\todo{uiCA} \medskip{}
Abel and Reineke, the authors of \uopsinfo{}, recently released
\uica{}~\cite{uica}, a code analyzer for Intel microarchitectures based on
\uopsinfo{} tables on one hand as a port model, and on manual
reverse-engineering through the use of hardware counters to model the frontend
and pipelines. We found this tool to be very accurate (see experiments later in
this manuscript), with results comparable with \llvmmca{}. Its source code
--~under free software license~-- is self-contained and reasonably concise
(about 2,000 lines of Python for the main part), making it a good basis and
baseline for experiments. It is, however, closely tied by design to Intel
microarchitectures, or microarchitectures very alike to Intel's ones.
