texas Instruments c30 (tms320c30) support added. |
252b5132 | 346 | |
fa94de6b | 347 | * The assembler now optimizes the exception frame information generated by egcs |
a40cbfa3 | 348 | and gcc 2.8. The new --traditional-format option disables this optimization. |
252b5132 | 349 | |
a40cbfa3 | 350 | * Added --gstabs option to generate stabs debugging information. |
252b5132 | 351 | |

a40cbfa3 NC |
367 | * m68k options --base-size-default-16, --base-size-default-32, |
368 | --disp-size-default-16, and --disp-size-default-32 added. | |
252b5132 | 369 | |
a40cbfa3 NC |
370 | * The alignment directives now take an optional third argument, which is the |
371 | maximum number of bytes to skip. If doing the alignment would require | |
372 | skipping more than the given number of bytes, the alignment is not done at | |
373 | all. | |
252b5132 | 374 | |
a40cbfa3 | 375 | * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. |
252b5132 | 376 | |
a40cbfa3 NC |
377 | * The -a option takes a new suboption, c (e.g., -alc), to skip false |
378 | conditionals in listings. | |
252b5132 | 379 | |
a40cbfa3 NC |
380 | * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if |
381 | the symbol is already defined. | |
252b5132 RH |
382 | |
383 | Changes in 2.7: | |
384 | ||
a40cbfa3 NC |
385 | * The PowerPC assembler now allows the use of symbolic register names (r0, |
386 | etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) | |
387 | can be used any time. PowerPC 860 move to/from SPR instructions have been | |
388 | added. | |
252b5132 | 389 | |
a40cbfa3 | 390 | * Alpha Linux (ELF) support added. |
252b5132 | 391 | |
a40cbfa3 | 392 | * PowerPC ELF support added. |
252b5132 | 393 | |
a40cbfa3 | 394 | * m68k Linux (ELF) support added. |
252b5132 | 395 | |
a40cbfa3 | 396 | * i960 Hx/Jx support added. |
252b5132 | 397 | |
a40cbfa3 | 398 | * i386/PowerPC gnu-win32 support added. |
252b5132 | 399 | |
a40cbfa3 NC |
400 | * SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the |
401 | default is to build COFF-only support. To get a set of tools that generate | |
fa94de6b | 402 | ELF (they'll understand both COFF and ELF), you must configure with |
a40cbfa3 | 403 | target=i386-unknown-sco3.2v5elf. |
252b5132 | 404 | |
a40cbfa3 | 405 | * m88k-motorola-sysv3* support added. |
252b5132 RH |
406 | |
407 | Changes in 2.6: | |
408 | ||
a40cbfa3 | 409 | * Gas now directly supports macros, without requiring GASP. |
252b5132 | 410 | |
a40cbfa3 NC |
411 | * Gas now has an MRI assembler compatibility mode. Use -M or --mri to select |
412 | MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the | |
413 | ``.mri 0'' is seen; this can be convenient for inline assembler code. | |
252b5132 | 414 | |
a40cbfa3 | 415 | * Added --defsym SYM=VALUE option. |
252b5132 | 416 | |
a40cbfa3 | 417 | * Added -mips4 support to MIPS assembler. |
252b5132 | 418 | |
a40cbfa3 | 419 | * Added PIC support to Solaris and SPARC SunOS 4 assembler. |
252b5132 RH |
420 | |
421 | Changes in 2.4: | |
422 | ||
a40cbfa3 | 423 | * Converted this directory to use an autoconf-generated configure script. |
252b5132 | 424 | |
a40cbfa3 | 425 | * ARM support, from Richard Earnshaw. |
252b5132 | 426 | |
a40cbfa3 NC |
427 | * Updated VMS support, from Pat Rankin, including considerably improved |
428 | debugging support. | |
252b5132 | 429 | |
a40cbfa3 | 430 | * Support for the control registers in the 68060. |
252b5132 | 431 | |
a40cbfa3 | 432 | * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to |
fa94de6b RM |
433 | provide for possible future gcc changes, for targets where gas provides some |
434 | features not available in the native assembler. If the native assembler is | |
a40cbfa3 | 435 | used, it should become obvious pretty quickly what the problem is. |
252b5132 | 436 | |
a40cbfa3 | 437 | * Usage message is available with "--help". |
252b5132 | 438 | |
fa94de6b | 439 | * The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 |
a40cbfa3 | 440 | also, but didn't get into the NEWS file.) |
252b5132 | 441 | |
a40cbfa3 | 442 | * Weak symbol support for a.out. |
252b5132 | 443 | |
fa94de6b | 444 | * A bug in the listing code which could cause an infinite loop has been fixed. |
