------- Comment #14 from steven at gcc dot gnu dot org 2008-02-16 09:40 ------- For those who have no idea what we're talking about, check out these links. The first link is Tarjan's algorithm, which is what the tree-ssa-sccvn.c SCC-finder is based on. The second link is Pearce's improved algorithm. Ref. 6 from that paper is also of interest.
