+* The readelf tool now has a -L or --lint or --enable-checks option which turns
+ on warning messages about possible problems with the file(s) being examined.
+ These checks include things like zero-sized sections, which are allowed by
+ the ELF standard but which nevertheless might be of concern if the user
+ was expecting them to actually contain something.
+
+Changes in 2.34:
+
+* Binutils now supports debuginfod, an HTTP server for distributing
+ ELF/DWARF debugging information as well as source code. When built with
+ debuginfod, readelf and objdump can automatically query debuginfod
+ servers for separate debug files when they otherwise cannot be found.
+ To build binutils with debuginfod, pass --with-debuginfod to configure.
+ This requires libdebuginfod, the debuginfod client library. debuginfod
+ is distributed with elfutils, starting with version 0.178. For more
+ information see https://sourceware.org/elfutils.
+
+* Add --output option to the "ar" program. This option can be used to specify
+ the output directory when extracting members from an archive.
+
+* Add --keep-section option to objcopy and strip. This option keeps the
+ specified section from being removed.
+
+ * Add visualization of jumps inside a function by drawing an ascii character
+ graph between the address and the disassembler column. Enabled via the
+ --visualize-jumps command line option for objdump. Currently supported by
+ the x86, x86_64, and ARM targets. The output looks something like this:
+
+ c6: | | \----------> be 00 00 00 00 mov $0x0,%esi
+ cb: | | /----> 48 8b 3d 00 00 00 00 mov 0x0(%rip),%rdi # d2 <main+0xd2>
+ d2: | | | 31 c0 xor %eax,%eax
+ d4: | | | /-- e8 00 00 00 00 callq d9 <main+0xd9>
+ d9: | | | \-> bf 02 00 00 00 mov $0x2,%edi
+ de: | +-----------|----- e8 00 00 00 00 callq e3 <main+0xe3>
+ e3: | \-----------|----> 48 89 da mov %rbx,%rdx
+ e6: | | be 00 00 00 00 mov $0x0,%esi
+ eb: | \----- eb de jmp cb <main+0xcb>
+ ed: \-------------------> 48 8b 16 mov (%rsi),%rdx
+
+ Additional arguments to the --visualize-jumps option add colors to the
+ output.
+
+Changes in 2.33:
+
+* Add --source-comment[=<txt>] option to objdump which if present,
+ provides a prefix to source code lines displayed in a disassembly.
+
+* Add --set-section-alignment <section-name>=<align> option to objcopy to allow
+ the changing of section alignments.
+
+* Add --verilog-data-width option to objcopy for verilog targets to control
+ width of data elements in verilog hex format.
+
+* Add support for the Armv8.1-M Mainline and M-profile Vector Extension (MVE)
+ instructions.
+
+* The separate debug info file options of readelf (--debug-dump=links
+ and --debug-dump=follow) and objdump (--dwarf=links and
+ --dwarf=follow-links) will now display and/or follow multiple links if
+ more than one are present in a file. (This usually happens when gcc's
+ -gsplit-dwarf option is used).
+
+ In addition objdump's --dwarf=follow-links now also affects its other
+ display options, so that for example, when combined with --syms it will
+ cause the symbol tables in any linked debug info files to also be
+ displayed. In addition when combined with --disassemble the --dwarf=
+ follow-links option will ensure that any symbol tables in the linked
+ files are read and used when disassembling code in the main file.
+
+ * Add support for dumping types encoded in the Compact Type Format
+ to objdump and readelf.
+
+Changes in 2.32:
+
+* The addr2line, c++filt, nm and objdump tools now have a limit on the
+ maximum amount of recursion that is allowed whilst demangling strings.
+ The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
+ constant declared in the include/demangle.h header file. At the time
+ of writing this constant has the value of 2048.
+
+ The --no-recurse-limit option can be used to remove the limit, restoring
+ the behaviour of earlier versions of these tools. This may be needed in
+ order to dmangle truly complicated names, but it also leaves the tools
+ vulnerable to stack exhaustion from maliciously constructed mangled names.
+
+* Objdump's --disassemble option can now take a parameter, specifying the
+ starting symbol for disassembly. Disassembly will continue from this
+ symbol up to the next symbol or the end of the function.
+
+* The MIPS port now supports the Loongson 2K1000 processor which implements
+ the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE,
+ Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for
+ Loongson 2K1000 processor.
+
+* The MIPS port now supports the Loongson 3A2000/3A3000 processor which
+ implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE,
+ Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e
+ option for Loongson 3A2000/3A3000 processor.
+
+* The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a,
+ which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE
+ and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson
+ 3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
+ compatibility.
+
+* The size tool now has a new output format '--format=GNU' or '-G'. The
+ results are displayed in a similar manor to the default berkeley layout,
+ except read-only data is counted in the data column, not the text column.
+ Additionally the total is only included once.
+
+Changes in 2.31:
+
+* Add support for disassembling netronome Flow Processor (NFP) firmware files.
+
+* The AArch64 port now supports showing disassembly notes which are emitted
+ when inconsistencies are found with the instruction that may result in the
+ instruction being invalid. These can be turned on with the option -M notes
+ to objdump.
+
+* The AArch64 port now emits warnings when a combination of an instruction and
+ a named register could be invalid.
+
+* Added O modifier to ar to display member offsets inside an archive
+
+Changes in 2.30:
+
+* 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.
+
