3 | * Added --gstabs+ switch to enable the generation of STABS debug format |
4 | information with GNU extensions. | |
5 | ||
6a265366 CD |
6 | * Added support for MIPS64 Release 2. |
7 | ||
8ad30312 NC |
8 | * Added support for v850e1. |
9 | ||
12b55ccc L |
10 | * Added -n switch for x86 assembler. By default, x86 GAS replaces |
11 | multiple nop instructions used for alignment within code sections | |
12 | with multi-byte nop instructions such as leal 0(%esi,1),%esi. This | |
13 | switch disables the optimization. | |
14 | ||

22 | ||
cce4814f NC |
23 | * An assembler test generator has been contributed and an example file that |
24 | uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c). | |
25 | ||
5177500f NC |
26 | * Support for SH2E added. |
27 | ||
fea17916 NC |
28 | * GASP has now been removed. |
29 | ||
004d9caf NC |
30 | * Support for Texas Instruments TMS320C4x and TMS320C3x series of |
31 | DSP's contributed by Michael Hayes and Svein E. Seldal. | |
026df7c5 | 32 | |
a40cbfa3 NC |
33 | * Support for the Ubicom IP2xxx microcontroller added. |
34 | ||
2cbb2eef NC |
35 | Changes in 2.13: |
36 | ||
a40cbfa3 NC |
37 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 |
38 | and FR500 included. | |
0ebb9a87 | 39 | |
a40cbfa3 | 40 | * Support for DLX processor added. |
52216602 | 41 | |
a40cbfa3 NC |
42 | * GASP has now been deprecated and will be removed in a future release. Use |
43 | the macro facilities in GAS instead. | |
3f965e60 | 44 | |
a40cbfa3 NC |
45 | * GASP now correctly parses floating point numbers. Unless the base is |
46 | explicitly specified, they are interpreted as decimal numbers regardless of | |
47 | the currently specified base. | |

49 | Changes in 2.12: |
50 | ||
a40cbfa3 | 51 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
49fda6c8 | 52 | |
a40cbfa3 | 53 | * Support for the OpenRISC 32-bit embedded processor by OpenCores. |
3b16e843 | 54 | |
a40cbfa3 NC |
55 | * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for |
56 | specifying the target instruction set. The old method of specifying the | |
57 | target processor has been deprecated, but is still accepted for | |
58 | compatibility. | |
03b1477f | 59 | |
a40cbfa3 NC |
60 | * Support for the VFP floating-point instruction set has been added to |
61 | the ARM assembler. | |
252b5132 | 62 | |
a40cbfa3 NC |
63 | * New psuedo op: .incbin to include a set of binary data at a given point |
64 | in the assembly. Contributed by Anders Norlander. | |
7e005732 | 65 | |
a40cbfa3 NC |
66 | * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated |
67 | but still works for compatability. | |
ec68c924 | 68 | |
a40cbfa3 NC |
69 | * The MIPS assembler no longer issues a warning by default when it |
70 | generates a nop instruction from a macro. The new command line option | |
71 | -n will turn on the warning. | |

