2
* Added -wL switch to dump decoded contents of .debug_line.
3
 
4
* Added support for "thin" archives which contain pathnames pointing to
5
  object files rather than the files themselves and which contain a
6
  flattened symbol index for all objects, and archives, which have been
7
  added to the archive.
8
 
9
* Added -F switch to objdump to include file offsets in the disassembly.
10
 
11
* Added -c switch to readelf to allow string dumps of archive symbol index.
12
 
13
* Support for SSE5 has been added to the i386 port.
14
 
15
* Added -p switch to readelf to allow string dumps of sections.
16
 
17
Changes in 2.18:
18
 
19
* Resolved 37 coding problems in bfd including static array overruns, null
20
  pointer dereferences and use of a malloc buffer after it has been freed, as
21
  revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com).
22
 
23
* The binutils sources are now released under version 3 of the GNU General
24
  Public License.
25
 
26
* A new tool "windmc" has been added for some targets.  This is a message
27
  compiler which attempts to be compatible with the MS version.
28
 
29
* Add codepage support to the windres tool.  It now supports many new
30
  resource types (e.g. MANIFEST, TOOLBAR, etc).  The output generation
31
  for binary files is done now via bfd itself.  The endianess problems
32
  for different hosts are solved.  Dumps of .res files can now be
33
  re-compiled by windres without lossing resources or compilation errors.
34
  Some problems on dialog resource translations are corrected.
35
 
36
* Add --extract-symbol command line option to objcopy, which will
37
  strip everything out of an ordinary object file or executable except
38
  for its symbol table.  Files containing just symbols can be useful
39
  to some OSes.
40
 
41
Changes in 2.17:
42
 
43
* Add "-x NAME" to readelf in addition to "-x NUMBER".
44
 
45
* Add -i and -t switches to cxxfilt.  -i disables the display of implementation
46
  specific extra demangling information (if any) and -t disables the demangling
47
  of types.
48
 
49
* Add support for the "@" syntax to the command lines of all tools, so
50
  that extra switches can be read from .
51
 
52
* Add "-W/--dwarf" to objdump to display the contents of the DWARF
53
  debug sections.
54
 
55
* Add "-t/--section-details" to readelf to display section details.
56
  "-N/--full-section-name" is deprecated.
57
 
58
* powerpc-linux ld now supports a variant form of PLT and GOT for the security
59
  conscious.  This form will automatically be chosen when ld detects that all
60
  code in regular object files was generated by gcc -msecure-plt.  The old PLT
61
  and GOT may be forced by a new ld option, --bss-plt.
62
 
63
* Add "-i/--inlines" to addr2line to print enclosing scope information
64
  for inlined function chains, back to first non-inlined function.
65
 
66
* Add "-N/--full-section-name" to readelf to display full section name.
67
 
68
* Add "-M entry:" switch to objdump to specify a function entry address
69
  when disassembling VAX binaries.
70
 
71
* Add "--globalize-symbol " and "--globalize-symbols " switches
72
  to objcopy to convert local symbols into global symbols.
73
 
74
* gprof now allows input files to have histogram records for
75
  several memory ranges, provided those ranges are disjoint.
76
 
77
Changes in 2.16:
78
 
79
* Add "-g/--section-groups" to readelf to display section groups.
80
 
81
* objcopy recognizes two new options --strip-unneeded-symbol and
82
  --strip-unneeded-symbols, namely for use together with the wildcard
83
  matching the original --strip-symbol/--strip-symbols provided, but
84
  retaining any symbols matching but needed by relocations.
85
 
86
* readelf can now display address ranges from .debug_range sections.  This
87
  happens automatically when a DW_AT_range attribute is encountered.  The
88
  command line switch --debug-dump=Ranges (or -wR) can also be used to display
89
  the contents of the .debug_range section.
90
 
91
* nm and objdump now have a switch "--special-syms" to enable the displaying of
92
  symbols which the target considers to be special.  By default these symbols
93
  are no longer displayed.  Currently the only special symbols are the Mapping
94
  symbols used by the ARM port to mark transitions between text and data and
95
  between ARM and THUMB code.
96
 
97
* dlltool has a switch "--ext-prefix-alias " to generate additional
98
  import and export symbols with  prepended to them.
99
 
100
Changes in 2.15:
101
 
102
* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
103
  disassembler to print the "raw" mips instruction mnemonic instead of some
104
  pseudo instruction name.  I.E. print "daddu" or "or" instead of "move",
105
  "sll" instead of "nop", etc.
106
 
107
* objcopy and strip can now take wildcard patterns in symbol names specified on
108
  the command line provided that the --wildcard switch is used to enable them.
109
 
110
* readelf can now parse archives.
111
 
112
* objdump now accepts --debugging-tags to print the debug information in a
113
  format compatible with ctags tool.
114
 
