%by analyzing code at an intermediate representation level.  \end{enumerate}  \noindent A natural question is whether encoding OSR at a higher level of abstraction can result in poorer performance than binary code approaches. We address this issue in \mysection\ref{se:osr-llvm}, where we analyze the OSR machine code generated for an x86 x86-64  target, and in \mysection\ref{se:experiments}, where OSR performance is measured on classical benchmarks.
