3
* Add --preprocessor-arg option to windres to specify additional options
4
  passed to preprocessor.
5
 
6
* Add --dwarf-start and --dwarf-end to readelf and objdump.  These are used by
7
  the new Emacs mode, see dwarf-mode.el.
8
 
9
Changes in 2.21:
10
 
11
* Add --interleave-width option to objcopy to allowing copying a range of
12
  bytes from the input to the output with the --interleave option.
13
 
14
* Add support for the TMS320C6000 (TI C6X) processor family.
15
 
16
* Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using
17
  the -u / --unwind option.
18
 
19
* Add --dyn-syms to readelf to dump dynamic symbol table.
20
 
21
* A new tool - elfedit - has been added to directly manipulate ELF format
22
  binaries.
23
 
24
* Add to dlltool .def file feature of aliasing PE internal symbol name by
25
  '== ' option.
26
 
27
* Add a new command line option -a / --addresses to addr2line to display the
28
  address before function name or source filename.
29
 
30
* Add a new command line option -p / --pretty-print to addr2line to have
31
  a more human readable output.
32
 
33
* The hppa/som targets can now be compiled on any host.
34
 
35
Changes in 2.20:
36
 
37
* Add support for delay importing to dlltool.  Use the --output-delaylib 
38
  switch to create a delay-import library.  The resulting app will load the dll
39
  as soon as the first function is called.  It will link to __delayLoadHelper2()
40
  from the static delayimp library, which will import LoadLibraryA and
41
  GetProcAddress from kernel32.
42
 
43
* Add a new command line option, --insn-width=WIDTH, to objdump to specify
44
  number of bytes to be displayed on a single line when disassembling
45
  instructions.
46
 
47
* Readelf can now display the relocated contents of a section as a sequence
48
  of bytes via the --relocated-dump= command line option.
49
 
50
* The gprof program has been given a new command line option:
51
  --external-symbols-table= which reads in symbols from a specified
52
  file.
53
 
54
* The plugin target has been added to bfd. It can load the same shared objects
55
  used by gold and uses them to provide basic support for new file formats.
56
 
57
* The verilog memory hex dump file format is now supported as an output format
58
  for objcopy.
59
 
60
* Add --file-alignment, --heap, --image-base, --section-alignment,
61
  --stack and --subsystem command line options to objcopy, which will
62
  set PE optional header.
63
 
64
* Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w.
65
 
66
* --as-needed now links in a dynamic library if it satisfies undefined
67
  symbols in regular objects, or in other dynamic libraries.  In the
68
  latter case the library is not linked if it is found in a DT_NEEDED
69
  entry of one of the libraries already linked.
70
 
71
* Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to
72
  add absolute paths for -S.
73
 
74
* Add new option --use-nul-prefixed-import-tables to dlltool to allow fall-
75
  back to old import table generation with null element prefix.
76
 
77
* Added --identify-strict switch to cause --identify  to
78
  report an error when the import library is associated with
79
  multiple DLLs.
80
 
81
* Added --identify  option to dlltool, which determines the
82
  name of the DLL associated with the specified .
83
 
84
* Support for PowerPC booke64 instructions has been removed.  The assembler no
85
  longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts
86
  -Mbooke32 or -Mbooke64.  Instead, -mbooke and -Mbooke should be used.
87
 
88
Changes in 2.19:
89
 
90
* Added -wL switch to dump decoded contents of .debug_line.
91
 
92
* Added support for "thin" archives which contain pathnames pointing to
93
  object files rather than the files themselves and which contain a
94
  flattened symbol index for all objects, and archives, which have been
95
  added to the archive.
96
 
97
* Added -F switch to objdump to include file offsets in the disassembly.
98
 
99
* Added -c switch to readelf to allow string dumps of archive symbol index.
100
 
101
* Support for SSE5 has been added to the i386 port.
102
 
103
* Added -p switch to readelf to allow string dumps of sections.
104
 
105
Changes in 2.18:
106
 
107
* Resolved 37 coding problems in bfd including static array overruns, null
108
  pointer dereferences and use of a malloc buffer after it has been freed, as
109
  revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com).
110
 
111
* The binutils sources are now released under version 3 of the GNU General
112
  Public License.
113
 
114
* A new tool "windmc" has been added for some targets.  This is a message
115
  compiler which attempts to be compatible with the MS version.
116
 
