Yeah, that was one of the first things I tried: for (Function::iterator i = function.begin(), e = function.end(); i != e; ++i) { BasicBlock *basicBlockPtr = &(*i); add_vertex(basicBlockPtr, timingGraph); } The "&(*i)" sure seems weird, but I don't know how else to grab a pointer to the BasicBlock from within the iterator. Also, if I then try to extract a vertex from the graph: BasicBlock *basicBlockPtr = timingGraph[0];...

Hi, LLVM provides basic graph traversal for its CFGs, but I need additional operations, such as iterating over the edges. I thought I would solve this problem using the Boost graph library. It should be relatively simple to walk an LLVM CFG and add the BasicBlock objects to a Boost graph declared as: typedef boost::directed_graph<llvm::BasicBlock> Graph; Once constructed, this

I could just create a loop pass as another opt and call that, I just thought it'd be easier to get the loop info inside the opt I'm already doing. It is

John, This did not work. It compiles (isDeclaration was the name of the function) and I passed a reference (&F) (F is a function pointer). I still get the opt load error from the original message (UNREACHABLE exectuted!). Thanks. On Thu, Nov 10, 2011 at 10:00 AM, Ryan Taylor <ryta1203 at gmail.com> wrote: > 1. Ok will do. > 2.
