[deliverable/binutils-gdb.git] / binutils / NEWS
1 -*- text -*-
2
3 * Support for Vitesse IQ2000 added by Red Hat.
4
5 * Added 'S' encoding to strings to allow the display of 8-bit characters.
6
7 * Added --prefix-symbols=<text>, --prefix-sections=<text> and
8 --prefix-alloc-sections=<text> to objcopy.
9
10 * readelf can handle the extensions to the DWARF2 spec used by the Unified
11 Parallel C compiler.
12
13 * BFD no longer declares a "boolean" type, to avoid clashes with other
14 headers that declare the same. Users of BFD should replace boolean,
15 false and true, with int, 0 and 1, or define their own boolean type.
16
17 * Support for IP2K added by Denis Chertykov.
18
19 Changes in 2.13:
20
21 * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
22 and FR500 included.
23
24 Changes in version 2.12:
25
26 * Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
27
28 * size: Add --totals to display summary of sizes (Berkeley format only).
29
30 * readelf: Add --wide option to not break section header or segment listing
31 lines to fit into 80 columns.
32
33 * strings: Add --encoding to display wide character strings. By Markus Kuhn.
34
35 * objcopy: Add --rename-section to change section names.
36
37 * readelf: Support added for DWARF 2.1 extensions. Support added for
38 displaying the contents of .debug.macinfo sections.
39
40 * New command line switches added to objcopy to allow symbols to be kept as
41 global symbols, and also to specify files containing lists of such symbols.
42 by Honda Hiroki.
43
44 * Support for OpenRISC by Johan Rydberg.
45
46 * New command line switch to objcopy --alt-machine-code which creates a binary
47 with an alternate machine code if one is defined in the architecture
48 description. Only supported for ELF targets. By Alexandre Oliva.
49
50 * New command line switch to objcopy -B (or --binary-architecture) which sets
51 the architecture of the output file to the given argument. This option only
52 makes sense, if the input target is binary. Otherwise it is ignored.
53 By Stefan Geuken.
54
55 * Support for PDP-11 by Lars Brinkhoff.
56
57 Changes in binutils 2.11:
58
59 * Add support for ARM v5t and v5te architectures and Intel's XScale ARM
60 extenstions.
61
62 * Add --srec-len and --srec-forceS3 command line switch to objcopy.
63 By Luciano Gemme.
64
65 * Support for the MIPS32, by Anders Norlander.
66
67 * Support for the i860, by Jason Eckhardt.
68
69 * Support for CRIS (Axis Communications ETRAX series).
70
71 Changes in binutils 2.10:
72
73 * Support for 64-bit ELF on HPPA.
74
75 * New command line switch to objdump --file-start-context which shows the
76 entire file contents up to the source line first encountered for a given
77 file.
78
79 * New command line switch to objdump -M (or --disassembler-options) which takes
80 a parameter which can then be interpreted on a per-target basis by the
81 disassembler. Used by ARM targets to select register name sets, ISA, APCS or
82 raw verions.
83
84 * objdump support for -mi386:intel which causes disassembly to be displayed
85 with intel syntax.
86
87 * New program: readelf. This displays the contents of ELF format files,
88 regardless of target machine.
89
90 * objcopy now takes --change-section-lma, --change-section-vma, and
91 --change-section-address options. The old --adjust-section-vma option is
92 equivalent to --change-section-address. The other --adjust-* options are now
93 renamed to --change-*, although --adjust-* continues to work.
94
95 * objcopy has a --redefine-sym option that lets you rename symbols.
96
97 * objcopy now takes a -j/--only-section option to copy only the specified
98 sections.
99
100 * dlltool now supports the IMPORTS command.
101
102 * dlltool now takes --export-all-symbols, --no-export-all-symbols,
103 --exclude-symbols, and --no-default-excludes options.
104
105 Changes in binutils 2.9:
106
107 * Added windres program, which can be used to manipulate resources in WIN32
108 files as used on Windows 95 and Windows NT.
109
110 * The objcopy --gap-fill and --pad-to options operate on the LMA rather than
111 the VMA of the sections.
112
113 * Added S modifier to ar to not build a symbol table.
