3 | * objcopy recognizes two new options --strip-unneeded-symbol and |
4 | --strip-unneeded-symbols, namely for use together with the wildcard | |
5 | matching the original --strip-symbol/--strip-symbols provided, but | |
6 | retaining any symbols matching but needed by relocations. | |

8 | * readelf can now display address ranges from .debug_range sections. This |
9 | happens automatically when a DW_AT_range attribute is encountered. The | |
10 | command line switch --debug-dump=Ranges (or -wR) can also be used to display | |
11 | the contents of the .debug_range section. | |
12 | ||
3c9458e9 NC |
13 | * nm and objdump now have a switch "--special-syms" to enable the displaying of |
14 | symbols which the target considers to be special. By default these symbols | |
15 | are no longer displayed. Currently the only special symbols are the Mapping | |
16 | symbols used by the ARM port to mark transitions between text and data and | |
17 | between ARM and THUMB code. | |
18 | ||
607dea97 NC |
19 | * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional |
20 | import and export symbols with <preifx> prepended to them. | |
21 | ||
22 | Changes in 2.15: | |
23 | ||
5fe11841 NC |
24 | * objcopy and strip can now take wildcard patterns in symbol names specified on |
25 | the command line provided that the --wildcard switch is used to enable them. | |
26 | ||
fb52b2f4 NC |
27 | * readelf can now parse archives. |
28 | ||
51cdc6e0 NC |
29 | * objdump now accepts --debugging-tags to print the debug information in a |
30 | format compatible with ctags tool. | |
31 | ||
ed1653a7 NC |
32 | * objcopy and strip now accept --only-keep-debug to create a file containing |
33 | those sections that would be stripped out by --strip-debug. The idea is that | |
34 | this can be used in conjunction with the --add-gnu-debuglink switch to create | |
35 | a two part program distribution - one a stripped executable and the other the | |
36 | debugging info. | |
37 | ||
2593f09a NC |
38 | * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink |
39 | section into a (presumably stripped) executable. This allows the debug | |
50c2245b | 40 | information for the file to be held in a separate file. |
2593f09a | 41 | |
a3b6428f NC |
42 | * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX |
43 | single-character representation. This can be checked by running nm | |
44 | with the -a switch. | |

51 | ||
8745eafa NC |
52 | * Added 'S' encoding to strings to allow the display of 8-bit characters. |
53 | ||
d7fb0dd2 NC |
54 | * Added --prefix-symbols=<text>, --prefix-sections=<text> and |
55 | --prefix-alloc-sections=<text> to objcopy. | |
56 | ||
84ad6ede NC |
57 | * readelf can handle the extensions to the DWARF2 spec used by the Unified |
58 | Parallel C compiler. | |
59 | ||
7d036af2 AM |
60 | * BFD no longer declares a "boolean" type, to avoid clashes with other |
61 | headers that declare the same. Users of BFD should replace boolean, | |
62 | false and true, with int, 0 and 1, or define their own boolean type. | |
63 | ||
1e4cf259 NC |
64 | * Support for IP2K added by Denis Chertykov. |
65 | ||
2cbb2eef NC |
66 | Changes in 2.13: |
67 | ||
68 | * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 | |
69 | and FR500 included. | |

76 | ||
d974e256 JJ |
77 | * readelf: Add --wide option to not break section header or segment listing |
78 | lines to fit into 80 columns. | |
79 | ||
d132876a NC |
80 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
81 | ||

82 | * objcopy: Add --rename-section to change section names. |
83 | ||
e0c60db2 NC |
84 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
85 | displaying the contents of .debug.macinfo sections. | |
86 | ||
16b2b71c NC |
87 | * New command line switches added to objcopy to allow symbols to be kept as |
88 | global symbols, and also to specify files containing lists of such symbols. | |
89 | by Honda Hiroki. | |
90 | ||
87e6d782 NC |
91 | * Support for OpenRISC by Johan Rydberg. |
92 | ||
1ae8b3d2 AO |
93 | * New command line switch to objcopy --alt-machine-code which creates a binary |
94 | with an alternate machine code if one is defined in the architecture | |
95 | description. Only supported for ELF targets. By Alexandre Oliva. | |
96 | ||
43a0748c | 97 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 98 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
99 | makes sense, if the input target is binary. Otherwise it is ignored. |

