+ <p>The ELF Tool Chain project provides BSD licensed
+ implementations of compilation tools and libraries for building
+ and analyzing ELF objects. It started as part of &os; but has
+ moved to a standalone project to encourage wider participation
+ from others in the open-source developer community. &os;'s
+ libelf and libdwarf are now imported from upstream source in
+ contrib/elftoolchain.</p>
+
+ <p>ELF Tool Chain provides a set of tools equivalent to the
+ GNU Binutils suite. This project's goal is to import these tools
+ into the &os; base system so that we have a set of up-to-date
+ and maintained tools that also provide support for new CPU
+ architectures of interest, such as arm64.</p>
+
+ <p>The following tools have now been imported and are available by
+ setting the src.conf knob WITH_ELFTOOLCHAIN_TOOLS=yes:</p>
+
+ <ul>
+ <li>addr2line</li>
+ <li>nm</li>
+ <li>size</li>
+ <li>strings</li>
+ <li>strip (elfcopy)</li>
+ </ul>
+
+ <p>A ports exp-run uncovered some bugs in these tools. The
+ bugs are being fixed in the &os; source tree and are in the
+ process of being committed to the upstream project.</p>
+
+ <p>ELF Tool Chain's readelf will be enabled as well once some
+ missing functionality in ELF note parsing is added. ELF Tool
+ Chain's elfcopy provides equivalent functionality to Binutils
+ objcopy, and accepts the same command-line arguments. For it to be
+ a viable replacement for all uses of objcopy in the base system it
+ will need to gain support for writing portable exectuable (PE)
+ format binaries, which are used in by UEFI boot code.</p>
+
+ <p>The ELF Tool Chain project does not currently provide
+ replacements for as, ld, and objdump. For &os; these tools will
+ likely be obtained from the LLVM project.</p>
