3 | ||
3d3d428f NC |
4 | * Support for the National Semiconductor CR16 target has been added. |
5 | ||
3f9ce309 AM |
6 | * Added gas .reloc pseudo. This is a low-level interface for creating |
7 | relocations. | |
8 | ||
99ad8390 NC |
9 | * Add support for x86_64 PE+ target. |
10 | ||
1c0d3aa6 | 11 | * Add support for Score target. |

ec2655a6 NC |
13 | Changes in 2.17: |
14 | ||
d70c5fc7 NC |
15 | * Support for the Infineon XC16X has been added by KPIT Cummins Infosystems. |
16 | ||
08333dc4 NS |
17 | * Support for ms2 architecture has been added. |
18 | ||
b7b8fb1d NC |
19 | * Support for the Z80 processor family has been added. |
20 | ||
3e8a519c MM |
21 | * Add support for the "@<file>" syntax to the command line, so that extra |
22 | switches can be read from <file>. | |
23 | ||
37dedf66 NC |
24 | * The SH target supports a new command line switch --enable-reg-prefix which, |
25 | if enabled, will allow register names to be optionally prefixed with a $ | |
26 | character. This allows register names to be distinguished from label names. | |
27 | ||
6eaeac8a JB |
28 | * Macros with a variable number of arguments are now supported. See the |
29 | documentation for how this works. | |
30 | ||
4bdd3565 NC |
31 | * Added --reduce-memory-overheads switch to reduce the size of the hash |
32 | tables used, at the expense of longer assembly times, and | |
33 | --hash-size=<NUMBER> to set the size of the hash tables used by gas. | |
34 | ||
5e75c3ab JB |
35 | * Macro names and macro parameter names can now be any identifier that would |
36 | also be legal as a symbol elsewhere. For macro parameter names, this is | |
37 | known to cause problems in certain sources when the respective target uses | |
38 | characters inconsistently, and thus macro parameter references may no longer | |
39 | be recognized as such (see the documentation for details). | |
4bdd3565 | 40 | |
d2c5f73e NC |
41 | * Support the .f_floating, .d_floating, .g_floating and .h_floating directives |
42 | for the VAX target in order to be more compatible with the VAX MACRO | |
43 | assembler. | |
44 | ||
8c2fda1d L |
45 | * New command line option -mtune=[itanium1|itanium2] for IA64 targets. |

51 | * New command line option -mhint.b=[ok|warning|error] for IA64 targets. |
52 | ||
970d6792 L |
53 | * New command line option -munwind-check=[warning|error] for IA64 |
54 | targets. | |
55 | ||
f1dab70d JB |
56 | * The IA64 port now uses automatic dependency violation removal as its default |
57 | mode. | |
58 | ||
7499d566 NC |
59 | * Port to MAXQ processor contributed by HCL Tech. |

64 | preferred debug format. | |
65 | ||
1fe1f39c NC |
66 | * Support for the crx-elf target added. |
67 | ||
1a320fbb | 68 | * Support for the sh-symbianelf target added. |
1fe1f39c | 69 | |
0503b355 BF |
70 | * Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations |
71 | on pe[i]-i386; required for this target's DWARF 2 support. | |
72 | ||
6b6e92f4 NC |
73 | * Support for Motorola MCF521x/5249/547x/548x added. |
74 | ||
fd99574b NC |
75 | * Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC |
76 | instrucitons. | |
77 | ||
aa6975fb ILT |
78 | * New command line option -mno-shared for MIPS ELF targets. |
79 | ||
caa32fe5 NC |
80 | * New command line option --alternate and pseudo-ops .altmacro and .noaltmacro |
81 | added to enter (and leave) alternate macro syntax mode. | |
82 | ||
0477af35 NC |
83 | Changes in 2.15: |
84 | ||
7a7f4e42 CD |
85 | * The MIPS -membedded-pic option (Embedded-PIC code generation) is |
86 | deprecated and will be removed in a future release. | |
87 | ||
6edf0760 NC |
88 | * Added PIC m32r Linux (ELF) and support to M32R assembler. |
89 | ||
09d92015 MM |
90 | * Added support for ARM V6. |
91 | ||
88da98f3 MS |
92 | * Added support for sh4a and variants. |
93 | ||
eb764db8 NC |
94 | * Support for Renesas M32R2 added. |
95 | ||
88da98f3 MS |
