3 | * The separate debug info file options of readelf (--debug-dump=links |
4 | and --debug-dump=follow) and objdump (--dwarf=links and | |
5 | --dwarf=follow-links) will now display and/or follow multiple links if | |
6 | more than one are present in a file. (This usually happens when gcc's | |
7 | -gsplit-dwarf option is used). | |
8 | ||
39f0547e NC |
9 | In addition objdump's --dwarf=follow-links now also affects its other |
10 | display options, so that for example, when combined with --syms it will | |
11 | cause the symbol tables in any linked debug info files to also be | |
12 | displayed. In addition when combined with --disassemble the --dwarf= | |
13 | follow-links option will ensure that any symbol tables in the linked | |
14 | files are read and used when disassembling code in the main file. | |

18 | * The addr2line, c++filt, nm and objdump tools now have a limit on the |
19 | maximum amount of recursion that is allowed whilst demangling strings. | |
20 | The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT | |
21 | constant declared in the include/demangle.h header file. At the time | |
69799d67 | 22 | of writing this constant has the value of 2048. |
af03af8f NC |
23 | |
24 | The --no-recurse-limit option can be used to remove the limit, restoring | |
25 | the behaviour of earlier versions of these tools. This may be needed in | |
26 | order to dmangle truly complicated names, but it also leaves the tools | |
27 | vulnerable to stack exhaustion from maliciously constructed mangled names. | |
28 | ||

29 | * Objdump's --disassemble option can now take a parameter, specifying the |
30 | starting symbol for disassembly. Disassembly will continue from this | |
baae986a | 31 | symbol up to the next symbol or the end of the function. |

33 | * The MIPS port now supports the Loongson 2K1000 processor which implements |
34 | the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE, | |
35 | Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for | |
36 | Loongson 2K1000 processor. | |

38 | * The MIPS port now supports the Loongson 3A2000/3A3000 processor which |
39 | implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, | |
40 | Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e | |
41 | option for Loongson 3A2000/3A3000 processor. | |
42 | ||
ac8cb70f CX |
43 | * The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a, |
44 | which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE | |
45 | and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson | |
46 | 3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for | |
47 | compatibility. | |
48 | ||
46cbf38d AB |
49 | * The size tool now has a new output format '--format=GNU' or '-G'. The |
50 | results are displayed in a similar manor to the default berkeley layout, | |
51 | except read-only data is counted in the data column, not the text column. | |
52 | Additionally the total is only included once. | |

7d02540a TC |
58 | * The AArch64 port now supports showing disassembly notes which are emitted |
59 | when inconsistencies are found with the instruction that may result in the | |
60 | instruction being invalid. These can be turned on with the option -M notes | |
61 | to objdump. | |
62 | ||
63 | * The AArch64 port now emits warnings when a combination of an instruction and | |
64 | a named register could be invalid. | |
65 | ||
1869e86f AB |
66 | * Added O modifier to ar to display member offsets inside an archive |

70 | * Add --debug-dump=links option to readelf and --dwarf=links option to objdump |
71 | which displays the contents of any .gnu_debuglink or .gnu_debugaltlink | |
72 | sections. | |
73 | ||
74 | Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links | |
75 | option to objdump which causes indirect links into separate debug info files | |
76 | to be followed when dumping other DWARF sections. | |

96 | ||
efdf7a02 | 97 | * Add support for the wasm32 ELF conversion of the WebAssembly file format. |
f96bd6c2 | 98 | |
4a14e306 AK |
99 | * Add --inlines option to objdump, which extends the --line-numbers option |
100 | so that inlined functions will display their nesting information. | |
101 | ||
9ef920e9 NC |
102 | * Add --merge-notes options to objcopy to reduce the size of notes in |
