| |
| Changes in 2.27: |
| |
| * Add a configure option, --enable-64-bit-archive, to force use of a |
| 64-bit format when creating an archive symbol index. |
| |
| * Add --elf-stt-common= option to objcopy for ELF targets to control |
| whether to convert common symbols to the STT_COMMON type. |
| |
| Changes in 2.26: |
| |
| * Add option to objcopy to insert new symbols into a file: |
| --add-symbol <name>=[<section>:]<value>[,<flags>] |
| |
| * Add support for the ARC EM/HS, and ARC600/700 architectures. |
| |
| * Extend objcopy --compress-debug-sections option to support |
| --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF |
| targets. |
| |
| * Add --update-section option to objcopy. |
| |
| * Add --output-separator option to strings. |
| |
| Changes in 2.25: |
| |
| * Add --data option to strings to only print strings in loadable, initialized |
| data sections. Change the default behaviour to be --all, but add a new |
| configure time option of --disable-default-strings-all to restore the old |
| default behaviour. |
| |
| * Add --include-all-whitespace to strings. |
| |
| * Add --dump-section option to objcopy. |
| |
| * Add support for the Andes NDS32. |
| |
| Changes in 2.24: |
| |
| * Objcopy now supports wildcard characters in command line options that take |
| section names. |
| |
| * Add support for Altera Nios II. |
| |
| Changes in 2.23: |
| |
| * Add support for the VLE extension to the PowerPC architecture. |
| |
| * Add support for x64 Windows target of the delayed-load-library. |
| |
| * Add support for the Renesas RL78 architecture. |
| |
| Changes in 2.22: |
| |
| * Add support for displaying the contents of .debug.macro sections. |
| |
| * Add --preprocessor-arg option to windres to specify additional options |
| passed to preprocessor. |
| |
| * Add --dwarf-start and --dwarf-end to readelf and objdump. These are used by |
| the new Emacs mode, see dwarf-mode.el. |
| |
| * Add support for the Tilera TILEPro and TILE-Gx architectures. |
| |
| changes in 2.21: |
| |
| * Add --interleave-width option to objcopy to allowing copying a range of |
| bytes from the input to the output with the --interleave option. |
| |
| * Add support for the TMS320C6000 (TI C6X) processor family. |
| |
| * Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using |
| the -u / --unwind option. |
| |
| * Add --dyn-syms to readelf to dump dynamic symbol table. |
| |
| * A new tool - elfedit - has been added to directly manipulate ELF format |
| binaries. |
| |
| * Add to dlltool .def file feature of aliasing PE internal symbol name by |
| '== <ID>' option. |
| |
| * Add a new command line option -a / --addresses to addr2line to display the |
| address before function name or source filename. |
| |
| * Add a new command line option -p / --pretty-print to addr2line to have |
| a more human readable output. |
| |
| * The hppa/som targets can now be compiled on any host. |
| |
| Changes in 2.20: |
| |
| * Add support for delay importing to dlltool. Use the --output-delaylib <file> |
| switch to create a delay-import library. The resulting app will load the dll |
| as soon as the first function is called. It will link to __delayLoadHelper2() |
| from the static delayimp library, which will import LoadLibraryA and |
| GetProcAddress from kernel32. |
| |
| * Add a new command line option, --insn-width=WIDTH, to objdump to specify |
| number of bytes to be displayed on a single line when disassembling |
| instructions. |
| |
| * Readelf can now display the relocated contents of a section as a sequence |
| of bytes via the --relocated-dump=<name|number> command line option. |
| |
| * The gprof program has been given a new command line option: |
| --external-symbols-table=<filename> which reads in symbols from a specified |
| file. |
| |
| * The plugin target has been added to bfd. It can load the same shared objects |
| used by gold and uses them to provide basic support for new file formats. |
| |
| * The verilog memory hex dump file format is now supported as an output format |
| for objcopy. |
| |
| * Add --file-alignment, --heap, --image-base, --section-alignment, |
| --stack and --subsystem command line options to objcopy, which will |
| set PE optional header. |
| |
| * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. |
| |
| * --as-needed now links in a dynamic library if it satisfies undefined |
| symbols in regular objects, or in other dynamic libraries. In the |
| latter case the library is not linked if it is found in a DT_NEEDED |
| entry of one of the libraries already linked. |
| |
| * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to |
| add absolute paths for -S. |
| |
| * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- |
| back to old import table generation with null element prefix. |
| |
| * Added --identify-strict switch to cause --identify <implib> to |
| report an error when the import library is associated with |
| multiple DLLs. |
| |
| * Added --identify <implib> option to dlltool, which determines the |
