3 | * New command line switches added to objcopy to allow symbols to be kept as |
4 | global symbols, and also to specify files containing lists of such symbols. | |
5 | by Honda Hiroki. | |
6 | ||
87e6d782 NC |
7 | * Support for OpenRISC by Johan Rydberg. |
8 | ||
43a0748c NC |
9 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
10 | the archiceture of the output file to the given argument. This option only | |
11 | makes sense, if the input target is binary. Otherwise it is ignored. | |
12 | By Stefan Geuken. | |

14 | * Support for PDP-11 by Lars Brinkhoff. |
15 | ||
077b8428 NC |
16 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
17 | extenstions. | |
18 | ||
19 | * Add --srec-len and --srec-forceS3 command line switch to objcopy. | |

24 | * Support for the i860, by Jason Eckhardt. |

28 | Changes in binutils 2.10: |
29 | ||
f1563258 TW |
30 | * New command line switch to objdump --file-start-context which shows the |
31 | entire file contents up to the source line first encountered for a given | |
32 | file. | |
33 | ||
dd92f639 NC |
34 | * New command line switch to objdump -M (or --disassembler-options) which takes |
35 | a parameter which can then be interpreted on a per-target basis by the | |
36 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
37 | raw verions. | |
38 | ||
c2c40d93 ILT |
39 | * objdump support for -mi386:intel which causes disassembly to be displayed |
40 | with intel syntax. | |
252b5132 RH |
41 | |
42 | * New program: readelf. This displays the contents of ELF format files, | |
43 | regardless of target machine. | |
44 | ||
45 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
46 | --change-section-address options. The old --adjust-section-vma option is | |
47 | equivalent to --change-section-address. The other --adjust-* options are now | |
48 | renamed to --change-*, although --adjust-* continues to work. | |
49 | ||
57938635 AM |
50 | * objcopy has a --redefine-sym option that lets you rename symbols. |
51 | ||
52 | * objcopy now takes a -j/--only-section option to copy only the specified | |
53 | sections. | |
54 | ||
252b5132 RH |
55 | * dlltool now supports the IMPORTS command. |
56 | ||
57 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
58 | --exclude-symbols, and --no-default-excludes options. | |
59 | ||
60 | Changes in binutils 2.9: | |
61 | ||
62 | * Added windres program, which can be used to manipulate resources in WIN32 | |
63 | files as used on Windows 95 and Windows NT. | |
64 | ||
65 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
66 | the VMA of the sections. | |
67 | ||
68 | * Added S modifier to ar to not build a symbol table. | |
69 | ||
70 | Changes in binutils 2.8: | |
71 | ||
72 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
73 | the new --prefix-addresses option to get the old format. There are also new | |
74 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
75 | output. | |
76 | ||
77 | * Formats may now be specified as configuration triplets. For example, | |
78 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
79 | so they must be in canonical form. | |
80 | ||
81 | * Added new addr2line program. This uses the debugging information to convert | |
82 | an address into a file name and line number within a program. | |
83 | ||
84 | * Added --change-leading-char argument to objcopy. | |
85 | ||
86 | * Added --weaken argument to objcopy. | |
87 | ||
88 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
89 | ||
90 | * Added --adjust-vma option to objdump. | |
91 | ||
92 | * Added -C/--demangle option to objdump. | |
93 | ||
94 | * Added -p/--preserve-dates option to strip and objcopy. | |
95 | ||
96 | Changes in binutils 2.7: | |
97 | ||
98 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
99 | ||
100 | * Added --debugging argument to objdump and objcopy. | |
101 | ||
102 | * Added --defined-only argument to nm. | |
103 | ||
104 | * Added --remove-leading-char argument to objcopy. | |
105 | ||
106 | * The objdump --line-numbers option is now meaningful with --reloc. | |
107 | ||
108 | * Added --line-numbers option to nm. | |
109 | ||
110 | * Added --endian/-EB/-EL option to objdump. | |
111 | ||
112 | * Added support for Alpha OpenVMS/AXP. | |
113 | ||
114 | Changes in binutils 2.6: | |
115 | ||
116 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
117 | ||
118 | * Added several arguments to objcopy to provide some control over how the new | |
119 | file is laid out in memory. Also added binary output format to BFD to permit | |
120 | generating plain binary files. | |
121 | ||
122 | * Added --start-address and --stop-address options to objdump. | |
123 | ||
124 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
125 | ||
126 | Changes in binutils 2.5: | |
127 | ||
128 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
129 | listing, for a more useful listing of relocateable files. | |
130 | ||
131 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
132 | Added -D/--disassemble-all option to disassemble all sections. | |
133 | ||
134 | * Added --size-sort option to nm. | |
135 | ||
136 | * strip and objcopy should now be able to handle dynamically linked ELF | |
137 | executables. | |
138 | ||
139 | Changes in binutils 2.4: | |
140 | ||
141 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
142 | PowerPC (except ar and ranlib; by Ian Taylor). | |
143 | ||
144 | * Support for Irix 5. | |
145 | ||
146 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
147 | ELF output files, since BFD currently can't create them properly. | |
148 | ||
149 | Changes in binutils 2.3: | |
150 | ||
151 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
152 | ELF and COFF files. | |
153 | ||
154 | * A new program, nlmconv, has been added. It can convert object files into | |
155 | Novell NetWare Loadable Modules. | |
156 | ||
157 | * The strings program has been added. | |
158 | ||
159 | Changes in binutils 2.2: | |
160 | ||
161 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
162 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
163 | 'cp'. | |
164 | ||
165 | * The new stand-alone program c++filt is a filter that converts encoded | |
166 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
167 | may get moved to the gcc distribution.) | |
168 | ||
169 | * nm -o on an archive now prefixes each line with the archive name, matching | |
170 | the output from BSD nm. | |
171 | ||
172 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
173 | ||
174 | * New support for H8500, Z8000, and the Hitach SH. | |
175 | ||
176 | * Dis-assembler interface changed to allow sharing with gdb. | |
177 | ||
178 | * There is new Elf code, but it is not yet ready for general use. | |
179 | ||
180 | * There is the beginnings of a test suite. | |
181 | ||
182 | Changes in binutils 2.1: | |
183 | ||
184 | * There is now support for writing ECOFF files, so ld and the other utilities | |
185 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
186 | ||
187 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
188 | version), if there are any object files in the archive. So running ranlib is | |
189 | now redundant (unless the non-standard q command is used). This is required | |
190 | for Posix.2 conformance. | |
191 | ||
192 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
193 | independently of the selected target format. This is to encourage people to | |
194 | switch to SYSV-format, which has a number of advantages. | |
195 | ||
196 | * The strip and copy programs now have options to remove debug-symbols only | |
197 | and/or local symbols only. They now also support long options. | |