103 | a binary file by merging and deleting redundant notes. | |
104 | ||
2425a30e NC |
105 | * Add support for locating separate debug info files using the build-id |
106 | method, where the separate file has a name based upon the build-id of | |
107 | the original file. | |

109 | Changes in 2.28: |
110 | ||
08dc996f AM |
111 | * This version of binutils fixes a problem with PowerPC VLE 16A and 16D |
112 | relocations which were functionally swapped, for example, | |
113 | R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D | |
114 | performed like R_PPC_VLE_HA16A. This could have been fixed by | |
115 | renumbering relocations, which would keep object files created by an | |
116 | older version of gas compatible with a newer ld. However, that would | |
117 | require an ABI update, affecting other assemblers and linkers that | |
118 | create and process the relocations correctly. It is recommended that | |
119 | all VLE object files be recompiled, but ld can modify the relocations | |
a05a5b64 | 120 | if --vle-reloc-fixup is passed to ld. If the new ld command-line |
08dc996f AM |
121 | option is not used, ld will ld warn on finding relocations inconsistent |
122 | with the instructions being relocated. | |
123 | ||
a05a5b64 | 124 | * The nm program has a new command-line option (--with-version-strings) |
df2c87b5 NC |
125 | which will display a symbol's version information, if any, after the |
126 | symbol's name. | |
127 | ||
37fd5ef3 CZ |
128 | * The ARC port of objdump now accepts a -M option to specify the extra |
129 | instruction class(es) that should be disassembled. | |
130 | ||
e511c9b1 AB |
131 | * The --remove-section option for objcopy and strip now accepts section |
132 | patterns starting with an exclamation point to indicate a non-matching | |
133 | section. A non-matching section is removed from the set of sections | |
134 | matched by an earlier --remove-section pattern. | |
135 | ||
136 | * The --only-section option for objcopy now accepts section patterns | |
137 | starting with an exclamation point to indicate a non-matching section. | |
138 | A non-matching section is removed from the set of sections matched by | |
139 | an earlier --only-section pattern. | |
140 | ||
d3e5f6c8 AB |
141 | * New --remove-relocations=SECTIONPATTERN option for objcopy and strip. |
142 | This option can be used to remove sections containing relocations. | |
143 | The SECTIONPATTERN is the section to which the relocations apply, not | |
144 | the relocation section itself. | |
145 | ||
96a84ea3 TG |
146 | Changes in 2.27: |
147 | ||
e6cc316a L |
148 | * Add a configure option, --enable-64-bit-archive, to force use of a |
149 | 64-bit format when creating an archive symbol index. | |
150 | ||
b8871f35 L |
151 | * Add --elf-stt-common= option to objcopy for ELF targets to control |
152 | whether to convert common symbols to the STT_COMMON type. | |
153 | ||
7feec526 TG |
154 | Changes in 2.26: |
155 | ||
2b35fb28 RH |
156 | * Add option to objcopy to insert new symbols into a file: |

161 | * Extend objcopy --compress-debug-sections option to support |
162 | --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF | |
163 | targets. | |
164 | ||
acf1419f AB |
165 | * Add --update-section option to objcopy. |

171 | * Add --data option to strings to only print strings in loadable, initialized |
172 | data sections. Change the default behaviour to be --all, but add a new | |
173 | configure time option of --disable-default-strings-all to restore the old | |
174 | default behaviour. | |
175 | ||
334ac421 EA |

202 | passed to preprocessor. | |
44f45767 | 203 | |
fd2f0033 TT |
204 | * Add --dwarf-start and --dwarf-end to readelf and objdump. These are used by |
205 | the new Emacs mode, see dwarf-mode.el. | |
206 | ||
69f56ae1 WL |
207 | * Add support for the Tilera TILEPro and TILE-Gx architectures. |

209 | changes in 2.21: | |
44f45767 | 210 | |
b7dd81f7 NC |
211 | * Add --interleave-width option to objcopy to allowing copying a range of |
212 | bytes from the input to the output with the --interleave option. | |
213 | ||
40b36596 JM |
214 | * Add support for the TMS320C6000 (TI C6X) processor family. |
215 | ||
0b6ae522 DJ |
