12159047fSniklas-*- text -*- 22159047fSniklas 3*007c2a45Smiod* objcopy and strip can now take wildcard patterns in symbol names specified on 4*007c2a45Smiod the command line provided that the --wildcard switch is used to enable them. 5*007c2a45Smiod 6*007c2a45Smiod* readelf can now parse archives. 7*007c2a45Smiod 8*007c2a45Smiod* objdump now accepts --debugging-tags to print the debug information in a 9*007c2a45Smiod format compatible with ctags tool. 10*007c2a45Smiod 11*007c2a45Smiod* objcopy and strip now accept --only-keep-debug to create a file containing 12*007c2a45Smiod those sections that would be stripped out by --strip-debug. The idea is that 13*007c2a45Smiod this can be used in conjunction with the --add-gnu-debuglink switch to create 14*007c2a45Smiod a two part program distribution - one a stripped executable and the other the 15*007c2a45Smiod debugging info. 16*007c2a45Smiod 17*007c2a45Smiod* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink 18*007c2a45Smiod section into a (presumably stripped) executable. This allows the debug 19*007c2a45Smiod information for the file to be held in a separate file. 20*007c2a45Smiod 21*007c2a45Smiod* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX 22*007c2a45Smiod single-character representation. This can be checked by running nm 23*007c2a45Smiod with the -a switch. 24*007c2a45Smiod 25*007c2a45SmiodChanges in 2.14: 26*007c2a45Smiod 27c074d1c9Sdrahn* Added --info switch to objcopy and strip. 28c074d1c9Sdrahn 29c074d1c9Sdrahn* Support for Vitesse IQ2000 added by Red Hat. 30c074d1c9Sdrahn 31c074d1c9Sdrahn* Added 'S' encoding to strings to allow the display of 8-bit characters. 32c074d1c9Sdrahn 33c074d1c9Sdrahn* Added --prefix-symbols=<text>, --prefix-sections=<text> and 34c074d1c9Sdrahn --prefix-alloc-sections=<text> to objcopy. 35c074d1c9Sdrahn 36c074d1c9Sdrahn* readelf can handle the extensions to the DWARF2 spec used by the Unified 37c074d1c9Sdrahn Parallel C compiler. 38c074d1c9Sdrahn 39c074d1c9Sdrahn* BFD no longer declares a "boolean" type, to avoid clashes with other 40c074d1c9Sdrahn headers that declare the same. Users of BFD should replace boolean, 41c074d1c9Sdrahn false and true, with int, 0 and 1, or define their own boolean type. 42c074d1c9Sdrahn 43c074d1c9Sdrahn* Support for IP2K added by Denis Chertykov. 44c074d1c9Sdrahn 45c074d1c9SdrahnChanges in 2.13: 46c074d1c9Sdrahn 47c074d1c9Sdrahn* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 48c074d1c9Sdrahn and FR500 included. 49c074d1c9Sdrahn 50c074d1c9SdrahnChanges in version 2.12: 51c074d1c9Sdrahn 52c074d1c9Sdrahn* Support for Don Knuth's MMIX, by Hans-Peter Nilsson. 53c074d1c9Sdrahn 54c074d1c9Sdrahn* size: Add --totals to display summary of sizes (Berkeley format only). 55c074d1c9Sdrahn 56c074d1c9Sdrahn* readelf: Add --wide option to not break section header or segment listing 57c074d1c9Sdrahn lines to fit into 80 columns. 58c074d1c9Sdrahn 59c074d1c9Sdrahn* strings: Add --encoding to display wide character strings. By Markus Kuhn. 60c074d1c9Sdrahn 61c074d1c9Sdrahn* objcopy: Add --rename-section to change section names. 62c074d1c9Sdrahn 63c074d1c9Sdrahn* readelf: Support added for DWARF 2.1 extensions. Support added for 64c074d1c9Sdrahn displaying the contents of .debug.macinfo sections. 65c074d1c9Sdrahn 66b55d4692Sfgsch* New command line switches added to objcopy to allow symbols to be kept as 67b55d4692Sfgsch global symbols, and also to specify files containing lists of such symbols. 