96 | * Limited support for Mapping Symbols as specified in the ARM ELF |
97 | specification has been added to the arm assembler. | |
ed769ec1 | 98 | |
0bbf2aa4 NC |
99 | * On ARM architectures, added a new gas directive ".unreq" that undoes |
100 | definitions created by ".req". | |
101 | ||
3e602632 NC |
102 | * Support for Motorola ColdFire MCF528x added. |
103 | ||
05da4302 NC |
104 | * Added --gstabs+ switch to enable the generation of STABS debug format |
105 | information with GNU extensions. | |
106 | ||
6a265366 CD |
107 | * Added support for MIPS64 Release 2. |
108 | ||
8ad30312 NC |
109 | * Added support for v850e1. |
110 | ||
12b55ccc L |
111 | * Added -n switch for x86 assembler. By default, x86 GAS replaces |
112 | multiple nop instructions used for alignment within code sections | |
113 | with multi-byte nop instructions such as leal 0(%esi,1),%esi. This | |
114 | switch disables the optimization. | |
115 | ||
78849248 ILT |
116 | * Removed -n option from MIPS assembler. It was not useful, and confused the |
117 | existing -non_shared option. | |
118 | ||
43c58ae6 CD |
119 | Changes in 2.14: |
120 | ||
69be0a2b CD |
121 | * Added support for MIPS32 Release 2. |
122 | ||

125 | * Support for Intel's iWMMXt processor (an ARM variant) added. |
126 | ||
cce4814f NC |
127 | * An assembler test generator has been contributed and an example file that |
128 | uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c). | |
129 | ||
5177500f NC |
130 | * Support for SH2E added. |
131 | ||
fea17916 NC |
132 | * GASP has now been removed. |
133 | ||
004d9caf NC |
134 | * Support for Texas Instruments TMS320C4x and TMS320C3x series of |
135 | DSP's contributed by Michael Hayes and Svein E. Seldal. | |
026df7c5 | 136 | |
a40cbfa3 NC |
137 | * Support for the Ubicom IP2xxx microcontroller added. |
138 | ||
2cbb2eef NC |
139 | Changes in 2.13: |
140 | ||
a40cbfa3 NC |
141 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 |
142 | and FR500 included. | |
0ebb9a87 | 143 | |
a40cbfa3 | 144 | * Support for DLX processor added. |
52216602 | 145 | |
a40cbfa3 NC |
146 | * GASP has now been deprecated and will be removed in a future release. Use |
147 | the macro facilities in GAS instead. | |
3f965e60 | 148 | |
a40cbfa3 NC |
149 | * GASP now correctly parses floating point numbers. Unless the base is |
150 | explicitly specified, they are interpreted as decimal numbers regardless of | |
151 | the currently specified base. | |
1ac57253 | 152 | |
9a66911f NC |
153 | Changes in 2.12: |
154 | ||
a40cbfa3 | 155 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
49fda6c8 | 156 | |
a40cbfa3 | 157 | * Support for the OpenRISC 32-bit embedded processor by OpenCores. |
3b16e843 | 158 | |
a40cbfa3 NC |
159 | * The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for |
160 | specifying the target instruction set. The old method of specifying the | |
161 | target processor has been deprecated, but is still accepted for | |
162 | compatibility. | |
03b1477f | 163 | |
a40cbfa3 NC |
164 | * Support for the VFP floating-point instruction set has been added to |
165 | the ARM assembler. | |
252b5132 | 166 | |
a40cbfa3 NC |
167 | * New psuedo op: .incbin to include a set of binary data at a given point |
168 | in the assembly. Contributed by Anders Norlander. | |
7e005732 | 169 | |
a40cbfa3 NC |
170 | * The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated |
171 | but still works for compatability. | |
ec68c924 | 172 | |
a40cbfa3 NC |
173 | * The MIPS assembler no longer issues a warning by default when it |
174 | generates a nop instruction from a macro. The new command line option | |
175 | -n will turn on the warning. | |
63486801 | 176 | |
2dac7317 JW |
177 | Changes in 2.11: |
178 | ||
500800ca NC |
179 | * Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff. |
180 | ||
a40cbfa3 | 181 | * x86 gas now supports the full Pentium4 instruction set. |
a167610d | 182 | |