216 | * Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using |
217 | the -u / --unwind option. | |
218 | ||
2c610e4b L |
219 | * Add --dyn-syms to readelf to dump dynamic symbol table. |
220 | ||
d2420a8c NC |
221 | * A new tool - elfedit - has been added to directly manipulate ELF format |
222 | binaries. | |
81c23f82 | 223 | |
bf201fdd KT |
224 | * Add to dlltool .def file feature of aliasing PE internal symbol name by |
225 | '== <ID>' option. | |
226 | ||
a05a5b64 | 227 | * Add a new command-line option -a / --addresses to addr2line to display the |
be6f6493 TG |
228 | address before function name or source filename. |
229 | ||
a05a5b64 | 230 | * Add a new command-line option -p / --pretty-print to addr2line to have |
68cdf72f TG |
231 | a more human readable output. |
232 | ||
75875724 TG |
233 | * The hppa/som targets can now be compiled on any host. |
234 | ||
81c23f82 TG |
235 | Changes in 2.20: |
236 | ||
10e636d2 DK |
237 | * Add support for delay importing to dlltool. Use the --output-delaylib <file> |
238 | switch to create a delay-import library. The resulting app will load the dll | |
239 | as soon as the first function is called. It will link to __delayLoadHelper2() | |
240 | from the static delayimp library, which will import LoadLibraryA and | |
241 | GetProcAddress from kernel32. | |
242 | ||
a05a5b64 | 243 | * Add a new command-line option, --insn-width=WIDTH, to objdump to specify |
10e636d2 DK |
244 | number of bytes to be displayed on a single line when disassembling |
245 | instructions. | |
3dcb3fcb | 246 | |
cf13d699 | 247 | * Readelf can now display the relocated contents of a section as a sequence |
a05a5b64 | 248 | of bytes via the --relocated-dump=<name|number> command-line option. |
cf13d699 | 249 | |
a05a5b64 | 250 | * The gprof program has been given a new command-line option: |
0e27a8f6 NC |
251 | --external-symbols-table=<filename> which reads in symbols from a specified |
252 | file. | |
6e33da12 | 253 | |
ce3c775b NC |
254 | * The plugin target has been added to bfd. It can load the same shared objects |
255 | used by gold and uses them to provide basic support for new file formats. | |
256 | ||
43cd3ced AG |
257 | * The verilog memory hex dump file format is now supported as an output format |
258 | for objcopy. | |
c067354b | 259 | |
92dd4511 | 260 | * Add --file-alignment, --heap, --image-base, --section-alignment, |
a05a5b64 | 261 | --stack and --subsystem command-line options to objcopy, which will |
92dd4511 L |
262 | set PE optional header. |
263 | ||
4cb93e3b TG |
264 | * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. |
265 | ||
266 | * --as-needed now links in a dynamic library if it satisfies undefined | |
267 | symbols in regular objects, or in other dynamic libraries. In the | |
268 | latter case the library is not linked if it is found in a DT_NEEDED | |
269 | entry of one of the libraries already linked. | |
270 | ||
0dafdf3f | 271 | * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to |
28024d9d | 272 | add absolute paths for -S. |
0dafdf3f | 273 | |
e77b97d4 KT |
274 | * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- |
275 | back to old import table generation with null element prefix. | |
276 | ||
3aade688 | 277 | * Added --identify-strict switch to cause --identify <implib> to |
71c57c16 NC |
278 | report an error when the import library is associated with |
279 | multiple DLLs. | |
280 | ||
281 | * Added --identify <implib> option to dlltool, which determines the | |
282 | name of the DLL associated with the specified <implib>. | |
283 | ||
2f3bb96a BE |
284 | * Support for PowerPC booke64 instructions has been removed. The assembler no |
285 | longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts | |
286 | -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. | |
287 | ||
6e33da12 TG |
288 | Changes in 2.19: |
289 | ||
a262ae96 NC |
290 | * Added -wL switch to dump decoded contents of .debug_line. |
291 | ||
a8da6403 NC |
292 | * Added support for "thin" archives which contain pathnames pointing to |
293 | object files rather than the files themselves and which contain a | |
294 | flattened symbol index for all objects, and archives, which have been | |
295 | added to the archive. | |
