133965Sjdp-*- text -*- 2130561Sobrien 3218822Sdim* A new tool "windmc" has been added for some targets. This is a message 4218822Sdim compiler which attempts to be compatible with the MS version. 5218822Sdim 6218822Sdim* Add codepage support to the windres tool. It now supports many new 7218822Sdim resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation 8218822Sdim for binary files is done now via bfd itself. The endianess problems 9218822Sdim for different hosts are solved. Dumps of .res files can now be 10218822Sdim re-compiled by windres without lossing resources or compilation errors. 11218822Sdim Some problems on dialog resource translations are corrected. 12218822Sdim 13218822Sdim* Add --extract-symbol command line option to objcopy, which will 14218822Sdim strip everything out of an ordinary object file or executable except 15218822Sdim for its symbol table. Files containing just symbols can be useful 16218822Sdim to some OSes. 17218822Sdim 18218822Sdim* Add "-x NAME" to readelf in addition to "-x NUMBER". 19218822Sdim 20218822Sdim* Add -i and -t switches to cxxfilt. -i disables the display of implementation 21218822Sdim specific extra demangling information (if any) and -t disables the demangling 22218822Sdim of types. 23218822Sdim 24218822Sdim* Add support for the "@<file>" syntax to the command lines of all tools, so 25218822Sdim that extra switches can be read from <file>. 26218822Sdim 27218822Sdim* Add "-W/--dwarf" to objdump to display the contents of the DWARF 28218822Sdim debug sections. 29218822Sdim 30218822Sdim* Add "-t/--section-details" to readelf to display section details. 31218822Sdim "-N/--full-section-name" is deprecated. 32218822Sdim 33218822Sdim* powerpc-linux ld now supports a variant form of PLT and GOT for the security 34218822Sdim conscious. This form will automatically be chosen when ld detects that all 35218822Sdim code in regular object files was generated by gcc -msecure-plt. The old PLT 36218822Sdim and GOT may be forced by a new ld option, --bss-plt. 37218822Sdim 38218822Sdim* Add "-i/--inlines" to addr2line to print enclosing scope information 39218822Sdim for inlined function chains, back to first non-inlined function. 40218822Sdim 41218822Sdim* Add "-N/--full-section-name" to readelf to display full section name. 42218822Sdim 43218822Sdim* Add "-M entry:<addr>" switch to objdump to specify a function entry address 44218822Sdim when disassembling VAX binaries. 45218822Sdim 46218822Sdim* Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches 47218822Sdim to objcopy to convert local symbols into global symbols. 48218822Sdim 49218822Sdim* gprof now allows input files to have histogram records for 50218822Sdim several memory ranges, provided those ranges are disjoint. 51218822Sdim 52218822SdimChanges in 2.16: 53218822Sdim 54218822Sdim* Add "-g/--section-groups" to readelf to display section groups. 55218822Sdim 56218822Sdim* objcopy recognizes two new options --strip-unneeded-symbol and 57218822Sdim --strip-unneeded-symbols, namely for use together with the wildcard 58218822Sdim matching the original --strip-symbol/--strip-symbols provided, but 59218822Sdim retaining any symbols matching but needed by relocations. 60218822Sdim 61218822Sdim* readelf can now display address ranges from .debug_range sections. This 62218822Sdim happens automatically when a DW_AT_range attribute is encountered. The 63218822Sdim command line switch --debug-dump=Ranges (or -wR) can also be used to display 64218822Sdim the contents of the .debug_range section. 65218822Sdim 66218822Sdim* nm and objdump now have a switch "--special-syms" to enable the displaying of 67218822Sdim symbols which the target considers to be special. By default these symbols 68218822Sdim are no longer displayed. Currently the only special symbols are the Mapping 69218822Sdim symbols used by the ARM port to mark transitions between text and data and 70218822Sdim between ARM and THUMB code. 71218822Sdim 72218822Sdim* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional 73218822Sdim import and export symbols with <preifx> prepended to them. 74218822Sdim 75218822SdimChanges in 2.15: 76218822Sdim 77218822Sdim* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the 78218822Sdim disassembler to print the "raw" mips instruction mnemonic instead of some 79218822Sdim pseudo instruction name. I.E. print "daddu" or "or" instead of "move", 80218822Sdim "sll" instead of "nop", etc. 81218822Sdim 82130561Sobrien* objcopy and strip can now take wildcard patterns in symbol names specified on 83130561Sobrien the command line provided that the --wildcard switch is used to enable them. 84130561Sobrien 85130561Sobrien* readelf can now parse archives. 