...quot;protocol" to be followed while using the function? DSGraph::getScalarMap returns a reference to the map, so this cannot be null. Do you mean that all of the "entries" in the map are null? If so, remember that DSGraphs are built in the context of some function (as indicated by hasFunction/getFunction), so only scalars in that context will be in the map... -Chris -- http://llvm.cs.uiuc.edu/ http://www.nondot.org/~sabre/Projects/

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