114
115 Changes in binutils 2.8:
116
117 * The objdump disassembly format has been changed, and hopefully improved. Use
118 the new --prefix-addresses option to get the old format. There are also new
119 --disassemble-zeroes and --no-show-raw-insn options which affect disassembler
120 output.
121
122 * Formats may now be specified as configuration triplets. For example,
123 objdump -b i386-pc-linux. The triplets are not passed through config.sub,
124 so they must be in canonical form.
125
126 * Added new addr2line program. This uses the debugging information to convert
127 an address into a file name and line number within a program.
128
129 * Added --change-leading-char argument to objcopy.
130
131 * Added --weaken argument to objcopy.
132
133 * objdump --dynamic-reloc now works on ELF executables and shared libraries.
134
135 * Added --adjust-vma option to objdump.
136
137 * Added -C/--demangle option to objdump.
138
139 * Added -p/--preserve-dates option to strip and objcopy.
140
141 Changes in binutils 2.7:
142
143 * Added --enable-shared and --enable-commonbfdlib options to configure.
144
145 * Added --debugging argument to objdump and objcopy.
146
147 * Added --defined-only argument to nm.
148
149 * Added --remove-leading-char argument to objcopy.
150
151 * The objdump --line-numbers option is now meaningful with --reloc.
152
153 * Added --line-numbers option to nm.
154
155 * Added --endian/-EB/-EL option to objdump.
156
157 * Added support for Alpha OpenVMS/AXP.
158
159 Changes in binutils 2.6:
160
161 * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
162
163 * Added several arguments to objcopy to provide some control over how the new
164 file is laid out in memory. Also added binary output format to BFD to permit
165 generating plain binary files.
166
167 * Added --start-address and --stop-address options to objdump.
168
169 * ar and ranlib now work on AIX. The tools are now built by default on AIX.
170
171 Changes in binutils 2.5:
172
173 * Changed objdump -dr to dump the relocs interspersed with the assembly
174 listing, for a more useful listing of relocateable files.
175
176 * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
177 Added -D/--disassemble-all option to disassemble all sections.
178
179 * Added --size-sort option to nm.
180
181 * strip and objcopy should now be able to handle dynamically linked ELF
182 executables.
183
184 Changes in binutils 2.4:
185
186 * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
187 PowerPC (except ar and ranlib; by Ian Taylor).
188
189 * Support for Irix 5.
190
191 * Programs `strip' and `objcopy' will not attempt to write dynamically linked
192 ELF output files, since BFD currently can't create them properly.
193
194 Changes in binutils 2.3:
195
196 * A new --stabs argument has been added to objdump to dump stabs sections in
197 ELF and COFF files.
198
199 * A new program, nlmconv, has been added. It can convert object files into
200 Novell NetWare Loadable Modules.
201
202 * The strings program has been added.
203
204 Changes in binutils 2.2:
205
206 * The 'copy' program has been renamed to 'objcopy', for consistency with
207 'objdump', and because 'copy' might more plausibly be used as a synonym for
208 'cp'.
209
210 * The new stand-alone program c++filt is a filter that converts encoded
211 (mangled) C++ assembly-level identifiers to user-level names. (Note: This
212 may get moved to the gcc distribution.)
213
214 * nm -o on an archive now prefixes each line with the archive name, matching
215 the output from BSD nm.
216
217 * ar (and ld) can now read (but not write) BSD4.4-style archives.
218
219 * New support for H8500, Z8000, and the Hitach SH.
220
221 * Dis-assembler interface changed to allow sharing with gdb.
222
223 * There is new Elf code, but it is not yet ready for general use.
224
225 * There is the beginnings of a test suite.
226
227 Changes in binutils 2.1:
228
229 * There is now support for writing ECOFF files, so ld and the other utilities
230 should work on Risc/Ultrix and Irix. Please let us know how well this works.
231
232 * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
233 version), if there are any object files in the archive. So running ranlib is
234 now redundant (unless the non-standard q command is used). This is required
235 for Posix.2 conformance.
236
237 * The archive-reading code now reads both BSD-style and SYSV-style archives
238 independently of the selected target format. This is to encourage people to
239 switch to SYSV-format, which has a number of advantages.
240
241 * The strip and copy programs now have options to remove debug-symbols only
242 and/or local symbols only. They now also support long options.
