3 | * The ARC port of objdump now accepts a -M option to specify the extra |
4 | instruction class(es) that should be disassembled. | |
5 | ||
e511c9b1 AB |
6 | * The --remove-section option for objcopy and strip now accepts section |
7 | patterns starting with an exclamation point to indicate a non-matching | |
8 | section. A non-matching section is removed from the set of sections | |
9 | matched by an earlier --remove-section pattern. | |
10 | ||
11 | * The --only-section option for objcopy now accepts section patterns | |
12 | starting with an exclamation point to indicate a non-matching section. | |
13 | A non-matching section is removed from the set of sections matched by | |
14 | an earlier --only-section pattern. | |
15 | ||
d3e5f6c8 AB |
16 | * New --remove-relocations=SECTIONPATTERN option for objcopy and strip. |
17 | This option can be used to remove sections containing relocations. | |
18 | The SECTIONPATTERN is the section to which the relocations apply, not | |
19 | the relocation section itself. | |

47 | data sections. Change the default behaviour to be --all, but add a new | |
48 | configure time option of --disable-default-strings-all to restore the old | |
49 | default behaviour. | |
50 | ||
334ac421 EA |
51 | * Add --include-all-whitespace to strings. |

103 | address before function name or source filename. | |
104 | ||
68cdf72f TG |
105 | * Add a new command line option -p / --pretty-print to addr2line to have |
106 | a more human readable output. | |
107 | ||
75875724 TG |
108 | * The hppa/som targets can now be compiled on any host. |
109 | ||
81c23f82 TG |
110 | Changes in 2.20: |
111 | ||
10e636d2 DK |
112 | * Add support for delay importing to dlltool. Use the --output-delaylib <file> |
113 | switch to create a delay-import library. The resulting app will load the dll | |
114 | as soon as the first function is called. It will link to __delayLoadHelper2() | |
115 | from the static delayimp library, which will import LoadLibraryA and | |
116 | GetProcAddress from kernel32. | |
117 | ||
3dcb3fcb | 118 | * Add a new command line option, --insn-width=WIDTH, to objdump to specify |
10e636d2 DK |
119 | number of bytes to be displayed on a single line when disassembling |
120 | instructions. | |
3dcb3fcb | 121 | |
cf13d699 NC |
122 | * Readelf can now display the relocated contents of a section as a sequence |
123 | of bytes via the --relocated-dump=<name|number> command line option. | |
124 | ||
0e27a8f6 NC |
125 | * The gprof program has been given a new command line option: |
126 | --external-symbols-table=<filename> which reads in symbols from a specified | |
127 | file. | |
6e33da12 | 128 | |
ce3c775b NC |
129 | * The plugin target has been added to bfd. It can load the same shared objects |
130 | used by gold and uses them to provide basic support for new file formats. | |
131 | ||
43cd3ced AG |
132 | * The verilog memory hex dump file format is now supported as an output format |
133 | for objcopy. | |
c067354b | 134 | |
92dd4511 L |
135 | * Add --file-alignment, --heap, --image-base, --section-alignment, |
136 | --stack and --subsystem command line options to objcopy, which will | |
137 | set PE optional header. | |
138 | ||
4cb93e3b TG |
139 | * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. |
140 | ||
141 | * --as-needed now links in a dynamic library if it satisfies undefined | |
142 | symbols in regular objects, or in other dynamic libraries. In the | |
143 | latter case the library is not linked if it is found in a DT_NEEDED | |
144 | entry of one of the libraries already linked. | |
145 | ||
0dafdf3f | 146 | * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to |
28024d9d | 147 | add absolute paths for -S. |
0dafdf3f | 148 | |
e77b97d4 KT |
149 | * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- |
150 | back to old import table generation with null element prefix. | |
151 | ||
3aade688 | 152 | * Added --identify-strict switch to cause --identify <implib> to |
71c57c16 NC |
153 | report an error when the import library is associated with |
154 | multiple DLLs. | |
155 | ||
156 | * Added --identify <implib> option to dlltool, which determines the | |
157 | name of the DLL associated with the specified <implib>. | |
158 | ||
2f3bb96a BE |
159 | * Support for PowerPC booke64 instructions has been removed. The assembler no |
