\subsection*{The general context}

The standard debugging data format for ELF binary files, DWARF, contains a lot
of information. Among those are the stack unwinding data, which allows to
unwind stack frames, restoring machine registers to their proper values, for
instance within the context of a debugger.

As debugging data can easily get heavy beyond reasonable if stored carelessly,
the DWARF standard pays a great attention to data compactness and compression.
This, as always, is at the expense of efficiency: accessing stack unwinding
data for a particular program point can be quite costly.

The most widely used library used for stack unwinding,
\texttt{libunwind}~\cite{libunwind}, 

\subsection*{The research problem}

This internship explored the possibility to compile the standard ELF debugging
information format, DWARF, into x86\_64 assembly.