| name of the DLL associated with the specified <implib>. |
| |
| * Support for PowerPC booke64 instructions has been removed. The assembler no |
| longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts |
| -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. |
| |
| Changes in 2.19: |
| |
| * Added -wL switch to dump decoded contents of .debug_line. |
| |
| * Added support for "thin" archives which contain pathnames pointing to |
| object files rather than the files themselves and which contain a |
| flattened symbol index for all objects, and archives, which have been |
| added to the archive. |
| |
| * Added -F switch to objdump to include file offsets in the disassembly. |
| |
| * Added -c switch to readelf to allow string dumps of archive symbol index. |
| |
| * Support for SSE5 has been added to the i386 port. |
| |
| * Added -p switch to readelf to allow string dumps of sections. |
| |
| Changes in 2.18: |
| |
| * Resolved 37 coding problems in bfd including static array overruns, null |
| pointer dereferences and use of a malloc buffer after it has been freed, as |
| revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). |
| |
| * The binutils sources are now released under version 3 of the GNU General |
| Public License. |
| |
| * A new tool "windmc" has been added for some targets. This is a message |
| compiler which attempts to be compatible with the MS version. |
| |
| * Add codepage support to the windres tool. It now supports many new |
| resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation |
| for binary files is done now via bfd itself. The endianess problems |
| for different hosts are solved. Dumps of .res files can now be |
| re-compiled by windres without lossing resources or compilation errors. |
| Some problems on dialog resource translations are corrected. |
| |
| * Add --extract-symbol command line option to objcopy, which will |
| strip everything out of an ordinary object file or executable except |
| for its symbol table. Files containing just symbols can be useful |
| to some OSes. |
| |
| Changes in 2.17: |
| |
| * Add "-x NAME" to readelf in addition to "-x NUMBER". |
| |
| * Add -i and -t switches to cxxfilt. -i disables the display of implementation |
| specific extra demangling information (if any) and -t disables the demangling |
| of types. |
| |
| * Add support for the "@<file>" syntax to the command lines of all tools, so |
| that extra switches can be read from <file>. |
| |
| * Add "-W/--dwarf" to objdump to display the contents of the DWARF |
| debug sections. |
| |
| * Add "-t/--section-details" to readelf to display section details. |
| "-N/--full-section-name" is deprecated. |
| |
| * powerpc-linux ld now supports a variant form of PLT and GOT for the security |
| conscious. This form will automatically be chosen when ld detects that all |
| code in regular object files was generated by gcc -msecure-plt. The old PLT |
| and GOT may be forced by a new ld option, --bss-plt. |
| |
| * Add "-i/--inlines" to addr2line to print enclosing scope information |
| for inlined function chains, back to first non-inlined function. |
| |
| * Add "-N/--full-section-name" to readelf to display full section name. |
| |
| * Add "-M entry:<addr>" switch to objdump to specify a function entry address |
| when disassembling VAX binaries. |
| |
| * Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches |
| to objcopy to convert local symbols into global symbols. |
| |
| * gprof now allows input files to have histogram records for |
| several memory ranges, provided those ranges are disjoint. |
| |
| Changes in 2.16: |
| |
| * Add "-g/--section-groups" to readelf to display section groups. |
| |
| * objcopy recognizes two new options --strip-unneeded-symbol and |
| --strip-unneeded-symbols, namely for use together with the wildcard |
| matching the original --strip-symbol/--strip-symbols provided, but |
| retaining any symbols matching but needed by relocations. |
| |
| * readelf can now display address ranges from .debug_range sections. This |
| happens automatically when a DW_AT_range attribute is encountered. The |
| command line switch --debug-dump=Ranges (or -wR) can also be used to display |
| the contents of the .debug_range section. |
| |
| * nm and objdump now have a switch "--special-syms" to enable the displaying of |
| symbols which the target considers to be special. By default these symbols |
| are no longer displayed. Currently the only special symbols are the Mapping |
| symbols used by the ARM port to mark transitions between text and data and |
| between ARM and THUMB code. |
| |
| * dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional |
| import and export symbols with <preifx> prepended to them. |
| |
| Changes in 2.15: |
| |
| * objcopy for MIPS targets now accepts "-M no-aliases" as an option to the |
| disassembler to print the "raw" mips instruction mnemonic instead of some |
| pseudo instruction name. I.E. print "daddu" or "or" instead of "move", |
| "sll" instead of "nop", etc. |