115
* objcopy and strip now accept --only-keep-debug to create a file containing
116
  those sections that would be stripped out by --strip-debug.  The idea is that
117
  this can be used in conjunction with the --add-gnu-debuglink switch to create
118
  a two part program distribution - one a stripped executable and the other the
119
  debugging info.
120
 
121
* objcopy now accepts --add-gnu-debuglink= to insert a .gnu_debuglink
122
  section into a (presumably stripped) executable.  This allows the debug
123
  information for the file to be held in a separate file.
124
 
125
* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
126
  single-character representation.  This can be checked by running nm
127
  with the -a switch.
128
 
129
Changes in 2.14:
130
 
131
* Added --info switch to objcopy and strip.
132
 
133
* Support for Vitesse IQ2000 added by Red Hat.
134
 
135
* Added 'S' encoding to strings to allow the display of 8-bit characters.
136
 
137
* Added --prefix-symbols=, --prefix-sections= and
138
  --prefix-alloc-sections= to objcopy.
139
 
140
* readelf can handle the extensions to the DWARF2 spec used by the Unified
141
  Parallel C compiler.
142
 
143
* BFD no longer declares a "boolean" type, to avoid clashes with other
144
  headers that declare the same.  Users of BFD should replace boolean,
145
  false and true, with int, 0 and 1, or define their own boolean type.
146
 
147
* Support for IP2K added by Denis Chertykov.
148
 
149
Changes in 2.13:
150
 
151
* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
152
  and FR500 included.
153
 
154
Changes in version 2.12:
155
 
156
* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
157
 
158
* size: Add --totals to display summary of sizes (Berkeley format only).
159
 
160
* readelf: Add --wide option to not break section header or segment listing
161
  lines to fit into 80 columns.
162
 
163
* strings: Add --encoding to display wide character strings.  By Markus Kuhn.
164
 
165
* objcopy: Add --rename-section to change section names.
166
 
167
* readelf: Support added for DWARF 2.1 extensions.  Support added for
168
  displaying the contents of .debug.macinfo sections.
169
 
170
* New command line switches added to objcopy to allow symbols to be kept as
171
  global symbols, and also to specify files containing lists of such symbols.
172
  by Honda Hiroki.
173
 
174
* Support for OpenRISC by Johan Rydberg.
175
 
176
* New command line switch to objcopy --alt-machine-code which creates a binary
177
  with an alternate machine code if one is defined in the architecture
178
  description.  Only supported for ELF targets.  By Alexandre Oliva.
179
 
180
* New command line switch to objcopy -B (or --binary-architecture) which sets
181
  the architecture of the output file to the given argument.  This option only
182
  makes sense, if the input target is binary.  Otherwise it is ignored.
183
  By Stefan Geuken.
184
 
185
* Support for PDP-11 by Lars Brinkhoff.
186
 
187
Changes in binutils 2.11:
188
 
189
* Add support for ARM v5t and v5te architectures and Intel's XScale ARM
190
  extenstions.
191
 
192
* Add --srec-len and --srec-forceS3 command line switch to objcopy.
193
  By Luciano Gemme.
194
 
195
* Support for the MIPS32, by Anders Norlander.
196
 
197
* Support for the i860, by Jason Eckhardt.
198
 
199
* Support for CRIS (Axis Communications ETRAX series).
200
 
201
Changes in binutils 2.10:
202
 
203
* Support for 64-bit ELF on HPPA.
204
 
205
* New command line switch to objdump --file-start-context which shows the
206
  entire file contents up to the source line first encountered for a given
207
  file.
208
 
209
* New command line switch to objdump -M (or --disassembler-options) which takes
210
  a parameter which can then be interpreted on a per-target basis by the
211
  disassembler.  Used by ARM targets to select register name sets, ISA, APCS or
212
  raw verions.
213
 
214
* objdump support for -mi386:intel which causes disassembly to be displayed
215
  with intel syntax.
216
 
217
* New program: readelf.  This displays the contents of ELF format files,
218
  regardless of target machine.
219
 
220
* objcopy now takes --change-section-lma, --change-section-vma, and
221
  --change-section-address options.  The old --adjust-section-vma option is
222
  equivalent to --change-section-address.  The other --adjust-* options are now
223
  renamed to --change-*, although --adjust-* continues to work.
224
 
225
* objcopy has a --redefine-sym option that lets you rename symbols.
226
 
227
* objcopy now takes a -j/--only-section option to copy only the specified
228
  sections.
229
 
230
* dlltool now supports the IMPORTS command.
231
 
232
* dlltool now takes --export-all-symbols, --no-export-all-symbols,
233
  --exclude-symbols, and --no-default-excludes options.
234
 
235
Changes in binutils 2.9:
236
 
237
* Added windres program, which can be used to manipulate resources in WIN32
238
  files as used on Windows 95 and Windows NT.
239
 
