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 don't even know of an existing general Dataflow analysis algorithm implementation for LLVM IR. Thank you, Alex
