| 3 | * readelf: Add --wide option to not break section header or segment listing |
| 4 | lines to fit into 80 columns. |
| 5 | |
| 6 | * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
| 7 | |
| 8 | * objcopy: Add --rename-section to change section names. |
| 9 | |
| 10 | * readelf: Support added for DWARF 2.1 extensions. Support added for |
| 11 | displaying the contents of .debug.macinfo sections. |
| 12 | |
| 13 | * New command line switches added to objcopy to allow symbols to be kept as |
| 14 | global symbols, and also to specify files containing lists of such symbols. |
| 15 | by Honda Hiroki. |
| 16 | |
| 17 | * Support for OpenRISC by Johan Rydberg. |
| 18 | |
| 19 | * New command line switch to objcopy --alt-machine-code which creates a binary |
| 20 | with an alternate machine code if one is defined in the architecture |
| 21 | description. Only supported for ELF targets. By Alexandre Oliva. |
| 22 | |
| 23 | * New command line switch to objcopy -B (or --binary-architecture) which sets |
| 24 | the architecture of the output file to the given argument. This option only |
| 25 | makes sense, if the input target is binary. Otherwise it is ignored. |
| 26 | By Stefan Geuken. |
| 27 | |
| 28 | * Support for PDP-11 by Lars Brinkhoff. |
| 29 | |
| 30 | Changes in binutils 2.11: |
| 31 | |
| 32 | * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
| 33 | extenstions. |
| 34 | |
| 35 | * Add --srec-len and --srec-forceS3 command line switch to objcopy. |
| 36 | By Luciano Gemme. |
| 37 | |
| 38 | * Support for the MIPS32, by Anders Norlander. |
| 39 | |
| 40 | * Support for the i860, by Jason Eckhardt. |
| 41 | |
| 42 | * Support for CRIS (Axis Communications ETRAX series). |
| 43 | |
| 44 | Changes in binutils 2.10: |
| 45 | |
| 46 | * Support for 64-bit ELF on HPPA. |
| 47 | |
| 48 | * New command line switch to objdump --file-start-context which shows the |
| 49 | entire file contents up to the source line first encountered for a given |
| 50 | file. |
| 51 | |
| 52 | * New command line switch to objdump -M (or --disassembler-options) which takes |
| 53 | a parameter which can then be interpreted on a per-target basis by the |
| 54 | disassembler. Used by ARM targets to select register name sets, ISA, APCS or |
| 55 | raw verions. |
| 56 | |
| 57 | * objdump support for -mi386:intel which causes disassembly to be displayed |
| 58 | with intel syntax. |
| 59 | |
| 60 | * New program: readelf. This displays the contents of ELF format files, |
| 61 | regardless of target machine. |
| 62 | |
| 63 | * objcopy now takes --change-section-lma, --change-section-vma, and |
| 64 | --change-section-address options. The old --adjust-section-vma option is |
| 65 | equivalent to --change-section-address. The other --adjust-* options are now |
| 66 | renamed to --change-*, although --adjust-* continues to work. |
| 67 | |
| 68 | * objcopy has a --redefine-sym option that lets you rename symbols. |
| 69 | |
| 70 | * objcopy now takes a -j/--only-section option to copy only the specified |
| 71 | sections. |
| 72 | |
| 73 | * dlltool now supports the IMPORTS command. |
| 74 | |
| 75 | * dlltool now takes --export-all-symbols, --no-export-all-symbols, |
| 76 | --exclude-symbols, and --no-default-excludes options. |
| 77 | |
| 78 | Changes in binutils 2.9: |
| 79 | |
| 80 | * Added windres program, which can be used to manipulate resources in WIN32 |
| 81 | files as used on Windows 95 and Windows NT. |
| 82 | |
| 83 | * The objcopy --gap-fill and --pad-to options operate on the LMA rather than |
| 84 | the VMA of the sections. |
| 85 | |
| 86 | * Added S modifier to ar to not build a symbol table. |
| 87 | |
| 88 | Changes in binutils 2.8: |
| 89 | |
| 90 | * The objdump disassembly format has been changed, and hopefully improved. Use |
| 91 | the new --prefix-addresses option to get the old format. There are also new |
| 92 | --disassemble-zeroes and --no-show-raw-insn options which affect disassembler |
| 93 | output. |
| 94 | |
| 95 | * Formats may now be specified as configuration triplets. For example, |
| 96 | objdump -b i386-pc-linux. The triplets are not passed through config.sub, |
| 97 | so they must be in canonical form. |
| 98 | |
| 99 | * Added new addr2line program. This uses the debugging information to convert |
| 100 | an address into a file name and line number within a program. |
| 101 | |
| 102 | * Added --change-leading-char argument to objcopy. |
| 103 | |
| 104 | * Added --weaken argument to objcopy. |
| 105 | |
| 106 | * objdump --dynamic-reloc now works on ELF executables and shared libraries. |
