133965Sjdp-*- text -*- 233965Sjdp 360484SobrienChanges in binutils 2.10: 460484Sobrien 560484Sobrien* New command line switch to objdump --file-start-context which shows the 660484Sobrien entire file contents up to the source line first encountered for a given 760484Sobrien file. 860484Sobrien 960484Sobrien* New command line switch to objdump -M (or --disassembler-options) which takes 1060484Sobrien a parameter which can then be interpreted on a per-target basis by the 1160484Sobrien disassembler. Used by ARM targets to select register name sets, ISA, APCS or 1260484Sobrien raw verions. 1360484Sobrien 1460484Sobrien* objdump support for -mi386:intel which causes disassembly to be displayed 1560484Sobrien with intel syntax. 1660484Sobrien 1760484Sobrien* New program: readelf. This displays the contents of ELF format files, 1860484Sobrien regardless of target machine. 1960484Sobrien 2060484Sobrien* objcopy now takes --change-section-lma, --change-section-vma, and 2160484Sobrien --change-section-address options. The old --adjust-section-vma option is 2260484Sobrien equivalent to --change-section-address. The other --adjust-* options are now 2360484Sobrien renamed to --change-*, although --adjust-* continues to work. 2460484Sobrien 2560484Sobrien* objcopy has a --redefine-sym option that lets you rename symbols. 2660484Sobrien 2760484Sobrien* objcopy now takes a -j/--only-section option to copy only the specified 2860484Sobrien sections. 2960484Sobrien 3060484Sobrien* dlltool now supports the IMPORTS command. 3160484Sobrien 3260484Sobrien* dlltool now takes --export-all-symbols, --no-export-all-symbols, 3360484Sobrien --exclude-symbols, and --no-default-excludes options. 3460484Sobrien 3538889SjdpChanges in binutils 2.9: 3638889Sjdp 3738889Sjdp* Added windres program, which can be used to manipulate resources in WIN32 3838889Sjdp files as used on Windows 95 and Windows NT. 3938889Sjdp 4038889Sjdp* The objcopy --gap-fill and --pad-to options operate on the LMA rather than 4138889Sjdp the VMA of the sections. 4238889Sjdp 4338889Sjdp* Added S modifier to ar to not build a symbol table. 4438889Sjdp 4533965SjdpChanges in binutils 2.8: 4633965Sjdp 4733965Sjdp* The objdump disassembly format has been changed, and hopefully improved. Use 4833965Sjdp the new --prefix-addresses option to get the old format. There are also new 4933965Sjdp --disassemble-zeroes and --no-show-raw-insn options which affect disassembler 5033965Sjdp output. 5133965Sjdp 5233965Sjdp* Formats may now be specified as configuration triplets. For example, 5333965Sjdp objdump -b i386-pc-linux. The triplets are not passed through config.sub, 5433965Sjdp so they must be in canonical form. 5533965Sjdp 5633965Sjdp* Added new addr2line program. This uses the debugging information to convert 5733965Sjdp an address into a file name and line number within a program. 5833965Sjdp 5933965Sjdp* Added --change-leading-char argument to objcopy. 6033965Sjdp 6133965Sjdp* Added --weaken argument to objcopy. 6233965Sjdp 6333965Sjdp* objdump --dynamic-reloc now works on ELF executables and shared libraries. 6433965Sjdp 6533965Sjdp* Added --adjust-vma option to objdump. 6633965Sjdp 6733965Sjdp* Added -C/--demangle option to objdump. 6833965Sjdp 6933965Sjdp* Added -p/--preserve-dates option to strip and objcopy. 7033965Sjdp 7133965SjdpChanges in binutils 2.7: 7233965Sjdp 7333965Sjdp* Added --enable-shared and --enable-commonbfdlib options to configure. 7433965Sjdp 7533965Sjdp* Added --debugging argument to objdump and objcopy. 7633965Sjdp 7733965Sjdp* Added --defined-only argument to nm. 7833965Sjdp 7933965Sjdp* Added --remove-leading-char argument to objcopy. 8033965Sjdp 8133965Sjdp* The objdump --line-numbers option is now meaningful with --reloc. 8233965Sjdp 8333965Sjdp* Added --line-numbers option to nm. 8433965Sjdp 8533965Sjdp* Added --endian/-EB/-EL option to objdump. 8633965Sjdp 8733965Sjdp* Added support for Alpha OpenVMS/AXP. 8833965Sjdp 8933965SjdpChanges in binutils 2.6: 9033965Sjdp 9133965Sjdp* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. 