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