73 | Changes in 2.11: |
74 | ||
500800ca NC |
75 | * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff. |
76 | ||
a40cbfa3 | 77 | * x86 gas now supports the full Pentium4 instruction set. |
a167610d | 78 | |
a40cbfa3 | 79 | * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs. |
c0d8940f | 80 | |
a40cbfa3 | 81 | * Support for Motorola 68HC11 and 68HC12. |
df86943d | 82 | |
a40cbfa3 | 83 | * Support for Texas Instruments TMS320C54x (tic54x). |
39bec121 | 84 | |
a40cbfa3 | 85 | * Support for IA-64. |
2dac7317 | 86 | |
a40cbfa3 | 87 | * Support for i860, by Jason Eckhardt. |
22b36938 | 88 | |
a40cbfa3 | 89 | * Support for CRIS (Axis Communications ETRAX series). |
5bcac8a4 | 90 | |
a40cbfa3 | 91 | * x86 gas has a new .arch pseudo op to specify the target CPU architecture. |
a38cf1db | 92 | |
a40cbfa3 NC |
93 | * x86 gas -q command line option quietens warnings about register size changes |
94 | due to suffix, indirect jmp/call without `*', stand-alone prefixes, and | |
95 | translating various deprecated floating point instructions. | |
a38cf1db | 96 | |
252b5132 RH |
97 | Changes in 2.10: |
98 | ||
a40cbfa3 NC |
99 | * Support for the ARM msr instruction was changed to only allow an immediate |
100 | operand when altering the flags field. | |
d14442f4 | 101 | |
a40cbfa3 | 102 | * Support for ATMEL AVR. |
adde6300 | 103 | |
a40cbfa3 | 104 | * Support for IBM 370 ELF. Somewhat experimental. |
b5ebe70e | 105 | |
a40cbfa3 | 106 | * Support for numbers with suffixes. |
3fd9f047 | 107 | |
a40cbfa3 | 108 | * Added support for breaking to the end of repeat loops. |
6a6987a9 | 109 | |
a40cbfa3 | 110 | * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL). |
6a6987a9 | 111 | |
a40cbfa3 | 112 | * New .elseif pseudo-op added. |
3fd9f047 | 113 | |
a40cbfa3 | 114 | * New --fatal-warnings option. |
1f776aa5 | 115 | |
a40cbfa3 | 116 | * picoJava architecture support added. |
252b5132 | 117 | |
a40cbfa3 | 118 | * Motorola MCore 210 processor support added. |
041dd5a9 | 119 | |
a40cbfa3 NC |
120 | * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386 |
121 | assembly programs with intel syntax. | |
252b5132 | 122 | |
a40cbfa3 | 123 | * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. |
252b5132 | 124 | |
a40cbfa3 | 125 | * Added -gdwarf2 option to generate DWARF 2 debugging information. |
041dd5a9 | 126 | |
a40cbfa3 | 127 | * Full 16-bit mode support for i386. |
252b5132 | 128 | |
a40cbfa3 NC |
129 | * Greatly improved instruction operand checking for i386. This change will |
130 | produce errors or warnings on incorrect assembly code that previous versions | |
131 | of gas accepted. If you get unexpected messages from code that worked with | |
132 | older versions of gas, please double check the code before reporting a bug. | |
252b5132 | 133 | |
a40cbfa3 | 134 | * Weak symbol support added for COFF targets. |
252b5132 | 135 | |
a40cbfa3 | 136 | * Mitsubishi D30V support added. |
252b5132 | 137 | |
a40cbfa3 | 138 | * Texas Instruments c80 (tms320c80) support added. |
252b5132 | 139 | |
a40cbfa3 | 140 | * i960 ELF support added. |
bedf545c | 141 | |
a40cbfa3 | 142 | * ARM ELF support added. |
a057431b | 143 | |
252b5132 RH |
144 | Changes in 2.9: |
145 | ||
a40cbfa3 | 146 | * Texas Instruments c30 (tms320c30) support added. |
252b5132 | 147 | |
a40cbfa3 NC |
148 | * The assembler now optimizes the exception frame information generated by egcs |
149 | and gcc 2.8. The new --traditional-format option disables this optimization. | |
252b5132 | 150 | |
a40cbfa3 | 151 | * Added --gstabs option to generate stabs debugging information. |
252b5132 | 152 | |
a40cbfa3 NC |
153 | * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a |
154 | listing. | |
252b5132 | 155 | |
a40cbfa3 | 156 | * Added -MD option to print dependencies. |
252b5132 RH |
157 | |
158 | Changes in 2.8: | |
159 | ||
a40cbfa3 | 160 | * BeOS support added. |
252b5132 | 161 | |
a40cbfa3 | 162 | * MIPS16 support added. |
252b5132 | 163 | |
a40cbfa3 | 164 | * Motorola ColdFire 5200 support added (configure for m68k and use -m5200). |
252b5132 | 165 | |
a40cbfa3 | 166 | * Alpha/VMS support added. |
252b5132 | 167 | |
a40cbfa3 NC |
168 | * m68k options --base-size-default-16, --base-size-default-32, |
169 | --disp-size-default-16, and --disp-size-default-32 added. | |
252b5132 | 170 | |
a40cbfa3 NC |
171 | * The alignment directives now take an optional third argument, which is the |
172 | maximum number of bytes to skip. If doing the alignment would require | |
173 | skipping more than the given number of bytes, the alignment is not done at | |
174 | all. | |
252b5132 | 175 | |
a40cbfa3 | 176 | * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. |
252b5132 | 177 | |
a40cbfa3 NC |
178 | * The -a option takes a new suboption, c (e.g., -alc), to skip false |
179 | conditionals in listings. | |
