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> + </body> + + <sponsor>The &os; Foundation</sponsor> + + <help> + <task> + <p>Import readelf.</p> + </task> + + <task> + <p>Add missing functionality to readelf.</p> + </task> + + <task> + <p>Add missing functionality to elfcopy and migrate the base system + build.</p> + </task> + + <task> + <p>Fix issues found by fuzzing inputs to the tools.</p> + </task> + + <task> + <p>Switch the default to WITH_ELFTOOLCHAIN_TOOLS.</p> + </task> + </help> + </project> + </report>
