+Although there are several publications about tracing just-in-time compilers, to
 our knowledge, there are none that describe the use and implementation of
 guards in this context. With the following contributions we aim to shed some
 light (to much?) on this topic.

 \section{Related Work}
 
+SPUR~\cite{bebenita_spur:_2010} is a tracing JIT compiler
+for a C\# virtual machine.
+It handles guards by always generating code for every one of them
+that transfers control back to the unoptimized code.
+Since the transfer code needs to reconstruct the stack frames
+of the unoptimized code,
+the transfer code is quite large.