252b5132 | 180 | |
a40cbfa3 NC |
181 | * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if |
182 | the symbol is already defined. | |
252b5132 RH |
183 | |
184 | Changes in 2.7: | |
185 | ||
a40cbfa3 NC |
186 | * The PowerPC assembler now allows the use of symbolic register names (r0, |
187 | etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) | |
188 | can be used any time. PowerPC 860 move to/from SPR instructions have been | |
189 | added. | |
252b5132 | 190 | |
a40cbfa3 | 191 | * Alpha Linux (ELF) support added. |
252b5132 | 192 | |
a40cbfa3 | 193 | * PowerPC ELF support added. |
252b5132 | 194 | |
a40cbfa3 | 195 | * m68k Linux (ELF) support added. |
252b5132 | 196 | |
a40cbfa3 | 197 | * i960 Hx/Jx support added. |
252b5132 | 198 | |
a40cbfa3 | 199 | * i386/PowerPC gnu-win32 support added. |
252b5132 | 200 | |
a40cbfa3 NC |
201 | * SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the |
202 | default is to build COFF-only support. To get a set of tools that generate | |
203 | ELF (they'll understand both COFF and ELF), you must configure with | |
204 | target=i386-unknown-sco3.2v5elf. | |
252b5132 | 205 | |
a40cbfa3 | 206 | * m88k-motorola-sysv3* support added. |
252b5132 RH |
207 | |
208 | Changes in 2.6: | |
209 | ||
a40cbfa3 | 210 | * Gas now directly supports macros, without requiring GASP. |
252b5132 | 211 | |
a40cbfa3 NC |
212 | * Gas now has an MRI assembler compatibility mode. Use -M or --mri to select |
213 | MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the | |
214 | ``.mri 0'' is seen; this can be convenient for inline assembler code. | |
252b5132 | 215 | |
a40cbfa3 | 216 | * Added --defsym SYM=VALUE option. |
252b5132 | 217 | |
a40cbfa3 | 218 | * Added -mips4 support to MIPS assembler. |
252b5132 | 219 | |
a40cbfa3 | 220 | * Added PIC support to Solaris and SPARC SunOS 4 assembler. |
252b5132 RH |
221 | |
222 | Changes in 2.4: | |
223 | ||
a40cbfa3 | 224 | * Converted this directory to use an autoconf-generated configure script. |
252b5132 | 225 | |
a40cbfa3 | 226 | * ARM support, from Richard Earnshaw. |
252b5132 | 227 | |
a40cbfa3 NC |
228 | * Updated VMS support, from Pat Rankin, including considerably improved |
229 | debugging support. | |
252b5132 | 230 | |
a40cbfa3 | 231 | * Support for the control registers in the 68060. |
252b5132 | 232 | |
a40cbfa3 NC |
233 | * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to |
234 | provide for possible future gcc changes, for targets where gas provides some | |
235 | features not available in the native assembler. If the native assembler is | |
236 | used, it should become obvious pretty quickly what the problem is. | |
252b5132 | 237 | |
a40cbfa3 | 238 | * Usage message is available with "--help". |
252b5132 | 239 | |
a40cbfa3 NC |
240 | * The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 |
241 | also, but didn't get into the NEWS file.) | |
252b5132 | 242 | |
a40cbfa3 | 243 | * Weak symbol support for a.out. |
252b5132 | 244 | |
a40cbfa3 NC |
245 | * A bug in the listing code which could cause an infinite loop has been fixed. |
246 | Bugs in listings when generating a COFF object file have also been fixed. | |
252b5132 | 247 | |
a40cbfa3 NC |
248 | * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by |
249 | Paul Kranenburg. | |
252b5132 | 250 | |
a40cbfa3 NC |
251 | * Improved Alpha support. Immediate constants can have a much larger range |
252 | now. Support for the 21164 has been contributed by Digital. | |
252b5132 | 253 | |
a40cbfa3 | 254 | * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. |
252b5132 RH |
255 | |
256 | Changes in 2.3: | |
257 | ||
a40cbfa3 | 258 | * Mach i386 support, by David Mackenzie and Ken Raeburn. |
252b5132 | 259 | |
a40cbfa3 | 260 | * RS/6000 and PowerPC support by Ian Taylor. |
252b5132 | 261 | |
a40cbfa3 NC |
262 | * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, |
263 | based on mail received from various people. The `-h#' option should work | |
264 | again too. | |
252b5132 | 265 | |
a40cbfa3 NC |
266 | * HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work |
267 | with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special | |
268 | version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve | |
269 | this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu | |
270 | in the "dist" directory. | |
252b5132 | 271 | |
a40cbfa3 NC |
272 | * Vax support in gas fixed for BSD, so it builds and seems to run a couple |
273 | simple tests okay. I haven't put it through extensive testing. (GNU make is | |
274 | currently required for BSD 4.3 builds.) | |
252b5132 | 275 | |
a40cbfa3 NC |
276 | * Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is |
277 | based on code donated by CMU, which used an a.out-based format. I'm afraid | |
278 | the alpha-a.out support is pretty badly mangled, and much of it removed; | |
