Implementing a Domain-Specific Language (DSL) with LLVM and C++

Tutorial February 12, 2025

  • Lexing & Parsing: Tokenizing input and building an AST using recursive-descent parsing.
  • AST & Code Generation: Creating an AST that maps directly to LLVM IR, enabling advanced optimizations.
  • Optimization & Execution: Leveraging LLVM’s optimization passes and setting the stage for JIT compilation.
  • Enhance the DSL: Add support for variables, functions, and control flow constructs.
  • Improve Error Handling: Develop a robust error recovery strategy in your parser.
  • Integrate JIT Execution: Use LLVM’s ORC JIT to compile and run your DSL expressions dynamically.
  • Experiment with Optimizations: Explore custom optimization passes and advanced LLVM features available in 2025.
