37d0d091 JH |
5 | * Add --verilog-data-width option to objcopy for verilog targets to control |
6 | width of data elements in verilog hex format. | |
7 | ||
514bbb0f AV |
8 | * Add support for the Armv8.1-M Mainline and M-profile Vector Extension (MVE) |
9 | instructions. | |
10 | ||
24841daa NC |
11 | * The separate debug info file options of readelf (--debug-dump=links |
12 | and --debug-dump=follow) and objdump (--dwarf=links and | |
13 | --dwarf=follow-links) will now display and/or follow multiple links if | |
14 | more than one are present in a file. (This usually happens when gcc's | |
15 | -gsplit-dwarf option is used). | |
16 | ||
39f0547e NC |
17 | In addition objdump's --dwarf=follow-links now also affects its other |
18 | display options, so that for example, when combined with --syms it will | |
19 | cause the symbol tables in any linked debug info files to also be | |
20 | displayed. In addition when combined with --disassemble the --dwarf= | |
21 | follow-links option will ensure that any symbol tables in the linked | |
22 | files are read and used when disassembling code in the main file. | |

23 | |
24 | * Add support for dumping types encoded in the Compact Type Format | |
25 | to objdump and readelf. | |

af03af8f NC |
29 | * The addr2line, c++filt, nm and objdump tools now have a limit on the |
30 | maximum amount of recursion that is allowed whilst demangling strings. | |
31 | The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT | |
32 | constant declared in the include/demangle.h header file. At the time | |
69799d67 | 33 | of writing this constant has the value of 2048. |
af03af8f NC |
34 | |
35 | The --no-recurse-limit option can be used to remove the limit, restoring | |
36 | the behaviour of earlier versions of these tools. This may be needed in | |
37 | order to dmangle truly complicated names, but it also leaves the tools | |
38 | vulnerable to stack exhaustion from maliciously constructed mangled names. | |
39 | ||
d3def5d7 MY |
40 | * Objdump's --disassemble option can now take a parameter, specifying the |
41 | starting symbol for disassembly. Disassembly will continue from this | |
baae986a | 42 | symbol up to the next symbol or the end of the function. |

44 | * The MIPS port now supports the Loongson 2K1000 processor which implements |
45 | the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE, | |
46 | Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for | |
47 | Loongson 2K1000 processor. | |
48 | ||
bd782c07 CX |
49 | * The MIPS port now supports the Loongson 3A2000/3A3000 processor which |
50 | implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, | |
51 | Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e | |
52 | option for Loongson 3A2000/3A3000 processor. | |
53 | ||
ac8cb70f CX |
54 | * The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a, |
55 | which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE | |
56 | and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson | |
57 | 3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for | |
58 | compatibility. | |
59 | ||
46cbf38d AB |
60 | * The size tool now has a new output format '--format=GNU' or '-G'. The |
61 | results are displayed in a similar manor to the default berkeley layout, | |
62 | except read-only data is counted in the data column, not the text column. | |
63 | Additionally the total is only included once. | |

7d02540a TC |
69 | * The AArch64 port now supports showing disassembly notes which are emitted |
70 | when inconsistencies are found with the instruction that may result in the | |
71 | instruction being invalid. These can be turned on with the option -M notes | |
72 | to objdump. | |
73 | ||
74 | * The AArch64 port now emits warnings when a combination of an instruction and | |
75 | a named register could be invalid. | |
76 | ||
1869e86f AB |
77 | * Added O modifier to ar to display member offsets inside an archive |

80 | ||
dda8d76d NC |
81 | * Add --debug-dump=links option to readelf and --dwarf=links option to objdump |
82 | which displays the contents of any .gnu_debuglink or .gnu_debugaltlink | |
83 | sections. | |
84 | ||
85 | Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links | |
86 | option to objdump which causes indirect links into separate debug info files | |
