LLVM-Lens: Open-Source Tool Visualizes the Full LLVM Compilation Pipeline
sh4dy_0011 · x · 2026-09-23
A team of developers released LLVM-Lens, an open-source LLVM Pass Transformation Analyzer that visualizes the C/C++ compilation pipeline. For each stage you can inspect LLVM IR changes, analyses run and invalidated, the CFG and other compilation graphs; it also supports the Machine IR pipeline, showing physical register allocation and spills. Every IR line maps back to C/C++ source via debug info, and built-in AI integration helps explain pass details. Repo is on GitHub.