3aade688 | 296 | |
98ec6e72 NC |
297 | * Added -F switch to objdump to include file offsets in the disassembly. |
298 | ||
4145f1d5 NC |
299 | * Added -c switch to readelf to allow string dumps of archive symbol index. |
300 | ||
85f10a01 MM |
301 | * Support for SSE5 has been added to the i386 port. |
302 | ||
09c11c86 NC |
303 | * Added -p switch to readelf to allow string dumps of sections. |
304 | ||
876c34bf | 305 | Changes in 2.18: |
98ec6e72 | 306 | |
ad71ef64 NC |
307 | * Resolved 37 coding problems in bfd including static array overruns, null |
308 | pointer dereferences and use of a malloc buffer after it has been freed, as | |
309 | revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). | |
1e4cf259 | 310 | |
32866df7 NC |
311 | * The binutils sources are now released under version 3 of the GNU General |
312 | Public License. | |
313 | ||
692ed3e7 NC |
314 | * A new tool "windmc" has been added for some targets. This is a message |
315 | compiler which attempts to be compatible with the MS version. | |
316 | ||
317 | * Add codepage support to the windres tool. It now supports many new | |
318 | resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation | |
319 | for binary files is done now via bfd itself. The endianess problems | |
320 | for different hosts are solved. Dumps of .res files can now be | |
321 | re-compiled by windres without lossing resources or compilation errors. | |
322 | Some problems on dialog resource translations are corrected. | |
d856f2dd | 323 | |
a05a5b64 | 324 | * Add --extract-symbol command-line option to objcopy, which will |
d3e52d40 RS |
325 | strip everything out of an ordinary object file or executable except |
326 | for its symbol table. Files containing just symbols can be useful | |
327 | to some OSes. | |
328 | ||
32866df7 NC |
329 | Changes in 2.17: |
330 | ||
aef1f6d0 DJ |
331 | * Add "-x NAME" to readelf in addition to "-x NUMBER". |
332 | ||
cbf1f5df NC |
333 | * Add -i and -t switches to cxxfilt. -i disables the display of implementation |
334 | specific extra demangling information (if any) and -t disables the demangling | |
335 | of types. | |
336 | ||
337 | * Add support for the "@<file>" syntax to the command lines of all tools, so | |
338 | that extra switches can be read from <file>. | |
339 | ||
4de2ad99 | 340 | * Add "-W/--dwarf" to objdump to display the contents of the DWARF |
cbf1f5df | 341 | debug sections. |
4de2ad99 | 342 | |
5477e8a0 | 343 | * Add "-t/--section-details" to readelf to display section details. |
cbf1f5df | 344 | "-N/--full-section-name" is deprecated. |
5477e8a0 | 345 | |
b12fe839 AM |
346 | * powerpc-linux ld now supports a variant form of PLT and GOT for the security |
347 | conscious. This form will automatically be chosen when ld detects that all | |
348 | code in regular object files was generated by gcc -msecure-plt. The old PLT | |
349 | and GOT may be forced by a new ld option, --bss-plt. | |
350 | ||
0c552dc1 FF |
351 | * Add "-i/--inlines" to addr2line to print enclosing scope information |
352 | for inlined function chains, back to first non-inlined function. | |
353 | ||
81fc812e L |
354 | * Add "-N/--full-section-name" to readelf to display full section name. |
355 | ||
ec72cfe5 NC |
356 | * Add "-M entry:<addr>" switch to objdump to specify a function entry address |
357 | when disassembling VAX binaries. | |
358 | ||
7b4a0685 NC |
359 | * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches |
360 | to objcopy to convert local symbols into global symbols. | |
3aade688 | 361 | |
9fbad737 | 362 | * gprof now allows input files to have histogram records for |
3aade688 | 363 | several memory ranges, provided those ranges are disjoint. |
7b4a0685 NC |
364 | |
365 | Changes in 2.16: | |
366 | ||
b12fe839 | 367 | * Add "-g/--section-groups" to readelf to display section groups. |
81fc812e | 368 | |
bcf32829 JB |
369 | * objcopy recognizes two new options --strip-unneeded-symbol and |
370 | --strip-unneeded-symbols, namely for use together with the wildcard | |
371 | matching the original --strip-symbol/--strip-symbols provided, but | |
372 | retaining any symbols matching but needed by relocations. | |
373 | ||
18bd398b NC |
374 | * readelf can now display address ranges from .debug_range sections. This |