160 | longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts | |
161 | -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. | |
162 | ||
6e33da12 TG |
163 | Changes in 2.19: |
164 | ||
a262ae96 NC |
165 | * Added -wL switch to dump decoded contents of .debug_line. |
166 | ||
a8da6403 NC |
167 | * Added support for "thin" archives which contain pathnames pointing to |
168 | object files rather than the files themselves and which contain a | |
169 | flattened symbol index for all objects, and archives, which have been | |
170 | added to the archive. | |
3aade688 | 171 | |
98ec6e72 NC |
172 | * Added -F switch to objdump to include file offsets in the disassembly. |
173 | ||
4145f1d5 NC |
174 | * Added -c switch to readelf to allow string dumps of archive symbol index. |
175 | ||
85f10a01 MM |
176 | * Support for SSE5 has been added to the i386 port. |
177 | ||
09c11c86 NC |
178 | * Added -p switch to readelf to allow string dumps of sections. |
179 | ||
876c34bf | 180 | Changes in 2.18: |
98ec6e72 | 181 | |
ad71ef64 NC |
182 | * Resolved 37 coding problems in bfd including static array overruns, null |
183 | pointer dereferences and use of a malloc buffer after it has been freed, as | |
184 | revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). | |
1e4cf259 | 185 | |
32866df7 NC |
186 | * The binutils sources are now released under version 3 of the GNU General |
187 | Public License. | |
188 | ||
692ed3e7 NC |
189 | * A new tool "windmc" has been added for some targets. This is a message |
190 | compiler which attempts to be compatible with the MS version. | |
191 | ||
192 | * Add codepage support to the windres tool. It now supports many new | |
193 | resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation | |
194 | for binary files is done now via bfd itself. The endianess problems | |
195 | for different hosts are solved. Dumps of .res files can now be | |
196 | re-compiled by windres without lossing resources or compilation errors. | |
197 | Some problems on dialog resource translations are corrected. | |
d856f2dd | 198 | |
d3e52d40 RS |
199 | * Add --extract-symbol command line option to objcopy, which will |
200 | strip everything out of an ordinary object file or executable except | |
201 | for its symbol table. Files containing just symbols can be useful | |
202 | to some OSes. | |
203 | ||
32866df7 NC |
204 | Changes in 2.17: |
205 | ||
aef1f6d0 DJ |
206 | * Add "-x NAME" to readelf in addition to "-x NUMBER". |
207 | ||
cbf1f5df NC |
208 | * Add -i and -t switches to cxxfilt. -i disables the display of implementation |
209 | specific extra demangling information (if any) and -t disables the demangling | |
210 | of types. | |
211 | ||
212 | * Add support for the "@<file>" syntax to the command lines of all tools, so | |
213 | that extra switches can be read from <file>. | |
214 | ||
4de2ad99 | 215 | * Add "-W/--dwarf" to objdump to display the contents of the DWARF |
cbf1f5df | 216 | debug sections. |
4de2ad99 | 217 | |
5477e8a0 | 218 | * Add "-t/--section-details" to readelf to display section details. |
cbf1f5df | 219 | "-N/--full-section-name" is deprecated. |
5477e8a0 | 220 | |
b12fe839 AM |
221 | * powerpc-linux ld now supports a variant form of PLT and GOT for the security |
222 | conscious. This form will automatically be chosen when ld detects that all | |
223 | code in regular object files was generated by gcc -msecure-plt. The old PLT | |
224 | and GOT may be forced by a new ld option, --bss-plt. | |
225 | ||
0c552dc1 FF |
226 | * Add "-i/--inlines" to addr2line to print enclosing scope information |
227 | for inlined function chains, back to first non-inlined function. | |
228 | ||
81fc812e L |
229 | * Add "-N/--full-section-name" to readelf to display full section name. |
230 | ||
ec72cfe5 NC |
231 | * Add "-M entry:<addr>" switch to objdump to specify a function entry address |
232 | when disassembling VAX binaries. | |
233 | ||
7b4a0685 NC |
234 | * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches |
235 | to objcopy to convert local symbols into global symbols. | |
3aade688 | 236 | |
9fbad737 | 237 | * gprof now allows input files to have histogram records for |
3aade688 | 238 | several memory ranges, provided those ranges are disjoint. |
7b4a0685 NC |
239 | |
240 | Changes in 2.16: | |
241 | ||
