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