86130561Sobrien 87130561Sobrien* objdump now accepts --debugging-tags to print the debug information in a 88130561Sobrien format compatible with ctags tool. 89130561Sobrien 90130561Sobrien* objcopy and strip now accept --only-keep-debug to create a file containing 91130561Sobrien those sections that would be stripped out by --strip-debug. The idea is that 92130561Sobrien this can be used in conjunction with the --add-gnu-debuglink switch to create 93130561Sobrien a two part program distribution - one a stripped executable and the other the 94130561Sobrien debugging info. 95130561Sobrien 96130561Sobrien* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink 97130561Sobrien section into a (presumably stripped) executable. This allows the debug 98130561Sobrien information for the file to be held in a separate file. 99130561Sobrien 100130561Sobrien* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX 101130561Sobrien single-character representation. This can be checked by running nm 102130561Sobrien with the -a switch. 103130561Sobrien 104130561SobrienChanges in 2.14: 105130561Sobrien 106130561Sobrien* Added --info switch to objcopy and strip. 107130561Sobrien 108130561Sobrien* Support for Vitesse IQ2000 added by Red Hat. 109130561Sobrien 110130561Sobrien* Added 'S' encoding to strings to allow the display of 8-bit characters. 111130561Sobrien 112130561Sobrien* Added --prefix-symbols=<text>, --prefix-sections=<text> and 113130561Sobrien --prefix-alloc-sections=<text> to objcopy. 114130561Sobrien 115130561Sobrien* readelf can handle the extensions to the DWARF2 spec used by the Unified 116130561Sobrien Parallel C compiler. 117130561Sobrien 118130561Sobrien* BFD no longer declares a "boolean" type, to avoid clashes with other 119130561Sobrien headers that declare the same. Users of BFD should replace boolean, 120130561Sobrien false and true, with int, 0 and 1, or define their own boolean type. 121130561Sobrien 122130561Sobrien* Support for IP2K added by Denis Chertykov. 123130561Sobrien 124104834SobrienChanges in 2.13: 12533965Sjdp 126104834Sobrien* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 127104834Sobrien and FR500 included. 12892828Sobrien 129104834SobrienChanges in version 2.12: 130104834Sobrien 13191041Sobrien* Support for Don Knuth's MMIX, by Hans-Peter Nilsson. 13291041Sobrien 13389857Sobrien* size: Add --totals to display summary of sizes (Berkeley format only). 13489857Sobrien 13589857Sobrien* readelf: Add --wide option to not break section header or segment listing 13689857Sobrien lines to fit into 80 columns. 13789857Sobrien 13889857Sobrien* strings: Add --encoding to display wide character strings. By Markus Kuhn. 13989857Sobrien 14089857Sobrien* objcopy: Add --rename-section to change section names. 14189857Sobrien 14289857Sobrien* readelf: Support added for DWARF 2.1 extensions. Support added for 14389857Sobrien displaying the contents of .debug.macinfo sections. 14489857Sobrien 14578828Sobrien* New command line switches added to objcopy to allow symbols to be kept as 14678828Sobrien global symbols, and also to specify files containing lists of such symbols. 14778828Sobrien by Honda Hiroki. 14878828Sobrien 14989857Sobrien* Support for OpenRISC by Johan Rydberg. 15089857Sobrien 15189857Sobrien* New command line switch to objcopy --alt-machine-code which creates a binary 15289857Sobrien with an alternate machine code if one is defined in the architecture 15389857Sobrien description. Only supported for ELF targets. By Alexandre Oliva. 15489857Sobrien 15589857Sobrien* New command line switch to objcopy -B (or --binary-architecture) which sets 15689857Sobrien the architecture of the output file to the given argument. This option only 15789857Sobrien makes sense, if the input target is binary. Otherwise it is ignored. 15889857Sobrien By Stefan Geuken. 15989857Sobrien 16089857Sobrien* Support for PDP-11 by Lars Brinkhoff. 