2 Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 and
3 FR500 included.

5 Changes in version 2.12:
6
7 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
8
9 * size: Add --totals to display summary of sizes (Berkeley format only).
10
11 * readelf: Add --wide option to not break section header or segment listing
12 lines to fit into 80 columns.
13
14 * strings: Add --encoding to display wide character strings. By Markus Kuhn.
15
16 * objcopy: Add --rename-section to change section names.
17
18 * readelf: Support added for DWARF 2.1 extensions. Support added for
19 displaying the contents of .debug.macinfo sections.
20
21 * New command line switches added to objcopy to allow symbols to be kept as
22 global symbols, and also to specify files containing lists of such symbols.
23 by Honda Hiroki.
24
25 * Support for OpenRISC by Johan Rydberg.
26
27 * New command line switch to objcopy --alt-machine-code which creates a binary
28 with an alternate machine code if one is defined in the architecture
29 description. Only supported for ELF targets. By Alexandre Oliva.
30
31 * New command line switch to objcopy -B (or --binary-architecture) which sets
32 the architecture of the output file to the given argument. This option only
33 makes sense, if the input target is binary. Otherwise it is ignored.
34 By Stefan Geuken.
35
36 * Support for PDP-11 by Lars Brinkhoff.
37
38 Changes in binutils 2.11:
39
40 * Add support for ARM v5t and v5te architectures and Intel's XScale ARM
41 extenstions.
42
43 * Add --srec-len and --srec-forceS3 command line switch to objcopy.
44 By Luciano Gemme.
45
46 * Support for the MIPS32, by Anders Norlander.
47
48 * Support for the i860, by Jason Eckhardt.
49
50 * Support for CRIS (Axis Communications ETRAX series).
51
52 Changes in binutils 2.10:
53
54 * Support for 64-bit ELF on HPPA.
55
56 * New command line switch to objdump --file-start-context which shows the
57 entire file contents up to the source line first encountered for a given
58 file.
59
60 * New command line switch to objdump -M (or --disassembler-options) which takes
61 a parameter which can then be interpreted on a per-target basis by the
62 disassembler. Used by ARM targets to select register name sets, ISA, APCS or
63 raw verions.
64
65 * objdump support for -mi386:intel which causes disassembly to be displayed
66 with intel syntax.
67
68 * New program: readelf. This displays the contents of ELF format files,
69 regardless of target machine.
70
71 * objcopy now takes --change-section-lma, --change-section-vma, and
72 --change-section-address options. The old --adjust-section-vma option is
73 equivalent to --change-section-address. The other --adjust-* options are now
74 renamed to --change-*, although --adjust-* continues to work.
75
76 * objcopy has a --redefine-sym option that lets you rename symbols.
77
78 * objcopy now takes a -j/--only-section option to copy only the specified
79 sections.
80
81 * dlltool now supports the IMPORTS command.
82
83 * dlltool now takes --export-all-symbols, --no-export-all-symbols,
84 --exclude-symbols, and --no-default-excludes options.
85
86 Changes in binutils 2.9:
87
88 * Added windres program, which can be used to manipulate resources in WIN32
89 files as used on Windows 95 and Windows NT.
90
91 * The objcopy --gap-fill and --pad-to options operate on the LMA rather than
92 the VMA of the sections.
93
94 * Added S modifier to ar to not build a symbol table.
95
96 Changes in binutils 2.8:
97
98 * The objdump disassembly format has been changed, and hopefully improved. Use
99 the new --prefix-addresses option to get the old format. There are also new
100 --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
101 output.
102
103 * Formats may now be specified as configuration triplets. For example,
104 objdump -b i386-pc-linux. The triplets are not passed through config.sub,
105 so they must be in canonical form.
106
107 * Added new addr2line program. This uses the debugging information to convert
108 an address into a file name and line number within a program.
109
110 * Added --change-leading-char argument to objcopy.
111
112 * Added --weaken argument to objcopy.
113
114 * objdump --dynamic-reloc now works on ELF executables and shared libraries.
115
116 * Added --adjust-vma option to objdump.
117
118 * Added -C/--demangle option to objdump.
119
120 * Added -p/--preserve-dates option to strip and objcopy.
121
122 Changes in binutils 2.7:
123
124 * Added --enable-shared and --enable-commonbfdlib options to configure.
125
126 * Added --debugging argument to objdump and objcopy.
127
128 * Added --defined-only argument to nm.
129
130 * Added --remove-leading-char argument to objcopy.
131
132 * The objdump --line-numbers option is now meaningful with --reloc.
133
134 * Added --line-numbers option to nm.
135
136 * Added --endian/-EB/-EL option to objdump.
137
138 * Added support for Alpha OpenVMS/AXP.
139
140 Changes in binutils 2.6:
141
142 * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
143
144 * Added several arguments to objcopy to provide some control over how the new
145 file is laid out in memory. Also added binary output format to BFD to permit
146 generating plain binary files.
147
148 * Added --start-address and --stop-address options to objdump.
149
150 * ar and ranlib now work on AIX. The tools are now built by default on AIX.
151
152 Changes in binutils 2.5:
153
154 * Changed objdump -dr to dump the relocs interspersed with the assembly
155 listing, for a more useful listing of relocateable files.
156
157 * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
158 Added -D/--disassemble-all option to disassemble all sections.
159
160 * Added --size-sort option to nm.
161
162 * strip and objcopy should now be able to handle dynamically linked ELF
163 executables.
164
165 Changes in binutils 2.4:
166
167 * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
168 PowerPC (except ar and ranlib; by Ian Taylor).
169
170 * Support for Irix 5.
171
172 * Programs `strip' and `objcopy' will not attempt to write dynamically linked
173 ELF output files, since BFD currently can't create them properly.
174
175 Changes in binutils 2.3:
176
177 * A new --stabs argument has been added to objdump to dump stabs sections in
178 ELF and COFF files.
179
180 * A new program, nlmconv, has been added. It can convert object files into
181 Novell NetWare Loadable Modules.
182
183 * The strings program has been added.
184
185 Changes in binutils 2.2:
186
187 * The 'copy' program has been renamed to 'objcopy', for consistency with
188 'objdump', and because 'copy' might more plausibly be used as a synonym for
189 'cp'.
190
191 * The new stand-alone program c++filt is a filter that converts encoded
192 (mangled) C++ assembly-level identifiers to user-level names. (Note: This
193 may get moved to the gcc distribution.)
194
195 * nm -o on an archive now prefixes each line with the archive name, matching
196 the output from BSD nm.
197
198 * ar (and ld) can now read (but not write) BSD4.4-style archives.
199
200 * New support for H8500, Z8000, and the Hitach SH.
201
202 * Dis-assembler interface changed to allow sharing with gdb.
203
204 * There is new Elf code, but it is not yet ready for general use.
205
206 * There is the beginnings of a test suite.
207
208 Changes in binutils 2.1:
209
210 * There is now support for writing ECOFF files, so ld and the other utilities
211 should work on Risc/Ultrix and Irix. Please let us know how well this works.
212
213 * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
214 version), if there are any object files in the archive. So running ranlib is
215 now redundant (unless the non-standard q command is used). This is required
216 for Posix.2 conformance.
217
218 * The archive-reading code now reads both BSD-style and SYSV-style archives
219 independently of the selected target format. This is to encourage people to
220 switch to SYSV-format, which has a number of advantages.
221
222 * The strip and copy programs now have options to remove debug-symbols only
223 and/or local symbols only. They now also support long options.