87 | to be followed when dumping other DWARF sections. | |
88 | ||

107 | ||
efdf7a02 | 108 | * Add support for the wasm32 ELF conversion of the WebAssembly file format. |
f96bd6c2 | 109 | |
4a14e306 AK |
110 | * Add --inlines option to objdump, which extends the --line-numbers option |
111 | so that inlined functions will display their nesting information. | |
112 | ||
9ef920e9 NC |
113 | * Add --merge-notes options to objcopy to reduce the size of notes in |
114 | a binary file by merging and deleting redundant notes. | |
115 | ||
2425a30e NC |
116 | * Add support for locating separate debug info files using the build-id |
117 | method, where the separate file has a name based upon the build-id of | |
118 | the original file. | |
119 | ||

120 | Changes in 2.28: |
121 | ||
08dc996f AM |
122 | * This version of binutils fixes a problem with PowerPC VLE 16A and 16D |
123 | relocations which were functionally swapped, for example, | |
124 | R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D | |
125 | performed like R_PPC_VLE_HA16A. This could have been fixed by | |
126 | renumbering relocations, which would keep object files created by an | |
127 | older version of gas compatible with a newer ld. However, that would | |
128 | require an ABI update, affecting other assemblers and linkers that | |
129 | create and process the relocations correctly. It is recommended that | |
130 | all VLE object files be recompiled, but ld can modify the relocations | |
a05a5b64 | 131 | if --vle-reloc-fixup is passed to ld. If the new ld command-line |
08dc996f AM |
132 | option is not used, ld will ld warn on finding relocations inconsistent |
133 | with the instructions being relocated. | |
134 | ||
a05a5b64 | 135 | * The nm program has a new command-line option (--with-version-strings) |
df2c87b5 NC |
136 | which will display a symbol's version information, if any, after the |
137 | symbol's name. | |
138 | ||
37fd5ef3 CZ |
139 | * The ARC port of objdump now accepts a -M option to specify the extra |
140 | instruction class(es) that should be disassembled. | |
141 | ||
e511c9b1 AB |
142 | * The --remove-section option for objcopy and strip now accepts section |
143 | patterns starting with an exclamation point to indicate a non-matching | |
144 | section. A non-matching section is removed from the set of sections | |
145 | matched by an earlier --remove-section pattern. | |
146 | ||
147 | * The --only-section option for objcopy now accepts section patterns | |
148 | starting with an exclamation point to indicate a non-matching section. | |
149 | A non-matching section is removed from the set of sections matched by | |
150 | an earlier --only-section pattern. | |
151 | ||
d3e5f6c8 AB |
152 | * New --remove-relocations=SECTIONPATTERN option for objcopy and strip. |
153 | This option can be used to remove sections containing relocations. | |
154 | The SECTIONPATTERN is the section to which the relocations apply, not | |
155 | the relocation section itself. | |
156 | ||
96a84ea3 TG |
157 | Changes in 2.27: |
158 | ||
e6cc316a L |
159 | * Add a configure option, --enable-64-bit-archive, to force use of a |
160 | 64-bit format when creating an archive symbol index. | |
161 | ||
b8871f35 L |
162 | * Add --elf-stt-common= option to objcopy for ELF targets to control |
163 | whether to convert common symbols to the STT_COMMON type. | |
164 | ||
7feec526 TG |
165 | Changes in 2.26: |
166 | ||
2b35fb28 RH |
167 | * Add option to objcopy to insert new symbols into a file: |

ea556d25 L |
172 | * Extend objcopy --compress-debug-sections option to support |
173 | --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF | |
174 | targets. | |
175 | ||
acf1419f AB |

182 | * Add --data option to strings to only print strings in loadable, initialized |
183 | data sections. Change the default behaviour to be --all, but add a new | |
184 | configure time option of --disable-default-strings-all to restore the old | |
185 | default behaviour. | |
186 | ||
334ac421 EA |

213 | passed to preprocessor. | |
44f45767 | 214 | |
fd2f0033 TT |
215 | * Add --dwarf-start and --dwarf-end to readelf and objdump. These are used by |
216 | the new Emacs mode, see dwarf-mode.el. | |
217 | ||
69f56ae1 WL |
218 | * Add support for the Tilera TILEPro and TILE-Gx architectures. |
219 | ||