| |
| * objcopy and strip can now take wildcard patterns in symbol names specified on |
| the command line provided that the --wildcard switch is used to enable them. |
| |
| * readelf can now parse archives. |
| |
| * objdump now accepts --debugging-tags to print the debug information in a |
| format compatible with ctags tool. |
| |
| * objcopy and strip now accept --only-keep-debug to create a file containing |
| those sections that would be stripped out by --strip-debug. The idea is that |
| this can be used in conjunction with the --add-gnu-debuglink switch to create |
| a two part program distribution - one a stripped executable and the other the |
| debugging info. |
| |
| * objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink |
| section into a (presumably stripped) executable. This allows the debug |
| information for the file to be held in a separate file. |
| |
| * BFD marks the sections .comment and .note as 'n' in the BSD/POSIX |
| single-character representation. This can be checked by running nm |
| with the -a switch. |
| |
| Changes in 2.14: |
| |
| * Added --info switch to objcopy and strip. |
| |
| * Support for Vitesse IQ2000 added by Red Hat. |
| |
| * Added 'S' encoding to strings to allow the display of 8-bit characters. |
| |
| * Added --prefix-symbols=<text>, --prefix-sections=<text> and |
| --prefix-alloc-sections=<text> to objcopy. |
| |
| * readelf can handle the extensions to the DWARF2 spec used by the Unified |
| Parallel C compiler. |
| |
| * BFD no longer declares a "boolean" type, to avoid clashes with other |
| headers that declare the same. Users of BFD should replace boolean, |
| false and true, with int, 0 and 1, or define their own boolean type. |
| |
| * Support for IP2K added by Denis Chertykov. |
| |
| Changes in 2.13: |
| |
| * Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 |
| and FR500 included. |
| |
| Changes in version 2.12: |
| |
| * Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
| |
| * size: Add --totals to display summary of sizes (Berkeley format only). |
| |
| * readelf: Add --wide option to not break section header or segment listing |
| lines to fit into 80 columns. |
| |
| * strings: Add --encoding to display wide character strings. By Markus Kuhn. |
| |
| * objcopy: Add --rename-section to change section names. |
| |
| * readelf: Support added for DWARF 2.1 extensions. Support added for |
| displaying the contents of .debug.macinfo sections. |
| |
| * New command line switches added to objcopy to allow symbols to be kept as |
| global symbols, and also to specify files containing lists of such symbols. |
| by Honda Hiroki. |
| |
| * Support for OpenRISC by Johan Rydberg. |
| |
| * New command line switch to objcopy --alt-machine-code which creates a binary |
| with an alternate machine code if one is defined in the architecture |
| description. Only supported for ELF targets. By Alexandre Oliva. |
| |
| * New command line switch to objcopy -B (or --binary-architecture) which sets |
| the architecture of the output file to the given argument. This option only |
| makes sense, if the input target is binary. Otherwise it is ignored. |
| By Stefan Geuken. |
| |
| * Support for PDP-11 by Lars Brinkhoff. |
| |
| Changes in binutils 2.11: |
| |
| * Add support for ARM v5t and v5te architectures and Intel's XScale ARM |
| extenstions. |
| |
| * Add --srec-len and --srec-forceS3 command line switch to objcopy. |
| By Luciano Gemme. |
| |
| * Support for the MIPS32, by Anders Norlander. |
| |
| * Support for the i860, by Jason Eckhardt. |
| |
| * Support for CRIS (Axis Communications ETRAX series). |
| |
| Changes in binutils 2.10: |
| |
| * Support for 64-bit ELF on HPPA. |
| |
| * New command line switch to objdump --file-start-context which shows the |
| entire file contents up to the source line first encountered for a given |
| file. |
| |
| * New command line switch to objdump -M (or --disassembler-options) which takes |
| a parameter which can then be interpreted on a per-target basis by the |
| disassembler. Used by ARM targets to select register name sets, ISA, APCS or |
| raw verions. |
| |
| * objdump support for -mi386:intel which causes disassembly to be displayed |
| with intel syntax. |
| |
| * New program: readelf. This displays the contents of ELF format files, |
| regardless of target machine. |
| |
| * objcopy now takes --change-section-lma, --change-section-vma, and |
| --change-section-address options. The old --adjust-section-vma option is |
| equivalent to --change-section-address. The other --adjust-* options are now |
| renamed to --change-*, although --adjust-* continues to work. |
| |
| * objcopy has a --redefine-sym option that lets you rename symbols. |
| |
| * objcopy now takes a -j/--only-section option to copy only the specified |
| sections. |
| |
| * dlltool now supports the IMPORTS command. |
| |
| * dlltool now takes --export-all-symbols, --no-export-all-symbols, |
| --exclude-symbols, and --no-default-excludes options. |
| |
