+* The MIPS port now supports the MIPS16e2 ASE for assembly and disassembly.
+
+* Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
+
+* Add support for the wasm32 ELF conversion of the WebAssembly file format.
+
+* Add --inlines option to objdump, which extends the --line-numbers option
+ so that inlined functions will display their nesting information.
+
+* Add --merge-notes options to objcopy to reduce the size of notes in
+ a binary file by merging and deleting redundant notes.
+
+* Add support for locating separate debug info files using the build-id
+ method, where the separate file has a name based upon the build-id of
+ the original file.
+
+Changes in 2.28:
+
+* This version of binutils fixes a problem with PowerPC VLE 16A and 16D
+ relocations which were functionally swapped, for example,
+ R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
+ performed like R_PPC_VLE_HA16A. This could have been fixed by
+ renumbering relocations, which would keep object files created by an
+ older version of gas compatible with a newer ld. However, that would
+ require an ABI update, affecting other assemblers and linkers that
+ create and process the relocations correctly. It is recommended that
+ all VLE object files be recompiled, but ld can modify the relocations
+ if --vle-reloc-fixup is passed to ld. If the new ld command line
+ option is not used, ld will ld warn on finding relocations inconsistent
+ with the instructions being relocated.
+
+* The nm program has a new command line option (--with-version-strings)
+ which will display a symbol's version information, if any, after the
+ symbol's name.
+
+* The ARC port of objdump now accepts a -M option to specify the extra
+ instruction class(es) that should be disassembled.
+
+* The --remove-section option for objcopy and strip now accepts section
+ patterns starting with an exclamation point to indicate a non-matching
+ section. A non-matching section is removed from the set of sections
+ matched by an earlier --remove-section pattern.
+
+* The --only-section option for objcopy now accepts section patterns
+ starting with an exclamation point to indicate a non-matching section.
+ A non-matching section is removed from the set of sections matched by
+ an earlier --only-section pattern.
+
+* New --remove-relocations=SECTIONPATTERN option for objcopy and strip.
+ This option can be used to remove sections containing relocations.
+ The SECTIONPATTERN is the section to which the relocations apply, not
+ the relocation section itself.
+
+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
* 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 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.