220 | changes in 2.21: | |
44f45767 | 221 | |
b7dd81f7 NC |
222 | * Add --interleave-width option to objcopy to allowing copying a range of |
223 | bytes from the input to the output with the --interleave option. | |
224 | ||
40b36596 JM |
225 | * Add support for the TMS320C6000 (TI C6X) processor family. |
226 | ||
0b6ae522 DJ |
227 | * Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using |
228 | the -u / --unwind option. | |
229 | ||
2c610e4b L |
230 | * Add --dyn-syms to readelf to dump dynamic symbol table. |
231 | ||
d2420a8c NC |
232 | * A new tool - elfedit - has been added to directly manipulate ELF format |
233 | binaries. | |
81c23f82 | 234 | |
bf201fdd KT |
235 | * Add to dlltool .def file feature of aliasing PE internal symbol name by |
236 | '== <ID>' option. | |
237 | ||
a05a5b64 | 238 | * Add a new command-line option -a / --addresses to addr2line to display the |
be6f6493 TG |
239 | address before function name or source filename. |
240 | ||
a05a5b64 | 241 | * Add a new command-line option -p / --pretty-print to addr2line to have |
68cdf72f TG |
242 | a more human readable output. |
243 | ||
75875724 TG |
244 | * The hppa/som targets can now be compiled on any host. |
245 | ||
81c23f82 TG |
246 | Changes in 2.20: |
247 | ||
10e636d2 DK |
248 | * Add support for delay importing to dlltool. Use the --output-delaylib <file> |
249 | switch to create a delay-import library. The resulting app will load the dll | |
250 | as soon as the first function is called. It will link to __delayLoadHelper2() | |
251 | from the static delayimp library, which will import LoadLibraryA and | |
252 | GetProcAddress from kernel32. | |
253 | ||
a05a5b64 | 254 | * Add a new command-line option, --insn-width=WIDTH, to objdump to specify |
10e636d2 DK |
255 | number of bytes to be displayed on a single line when disassembling |
256 | instructions. | |
3dcb3fcb | 257 | |
cf13d699 | 258 | * Readelf can now display the relocated contents of a section as a sequence |
a05a5b64 | 259 | of bytes via the --relocated-dump=<name|number> command-line option. |
cf13d699 | 260 | |
a05a5b64 | 261 | * The gprof program has been given a new command-line option: |
0e27a8f6 NC |
262 | --external-symbols-table=<filename> which reads in symbols from a specified |
263 | file. | |
6e33da12 | 264 | |
ce3c775b NC |
265 | * The plugin target has been added to bfd. It can load the same shared objects |
266 | used by gold and uses them to provide basic support for new file formats. | |
267 | ||
43cd3ced AG |
268 | * The verilog memory hex dump file format is now supported as an output format |
269 | for objcopy. | |
c067354b | 270 | |
92dd4511 | 271 | * Add --file-alignment, --heap, --image-base, --section-alignment, |
a05a5b64 | 272 | --stack and --subsystem command-line options to objcopy, which will |
92dd4511 L |
273 | set PE optional header. |
274 | ||
4cb93e3b TG |
275 | * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. |
276 | ||
277 | * --as-needed now links in a dynamic library if it satisfies undefined | |
278 | symbols in regular objects, or in other dynamic libraries. In the | |
279 | latter case the library is not linked if it is found in a DT_NEEDED | |
280 | entry of one of the libraries already linked. | |
281 | ||
0dafdf3f | 282 | * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to |
28024d9d | 283 | add absolute paths for -S. |
0dafdf3f | 284 | |
e77b97d4 KT |
285 | * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- |
286 | back to old import table generation with null element prefix. | |
287 | ||
3aade688 | 288 | * Added --identify-strict switch to cause --identify <implib> to |
71c57c16 NC |
289 | report an error when the import library is associated with |
290 | multiple DLLs. | |
291 | ||
292 | * Added --identify <implib> option to dlltool, which determines the | |
293 | name of the DLL associated with the specified <implib>. | |
294 | ||
2f3bb96a BE |
295 | * Support for PowerPC booke64 instructions has been removed. The assembler no |
296 | longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts | |
297 | -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. | |
298 | ||
6e33da12 TG |
299 | Changes in 2.19: |
300 | ||
a262ae96 NC |
301 | * Added -wL switch to dump decoded contents of .debug_line. |
302 | ||
a8da6403 NC |
