When I tried to compile the program, I got this error: ../../../include/llvm/Analysis/DSGraph.h: In member function `virtual bool <unnamed>::GlobalMemLeakage::run(Module&)': ../../../include/llvm/Analysis/DSGraph.h:38: `void DSGraph::operator=(const DSGraph&)' is private MemLeakage.cpp:87: within this context gmake: *** [Debug/MemLeakage.o] Error 1 I don't u...

...Leakage.cpp:159: invalid conversion from `const DSNode*' to `DSNode*' MemLeakage.cpp:159: initializing argument 1 of `void <unnamed>::GlobalMemLeakage::KillSetInsert(DSNode*, BBsets&)' How to use a 'Node *' type iterator? Or is there any other way to traverse the DSGraph? thanks, Jerry On Sat, 16 Nov 2002, Bill?

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

Dear LLVM, I need to do interprocedural analysis for my project. I was wondering if you can tell me how to create Bottom Up DSGraph and Call Graph in the program. I know DSGraph *dsg = new DSGraph( F ) can create a DSGraph, but looks like that's only local DSGraph. I also need to know how to create the call graph for the whole module in the program. Thanks, xiaodong

Dear LLVM, If I have a DSGraph dsg, I want to duplicate a DSgraph which is exactly the same with dsg. How should I do that? Should I use DSGraph dsg2 = dsg; or use some other methods? Thanks, xiaodong

...nd from the dsg.dump() are different? Besides, each time I call the getAnaysis<TDDataStructure>(), it writes out some bu_funname.dot files to the disk. Why is that?

A note to people working on DSGraph related projects: I just checked in a bunch of fixes and minor changes that affect how the DSGraphs are built, and some minor representational fixes. With these changes, the DSGraph interface is pretty much frozen from my end. There are two big caveats though: 1. Bugs still exist. There are a...

I've been trying to obtain a DSGraph for a complete module, but haven't succeeded. I tried - getting the DSGraph for each function, and copying the nodes to a Module graph. But since there are no nodehandles, apparently there is no merging of nodes. - modifying BUDataStructure Pass so that it will not execute removeDeadNodes() o...

Yes, use the copy constructor. If you want mapping between the original and the new graph's nodes, you can also use this form of...

I've been trying to merge DSGraphs from different Functions, but i'm not going anywhere. For a Function F and DSGraph G, I tried this (assumming no SCC in the callgraph): vector<DSCallSite> CSV = G->getAuxFunctionCalls(); for (vector<DSCallSite>::iterator I = CSV.begin(), E = CSV.end(); I != E; I++) { Va...

Hi, I am using the DSA analysis in llvm-3.0. I am interested in seeing the resultant DSGraph for my sample input program. I tried the -dsa-only-print parameter, but was not successful in getting the .dot file for the graph as mentioned in Printer.cpp. The exact command that I tried is: #opt -load <path-to-llvmdatastructures.so> -dsa-local -dsa-bu -dsa-td -dsa-only-print < hello.b...

Hi, though DSA isn't maintained in the current build, I need to use it for analyzing dependencies among functions. Therfore I load the EQTDDataStructures pass and retrieve the mapping from nodes int the callee to the ones in the parent DSGraph with computeNodeMapping. In most cases this works well, but for some function calls I get following error: DSGraph.cpp:1379: static void llvm::DSGraph::computeNodeMapping(const llvm::DSNodeHandle&, const llvm::DSNodeHandle&, llvm::DSGraph::NodeMapTy&, bool): Assertion `Entry.getNode()...

I've been using DSGraph->dump() to get the DSGraph of some functions, but the report make little sense to me. I'm specially looking for the "N" flag mentioned by prof. vikram yesterday. How can I read the results (so that I can manually verify that my passes are making a good job) or there is some other...
