3 | Changes in binutils 2.10: | |
4 | ||
f1563258 TW |
5 | * New command line switch to objdump --file-start-context which shows the |
6 | entire file contents up to the source line first encountered for a given | |
7 | file. | |
8 | ||
dd92f639 NC |
9 | * New command line switch to objdump -M (or --disassembler-options) which takes |
10 | a parameter which can then be interpreted on a per-target basis by the | |
11 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or | |
12 | raw verions. | |
13 | ||
c2c40d93 ILT |
14 | * objdump support for -mi386:intel which causes disassembly to be displayed |
15 | with intel syntax. | |
252b5132 RH |
16 | |
17 | * New program: readelf. This displays the contents of ELF format files, | |
18 | regardless of target machine. | |
19 | ||
20 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
21 | --change-section-address options. The old --adjust-section-vma option is | |
22 | equivalent to --change-section-address. The other --adjust-* options are now | |
23 | renamed to --change-*, although --adjust-* continues to work. | |
24 | ||
57938635 AM |
25 | * objcopy has a --redefine-sym option that lets you rename symbols. |
26 | ||
27 | * objcopy now takes a -j/--only-section option to copy only the specified | |
28 | sections. | |
29 | ||
252b5132 RH |
30 | * dlltool now supports the IMPORTS command. |
31 | ||
32 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
33 | --exclude-symbols, and --no-default-excludes options. | |
34 | ||
35 | Changes in binutils 2.9: | |
36 | ||
37 | * Added windres program, which can be used to manipulate resources in WIN32 | |
38 | files as used on Windows 95 and Windows NT. | |
39 | ||
40 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
41 | the VMA of the sections. | |
42 | ||
43 | * Added S modifier to ar to not build a symbol table. | |
44 | ||
45 | Changes in binutils 2.8: | |
46 | ||
47 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
48 | the new --prefix-addresses option to get the old format. There are also new | |
49 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
50 | output. | |
51 | ||
52 | * Formats may now be specified as configuration triplets. For example, | |
53 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
54 | so they must be in canonical form. | |
55 | ||
56 | * Added new addr2line program. This uses the debugging information to convert | |
57 | an address into a file name and line number within a program. | |
58 | ||
59 | * Added --change-leading-char argument to objcopy. | |
60 | ||
61 | * Added --weaken argument to objcopy. | |
62 | ||
63 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
64 | ||
65 | * Added --adjust-vma option to objdump. | |
66 | ||
67 | * Added -C/--demangle option to objdump. | |
68 | ||
69 | * Added -p/--preserve-dates option to strip and objcopy. | |
70 | ||
71 | Changes in binutils 2.7: | |
72 | ||
73 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
74 | ||
75 | * Added --debugging argument to objdump and objcopy. | |
76 | ||
77 | * Added --defined-only argument to nm. | |
78 | ||
79 | * Added --remove-leading-char argument to objcopy. | |
80 | ||
81 | * The objdump --line-numbers option is now meaningful with --reloc. | |
82 | ||
83 | * Added --line-numbers option to nm. | |
84 | ||
85 | * Added --endian/-EB/-EL option to objdump. | |
86 | ||
87 | * Added support for Alpha OpenVMS/AXP. | |
88 | ||
89 | Changes in binutils 2.6: | |
90 | ||
91 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
92 | ||
93 | * Added several arguments to objcopy to provide some control over how the new | |
94 | file is laid out in memory. Also added binary output format to BFD to permit | |
95 | generating plain binary files. | |
96 | ||
97 | * Added --start-address and --stop-address options to objdump. | |
98 | ||
99 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
100 | ||
101 | Changes in binutils 2.5: | |
102 | ||
103 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
104 | listing, for a more useful listing of relocateable files. | |
105 | ||
106 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
107 | Added -D/--disassemble-all option to disassemble all sections. | |
108 | ||
109 | * Added --size-sort option to nm. | |
110 | ||
111 | * strip and objcopy should now be able to handle dynamically linked ELF | |
112 | executables. | |
113 | ||
114 | Changes in binutils 2.4: | |
115 | ||
116 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
117 | PowerPC (except ar and ranlib; by Ian Taylor). | |
118 | ||
119 | * Support for Irix 5. | |
120 | ||
121 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
122 | ELF output files, since BFD currently can't create them properly. | |
123 | ||
124 | Changes in binutils 2.3: | |
125 | ||
126 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
127 | ELF and COFF files. | |
128 | ||
129 | * A new program, nlmconv, has been added. It can convert object files into | |
130 | Novell NetWare Loadable Modules. | |
131 | ||
132 | * The strings program has been added. | |
133 | ||
134 | Changes in binutils 2.2: | |
135 | ||
136 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
137 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
138 | 'cp'. | |
139 | ||
140 | * The new stand-alone program c++filt is a filter that converts encoded | |
141 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
142 | may get moved to the gcc distribution.) | |
143 | ||
144 | * nm -o on an archive now prefixes each line with the archive name, matching | |
145 | the output from BSD nm. | |
146 | ||
147 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
148 | ||
149 | * New support for H8500, Z8000, and the Hitach SH. | |
150 | ||
151 | * Dis-assembler interface changed to allow sharing with gdb. | |
152 | ||
153 | * There is new Elf code, but it is not yet ready for general use. | |
154 | ||
155 | * There is the beginnings of a test suite. | |
156 | ||
157 | Changes in binutils 2.1: | |
158 | ||
159 | * There is now support for writing ECOFF files, so ld and the other utilities | |
160 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
161 | ||
162 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
163 | version), if there are any object files in the archive. So running ranlib is | |
164 | now redundant (unless the non-standard q command is used). This is required | |
165 | for Posix.2 conformance. | |
166 | ||
167 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
168 | independently of the selected target format. This is to encourage people to | |
169 | switch to SYSV-format, which has a number of advantages. | |
170 | ||
171 | * The strip and copy programs now have options to remove debug-symbols only | |
172 | and/or local symbols only. They now also support long options. | |