375 | happens automatically when a DW_AT_range attribute is encountered. The | |
a05a5b64 | 376 | command-line switch --debug-dump=Ranges (or -wR) can also be used to display |
18bd398b NC |
377 | the contents of the .debug_range section. |
378 | ||
3c9458e9 NC |
379 | * nm and objdump now have a switch "--special-syms" to enable the displaying of |
380 | symbols which the target considers to be special. By default these symbols | |
381 | are no longer displayed. Currently the only special symbols are the Mapping | |
382 | symbols used by the ARM port to mark transitions between text and data and | |
383 | between ARM and THUMB code. | |
384 | ||
607dea97 NC |
385 | * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional |
386 | import and export symbols with <preifx> prepended to them. | |
387 | ||
388 | Changes in 2.15: | |
389 | ||
e39893d7 | 390 | * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the |
9d317d34 | 391 | disassembler to print the "raw" mips instruction mnemonic instead of some |
e39893d7 FF |
392 | pseudo instruction name. I.E. print "daddu" or "or" instead of "move", |
393 | "sll" instead of "nop", etc. | |
394 | ||
5fe11841 NC |
395 | * objcopy and strip can now take wildcard patterns in symbol names specified on |
396 | the command line provided that the --wildcard switch is used to enable them. | |
397 | ||
fb52b2f4 NC |
398 | * readelf can now parse archives. |
399 | ||
51cdc6e0 NC |
400 | * objdump now accepts --debugging-tags to print the debug information in a |
401 | format compatible with ctags tool. | |
402 | ||
ed1653a7 NC |
403 | * objcopy and strip now accept --only-keep-debug to create a file containing |
404 | those sections that would be stripped out by --strip-debug. The idea is that | |
405 | this can be used in conjunction with the --add-gnu-debuglink switch to create | |
406 | a two part program distribution - one a stripped executable and the other the | |
407 | debugging info. | |
408 | ||
2593f09a NC |
409 | * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink |
410 | section into a (presumably stripped) executable. This allows the debug | |
50c2245b | 411 | information for the file to be held in a separate file. |
3aade688 | 412 | |
a3b6428f NC |
413 | * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX |
414 | single-character representation. This can be checked by running nm | |
415 | with the -a switch. | |
416 | ||
43c58ae6 CD |
417 | Changes in 2.14: |
418 | ||
7c29036b NC |
419 | * Added --info switch to objcopy and strip. |
420 | ||
3b36097d SC |
421 | * Support for Vitesse IQ2000 added by Red Hat. |
422 | ||
8745eafa NC |
423 | * Added 'S' encoding to strings to allow the display of 8-bit characters. |
424 | ||
d7fb0dd2 NC |
425 | * Added --prefix-symbols=<text>, --prefix-sections=<text> and |
426 | --prefix-alloc-sections=<text> to objcopy. | |
427 | ||
84ad6ede NC |
428 | * readelf can handle the extensions to the DWARF2 spec used by the Unified |
429 | Parallel C compiler. | |
430 | ||
7d036af2 AM |
431 | * BFD no longer declares a "boolean" type, to avoid clashes with other |
432 | headers that declare the same. Users of BFD should replace boolean, | |
433 | false and true, with int, 0 and 1, or define their own boolean type. | |
434 | ||
1e4cf259 NC |
435 | * Support for IP2K added by Denis Chertykov. |
436 | ||
2cbb2eef NC |
437 | Changes in 2.13: |
438 | ||
439 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 | |
440 | and FR500 included. | |
252b5132 | 441 | |
9a66911f NC |
442 | Changes in version 2.12: |
443 | ||
49fda6c8 HPN |
444 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
445 | ||
15c82623 NC |
446 | * size: Add --totals to display summary of sizes (Berkeley format only). |
447 | ||
d974e256 JJ |
448 | * readelf: Add --wide option to not break section header or segment listing |
449 | lines to fit into 80 columns. | |
450 | ||
d132876a NC |
451 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
452 | ||
594ef5db NC |
453 | * objcopy: Add --rename-section to change section names. |
454 | ||
e0c60db2 NC |
455 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
456 | displaying the contents of .debug.macinfo sections. | |