118 | Changes in binutils 2.10: |
119 | ||
09ad7db3 AM |
120 | * Support for 64-bit ELF on HPPA. |
121 | ||
f1563258 TW |
122 | * New command line switch to objdump --file-start-context which shows the |
123 | entire file contents up to the source line first encountered for a given | |
7d036af2 | 124 | file. |
f1563258 | 125 | |
dd92f639 NC |
126 | * New command line switch to objdump -M (or --disassembler-options) which takes |
127 | a parameter which can then be interpreted on a per-target basis by the | |
128 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
129 | raw verions. | |
7d036af2 | 130 | |
c2c40d93 ILT |
131 | * objdump support for -mi386:intel which causes disassembly to be displayed |
132 | with intel syntax. | |
252b5132 RH |
133 | |
134 | * New program: readelf. This displays the contents of ELF format files, | |
135 | regardless of target machine. | |
136 | ||
137 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
138 | --change-section-address options. The old --adjust-section-vma option is | |
139 | equivalent to --change-section-address. The other --adjust-* options are now | |
140 | renamed to --change-*, although --adjust-* continues to work. | |
141 | ||
57938635 AM |
142 | * objcopy has a --redefine-sym option that lets you rename symbols. |
143 | ||
144 | * objcopy now takes a -j/--only-section option to copy only the specified | |
145 | sections. | |
146 | ||
252b5132 RH |
147 | * dlltool now supports the IMPORTS command. |
148 | ||
149 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
150 | --exclude-symbols, and --no-default-excludes options. | |
151 | ||
152 | Changes in binutils 2.9: | |
153 | ||
154 | * Added windres program, which can be used to manipulate resources in WIN32 | |
155 | files as used on Windows 95 and Windows NT. | |
156 | ||
157 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
158 | the VMA of the sections. | |
159 | ||
160 | * Added S modifier to ar to not build a symbol table. | |
161 | ||
162 | Changes in binutils 2.8: | |
163 | ||
164 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
165 | the new --prefix-addresses option to get the old format. There are also new | |
166 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
167 | output. | |
168 | ||
169 | * Formats may now be specified as configuration triplets. For example, | |
170 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
171 | so they must be in canonical form. | |
172 | ||
173 | * Added new addr2line program. This uses the debugging information to convert | |
174 | an address into a file name and line number within a program. | |
175 | ||
176 | * Added --change-leading-char argument to objcopy. | |
177 | ||
178 | * Added --weaken argument to objcopy. | |
179 | ||
180 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
181 | ||
182 | * Added --adjust-vma option to objdump. | |
183 | ||
184 | * Added -C/--demangle option to objdump. | |
185 | ||
186 | * Added -p/--preserve-dates option to strip and objcopy. | |
187 | ||
188 | Changes in binutils 2.7: | |
189 | ||
190 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
191 | ||
192 | * Added --debugging argument to objdump and objcopy. | |
193 | ||
194 | * Added --defined-only argument to nm. | |
195 | ||
196 | * Added --remove-leading-char argument to objcopy. | |
197 | ||
198 | * The objdump --line-numbers option is now meaningful with --reloc. | |
199 | ||
200 | * Added --line-numbers option to nm. | |
201 | ||
202 | * Added --endian/-EB/-EL option to objdump. | |
203 | ||
204 | * Added support for Alpha OpenVMS/AXP. | |
205 | ||
206 | Changes in binutils 2.6: | |
207 | ||
208 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
209 | ||
210 | * Added several arguments to objcopy to provide some control over how the new | |
211 | file is laid out in memory. Also added binary output format to BFD to permit | |
212 | generating plain binary files. | |
213 | ||
214 | * Added --start-address and --stop-address options to objdump. | |
215 | ||
216 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
217 | ||
218 | Changes in binutils 2.5: | |
219 | ||
220 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
1049f94e | 221 | listing, for a more useful listing of relocatable files. |
252b5132 RH |
222 | |
223 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
224 | Added -D/--disassemble-all option to disassemble all sections. | |
225 | ||
226 | * Added --size-sort option to nm. | |
227 | ||
228 | * strip and objcopy should now be able to handle dynamically linked ELF | |
229 | executables. | |
230 | ||
231 | Changes in binutils 2.4: | |
232 | ||
233 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
234 | PowerPC (except ar and ranlib; by Ian Taylor). | |
235 | ||
236 | * Support for Irix 5. | |
237 | ||
238 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
239 | ELF output files, since BFD currently can't create them properly. | |
240 | ||
241 | Changes in binutils 2.3: | |
242 | ||
243 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
244 | ELF and COFF files. | |
245 | ||
246 | * A new program, nlmconv, has been added. It can convert object files into | |
247 | Novell NetWare Loadable Modules. | |
248 | ||
249 | * The strings program has been added. | |
250 | ||
251 | Changes in binutils 2.2: | |
252 | ||
253 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
254 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
255 | 'cp'. | |
256 | ||
257 | * The new stand-alone program c++filt is a filter that converts encoded | |
258 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
259 | may get moved to the gcc distribution.) | |
260 | ||
261 | * nm -o on an archive now prefixes each line with the archive name, matching | |
262 | the output from BSD nm. | |
263 | ||
264 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
265 | ||
266 | * New support for H8500, Z8000, and the Hitach SH. | |
267 | ||
268 | * Dis-assembler interface changed to allow sharing with gdb. | |
269 | ||
270 | * There is new Elf code, but it is not yet ready for general use. | |
271 | ||
272 | * There is the beginnings of a test suite. | |
273 | ||
274 | Changes in binutils 2.1: | |
275 | ||
276 | * There is now support for writing ECOFF files, so ld and the other utilities | |
277 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
278 | ||
279 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
280 | version), if there are any object files in the archive. So running ranlib is | |
281 | now redundant (unless the non-standard q command is used). This is required | |
282 | for Posix.2 conformance. | |
283 | ||
284 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
285 | independently of the selected target format. This is to encourage people to | |
286 | switch to SYSV-format, which has a number of advantages. | |
287 | ||
288 | * The strip and copy programs now have options to remove debug-symbols only | |
289 | and/or local symbols only. They now also support long options. | |
