+* 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.
+
+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.
+ 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,
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.
and/or local symbols only. They now also support long options.