117
* Add codepage support to the windres tool.  It now supports many new
118
  resource types (e.g. MANIFEST, TOOLBAR, etc).  The output generation
119
  for binary files is done now via bfd itself.  The endianess problems
120
  for different hosts are solved.  Dumps of .res files can now be
121
  re-compiled by windres without lossing resources or compilation errors.
122
  Some problems on dialog resource translations are corrected.
123
 
124
* Add --extract-symbol command line option to objcopy, which will
125
  strip everything out of an ordinary object file or executable except
126
  for its symbol table.  Files containing just symbols can be useful
127
  to some OSes.
128
 
129
Changes in 2.17:
130
 
131
* Add "-x NAME" to readelf in addition to "-x NUMBER".
132
 
133
* Add -i and -t switches to cxxfilt.  -i disables the display of implementation
134
  specific extra demangling information (if any) and -t disables the demangling
135
  of types.
136
 
137
* Add support for the "@" syntax to the command lines of all tools, so
138
  that extra switches can be read from .
139
 
140
* Add "-W/--dwarf" to objdump to display the contents of the DWARF
141
  debug sections.
142
 
143
* Add "-t/--section-details" to readelf to display section details.
144
  "-N/--full-section-name" is deprecated.
145
 
146
* powerpc-linux ld now supports a variant form of PLT and GOT for the security
147
  conscious.  This form will automatically be chosen when ld detects that all
148
  code in regular object files was generated by gcc -msecure-plt.  The old PLT
149
  and GOT may be forced by a new ld option, --bss-plt.
150
 
151
* Add "-i/--inlines" to addr2line to print enclosing scope information
152
  for inlined function chains, back to first non-inlined function.
153
 
154
* Add "-N/--full-section-name" to readelf to display full section name.
155
 
156
* Add "-M entry:" switch to objdump to specify a function entry address
157
  when disassembling VAX binaries.
158
 
159
* Add "--globalize-symbol " and "--globalize-symbols " switches
160
  to objcopy to convert local symbols into global symbols.
161
 
162
* gprof now allows input files to have histogram records for
163
  several memory ranges, provided those ranges are disjoint.
164
 
165
Changes in 2.16:
166
 
167
* Add "-g/--section-groups" to readelf to display section groups.
168
 
169
* objcopy recognizes two new options --strip-unneeded-symbol and
170
  --strip-unneeded-symbols, namely for use together with the wildcard
171
  matching the original --strip-symbol/--strip-symbols provided, but
172
  retaining any symbols matching but needed by relocations.
173
 
174
* readelf can now display address ranges from .debug_range sections.  This
175
  happens automatically when a DW_AT_range attribute is encountered.  The
176
  command line switch --debug-dump=Ranges (or -wR) can also be used to display
177
  the contents of the .debug_range section.
178
 
179
* nm and objdump now have a switch "--special-syms" to enable the displaying of
180
  symbols which the target considers to be special.  By default these symbols
181
  are no longer displayed.  Currently the only special symbols are the Mapping
182
  symbols used by the ARM port to mark transitions between text and data and
183
  between ARM and THUMB code.
184
 
185
* dlltool has a switch "--ext-prefix-alias " to generate additional
186
  import and export symbols with  prepended to them.
187
 
188
Changes in 2.15:
189
 
190
* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
191
  disassembler to print the "raw" mips instruction mnemonic instead of some
192
  pseudo instruction name.  I.E. print "daddu" or "or" instead of "move",
193
  "sll" instead of "nop", etc.
194
 
195
* objcopy and strip can now take wildcard patterns in symbol names specified on
196
  the command line provided that the --wildcard switch is used to enable them.
197
 
198
* readelf can now parse archives.
199
 
200
* objdump now accepts --debugging-tags to print the debug information in a
201
  format compatible with ctags tool.
202
 
203
* objcopy and strip now accept --only-keep-debug to create a file containing
204
  those sections that would be stripped out by --strip-debug.  The idea is that
205
  this can be used in conjunction with the --add-gnu-debuglink switch to create
206
  a two part program distribution - one a stripped executable and the other the
207
  debugging info.
208
 
209
* objcopy now accepts --add-gnu-debuglink= to insert a .gnu_debuglink
210
  section into a (presumably stripped) executable.  This allows the debug
211
  information for the file to be held in a separate file.
212
 
213
* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
214
  single-character representation.  This can be checked by running nm
215
  with the -a switch.
216
 