303 | * Added support for "thin" archives which contain pathnames pointing to |
304 | object files rather than the files themselves and which contain a | |
305 | flattened symbol index for all objects, and archives, which have been | |
306 | added to the archive. | |
3aade688 | 307 | |
98ec6e72 NC |
308 | * Added -F switch to objdump to include file offsets in the disassembly. |
309 | ||
4145f1d5 NC |
310 | * Added -c switch to readelf to allow string dumps of archive symbol index. |
311 | ||
85f10a01 MM |
312 | * Support for SSE5 has been added to the i386 port. |
313 | ||
09c11c86 NC |
314 | * Added -p switch to readelf to allow string dumps of sections. |
315 | ||
876c34bf | 316 | Changes in 2.18: |
98ec6e72 | 317 | |
ad71ef64 NC |
318 | * Resolved 37 coding problems in bfd including static array overruns, null |
319 | pointer dereferences and use of a malloc buffer after it has been freed, as | |
320 | revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). | |
1e4cf259 | 321 | |
32866df7 NC |
322 | * The binutils sources are now released under version 3 of the GNU General |
323 | Public License. | |
324 | ||
692ed3e7 NC |
325 | * A new tool "windmc" has been added for some targets. This is a message |
326 | compiler which attempts to be compatible with the MS version. | |
327 | ||
328 | * Add codepage support to the windres tool. It now supports many new | |
329 | resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation | |
330 | for binary files is done now via bfd itself. The endianess problems | |
331 | for different hosts are solved. Dumps of .res files can now be | |
332 | re-compiled by windres without lossing resources or compilation errors. | |
333 | Some problems on dialog resource translations are corrected. | |
d856f2dd | 334 | |
a05a5b64 | 335 | * Add --extract-symbol command-line option to objcopy, which will |
d3e52d40 RS |
336 | strip everything out of an ordinary object file or executable except |
337 | for its symbol table. Files containing just symbols can be useful | |
338 | to some OSes. | |
339 | ||
32866df7 NC |
340 | Changes in 2.17: |
341 | ||
aef1f6d0 DJ |
342 | * Add "-x NAME" to readelf in addition to "-x NUMBER". |
343 | ||
cbf1f5df NC |
344 | * Add -i and -t switches to cxxfilt. -i disables the display of implementation |
345 | specific extra demangling information (if any) and -t disables the demangling | |
346 | of types. | |
347 | ||
348 | * Add support for the "@<file>" syntax to the command lines of all tools, so | |
349 | that extra switches can be read from <file>. | |
350 | ||
4de2ad99 | 351 | * Add "-W/--dwarf" to objdump to display the contents of the DWARF |
cbf1f5df | 352 | debug sections. |
4de2ad99 | 353 | |
5477e8a0 | 354 | * Add "-t/--section-details" to readelf to display section details. |
cbf1f5df | 355 | "-N/--full-section-name" is deprecated. |
5477e8a0 | 356 | |
b12fe839 AM |
357 | * powerpc-linux ld now supports a variant form of PLT and GOT for the security |
358 | conscious. This form will automatically be chosen when ld detects that all | |
359 | code in regular object files was generated by gcc -msecure-plt. The old PLT | |
360 | and GOT may be forced by a new ld option, --bss-plt. | |
361 | ||
0c552dc1 FF |
362 | * Add "-i/--inlines" to addr2line to print enclosing scope information |
363 | for inlined function chains, back to first non-inlined function. | |
364 | ||
81fc812e L |
365 | * Add "-N/--full-section-name" to readelf to display full section name. |
366 | ||
ec72cfe5 NC |
367 | * Add "-M entry:<addr>" switch to objdump to specify a function entry address |
368 | when disassembling VAX binaries. | |
369 | ||
7b4a0685 NC |
370 | * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches |
371 | to objcopy to convert local symbols into global symbols. | |
3aade688 | 372 | |
9fbad737 | 373 | * gprof now allows input files to have histogram records for |
3aade688 | 374 | several memory ranges, provided those ranges are disjoint. |
7b4a0685 NC |
375 | |
376 | Changes in 2.16: | |
377 | ||
b12fe839 | 378 | * Add "-g/--section-groups" to readelf to display section groups. |
81fc812e | 379 | |
bcf32829 JB |
380 | * objcopy recognizes two new options --strip-unneeded-symbol and |
381 | --strip-unneeded-symbols, namely for use together with the wildcard | |