b12fe839 | 242 | * Add "-g/--section-groups" to readelf to display section groups. |
81fc812e | 243 | |
bcf32829 JB |
244 | * objcopy recognizes two new options --strip-unneeded-symbol and |
245 | --strip-unneeded-symbols, namely for use together with the wildcard | |
246 | matching the original --strip-symbol/--strip-symbols provided, but | |
247 | retaining any symbols matching but needed by relocations. | |
248 | ||
18bd398b NC |
249 | * readelf can now display address ranges from .debug_range sections. This |
250 | happens automatically when a DW_AT_range attribute is encountered. The | |
251 | command line switch --debug-dump=Ranges (or -wR) can also be used to display | |
252 | the contents of the .debug_range section. | |
253 | ||
3c9458e9 NC |
254 | * nm and objdump now have a switch "--special-syms" to enable the displaying of |
255 | symbols which the target considers to be special. By default these symbols | |
256 | are no longer displayed. Currently the only special symbols are the Mapping | |
257 | symbols used by the ARM port to mark transitions between text and data and | |
258 | between ARM and THUMB code. | |
259 | ||
607dea97 NC |
260 | * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional |
261 | import and export symbols with <preifx> prepended to them. | |
262 | ||
263 | Changes in 2.15: | |
264 | ||
e39893d7 | 265 | * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the |
9d317d34 | 266 | disassembler to print the "raw" mips instruction mnemonic instead of some |
e39893d7 FF |
267 | pseudo instruction name. I.E. print "daddu" or "or" instead of "move", |
268 | "sll" instead of "nop", etc. | |
269 | ||
5fe11841 NC |
270 | * objcopy and strip can now take wildcard patterns in symbol names specified on |
271 | the command line provided that the --wildcard switch is used to enable them. | |
272 | ||
fb52b2f4 NC |
273 | * readelf can now parse archives. |
274 | ||
51cdc6e0 NC |
275 | * objdump now accepts --debugging-tags to print the debug information in a |
276 | format compatible with ctags tool. | |
277 | ||
ed1653a7 NC |
278 | * objcopy and strip now accept --only-keep-debug to create a file containing |
279 | those sections that would be stripped out by --strip-debug. The idea is that | |
280 | this can be used in conjunction with the --add-gnu-debuglink switch to create | |
281 | a two part program distribution - one a stripped executable and the other the | |
282 | debugging info. | |
283 | ||
2593f09a NC |
284 | * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink |
285 | section into a (presumably stripped) executable. This allows the debug | |
50c2245b | 286 | information for the file to be held in a separate file. |
3aade688 | 287 | |
a3b6428f NC |
288 | * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX |
289 | single-character representation. This can be checked by running nm | |
290 | with the -a switch. | |
291 | ||
43c58ae6 CD |
292 | Changes in 2.14: |
293 | ||
7c29036b NC |
294 | * Added --info switch to objcopy and strip. |
295 | ||
3b36097d SC |
296 | * Support for Vitesse IQ2000 added by Red Hat. |
297 | ||
8745eafa NC |
298 | * Added 'S' encoding to strings to allow the display of 8-bit characters. |
299 | ||
d7fb0dd2 NC |
300 | * Added --prefix-symbols=<text>, --prefix-sections=<text> and |
301 | --prefix-alloc-sections=<text> to objcopy. | |
302 | ||
84ad6ede NC |
303 | * readelf can handle the extensions to the DWARF2 spec used by the Unified |
304 | Parallel C compiler. | |
305 | ||
7d036af2 AM |
306 | * BFD no longer declares a "boolean" type, to avoid clashes with other |
307 | headers that declare the same. Users of BFD should replace boolean, | |
308 | false and true, with int, 0 and 1, or define their own boolean type. | |
309 | ||
1e4cf259 NC |
310 | * Support for IP2K added by Denis Chertykov. |
311 | ||
2cbb2eef NC |
312 | Changes in 2.13: |
313 | ||
314 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 | |
315 | and FR500 included. | |
252b5132 | 316 | |
9a66911f NC |
317 | Changes in version 2.12: |
318 | ||
49fda6c8 HPN |
319 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
320 | ||
15c82623 NC |
321 | * size: Add --totals to display summary of sizes (Berkeley format only). |
322 | ||
d974e256 JJ |
323 | * readelf: Add --wide option to not break section header or segment listing |
