In this series I walkthrough the LLVM "Kaleidoscope" Tutorial, where you follow step by step to create your first programming language frontend using LLVM as the backend. Last time we wrote finished up writing the code for implementing the if statement, but hit a snag at the end. This time we go into full debug mode and try to get it working. Can it work? As a bonus, we also explain a little about the formulation of SSA form in the the output code, and why it isn't non-trivial in our case.