a40cbfa3 | 445 | Bugs in listings when generating a COFF object file have also been fixed. |
252b5132 | 446 | |
a40cbfa3 NC |
447 | * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by |
448 | Paul Kranenburg. | |
252b5132 | 449 | |
a40cbfa3 NC |
450 | * Improved Alpha support. Immediate constants can have a much larger range |
451 | now. Support for the 21164 has been contributed by Digital. | |
252b5132 | 452 | |
a40cbfa3 | 453 | * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. |
252b5132 RH |
454 | |
455 | Changes in 2.3: | |
456 | ||
a40cbfa3 | 457 | * Mach i386 support, by David Mackenzie and Ken Raeburn. |
252b5132 | 458 | |
a40cbfa3 | 459 | * RS/6000 and PowerPC support by Ian Taylor. |
252b5132 | 460 | |
a40cbfa3 NC |
461 | * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, |
462 | based on mail received from various people. The `-h#' option should work | |
463 | again too. | |
252b5132 | 464 | |
a40cbfa3 | 465 | * HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work |
fa94de6b | 466 | with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special |
a40cbfa3 NC |
467 | version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve |
468 | this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu | |
469 | in the "dist" directory. | |
252b5132 | 470 | |
a40cbfa3 NC |
471 | * Vax support in gas fixed for BSD, so it builds and seems to run a couple |
472 | simple tests okay. I haven't put it through extensive testing. (GNU make is | |
473 | currently required for BSD 4.3 builds.) | |
252b5132 | 474 | |
fa94de6b | 475 | * Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is |
a40cbfa3 NC |
476 | based on code donated by CMU, which used an a.out-based format. I'm afraid |
477 | the alpha-a.out support is pretty badly mangled, and much of it removed; | |
478 | making it work will require rewriting it as BFD support for the format anyways. | |
252b5132 | 479 | |
a40cbfa3 | 480 | * Irix 5 support. |
252b5132 | 481 | |
fa94de6b | 482 | * The test suites have been fixed up a bit, so that they should work with a |
a40cbfa3 | 483 | couple different versions of expect and dejagnu. |
252b5132 | 484 | |
fa94de6b RM |
485 | * Symbols' values are now handled internally as expressions, permitting more |
486 | flexibility in evaluating them in some cases. Some details of relocation | |
a40cbfa3 NC |
487 | handling have also changed, and simple constant pool management has been |
488 | added, to make the Alpha port easier. | |
252b5132 | 489 | |
a40cbfa3 NC |
490 | * New option "--statistics" for printing out program run times. This is |
491 | intended to be used with the gcc "-Q" option, which prints out times spent in | |
492 | various phases of compilation. (You should be able to get all of them | |
493 | printed out with "gcc -Q -Wa,--statistics", I think.) | |
252b5132 RH |
494 | |
495 | Changes in 2.2: | |
496 | ||
a40cbfa3 | 497 | * RS/6000 AIX and MIPS SGI Irix 5 support has been added. |
252b5132 | 498 | |
fa94de6b RM |
499 | * Configurations that are still in development (and therefore are convenient to |
500 | have listed in configure.in) still get rejected without a minor change to | |
a40cbfa3 NC |
501 | gas/Makefile.in, so people not doing development work shouldn't get the |
502 | impression that support for such configurations is actually believed to be | |
503 | reliable. | |
252b5132 | 504 | |
fa94de6b | 505 | * The program name (usually "as") is printed when a fatal error message is |
a40cbfa3 NC |
506 | displayed. This should prevent some confusion about the source of occasional |
507 | messages about "internal errors". | |
252b5132 | 508 | |
fa94de6b | 509 | * ELF support is falling into place. Support for the 386 should be working. |
a40cbfa3 | 510 | Support for SPARC Solaris is in. HPPA support from Utah is being integrated. |
252b5132 | 511 | |
a40cbfa3 NC |
512 | * Symbol values are maintained as expressions instead of being immediately |
513 | boiled down to add-symbol, sub-symbol, and constant. This permits slightly | |
514 | more complex calculations involving symbols whose values are not alreadey | |
515 | known. | |
252b5132 | 516 | |
