Understanding the LLVM Compiler
Components of LLVM: LLVM is designed with a three-phase architecture: Frontend, Middle-end, and Backend. Each component plays a crucial role in translating high-level source code into machine-executable code, while allowing modularity and optimizations across different languages and architectures. 1. Frontend The frontend is responsible for: Parsing the high-level source code (written in languages like C, C++, Rust, etc.). Checking for syntax and semantic correctness. Generating the LLVM Intermediate Representation (IR), which is an abstract, platform-independent code representation. Key Processes in the Frontend: Lexical Analysis (Tokenization): The source code is broken into meaningful chunks called tokens (e.g.,…
