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

I'm toying with benchmarks on my HLVM and am unable to get any performance improvement from optimization passes. Moreover, some of my programs generate a lot of redundant code (e.g. alloca a struct, store a struct into it and read only one field without using the rest of the struct) and this does not appear to be optimized away. I simply copied the use of PassManager from the Kaleidoscope

Hello, I'd like to listen your opinions regarding my research with LLVM. My work is a dynamic analysis of data dependences [1]. Briefly speaking, I'm instrumenting memory loads/stores and loop entries/exits/back edges, and then calculating data dependences in runtime, especially focusing on loop-carried dependences. So far, I have been working with a binary-level instrumentation tool