457 | ||
a05a5b64 | 458 | * New command-line switches added to objcopy to allow symbols to be kept as |
16b2b71c NC |
459 | global symbols, and also to specify files containing lists of such symbols. |
460 | by Honda Hiroki. | |
461 | ||
87e6d782 NC |
462 | * Support for OpenRISC by Johan Rydberg. |
463 | ||
a05a5b64 | 464 | * New command-line switch to objcopy --alt-machine-code which creates a binary |
1ae8b3d2 AO |
465 | with an alternate machine code if one is defined in the architecture |
466 | description. Only supported for ELF targets. By Alexandre Oliva. | |
467 | ||
a05a5b64 | 468 | * New command-line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 469 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
470 | makes sense, if the input target is binary. Otherwise it is ignored. |
471 | By Stefan Geuken. | |
472 | ||
e135f41b NC |
473 | * Support for PDP-11 by Lars Brinkhoff. |
474 | ||
09ad7db3 AM |
475 | Changes in binutils 2.11: |
476 | ||
077b8428 NC |
477 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
478 | extenstions. | |
479 | ||
a05a5b64 | 480 | * Add --srec-len and --srec-forceS3 command-line switch to objcopy. |
077b8428 | 481 | By Luciano Gemme. |
7d036af2 | 482 | |
156c2f8b NC |
483 | * Support for the MIPS32, by Anders Norlander. |
484 | ||
22b36938 JE |
485 | * Support for the i860, by Jason Eckhardt. |
486 | ||
5bcac8a4 HPN |
487 | * Support for CRIS (Axis Communications ETRAX series). |
488 | ||
252b5132 RH |
489 | Changes in binutils 2.10: |
490 | ||
09ad7db3 AM |
491 | * Support for 64-bit ELF on HPPA. |
492 | ||
a05a5b64 | 493 | * New command-line switch to objdump --file-start-context which shows the |
f1563258 | 494 | entire file contents up to the source line first encountered for a given |
7d036af2 | 495 | file. |
f1563258 | 496 | |
a05a5b64 | 497 | * New command-line switch to objdump -M (or --disassembler-options) which takes |
dd92f639 NC |
498 | a parameter which can then be interpreted on a per-target basis by the |
499 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
500 | raw verions. | |
7d036af2 | 501 | |
c2c40d93 ILT |
502 | * objdump support for -mi386:intel which causes disassembly to be displayed |
503 | with intel syntax. | |
252b5132 RH |
504 | |
505 | * New program: readelf. This displays the contents of ELF format files, | |
506 | regardless of target machine. | |
507 | ||
508 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
509 | --change-section-address options. The old --adjust-section-vma option is | |
510 | equivalent to --change-section-address. The other --adjust-* options are now | |
511 | renamed to --change-*, although --adjust-* continues to work. | |
512 | ||
57938635 AM |
513 | * objcopy has a --redefine-sym option that lets you rename symbols. |
514 | ||
515 | * objcopy now takes a -j/--only-section option to copy only the specified | |
516 | sections. | |
517 | ||
252b5132 RH |
518 | * dlltool now supports the IMPORTS command. |
519 | ||
520 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
521 | --exclude-symbols, and --no-default-excludes options. | |
522 | ||
523 | Changes in binutils 2.9: | |
524 | ||
525 | * Added windres program, which can be used to manipulate resources in WIN32 | |
526 | files as used on Windows 95 and Windows NT. | |
527 | ||
528 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
529 | the VMA of the sections. | |
530 | ||
531 | * Added S modifier to ar to not build a symbol table. | |
532 | ||
533 | Changes in binutils 2.8: | |
534 | ||
535 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
536 | the new --prefix-addresses option to get the old format. There are also new | |
537 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
538 | output. | |
539 | ||
540 | * Formats may now be specified as configuration triplets. For example, | |
541 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
542 | so they must be in canonical form. | |
543 | ||
544 | * Added new addr2line program. This uses the debugging information to convert | |
545 | an address into a file name and line number within a program. | |
546 | ||
547 | * Added --change-leading-char argument to objcopy. | |
548 | ||
549 | * Added --weaken argument to objcopy. | |
550 | ||
