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. + +Changes in 2.33: + +* Add --source-comment[=] option to objdump which if present, + provides a prefix to source code lines displayed in a disassembly. + +* Add --set-section-alignment = 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.