324 | lines to fit into 80 columns. | |
325 | ||
d132876a NC |
326 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
327 | ||
594ef5db NC |
328 | * objcopy: Add --rename-section to change section names. |
329 | ||
e0c60db2 NC |
330 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
331 | displaying the contents of .debug.macinfo sections. | |
332 | ||
16b2b71c NC |
333 | * New command line switches added to objcopy to allow symbols to be kept as |
334 | global symbols, and also to specify files containing lists of such symbols. | |
335 | by Honda Hiroki. | |
336 | ||
87e6d782 NC |
337 | * Support for OpenRISC by Johan Rydberg. |
338 | ||
1ae8b3d2 AO |
339 | * New command line switch to objcopy --alt-machine-code which creates a binary |
340 | with an alternate machine code if one is defined in the architecture | |
341 | description. Only supported for ELF targets. By Alexandre Oliva. | |
342 | ||
43a0748c | 343 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 344 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
345 | makes sense, if the input target is binary. Otherwise it is ignored. |
346 | By Stefan Geuken. | |
347 | ||
e135f41b NC |
348 | * Support for PDP-11 by Lars Brinkhoff. |
349 | ||
09ad7db3 AM |
350 | Changes in binutils 2.11: |
351 | ||
077b8428 NC |
352 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
353 | extenstions. | |
354 | ||
355 | * Add --srec-len and --srec-forceS3 command line switch to objcopy. | |
356 | By Luciano Gemme. | |
7d036af2 | 357 | |

360 | * Support for the i860, by Jason Eckhardt. |
361 | ||
5bcac8a4 HPN |
362 | * Support for CRIS (Axis Communications ETRAX series). |
363 | ||
252b5132 RH |
364 | Changes in binutils 2.10: |
365 | ||
09ad7db3 AM |
366 | * Support for 64-bit ELF on HPPA. |
367 | ||
f1563258 TW |
368 | * New command line switch to objdump --file-start-context which shows the |
369 | entire file contents up to the source line first encountered for a given | |
7d036af2 | 370 | file. |
f1563258 | 371 | |
dd92f639 NC |
372 | * New command line switch to objdump -M (or --disassembler-options) which takes |
373 | a parameter which can then be interpreted on a per-target basis by the | |
374 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
375 | raw verions. | |
7d036af2 | 376 | |
c2c40d93 ILT |
377 | * objdump support for -mi386:intel which causes disassembly to be displayed |
378 | with intel syntax. | |
252b5132 RH |
379 | |
380 | * New program: readelf. This displays the contents of ELF format files, | |
381 | regardless of target machine. | |
382 | ||
383 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
384 | --change-section-address options. The old --adjust-section-vma option is | |
385 | equivalent to --change-section-address. The other --adjust-* options are now | |
386 | renamed to --change-*, although --adjust-* continues to work. | |
387 | ||
57938635 AM |
388 | * objcopy has a --redefine-sym option that lets you rename symbols. |
389 | ||
390 | * objcopy now takes a -j/--only-section option to copy only the specified | |
391 | sections. | |
392 | ||
252b5132 RH |
393 | * dlltool now supports the IMPORTS command. |
394 | ||
395 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
396 | --exclude-symbols, and --no-default-excludes options. | |
397 | ||
398 | Changes in binutils 2.9: | |
399 | ||
400 | * Added windres program, which can be used to manipulate resources in WIN32 | |
401 | files as used on Windows 95 and Windows NT. | |
402 | ||
403 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
404 | the VMA of the sections. | |
405 | ||
406 | * Added S modifier to ar to not build a symbol table. | |
407 | ||
408 | Changes in binutils 2.8: | |
409 | ||
410 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
411 | the new --prefix-addresses option to get the old format. There are also new | |
412 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
413 | output. | |
414 | ||
415 | * Formats may now be specified as configuration triplets. For example, | |
416 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
417 | so they must be in canonical form. | |
418 | ||
419 | * Added new addr2line program. This uses the debugging information to convert | |
420 | an address into a file name and line number within a program. | |
421 | ||
422 | * Added --change-leading-char argument to objcopy. | |