551 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
552 | ||
553 | * Added --adjust-vma option to objdump. | |
554 | ||
555 | * Added -C/--demangle option to objdump. | |
556 | ||
557 | * Added -p/--preserve-dates option to strip and objcopy. | |
558 | ||
559 | Changes in binutils 2.7: | |
560 | ||
561 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
562 | ||
563 | * Added --debugging argument to objdump and objcopy. | |
564 | ||
565 | * Added --defined-only argument to nm. | |
566 | ||
567 | * Added --remove-leading-char argument to objcopy. | |
568 | ||
569 | * The objdump --line-numbers option is now meaningful with --reloc. | |
570 | ||
571 | * Added --line-numbers option to nm. | |
572 | ||
573 | * Added --endian/-EB/-EL option to objdump. | |
574 | ||
575 | * Added support for Alpha OpenVMS/AXP. | |
576 | ||
577 | Changes in binutils 2.6: | |
578 | ||
579 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
580 | ||
581 | * Added several arguments to objcopy to provide some control over how the new | |
582 | file is laid out in memory. Also added binary output format to BFD to permit | |
583 | generating plain binary files. | |
584 | ||
585 | * Added --start-address and --stop-address options to objdump. | |
586 | ||
587 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
588 | ||
589 | Changes in binutils 2.5: | |
590 | ||
591 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
1049f94e | 592 | listing, for a more useful listing of relocatable files. |
252b5132 RH |
593 | |
594 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
595 | Added -D/--disassemble-all option to disassemble all sections. | |
596 | ||
597 | * Added --size-sort option to nm. | |
598 | ||
599 | * strip and objcopy should now be able to handle dynamically linked ELF | |
600 | executables. | |
601 | ||
602 | Changes in binutils 2.4: | |
603 | ||
604 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
605 | PowerPC (except ar and ranlib; by Ian Taylor). | |
606 | ||
607 | * Support for Irix 5. | |
608 | ||
609 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
610 | ELF output files, since BFD currently can't create them properly. | |
611 | ||
612 | Changes in binutils 2.3: | |
613 | ||
614 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
615 | ELF and COFF files. | |
616 | ||
617 | * A new program, nlmconv, has been added. It can convert object files into | |
618 | Novell NetWare Loadable Modules. | |
619 | ||
620 | * The strings program has been added. | |
621 | ||
622 | Changes in binutils 2.2: | |
623 | ||
624 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
625 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
626 | 'cp'. | |
627 | ||
628 | * The new stand-alone program c++filt is a filter that converts encoded | |
629 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
630 | may get moved to the gcc distribution.) | |
631 | ||
632 | * nm -o on an archive now prefixes each line with the archive name, matching | |
633 | the output from BSD nm. | |
634 | ||
635 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
636 | ||
637 | * New support for H8500, Z8000, and the Hitach SH. | |
638 | ||
639 | * Dis-assembler interface changed to allow sharing with gdb. | |
640 | ||
641 | * There is new Elf code, but it is not yet ready for general use. | |
642 | ||
643 | * There is the beginnings of a test suite. | |
644 | ||
645 | Changes in binutils 2.1: | |
646 | ||
647 | * There is now support for writing ECOFF files, so ld and the other utilities | |
648 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
649 | ||
650 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
651 | version), if there are any object files in the archive. So running ranlib is | |
652 | now redundant (unless the non-standard q command is used). This is required | |
653 | for Posix.2 conformance. | |
654 | ||
655 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
656 | independently of the selected target format. This is to encourage people to | |
657 | switch to SYSV-format, which has a number of advantages. | |
658 | ||
659 | * The strip and copy programs now have options to remove debug-symbols only | |
660 | and/or local symbols only. They now also support long options. | |