a40cbfa3 | 183 | * Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs. |
c0d8940f | 184 | |

a40cbfa3 | 193 | * Support for CRIS (Axis Communications ETRAX series). |
5bcac8a4 | 194 | |
a40cbfa3 | 195 | * x86 gas has a new .arch pseudo op to specify the target CPU architecture. |
a38cf1db | 196 | |
a40cbfa3 NC |
197 | * x86 gas -q command line option quietens warnings about register size changes |
198 | due to suffix, indirect jmp/call without `*', stand-alone prefixes, and | |
199 | translating various deprecated floating point instructions. | |
a38cf1db | 200 | |
252b5132 RH |
201 | Changes in 2.10: |
202 | ||
a40cbfa3 NC |
203 | * Support for the ARM msr instruction was changed to only allow an immediate |
204 | operand when altering the flags field. | |
d14442f4 | 205 | |
a40cbfa3 | 206 | * Support for ATMEL AVR. |
adde6300 | 207 | |
a40cbfa3 | 208 | * Support for IBM 370 ELF. Somewhat experimental. |
b5ebe70e | 209 | |
a40cbfa3 | 210 | * Support for numbers with suffixes. |
3fd9f047 | 211 | |
a40cbfa3 | 212 | * Added support for breaking to the end of repeat loops. |
6a6987a9 | 213 | |
a40cbfa3 | 214 | * Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL). |
6a6987a9 | 215 | |
a40cbfa3 | 216 | * New .elseif pseudo-op added. |
3fd9f047 | 217 | |
a40cbfa3 | 218 | * New --fatal-warnings option. |
1f776aa5 | 219 | |
a40cbfa3 | 220 | * picoJava architecture support added. |

a40cbfa3 | 222 | * Motorola MCore 210 processor support added. |
041dd5a9 | 223 | |
a40cbfa3 NC |
224 | * A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386 |
225 | assembly programs with intel syntax. | |
252b5132 | 226 | |
a40cbfa3 | 227 | * New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. |
252b5132 | 228 | |
a40cbfa3 | 229 | * Added -gdwarf2 option to generate DWARF 2 debugging information. |
041dd5a9 | 230 | |
a40cbfa3 | 231 | * Full 16-bit mode support for i386. |
252b5132 | 232 | |
a40cbfa3 NC |
233 | * Greatly improved instruction operand checking for i386. This change will |
234 | produce errors or warnings on incorrect assembly code that previous versions | |
235 | of gas accepted. If you get unexpected messages from code that worked with | |
236 | older versions of gas, please double check the code before reporting a bug. | |
252b5132 | 237 | |
a40cbfa3 | 238 | * Weak symbol support added for COFF targets. |
252b5132 | 239 | |
a40cbfa3 | 240 | * Mitsubishi D30V support added. |
252b5132 | 241 | |
a40cbfa3 | 242 | * Texas Instruments c80 (tms320c80) support added. |
252b5132 | 243 | |
a40cbfa3 | 244 | * i960 ELF support added. |
bedf545c | 245 | |
a40cbfa3 | 246 | * ARM ELF support added. |
a057431b | 247 | |
252b5132 RH |
248 | Changes in 2.9: |
249 | ||
a40cbfa3 | 250 | * Texas Instruments c30 (tms320c30) support added. |
252b5132 | 251 | |
a40cbfa3 NC |
252 | * The assembler now optimizes the exception frame information generated by egcs |
253 | and gcc 2.8. The new --traditional-format option disables this optimization. | |
252b5132 | 254 | |
a40cbfa3 | 255 | * Added --gstabs option to generate stabs debugging information. |
252b5132 | 256 | |
a40cbfa3 NC |
257 | * The -a option takes a new suboption, m (e.g., -alm) to expand macros in a |
258 | listing. | |
252b5132 | 259 | |
a40cbfa3 | 260 | * Added -MD option to print dependencies. |
252b5132 RH |
261 | |
262 | Changes in 2.8: | |
263 | ||
a40cbfa3 | 264 | * BeOS support added. |
252b5132 | 265 | |
a40cbfa3 | 266 | * MIPS16 support added. |
252b5132 | 267 | |
a40cbfa3 | 268 | * Motorola ColdFire 5200 support added (configure for m68k and use -m5200). |
252b5132 | 269 | |
a40cbfa3 | 270 | * Alpha/VMS support added. |
252b5132 | 271 | |
a40cbfa3 NC |
272 | * m68k options --base-size-default-16, --base-size-default-32, |
273 | --disp-size-default-16, and --disp-size-default-32 added. | |
252b5132 | 274 | |
a40cbfa3 NC |
275 | * The alignment directives now take an optional third argument, which is the |
