3 | Changes in binutils 2.10: | |
4 | ||
c2c40d93 ILT |
5 | * objdump support for -mi386:intel which causes disassembly to be displayed |
6 | with intel syntax. | |
252b5132 RH |
7 | |
8 | * New program: readelf. This displays the contents of ELF format files, | |
9 | regardless of target machine. | |
10 | ||
11 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
12 | --change-section-address options. The old --adjust-section-vma option is | |
13 | equivalent to --change-section-address. The other --adjust-* options are now | |
14 | renamed to --change-*, although --adjust-* continues to work. | |
15 | ||
16 | * dlltool now supports the IMPORTS command. | |
17 | ||
18 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, | |
19 | --exclude-symbols, and --no-default-excludes options. | |
20 | ||
f91ea849 ILT |
21 | * objcopy now takes a -j/--only-section option to copy only the specified |
22 | sections. | |
23 | ||
252b5132 RH |
24 | Changes in binutils 2.9: |
25 | ||
26 | * Added windres program, which can be used to manipulate resources in WIN32 | |
27 | files as used on Windows 95 and Windows NT. | |
28 | ||
29 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
30 | the VMA of the sections. | |
31 | ||
32 | * Added S modifier to ar to not build a symbol table. | |
33 | ||
34 | Changes in binutils 2.8: | |
35 | ||
36 | * The objdump disassembly format has been changed, and hopefully improved. Use | |
37 | the new --prefix-addresses option to get the old format. There are also new | |
38 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
39 | output. | |
40 | ||
41 | * Formats may now be specified as configuration triplets. For example, | |
42 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
43 | so they must be in canonical form. | |
44 | ||
45 | * Added new addr2line program. This uses the debugging information to convert | |
46 | an address into a file name and line number within a program. | |
47 | ||
48 | * Added --change-leading-char argument to objcopy. | |
49 | ||
50 | * Added --weaken argument to objcopy. | |
51 | ||
52 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. | |
53 | ||
54 | * Added --adjust-vma option to objdump. | |
55 | ||
56 | * Added -C/--demangle option to objdump. | |
57 | ||
58 | * Added -p/--preserve-dates option to strip and objcopy. | |
59 | ||
60 | Changes in binutils 2.7: | |
61 | ||
62 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
63 | ||
64 | * Added --debugging argument to objdump and objcopy. | |
65 | ||
66 | * Added --defined-only argument to nm. | |
67 | ||
68 | * Added --remove-leading-char argument to objcopy. | |
69 | ||
70 | * The objdump --line-numbers option is now meaningful with --reloc. | |
71 | ||
72 | * Added --line-numbers option to nm. | |
73 | ||
74 | * Added --endian/-EB/-EL option to objdump. | |
75 | ||
76 | * Added support for Alpha OpenVMS/AXP. | |
77 | ||
78 | Changes in binutils 2.6: | |
79 | ||
80 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
81 | ||
82 | * Added several arguments to objcopy to provide some control over how the new | |
83 | file is laid out in memory. Also added binary output format to BFD to permit | |
84 | generating plain binary files. | |
85 | ||
86 | * Added --start-address and --stop-address options to objdump. | |
87 | ||
88 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
89 | ||
90 | Changes in binutils 2.5: | |
91 | ||
92 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
93 | listing, for a more useful listing of relocateable files. | |
94 | ||
95 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
96 | Added -D/--disassemble-all option to disassemble all sections. | |
97 | ||
98 | * Added --size-sort option to nm. | |
99 | ||
100 | * strip and objcopy should now be able to handle dynamically linked ELF | |
101 | executables. | |
102 | ||
103 | Changes in binutils 2.4: | |
104 | ||
105 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
106 | PowerPC (except ar and ranlib; by Ian Taylor). | |
107 | ||
108 | * Support for Irix 5. | |
109 | ||
110 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
111 | ELF output files, since BFD currently can't create them properly. | |
112 | ||
113 | Changes in binutils 2.3: | |
114 | ||
115 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
116 | ELF and COFF files. | |
117 | ||
118 | * A new program, nlmconv, has been added. It can convert object files into | |
119 | Novell NetWare Loadable Modules. | |
120 | ||
121 | * The strings program has been added. | |
122 | ||
123 | Changes in binutils 2.2: | |
124 | ||
125 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
126 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
127 | 'cp'. | |
128 | ||
129 | * The new stand-alone program c++filt is a filter that converts encoded | |
130 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
131 | may get moved to the gcc distribution.) | |
132 | ||
133 | * nm -o on an archive now prefixes each line with the archive name, matching | |
134 | the output from BSD nm. | |
135 | ||
136 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
137 | ||
138 | * New support for H8500, Z8000, and the Hitach SH. | |
139 | ||
140 | * Dis-assembler interface changed to allow sharing with gdb. | |
141 | ||
142 | * There is new Elf code, but it is not yet ready for general use. | |
143 | ||
144 | * There is the beginnings of a test suite. | |
145 | ||
146 | Changes in binutils 2.1: | |
147 | ||
148 | * There is now support for writing ECOFF files, so ld and the other utilities | |
149 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
150 | ||
151 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
152 | version), if there are any object files in the archive. So running ranlib is | |
153 | now redundant (unless the non-standard q command is used). This is required | |
154 | for Posix.2 conformance. | |
155 | ||
156 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
157 | independently of the selected target format. This is to encourage people to | |
158 | switch to SYSV-format, which has a number of advantages. | |
159 | ||
160 | * The strip and copy programs now have options to remove debug-symbols only | |
161 | and/or local symbols only. They now also support long options. | |
