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

Thanks, Chris. Actually I got the following graph from my program: digraph DataStructures { label="Function fini"; edge [arrowtail="dot"]; size="10,7.5"; rotate="90"; Node0x100ae1c40 [shape=record,shape=Mrecord,label="{ %struct.a: HIMR\n|{<g0>|<g1>|<g2>}}"]; Node0x100ae1c40:g1 -> Node0x100ae1e00;

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

I use the following code to do the depth first search on the DSGraph. And I always got this error message. Couldn't figure out what's wrong. Could you please let me know? Besides, I really have no idea about what those functions do. Is there any documentation about DSGraph functions besides the pool allocation paper? Thanks, xiaodong Code: for( df_iterator<DSNode*> I =

Hello, I’m trying to port a project up to 4.0 and I’m seeing the following error: In file included from /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/StringRef.h:13: /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/STLExtras.h:139:13: error: no type named 'type' in 'std::__1::result_of<std::__1::pointer_to_unary_function<llvm::DSNode *, llvm::DSNode

When I check out llvm this morning. I got this error, so I couldn't check out. Looks like the disk is full.. Please let me know how to fix this problem.

Thanks Bill. One more question, when I use the DSNode iterator to traverse a node's children. The return value of I.getNode() can only be 'const DSNode *', I cannot use 'DSNode *' type. So as a result, I always get error message like this: MemLeakage.cpp:159: invalid conversion from `const DSNode*' to `DSNode*' MemLeakage.cpp:159: initializing argument 1 of `void

Dear Prof. Adve, I recently checked out the llvm using cvs update command under the llvm directory. But when I went to see the DSNode.h, there is no getPointerSize function. I checked the doxygen tree, it's there. So that means I didn't update my cvs tree correctly. Could you let me know how to update my CVS tree? Or there is a problem at somewhere else?

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

Just run one of these commands: analyze -datastructure x.bc -- local DSGs analyze -budatastructure x.bc -- BU DSGs analyze -tddatastructure x.bc -- TD DSGs These commands will output one

I have a question about the getNodeForValue() function. If I have the following code: struct a *p; p = malloc( sizeof(struct a)); If I call DSGraph->getNodeForValue(p).getNode(). Will the returned Node be p node or the actual memory location node? Thanks, xiaodong

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() or removeTriviallyDeadNodes(). - couldn't get

Why do you think it's a BU graph? -Chris

I was trying to call "DSGraph::computeCalleeCallerMapping" function on all caller-calle pair. But, in one case it gives an assertion failure. This is the error message I get.

Dear LLVM, When I use analyze to construct the DSGraph for the lists.c program in test/Programs/SingleSource/Shootout directory. I found out the heap node in the function test_list() all have type FOLDED:R. I was wondering why it's not heapnode anymore? My pass need to use this type information to determine whether a node is heap node. Is there any way I can know this is a heap node in this

I'm having trouble with using getAnalysis() to access the results of one pass from within another. I require the pass to be previously executed as follows: void MyPass::getAnalysisUsage(AnalysisUsage &Info) const { Info.addRequired<TDDataStructures>(); } Then I try to use it as follows: bool MyPass::doInitialization(Module &M) { TDDataStructures &dsgraph =
