3 | * readelf can handle the extensions to the DWARF2 spec used by the Unified |
4 | Parallel C compiler. | |
5 | ||
7d036af2 AM |
6 | * BFD no longer declares a "boolean" type, to avoid clashes with other |
7 | headers that declare the same. Users of BFD should replace boolean, | |
8 | false and true, with int, 0 and 1, or define their own boolean type. | |

22 | ||
d974e256 JJ |
23 | * readelf: Add --wide option to not break section header or segment listing |
24 | lines to fit into 80 columns. | |
25 | ||
d132876a NC |
26 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |

594ef5db NC |
28 | * objcopy: Add --rename-section to change section names. |
29 | ||
e0c60db2 NC |
30 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
31 | displaying the contents of .debug.macinfo sections. | |
32 | ||
16b2b71c NC |
33 | * New command line switches added to objcopy to allow symbols to be kept as |
34 | global symbols, and also to specify files containing lists of such symbols. | |

39 | * New command line switch to objcopy --alt-machine-code which creates a binary |
40 | with an alternate machine code if one is defined in the architecture | |
41 | description. Only supported for ELF targets. By Alexandre Oliva. | |
42 | ||
43a0748c | 43 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 44 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
45 | makes sense, if the input target is binary. Otherwise it is ignored. |

64 | Changes in binutils 2.10: |
65 | ||
09ad7db3 AM |
66 | * Support for 64-bit ELF on HPPA. |
67 | ||
f1563258 TW |
68 | * New command line switch to objdump --file-start-context which shows the |
69 | entire file contents up to the source line first encountered for a given | |
7d036af2 | 70 | file. |
f1563258 | 71 | |
dd92f639 NC |
72 | * New command line switch to objdump -M (or --disassembler-options) which takes |
73 | a parameter which can then be interpreted on a per-target basis by the | |
74 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
75 | raw verions. | |
7d036af2 | 76 | |
c2c40d93 ILT |
77 | * objdump support for -mi386:intel which causes disassembly to be displayed |
78 | with intel syntax. | |
252b5132 RH |
79 | |
80 | * New program: readelf. This displays the contents of ELF format files, | |
81 | regardless of target machine. | |
82 | ||
83 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
84 | --change-section-address options. The old --adjust-section-vma option is | |
85 | equivalent to --change-section-address. The other --adjust-* options are now | |
86 | renamed to --change-*, although --adjust-* continues to work. | |
87 | ||
57938635 AM |
88 | * objcopy has a --redefine-sym option that lets you rename symbols. |
89 | ||
90 | * objcopy now takes a -j/--only-section option to copy only the specified | |
91 | sections. | |
92 | ||
252b5132 RH |
93 | * dlltool now supports the IMPORTS command. |
94 | ||
95 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
96 | --exclude-symbols, and --no-default-excludes options. | |
97 | ||
98 | Changes in binutils 2.9: | |
99 | ||
100 | * Added windres program, which can be used to manipulate resources in WIN32 | |
101 | files as used on Windows 95 and Windows NT. | |
102 | ||
103 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
104 | the VMA of the sections. | |
105 | ||
106 | * Added S modifier to ar to not build a symbol table. | |
107 | ||
108 | Changes in binutils 2.8: | |
109 | ||
110 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
111 | the new --prefix-addresses option to get the old format. There are also new | |
112 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
113 | output. | |
114 | ||
115 | * Formats may now be specified as configuration triplets. For example, | |
116 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
117 | so they must be in canonical form. | |
118 | ||
119 | * Added new addr2line program. This uses the debugging information to convert | |
120 | an address into a file name and line number within a program. | |
121 | ||
122 | * Added --change-leading-char argument to objcopy. | |
123 | ||
124 | * Added --weaken argument to objcopy. | |
125 | ||
126 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
127 | ||
128 | * Added --adjust-vma option to objdump. | |
129 | ||
130 | * Added -C/--demangle option to objdump. | |
131 | ||
132 | * Added -p/--preserve-dates option to strip and objcopy. | |
133 | ||
134 | Changes in binutils 2.7: | |
135 | ||
136 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
137 | ||
138 | * Added --debugging argument to objdump and objcopy. | |
139 | ||
140 | * Added --defined-only argument to nm. | |
141 | ||
142 | * Added --remove-leading-char argument to objcopy. | |
143 | ||
144 | * The objdump --line-numbers option is now meaningful with --reloc. | |
145 | ||
146 | * Added --line-numbers option to nm. | |
147 | ||
148 | * Added --endian/-EB/-EL option to objdump. | |
149 | ||
150 | * Added support for Alpha OpenVMS/AXP. | |
151 | ||
152 | Changes in binutils 2.6: | |
153 | ||
154 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
155 | ||
156 | * Added several arguments to objcopy to provide some control over how the new | |
157 | file is laid out in memory. Also added binary output format to BFD to permit | |
158 | generating plain binary files. | |
159 | ||
160 | * Added --start-address and --stop-address options to objdump. | |
161 | ||
162 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
163 | ||
164 | Changes in binutils 2.5: | |
165 | ||
166 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
167 | listing, for a more useful listing of relocateable files. | |
168 | ||
169 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
170 | Added -D/--disassemble-all option to disassemble all sections. | |
171 | ||
172 | * Added --size-sort option to nm. | |
173 | ||
174 | * strip and objcopy should now be able to handle dynamically linked ELF | |
175 | executables. | |
176 | ||
177 | Changes in binutils 2.4: | |
178 | ||
179 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
180 | PowerPC (except ar and ranlib; by Ian Taylor). | |
181 | ||
182 | * Support for Irix 5. | |
183 | ||
184 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
185 | ELF output files, since BFD currently can't create them properly. | |
186 | ||
187 | Changes in binutils 2.3: | |
188 | ||
189 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
190 | ELF and COFF files. | |
191 | ||
192 | * A new program, nlmconv, has been added. It can convert object files into | |
193 | Novell NetWare Loadable Modules. | |
194 | ||
195 | * The strings program has been added. | |
196 | ||
197 | Changes in binutils 2.2: | |
198 | ||
199 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
200 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
201 | 'cp'. | |
202 | ||
203 | * The new stand-alone program c++filt is a filter that converts encoded | |
204 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
205 | may get moved to the gcc distribution.) | |
206 | ||
207 | * nm -o on an archive now prefixes each line with the archive name, matching | |
208 | the output from BSD nm. | |
209 | ||
210 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
211 | ||
212 | * New support for H8500, Z8000, and the Hitach SH. | |
213 | ||
214 | * Dis-assembler interface changed to allow sharing with gdb. | |
215 | ||
216 | * There is new Elf code, but it is not yet ready for general use. | |
217 | ||
218 | * There is the beginnings of a test suite. | |
219 | ||
220 | Changes in binutils 2.1: | |
221 | ||
222 | * There is now support for writing ECOFF files, so ld and the other utilities | |
223 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
224 | ||
225 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
226 | version), if there are any object files in the archive. So running ranlib is | |
227 | now redundant (unless the non-standard q command is used). This is required | |
228 | for Posix.2 conformance. | |
229 | ||
230 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
231 | independently of the selected target format. This is to encourage people to | |
232 | switch to SYSV-format, which has a number of advantages. | |
233 | ||
234 | * The strip and copy programs now have options to remove debug-symbols only | |
235 | and/or local symbols only. They now also support long options. | |
