3 | Changes in binutils 2.10: |
4 | ||
5 | * objcopy now takes --change-section-lma, --change-section-vma, and | |
6 | --change-section-address options. The old --adjust-section-vma option is | |
7 | equivalent to --change-section-address. The other --adjust-* options are now | |
8 | renamed to --change-*, although --adjust-* continues to work. | |
9 | ||
10 | * dlltool now supports the IMPORTS command. | |
11 | ||
12 | Changes in binutils 2.9: | |
13 | ||
14 | * Added windres program, which can be used to manipulate resources in WIN32 | |
15 | files as used on Windows 95 and Windows NT. | |
16 | ||
17 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than | |
18 | the VMA of the sections. | |
19 | ||
20 | * Added S modifier to ar to not build a symbol table. | |
21 | ||
5c59269f | 22 | Changes in binutils 2.8: |
55311d1c | 23 | |
9681fa45 | 24 | * The objdump disassembly format has been changed, and hopefully improved. Use |
5c59269f ILT |
25 | the new --prefix-addresses option to get the old format. There are also new |
26 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler | |
27 | output. | |
9681fa45 | 28 | |
55311d1c ILT |
29 | * Formats may now be specified as configuration triplets. For example, |
30 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
31 | so they must be in canonical form. | |
32 | ||
8d9b566d ILT |
33 | * Added new addr2line program. This uses the debugging information to convert |
34 | an address into a file name and line number within a program. | |
35 | ||
55311d1c ILT |
36 | * Added --change-leading-char argument to objcopy. |
37 | ||
9a442fe8 ILT |
38 | * Added --weaken argument to objcopy. |
39 | ||
9681fa45 ILT |
40 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. |
41 | ||
5c59269f ILT |
42 | * Added --adjust-vma option to objdump. |
43 | ||
8d9b566d ILT |
44 | * Added -C/--demangle option to objdump. |
45 | ||
bba89785 ILT |
46 | * Added -p/--preserve-dates option to strip and objcopy. |
47 | ||
5c59269f | 48 | Changes in binutils 2.7: |
11548211 ILT |
49 | |
50 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
51 | ||
52 | * Added --debugging argument to objdump and objcopy. | |
53 | ||
54 | * Added --defined-only argument to nm. | |
55 | ||
56 | * Added --remove-leading-char argument to objcopy. | |
57 | ||
58 | * The objdump --line-numbers option is now meaningful with --reloc. | |
59 | ||
55311d1c ILT |
60 | * Added --line-numbers option to nm. |
61 | ||
62 | * Added --endian/-EB/-EL option to objdump. | |
63 | ||
64 | * Added support for Alpha OpenVMS/AXP. | |
65 | ||
5c59269f | 66 | Changes in binutils 2.6: |
11548211 ILT |
67 | |
68 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
69 | ||
70 | * Added several arguments to objcopy to provide some control over how the new | |
71 | file is laid out in memory. Also added binary output format to BFD to permit | |
72 | generating plain binary files. | |
73 | ||
74 | * Added --start-address and --stop-address options to objdump. | |
75 | ||
76 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
77 | ||
5c59269f | 78 | Changes in binutils 2.5: |
11548211 ILT |
79 | |
80 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
81 | listing, for a more useful listing of relocateable files. | |
82 | ||
83 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
84 | Added -D/--disassemble-all option to disassemble all sections. | |
85 | ||
86 | * Added --size-sort option to nm. | |
87 | ||
88 | * strip and objcopy should now be able to handle dynamically linked ELF | |
89 | executables. | |
90 | ||
5c59269f | 91 | Changes in binutils 2.4: |
11548211 ILT |
92 | |
93 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
94 | PowerPC (except ar and ranlib; by Ian Taylor). | |
95 | ||
96 | * Support for Irix 5. | |
97 | ||
98 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
99 | ELF output files, since BFD currently can't create them properly. | |
100 | ||
5c59269f | 101 | Changes in binutils 2.3: |
11548211 ILT |
102 | |
103 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
104 | ELF and COFF files. | |
105 | ||
106 | * A new program, nlmconv, has been added. It can convert object files into | |
107 | Novell NetWare Loadable Modules. | |
108 | ||
109 | * The strings program has been added. | |
110 | ||
5c59269f | 111 | Changes in binutils 2.2: |
11548211 ILT |
112 | |
113 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
114 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
115 | 'cp'. | |
116 | ||
117 | * The new stand-alone program c++filt is a filter that converts encoded | |
118 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
119 | may get moved to the gcc distribution.) | |
120 | ||
121 | * nm -o on an archive now prefixes each line with the archive name, matching | |
122 | the output from BSD nm. | |
123 | ||
124 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
125 | ||
126 | * New support for H8500, Z8000, and the Hitach SH. | |
127 | ||
128 | * Dis-assembler interface changed to allow sharing with gdb. | |
129 | ||
130 | * There is new Elf code, but it is not yet ready for general use. | |
131 | ||
132 | * There is the beginnings of a test suite. | |
133 | ||
5c59269f | 134 | Changes in binutils 2.1: |
11548211 ILT |
135 | |
136 | * There is now support for writing ECOFF files, so ld and the other utilities | |
137 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
138 | ||
139 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
140 | version), if there are any object files in the archive. So running ranlib is | |
141 | now redundant (unless the non-standard q command is used). This is required | |
142 | for Posix.2 conformance. | |
143 | ||
144 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
145 | independently of the selected target format. This is to encourage people to | |
146 | switch to SYSV-format, which has a number of advantages. | |
147 | ||
148 | * The strip and copy programs now have options to remove debug-symbols only | |
149 | and/or local symbols only. They now also support long options. | |