16189857Sobrien 16278828SobrienChanges in binutils 2.11: 16378828Sobrien 16477298Sobrien* Add support for ARM v5t and v5te architectures and Intel's XScale ARM 16577298Sobrien extenstions. 16677298Sobrien 16777298Sobrien* Add --srec-len and --srec-forceS3 command line switch to objcopy. 16877298Sobrien By Luciano Gemme. 169130561Sobrien 17077298Sobrien* Support for the MIPS32, by Anders Norlander. 17177298Sobrien 17277298Sobrien* Support for the i860, by Jason Eckhardt. 17377298Sobrien 17477298Sobrien* Support for CRIS (Axis Communications ETRAX series). 17577298Sobrien 17660484SobrienChanges in binutils 2.10: 17760484Sobrien 17878828Sobrien* Support for 64-bit ELF on HPPA. 17978828Sobrien 18060484Sobrien* New command line switch to objdump --file-start-context which shows the 18160484Sobrien entire file contents up to the source line first encountered for a given 182130561Sobrien file. 18360484Sobrien 18460484Sobrien* New command line switch to objdump -M (or --disassembler-options) which takes 18560484Sobrien a parameter which can then be interpreted on a per-target basis by the 18660484Sobrien disassembler. Used by ARM targets to select register name sets, ISA, APCS or 18760484Sobrien raw verions. 188130561Sobrien 18960484Sobrien* objdump support for -mi386:intel which causes disassembly to be displayed 19060484Sobrien with intel syntax. 19160484Sobrien 19260484Sobrien* New program: readelf. This displays the contents of ELF format files, 19360484Sobrien regardless of target machine. 19460484Sobrien 19560484Sobrien* objcopy now takes --change-section-lma, --change-section-vma, and 19660484Sobrien --change-section-address options. The old --adjust-section-vma option is 19760484Sobrien equivalent to --change-section-address. The other --adjust-* options are now 19860484Sobrien renamed to --change-*, although --adjust-* continues to work. 19960484Sobrien 20060484Sobrien* objcopy has a --redefine-sym option that lets you rename symbols. 20160484Sobrien 20260484Sobrien* objcopy now takes a -j/--only-section option to copy only the specified 20360484Sobrien sections. 20460484Sobrien 20560484Sobrien* dlltool now supports the IMPORTS command. 20660484Sobrien 20760484Sobrien* dlltool now takes --export-all-symbols, --no-export-all-symbols, 20860484Sobrien --exclude-symbols, and --no-default-excludes options. 20960484Sobrien 21038889SjdpChanges in binutils 2.9: 21138889Sjdp 21238889Sjdp* Added windres program, which can be used to manipulate resources in WIN32 21338889Sjdp files as used on Windows 95 and Windows NT. 21438889Sjdp 21538889Sjdp* The objcopy --gap-fill and --pad-to options operate on the LMA rather than 21638889Sjdp the VMA of the sections. 21738889Sjdp 21838889Sjdp* Added S modifier to ar to not build a symbol table. 21938889Sjdp 22033965SjdpChanges in binutils 2.8: 22133965Sjdp 22233965Sjdp* The objdump disassembly format has been changed, and hopefully improved. Use 22333965Sjdp the new --prefix-addresses option to get the old format. There are also new 22433965Sjdp --disassemble-zeroes and --no-show-raw-insn options which affect disassembler 22533965Sjdp output. 22633965Sjdp 22733965Sjdp* Formats may now be specified as configuration triplets. For example, 22833965Sjdp objdump -b i386-pc-linux. The triplets are not passed through config.sub, 22933965Sjdp so they must be in canonical form. 23033965Sjdp 23133965Sjdp* Added new addr2line program. This uses the debugging information to convert 23233965Sjdp an address into a file name and line number within a program. 23333965Sjdp 23433965Sjdp* Added --change-leading-char argument to objcopy. 23533965Sjdp 23633965Sjdp* Added --weaken argument to objcopy. 23733965Sjdp 23833965Sjdp* objdump --dynamic-reloc now works on ELF executables and shared libraries. 23933965Sjdp 24033965Sjdp* Added --adjust-vma option to objdump. 24133965Sjdp 24233965Sjdp* Added -C/--demangle option to objdump. 24333965Sjdp 24433965Sjdp* Added -p/--preserve-dates option to strip and objcopy. 24533965Sjdp 24633965SjdpChanges in binutils 2.7: 24733965Sjdp 24833965Sjdp* Added --enable-shared and --enable-commonbfdlib options to configure. 24933965Sjdp 25033965Sjdp* Added --debugging argument to objdump and objcopy. 25133965Sjdp 25233965Sjdp* Added --defined-only argument to nm. 25333965Sjdp 25433965Sjdp* Added --remove-leading-char argument to objcopy. 