Hi, Sorry for the last mail with wrong subject. I am a LLVM newbie, I have read some tutorials of LLVM, and play with some demos. I am developing a Hadoop native runtime, it has C++ APIs and libraries, what I want to do is to compile Hive's logical query plan directly to LLVM IR or translate Hive's physical query plan to LLVM IR, then run on the Hadoop native runtime. As far as I know,