| 107 | |
| 108 | * Added --adjust-vma option to objdump. |
| 109 | |
| 110 | * Added -C/--demangle option to objdump. |
| 111 | |
| 112 | * Added -p/--preserve-dates option to strip and objcopy. |
| 113 | |
| 114 | Changes in binutils 2.7: |
| 115 | |
| 116 | * Added --enable-shared and --enable-commonbfdlib options to configure. |
| 117 | |
| 118 | * Added --debugging argument to objdump and objcopy. |
| 119 | |
| 120 | * Added --defined-only argument to nm. |
| 121 | |
| 122 | * Added --remove-leading-char argument to objcopy. |
| 123 | |
| 124 | * The objdump --line-numbers option is now meaningful with --reloc. |
| 125 | |
| 126 | * Added --line-numbers option to nm. |
| 127 | |
| 128 | * Added --endian/-EB/-EL option to objdump. |
| 129 | |
| 130 | * Added support for Alpha OpenVMS/AXP. |
| 131 | |
| 132 | Changes in binutils 2.6: |
| 133 | |
| 134 | * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. |
| 135 | |
| 136 | * Added several arguments to objcopy to provide some control over how the new |
| 137 | file is laid out in memory. Also added binary output format to BFD to permit |
| 138 | generating plain binary files. |
| 139 | |
| 140 | * Added --start-address and --stop-address options to objdump. |
| 141 | |
| 142 | * ar and ranlib now work on AIX. The tools are now built by default on AIX. |
| 143 | |
| 144 | Changes in binutils 2.5: |
| 145 | |
| 146 | * Changed objdump -dr to dump the relocs interspersed with the assembly |
| 147 | listing, for a more useful listing of relocateable files. |
| 148 | |
| 149 | * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. |
| 150 | Added -D/--disassemble-all option to disassemble all sections. |
| 151 | |
| 152 | * Added --size-sort option to nm. |
| 153 | |
| 154 | * strip and objcopy should now be able to handle dynamically linked ELF |
| 155 | executables. |
| 156 | |
| 157 | Changes in binutils 2.4: |
| 158 | |
| 159 | * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and |
| 160 | PowerPC (except ar and ranlib; by Ian Taylor). |
| 161 | |
| 162 | * Support for Irix 5. |
| 163 | |
| 164 | * Programs `strip' and `objcopy' will not attempt to write dynamically linked |
| 165 | ELF output files, since BFD currently can't create them properly. |
| 166 | |
| 167 | Changes in binutils 2.3: |
| 168 | |
| 169 | * A new --stabs argument has been added to objdump to dump stabs sections in |
| 170 | ELF and COFF files. |
| 171 | |
| 172 | * A new program, nlmconv, has been added. It can convert object files into |
| 173 | Novell NetWare Loadable Modules. |
| 174 | |
| 175 | * The strings program has been added. |
| 176 | |
| 177 | Changes in binutils 2.2: |
| 178 | |
| 179 | * The 'copy' program has been renamed to 'objcopy', for consistency with |
| 180 | 'objdump', and because 'copy' might more plausibly be used as a synonym for |
| 181 | 'cp'. |
| 182 | |
| 183 | * The new stand-alone program c++filt is a filter that converts encoded |
| 184 | (mangled) C++ assembly-level identifiers to user-level names. (Note: This |
| 185 | may get moved to the gcc distribution.) |
| 186 | |
| 187 | * nm -o on an archive now prefixes each line with the archive name, matching |
| 188 | the output from BSD nm. |
| 189 | |
| 190 | * ar (and ld) can now read (but not write) BSD4.4-style archives. |
| 191 | |
| 192 | * New support for H8500, Z8000, and the Hitach SH. |
| 193 | |
| 194 | * Dis-assembler interface changed to allow sharing with gdb. |
| 195 | |
| 196 | * There is new Elf code, but it is not yet ready for general use. |
| 197 | |
| 198 | * There is the beginnings of a test suite. |
| 199 | |
| 200 | Changes in binutils 2.1: |
| 201 | |
| 202 | * There is now support for writing ECOFF files, so ld and the other utilities |
| 203 | should work on Risc/Ultrix and Irix. Please let us know how well this works. |
| 204 | |
| 205 | * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD |
| 206 | version), if there are any object files in the archive. So running ranlib is |
| 207 | now redundant (unless the non-standard q command is used). This is required |
| 208 | for Posix.2 conformance. |
| 209 | |
| 210 | * The archive-reading code now reads both BSD-style and SYSV-style archives |
| 211 | independently of the selected target format. This is to encourage people to |
| 212 | switch to SYSV-format, which has a number of advantages. |
| 213 | |
| 214 | * The strip and copy programs now have options to remove debug-symbols only |
| 215 | and/or local symbols only. They now also support long options. |