423 | ||
424 | * Added --weaken argument to objcopy. | |
425 | ||
426 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
427 | ||
428 | * Added --adjust-vma option to objdump. | |
429 | ||
430 | * Added -C/--demangle option to objdump. | |
431 | ||
432 | * Added -p/--preserve-dates option to strip and objcopy. | |
433 | ||
434 | Changes in binutils 2.7: | |
435 | ||
436 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
437 | ||
438 | * Added --debugging argument to objdump and objcopy. | |
439 | ||
440 | * Added --defined-only argument to nm. | |
441 | ||
442 | * Added --remove-leading-char argument to objcopy. | |
443 | ||
444 | * The objdump --line-numbers option is now meaningful with --reloc. | |
445 | ||
446 | * Added --line-numbers option to nm. | |
447 | ||
448 | * Added --endian/-EB/-EL option to objdump. | |
449 | ||
450 | * Added support for Alpha OpenVMS/AXP. | |
451 | ||
452 | Changes in binutils 2.6: | |
453 | ||
454 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
455 | ||
456 | * Added several arguments to objcopy to provide some control over how the new | |
457 | file is laid out in memory. Also added binary output format to BFD to permit | |
458 | generating plain binary files. | |
459 | ||
460 | * Added --start-address and --stop-address options to objdump. | |
461 | ||
462 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
463 | ||
464 | Changes in binutils 2.5: | |
465 | ||
466 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
1049f94e | 467 | listing, for a more useful listing of relocatable files. |
252b5132 RH |
468 | |
469 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
470 | Added -D/--disassemble-all option to disassemble all sections. | |
471 | ||
472 | * Added --size-sort option to nm. | |
473 | ||
474 | * strip and objcopy should now be able to handle dynamically linked ELF | |
475 | executables. | |
476 | ||
477 | Changes in binutils 2.4: | |
478 | ||
479 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
480 | PowerPC (except ar and ranlib; by Ian Taylor). | |
481 | ||
482 | * Support for Irix 5. | |
483 | ||
484 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
485 | ELF output files, since BFD currently can't create them properly. | |
486 | ||
487 | Changes in binutils 2.3: | |
488 | ||
489 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
490 | ELF and COFF files. | |
491 | ||
492 | * A new program, nlmconv, has been added. It can convert object files into | |
493 | Novell NetWare Loadable Modules. | |
494 | ||
495 | * The strings program has been added. | |
496 | ||
497 | Changes in binutils 2.2: | |
498 | ||
499 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
500 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
501 | 'cp'. | |
502 | ||
503 | * The new stand-alone program c++filt is a filter that converts encoded | |
504 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
505 | may get moved to the gcc distribution.) | |
506 | ||
507 | * nm -o on an archive now prefixes each line with the archive name, matching | |
508 | the output from BSD nm. | |
509 | ||
510 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
511 | ||
512 | * New support for H8500, Z8000, and the Hitach SH. | |
513 | ||
514 | * Dis-assembler interface changed to allow sharing with gdb. | |
515 | ||
516 | * There is new Elf code, but it is not yet ready for general use. | |
517 | ||
518 | * There is the beginnings of a test suite. | |
519 | ||
520 | Changes in binutils 2.1: | |
521 | ||
522 | * There is now support for writing ECOFF files, so ld and the other utilities | |
523 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
524 | ||
525 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
526 | version), if there are any object files in the archive. So running ranlib is | |
527 | now redundant (unless the non-standard q command is used). This is required | |
528 | for Posix.2 conformance. | |
529 | ||
530 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
531 | independently of the selected target format. This is to encourage people to | |
532 | switch to SYSV-format, which has a number of advantages. | |
533 | ||
534 | * The strip and copy programs now have options to remove debug-symbols only | |
535 | and/or local symbols only. They now also support long options. | |
