public CachingSCCLBBFactory(LBBConverter lbbconv)

Creates a CachingSCCLBBFactory.

Method Detail

computeSCCLBB

public jpaul.Graphs.TopSortedCompDiGraph<LightBasicBlock> computeSCCLBB(HMethod hm)

Computes the topologically sorted graph of all the light basic blocks of the hm method. All the results are cached so that the computation occurs only once for each method (of course, unless clear is called).

Overrides:

computeSCCLBB in class SCCLBBFactory

clear

public void clear()

Clears the cache of previously computed results.