68b55d4692Sfgsch by Honda Hiroki. 69b55d4692Sfgsch 70c074d1c9Sdrahn* Support for OpenRISC by Johan Rydberg. 71c074d1c9Sdrahn 72c074d1c9Sdrahn* New command line switch to objcopy --alt-machine-code which creates a binary 73c074d1c9Sdrahn with an alternate machine code if one is defined in the architecture 74c074d1c9Sdrahn description. Only supported for ELF targets. By Alexandre Oliva. 75c074d1c9Sdrahn 76c074d1c9Sdrahn* New command line switch to objcopy -B (or --binary-architecture) which sets 77c074d1c9Sdrahn the architecture of the output file to the given argument. This option only 78c074d1c9Sdrahn makes sense, if the input target is binary. Otherwise it is ignored. 79c074d1c9Sdrahn By Stefan Geuken. 80c074d1c9Sdrahn 81c074d1c9Sdrahn* Support for PDP-11 by Lars Brinkhoff. 82c074d1c9Sdrahn 83b55d4692SfgschChanges in binutils 2.11: 84b55d4692Sfgsch 85b55d4692Sfgsch* Add support for ARM v5t and v5te architectures and Intel's XScale ARM 86b55d4692Sfgsch extenstions. 87b55d4692Sfgsch 88b55d4692Sfgsch* Add --srec-len and --srec-forceS3 command line switch to objcopy. 89b55d4692Sfgsch By Luciano Gemme. 90b55d4692Sfgsch 91b55d4692Sfgsch* Support for the MIPS32, by Anders Norlander. 92b55d4692Sfgsch 93b55d4692Sfgsch* Support for the i860, by Jason Eckhardt. 94b55d4692Sfgsch 95b55d4692Sfgsch* Support for CRIS (Axis Communications ETRAX series). 96b55d4692Sfgsch 97b305b0f1SespieChanges in binutils 2.10: 98b305b0f1Sespie 99b55d4692Sfgsch* Support for 64-bit ELF on HPPA. 100b55d4692Sfgsch 101b305b0f1Sespie* New command line switch to objdump --file-start-context which shows the 102b305b0f1Sespie entire file contents up to the source line first encountered for a given 103b305b0f1Sespie file. 104b305b0f1Sespie 105b305b0f1Sespie* New command line switch to objdump -M (or --disassembler-options) which takes 106b305b0f1Sespie a parameter which can then be interpreted on a per-target basis by the 107b305b0f1Sespie disassembler. Used by ARM targets to select register name sets, ISA, APCS or 108b305b0f1Sespie raw verions. 109b305b0f1Sespie 110b305b0f1Sespie* objdump support for -mi386:intel which causes disassembly to be displayed 111b305b0f1Sespie with intel syntax. 112b305b0f1Sespie 113b305b0f1Sespie* New program: readelf. This displays the contents of ELF format files, 114b305b0f1Sespie regardless of target machine. 115b305b0f1Sespie 116b305b0f1Sespie* objcopy now takes --change-section-lma, --change-section-vma, and 117b305b0f1Sespie --change-section-address options. The old --adjust-section-vma option is 118b305b0f1Sespie equivalent to --change-section-address. The other --adjust-* options are now 119b305b0f1Sespie renamed to --change-*, although --adjust-* continues to work. 120b305b0f1Sespie 121b305b0f1Sespie* objcopy has a --redefine-sym option that lets you rename symbols. 122b305b0f1Sespie 123b305b0f1Sespie* objcopy now takes a -j/--only-section option to copy only the specified 124b305b0f1Sespie sections. 125b305b0f1Sespie 126b305b0f1Sespie* dlltool now supports the IMPORTS command. 127b305b0f1Sespie 128b305b0f1Sespie* dlltool now takes --export-all-symbols, --no-export-all-symbols, 129b305b0f1Sespie --exclude-symbols, and --no-default-excludes options. 130b305b0f1Sespie 131b305b0f1SespieChanges in binutils 2.9: 132b305b0f1Sespie 133b305b0f1Sespie* Added windres program, which can be used to manipulate resources in WIN32 134b305b0f1Sespie files as used on Windows 95 and Windows NT. 135b305b0f1Sespie 136b305b0f1Sespie* The objcopy --gap-fill and --pad-to options operate on the LMA rather than 137b305b0f1Sespie the VMA of the sections. 