The text is using 'reader-writer lock' consistently, but a sentence in
tm.tex is missing the dash.  Add it.

 \item  Use TM strictly as an optimization in lock-based systems, as was
        done by the TxLinux~\cite{ChistopherJRossbach2007a} group,
        and as has been done by more recent work using TM to elide
-       reader writer locks~\cite{PascalFelber2016rwlockElision}.
+       reader-writer locks~\cite{PascalFelber2016rwlockElision}.
        This approach seems sound, at least on \Power{8}
        CPUs~\cite{Le:2015:TMS:3266491.3266500}, but leaves the locking
        design constraints (such as the need to avoid deadlock) firmly
