Hello. Thank you very much for the research paper. I will try to make use of the algorithms it presents. I just want to add that I found a 3rd party project doing dataflow analysis for LLVM IR at https://github.com/rohitjha/cse231-proj2. As written at http://cseweb.ucsd.edu/~r1jha/#five , the project's description is: "Dataflow Analysis Framework for LLVM This is an extensible dataflow analysis framework for analyzing and optimizing LLVM IR code. The framework runs forward optimistic iterative dataflow analyses such as Constant Propagation, Available Expressi...

Could you

Hello. Could you please tell me how can I implement best a live interval analysis on LLVM IR (not on Machine instructions, which is already available in http://llvm.org/docs/doxygen/html/LiveIntervalAnalysis_8cpp_source.html)? I need to analyze the standard LLVM IR (list of Instruction *) and decide for each SSA variable what is it's live(ness) interval. My problem is that I
