\item \staticdeps{}: set to also report \alert{register} dependencies.
|
|
\item Unroll $\kerK$ to fill the ROB
|
|
\item Build \alert{dependencies graph}: edges are dependencies,
|
|
weighted by \alert{source instruction latency} (given by \palmed).
|
|
\item Compute \alert{longest path}, divide by repetitions of $\kerK$
