remove the nodes in the SCC from the SCC map entirely prior to the DFS walk. This allows the SCC map to represent both the state of not-yet-re-added-to-an-SCC and added-back-to-this-SCC independently. The first is being missing from the SCC map, the second is mapping back to 'this'. In a subsequent commit, I'm going to use this property to simplify the new node list for this SCC. In theory, I think this also makes the contract for orphaning a node from the graph slightly less confusing. Now it is also orphaned from the SCC graph. Still, this isn't quite right either, and so I'm not adding test cases here. I'll add test cases for the behavior of orphaning nodes when the code *actually* supports it. The change here is mostly incidental, my goal is simplifying the algorithm. llvm-svn: 207213 |