279 | making it work will require rewriting it as BFD support for the format anyways. | |
252b5132 | 280 | |
a40cbfa3 | 281 | * Irix 5 support. |
252b5132 | 282 | |
a40cbfa3 NC |
283 | * The test suites have been fixed up a bit, so that they should work with a |
284 | couple different versions of expect and dejagnu. | |
252b5132 | 285 | |
a40cbfa3 NC |
286 | * Symbols' values are now handled internally as expressions, permitting more |
287 | flexibility in evaluating them in some cases. Some details of relocation | |
288 | handling have also changed, and simple constant pool management has been | |
289 | added, to make the Alpha port easier. | |
252b5132 | 290 | |
a40cbfa3 NC |
291 | * New option "--statistics" for printing out program run times. This is |
292 | intended to be used with the gcc "-Q" option, which prints out times spent in | |
293 | various phases of compilation. (You should be able to get all of them | |
294 | printed out with "gcc -Q -Wa,--statistics", I think.) | |
252b5132 RH |
295 | |
296 | Changes in 2.2: | |
297 | ||
a40cbfa3 | 298 | * RS/6000 AIX and MIPS SGI Irix 5 support has been added. |
252b5132 | 299 | |
a40cbfa3 NC |
300 | * Configurations that are still in development (and therefore are convenient to |
301 | have listed in configure.in) still get rejected without a minor change to | |
302 | gas/Makefile.in, so people not doing development work shouldn't get the | |
303 | impression that support for such configurations is actually believed to be | |
304 | reliable. | |
252b5132 | 305 | |
a40cbfa3 NC |
306 | * The program name (usually "as") is printed when a fatal error message is |
307 | displayed. This should prevent some confusion about the source of occasional | |
308 | messages about "internal errors". | |
252b5132 | 309 | |
a40cbfa3 NC |
310 | * ELF support is falling into place. Support for the 386 should be working. |
311 | Support for SPARC Solaris is in. HPPA support from Utah is being integrated. | |
252b5132 | 312 | |
a40cbfa3 NC |
313 | * Symbol values are maintained as expressions instead of being immediately |
314 | boiled down to add-symbol, sub-symbol, and constant. This permits slightly | |
315 | more complex calculations involving symbols whose values are not alreadey | |
316 | known. | |
252b5132 | 317 | |
a40cbfa3 NC |
318 | * DBX-style debugging info ("stabs") is now supported for COFF formats. |
319 | If any stabs directives are seen in the source, GAS will create two new | |
320 | sections: a ".stab" and a ".stabstr" section. The format of the .stab | |
321 | section is nearly identical to the a.out symbol format, and .stabstr is | |
322 | its string table. For this to be useful, you must have configured GCC | |
323 | to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB | |
324 | that can use the stab sections (4.11 or later). | |
252b5132 | 325 | |
a40cbfa3 NC |
326 | * LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS |
327 | support is in progress. | |
252b5132 RH |
328 | |
329 | Changes in 2.1: | |
330 | ||
a40cbfa3 NC |
331 | * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been |
332 | incorporated, but not well tested yet. | |
252b5132 | 333 | |
a40cbfa3 NC |
334 | * Altered the opcode table split for m68k; it should require less VM to compile |
335 | with gcc now. | |
252b5132 | 336 | |
a40cbfa3 NC |
337 | * Some minor adjustments to add (Convergent Technologies') Miniframe support, |
338 | suggested by Ronald Cole. | |
252b5132 | 339 | |
a40cbfa3 NC |
340 | * HPPA support (running OSF only, not HPUX) has been contributed by Utah. This |
341 | includes improved ELF support, which I've started adapting for SPARC Solaris | |
342 | 2.x. Integration isn't completely, so it probably won't work. | |
252b5132 | 343 | |
a40cbfa3 | 344 | * HP9000/300 support, donated by HP, has been merged in. |
252b5132 | 345 | |
a40cbfa3 | 346 | * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. |
252b5132 | 347 | |
a40cbfa3 | 348 | * Better error messages for unsupported configurations (e.g., hppa-hpux). |
252b5132 | 349 | |
a40cbfa3 | 350 | * Test suite framework is starting to become reasonable. |
252b5132 RH |
351 | |
352 | Changes in 2.0: | |
353 | ||
a40cbfa3 | 354 | * Mostly bug fixes. |
252b5132 | 355 | |
a40cbfa3 | 356 | * Some more merging of BFD and ELF code, but ELF still doesn't work. |
252b5132 RH |
357 | |
358 | Changes in 1.94: | |
359 | ||
a40cbfa3 NC |
360 | * BFD merge is partly done. Adventurous souls may try giving configure the |
361 | "--with-bfd-assembler" option. Currently, ELF format requires it, a.out | |
362 | format accepts it; SPARC CPU accepts it. It's the default only for OS "elf" | |
363 | or "solaris". (ELF isn't really supported yet. It needs work. I've got | |
364 | some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not | |
365 | fully merged yet.) | |

