+* 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.
+
+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
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.