| Changes in binutils 2.9: |
| |
| * Added windres program, which can be used to manipulate resources in WIN32 |
| files as used on Windows 95 and Windows NT. |
| |
| * The objcopy --gap-fill and --pad-to options operate on the LMA rather than |
| the VMA of the sections. |
| |
| * Added S modifier to ar to not build a symbol table. |
| |
| Changes in binutils 2.8: |
| |
| * The objdump disassembly format has been changed, and hopefully improved. Use |
| the new --prefix-addresses option to get the old format. There are also new |
| --disassemble-zeroes and --no-show-raw-insn options which affect disassembler |
| output. |
| |
| * Formats may now be specified as configuration triplets. For example, |
| objdump -b i386-pc-linux. The triplets are not passed through config.sub, |
| so they must be in canonical form. |
| |
| * Added new addr2line program. This uses the debugging information to convert |
| an address into a file name and line number within a program. |
| |
| * Added --change-leading-char argument to objcopy. |
| |
| * Added --weaken argument to objcopy. |
| |
| * objdump --dynamic-reloc now works on ELF executables and shared libraries. |
| |
| * Added --adjust-vma option to objdump. |
| |
| * Added -C/--demangle option to objdump. |
| |
| * Added -p/--preserve-dates option to strip and objcopy. |
| |
| Changes in binutils 2.7: |
| |
| * Added --enable-shared and --enable-commonbfdlib options to configure. |
| |
| * Added --debugging argument to objdump and objcopy. |
| |
| * Added --defined-only argument to nm. |
| |
| * Added --remove-leading-char argument to objcopy. |
| |
| * The objdump --line-numbers option is now meaningful with --reloc. |
| |
| * Added --line-numbers option to nm. |
| |
| * Added --endian/-EB/-EL option to objdump. |
| |
| * Added support for Alpha OpenVMS/AXP. |
| |
| Changes in binutils 2.6: |
| |
| * Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. |
| |
| * Added several arguments to objcopy to provide some control over how the new |
| file is laid out in memory. Also added binary output format to BFD to permit |
| generating plain binary files. |
| |
| * Added --start-address and --stop-address options to objdump. |
| |
| * ar and ranlib now work on AIX. The tools are now built by default on AIX. |
| |
| Changes in binutils 2.5: |
| |
| * Changed objdump -dr to dump the relocs interspersed with the assembly |
| listing, for a more useful listing of relocatable files. |
| |
| * Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. |
| Added -D/--disassemble-all option to disassemble all sections. |
| |
| * Added --size-sort option to nm. |
| |
| * strip and objcopy should now be able to handle dynamically linked ELF |
| executables. |
| |
| Changes in binutils 2.4: |
| |
| * Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and |
| PowerPC (except ar and ranlib; by Ian Taylor). |
| |
| * Support for Irix 5. |
| |
| * Programs `strip' and `objcopy' will not attempt to write dynamically linked |
| ELF output files, since BFD currently can't create them properly. |
| |
| Changes in binutils 2.3: |
| |
| * A new --stabs argument has been added to objdump to dump stabs sections in |
| ELF and COFF files. |
| |
| * A new program, nlmconv, has been added. It can convert object files into |
| Novell NetWare Loadable Modules. |
| |
| * The strings program has been added. |
| |
| Changes in binutils 2.2: |
| |
| * The 'copy' program has been renamed to 'objcopy', for consistency with |
| 'objdump', and because 'copy' might more plausibly be used as a synonym for |
| 'cp'. |
| |
| * The new stand-alone program c++filt is a filter that converts encoded |
| (mangled) C++ assembly-level identifiers to user-level names. (Note: This |
| may get moved to the gcc distribution.) |
| |
| * nm -o on an archive now prefixes each line with the archive name, matching |
| the output from BSD nm. |
| |
| * ar (and ld) can now read (but not write) BSD4.4-style archives. |
| |
| * New support for H8500, Z8000, and the Hitach SH. |
| |
| * Dis-assembler interface changed to allow sharing with gdb. |
| |
| * There is new Elf code, but it is not yet ready for general use. |
| |
| * There is the beginnings of a test suite. |
| |
| Changes in binutils 2.1: |
| |
| * There is now support for writing ECOFF files, so ld and the other utilities |
| should work on Risc/Ultrix and Irix. Please let us know how well this works. |
| |
| * ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD |
| version), if there are any object files in the archive. So running ranlib is |
| now redundant (unless the non-standard q command is used). This is required |
| for Posix.2 conformance. |
| |
| * The archive-reading code now reads both BSD-style and SYSV-style archives |
| independently of the selected target format. This is to encourage people to |
| switch to SYSV-format, which has a number of advantages. |
| |
| * The strip and copy programs now have options to remove debug-symbols only |
| and/or local symbols only. They now also support long options. |