276 | maximum number of bytes to skip. If doing the alignment would require | |
277 | skipping more than the given number of bytes, the alignment is not done at | |
278 | all. | |
252b5132 | 279 | |
a40cbfa3 | 280 | * The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. |
252b5132 | 281 | |
a40cbfa3 NC |
282 | * The -a option takes a new suboption, c (e.g., -alc), to skip false |
283 | conditionals in listings. | |
252b5132 | 284 | |
a40cbfa3 NC |
285 | * Added new pseudo-op, .equiv; it's like .equ, except that it is an error if |
286 | the symbol is already defined. | |
252b5132 RH |
287 | |
288 | Changes in 2.7: | |
289 | ||
a40cbfa3 NC |
290 | * The PowerPC assembler now allows the use of symbolic register names (r0, |
291 | etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) | |
292 | can be used any time. PowerPC 860 move to/from SPR instructions have been | |
293 | added. | |
252b5132 | 294 | |
a40cbfa3 | 295 | * Alpha Linux (ELF) support added. |
252b5132 | 296 | |
a40cbfa3 | 297 | * PowerPC ELF support added. |
252b5132 | 298 | |
a40cbfa3 | 299 | * m68k Linux (ELF) support added. |
252b5132 | 300 | |
a40cbfa3 | 301 | * i960 Hx/Jx support added. |
252b5132 | 302 | |
a40cbfa3 | 303 | * i386/PowerPC gnu-win32 support added. |
252b5132 | 304 | |
a40cbfa3 NC |
305 | * SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the |
306 | default is to build COFF-only support. To get a set of tools that generate | |
307 | ELF (they'll understand both COFF and ELF), you must configure with | |
308 | target=i386-unknown-sco3.2v5elf. | |
252b5132 | 309 | |
a40cbfa3 | 310 | * m88k-motorola-sysv3* support added. |
252b5132 RH |
311 | |
312 | Changes in 2.6: | |
313 | ||
a40cbfa3 | 314 | * Gas now directly supports macros, without requiring GASP. |
252b5132 | 315 | |
a40cbfa3 NC |
316 | * Gas now has an MRI assembler compatibility mode. Use -M or --mri to select |
317 | MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the | |
318 | ``.mri 0'' is seen; this can be convenient for inline assembler code. | |
252b5132 | 319 | |
a40cbfa3 | 320 | * Added --defsym SYM=VALUE option. |
252b5132 | 321 | |
a40cbfa3 | 322 | * Added -mips4 support to MIPS assembler. |
252b5132 | 323 | |
a40cbfa3 | 324 | * Added PIC support to Solaris and SPARC SunOS 4 assembler. |
252b5132 RH |
325 | |
326 | Changes in 2.4: | |
327 | ||
a40cbfa3 | 328 | * Converted this directory to use an autoconf-generated configure script. |
252b5132 | 329 | |
a40cbfa3 | 330 | * ARM support, from Richard Earnshaw. |
252b5132 | 331 | |
a40cbfa3 NC |
332 | * Updated VMS support, from Pat Rankin, including considerably improved |
333 | debugging support. | |
252b5132 | 334 | |
a40cbfa3 | 335 | * Support for the control registers in the 68060. |
252b5132 | 336 | |
a40cbfa3 NC |
337 | * Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to |
338 | provide for possible future gcc changes, for targets where gas provides some | |
339 | features not available in the native assembler. If the native assembler is | |
340 | used, it should become obvious pretty quickly what the problem is. | |
252b5132 | 341 | |
a40cbfa3 | 342 | * Usage message is available with "--help". |
252b5132 | 343 | |
a40cbfa3 NC |
344 | * The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 |
345 | also, but didn't get into the NEWS file.) | |
252b5132 | 346 | |
a40cbfa3 | 347 | * Weak symbol support for a.out. |
252b5132 | 348 | |
a40cbfa3 NC |
349 | * A bug in the listing code which could cause an infinite loop has been fixed. |
350 | Bugs in listings when generating a COFF object file have also been fixed. | |
252b5132 | 351 | |
a40cbfa3 NC |
352 | * Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by |
353 | Paul Kranenburg. | |
252b5132 | 354 | |
a40cbfa3 NC |
355 | * Improved Alpha support. Immediate constants can have a much larger range |
356 | now. Support for the 21164 has been contributed by Digital. | |