138b305b0f1Sespie 139b305b0f1Sespie* Added S modifier to ar to not build a symbol table. 140b305b0f1Sespie 141b305b0f1SespieChanges in binutils 2.8: 142e93f7393Sniklas 143e93f7393Sniklas* The objdump disassembly format has been changed, and hopefully improved. Use 144b305b0f1Sespie the new --prefix-addresses option to get the old format. There are also new 145b305b0f1Sespie --disassemble-zeroes and --no-show-raw-insn options which affect disassembler 146b305b0f1Sespie output. 147e93f7393Sniklas 148e93f7393Sniklas* Formats may now be specified as configuration triplets. For example, 149e93f7393Sniklas objdump -b i386-pc-linux. The triplets are not passed through config.sub, 150e93f7393Sniklas so they must be in canonical form. 151e93f7393Sniklas 152b305b0f1Sespie* Added new addr2line program. This uses the debugging information to convert 153b305b0f1Sespie an address into a file name and line number within a program. 154b305b0f1Sespie 155e93f7393Sniklas* Added --change-leading-char argument to objcopy. 156e93f7393Sniklas 157b305b0f1Sespie* Added --weaken argument to objcopy. 158b305b0f1Sespie 159b305b0f1Sespie* objdump --dynamic-reloc now works on ELF executables and shared libraries. 160b305b0f1Sespie 161b305b0f1Sespie* Added --adjust-vma option to objdump. 162b305b0f1Sespie 163b305b0f1Sespie* Added -C/--demangle option to objdump. 164b305b0f1Sespie 165b305b0f1Sespie* Added -p/--preserve-dates option to strip and objcopy. 166b305b0f1Sespie 167b305b0f1SespieChanges in binutils 2.7: 168c88b1d6cSniklas 169c88b1d6cSniklas* Added --enable-shared and --enable-commonbfdlib options to configure. 170c88b1d6cSniklas 171c88b1d6cSniklas* Added --debugging argument to objdump and objcopy. 172c88b1d6cSniklas 173c88b1d6cSniklas* Added --defined-only argument to nm. 174c88b1d6cSniklas 175c88b1d6cSniklas* Added --remove-leading-char argument to objcopy. 176c88b1d6cSniklas 1770c6d0228Sniklas* The objdump --line-numbers option is now meaningful with --reloc. 1780c6d0228Sniklas 1790c6d0228Sniklas* Added --line-numbers option to nm. 1800c6d0228Sniklas 1810c6d0228Sniklas* Added --endian/-EB/-EL option to objdump. 1820c6d0228Sniklas 1830c6d0228Sniklas* Added support for Alpha OpenVMS/AXP. 1840c6d0228Sniklas 185b305b0f1SespieChanges in binutils 2.6: 1862159047fSniklas 1872159047fSniklas* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. 1882159047fSniklas 1892159047fSniklas* Added several arguments to objcopy to provide some control over how the new 1902159047fSniklas file is laid out in memory. Also added binary output format to BFD to permit 1912159047fSniklas generating plain binary files. 1922159047fSniklas 1932159047fSniklas* Added --start-address and --stop-address options to objdump. 1942159047fSniklas 1952159047fSniklas* ar and ranlib now work on AIX. The tools are now built by default on AIX. 1962159047fSniklas 197b305b0f1SespieChanges in binutils 2.5: 1982159047fSniklas 1992159047fSniklas* Changed objdump -dr to dump the relocs interspersed with the assembly 200*007c2a45Smiod listing, for a more useful listing of relocatable files. 2012159047fSniklas 2022159047fSniklas* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. 2032159047fSniklas Added -D/--disassemble-all option to disassemble all sections. 