217
Changes in 2.14:
218
 
219
* Added --info switch to objcopy and strip.
220
 
221
* Support for Vitesse IQ2000 added by Red Hat.
222
 
223
* Added 'S' encoding to strings to allow the display of 8-bit characters.
224
 
225
* Added --prefix-symbols=, --prefix-sections= and
226
  --prefix-alloc-sections= to objcopy.
227
 
228
* readelf can handle the extensions to the DWARF2 spec used by the Unified
229
  Parallel C compiler.
230
 
231
* BFD no longer declares a "boolean" type, to avoid clashes with other
232
  headers that declare the same.  Users of BFD should replace boolean,
233
  false and true, with int, 0 and 1, or define their own boolean type.
234
 
235
* Support for IP2K added by Denis Chertykov.
236
 
237
Changes in 2.13:
238
 
239
* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
240
  and FR500 included.
241
 
242
Changes in version 2.12:
243
 
244
* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
245
 
246
* size: Add --totals to display summary of sizes (Berkeley format only).
247
 
248
* readelf: Add --wide option to not break section header or segment listing
249
  lines to fit into 80 columns.
250
 
251
* strings: Add --encoding to display wide character strings.  By Markus Kuhn.
252
 
253
* objcopy: Add --rename-section to change section names.
254
 
255
* readelf: Support added for DWARF 2.1 extensions.  Support added for
256
  displaying the contents of .debug.macinfo sections.
257
 
258
* New command line switches added to objcopy to allow symbols to be kept as
259
  global symbols, and also to specify files containing lists of such symbols.
260
  by Honda Hiroki.
261
 
262
* Support for OpenRISC by Johan Rydberg.
263
 
264
* New command line switch to objcopy --alt-machine-code which creates a binary
265
  with an alternate machine code if one is defined in the architecture
266
  description.  Only supported for ELF targets.  By Alexandre Oliva.
267
 
268
* New command line switch to objcopy -B (or --binary-architecture) which sets
269
  the architecture of the output file to the given argument.  This option only
270
  makes sense, if the input target is binary.  Otherwise it is ignored.
271
  By Stefan Geuken.
272
 
273
* Support for PDP-11 by Lars Brinkhoff.
274
 
275
Changes in binutils 2.11:
276
 
277
* Add support for ARM v5t and v5te architectures and Intel's XScale ARM
278
  extenstions.
279
 
280
* Add --srec-len and --srec-forceS3 command line switch to objcopy.
281
  By Luciano Gemme.
282
 
283
* Support for the MIPS32, by Anders Norlander.
284
 
285
* Support for the i860, by Jason Eckhardt.
286
 
287
* Support for CRIS (Axis Communications ETRAX series).
288
 
289
Changes in binutils 2.10:
290
 
291
* Support for 64-bit ELF on HPPA.
292
 
293
* New command line switch to objdump --file-start-context which shows the
294
  entire file contents up to the source line first encountered for a given
295
  file.
296
 
297
* New command line switch to objdump -M (or --disassembler-options) which takes
298
  a parameter which can then be interpreted on a per-target basis by the
299
  disassembler.  Used by ARM targets to select register name sets, ISA, APCS or
300
  raw verions.
301
 
302
* objdump support for -mi386:intel which causes disassembly to be displayed
303
  with intel syntax.
304
 
305
* New program: readelf.  This displays the contents of ELF format files,
306
  regardless of target machine.
307
 
308
* objcopy now takes --change-section-lma, --change-section-vma, and
309
  --change-section-address options.  The old --adjust-section-vma option is
310
  equivalent to --change-section-address.  The other --adjust-* options are now
311
  renamed to --change-*, although --adjust-* continues to work.
312
 
313
* objcopy has a --redefine-sym option that lets you rename symbols.
314
 
315
* objcopy now takes a -j/--only-section option to copy only the specified
316
  sections.
317
 
318
* dlltool now supports the IMPORTS command.
319
 
320
* dlltool now takes --export-all-symbols, --no-export-all-symbols,
321
  --exclude-symbols, and --no-default-excludes options.
322
 
323
Changes in binutils 2.9:
324
 
325
* Added windres program, which can be used to manipulate resources in WIN32
326
  files as used on Windows 95 and Windows NT.
327
 
328
* The objcopy --gap-fill and --pad-to options operate on the LMA rather than
329
  the VMA of the sections.
330
 
331
* Added S modifier to ar to not build a symbol table.
332
 
333
Changes in binutils 2.8:
334
 
335
* The objdump disassembly format has been changed, and hopefully improved.  Use
336
  the new --prefix-addresses option to get the old format.  There are also new
337
  --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
338
  output.
339
 
