3 | * objcopy: Add --rename-section to change section names. |
4 | ||
e0c60db2 NC |
5 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
6 | displaying the contents of .debug.macinfo sections. | |
7 | ||
16b2b71c NC |
8 | * New command line switches added to objcopy to allow symbols to be kept as |
9 | global symbols, and also to specify files containing lists of such symbols. | |
10 | by Honda Hiroki. | |

87e6d782 NC |
12 | * Support for OpenRISC by Johan Rydberg. |
13 | ||
43a0748c | 14 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
09ad7db3 | 15 | the architecture of the output file to the given argument. This option only |
43a0748c NC |
16 | makes sense, if the input target is binary. Otherwise it is ignored. |

22 | ||
077b8428 NC |
23 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
24 | extenstions. | |
25 | ||
26 | * Add --srec-len and --srec-forceS3 command line switch to objcopy. | |

29 | * Support for the MIPS32, by Anders Norlander. |
30 | ||
22b36938 JE |
31 | * Support for the i860, by Jason Eckhardt. |
32 | ||
5bcac8a4 HPN |
33 | * Support for CRIS (Axis Communications ETRAX series). |
34 | ||

35 | Changes in binutils 2.10: |
36 | ||
09ad7db3 AM |
37 | * Support for 64-bit ELF on HPPA. |
38 | ||
f1563258 TW |
39 | * New command line switch to objdump --file-start-context which shows the |
40 | entire file contents up to the source line first encountered for a given | |
41 | file. | |
42 | ||
dd92f639 NC |
43 | * New command line switch to objdump -M (or --disassembler-options) which takes |
44 | a parameter which can then be interpreted on a per-target basis by the | |
45 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
46 | raw verions. | |
47 | ||
c2c40d93 ILT |
48 | * objdump support for -mi386:intel which causes disassembly to be displayed |
49 | with intel syntax. | |
252b5132 RH |
50 | |
51 | * New program: readelf. This displays the contents of ELF format files, | |
52 | regardless of target machine. | |
53 | ||
54 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
55 | --change-section-address options. The old --adjust-section-vma option is | |
56 | equivalent to --change-section-address. The other --adjust-* options are now | |
57 | renamed to --change-*, although --adjust-* continues to work. | |
58 | ||
57938635 AM |
59 | * objcopy has a --redefine-sym option that lets you rename symbols. |
60 | ||
61 | * objcopy now takes a -j/--only-section option to copy only the specified | |
62 | sections. | |
63 | ||
252b5132 RH |
64 | * dlltool now supports the IMPORTS command. |
65 | ||
66 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
67 | --exclude-symbols, and --no-default-excludes options. | |
68 | ||
69 | Changes in binutils 2.9: | |
70 | ||
71 | * Added windres program, which can be used to manipulate resources in WIN32 | |
72 | files as used on Windows 95 and Windows NT. | |
73 | ||
74 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
75 | the VMA of the sections. | |
76 | ||
77 | * Added S modifier to ar to not build a symbol table. | |
78 | ||
79 | Changes in binutils 2.8: | |
80 | ||
81 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
82 | the new --prefix-addresses option to get the old format. There are also new | |
83 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
84 | output. | |
85 | ||
86 | * Formats may now be specified as configuration triplets. For example, | |
87 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
88 | so they must be in canonical form. | |
89 | ||
90 | * Added new addr2line program. This uses the debugging information to convert | |
91 | an address into a file name and line number within a program. | |
92 | ||
93 | * Added --change-leading-char argument to objcopy. | |
94 | ||
95 | * Added --weaken argument to objcopy. | |
96 | ||
97 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
98 | ||
99 | * Added --adjust-vma option to objdump. | |
100 | ||
101 | * Added -C/--demangle option to objdump. | |
102 | ||
103 | * Added -p/--preserve-dates option to strip and objcopy. | |
104 | ||
105 | Changes in binutils 2.7: | |
106 | ||
107 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
108 | ||
109 | * Added --debugging argument to objdump and objcopy. | |
110 | ||
111 | * Added --defined-only argument to nm. | |
112 | ||
113 | * Added --remove-leading-char argument to objcopy. | |
114 | ||
115 | * The objdump --line-numbers option is now meaningful with --reloc. | |
116 | ||
117 | * Added --line-numbers option to nm. | |
118 | ||
119 | * Added --endian/-EB/-EL option to objdump. | |
120 | ||
121 | * Added support for Alpha OpenVMS/AXP. | |
122 | ||
123 | Changes in binutils 2.6: | |
124 | ||
125 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
126 | ||
127 | * Added several arguments to objcopy to provide some control over how the new | |
128 | file is laid out in memory. Also added binary output format to BFD to permit | |
129 | generating plain binary files. | |
130 | ||
131 | * Added --start-address and --stop-address options to objdump. | |
132 | ||
133 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
134 | ||
135 | Changes in binutils 2.5: | |
136 | ||
137 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
138 | listing, for a more useful listing of relocateable files. | |
139 | ||
140 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
141 | Added -D/--disassemble-all option to disassemble all sections. | |
142 | ||
143 | * Added --size-sort option to nm. | |
144 | ||
145 | * strip and objcopy should now be able to handle dynamically linked ELF | |
146 | executables. | |
147 | ||
148 | Changes in binutils 2.4: | |
149 | ||
150 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
151 | PowerPC (except ar and ranlib; by Ian Taylor). | |
152 | ||
153 | * Support for Irix 5. | |
154 | ||
155 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
156 | ELF output files, since BFD currently can't create them properly. | |
157 | ||
158 | Changes in binutils 2.3: | |
159 | ||
160 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
161 | ELF and COFF files. | |
162 | ||
163 | * A new program, nlmconv, has been added. It can convert object files into | |
164 | Novell NetWare Loadable Modules. | |
165 | ||
166 | * The strings program has been added. | |
167 | ||
168 | Changes in binutils 2.2: | |
169 | ||
170 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
171 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
172 | 'cp'. | |
173 | ||
174 | * The new stand-alone program c++filt is a filter that converts encoded | |
175 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
176 | may get moved to the gcc distribution.) | |
177 | ||
178 | * nm -o on an archive now prefixes each line with the archive name, matching | |
179 | the output from BSD nm. | |
180 | ||
181 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
182 | ||
183 | * New support for H8500, Z8000, and the Hitach SH. | |
184 | ||
185 | * Dis-assembler interface changed to allow sharing with gdb. | |
186 | ||
187 | * There is new Elf code, but it is not yet ready for general use. | |
188 | ||
189 | * There is the beginnings of a test suite. | |
190 | ||
191 | Changes in binutils 2.1: | |
192 | ||
193 | * There is now support for writing ECOFF files, so ld and the other utilities | |
194 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
195 | ||
196 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
197 | version), if there are any object files in the archive. So running ranlib is | |
198 | now redundant (unless the non-standard q command is used). This is required | |
199 | for Posix.2 conformance. | |
200 | ||
201 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
202 | independently of the selected target format. This is to encourage people to | |
203 | switch to SYSV-format, which has a number of advantages. | |
204 | ||
205 | * The strip and copy programs now have options to remove debug-symbols only | |
206 | and/or local symbols only. They now also support long options. | |