2042159047fSniklas 2052159047fSniklas* Added --size-sort option to nm. 2062159047fSniklas 2072159047fSniklas* strip and objcopy should now be able to handle dynamically linked ELF 2082159047fSniklas executables. 2092159047fSniklas 210b305b0f1SespieChanges in binutils 2.4: 2112159047fSniklas 2122159047fSniklas* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and 2132159047fSniklas PowerPC (except ar and ranlib; by Ian Taylor). 2142159047fSniklas 2152159047fSniklas* Support for Irix 5. 2162159047fSniklas 2172159047fSniklas* Programs `strip' and `objcopy' will not attempt to write dynamically linked 2182159047fSniklas ELF output files, since BFD currently can't create them properly. 2192159047fSniklas 220b305b0f1SespieChanges in binutils 2.3: 2212159047fSniklas 2222159047fSniklas* A new --stabs argument has been added to objdump to dump stabs sections in 2232159047fSniklas ELF and COFF files. 2242159047fSniklas 2252159047fSniklas* A new program, nlmconv, has been added. It can convert object files into 2262159047fSniklas Novell NetWare Loadable Modules. 2272159047fSniklas 2282159047fSniklas* The strings program has been added. 2292159047fSniklas 230b305b0f1SespieChanges in binutils 2.2: 2312159047fSniklas 2322159047fSniklas* The 'copy' program has been renamed to 'objcopy', for consistency with 2332159047fSniklas 'objdump', and because 'copy' might more plausibly be used as a synonym for 2342159047fSniklas 'cp'. 2352159047fSniklas 2362159047fSniklas* The new stand-alone program c++filt is a filter that converts encoded 2372159047fSniklas (mangled) C++ assembly-level identifiers to user-level names. (Note: This 2382159047fSniklas may get moved to the gcc distribution.) 2392159047fSniklas 2402159047fSniklas* nm -o on an archive now prefixes each line with the archive name, matching 2412159047fSniklas the output from BSD nm. 2422159047fSniklas 2432159047fSniklas* ar (and ld) can now read (but not write) BSD4.4-style archives. 2442159047fSniklas 2452159047fSniklas* New support for H8500, Z8000, and the Hitach SH. 2462159047fSniklas 2472159047fSniklas* Dis-assembler interface changed to allow sharing with gdb. 2482159047fSniklas 2492159047fSniklas* There is new Elf code, but it is not yet ready for general use. 2502159047fSniklas 2512159047fSniklas* There is the beginnings of a test suite. 2522159047fSniklas 253b305b0f1SespieChanges in binutils 2.1: 2542159047fSniklas 2552159047fSniklas* There is now support for writing ECOFF files, so ld and the other utilities 2562159047fSniklas should work on Risc/Ultrix and Irix. Please let us know how well this works. 2572159047fSniklas 2582159047fSniklas* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD 2592159047fSniklas version), if there are any object files in the archive. So running ranlib is 2602159047fSniklas now redundant (unless the non-standard q command is used). This is required 2612159047fSniklas for Posix.2 conformance. 2622159047fSniklas 2632159047fSniklas* The archive-reading code now reads both BSD-style and SYSV-style archives 2642159047fSniklas independently of the selected target format. This is to encourage people to 2652159047fSniklas switch to SYSV-format, which has a number of advantages. 2662159047fSniklas 2672159047fSniklas* The strip and copy programs now have options to remove debug-symbols only 2682159047fSniklas and/or local symbols only. They now also support long options. 2692159047fSniklas 2702159047fSniklas 2712159047fSniklasLocal variables: 2722159047fSniklasfill-column: 79 2732159047fSniklasEnd: 274