382 | matching the original --strip-symbol/--strip-symbols provided, but | |
383 | retaining any symbols matching but needed by relocations. | |
384 | ||
18bd398b NC |
385 | * readelf can now display address ranges from .debug_range sections. This |
386 | happens automatically when a DW_AT_range attribute is encountered. The | |
a05a5b64 | 387 | command-line switch --debug-dump=Ranges (or -wR) can also be used to display |
18bd398b NC |
388 | the contents of the .debug_range section. |
389 | ||
3c9458e9 NC |
390 | * nm and objdump now have a switch "--special-syms" to enable the displaying of |
391 | symbols which the target considers to be special. By default these symbols | |
392 | are no longer displayed. Currently the only special symbols are the Mapping | |
393 | symbols used by the ARM port to mark transitions between text and data and | |
394 | between ARM and THUMB code. | |
395 | ||
607dea97 NC |
396 | * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional |
397 | import and export symbols with <preifx> prepended to them. | |
398 | ||
399 | Changes in 2.15: | |
400 | ||
e39893d7 | 401 | * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the |
9d317d34 | 402 | disassembler to print the "raw" mips instruction mnemonic instead of some |
e39893d7 FF |
403 | pseudo instruction name. I.E. print "daddu" or "or" instead of "move", |
404 | "sll" instead of "nop", etc. | |
405 | ||
5fe11841 NC |
406 | * objcopy and strip can now take wildcard patterns in symbol names specified on |
407 | the command line provided that the --wildcard switch is used to enable them. | |
408 | ||
fb52b2f4 NC |
409 | * readelf can now parse archives. |
410 | ||
51cdc6e0 NC |
411 | * objdump now accepts --debugging-tags to print the debug information in a |
412 | format compatible with ctags tool. | |
413 | ||
ed1653a7 NC |
414 | * objcopy and strip now accept --only-keep-debug to create a file containing |
415 | those sections that would be stripped out by --strip-debug. The idea is that | |
416 | this can be used in conjunction with the --add-gnu-debuglink switch to create | |
417 | a two part program distribution - one a stripped executable and the other the | |
418 | debugging info. | |
419 | ||
2593f09a NC |
420 | * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink |
421 | section into a (presumably stripped) executable. This allows the debug | |
50c2245b | 422 | information for the file to be held in a separate file. |
3aade688 | 423 | |
a3b6428f NC |
424 | * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX |
425 | single-character representation. This can be checked by running nm | |
426 | with the -a switch. | |
427 | ||
43c58ae6 CD |
428 | Changes in 2.14: |
429 | ||
7c29036b NC |
430 | * Added --info switch to objcopy and strip. |
431 | ||
3b36097d SC |
432 | * Support for Vitesse IQ2000 added by Red Hat. |
433 | ||
8745eafa NC |
434 | * Added 'S' encoding to strings to allow the display of 8-bit characters. |
435 | ||
d7fb0dd2 NC |
436 | * Added --prefix-symbols=<text>, --prefix-sections=<text> and |
437 | --prefix-alloc-sections=<text> to objcopy. | |
438 | ||
84ad6ede NC |
439 | * readelf can handle the extensions to the DWARF2 spec used by the Unified |
440 | Parallel C compiler. | |
441 | ||
7d036af2 AM |
442 | * BFD no longer declares a "boolean" type, to avoid clashes with other |
443 | headers that declare the same. Users of BFD should replace boolean, | |
444 | false and true, with int, 0 and 1, or define their own boolean type. | |
445 | ||
1e4cf259 NC |
446 | * Support for IP2K added by Denis Chertykov. |
447 | ||
2cbb2eef NC |
448 | Changes in 2.13: |
449 | ||
450 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 | |
451 | and FR500 included. | |
252b5132 | 452 | |
9a66911f NC |
453 | Changes in version 2.12: |
454 | ||
49fda6c8 HPN |
455 | * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
456 | ||
15c82623 NC |
457 | * size: Add --totals to display summary of sizes (Berkeley format only). |
458 | ||
d974e256 JJ |
459 | * readelf: Add --wide option to not break section header or segment listing |
460 | lines to fit into 80 columns. | |
461 | ||
d132876a NC |
462 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
463 | ||
594ef5db NC |
464 | * objcopy: Add --rename-section to change section names. |
465 | ||
