+* Add --debug-dump=links option to readelf and --dwarf=links option to objdump
+ which displays the contents of any .gnu_debuglink or .gnu_debugaltlink
+ sections.
+
+ Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links
+ option to objdump which causes indirect links into separate debug info files
+ to be followed when dumping other DWARF sections.
+
+Changes in 2.29:
+
+* The MIPS port now supports microMIPS eXtended Physical Addressing (XPA)
+ instructions for assembly and disassembly.
+
+* The MIPS port now supports the microMIPS Release 5 ISA for assembly and
+ disassembly.
+
+* The MIPS port now supports the Imagination interAptiv MR2 processor,
+ which implements the MIPS32r3 ISA, the MIPS16e2 ASE as well as a couple
+ of implementation-specific regular MIPS and MIPS16e2 ASE instructions.
+
+* The SPARC port now supports the SPARC M8 processor, which implements the
+ Oracle SPARC Architecture 2017.
+
+* 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.
* 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.
+ several memory ranges, provided those ranges are disjoint.
Changes in 2.16:
* 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.