a40cbfa3 | 517 | * DBX-style debugging info ("stabs") is now supported for COFF formats. |
fa94de6b RM |
518 | If any stabs directives are seen in the source, GAS will create two new |
519 | sections: a ".stab" and a ".stabstr" section. The format of the .stab | |
a40cbfa3 NC |
520 | section is nearly identical to the a.out symbol format, and .stabstr is |
521 | its string table. For this to be useful, you must have configured GCC | |
522 | to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB | |
523 | that can use the stab sections (4.11 or later). | |
252b5132 | 524 | |
fa94de6b | 525 | * LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS |
a40cbfa3 | 526 | support is in progress. |
252b5132 RH |
527 | |
528 | Changes in 2.1: | |
529 | ||
fa94de6b | 530 | * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been |
a40cbfa3 | 531 | incorporated, but not well tested yet. |
252b5132 | 532 | |
fa94de6b | 533 | * Altered the opcode table split for m68k; it should require less VM to compile |
a40cbfa3 | 534 | with gcc now. |
252b5132 | 535 | |
a40cbfa3 NC |
536 | * Some minor adjustments to add (Convergent Technologies') Miniframe support, |
537 | suggested by Ronald Cole. | |
252b5132 | 538 | |
a40cbfa3 NC |
539 | * HPPA support (running OSF only, not HPUX) has been contributed by Utah. This |
540 | includes improved ELF support, which I've started adapting for SPARC Solaris | |
541 | 2.x. Integration isn't completely, so it probably won't work. | |
252b5132 | 542 | |
a40cbfa3 | 543 | * HP9000/300 support, donated by HP, has been merged in. |
252b5132 | 544 | |
a40cbfa3 | 545 | * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. |
252b5132 | 546 | |
a40cbfa3 | 547 | * Better error messages for unsupported configurations (e.g., hppa-hpux). |
252b5132 | 548 | |
a40cbfa3 | 549 | * Test suite framework is starting to become reasonable. |
252b5132 RH |
550 | |
551 | Changes in 2.0: | |
552 | ||
a40cbfa3 | 553 | * Mostly bug fixes. |
252b5132 | 554 | |
a40cbfa3 | 555 | * Some more merging of BFD and ELF code, but ELF still doesn't work. |
252b5132 RH |
556 | |
557 | Changes in 1.94: | |
558 | ||
a40cbfa3 NC |
559 | * BFD merge is partly done. Adventurous souls may try giving configure the |
560 | "--with-bfd-assembler" option. Currently, ELF format requires it, a.out | |
561 | format accepts it; SPARC CPU accepts it. It's the default only for OS "elf" | |
562 | or "solaris". (ELF isn't really supported yet. It needs work. I've got | |
563 | some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not | |
564 | fully merged yet.) | |
252b5132 | 565 | |
a40cbfa3 NC |
566 | * The 68K opcode table has been split in half. It should now compile under gcc |
567 | without consuming ridiculous amounts of memory. | |
252b5132 | 568 | |
a40cbfa3 NC |
569 | * A couple data structures have been reduced in size. This should result in |
570 | saving a little bit of space at runtime. | |
252b5132 | 571 | |
a40cbfa3 NC |
572 | * Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF |
573 | code provided ROSE format support, which I haven't merged in yet. (I can | |
574 | make it available, if anyone wants to try it out.) Ralph's code, for BSD | |
575 | 4.4, supports a.out format. We don't have ECOFF support in just yet; it's | |
576 | coming. | |
252b5132 | 577 | |
a40cbfa3 | 578 | * Support for the Hitachi H8/500 has been added. |
252b5132 | 579 | |
a40cbfa3 NC |
580 | * VMS host and target support should be working now, thanks chiefly to Eric |
581 | Youngdale. | |
252b5132 RH |
582 | |
583 | Changes in 1.93.01: | |
584 | ||
a40cbfa3 | 585 | * For m68k, support for more processors has been added: 68040, CPU32, 68851. |
252b5132 | 586 | |
a40cbfa3 | 587 | * For i386, .align is now power-of-two; was number-of-bytes. |
252b5132 | 588 | |
a40cbfa3 NC |
589 | * For m68k, "%" is now accepted before register names. For COFF format, which |
590 | doesn't use underscore prefixes for C labels, it is required, so variable "a0" | |
591 | can be distinguished from the register. | |
252b5132 | 592 | |
a40cbfa3 NC |
593 | * Last public release was 1.38. Lots of configuration changes since then, lots |
594 | of new CPUs and formats, lots of bugs fixed. | |
