描述

With GNU Binutils 2.34 comes debuginfod support, which is the HTTP server catching our eye while the debuginfod server is distributed as part of the latest elfutils package. This isn't for a general purpose web server thankfully but is an HTTP server for distributing ELF/DWARF debugging information and source code. With debuginfod enabled, Binutils' readelf and objdump utilities can query the HTTP server(s) for debug files that cannot otherwise be found. Enabling this option requires building Binutils using --with-debuginfod.

See https://developers.redhat.com/blog/2019/10/14/introducing-debuginfod-the-elfutils-debuginfo-server/ for more information.

研究方向
Investigate the debuginfod client library from elfutils (libdebuginfod) and how it is integrated in binutils. Review radare2's existing debug information handling and build system to determine where to add debuginfod support. Look at the official documentation and the redhat blog post for API details. Consider adding a configuration option with debuginfod similar to binutils.