e0c60db2 NC |
466 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
467 | displaying the contents of .debug.macinfo sections. | |
468 | ||
a05a5b64 | 469 | * New command-line switches added to objcopy to allow symbols to be kept as |
16b2b71c NC |
470 | global symbols, and also to specify files containing lists of such symbols. |
471 | by Honda Hiroki. | |
472 | ||
87e6d782 NC |
473 | * Support for OpenRISC by Johan Rydberg. |
474 | ||
a05a5b64 | 475 | * New command-line switch to objcopy --alt-machine-code which creates a binary |
1ae8b3d2 AO |
476 | with an alternate machine code if one is defined in the architecture |
477 | description. Only supported for ELF targets. By Alexandre Oliva. | |
478 | ||
a05a5b64 | 479 | * New command-line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 480 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
481 | makes sense, if the input target is binary. Otherwise it is ignored. |
482 | By Stefan Geuken. | |
483 | ||
e135f41b NC |
484 | * Support for PDP-11 by Lars Brinkhoff. |
485 | ||
09ad7db3 AM |
486 | Changes in binutils 2.11: |
487 | ||
077b8428 NC |
488 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
489 | extenstions. | |
490 | ||
a05a5b64 | 491 | * Add --srec-len and --srec-forceS3 command-line switch to objcopy. |
077b8428 | 492 | By Luciano Gemme. |
7d036af2 | 493 | |
156c2f8b NC |
494 | * Support for the MIPS32, by Anders Norlander. |
495 | ||
22b36938 JE |
496 | * Support for the i860, by Jason Eckhardt. |
497 | ||
5bcac8a4 HPN |
498 | * Support for CRIS (Axis Communications ETRAX series). |
499 | ||
252b5132 RH |
500 | Changes in binutils 2.10: |
501 | ||
09ad7db3 AM |
502 | * Support for 64-bit ELF on HPPA. |
503 | ||
a05a5b64 | 504 | * New command-line switch to objdump --file-start-context which shows the |
f1563258 | 505 | entire file contents up to the source line first encountered for a given |
7d036af2 | 506 | file. |
f1563258 | 507 | |
a05a5b64 | 508 | * New command-line switch to objdump -M (or --disassembler-options) which takes |
dd92f639 NC |
509 | a parameter which can then be interpreted on a per-target basis by the |
510 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
511 | raw verions. | |
7d036af2 | 512 | |
c2c40d93 ILT |
513 | * objdump support for -mi386:intel which causes disassembly to be displayed |
514 | with intel syntax. | |
252b5132 RH |
515 | |
516 | * New program: readelf. This displays the contents of ELF format files, | |
517 | regardless of target machine. | |
518 | ||
519 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
520 | --change-section-address options. The old --adjust-section-vma option is | |
521 | equivalent to --change-section-address. The other --adjust-* options are now | |
522 | renamed to --change-*, although --adjust-* continues to work. | |
523 | ||
57938635 AM |
524 | * objcopy has a --redefine-sym option that lets you rename symbols. |
525 | ||
526 | * objcopy now takes a -j/--only-section option to copy only the specified | |
527 | sections. | |
528 | ||
252b5132 RH |
529 | * dlltool now supports the IMPORTS command. |
530 | ||
531 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
532 | --exclude-symbols, and --no-default-excludes options. | |
533 | ||
534 | Changes in binutils 2.9: | |
535 | ||
536 | * Added windres program, which can be used to manipulate resources in WIN32 | |
537 | files as used on Windows 95 and Windows NT. | |
538 | ||
539 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
540 | the VMA of the sections. | |
541 | ||
542 | * Added S modifier to ar to not build a symbol table. | |
543 | ||
544 | Changes in binutils 2.8: | |
545 | ||
546 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
547 | the new --prefix-addresses option to get the old format. There are also new | |
548 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
549 | output. | |
550 | ||
551 | * Formats may now be specified as configuration triplets. For example, | |
552 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
553 | so they must be in canonical form. | |
554 | ||
555 | * Added new addr2line program. This uses the debugging information to convert | |
556 | an address into a file name and line number within a program. | |
557 | ||
558 | * Added --change-leading-char argument to objcopy. | |
559 | ||