252b5132 | 357 | |
a40cbfa3 | 358 | * Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. |
252b5132 RH |
359 | |
360 | Changes in 2.3: | |
361 | ||
a40cbfa3 | 362 | * Mach i386 support, by David Mackenzie and Ken Raeburn. |
252b5132 | 363 | |
a40cbfa3 | 364 | * RS/6000 and PowerPC support by Ian Taylor. |
252b5132 | 365 | |
a40cbfa3 NC |
366 | * VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, |
367 | based on mail received from various people. The `-h#' option should work | |
368 | again too. | |
252b5132 | 369 | |
a40cbfa3 NC |
370 | * HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work |
371 | with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special | |
372 | version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve | |
373 | this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu | |
374 | in the "dist" directory. | |

376 | * Vax support in gas fixed for BSD, so it builds and seems to run a couple |
377 | simple tests okay. I haven't put it through extensive testing. (GNU make is | |
378 | currently required for BSD 4.3 builds.) | |
252b5132 | 379 | |
a40cbfa3 NC |
380 | * Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is |
381 | based on code donated by CMU, which used an a.out-based format. I'm afraid | |
382 | the alpha-a.out support is pretty badly mangled, and much of it removed; | |
383 | making it work will require rewriting it as BFD support for the format anyways. | |
252b5132 | 384 | |
a40cbfa3 | 385 | * Irix 5 support. |
252b5132 | 386 | |
a40cbfa3 NC |
387 | * The test suites have been fixed up a bit, so that they should work with a |
388 | couple different versions of expect and dejagnu. | |
252b5132 | 389 | |
a40cbfa3 NC |
390 | * Symbols' values are now handled internally as expressions, permitting more |
391 | flexibility in evaluating them in some cases. Some details of relocation | |
392 | handling have also changed, and simple constant pool management has been | |
393 | added, to make the Alpha port easier. | |
252b5132 | 394 | |
a40cbfa3 NC |
395 | * New option "--statistics" for printing out program run times. This is |
396 | intended to be used with the gcc "-Q" option, which prints out times spent in | |
397 | various phases of compilation. (You should be able to get all of them | |
398 | printed out with "gcc -Q -Wa,--statistics", I think.) | |

400 | Changes in 2.2: | |
401 | ||
a40cbfa3 | 402 | * RS/6000 AIX and MIPS SGI Irix 5 support has been added. |
252b5132 | 403 | |
a40cbfa3 NC |
404 | * Configurations that are still in development (and therefore are convenient to |
405 | have listed in configure.in) still get rejected without a minor change to | |
406 | gas/Makefile.in, so people not doing development work shouldn't get the | |
407 | impression that support for such configurations is actually believed to be | |
408 | reliable. | |
252b5132 | 409 | |
a40cbfa3 NC |
410 | * The program name (usually "as") is printed when a fatal error message is |
411 | displayed. This should prevent some confusion about the source of occasional | |
412 | messages about "internal errors". | |
252b5132 | 413 | |
a40cbfa3 NC |
414 | * ELF support is falling into place. Support for the 386 should be working. |
415 | Support for SPARC Solaris is in. HPPA support from Utah is being integrated. | |
252b5132 | 416 | |
a40cbfa3 NC |
417 | * Symbol values are maintained as expressions instead of being immediately |
418 | boiled down to add-symbol, sub-symbol, and constant. This permits slightly | |
419 | more complex calculations involving symbols whose values are not alreadey | |
420 | known. | |
252b5132 | 421 | |
a40cbfa3 NC |
422 | * DBX-style debugging info ("stabs") is now supported for COFF formats. |
423 | If any stabs directives are seen in the source, GAS will create two new | |
424 | sections: a ".stab" and a ".stabstr" section. The format of the .stab | |
