Dear LLVM, I was wondering if this is the right way to get TopDown DSGraph? TDDataStructures &TD = getAnalysis<TDDataStructures>(); F is some function DSGraph &dsg = TD.getDSGraph(F); I found out the DSGraph I got using this method is actually bottom up DSGraph, can you let me know why? Thanks, xiaodong

...rited from both ModulePass and the analysis group base class. That worked in LLVM 2.6, but now in LLVM 2.7 I'm getting strange behavior. In particular, I'm seeing the wrong functions called when virtual methods of my passes are called. For example, when a SAFECode pass would call the getDSGraph() method of the PoolAllocateSimple pass, the releaseMemory() method would be called instead. Has anyone else seen this really bizarre behavior or know what might be causing it? Eliminating multiple inheritance seems to fix the problem, but it seems to introduce other problems when chaining an...

Specifically we did the following: ...... DSGraph* DSG = getAnalysis<BUDataStructures>().getDSGraph( F ); std::map< Value*, DSNodeHandle> scalarmap = DSG->getScalarMap(); ...... The scalarmap is always empty. I printed the size of the map which came out to be zero always. But the getNodeForValue works correctly for the same DSG, which means that the scalarmap cannot be empty. But we a...

Chris, We tried that too...but still it returns an empty map. We also saw that Scalar Type has been removed from the DSNode types. Why is that?

Why do you think it's a BU graph? -Chris -- http://llvm.cs.uiuc.edu/ http://www.nondot.org/~sabre/Projects/

...v B: [ H int] Now X is represented ONLY in the scalar map, and it points to whatever the scalar points to. Because the scalar nodes don't exist in the graph anymore, we dropped the flag. -Chris > > > ...... > > > DSGraph* DSG = getAnalysis<BUDataStructures>().getDSGraph( F ); > > > std::map< Value*, DSNodeHandle> scalarmap = DSG->getScalarMap(); > > > ...... > > > > > > The scalarmap is always empty.
