| 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 | ||
| 14 | * Added --change-leading-char argument to objcopy. | |
| 15 | ||
| 9a442fe8 ILT |
16 | * Added --weaken argument to objcopy. |
| 17 | ||
| 9681fa45 ILT |
18 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. |
| 19 | ||
| 5c59269f ILT |
20 | * Added --adjust-vma option to objdump. |
| 21 | ||
| 22 | Changes in binutils 2.7: | |
| 11548211 ILT |
23 | |
| 24 | * Added --enable-shared and --enable-commonbfdlib options to configure. | |
| 25 | ||
| 26 | * Added --debugging argument to objdump and objcopy. | |
| 27 | ||
| 28 | * Added --defined-only argument to nm. | |
| 29 | ||
| 30 | * Added --remove-leading-char argument to objcopy. | |
| 31 | ||
| 32 | * The objdump --line-numbers option is now meaningful with --reloc. | |
| 33 | ||
| 55311d1c ILT |
34 | * Added --line-numbers option to nm. |
| 35 | ||
| 36 | * Added --endian/-EB/-EL option to objdump. | |
| 37 | ||
| 38 | * Added support for Alpha OpenVMS/AXP. | |
| 39 | ||
| 5c59269f | 40 | Changes in binutils 2.6: |
| 11548211 ILT |
41 | |
| 42 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. | |
| 43 | ||
| 44 | * Added several arguments to objcopy to provide some control over how the new | |
| 45 | file is laid out in memory. Also added binary output format to BFD to permit | |
| 46 | generating plain binary files. | |
| 47 | ||
| 48 | * Added --start-address and --stop-address options to objdump. | |
| 49 | ||
| 50 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. | |
| 51 | ||
| 5c59269f | 52 | Changes in binutils 2.5: |
| 11548211 ILT |
53 | |
| 54 | * Changed objdump -dr to dump the relocs interspersed with the assembly | |
| 55 | listing, for a more useful listing of relocateable files. | |
| 56 | ||
| 57 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. | |
| 58 | Added -D/--disassemble-all option to disassemble all sections. | |
| 59 | ||
| 60 | * Added --size-sort option to nm. | |
| 61 | ||
| 62 | * strip and objcopy should now be able to handle dynamically linked ELF | |
| 63 | executables. | |
| 64 | ||
| 5c59269f | 65 | Changes in binutils 2.4: |
| 11548211 ILT |
66 | |
| 67 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and | |
| 68 | PowerPC (except ar and ranlib; by Ian Taylor). | |
| 69 | ||
| 70 | * Support for Irix 5. | |
| 71 | ||
| 72 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked | |
| 73 | ELF output files, since BFD currently can't create them properly. | |
| 74 | ||
| 5c59269f | 75 | Changes in binutils 2.3: |
| 11548211 ILT |
76 | |
| 77 | * A new --stabs argument has been added to objdump to dump stabs sections in | |
| 78 | ELF and COFF files. | |
| 79 | ||
| 80 | * A new program, nlmconv, has been added. It can convert object files into | |
| 81 | Novell NetWare Loadable Modules. | |
| 82 | ||
| 83 | * The strings program has been added. | |
| 84 | ||
| 5c59269f | 85 | Changes in binutils 2.2: |
| 11548211 ILT |
86 | |
| 87 | * The 'copy' program has been renamed to 'objcopy', for consistency with | |
| 88 | 'objdump', and because 'copy' might more plausibly be used as a synonym for | |
| 89 | 'cp'. | |
| 90 | ||
| 91 | * The new stand-alone program c++filt is a filter that converts encoded | |
| 92 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This | |
| 93 | may get moved to the gcc distribution.) | |
| 94 | ||
| 95 | * nm -o on an archive now prefixes each line with the archive name, matching | |
| 96 | the output from BSD nm. | |
| 97 | ||
| 98 | * ar (and ld) can now read (but not write) BSD4.4-style archives. | |
| 99 | ||
| 100 | * New support for H8500, Z8000, and the Hitach SH. | |
| 101 | ||
| 102 | * Dis-assembler interface changed to allow sharing with gdb. | |
| 103 | ||
| 104 | * There is new Elf code, but it is not yet ready for general use. | |
| 105 | ||
| 106 | * There is the beginnings of a test suite. | |
| 107 | ||
| 5c59269f | 108 | Changes in binutils 2.1: |
| 11548211 ILT |
109 | |
| 110 | * There is now support for writing ECOFF files, so ld and the other utilities | |
| 111 | should work on Risc/Ultrix and Irix. Please let us know how well this works. | |
| 112 | ||
| 113 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD | |
| 114 | version), if there are any object files in the archive. So running ranlib is | |
| 115 | now redundant (unless the non-standard q command is used). This is required | |
| 116 | for Posix.2 conformance. | |
| 117 | ||
| 118 | * The archive-reading code now reads both BSD-style and SYSV-style archives | |
| 119 | independently of the selected target format. This is to encourage people to | |
| 120 | switch to SYSV-format, which has a number of advantages. | |
| 121 | ||
| 122 | * The strip and copy programs now have options to remove debug-symbols only | |
| 123 | and/or local symbols only. They now also support long options. | |