340
* Formats may now be specified as configuration triplets.  For example,
341
  objdump -b i386-pc-linux.  The triplets are not passed through config.sub,
342
  so they must be in canonical form.
343
 
344
* Added new addr2line program.  This uses the debugging information to convert
345
  an address into a file name and line number within a program.
346
 
347
* Added --change-leading-char argument to objcopy.
348
 
349
* Added --weaken argument to objcopy.
350
 
351
* objdump --dynamic-reloc now works on ELF executables and shared libraries.
352
 
353
* Added --adjust-vma option to objdump.
354
 
355
* Added -C/--demangle option to objdump.
356
 
357
* Added -p/--preserve-dates option to strip and objcopy.
358
 
359
Changes in binutils 2.7:
360
 
361
* Added --enable-shared and --enable-commonbfdlib options to configure.
362
 
363
* Added --debugging argument to objdump and objcopy.
364
 
365
* Added --defined-only argument to nm.
366
 
367
* Added --remove-leading-char argument to objcopy.
368
 
369
* The objdump --line-numbers option is now meaningful with --reloc.
370
 
371
* Added --line-numbers option to nm.
372
 
373
* Added --endian/-EB/-EL option to objdump.
374
 
375
* Added support for Alpha OpenVMS/AXP.
376
 
377
Changes in binutils 2.6:
378
 
379
* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
380
 
381
* Added several arguments to objcopy to provide some control over how the new
382
  file is laid out in memory.  Also added binary output format to BFD to permit
383
  generating plain binary files.
384
 
385
* Added --start-address and --stop-address options to objdump.
386
 
387
* ar and ranlib now work on AIX.  The tools are now built by default on AIX.
388
 
389
Changes in binutils 2.5:
390
 
391
* Changed objdump -dr to dump the relocs interspersed with the assembly
392
  listing, for a more useful listing of relocatable files.
393
 
394
* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
395
  Added -D/--disassemble-all option to disassemble all sections.
396
 
397
* Added --size-sort option to nm.
398
 
399
* strip and objcopy should now be able to handle dynamically linked ELF
400
  executables.
401
 
402
Changes in binutils 2.4:
403
 
404
* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
405
  PowerPC (except ar and ranlib; by Ian Taylor).
406
 
407
* Support for Irix 5.
408
 
409
* Programs `strip' and `objcopy' will not attempt to write dynamically linked
410
  ELF output files, since BFD currently can't create them properly.
411
 
412
Changes in binutils 2.3:
413
 
414
* A new --stabs argument has been added to objdump to dump stabs sections in
415
  ELF and COFF files.
416
 
417
* A new program, nlmconv, has been added.  It can convert object files into
418
  Novell NetWare Loadable Modules.
419
 
420
* The strings program has been added.
421
 
422
Changes in binutils 2.2:
423
 
424
* The 'copy' program has been renamed to 'objcopy', for consistency with
425
  'objdump', and because 'copy' might more plausibly be used as a synonym for
426
  'cp'.
427
 
428
* The new stand-alone program c++filt is a filter that converts encoded
429
  (mangled) C++ assembly-level identifiers to user-level names.  (Note: This
430
  may get moved to the gcc distribution.)
431
 
432
* nm -o on an archive now prefixes each line with the archive name, matching
433
  the output from BSD nm.
434
 
435
* ar (and ld) can now read (but not write) BSD4.4-style archives.
436
 
437
* New support for H8500, Z8000, and the Hitach SH.
438
 
439
* Dis-assembler interface changed to allow sharing with gdb.
440
 
441
* There is new Elf code, but it is not yet ready for general use.
442
 
443
* There is the beginnings of a test suite.
444
 
445
Changes in binutils 2.1:
446
 
447
* There is now support for writing ECOFF files, so ld and the other utilities
448
  should work on Risc/Ultrix and Irix.  Please let us know how well this works.
449
 
450
* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
451
  version), if there are any object files in the archive.  So running ranlib is
452
  now redundant (unless the non-standard q command is used).  This is required
453
  for Posix.2 conformance.
454
 
455
* The archive-reading code now reads both BSD-style and SYSV-style archives
456
  independently of the selected target format.  This is to encourage people to
457
  switch to SYSV-format, which has a number of advantages.
458
 
459
* The strip and copy programs now have options to remove debug-symbols only
460
  and/or local symbols only.  They now also support long options.
