<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>