425 | section is nearly identical to the a.out symbol format, and .stabstr is | |
426 | its string table. For this to be useful, you must have configured GCC | |
427 | to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB | |
428 | that can use the stab sections (4.11 or later). | |
252b5132 | 429 | |
a40cbfa3 NC |
430 | * LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS |
431 | support is in progress. | |
252b5132 RH |
432 | |
433 | Changes in 2.1: | |
434 | ||
a40cbfa3 NC |
435 | * Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been |
436 | incorporated, but not well tested yet. | |
252b5132 | 437 | |
a40cbfa3 NC |
438 | * Altered the opcode table split for m68k; it should require less VM to compile |
439 | with gcc now. | |
252b5132 | 440 | |
a40cbfa3 NC |
441 | * Some minor adjustments to add (Convergent Technologies') Miniframe support, |
442 | suggested by Ronald Cole. | |
252b5132 | 443 | |
a40cbfa3 NC |
444 | * HPPA support (running OSF only, not HPUX) has been contributed by Utah. This |
445 | includes improved ELF support, which I've started adapting for SPARC Solaris | |
446 | 2.x. Integration isn't completely, so it probably won't work. | |
252b5132 | 447 | |
a40cbfa3 | 448 | * HP9000/300 support, donated by HP, has been merged in. |
252b5132 | 449 | |
a40cbfa3 | 450 | * Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. |
252b5132 | 451 | |
a40cbfa3 | 452 | * Better error messages for unsupported configurations (e.g., hppa-hpux). |
252b5132 | 453 | |
a40cbfa3 | 454 | * Test suite framework is starting to become reasonable. |
252b5132 RH |
455 | |
456 | Changes in 2.0: | |
457 | ||
a40cbfa3 | 458 | * Mostly bug fixes. |
252b5132 | 459 | |
a40cbfa3 | 460 | * Some more merging of BFD and ELF code, but ELF still doesn't work. |
252b5132 RH |
461 | |
462 | Changes in 1.94: | |
463 | ||
a40cbfa3 NC |
464 | * BFD merge is partly done. Adventurous souls may try giving configure the |
465 | "--with-bfd-assembler" option. Currently, ELF format requires it, a.out | |
466 | format accepts it; SPARC CPU accepts it. It's the default only for OS "elf" | |
467 | or "solaris". (ELF isn't really supported yet. It needs work. I've got | |
468 | some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not | |
469 | fully merged yet.) | |
252b5132 | 470 | |
a40cbfa3 NC |
471 | * The 68K opcode table has been split in half. It should now compile under gcc |
472 | without consuming ridiculous amounts of memory. | |
252b5132 | 473 | |
a40cbfa3 NC |
474 | * A couple data structures have been reduced in size. This should result in |
475 | saving a little bit of space at runtime. | |
252b5132 | 476 | |
a40cbfa3 NC |
477 | * Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF |
478 | code provided ROSE format support, which I haven't merged in yet. (I can | |
479 | make it available, if anyone wants to try it out.) Ralph's code, for BSD | |
480 | 4.4, supports a.out format. We don't have ECOFF support in just yet; it's | |
481 | coming. | |
252b5132 | 482 | |
a40cbfa3 | 483 | * Support for the Hitachi H8/500 has been added. |
252b5132 | 484 | |
a40cbfa3 NC |
485 | * VMS host and target support should be working now, thanks chiefly to Eric |
486 | Youngdale. | |
252b5132 RH |
487 | |
488 | Changes in 1.93.01: | |
489 | ||
a40cbfa3 | 490 | * For m68k, support for more processors has been added: 68040, CPU32, 68851. |
252b5132 | 491 | |
a40cbfa3 | 492 | * For i386, .align is now power-of-two; was number-of-bytes. |
252b5132 | 493 | |
a40cbfa3 NC |
494 | * For m68k, "%" is now accepted before register names. For COFF format, which |
495 | doesn't use underscore prefixes for C labels, it is required, so variable "a0" | |
496 | can be distinguished from the register. | |
252b5132 | 497 | |
a40cbfa3 NC |
498 | * Last public release was 1.38. Lots of configuration changes since then, lots |
499 | of new CPUs and formats, lots of bugs fixed. | |
