3 | Changes since binutils 2.7 |
4 | ||
5 | * Formats may now be specified as configuration triplets. For example, | |
6 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, | |
7 | so they must be in canonical form. | |
8 | ||
9 | * Added --change-leading-char argument to objcopy. | |
10 | ||

11 | Changes since binutils 2.6 |
12 | ||
13 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
14 | ||
15 | * Added --debugging argument to objdump and objcopy. | |
16 | ||
17 | * Added --defined-only argument to nm. | |
18 | ||
19 | * Added --remove-leading-char argument to objcopy. | |
20 | ||
21 | * The objdump --line-numbers option is now meaningful with --reloc. | |
22 | ||
55311d1c ILT |
23 | * Added --line-numbers option to nm. |
24 | ||
25 | * Added --endian/-EB/-EL option to objdump. | |
26 | ||
27 | * Added support for Alpha OpenVMS/AXP. | |
28 | ||

29 | Changes since binutils 2.5 |
30 | ||
31 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
32 | ||
33 | * Added several arguments to objcopy to provide some control over how the new | |
34 | file is laid out in memory. Also added binary output format to BFD to permit | |
35 | generating plain binary files. | |
36 | ||
37 | * Added --start-address and --stop-address options to objdump. | |
38 | ||
39 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
40 | ||
41 | Changes since binutils 2.4 | |
42 | ||
43 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
44 | listing, for a more useful listing of relocateable files. | |
45 | ||
46 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
47 | Added -D/--disassemble-all option to disassemble all sections. | |
48 | ||
49 | * Added --size-sort option to nm. | |
50 | ||
51 | * strip and objcopy should now be able to handle dynamically linked ELF | |
52 | executables. | |
53 | ||
54 | Changes since binutils 2.3 | |
55 | ||
56 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
57 | PowerPC (except ar and ranlib; by Ian Taylor). | |
58 | ||
59 | * Support for Irix 5. | |
60 | ||
61 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
62 | ELF output files, since BFD currently can't create them properly. | |
63 | ||
64 | Changes since binutils 2.2 | |
65 | ||
66 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
67 | ELF and COFF files. | |
68 | ||
69 | * A new program, nlmconv, has been added. It can convert object files into | |
70 | Novell NetWare Loadable Modules. | |
71 | ||
72 | * The strings program has been added. | |
73 | ||
74 | Changes since binutils 2.1 | |
75 | ||
76 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
77 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
78 | 'cp'. | |
79 | ||
80 | * The new stand-alone program c++filt is a filter that converts encoded | |
81 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
82 | may get moved to the gcc distribution.) | |
83 | ||
84 | * nm -o on an archive now prefixes each line with the archive name, matching | |
85 | the output from BSD nm. | |
86 | ||
87 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
88 | ||
89 | * New support for H8500, Z8000, and the Hitach SH. | |
90 | ||
91 | * Dis-assembler interface changed to allow sharing with gdb. | |
92 | ||
93 | * There is new Elf code, but it is not yet ready for general use. | |
94 | ||
95 | * There is the beginnings of a test suite. | |
96 | ||
97 | Changes since binutils 2.0 | |
98 | ||
99 | * There is now support for writing ECOFF files, so ld and the other utilities | |
100 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
101 | ||
102 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
103 | version), if there are any object files in the archive. So running ranlib is | |
104 | now redundant (unless the non-standard q command is used). This is required | |
105 | for Posix.2 conformance. | |
106 | ||
107 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
108 | independently of the selected target format. This is to encourage people to | |
109 | switch to SYSV-format, which has a number of advantages. | |
110 | ||
111 | * The strip and copy programs now have options to remove debug-symbols only | |
112 | and/or local symbols only. They now also support long options. | |
