[$] Compact formats for debugging—and more

At the 2025 Linux Plumbers Conference in Tokyo, Stephen Brennan gave apresentation on the debuginfoformat, which contains the symbols and other information needed fordebugging, along with some alternatives. Debuginfo files are large and, hebelieves, are a bit scary to customers because of the "debug" in their name.By rethinking debuginfo and the tools that use it, he hopes thatfree-software developers "can add new, interesting capabilities to toolsthat we are already using or build new interesting tools".