9233965Sjdp 9333965Sjdp* Added several arguments to objcopy to provide some control over how the new 9433965Sjdp file is laid out in memory. Also added binary output format to BFD to permit 9533965Sjdp generating plain binary files. 9633965Sjdp 9733965Sjdp* Added --start-address and --stop-address options to objdump. 9833965Sjdp 9933965Sjdp* ar and ranlib now work on AIX. The tools are now built by default on AIX. 10033965Sjdp 10133965SjdpChanges in binutils 2.5: 10233965Sjdp 10333965Sjdp* Changed objdump -dr to dump the relocs interspersed with the assembly 10433965Sjdp listing, for a more useful listing of relocateable files. 10533965Sjdp 10633965Sjdp* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. 10733965Sjdp Added -D/--disassemble-all option to disassemble all sections. 10833965Sjdp 10933965Sjdp* Added --size-sort option to nm. 11033965Sjdp 11133965Sjdp* strip and objcopy should now be able to handle dynamically linked ELF 11233965Sjdp executables. 11333965Sjdp 11433965SjdpChanges in binutils 2.4: 11533965Sjdp 11633965Sjdp* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and 11733965Sjdp PowerPC (except ar and ranlib; by Ian Taylor). 11833965Sjdp 11933965Sjdp* Support for Irix 5. 12033965Sjdp 12133965Sjdp* Programs `strip' and `objcopy' will not attempt to write dynamically linked 12233965Sjdp ELF output files, since BFD currently can't create them properly. 12333965Sjdp 12433965SjdpChanges in binutils 2.3: 12533965Sjdp 12633965Sjdp* A new --stabs argument has been added to objdump to dump stabs sections in 12733965Sjdp ELF and COFF files. 12833965Sjdp 12933965Sjdp* A new program, nlmconv, has been added. It can convert object files into 13033965Sjdp Novell NetWare Loadable Modules. 13133965Sjdp 13233965Sjdp* The strings program has been added. 13333965Sjdp 13433965SjdpChanges in binutils 2.2: 13533965Sjdp 13633965Sjdp* The 'copy' program has been renamed to 'objcopy', for consistency with 13733965Sjdp 'objdump', and because 'copy' might more plausibly be used as a synonym for 13833965Sjdp 'cp'. 13933965Sjdp 14033965Sjdp* The new stand-alone program c++filt is a filter that converts encoded 14133965Sjdp (mangled) C++ assembly-level identifiers to user-level names. (Note: This 14233965Sjdp may get moved to the gcc distribution.) 14333965Sjdp 14433965Sjdp* nm -o on an archive now prefixes each line with the archive name, matching 14533965Sjdp the output from BSD nm. 14633965Sjdp 14733965Sjdp* ar (and ld) can now read (but not write) BSD4.4-style archives. 14833965Sjdp 14933965Sjdp* New support for H8500, Z8000, and the Hitach SH. 15033965Sjdp 15133965Sjdp* Dis-assembler interface changed to allow sharing with gdb. 15233965Sjdp 15333965Sjdp* There is new Elf code, but it is not yet ready for general use. 15433965Sjdp 15533965Sjdp* There is the beginnings of a test suite. 15633965Sjdp 15733965SjdpChanges in binutils 2.1: 15833965Sjdp 15933965Sjdp* There is now support for writing ECOFF files, so ld and the other utilities 16033965Sjdp should work on Risc/Ultrix and Irix. Please let us know how well this works. 16133965Sjdp 16233965Sjdp* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD 16333965Sjdp version), if there are any object files in the archive. So running ranlib is 16433965Sjdp now redundant (unless the non-standard q command is used). This is required 16533965Sjdp for Posix.2 conformance. 16633965Sjdp 16733965Sjdp* The archive-reading code now reads both BSD-style and SYSV-style archives 16833965Sjdp independently of the selected target format. This is to encourage people to 16933965Sjdp switch to SYSV-format, which has a number of advantages. 17033965Sjdp 17133965Sjdp* The strip and copy programs now have options to remove debug-symbols only 17233965Sjdp and/or local symbols only. They now also support long options. 17333965Sjdp 17433965Sjdp 17533965SjdpLocal variables: 17633965Sjdpfill-column: 79 17733965SjdpEnd: 178
