Hi everyone, I'm currently trying to run a study on irreducibility of C programs, and I've implemented structural analysis (original paper by Sharir, algorithm in Muchnick's book) as an LLVM pass. When my implementation becomes a bit less buggy I'll certainly look into including it in the LLVM project. As a test for the algorithm I've been producing LLVM bitcode for C files

Hi, I am a new user of LLVM. I am using it as the IR for a compiler for a subset of LUA. I have the .ll file ready and it executes fine when passed to the llvm interpreter. Now, I wish to perform a few optimizations to the code starting with dead code elimination. For this I would need the CFG. I am very new to all of this stuff. Please help me out guys. The way I want to proceed is to start at
