+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.
