[llvm-dev] Live interval analysis on LLVM IR (not on Machine instructions)

     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 
     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,
