 In \cref{sec:storing-pc}, we consider an issue arising from halfword-aligned instructions and the way a read of PC is interpreted under Thumb.
 \Cref{sec:code-addresses} discusses problems related to the fact that Thumb instruction addresses use bit 1 and should have bit 0 set for interworking,
 	while under ARM a branch will automatically clear both these bits.
+There was a minor problem with negative offsets to the \ual{ldr} instruction,
+	that cannot be as large in Thumb as they can in ARM.
+\Cref{sec:load-offsets} deals with this.
 
-The Thumb backend for Clean has been benchmarked.
-The results are collected and discussed in \cref{sec:results}.
+We benchmark the Thumb backend for Clean and discuss the results in \cref{sec:results}.