560 | * Added --weaken argument to objcopy. | |
561 | ||
562 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
563 | ||
564 | * Added --adjust-vma option to objdump. | |
565 | ||
566 | * Added -C/--demangle option to objdump. | |
567 | ||
568 | * Added -p/--preserve-dates option to strip and objcopy. | |
569 | ||
570 | Changes in binutils 2.7: | |
571 | ||
572 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
573 | ||
574 | * Added --debugging argument to objdump and objcopy. | |
575 | ||
576 | * Added --defined-only argument to nm. | |
577 | ||
578 | * Added --remove-leading-char argument to objcopy. | |
579 | ||
580 | * The objdump --line-numbers option is now meaningful with --reloc. | |
581 | ||
582 | * Added --line-numbers option to nm. | |
583 | ||
584 | * Added --endian/-EB/-EL option to objdump. | |
585 | ||
586 | * Added support for Alpha OpenVMS/AXP. | |
587 | ||
588 | Changes in binutils 2.6: | |
589 | ||
590 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
591 | ||
592 | * Added several arguments to objcopy to provide some control over how the new | |
593 | file is laid out in memory. Also added binary output format to BFD to permit | |
594 | generating plain binary files. | |
595 | ||
596 | * Added --start-address and --stop-address options to objdump. | |
597 | ||
598 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
599 | ||
600 | Changes in binutils 2.5: | |
601 | ||
602 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
1049f94e | 603 | listing, for a more useful listing of relocatable files. |
252b5132 RH |
604 | |
605 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
606 | Added -D/--disassemble-all option to disassemble all sections. | |
607 | ||
608 | * Added --size-sort option to nm. | |
609 | ||
610 | * strip and objcopy should now be able to handle dynamically linked ELF | |
611 | executables. | |
612 | ||
613 | Changes in binutils 2.4: | |
614 | ||
615 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
616 | PowerPC (except ar and ranlib; by Ian Taylor). | |
617 | ||
618 | * Support for Irix 5. | |
619 | ||
620 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
621 | ELF output files, since BFD currently can't create them properly. | |
622 | ||
623 | Changes in binutils 2.3: | |
624 | ||
625 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
626 | ELF and COFF files. | |
627 | ||
628 | * A new program, nlmconv, has been added. It can convert object files into | |
629 | Novell NetWare Loadable Modules. | |
630 | ||
631 | * The strings program has been added. | |
632 | ||
633 | Changes in binutils 2.2: | |
634 | ||
635 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
636 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
637 | 'cp'. | |
638 | ||
639 | * The new stand-alone program c++filt is a filter that converts encoded | |
640 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
641 | may get moved to the gcc distribution.) | |
642 | ||
643 | * nm -o on an archive now prefixes each line with the archive name, matching | |
644 | the output from BSD nm. | |
645 | ||
646 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
647 | ||
648 | * New support for H8500, Z8000, and the Hitach SH. | |
649 | ||
650 | * Dis-assembler interface changed to allow sharing with gdb. | |
651 | ||
652 | * There is new Elf code, but it is not yet ready for general use. | |
653 | ||
654 | * There is the beginnings of a test suite. | |
655 | ||
656 | Changes in binutils 2.1: | |
657 | ||
658 | * There is now support for writing ECOFF files, so ld and the other utilities | |
659 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
660 | ||
661 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
662 | version), if there are any object files in the archive. So running ranlib is | |
663 | now redundant (unless the non-standard q command is used). This is required | |
664 | for Posix.2 conformance. | |
665 | ||
666 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
667 | independently of the selected target format. This is to encourage people to | |
668 | switch to SYSV-format, which has a number of advantages. | |
669 | ||
670 | * The strip and copy programs now have options to remove debug-symbols only | |
671 | and/or local symbols only. They now also support long options. | |
672 | ||