367 | * The 68K opcode table has been split in half. It should now compile under gcc |
368 | without consuming ridiculous amounts of memory. | |

370 | * A couple data structures have been reduced in size. This should result in |
371 | saving a little bit of space at runtime. | |

373 | * Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF |
374 | code provided ROSE format support, which I haven't merged in yet. (I can | |
375 | make it available, if anyone wants to try it out.) Ralph's code, for BSD | |
376 | 4.4, supports a.out format. We don't have ECOFF support in just yet; it's | |
377 | coming. | |

381 | * VMS host and target support should be working now, thanks chiefly to Eric |
382 | Youngdale. | |

384 | Changes in 1.93.01: | |
385 | ||
a40cbfa3 | 386 | * For m68k, support for more processors has been added: 68040, CPU32, 68851. |
252b5132 | 387 | |
a40cbfa3 | 388 | * For i386, .align is now power-of-two; was number-of-bytes. |
252b5132 | 389 | |
a40cbfa3 NC |
390 | * For m68k, "%" is now accepted before register names. For COFF format, which |
391 | doesn't use underscore prefixes for C labels, it is required, so variable "a0" | |
392 | can be distinguished from the register. | |
252b5132 | 393 | |

394 | * Last public release was 1.38. Lots of configuration changes since then, lots |
395 | of new CPUs and formats, lots of bugs fixed. | |