25533965Sjdp 25633965Sjdp* The objdump --line-numbers option is now meaningful with --reloc. 25733965Sjdp 25833965Sjdp* Added --line-numbers option to nm. 25933965Sjdp 26033965Sjdp* Added --endian/-EB/-EL option to objdump. 26133965Sjdp 26233965Sjdp* Added support for Alpha OpenVMS/AXP. 26333965Sjdp 26433965SjdpChanges in binutils 2.6: 26533965Sjdp 26633965Sjdp* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. 26733965Sjdp 26833965Sjdp* Added several arguments to objcopy to provide some control over how the new 26933965Sjdp file is laid out in memory. Also added binary output format to BFD to permit 27033965Sjdp generating plain binary files. 27133965Sjdp 27233965Sjdp* Added --start-address and --stop-address options to objdump. 27333965Sjdp 27433965Sjdp* ar and ranlib now work on AIX. The tools are now built by default on AIX. 27533965Sjdp 27633965SjdpChanges in binutils 2.5: 27733965Sjdp 27833965Sjdp* Changed objdump -dr to dump the relocs interspersed with the assembly 279130561Sobrien listing, for a more useful listing of relocatable files. 28033965Sjdp 28133965Sjdp* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. 28233965Sjdp Added -D/--disassemble-all option to disassemble all sections. 28333965Sjdp 28433965Sjdp* Added --size-sort option to nm. 28533965Sjdp 28633965Sjdp* strip and objcopy should now be able to handle dynamically linked ELF 28733965Sjdp executables. 28833965Sjdp 28933965SjdpChanges in binutils 2.4: 29033965Sjdp 29133965Sjdp* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and 29233965Sjdp PowerPC (except ar and ranlib; by Ian Taylor). 29333965Sjdp 29433965Sjdp* Support for Irix 5. 29533965Sjdp 29633965Sjdp* Programs `strip' and `objcopy' will not attempt to write dynamically linked 29733965Sjdp ELF output files, since BFD currently can't create them properly. 29833965Sjdp 29933965SjdpChanges in binutils 2.3: 30033965Sjdp 30133965Sjdp* A new --stabs argument has been added to objdump to dump stabs sections in 30233965Sjdp ELF and COFF files. 30333965Sjdp 30433965Sjdp* A new program, nlmconv, has been added. It can convert object files into 30533965Sjdp Novell NetWare Loadable Modules. 30633965Sjdp 30733965Sjdp* The strings program has been added. 30833965Sjdp 30933965SjdpChanges in binutils 2.2: 31033965Sjdp 31133965Sjdp* The 'copy' program has been renamed to 'objcopy', for consistency with 31233965Sjdp 'objdump', and because 'copy' might more plausibly be used as a synonym for 31333965Sjdp 'cp'. 31433965Sjdp 31533965Sjdp* The new stand-alone program c++filt is a filter that converts encoded 31633965Sjdp (mangled) C++ assembly-level identifiers to user-level names. (Note: This 31733965Sjdp may get moved to the gcc distribution.) 31833965Sjdp 31933965Sjdp* nm -o on an archive now prefixes each line with the archive name, matching 32033965Sjdp the output from BSD nm. 32133965Sjdp 32233965Sjdp* ar (and ld) can now read (but not write) BSD4.4-style archives. 32333965Sjdp 32433965Sjdp* New support for H8500, Z8000, and the Hitach SH. 32533965Sjdp 32633965Sjdp* Dis-assembler interface changed to allow sharing with gdb. 32733965Sjdp 32833965Sjdp* There is new Elf code, but it is not yet ready for general use. 32933965Sjdp 33033965Sjdp* There is the beginnings of a test suite. 33133965Sjdp 33233965SjdpChanges in binutils 2.1: 33333965Sjdp 33433965Sjdp* There is now support for writing ECOFF files, so ld and the other utilities 33533965Sjdp should work on Risc/Ultrix and Irix. Please let us know how well this works. 33633965Sjdp 33733965Sjdp* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD 33833965Sjdp version), if there are any object files in the archive. So running ranlib is 33933965Sjdp now redundant (unless the non-standard q command is used). This is required 34033965Sjdp for Posix.2 conformance. 34133965Sjdp 34233965Sjdp* The archive-reading code now reads both BSD-style and SYSV-style archives 34333965Sjdp independently of the selected target format. This is to encourage people to 34433965Sjdp switch to SYSV-format, which has a number of advantages. 34533965Sjdp 34633965Sjdp* The strip and copy programs now have options to remove debug-symbols only 34733965Sjdp and/or local symbols only. They now also support long options. 34833965Sjdp 34933965Sjdp 35033965SjdpLocal variables: 35133965Sjdpfill-column: 79 35233965SjdpEnd: 353
