\caption{\label{tab:feval} Speedup comparison for \feval\ optimization.}   \end{table}     Unfortunately, we are unable to compute direct performance metrics for the solution by Lameed and Hendren since its source code has not been released. Numbers in their paper~\cite{lameed2013feval} show that for these benchmarks the OSR-based approach yields a fraction of the speed-up from hand-coded calls on average equal to $30.1\%$ (ranging from $9.2\%$ to $73.9\%$); for the JIT-based approach this fraction grows to $84.7\%$ (ranging from $75.7\%$ to $96.5\%$). Our technique [...]
