-Changes since binutils 2.7
+* 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.
-Changes since binutils 2.6
+* 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 support for Alpha OpenVMS/AXP.
-Changes since binutils 2.5
+Changes in binutils 2.6:
* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
* ar and ranlib now work on AIX. The tools are now built by default on AIX.
-Changes since binutils 2.4
+Changes in binutils 2.5:
* Changed objdump -dr to dump the relocs interspersed with the assembly
- listing, for a more useful listing of relocateable files.
+ 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.
* strip and objcopy should now be able to handle dynamically linked ELF
executables.
-Changes since binutils 2.3
+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).
* Programs `strip' and `objcopy' will not attempt to write dynamically linked
ELF output files, since BFD currently can't create them properly.
-Changes since binutils 2.2
+Changes in binutils 2.3:
* A new --stabs argument has been added to objdump to dump stabs sections in
ELF and COFF files.
* The strings program has been added.
-Changes since binutils 2.1
+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
* There is the beginnings of a test suite.
-Changes since binutils 2.0
+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.