240
* The objcopy --gap-fill and --pad-to options operate on the LMA rather than
241
  the VMA of the sections.
242
 
243
* Added S modifier to ar to not build a symbol table.
244
 
245
Changes in binutils 2.8:
246
 
247
* The objdump disassembly format has been changed, and hopefully improved.  Use
248
  the new --prefix-addresses option to get the old format.  There are also new
249
  --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
250
  output.
251
 
252
* Formats may now be specified as configuration triplets.  For example,
253
  objdump -b i386-pc-linux.  The triplets are not passed through config.sub,
254
  so they must be in canonical form.
255
 
256
* Added new addr2line program.  This uses the debugging information to convert
257
  an address into a file name and line number within a program.
258
 
259
* Added --change-leading-char argument to objcopy.
260
 
261
* Added --weaken argument to objcopy.
262
 
263
* objdump --dynamic-reloc now works on ELF executables and shared libraries.
264
 
265
* Added --adjust-vma option to objdump.
266
 
267
* Added -C/--demangle option to objdump.
268
 
269
* Added -p/--preserve-dates option to strip and objcopy.
270
 
271
Changes in binutils 2.7:
272
 
273
* Added --enable-shared and --enable-commonbfdlib options to configure.
274
 
275
* Added --debugging argument to objdump and objcopy.
276
 
277
* Added --defined-only argument to nm.
278
 
279
* Added --remove-leading-char argument to objcopy.
280
 
281
* The objdump --line-numbers option is now meaningful with --reloc.
282
 
283
* Added --line-numbers option to nm.
284
 
285
* Added --endian/-EB/-EL option to objdump.
286
 
287
* Added support for Alpha OpenVMS/AXP.
288
 
289
Changes in binutils 2.6:
290
 
291
* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
292
 
293
* Added several arguments to objcopy to provide some control over how the new
294
  file is laid out in memory.  Also added binary output format to BFD to permit
295
  generating plain binary files.
296
 
297
* Added --start-address and --stop-address options to objdump.
298
 
299
* ar and ranlib now work on AIX.  The tools are now built by default on AIX.
300
 
301
Changes in binutils 2.5:
302
 
303
* Changed objdump -dr to dump the relocs interspersed with the assembly
304
  listing, for a more useful listing of relocatable files.
305
 
306
* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
307
  Added -D/--disassemble-all option to disassemble all sections.
308
 
309
* Added --size-sort option to nm.
310
 
311
* strip and objcopy should now be able to handle dynamically linked ELF
312
  executables.
313
 
314
Changes in binutils 2.4:
315
 
316
* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
317
  PowerPC (except ar and ranlib; by Ian Taylor).
318
 
319
* Support for Irix 5.
320
 
321
* Programs `strip' and `objcopy' will not attempt to write dynamically linked
322
  ELF output files, since BFD currently can't create them properly.
323
 
324
Changes in binutils 2.3:
325
 
326
* A new --stabs argument has been added to objdump to dump stabs sections in
327
  ELF and COFF files.
328
 
329
* A new program, nlmconv, has been added.  It can convert object files into
330
  Novell NetWare Loadable Modules.
331
 
332
* The strings program has been added.
333
 
334
Changes in binutils 2.2:
335
 
336
* The 'copy' program has been renamed to 'objcopy', for consistency with
337
  'objdump', and because 'copy' might more plausibly be used as a synonym for
338
  'cp'.
339
 
340
* The new stand-alone program c++filt is a filter that converts encoded
341
  (mangled) C++ assembly-level identifiers to user-level names.  (Note: This
342
  may get moved to the gcc distribution.)
343
 
344
* nm -o on an archive now prefixes each line with the archive name, matching
345
  the output from BSD nm.
346
 
347
* ar (and ld) can now read (but not write) BSD4.4-style archives.
348
 
349
* New support for H8500, Z8000, and the Hitach SH.
350
 
351
* Dis-assembler interface changed to allow sharing with gdb.
352
 
353
* There is new Elf code, but it is not yet ready for general use.
354
 
355
* There is the beginnings of a test suite.
356
 
357
Changes in binutils 2.1:
358
 
359
* There is now support for writing ECOFF files, so ld and the other utilities
360
  should work on Risc/Ultrix and Irix.  Please let us know how well this works.
361
 
362
* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
363
  version), if there are any object files in the archive.  So running ranlib is
364
  now redundant (unless the non-standard q command is used).  This is required
365
  for Posix.2 conformance.
366
 
367
* The archive-reading code now reads both BSD-style and SYSV-style archives
368
  independently of the selected target format.  This is to encourage people to
369
  switch to SYSV-format, which has a number of advantages.
370
 
371
* The strip and copy programs now have options to remove debug-symbols only
372
  and/or local symbols only.  They now also support long options.
373
